    Assess the efficacy of the different strategies employed in the management of acute closure and verify the late prognosis of patients who develop this complication. From january 1987, through December 1990, 2315 consecutive patients underwent percutaneous transluminal coronary angioplasty (PTCA) in our Institution. We analyzed 100 patients who had had acute closure of the dilated vessel determining the total incidence of myocardial infarction and death, the effectiveness of the different treatment strategies and clinical and angiographic predictors of poor in-hospital outcome. Late follow-up was obtained in the hospital survivors. The incidence of acute myocardial infarction in the group of 100 patients was 57%; death occurred in 12% of the patients. Forty-one individuals were referred to emergency bypass surgery, 35 received clinical treatment and 24 underwent redilatation of the vessel. Those managed clinically had a higher incidence of myocardial infarction compared to the ones who underwent either redilatation or surgery (74.3% versus 50% and 48.8%). The in-hospital mortality rate was significantly higher in patients with left ventricular ejection fraction p > 0.05). Acute coronary occlusion is a serious complication of angioplasty and is associated with high rates of major complications (myocardial infarction, death). Low left ventricular ejection fraction and PTCA involving the left anterior descending are predictors of higher in-hospital mortality in patients with acute closure. Late outcome is less favourable in patients submitted to clinical treatment in the acute phase.

    The aim of our study was to evaluate the immediate results and long-term intake of anti-GP IIb / IIIa inhibitors for patients with acute coronary syndrome treated with coronary angioplasty. The use of anti-GP IIb / IIIa is a valid therapeutic option in patients with acute coronary syndrome with signs of severity and for patients undergoing complex angioplasty. Adverse effects of anti-GP IIb / IIIa can be seen to encourage vigilance and careful monitoring during the administration of these molecules and perfect knowledge of their pharmacological properties for appropriate use.

    To assess the efficacy of heparin in preventing the abrupt closure after coronary angioplasty in low risk patients for this phenomenon. In the last 4 years, 525 patients successfully dilated were randomized to receive intravenous heparin (n = 264) or not (n = 261) after the angioplasty. The excluding criteria were contraindications for heparin and risk for abrupt closure (refractory unstable angina, primary coronary angioplasty in acute myocardial infarction, evidence of intracoronary thrombus, intimal tear after the procedure and cases of chronic total occlusions). Both heparin and non heparin groups were similar in respect to female sex (15% x 17%; p = NS), age over 70 years old (7% x 9%; p = NS), previous myocardial infarction (26% x 24%; p = NS), multi-vessel procedures (4% x 7%; p = NS, stable angina (40% x 46%; p = NS), unstable angina (52% x 48%; p = NS) and angioplasty after thrombolytic therapy (8% x 6%; p = NS). The overall incidence of abrupt closure was 2/525 (0.4%), with one case (0.4%) in each group. The in-hospital mortality was 1/525 (0.2%), which occurred in a non-heparin patient, due to a anterior myocardial infarction. Major complications occurred similarly in heparin and non-heparin groups (0.4%). Bleeding complications were observed more frequently in the heparin group (7% x 2%; p = 0.002). All of them were in the catheterization site and none required blood transfusion. Severe systemic bleeding were not observed. In patients regarded as low risk for abrupt closure, the incidence of this complication was really low (0.4%) and heparin probably do not prevent it.

    Coronary angioplasty is used to treat coronary atherosclerotic disease in many patients. One problem with coronary angioplasty is the phenomenon of restenosis. Restenosis appears to be a universal response to arterial wall injury. The biological events that underlie restenosis are characterized by: platelet adhesion and aggregation at sites of damaged endothelium, and within dissections into the medial layers, release of platelet derived growth-promoting substances, inflammation of the injured medial zone, transformation, migration, and proliferation of smooth muscle cells of the media following their activation by growth-promoting substances, secretion of copious amounts of extracellular matrix material, and finally, termination of the growth process following regrowth of endothelium over the damaged area. More than a decade of research work has helped identify clinical correlates of restenosis after coronary angioplasty. Patient-related correlates include male gender, unstable angina, diabetes, and continued smoking after angioplasty. Lesion-related correlates include multilesion and multivessel procedures, higher post-angioplasty residual stenosis, proximal vessel location, location in the left anterior descending coronary artery, location in a vein graft, long lesions, and total occlusions. However, for the purposes of individual patient care, clinical correlates are not particularly helpful. No group of variables has predicted complete freedom from restenosis, and conversely no group of variables has reliably indicated its presence. All patients undergoing angioplasty will require some form of follow-up evaluation. Symptom status by itself has not been found to be useful for predicting restenosis. However, when symptom status is combined with exercise thallium-201 scintigraphy, performed 4-6 months after angioplasty, it is less than ideal, but has a negative predictive value of over 90%. This means that over 90% of patients who are asymptomatic and have no

    The purpose of this article is to review PTCA, percutaneous transluminal coronary angioplasty, which can be considered to be a truly revolutionary and fairly simple invasive form of intervention to atherosclerotic obstruction. The 'epidemic' of IHD, ischaemic heart disease, in the Republic of South Africa calls for the employment of this technique, which has already been carried out in a few teaching hospitals in this country. Very recently, modified balloon dilatation catheters have been used percutaneously in the non-operative transluminal correction of congenital coarctation of the aorta in infants and children, congenital pulmonary value stenosis, and hypoplasia and stenosis of the pulmonary arteries. It has also been employed for PTCA and for the simultaneous occlusion of coronary-bronchial artery anastomosis using a detachable balloon. The isotopes thallium 201 and technetium 99 were also used in scintiscanning

    Full Text Available Background. Predilection site for the acute myocardial infarction of the right ventricle, (AMI-RV is the upper third of the right coronary artery and for this reason such an infarction is followed by numerous complications, primarily by conduction disorders and very often by sudden and rapid cardiogenic shock development. Methods. Primary percutaneous transluminal coronary angioplasty (PPTCA was performed on three patients in whom the acute infarction of the right ventricular was diagnosed and who had been hospitalized six hours after the beginning of chest pain. In all three patients intracoronary stent was implanted. On the admission patients had been in the threatening cardiogenic shock, with the prominent chest pain and with the elevation of ST-segment in V4R>2 mV. In the course of intervention patients were administered low-molecular intracoronary heparin with direct platelet glycoprotein IIb/IIIa inhibitors (abciximab, according to the established procedure applied in such cases. Results. The complete dilatation of the infarcted artery was established with the signs of reperfusion and the further clinical course was completely normal, there was no heart failure and patients had no subjective difficulties. Conclusion. Invasive approach in the treatment of AMI-RV is justifiable, and possibly the therapy of choice of these patients, providing well trained and equipped team is available.

    To assess the relationship between leukocyte count, non invasive coronary flow reserve (CFR), left ventricular systolic function, and in-hospital adverse events in acute anterior myocardial infarction (AMI) treated by primary angioplasty. Leukocyte count at admission and within 24h after angioplasty, and differential count at admission were obtained in 72 consecutive patients with a first AMI (mean age 56±12 years) successfully treated by primary angioplasty. Transthoracic Doppler echocardiography was performed within 24h after angioplasty and 3 months later to assess the CFR (using intravenous adenosine), in the left anterior descending artery (LAD), left ventricular ejection fraction (LVEF) and the wall motion score index using the nine segments assigned to the LAD territory (WMSi-lad). In hospital events were defined as death, heart failure (Killip≥2) and reinfarction. Leukocyte count was higher before and after angioplasty in patients with impaired acute CFR (leukocyte, neutrophil and monocyte count (PLeukocyte (before and after angioplasty), and neutrophil count, were lower in patients with recovery of global and regional LV function (Pleukocyte count before and after angioplasty, and, initial and follow-up LVEF, and WMSi-lad (all, P≤0.01). Leukocyte (before and after angioplasty) and monocyte count were higher in patients with in-hospital events (n=14), by comparison to patients without events (all, Pleukocyte count after angioplasty was an independent predictor of CFR, and in-hospital events, and neutrophil count of WMSi-lad at follow-up (all, Pleukocyte count is inversely correlated to CFR, and global and regional LV systolic function at follow-up.

    To assess the efficacy of transluminal coronary angioplasty in patients with moderate (50-60%) coronary lesions. One hundred and thirty nine patients, 108 (78%) male, mean age was 55 years, who underwent coronary angioplasty from August 1983 to January 1989. Clinical findings included stable angina in 91 (65%) and unstable angina in 48 (35%). Single vessel disease was the case for 117 (84%), whereas 22 (16%) had two vessel coronary artery disease. Primary success rate was 130 (94%). All patients with two vessel disease had complete revascularization. In the failure group there were 2 acute myocardial infarction (1.4%), and 4 (2.8%) emergency coronary artery by-pass surgery. There were no in-hospital deaths. Of the 130 patients with success, 119 (92%) had late follow-up (mean time 31 months). At the end of the follow-up period we found 85 (71%) asymptomatic, while 27 (23%) had recurrence of symptoms. There were 2 late cardiovascular deaths. Fifty four patients underwent late angiography and 42 (78%) had maintenance of the result while 12 (22%) had restenosis, with a mean degree more severe than pre-coronary angioplasty. Coronary angioplasty of moderate lesions has a high success rate (94%); nevertheless the rate of major complications and restenosis is very similar to that of coronary angioplasty for severe stenosis. Such findings led us to reserve the indication of coronary angioplasty for moderate lesions for patients at higher risk with clear evidence of myocardial ischemia.

    To evaluate the use of primary coronary angioplasty (PTCA) in patients older than 70 years, evolving with acute myocardial infarction, without the previous administration of thrombolytic agents. Forty-two patients with acute myocardial infarction (AMI) and more than 70 years of age (m = 76.4y). There were 54.7% men and 43% of them had anterior MI. PTCA was carried out during the first 12 hours of evolution and in the first 3 hours of duration in 47% of them. PTCA was done only to the AMI related artery, which was the left descending artery in 43%, the right coronary artery in 47% and the left circumflex in the remaining patients. Nineteen percent of these patients were in Killip class III e IV. Primary success was achieved in 86%. The in hospital mortality was 14.2%, and it was superior in female gender (26.3%), in Killip class III and IV (37.5%), in those with multivessel coronary disease (16.6%) and in those where primary PTCA failed (33%). There were 9.3% of reinfarction, but no major hemorrhages happened. Late angiography was done in 50% of patients, showing 72% of patency in the AMI related artery, and a significant improval of global ejection fraction and of the wall motion, particularly, in those who maintained arterial patency. Primary PTCA, without former use of thrombolytic agents, when applied early in elderly patients evolving with AMI, has a high success rate and low mortality rate in this subset of high risk patients. It also shows no major hemorrhagic complications.

    Coronary lumen changes during and after excimer laser-assisted balloon angioplasty were measured by quantitative coronary angiography, and the results were compared with the effects of balloon angioplasty alone. Reduction of atherosclerotic tissue mass by laser ablation in the treatment of coronary artery disease may be more effective in enlarging the lumen than balloon angioplasty alone. A series of 57 consecutive coronary lesions successfully treated by xenon chloride excimer laser-assisted balloon angioplasty were individually matched with 57 coronary artery lesions successfully treated by balloon angioplasty alone. The following variables were measured by quantitative coronary analysis: 1) ablation by laser, 2) stretch by balloon dilation, 3) elastic recoil, and 4) acute gain. Matching by stenosis location, reference diameter and minimal lumen diameter resulted in two comparable groups of 57 lesions with identical baseline stenosis characteristics. Minimal lumen diameter before excimer laser-assisted balloon angioplasty and balloon angioplasty alone were (mean +/- SD) 0.73 +/- 0.44 and 0.74 +/- 0.43 mm, respectively. Laser ablation significantly improved minimal lumen diameter by 0.56 +/- 0.44 mm before adjunctive balloon dilation. In both treatment groups, similar-sized balloon catheters (2.59 +/- 0.35 and 2.56 +/- 0.40 mm, respectively) were used. After laser-assisted balloon angioplasty, elastic recoil was 0.84 +/- 0.30 mm (32% of balloon size), which was identical to that after balloon angioplasty alone, namely, 0.82 +/- 0.32 mm (32%). Consequently, both interventions resulted in similar acute gains of 1.02 +/- 0.52 and 1.00 +/- 0.56 mm, respectively. Minimal lumen diameter after intervention was equal in both groups: 1.75 +/- 0.35 and 1.75 +/- 0.34 mm, respectively. The statistical power of this study in which a 25% difference in elastic recoil (0.2 mm) between groups was considered clinically important was 95%. In matched groups of successfully treated

    The investigation included 56 patients with MI of lower localization and acute left ventricle failure (ALVF). Group A included 33 patients with primary coronary balloon angioplasty (PCBAP), in group B there were 23 patients with MI and ALVF without revascularization. Group A was divided into 2 subgroups--A1 (patients with history of IM) and A2 (patients without previous MI). On the first and on the 14th days echocardiographic investigation was performed in all the patients. Ejection fraction (EF) of the LV in dynamics by the 14th day of the disease increased in group A from 32.8 +/- 1.8% to 36.1 +/- 1.6% (p subgroup A2 (32.1 +/- 2.6% on the first day and 37.5% +/- 1.9 on the 14th day, p subgroup A1 there were no substantial changes of EF. In group B, on the contrary, there was decreased EF of the LV. Most of the group A patients had many injuries of the coronary bed vessels. After PCBAP of the right coronary artery (RCA) the increase of EF was followed by an improvement of the local contractility of the LV myocardium not only in the infarction zone, but also in the segments with ischemic dysfunction in which blood flows from the infarction-independent artery with its collateral filling from RCA.

    Full Text Available OBJECTIVE: To verify the results after the performance of primary coronary angioplasty in Brazil in the last 4 years. METHODS: During the first 24 hours of acute myocardial infarction onset, 9,434 (12.2% patients underwent primary PTCA. We analyzed the success and occurrence of major in-hospital events, comparing them over the 4-year period. RESULTS: Primary PTCA use increased compared with that of all percutaneous interventions (1996=10.6% vs. 2000=13.1%; p<0.001. Coronary stent implantation increased (1996=20% vs. 2000=71.9%; p<0.001. Success was greater (1998=89.5% vs. 1999=92.5%; p<0.001. Reinfarction decreased (1998=3.9% vs. 99=2.4% vs. 2000=1.5%; p<0.001 as did emergency bypass surgery (1996=0.5% vs. 2000=0.2%; p=0.01. In-hospital deaths remained unchanged (1996=5.7% vs. 2000=5.1%, p=0.53. Balloon PTCA was one of the independent predictors of a higher rate of unsuccessful procedures (odds ratio 12.01 [CI=95%] 1.58-22.94, and stent implantation of lower mortality rates (odds ratio 4.62 [CI=95%] 3.19-6.08. CONCLUSION: The success rate has become progressively higher with a significant reduction in reinfarction and urgent bypass surgery, but in-hospital death remains nearly unchanged. Coronary stenting was a predictor of a lower death rate, and balloon PTCA was associated with greater procedural failure.

    To evaluate the experience with the use of primary PTCA in the set of acute myocardial infarction (AMI) without the previous administration of thrombolytic agents. Two hundred and one patients with AMI, aged 35 to 86 years (mean = 57.2). There were 83.5% men. Twenty patients were older than 70 years and 48.2% had an anterior AMI. PTCA was performed early in the AMI, with a delay no longer than 12 hours. In 95%, it was done solely to the infarct related artery. Seventy percent patients were in Killip class I, 21% in class II, and 8% in classes III and IV (more than 50% of this subset of patients were in cardiogenic shock). Primary success was achieved in 84.5%. In hospital mortality was 5.9%, and there were 7% reinfarctions. Among the 84 patients who underwent a late cinecoronariography study, there were 19% restenosis and 8.3% reocclusions. In the long term follow up 75% were asymptomatic. Repeat PTCA was required in 10.2% of the cases, late coronary surgery was performed on 10.8% of the patients, and post-hospital cardiac mortality was 8.8% during an average follow up of 28 months (range 2-72 months). Primary PTCA is a effective way of reperfusion in the AMI, with a high primary success, low complications rate and without any major contraindications.

The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    , and translocation of bacteria from the oral cavity to the coronary arteries may play a role in the development of coronary artery disease. Very few studies have used angioplasty balloons for in vivo sampling from diseased coronary arteries, and with varying results. Therefore, the aim of this study was to assess...... if bacterial DNA from primarily oral bacteria could be detected on coronary angioplasty balloons by use of an optimized sampling process combined with an internally validated sensitive polymerase chain reaction (PCR) assay. Coronary angioplasty balloons and control samples from a total of 45 unselected...... patients with stable angina, unstable angina/non-ST elevation myocardial infarction, and ST-elevation myocardial infarction (n = 15 in each group) were collected and analyzed using a PCR assay with high sensitivity and specificity for 16S rRNA genes of the oral microbiome.

    Background: Distal embolization of thrombus/platelet aggregates decreases myocardial reperfusion during primary percutaneous coronary intervention (PCI), and is associated with worse immediate and long-term prognosis of patients with ST-elevation myocardial infarction (STEMI). Objective: Assess the efficacy of a mesh covered stent (MGuard™ stent, MGS) in preventing distal embolization and microvascular reperfusion impairment during primary PCI, compared with a bare metal stent (BMS). Methods: Forty patients with STEMI referred for primary PCI were randomized for stenting the culprit lesion with the MGS (n = 20) or a BMS (n = 20). Blinded experts performed off-line measurements of angiographic epicardial and microvascular reperfusion criteria: TIMI flow grade, myocardial blush, corrected TIMI frame count (cTFC). Results: At baseline clinical, angiographic and procedural variables were not different between groups. Post PCI TIMI flow grade was similar in both groups. We observed better myocardial Blush grade in group MGS compared to BMS (median value 3.0 vs 2.5, 2p = 0.006) and cTFC (mean cTFC: MGS 19.65 ± 4.07 vs BMS 27.35 ± 7.15, 2p < 0.001, cTFC mean difference MGS-BMS: 7.7, CI 95%: 3.94 to 11.46). MGS stent group had a higher percentage of successful angioplasty (cTFC ≤ 23: MGS 85% vs BMS 30%, 2p < 0.001). We had two cases of acute stent thrombosis (one for each group) at 30 days follow up, but no clinical events at 6 months follow up. Conclusions: In this exploratory study, MGS significantly improved microvascular reperfusion criteria compared with a BMS in primary PCI. However its safety and impact on clinical outcomes should be verified in larger randomized clinical trials.

    Optical Coherence tomography (OCT) is a light-based imaging modality which shows tremendous potential in the setting of coronary imaging. Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome (ACS). The diagnosis of SCAD is made mainly with invasive coronary angiography, although adjunctive imaging modalities such as computed tomography angiography, IVUS, and OCT may increase the diagnostic yield. The authors describe a clinical case of a young woman admitted with the diagnosis of ACS. The ACS was caused by SCAD detected in the coronary angiography and the angioplasty was guided by OCT. OCT use in the setting of SCAD has been already described and the true innovation in this case was this unique use of OCT. The guidance of angioplasty with live and short images was very useful as it allowed clearly identifying the position of the guidewires at any given moment without the use of prohibitive amounts of contrast.

    Six hundred ninety-nine patients have required emergency coronary artery bypass after failed elective percutaneous coronary angioplasty during the decade September 1980 through December 1990. This represents 4% of 9860 patients having 12,146 elective percutaneous coronary angioplasty procedures during this interval. Emergency coronary artery bypass was required for acute refractory myocardial ischemia in 82%. Hospital mortality rate for all patients was 3.1%; 3.7% in patients with refractory myocardial ischemia but 0.8% in patients without refractory myocardial ischemia, p = 0.08. Postprocedural Q-wave myocardial infarctions were observed in 21% versus 2.4%, p less than 0.0001, and intra-aortic balloon pumping was required in 19% with versus 0.8% without refractory myocardial ischemia, p less than 0.0001. Multivessel disease, p = 0.004, age older than 65 years, p = 0.005, and refractory myocardial ischemia, p = 0.08, interacted to produce the highest risk of in-hospital death. Follow-up shows that there have been 28 additional late deaths, including 23 of cardiac causes for a 91% survival at 5 years. Freedom from both late death and Q-wave myocardial infarction at 5 years was 61%. In the group going to emergency coronary artery bypass with refractory myocardial ischemia, the late cardiac survival was 90%, and in those without ischemia, 92% at 5 years, p = not significant. The MI--free survival in the group with refractory ischemia, however, was 56% versus 83% in the group without ischemia, p less than 0.0001. Multivariate analysis showed the highest late event rates for patients with Q-wave myocardial infarction at the initial emergency coronary artery bypass, age older than 65 years, angina class III or IV, and prior coronary bypass surgery. In spite of a continuing high incidence of early acute myocardial infarction and an increasing operative mortality rate (7%) in the latest 3 years cohort of patients, excellent late survival and low subsequent cardiac event

    During more than five years of investigation with excimer laser angioplasty, several changes have been made in patient selection and laser catheters. It is unclear, however, whether these changes have improved the outcome of excimer laser angioplasty. A total of 2041 patients underwent treatment with excimer laser coronary angioplasty for 2324 lesions with clinical success in 89%, ischemic complications in 7.5%, and vessel perforation in 2.1%. When the entire 5-year period of investigation was divided into four discrete phases, as defined by the successive release of improved laser catheters (prototype, flexible, extremely flexible, and eccentric), clinical success was seen to improve from 86% to 95% (page (pequals0.01) and unstable angina (pdecreased complications. Reduced catheter size relative to vessel size was associated with decreased risk of vessel perforation. Thus, refinements in patient selection and in laser technique have been associated with enhanced safety and efficacy of excimer laser angioplasty.

    New low profile balloon catheter have allowed the indication of percutaneous transluminal coronary angioplasty (PTCA) for more complex lesions. We report our initial experience with these systems in 50 out of 101 patients (50%) who underwent a PTCA from March 15 to May 15, 1989 in "Instituto Dante Pazzanese de Cardiologia". Mean age was 58.6 +/- 10.4 years and most of the patients were male (78%). We dilated 54 lesions. Single vessel disease was the case for 84% of the patients. As for the localization of the lesions in the coronary arteries, 56% of the lesions were in the proximal or mid segments of the coronary arteries and the mean diameter stenosis pre-PTCA was 84 +/- 10.2%. Left ventricular function was normal in 60% of the patients. Primary success rate (per patient) was 95% and the coronary stenosis was crossed in all the cases. The mean inflation number was 2.7 +/- 0.6 per patient, the mean highest pressure was 8 +/- 1.15 atm and the mean maximum time of inflation was 86.1 +/- 29.6 sec. The mean residual stenosis was 15.2 +/- 10.6%. There was only one major complication, namely an acute myocardial infarction of the lateral wall. There were no emergency CABG surgery or deaths. We conclude that the new low profile balloon catheters have broadened the indication for PTCA in more complicated lesions, showing a high rate of primary success (95%), but did not increase the number of procedural complications (2.5%).

    In August 2005, New Orleans was hit by Hurricane Katrina, the costliest natural disaster in US history. Previous studies have shown an increase in acute myocardial infarction (AMI) in the immediate hours to weeks after natural disasters. The goals of our study were to detect any long-term increase in the incidence of AMI after Katrina and to investigate any pertinent contributing factors. This was a single-center retrospective cohort observational study. Patients admitted with AMI to Tulane Health Sciences Center hospital in the 2 years before Katrina and in the 2 years after the hospital reopened (5 months after Katrina) were identified from hospital records. The 2 groups (pre- and post-Katrina) were compared for prespecified demographic and clinical data. In the post-Katrina group, there were 246 admissions for AMI, out of a total census of 11,282 patients (2.18%), as compared with 150 AMI admissions out of a total of 21,229 patients (0.71%) in the pre-Katrina group (P affected (P housing (P = 0.003). The role of chronic stress in the pathogenesis of AMI is poorly understood, especially in the aftermath of natural disasters. Our data suggest that Katrina was associated with prolonged loss of employment and insurance, decreased access to preventive health services, and an increased incidence of AMI. In addition, it appears that chronic stress after a natural disaster can be associated with tobacco abuse and medication and therapeutic noncompliance. We found a 3-fold increased incidence of AMI more than 2 years after Hurricane Katrina. Even allowing for the loss of some local hospitals after the disaster, this represents a significant change in overall health of the study population and supports the need for further study into the health effects of chronic stress.

    The objective of this study was to determine the optimal time to assess microvascular integrity within the risk area for myocardial infarction in order to predict unfavorable left ventricular remodeling (LVR) after successful primary coronary angioplasty. Fifty-three patients who underwent myocardial contrast echocardiography (MCE) just before recanalization, shortly after and 1 day (Day 2) and 3 weeks after recanalization were studied. The no- and low-reflow ratio (LR ratio) was analyzed at each stage. The wall-tinning ratio within the risk area was determined using magnetic resonance imaging performed 3-4 weeks after the recanalization. Thirteen of the 53 patients showed LVR 3-8 months after recanalization. The optimal time to predict LVR was found to be Day 2 based on the receiver operating characteristic curves. The LR ratio on Day 2 (χ 2 =7.39, p=0.007) and the collateral circulation before recanalization (χ 2 =4.57, p=0.03) were chosen as independent variables for predicting LVR. Patients with greater than 0.43 in the LR ratio on Day 2 showed a lower wall-thinning ratio (58±19% vs 72±20%, p=0.05). This study shows that the optimal time to estimate the microvascular integrity for predicting LVR is 1 day after recanalization, which is neither shortly after recanalization nor during the convalescent stage.

    A strategy combining percutaneous coronary angioplasty followed by valvular and/or coronary surgery was recently proposed as an alternative to the classical surgical only approach. The aim of this study was to assess the feasibility and the results of such a combined strategy with the two procedures performed the same day. The population comprised 34 patients including 17 with valvular disease and revascularisable coronary lesions (15 symptomatic severe aortic stenoses and two acute mitral insufficiencies) plus 17 multitrunk coronary patients without valvular disease but with an indication for revascularisation. Angioplasty was performed several hours prior to surgery and a loading dose of 300mg clopidogrel was administered immediately postoperatively; all patients were on aspirin before the procedure. The average age was 67 +/- 11 years, NYHA class 2.3 +/- 0.7, angina 73%, LVEF 58 +/- 10%. Single coronary artery disease was present in 26%, two vessel disease in 35% and three vessel disease in 39%. The success rate for angioplasty plus stent was 98%. 60 stents were active. Bypasses were exclusively arterial (left or right internal mammary arteries). We observed 4 in-hospital deaths, one of which was due to an infarct and three due to extra-cardiac causes (1 non-cardiogenic acute respiratory distress syndrome, 1 respiratory tract infection and 1 pyelonephritis). Further surgery was necessary in 4 cases: for haemorrhage and one episode of digestive tract haemorrhage. There were no additional deaths, coronary events nor haemorrhage at the end of an average follow-up of 15 +/- 6 months. The results of this combined strategy are encouraging in this population and merit further evaluation in a prospective study.

    Fifty-four asymptomatic patients with positive thallium exercise tests underwent coronary angiography followed by coronary angioplasty (PTCA), as the primary therapy for silent ischemia. The procedure was technically successful in 89% of these patients. Emergency bypass graft surgery was necessary in 2 (3.6%) and q-wave myocardial infarction occurred in 1 (1.8%) of these. All fifty-four patients have been followed for a mean of 35 months since angioplasty. Of the 48 patients with initially successful PTCA, 12 had either clinical restenosis (9/14 or 19%) or a new lesion (3/48 or 6%) during follow-up, which required a repeat PTCA. At the longest follow-up, 46 (85%) had been successfully treated with on or more PTCA procedures. Two patients (3.6%) had sustained late q-wave myocardial infarction and two additional patients reported angina pectoris. There were no deaths. Angioplasty as a primary therapy for silent ischemia appears efficacious, with success and restenosis rates comparable to those in the symptomatic population. Event-free survival is improved, compared with natural history data for patients with silent ischemia from other studies. Prudent risk/benefit analysis may help to define subgroups most likely to benefit from this intervention

    Contrast-induced acute kidney injury (CI-AKI) is a complex syndrome of acute renal failure occurring after the administration of contrast media and contributing to prolonged hospital stay and mortality. The risk of CI-AKI is higher among patients undergoing primary percutaneous coronary interventions for acute myocardial infarction (AMI), but its clinical relevance in such setting has only been evaluated by small sample size single-center studies and retrospective or observational analyses. Furthermore, whereas high-osmolar contrast media was shown to have direct nephrotoxicity, the role of low-osmolar and iso-osmolar agents is still debated. The CONTRAST-AMI study is a prospective, multicenter, controlled, randomized, single-blind, parallel-group trial, designed to show the noninferiority of the effects of iopromide (low-osmolar) compared with iodixanol (iso-osmolar) contrast media on the incidence of CI-AKI and tissue-level perfusion in patients with AMI. All consecutive patients admitted to participating centers for ST-segment elevation AMI undergoing primary percutaneous coronary intervention will be enrolled. All patients will be treated with high-dose N-acetylcysteine (1200 mg intravenously during the procedure and 1200 mg orally two times daily for the next 48 h after percutaneous coronary intervention) and hydration according to a standardized protocol. The primary endpoint is the proportion of patients with a relative increase in serum creatinine (sCr) of at least 25% from baseline to 72 h after agent administration. The secondary endpoints are absolute and relative increases in sCr of at least 50%, thrombolysis in myocardial infarction (TIMI) perfusion grade, and major adverse cardiac events at 1, 6, and 12 months. The CONTRAST-AMI study will provide information on the effects of iodixanol and iopromide on the incidence of CI-AKI and tissue-level perfusion in patients with AMI.

    The chest pain can be use for stratifying the risk of the patients after coronary angioplasty. Nevertheless this strategy has shown to have a low accuracy in the detection of restenosis and myocardial ischemia. Aims: To establish the usefulness of the SPECT studies in the risk stratification after the coronary angioplasty. Evaluate the incidence of silent ischemia or symptomatic, and its impact on the prognosis. Method: There were included 107 patients (p) submitted to a gated SPECT between the year of the coronary angioplasty. The analysis of the images was performed according to different scores (SSS, SRS, SDS). These data was correlated with the symptoms of the patients. We define group 1 (G1) as the asymptomatic without ischemia (n 59p), group 2 (G2) as silent ischemia (n = 28p) and group 3 (G3) as symptomatic with ischemia (n = 20p). A clinical follow-up was done in search of events (target vessel revascularization, unstable angina, AMI and death). Results: Significant differences were not observed in the clinical variables between the different groups. The SSS was lower in the G1 compare with G2 and G3 (p 0.0001) and was similar between the last two, p = NS (SSS: G1: 2.2 ± 4.9; G2: 7.6 ± 5.9; G3: 9.5 ± 6.8). The SDS was greater in G3 vs. G1 and G2, p = 0.0001, and greater in G2 vs. G1, p = 0.0001 (SDS: G1: 0; G2: 4.8 ± 3.5; G3: 7.2 ± 6.5). No differences where observed in the SRS between the three groups. In the follow-up the total percentage of events was lesser when compare the G1 with the G2 and G3 (G1: 3.3%; G2 and G3: 18.7%; p 0.02). The percentage of annual events of the G3 symptomatic with ischemia (11.03%) and G2 silent ischemia (4.04%) did not present differences (p 0.7). When the events of the G2 (4.04%) were compared with the G1 (1.24%) we observed a trend to major frequency of events in the G2 (p = 0.6). Conclusions: The presence of myocardial ischemia after coronary angioplasty is a determinant of the prognosis. Nevertheless, the extension

    The goal of this study was to determine the effects of exercise training (ET) on functional capacity and quality of life (QOL) in patients who received percutaneous transluminal coronary angioplasty (PTCA) or coronary stenting (CS), the effects on the restenosis rate and the outcome. It is unknown whether ET induces beneficial effects after coronary angioplasty. We studied 118 consecutive patients with coronary artery disease (mean age 57+/-10 years) who underwent PTCA or CS on one (69%) or two (31%) native epicardial coronary arteries. Patients were randomized into two matched groups. Group T (n = 59) was exercised three times a week for six months at 60% of peak VO2. Group C (n = 59) was the control group. Only trained patients had significant improvements in peak VO2 (26%, p < 0.001) and quality of life (26.8%, p = 0.001 vs. C). The angiographic restenosis rate was unaffected by ET (T: 29%; C: 33%, P = NS) and was not significantly different after PTCA or CS. However, residual diameter stenosis was lower in trained patients (-29.7%, p = 0.045). In patients with angiographic restenosis, thallium uptake improved only in group T (19%; p < 0.001). During the follow-up (33+/-7 months) trained patients had a significantly lower event rate than controls (11.9 vs. 32.2%, RR: 0.71, 95% confidence interval [CI]: 0.60 to 0.91, p = 0.008) and a lower rate of hospital readmission (18.6 vs. 46%, RR: 0.69, 95% CI: 0.55 to 0.93, p < 0.001). Moderate ET improves functional capacity and QOL after PTCA or CS. During the follow-up, trained patients had fewer events and a lower hospital readmission rate than controls, despite an unchanged restenosis rate.

    The nature and outcome of treatment for acute myocardial infarction in elderly patients admitted to Spanish hospitals with primary angioplasty facilities are not well documented. Prospective analysis of registry data on patients > or =75 years old with ST-segment-elevation acute myocardial infarction admitted between April and July 2002 to Spanish hospitals with an active primary angioplasty program. We followed up 410 consecutive patients for 1 month. Their mean age was 80 (4.3) years and 46% were female. The median delay between symptom onset and arrival at hospital was 190 minutes. Around 42% of patients received no reperfusion therapy, 35% were treated by thrombolysis, and 22% by primary angioplasty. Patients who underwent reperfusion therapy were younger, were more frequently male, had a shorter delay from symptom onset to hospital arrival, and had a better initial hemodynamic status (Killip Class). However, they were more likely to have extensive anterior infarctions. Overall, 30-day mortality was 24.9%. Independent predictors of death were age, systolic blood pressure, and Killip class >1, but not use of thrombolysis or primary angioplasty. Over 42% of elderly patients with myocardial infarction admitted to Spanish hospitals with angioplasty facilities did not receive reperfusion therapy. Thrombolysis was the most frequently used reperfusion therapy. However, neither thrombolysis nor primary angioplasty improved 30-day mortality.

    Transluminal coronary angioplasty (TCA) was introduced in 1977 for dilatation of coronary stenoses. From October 1977 to December 1984 1087 procedures have been performed in Frankfurt. The mean success rate was 77% with an increase from 58% to 84% since 1977. Recurrences were seen within the first year in 15% of the patients, which could be treated successfully in a high percentage with a second TCA. Emergency bypass operations were necessary in 5.2%. Four patients (fatality rate 0.37%) died as the consequence of the intervention. Within few years TCA has become an established procedure for myocardial revascularisation, with a high success rate. Major progress has been possible in the last few years due to technical developments, which are still going on. They may lead to further improvement of the results and enlargement of the indication for TCA. (orig.) [de

    A 46-year-old woman was referred to our hospital due to chest pain. Twelve-lead electrocardiogram revealed ST-segment elevation suggesting acute myocardial infarction. Emergent coronary angiography showed diffuse narrowing and occlusion in the middle to distal left anterior descending artery (LAD). To investigate the cause of occlusion, an intravascular ultrasound (IVUS) examination was performed and we diagnosed spontaneous coronary artery dissection (SCAD) as the cause of occlusion. After a cutting balloon was dilated at the distal LAD, coronary flow recovered. IVUS-guided angioplasty with cutting balloon could be a choice of treatment in SCAD patients who need revascularization.

    Nuclear techniques studies of the heart represent one of the fastest growing areas of research. Several years ago, nuclear medicine cardiac studies were limited for the evaluation and diagnosis of myocardial infarction. Development in radiopharmaceutical-chemistry and instrumentation have made possible advances in nuclear medicine for restenosis cardiovascular therapy after percutaneous transluminal coronary angioplasty.The radionuclide as radiation source can be delivered to the target basically by two techniques, those are catheter-based systems and radioactive stents. For this purpose,it can be use the γ and β emitter radionuclides, in which the β emitter radionuclides is an ideal radionuclide for endovascular therapy. Restenosis after percutaneous transluminal coronary angioplasty can be prevented by using the radioactive stent. This review discusses several techniques which could be used for restenosis cardiovascular therapy. Furthermore, several types of radiopharmaceutical and kinds of radionuclides as well as doses of the compounds for this purpose are also reviewed. (author)

    Heart patients who have undergone a coronary bypass may present with renewed myocardial ischemia, often connected with bypass dysfunction. The saphenous bypass is the most frequently implicated, and palliative revascularization may be envisaged, either by further bypass surgery, or by angioplasty. The latter approach has been developed since the beginning of the 1980s, and since that time there has been considerable technical and pharmacological progress in performing this type of graft. However the indications for angioplasty and its comparison with reoperation remain controversial. In the present study, it therefore seemed pertinent to include the respective opinions of two experts in the field of angioplasty and coronary bypass surgery.

    Aim: An innovative xenon–chlorine (excimer) pulsed laser catheter (ELCA X80) has been recently used for the treatment of complex coronary lesions, as calcified stenosis, chronic total occlusions and non-compliant plaques. Such complex lesions are difficult to adequately treat with balloon angioplasty and/or intracoronary stenting. The aim of this study was to examine the acute outcome of this approach on a cohort of patients with coronary lesions. Methods and Results: Eighty patients with 100 lesions were enrolled through four centers, and excimer laser coronary angioplasty was performed on 96 lesions (96%). Safety and effectiveness data were compared between patients treated with standard laser therapy and those treated with increased laser therapy. Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success in was obtained in 87 lesions (90.6%). There was no perforation, major side branch occlusion, spasm, no-reflow phenomenon, dissection nor acute vessel closure. Increased laser parameters were used successfully for 49 resistant lesions without complications. Conclusions: This study suggests that laser-facilitated coronary angioplasty is a simple, safe and effective device for the management of complex coronary lesions. Furthermore, higher laser energy levels delivered by this catheter improved the device performance without increasing complications. - Highlights: • We planned this multicenter study to examine the acute outcome of an innovative xenon–chlorine (excimer) pulsed laser catheter (ELCA X80) for treatment of complex coronary lesions. • We enrolled 80 patients with 100 lesions and performed excimer laser coronary angioplasty in 96 lesions (96%). • Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success was obtained in 87 lesions (90.6%). • Increased laser parameters were used successfully for 49 resistant

    Melatonin, an endogenously produced hormone, might potentially limit the ischemia reperfusion injury and improve the efficacy of mechanical reperfusion with primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI). This study was aimed to evaluate whether the treatment effect of melatonin therapy in patients with STEMI is influenced by the time to administration. We performed a post hoc analysis of the Melatonin Adjunct in the Acute Myocardial Infarction Treated With Angioplasty trial (NCT00640094), which randomized STEMI patients to melatonin (intravenous and intracoronary bolus) or placebo during pPCI. Randomized patients were divided into tertiles according to symptoms onset to balloon time: first tertile (136 ± 23 minutes), second tertile (196 ± 19 minutes), and third tertile (249 ± 41 minutes). Magnetic resonance imaging was performed within 1 week after pPCI. A total of 146 patients presenting with STEMI within 360 minutes of chest pain onset were randomly allocated to intravenous and intracoronary melatonin or placebo during pPCI. In the first tertile, the infarct size was significantly smaller in the melatonin-treated subjects compared with placebo (14.6 ± 14.2 vs 24.9 ± 9.0%; p = 0.003). Contrariwise, treatment with melatonin was associated with a larger infarct size in the group of patients included in the third tertile (20.5 ± 8.7% vs 11.2 ± 5.2%; p = 0.001), resulting in a significant interaction (p = 0.001). In conclusion, the administration of melatonin in patients with STEMI who presented early after symptom onset was associated with a significant reduction in the infarct size after pPCI.

    Evaluation of patients with multivessel coronary disease for percutaneous transluminal coronary angioplasty raises the question: Is incomplete revascularization an acceptable procedure in these patients, or does complete revascularization need to be performed, as in coronary artery bypass grafting? To provide an answer the present study utilized exercise thallium imaging as a guide to the performance of angioplasty in 85 patients with multivessel coronary disease. Preangioplasty exercise thallium imaging helped to identify the primary stenosis (culprit lesion) in 93% of patients. Two weeks to 1 month after dilation of this lesion, repeat thallium imaging identified two patient groups: Group 1, 47 patients with no evidence of ischemia in a second vascular distribution and Group 2, 38 patients with evidence of further angioplasty. In Group 2 47% of patients had angioplasty of a second vessel and 79% required multivessel angioplasty at 1 year follow-up. In contrast, only six Group 1 patients (13%) required angioplasty of a second vessel at 1 year. Thus, incomplete revascularization may be an acceptable approach in many patients with multivessel coronary disease. Stress thallium-201 imaging may be a useful technique in the evaluation and management of these patients

    To analyse the actual contribution of digital angiography in the angioplasty setting and to assess its utility to optimize angioplasty results. One hundred patients with single vessel coronary artery disease, without previous angioplasty or coronary artery bypass graft surgery, who underwent angioplasty from January to December 1990. Views were obtained in standard films and also in digitized angiograms. The latter was acquired before angioplasty in order to precisely quantify the stenosis and also to measure the reference diameter of the artery that was used and to choose the balloon catheter for each case. New acquisitions were done during and after the end of the procedure to confirm the residual stenosis and to measure the final diameter. The mean stenosis pre angioplasty was 78.2%, the mean reference diameter 2.8 mm and the mean diameter at the stenotic site 0.8 mm. The balloon artery relation was 0.9:1. After angioplasty the residual stenosis was 13.6% and the dilated segment had a final diameter of 2.6 mm. There were no complications in any patient. Digital angiography is a useful method for laboratories devoted to coronary interventions for it allows confirmation of the severity of the stenosis, optimizes the balloon/artery relation, monitors partial results and measures the residual stenosis as well as the final diameter.

    Prophylactic implantation of a Hemopump (Johnson and Johnson, Skillman, NJ) has been evaluated in nine patients selected for high risk coronary angioplasty. They were unstable patients, refractory to maximal pharmacology, with indications for revascularization, but contraindications for surgery such as low ejection fraction and lack of material for bypass. In all, the target lesion was located on the last patent vessel. The pump was inserted under local anesthesia, without any graft. A specially designed occluder permitted avoidance of retrograde bleeding during implantation. The bypass flow ranged from 2.5 to 3.2 L/min, and permitted a rise in cardiac index from 2.05 to 2.55 L/min/m2, with a drop in capillary wedge pressure from 13 (7-18) to 10 (7-13) mmHg. During balloon inflation, no electrocardiographic changes were observed, because only minor ventricular arrhythmias occurred. No significant hemolysis was seen (plasma free hemoglobin less than 10 mg/dl in all) after 2 hr of pumping. The only limitation of the technique appears to be difficulty at the time of implantation from narrow, stenosed, or tortuous iliofemoral arteries (3 patients). This experience strongly supports the benefit of temporary left ventricular Hemopump support in high-risk situations and clearly shows the need for a smaller pump.

    Forty one patients (pts) underwent semiupright exercise gated radionuclide ventriculography (EGRNV) before, within 3 d after single vessel transluminal coronary angioplasty (TCA), and 4 to 12 mos later, at which time follow-up cardiac catheterization was also performed. Prior to TCA 76% of pts had abnormal EGRNV, as defined by a failure to increase ejection fraction (EF) by 5 points or the development of a new regional wall motion abnormality. Stenosis was reduced from 90 +- 7% to 18 +- 17%. Early after TCA, exercise duration and maximum double product increased (p's 20% but <50%; Group III (n=8): ≥ 50%] Pts with abnormal EGRNV early after TCA were demonstrated to have a greater percent increase in stenosis at late follow-up than pts with normal EGRNV (41 +- 30% vs 19 +- 25%, p<.001). Early after TCA EGRNV was abnormal in 5% of Group I pts vs 75% in Group III (p<.01), and EF increased to a greater degree during exercise in Group I pts (+11.3 +- 7.5 vs +3.5 +- 6.5 points, p<.01). At 4-12 mos EGRNV was abnormal in 27% of Group I vs 88% of Group III (p<.01), and during exercise EF increased in Group I pts (+11.8 +- 7.8 points) but decreased in Group III (-1.9 +- 8.7 points) (p<.0005). The accuracy of abnormal EGRNV in predicting ≥ 50% restenosis was 73% early post-TCA and 77% at 4-12 mos. The authors conclude that EGRNV is a valuable test to verify the success of TCA and to detect subsequent restenosis

    To determine the frequency of myocardial damage in elective, successful, single vessel percutaneous coronary angioplasty by assessing myocardial band (MB), creatinine kinase levels and to find out the association of common modifiable risk factors with myocardial damage in patients undergoing single vessel coronary angioplasty. Fifty patients undergoing elective and successful single vessel percutaneous coronary angioplasty were evaluated with creatinine kinase and creatinine kinase MB levels before and after 8 hours and 1st day following coronary angioplasty. Studied variables included the length of stent deployed, maximum deployment pressure and total balloon inflation time, apart from hypertension, cholesterol level, smoking and diabetes mellitus. Out of 50 patients, 9 had raised creatinine kinase at 8 hours (18%) and 10 had raised creatinine kinase (20%) on 1st day following coronary angioplasty, 7 (14%) patients and 8 (16%) patients had raised creatinine kinase MB levels at 8 hours and 1st day following coronary angioplasty respectively. The rise of either was equal to or more than 3 times the normal limits. Modifiable risk factors, significantly associated with myocardial damage, were diabetes mellitus (p=0.006) and LDL levels (p=0.009) in patients undergoing single vessel coronary angioplasty. Successful elective, uncomplicated, single vessel coronary angioplasty resulted in some myocardial damage evident by mild rise in cardiac enzymes but rise of creatinine kinase MB above 3 times of normal, which signifies percutaneous coronary angioplasty-related myocardial infarction, was not seen. There was a significant association between diabetes mellitus, LDL levels and myocardial damage in patients undergoing coronary angioplasty but no significant association was found between hypertension, smoking and myocardial damage.

    Ching-Hui Huang

    Full Text Available OBJECTIVES: Oxidized low-density lipoproteins (oxLDL and oxidized low-density lipoprotein autoantibodies (OLAB have been detected in human plasma and atherosclerotic lesions. OLAB appear to play a role in the clearance of oxLDL from circulation. Higher levels of OLAB appear to be associated with a reduced risk of a wide range of cardiovascular diseases. We investigated the prognostic value of plasma oxLDL and OLAB in patients undergoing primary coronary balloon angioplasty for acute ST-elevation myocardial infarction (STEMI. METHODS: Plasma oxLDL and OLAB concentrations were measured in 56 patients with acute STEMI before primary angioplasty, and then 3 days, 7 days and 1 month after the acute event. Follow-up angiography was repeated 6 months later to detect the presence of restensosis (defined as >50% luminal diameter stenosis. The thrombolysis in myocardial infarction (TIMI risk score was calculated to determine the relationship between OLAB/oxLDL ratio and TIMI risk scores. RESULTS: Of the 56 patients, 18 (31% had angiographic evidence of restenosis. Plasma OLAB concentrations were significantly lower in the restenosis group before angioplasty (181±114 vs. 335±257 U/L, p = 0.003, and at day 3 (155±92 vs. 277±185 U/L, p<0.001 and day 7 (177±110 vs. 352±279 U/L, p<0.001 after the acute event. There was no difference in oxLDL concentration between the two groups. The ratio of OLAB/oxLDL positively correlated with TIMI risk scores before angioplasty (p for trend analysis, p = 0.004, at day 3 (p = 0.008 and day 7 (p<0.001 after STEMI. SIGNIFICANCE: A relative deficit of OLAB, and hence likely impaired clearance of oxLDL, is associated with the risk of arterial restenosis after primary angioplasty for acute STEMI.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    A new circulatory system, "physiologic anteroperfusion system", has been developed and tested in 6 patients with significant proximal coronary artery stenosis. Prolonged and safe balloon inflation was possible without any ischemic signs. The system consists of an electronic cardiac synchroperfusor which, by activating a pulsatile unit, permits increased diastolic anteroperfusion of autologous blood under physiologic pressure through low-profile standard angioplasty catheters. This study reports the results obtained in 6 patients during proximal prolonged percutaneous transluminal coronary angioplasty. Four men and two women suffering from severe exertional angina pectoris, with normal resting left ventricular function, no collaterals and excellent apical two-dimensional four-chamber echocardiographic views were studied. After a 90 +/- 10 seconds of control occlusion under continuous monitoring of hemodynamics, electrocardiograms (3 to 4 leads), two-dimensional echo and chest pain grading, a second balloon inflation protected by the physiologic anteroperfusion system at a flow rate of 44 +/- 12 ml/min was performed for fifteen minutes. The ischemic signs present in the myocardium depending on the occluded artery were totally abolished during prolonged inflation protected by physiologic anteroperfusion system. All the patients were successfully dilated and were discharged from hospital the following morning without cardiac enzyme elevation or signs of central or peripheral hemolysis. Conclusion, in 6 patients with severe proximal coronary artery stenosis, safe prolonged proximal angioplasty without signs of ischemia was performed using a new simple physiologic anteroperfusion system, which allows active diastolic flow-pressure controlled autologous arterial blood perfusion, through standard low profile catheters.

    To assess the results of transluminal coronary angioplasty 48 patients with coronary heart disease were investigated at rest and during exercise with the ECG (46 patients), thallium-201 myocardial scintigraphy (26 patients), and equilibrium radionuclide ventriculography (38 patients). Exercise stress test was quantified by means of an ischemia score, myocardial scintigraphy by an vitality index and by corresponding redistribution factors, and radionuclide ventriculography by ejection fraction and maximum systolic volume change as a fraction of enddiastolic volume. This, the results show, that in selected cases, TCA can achieve improved left ventricular function and perfusion comparable to that of aortocoronary bypass surgery. (orig./MG) [de

    Conduction disorders in patients with ST-segment elevation myocardial infarction (STEMI) are associated with high mortality. Previous studies have analyzed the implications of AVB in acute coronary syndrome treated with fibrinolysis. However, the implications of AVB in patients with STEMI treated with primary angioplasty have not been sufficiently studied. 913 patients with STEMI treated with primary angioplasty. All clinical, electrocardiographic and angiographic variables were collected. AVB was documented in 115 patients (12.6%). On admission, AVB was present in 70 (7.7%), and persistent at hospital discharge in 36 (3.9 %). Within these, first-degree AVB was present in 29 (3.2%), second-degree in 27 (3%) and third-degree in 73 (8%). AVB was more frequent in women, elderly, hypertensive, diabetic, with worse functional class (Killip class > 2) and with higher incidence at inferior infarctions (P < 0.05). AVB in general and, more specifically, third-degree AVB was associated with a higher mortality (20.5% versus 5.7%; P < 0.001), re-infarction (8.2% versus 3.6%; P = 0.06) and a greater incidence of cardiogenic shock (33.3% versus 14%; P < 0.001). Interestingly, these events were more common in patients who had persistent AVB at hospital discharge than in those with transitory AVB or present at admission AVB. In the multivariate analysis, persistent AVB at hospital discharge proved to be an independent predictor of cardiovascular events (death and recurrent infarction), not the rest of AVB. AVB in patients who underwent primary angioplasty is associated with a worse prognosis while is in-hospital. This risk is particularly high in patients who had persistent AVB at hospital discharge.

    The purpose of this study was twofold: (1) to assess the value and limits of stress thallium myocardial imaging in the diagnosis of reclosure after percutaneous transluminal coronary angioplasty (PTCA) and (2) to determine how myocardial viability, as determined on thallium imaging, influenced the therapeutic option. In study 1, 117 segments, which were treated with PTCA, were examined. Of 52 segments that showed thallium defects, 27 were treated with repeated PTCA. Of the other 25 segments, 12 were found to be reclosed. On the other hand, 65 other segments showed redistribution on thallium imaging, and 60 of these had no reclosure. The remaining 5 segments that were reclosed reflected no evidence of myocardial viability. These findings suggest that coronary arteriography may omitted when redistribution is seen on stress thallium imaging after PTCA. The population in Study 2 included 39 patients who were diagnosed as having myocardial necrosis on thallium imaging. In 22 of these patients, thallium findings ruled out coronary revascularization. One other patient did not undergo coronary revascularization because of technical problems. Thus, the remaining 16 patients were treated with coronary revascularization combined with bypass surgery for necrotic zones (n=10) or with PTCA for preserved collateral circulation (n=6). For necrotic zones evidenced on thallium imaging, factors other than necrosis were considered in determining coronary revascularization. (N.K.)

    Aspirin use is necessary after a coronary angioplasty. It should not be used in patients with a history of hypersensitivity. However, rapid desensitization protocols have been reported to allow its use in such patients. One of these protocols consists in the administration of progressive doses of aspirin, from 1 to 100 mg in a period of 5.5 hours, in a controlled environment. We report four male patients aged 45,49, 59 and 73 years with a history of aspirin hypersensitivity, who were subjected to a coronary angioplasty. In all, the rapid aspirin desensitization protocol was successfully applied, allowing the use of the drug after the intervention without problems.

    Coronary artery diseases and therapies such as coronary angioplasty would lead to changes in the quality of life in patients. The aim of this study was to determine the effects of collaborative care model on the quality of life in patients after coronary angioplasty. This randomized controlled clinical trial was conducted in Isfahan, Iran during 2015. In this study, 50 samples were selected by simple sampling and randomly allocated into two equal groups of intervention and control. Collaborative care model was performed in the intervention group for 3 months. Data were collected using quality of life (SF-36) questionnaire which includes 36 questions on physical and psychological dimensions and was completed before and one month after the intervention in both groups. Data were analyzed using descriptive and analytical statistics and by independent t- test, paired t test, Chi square and Mann-Whitney tests through SPSS 18. After the intervention, the mean score of quality of life in the intervention group was significantly higher than the control group (Pquality of life and its dimensions in patients undergoing coronary angioplasty 3 months after the intervention (Pmodel had better scores of quality of life in all the physical, mental and social dimensions than the control group. Therefore, using this model for taking care of patients after coronary angioplasty is recommended. Trial Registration Number: IRCT2015120120912N4.

    Full Text Available The acute coronary syndrome is a major cause of hospitalization and high mortality rates. For many there have been ongoing debates years over the treatment method choice and various diagnostic methods. The purpose of the research is to investigate the diagnostic capabilities of emergency coronary angiography and efficacy of transluminal balloon angioplasty with stenting for acute coronary syndrome with lifting and without ST elevation. Results In patients with ACS with ST-segment elevation myocardial contractility was better after thrombolytic therapy, which is appropriate over the first 2 hours of the onset of anginal pain. However, in the group of the patients with ACS with ST-segment elevation violations of local contractility was more common than in the group of patients with ACS without ST-segment elevation. In both groups of patients with ACS the risk of unfavorable outcome did not depend on the number of affected vessels, but on a variant of the syndrome (elevation or without ST elevation. In patients with ACS with ST-segment elevation was significantly more frequently identified hemodynamically significant stenosis of the arteries. In ACS without ST-segment elevation no statistically significant difference in myocardial contractility and risk of unfavorable outcome on the scale of GRACE in groups with single and biarterial coronary disease not obtained. In the case of significant stenoses diagnosed through emergency coronary angiography, emergency balloon angioplasty with stenting is indicated. When there is technical impossibility of angioplasty (excessive tortuosity, occlusion, stenosis of the left main coronary artery, etc., it is advisable to perform emergency bypass surgery. Discussion and Conclusions The analysis of the treatment results it revealed that timely percutaneous transluminal coronary angioplasty with stenting in combination with thrombolytic therapy has contributed significantly to improving not only contractility, but

    Full text: Objective: To survey and assess radiation dose to patients from coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) in Beijing Xuanwu Hospital of Capital University of Medical Sciences. Methods: The dose-area product (DAP) values to the patient and cumulative dose (CD) were recorded from 84 coronary angiographies and 51 percutaneous transluminal coronary angioplasty. A Monte-Carlo based program PCXMC was used to calculate the effective dose from DAP values for each patient. Organ doses were also measured by thermoluminescent dosimeters (TLD) using a human-shaped phantom to compare the calculated organ dose from DAP. Results: The difference between the organ doses measured by TLDs and those from PCXMC software (P>0.05) were tolerable. The DAP value ranged from 7611∼60538 mGy·cm 2 for CA and 16423∼161973 mGy·cm 2 for PTCA. The effective dose for all procedures was determined to be in the range of 1.1∼6.9 mSv for CA and 2.3∼20.1 mSv for PTCA. CD ranged from 120.0 to 1016.0 mGy for CA and 287 to 2883 mGy for PTCA. Conversion factors between effective dose and DAP were 0.114∼0.139 mSv·Gy - 1·cm -2 for CA and 0.124∼0.142 mSv·Gy -1 ·cm -2 for PTCA; Conversion factors between organ dose and CD were derived for CA and PTCA, respectively. Conclusions: DAP and CD can be used as the dose indicator to calculate the organ dose and effective dose of patient based on Monte Carlo simulation. Using this method can provide important information of patient absorbed dose and enhance the radiation protection of patient in interventional radiology procedures. (author)

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

    Full Text Available Purpose. Coronary-subclavian steal syndrome (CSSS is defined as a reversal of flow in a previously constructed internal mammary artery (IMA coronary conduit, producing myocardial ischemia. We present a case of CSSS which could not be ameliorated with endovascular therapy and necessitated a subclavian-subclavian bypass. Case Report. 80-year-old Caucasian male with history of CABG presented with syncope. He had absent left-sided radial pulse with blood pressure being 60/40 on left arm and 130/80 on the right. He underwent cardiac catheterization for NSTEMI which showed patent left internal mammary artery graft to left anterior descending coronary artery with retrograde flow, and diagnosis of coronary subclavian steal syndrome was made. Complete occlusion of proximal left subclavian artery was identified. Percutaneous angioplasty failed because of calcified plaque causing 100% occlusion. Carotid doppler showed bilateral carotid artery disease. He finally underwent subclavian-subclavian bypass which resolved his condition. Conclusion. Subclavian-subclavian bypass is a successful alternative to carotid-subclavian bypass for management of CSSS especially with concomitant critical carotid artery atherosclerotic disease.

    A 58-year-old man underwent percutaneous transluminal coronary angioplasties in June 1992 and May 1993. Approximately 3 weeks after the last procedure, a cutaneous lesion developed into an ulcer over the right scapular region. The ulcer failed to heal with conservative treatment; therefore, surgical excision was performed. The localization and the course of the development indicated injury caused by radiation, and this was confirmed by the histologic examination. To avoid such injury in interventional procedures with long fluoroscopic time, several percautions should be taken. These include continuous surveillance of the X-ray dosage, the use of different projections to avoid exposure to one skin area throughout the whole procedure, keeping the irradiated area as small as possible, and good planning of the procedure.

    Diabetes mellitus is one of the major risk factors for coronary artery disease. The aim of this study was to evaluate in-hospital mortality and during follow-up of diabetic patients with acute myocardial infarction treated with primary angioplasty and to determine its predictors. Eight hundred and sixty six patients were retrospectively enrolled from January 1993 to December 2013. A hundred patients with a diagnosis of diabetes were evaluated. The median follow-up was 121 months in 90% of the population. Of the 100 diabetic patients included (11.56%) 86% were male and 50% older than 70 years. Overall, 76% presented with a Killip-Kimball grade of 1 at admission and 16% presented with a Killip-Kimball 4. The most frequent location of myocardial infarction was anterior and 65% had 2 or more coronary vessel disease. In-hospital mortality was 15%. The only independent variable significantly associated was the Killip-Kimball at admission. Mortality during follow up was 35% and its independent predictors were: age, Killip-Kimball at admission and use of angiotensin-converting enzyme inhibitors Interestingly, in the non-diabetic group, Killip-kimball at admission failed to predict long-term mortality This group of diabetic patients was older, and with a higher prevalence of 2 or more vessel disease. Cardiogenic shock on admission was the only independent predictor of in-hospital death and along with age and angiotensin-converting enzyme inhibitor use, an independent predictor of mortality during long term follow-up.

    Full Text Available Coronary artery stent infection has been reported with both bare metal stent and drug eluting stent and can present as mycotic coronary artery aneurysm, pseudoaneurysm, myocardial abscess, pericarditis or exudative effusion. Infection at the site of coronary stent implantation is rare and is believed to result typically from either direct stent contamination at the time of delivery or transient bacteraemia from access site. Introduction of drug-eluting stent (DES has led to a marked reduction in the problem of in-stent restenosis across all patient subsets and lesions complexities. Recently, several case reports of pseudoaneurysm formation after DES implantation have been reported in the literature. We describe the successful surgical management of giant mycotic pseudoaneurysm of left anterior descending artery (LAD presenting as fever of unknown origin. This report illustrates the importance of early detection and prompt management of these rare coronary pseudoaneurysms, which is a highly lethal condition.

    More aggressive therapy has been suggested for patients who have a non-Q wave myocardial infarction (MI) because of the frequency of subsequent unstable angina, recurrent MI, and high mortality rate compared to patients with Q wave MI. The present study was undertaken to investigate the effect of coronary angioplasty on regional myocardial function of the infarct zone in patients with angina early after a non-Q wave MI. The study population consisted of 36 patients undergoing successful coronary angioplasty within 30 days of a non-Q wave MI, in whom sequential left ventricular angiograms of adequate quality were obtained before the initial procedure and at follow-up angiography. The global ejection fraction increased significantly from 60 +/- 9% to 67 +/- 6% (p = 0.0003). This significant increase in the global ejection fraction was primarily due to a significant improvement in the regional myocardial function of the infarct zone. The results of the present study show not only that ischemic attacks early after a non-Q wave MI may lead to prolonged regional myocardial dysfunction but more important that this depressed myocardium has the potential to achieve normal contraction after successful coronary angioplasty

    Full Text Available Introduction : Balloon pulmonary angioplasty (BPA is a new emerging catheter-based alternative treatment option for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH. Aim : To show that all elderly CTEPH patients referred for BPA are at higher risk of obstructive coronary artery disease and that, in daily practice, they should undergo invasive coronary angiography. Material and methods : Eleven patients at the age of at least 65 years (6 males, 5 females, 77.2 ±5.9 years with confirmed non-operable type II or type III CTEPH, considered for BPA, underwent elective coronary angiography. Severe obstructive coronary artery disease (CAD was diagnosed when stenosis of left main coronary artery ≥ 50% or stenosis of ≥ 70% of epicardial arteries was angiographically confirmed. We also screened for CAD consecutive age- and sex-matched 114 PE survivors (52 males, 62 females, 74.8 ±7.2 years with excluded CTEPH. Results : Severe CAD was more frequent in elderly patients with non-operable type II or type III CTEPH candidates for BPA than in elderly acute PE survivors with excluded CTEPH (54.5% vs. 16.7%, p < 0.01, and therefore elderly CTEPH patients referred for BPA were at higher risk of CAD (OR = 5.9, 95% CI: 1.64–21.46, p = 0.007 when compared to elderly survivors after acute PE with excluded CTEPH. Conclusions : All elderly CTEPH patients referred for BPA are at higher risk of severe CAD and should routinely undergo invasive coronary angiography before BPA.

    Statins are the main resource available to reduce LDL-cholesterol levels. Their continuous use decreases cardiovascular morbidity and mortality due to atherosclerosis. The administration of these medications demonstrated to be effective in primary and secondary prevention clinical trials in low and high risk patients. Specialists believe that a possible benefit of hypolipidemic therapy in preventing complications of atherosclerotic diseases is in the reduction of deposition of atherogenic lipoproteins in vulnerable areas of the vasculature. Experimental studies with statins have shown an enormous variety of other effects that could extend the clinical benefit beyond the lipid profile modification itself. Statin-based therapies benefit other important components of the atherothrombotic process: inflammation, oxidation, coagulation, fibrinolysis, endothelial function, vasoreactivity and platelet function. The demonstration of the effects that do not depend on cholesterol lowering or the pleiotropic effects of statins provides the theoretical basis for their potential role as adjunctive therapy in acute coronary syndromes. Retrospective analyses of a variety of studies indicate the potential benefit of statins during acute coronary events. Recent clinical studies have addressed this important issue in prospective controlled trials showing strong evidence for the administration of statins as adjunctive therapy in acute coronary syndromes.

    Acute mesenteric ischaemia is a challenging diagnostic problem with a very high mortality. Traditionally, laparotomy is required for definitive management. We describe a successful case of angioplasty and stenting of the superior mesenteric artery in a surgically unfit patient. We recommend that stenting be considered only in situations where the diagnosis has been made prior to bowel infarction, and if the patient poses a poor operative risk.

    A prospective study comparing the long-term results of balloon angioplasty in patients over 75 years of age with those in a younger patient group is not available. A total of 192 consecutive patients aged > or = 75 years (group I) who underwent a balloon angioplasty were matched with 192 control patients aged 40 to 65 years (group II). The groups were matched for gender, angina pectoris class, left ventricular function, 1-, 2-, and 3-vessel coronary artery disease, and previous myocardial infarction. The mean follow-up was 40.4 months (range 0 to 110). Actuarial analysis (freedom from events) after 5 years yielded the following results for group I versus group II: free from death remained 77.1% versus 97.9% (p = 0.0001), from cardiac death 92.4% versus 97.9% (p = 0.049), and from angina pectoris 54.6% versus 75.1% (p = 0.03). The differences were not significant for those remaining free from myocardial infarction, repeat balloon angioplasty, or coronary artery bypass grafting. When elderly patients with complete revascularization (n = 127) were compared with a matched control group of 127 patients aged 40 to 65 years who underwent complete revascularization, there was only a significant difference in noncardiac death rates. We conclude that patients > 75 years of age have a significant higher cardiac and noncardiac death rate and a higher incidence of angina pectoris after successful balloon angioplasty. However, the incidence of reintervention and myocardial infarction is lower in the elderly. If complete revascularization is achieved in the elderly, then freedom from cardiac death and recurrence of angina pectoris would be comparable to that in younger patients.

    The effect of insulin resistance (IR) on the fatty acid metabolism of myocardium, and therefore on the recovery of left ventricular (LV) wall motion, has not been established in patients with acute myocardial infarction (AMI). A total of consecutive 58 non-diabetic AMI patients who had successfully undergone emergency coronary angioplasty were analyzed retrospectively. They were categorized into 2 groups, normal glucose tolerance (NGT) and impaired glucose tolerance (IGT), based on a 75-g oral glucose tolerance test (OGTT). The parameters of OGTT, myocardial scintigraphy (n=58) (thallium-201 (Tl) and iodine-123-β-methyl-iodophenylpentadecanoic acid (BMIPP)) and left ventriculography (n=24) were compared in the 2 groups after reperfusion (acute phase) and 3-4 weeks after the AMI (chronic phase). The IR, estimated by the serum concentration of insulin at 120 min (IRI 120') of the OGTT and by the HOMA (the homeostasis model assessment) index, was higher in the IGT group than in NGT group. An inverse correlation was found between the recovery of regional LV wall motion in the ischemic lesion and the IRI 120' and HOMA index. Although the recovery of BMIPP uptake from the acute to the chronic phase was higher in the IGT group, it was only correlated with the degree of IRI 120', not with the HOMA. IR accompanied by IGT can negatively influence the recovery of regional LV wall motion. (author)

    To evaluate (i) local coronary and systemic levels of microparticles (MP) in acute coronary syndrome (ACS) and stable angina pectoris (SAP) patients and (ii) their release after plaque disruption with percutaneous coronary intervention (PCI). MP are small vesicles originating from plasma membranes of cells after activation or apoptosis and are implicated in the pathogenesis of atherosclerosis. Neutrophils play a role in plaque destabilization and shed neutrophil-derived MP that have the potential to drive significant proinflammatory and thrombotic downstream effects. Eight ACS and eight SAP patients were included. Coronary sinus (CS) samples pre-intervention (CS1), 45 s following balloon angioplasty (CS2) and at 45 s intervals following stent deployment (CS3, CS4 and CS5), together with peripheral vein samples, pre- and post-PCI were analysed for neutrophil-derived (CD66b+), endothelial-derived (CD144+), platelet-derived (CD41a+), monocyte-derived (CD14+) and apoptotic (Annexin V+) MP. ELISA for interleukin (IL)-6, myeloperoxidase (MPO) and P-selectin was also performed. CD66b+ MP levels were similar in both groups pre-intervention. Post-PCI, CS levels rose significantly in ACS but not SAP patients (ACS area under the curve (AUC): 549 ± 83, SAP AUC: 24 ± 29, Pderived MP release post-PCI occurs in ACS compared with stable patients, likely to be reflective of plaque MP content in vulnerable lesions. © 2017 The Author(s).

    The diagnostic value of exercise electrocardiography using 14 leads and thallium-201 scintigraphy were evaluated in 54 of 70 patients who underwent percutaneous transluminal coronary angioplasty (PTCA), both in the initial assessment and serial follow-up of patients after PTCA. Of the 45 patients who had successful PTCA, 36 had complete noninvasive studies performed before and 1 month after PTCA. The use of clinical symptoms in conjunction with the physiologic data, ECG and myocardial scintigram acquired during exercise provide important short-term data on the angiographic evolution of PTCA results. The noninvasive tests may be useful in determining guidelines for repeat angiography in patients who have had PTCA

    Full Text Available Background: Contrast induced nephropathy is a potential cause of mortality and morbidity in patients undergoing angiography–angioplasty. Except for hydrating and probably low – isoosmolar contrast agents in high risk groups, other modalities have not provided benefit. We investigated preventive effects of captopril for contrast induced nephropathy during angiography–angioplasty. Methods: In a double blind placebo controlled clinical trial, 88 patients were randomized to two groups: 42 patients received captopril (12.5 mg every 8 hours from 2 hours before the procedure until 48 hours thereafter, and 46 patients received placebo in the same manner. Serum creatinine was measured before and 48 hours after angioplasty. The data were analyzed by SPSS software, using unpaired student t-test for comparing mean creatinine rise in both groups and paired student t-test for the changes in serum creatinine in each group. Results: The mean creatinine rise in captopril group (0.214 mg/dl and placebo group (0.226 mg/dl were not significantly different. The incidence of acute renal failure (creatinine rise more than 0.5 mg/dl in the captopril (11.9 % and placebo group (10.8 % were not significantly different. Conclusion: Captopril does not effectively prevent contrast nephropathy, but it is not harmful for renal function and can be administered safely during angiography – angioplasty in patients with normal renal function. However, the effect of captopril in patients with high- risk characteristics remains to be clarified. Of note, we found a trend for less creatinine rise in diabetics who received captopril during the procedure in comparison to diabetics who received placebo.

    To evaluate the efficacy of percutaneous transluminal angioplasty (PTCA), as a revascularization procedure in patients with symptomatic coronary artery disease in the 8th and 9th decades of life. Four hundred and fifty-two elderly patients (mean age 74.7 years) underwent balloon dilation, between April 1982 and June 1990, at the Institute "Dante Pazzanese" of Cardiology. There were 70.4% male, 34.9% with high blood pressure, 18.8% smoked and 10.8% with diabetes. Ninety-four patients (20.7%) had previous myocardial infarction and systemic disorders were diagnosed in 14% (renal failure 5.1%, respiratory insufficiency 3.1%, rheumatic and bone disorders 1.1%, malignancy 4.2%, haematologic disorders 0.4%). One hundred and seventy-three (38.3%) had multivessel coronary artery disease whereas 84 (18.5%) had moderate to severe dysfunction of the left ventricle. PTCA was done according to the method described by Grüntzig, with the use of a "over the wire" (LPS, USCI, Mini Profile USCI, ACX ACS) balloon or a "on the wire" (Probe USCI, Axcel ACS) System. Primary success was achieved in 406 (89.5%) patients where PTCA was done to dilate one vessel in 412, two vessels in 38 and three vessels in 2, accomplishing 494 dilated vessels. Major complications occurred in 14 (3.1%) patients, due to occlusion of the treated coronary artery. Emergency by-pass surgery was necessary in 5 (1.1%) patients, while 8 patients involved to acute myocardial infarction (1.8%), and 5 (1.1%) died. At the end of the late follow-up (mean 24.5 months) of 349 elderly patients (86% of the 406 successful dilated) 246 (70.5%) were asymptomatic, chest pain had recurred in 101 (28.9%) and 2 (0.6%) had myocardial infarction. Twenty-eight patients died during the follow-up, 14 of them (4.0%) due to cardiac causes. Late restenosis developed in 66 patients and 22 had progression of coronary atherosclerosis. Forty patients underwent a late PTCA, and 33 others underwent a late bypass surgery. PTCA in patients in

    Progressive ventricular dilatation is an important prognostic factor in patients with acute myocardial infarction. We evaluated clinical, angiographic, echocardiographic and thallium-201 single-photon emission tomography (SPET) imaging variables predictive of the change in left ventricular volume during a 7-month follow-up period after primary angioplasty in patients with acute myocardial infarction. Thirty-six patients with first acute myocardial infarction treated with primary angioplasty within 12 h of onset underwent {sup 201}Tl SPET imaging (5.8{+-}2.1 days after angioplasty). Changes in left ventricular volume were assessed over the 7-month period. The left ventricle dilated significantly after angioplasty (P<0.001). Multivariate analysis revealed that the number of segments with {sup 201}Tl uptake <40% of peak activity was a single independent predictor of increase in end-diastolic volume index between 1 week and 7 months (R{sup 2}=0.41, P< 0.001). The presence of two or more segments with {sup 201}Tl uptake <40% predicted an increase in end-diastolic volume index of {>=}6 ml/m{sup 2} with positive and negative predictive values of 85% (17/20) and 75% (12/16), respectively. It is concluded that, following primary angioplasty in patients with acute myocardial infarction, the extent of myocardial infarction assessed by {sup 201}Tl SPET can identify those who will develop ventricular dilatation during the subsequent 7 months.

    Type VIII collagen is upregulated after vessel injury, and this collagen has been implicated in both smooth muscle cell migration and angiogenesis. This study examines the temporal and spatial pattern of expression of type VIII collagen in porcine coronary vessels at specific time points after balloon angioplasty. In situ hybridization studies demonstrated that collagen VIII messenger ribonucleic acid (mRNA) was markedly elevated in the neoadventitia at 3 days post-angioplasty. By 14 days, elevated collagen VIII message was seen mainly in the neointima and this expression decreased to background levels by 90 days. The distribution of collagen VIII protein, detected using immunohistochemistry, was similar but the up-regulation lagged behind the mRNA increase by a few days. Pre-treatment of sections with pepsin highlighted variations in the organization and appearance of extracellular collagen VIII containing structures in both injured and normal vessels. New vessel formation was evident in the neoadventitia after 3 days, but there was no colocalization of type VIII collagen immunostaining with that of von Willebrand factor (a marker of endothelial cells) in the neoadventitia. These data show that up-regulation of collagen VIII in the neoadventitia is an important early marker of the coronary arterial response to injury, and is not associated with new vessel formation.

    The major aim of this review was to ascertain whether effective evidence-based treatments for acute coronary syndromes (ACS) are underutilized in women in various geographic areas compared with men. The focus of our review was the relative use of effective treatments in patients with coronary angiographic evidence of obstructive coronary disease, defined as a lumen stenosis >50% of the adjacent non-diseased arterial diameter. We searched MEDLINE, and the Cochrane Database between January 1998 and May 2008. Only a few of the published clinical registries on ACS provide data on treatments dichotomized by confirmed coronary angiographic disease. Consequently, we also accessed individual patient-level data from 3 established ACS registries: the Finnish TACOS (Tampere Acute COronary Syndrome), the British EMMACE 2 (Evaluation of Methods and Management of Acute Coronary Events) and the Argentine PACS-ITALSIA (Prognosis in Acute Coronary Syndromes and the ITALian hospital Sindrome Isquemico Agudo). Despite presenting with higher risk characteristics and having higher in-hospital and 6 months risk of death, women with ACS and obstructive coronary artery disease were apparently treated less aggressively with secondary preventive drugs than were men, being less likely to receive aspirin, beta-blockers and statins at discharge. Overall, coronary revascularization appears to be performed in a similar proportion of women and men - once angiography has been performed and the coronary anatomy is known. However, substantial geographic variation exists in the relative rate of coronary angiography in men and women. In United Kingdom coronary revascularization tends to be done less frequently in women. Our study, therefore, demonstrates a gender bias in the delivery of secondary drug treatments for ACS, even for patients with documented significant coronary disease.

    Post-marketing surveillance (PMS) may identify rare serious incidents or adverse events due to the long-term use of a medical device, which was not captured in the pre-market process. Percutaneous transluminal coronary angioplasty (PTCA) is a non-surgical procedure that uses a balloon-tipped catheter to enlarge a narrowed artery. In 2011, 1,942 adverse event reports related to the use of PTCA catheters were submitted to the FDA by the manufacturers, an increase from the 883 reported in 2008. The primary research objective is to conduct a systematic review of the published and grey literature published between 2007 and 2012 for the frequency of incidents, adverse events and malfunctions associated with the use of PTCA catheters in patients with coronary artery disease (CAD). Grey literature has not been commercially published. We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and PubMed for medical literature on PMS for PTCA catheters in patients with CAD published between January 2007 and July 2012. We also searched the grey literature. This review included 11 studies. The in-hospital adverse events reported were individual cases of myocardial infarction and hematoma. In studies of patients with coronary perforation, more patients with balloon angioplasty were identified compared with patients who required stenting. Our systematic review illustrates that the volume and quality of PMS studies associated with the use of PTCA catheters in patients with CAD are low in the published and grey literature, and may not be useful sources of information for decisions on safety. In most studies, the objectives were not to monitor the long-term safety of the use of PTCA catheters in clinical practice. Future studies can explore the strengths and limitations of PMS databases administered by regulatory authorities.

    The use of coronary balloons in the cerebral vasculature is limited due to their poor trackability and increased risk of vessel injury. We report our experience using more compliant elastomer balloons for thrombus resistant to intraarterial (IA) pharmacological and mechanical thrombolysis in acute stroke. We retrospectively analyzed 12 consecutive patients with an occluded intracranial artery treated with angioplasty using a low-pressure elastomer balloon. Angiograms were graded according to the Thrombolysis in Cerebral Infarction (TICI) and Qureshi grading systems. Outcomes were categorized as independent (modified Rankin scale, mRS, score ≤2), dependent (mRS score 3-5), or dead (mRS score 6). Included in the study were 12 patients (mean age 66±17 years, range 31-88 years; mean baseline National Institutes of Health stroke scale score 17±3, range 12-23). The occlusion sites were: internal carotid artery (ICA) terminus (five patients, including two concomitant cervical ICA occlusions), M1 segment (two patients), and basilar artery (two patients). Pharmacological treatment included intravenous (IV) t-PA only (two patients), IA urokinase only (nine patients), both IV t-PA and IA urokinase (one patient), and IV and/or IA eptifibatide (eight patients). Mean time to treatment was 5.9±3.9 h (anterior circulation) and 11.0±7.2 h (posterior circulation). Overall recanalization rate (TICI grade 2/3) was 91.6%. Procedure-related morbidity occurred in one patient (distal posterior inferior cerebellar artery embolus). There were no symptomatic hemorrhages. Outcomes at 90 days were independent (five patients), dependent (three patients) and dead (four patients, all due to progression of stroke with withdrawal of care). Angioplasty of acutely occluded intracranial arteries with low-pressure elastomer balloons results in high recanalization rates with an acceptable degree of safety. Prior use of thrombolytics may increase the chances of recanalization, and glycoprotein IIb

    Hyperglycaemia in patients with Acute Coronary Syndrome (ACS)is common, and is an independent predictor of mortality and morbidity in patients both with and without diabetes mellitus. Hyperglycaemia may be a marker of pre-existing diabetes or glucose intolerance or may also represent a transient stress response mediated through the autonomic nervous system with release of adrenal corticosteroids and catecholamines. Several evidences suggest that an intensive control of hyperglycaemia results in a significant improvement of the adverse outcomes in the short and long term. In fact, an intensive metabolic treatment can counteract the negative effects of hyperglycaemia. However, the main difficulty to intensive glucose control in patients with ACS remains hypoglycaemia that is associated with an increased risk of mortality and myocardial re-infarction. No definitive data are available about the beneficial effects of insulin intensive treatment. Therefore, randomized multicenter clinical trials will be needed to definitively establish whether intensive glucose control will reduce the associated increased mortality rate and higher rates of complications in hospitalized ACS patients with hyperglycaemia.

    Full Text Available Cardiac tumors can be primary or metastatic, the latter being more frequent and usually of pulmonary or hematologic origin. These patients’ clinical signs are non-specific and the electrocardiogram (ECG can assume many patterns, among which, ST-segment elevation. Nevertheless, associated occlusion of the coronary arteries is rare in these situations.We present a 79-year-old woman with a history of pulmonary neoplasia who was admitted to the emergency department due to atypical chest pain, cough and worsening dyspnea in the previous 3 days. The ECG revealed an ST-segment elevation in the anterolateral and inferolateral leads, despite normal blood work, namely normal troponin. Due to the disparity between the patient’s symptoms and the ECG findings, a decision was made not to proceed to primary angioplasty, but to further investigate with echocardiography, which revealed a mass localized in the anterolateral and inferolateral left ventricle walls, confirmed by computed tomography. The patient was admitted in the medical ward for symptomatic management. Her clinical condition gradually deteriorated due to the disease’s natural evolution and she died two weeks later.This case highlights the importance to keep in mind differential diagnoses to acute coronary syndromes, when a ST-segment elevation is encountered on an ECG.

    Coronary flow reserve (CFR) in the non-infarcted myocardium is often impaired following acute myocardial infarction (AMI). However, the clinical significance of CFR in the non-infarcted myocardium is not fully understood. The objective of the present study was to assess whether a relationship exists between CFR and left ventricular remodeling following AMI. We enrolled 18 consecutive patients undergoing coronary intervention. Heart function was analyzed using real-time myocardial contrast echocardiography at one week and six months after coronary angioplasty. Ten subjects were enrolled as the control group and were examined using the same method at the same time to assess CFR. Cardiac troponin I (cTnI) levels were routinely analyzed to estimate peak concentration. CFR was 1.55±0.11 in the infarcted zone and 2.05±0.31 in the remote zone (p2.05). The levels of cTnI were higher in Group I compared to Group II on admission (36.40 vs. 21.38, p<0.05). Furthermore, left ventricular end diastolic volume was higher in Group I compared to Group II at six months following coronary angioplasty. Microvascular dysfunction is commonly observed in the remote myocardium. The CFR value accurately predicts adverse ventricular remodeling following AMI.

    Full Text Available We describe the unexpected case of a 70-year-old man, with medical history of ischemic heart disease and surgery for aneurysm of abdominal aorta, who comes to the emergency department complaining of low-back pain without other symptoms or signs of organic failure. After a few hours we see a deterioration of physical conditions with pulmonary oedema, increase of blood pressure, changing in the ECG pattern, and worsening of left ventricular function with progressive increase of biomarkers for myocardial necrosis. So this pain has revealed the premature symptom of an acute coronary syndrome (ACS. After a short time a subsequent cardiac arrest complicates the clinical situation. After resuscitation, the patient undergoes successfully to coronary angiography and performed a percutaneous transluminal coronary angioplasty (PTCA.

    Percutaneous coronary intervention (PCI) has been shown to be the best reperfusion therapy for acute myocardial infarction with ST-elevation (STEMI), but data from registries show differences in patient populations and outcomes between randomized trials and real life. We sought to provide information about the current status of this treatment with a registry collecting data in Lombardy, the most densely populated region in Italy, with widespread availability of cathlabs and a well-established network for the treatment of STEMI. Patient enrollment was performed by 32 hub centres recruiting 3901 STEMI patients who underwent PCI procedures within 12 h of the onset of symptoms, of whom 3317 patients underwent primary PCI, 376 'facilitated' PCI, and 208 rescue PCI in cathlabs located, in 77% of cases, in the same hospital of admission. In-hospital and 30-day total death were 4.4 and 6.6%, respectively. At multivariate analysis independent negative predictors of 30-day mortality were Killip class 3-4, number of involved ECG leads, chronic renal failure and age, whereas positive predictors were ST resolution more than 50% and postprocedural grade 3 thrombolysis in myocardial infarction flow. LombardIMA PCI registry enrolled STEMI patients representing a real-world population treated with PCI. Findings presented in this study may provide a benchmark for similar registries undertaken in other Italian regions and may be helpful to assess future possible developments of care for STEMI patients.

    Full Text Available Aim. To compare effect of percutaneous balloon angioplasty (PCA and a systemic thrombolysis (STL on the central and intracardiac hemodynamics in patients with acute coronary syndrome (ACS with ST segment elevation.Material and methods. 80 patients with ACS with ST segment elevation were included in the study. Patients were split into 2 groups depending on reperfusion strategy. PCA was performed in 55 patients (first group. 25 patients of the second group had STL with Streptokinase, i/v, 1 500 000 units per hour. Echocardiography was performed in all patients at admission and after 3 and 7 days of treatment to evaluate intracardiac hemodynamics.Results. Both reperfusion methods significantly increase of ejection fraction (EF and maximal output speed of left ventricle (LV. Increase of LV EF in patients after PCA was higher than this in patients after STL. PCA improved LV diastolic function; STL did not change this characteristic. After PCA working diagnosis of ACS was transformed to the following final diagnosis: acute myocardial infarction (AMI with Q, AMI without Q and unstable angina in 37,5, 30,4 and 32,1% of patients, respectively. After STL diagnosis of AMI with Q was defined in all patients.Conclusion. PCA in patients with ACS with ST segment elevation results in fast improvement of global systolic and diastolic LV function. Besides, PCA prevents AMI with Q in a half of these patients.

    We report a case of acute coronary syndrome in a patient with suspect Marfan syndrome, 25 days after emergent modified Bentall-De Bono intervention for acute type I peripartum aortic dissection. She was admitted to our intensive care unit because of unstable angina, caused by critical blood flow reduction in a large portion of the myocardium, according to the severity of the symptoms and the electrocardiographic alterations. Coronary angiography showed a sub-occlusive stenosis of the left main coronary artery as a result of the dissection extension to the coronary ostium. Because of the high risk related to heart surgery, the patient was successfully treated by unprotected angioplasty and drug-eluting stent positioning. Short- and mid-term outcomes were favourable. Subsequent tests confirmed the diagnosis of Marfan syndrome. After 2 years of follow-up, the patient remains asymptomatic and in good health. To our knowledge, this is the first report of a successful percutaneous intervention of the left main coronary artery in a patient with Marfan syndrome who had already undergone ascending aortic root and valve replacement by the Bentall-De Bono procedure for acute dissection.

    To prevent contrast induced renal dysfunction a periprocedural prophylactic hydration is applied. Due to dilution it should cause a drop in serum creatinine concentration (SCR). Surprisingly, no reduction in SCR after contrast admission is found in up to 25% of patients as early as 12-18 hours after coronary angiography/angioplasty. This study aims to find a clinical explanation as well as predict circumstances for this phenomenon. Retrospective clinical and laboratory data was used from 341 patients who underwent elective coronary angiography/angioplasty, received a prophylactic hydration, and had serum creatinine concentration measured prior to, and 12-18 hours after invasive procedure with iodine contrast administration. To exclude an improper hydration due to no creatinine decrease, the number of red blood cells was analysed as well as hemoglobin and hematocrit in blood donations collected during the study time points. The resulting lack of serum creatinine reduction could be explained by dehydration (measured by increase in number of RBC, HGB and HCT) only in 13.5% , 10.8%, and 20% of cases, respectively. Any form of abnormal glucose metabolism combined with either baseline serum creatinine concentration creatinine clearance >86.77 mL/min, or GFR by CKD EPI >80.08 mL/min/1.73 m2, or GFR by MDRD >74.48 mL/min/1.73 m2 were the predictors for no creatinine decrease at outcome. Additionally, it was demonstrated that the lack of creatinine decrease was more often observed among those patients whose initial renal function was better than in the subjects with reduction of SCR. This observation requires further prospective investigation on extended group of patients. © 2016 The Author(s) Published by S. Karger AG, Basel.

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    Cardiac function and myocardial perfusion were assessed by exercise-stress thallium SPECT and resting gated blood pool SPECT techniques before and after 47 successful coronary angioplasties. Thallium perfusion was analyzed visually and quantitatively in stress and resting studies. Left ventricular ejection fraction (LVEF) and peak filling rate (PFR) were calculated and regional wall motion was scored by amplitude and phase images in radionuclide planar and tomographic imagings. The thallium redistribution in delayed or resting SPECTs was more sensitive (87%) for detecting myocardial ischemia compared to symptoms (36%) and ECG changes (60%). An exercise capacity, LVEF, PFR, and the scores of perfusion and regional wall motion were improved significantly after coronary angioplasty. Stress thallium and gated blood pool SPECTs showed the improvements of myocardial perfusion in 159 (79%) of 201 segments and regional wall motion in 47 (51%) of 92 segments, respectively. These results suggest that the combined use of stress thallium SPECT, gated blood pool planar and SPECT techniques can contribute not only to the assessment of the efficacy of coronary angioplasty but also to detecting the mismatching of myocardial perfusion and contraction ('myocardial hibernation') in infarct-related myocardial lesions.

    Full Text Available Acute pulmonary embolism is a fatal disease and an often missed diagnosis. There are no specific symptoms or signs. Accurate diagnosis followed by effective therapy can reduce mortality. We report on a 67-year-old man who underwent lumbar laminectomy and developed an acute anterior compressive-like chest pain and jaw numbness rather than dyspnea on the fifth postoperative day. Owing to refractory chest pain with suspicious posterior myocardial infarction or unstable angina on surface electrocardiogram, the patient received emergency coronary catheterization, which demonstrated normal coronary arteries. Further investigation provided a final diagnosis of acute pulmonary embolism. Acute pulmonary embolism with simultaneous recent neuro-surgery was a therapeutic dilemma because of the risk of postoperative hemorrhage threatening neurologic function. After treatment with enoxaparin and close monitoring of his neurologic condition, his symptoms were eliminated. Clinicians must keep in mind a differential diagnosis of pulmonary embolism in a postoperative high-risk patient.

    Full Text Available Controversy exists regarding the diagnostic accuracy, optimal technique, and timing of exercise testing after percutaneous coronary intervention. The objectives of the present study were to analyze variables and the power of exercise testing to predict restenosis or a new lesion, 6 months after the procedure. Eight-four coronary multi-artery diseased patients with preserved ventricular function were studied (66 males, mean age of all patients: 59 ± 10 years. All underwent coronary angiography and exercise testing with the Bruce protocol, before and 6 months after percutaneous coronary intervention. The following parameters were measured: heart rate, blood pressure, rate-pressure product (heart rate x systolic blood pressure, presence of angina, maximal ST-segment depression, and exercise duration. On average, 2.33 lesions/patient were treated and restenosis or progression of disease occurred in 46 (55% patients. Significant increases in systolic blood pressure (P = 0.022, rate-pressure product (P = 0.045 and exercise duration (P = 0.003 were detected after the procedure. Twenty-seven (32% patients presented angina during the exercise test before the procedure and 16 (19% after the procedure. The exercise test for the detection of restenosis or new lesion presented 61% sensitivity, 63% specificity, 62% accuracy, and 67 and 57% positive and negative predictive values, respectively. In patients without restenosis, the exercise duration after percutaneous coronary intervention was significantly longer (460 ± 154 vs 381 ± 145 s, P = 0.008. Only the exercise duration permitted us to identify patients with and without restenosis or a new lesion.

    We investigated whether the benefits of stent implantation over balloon percutaneous transluminal coronary angioplasty (PTCA) for treatment of chronic total coronary occlusions (CTO) are maintained in the long term. Several randomized trials have shown that in CTO, stent implantation confers clinical and angiographic mid-term outcomes superior to those observed after PTCA. However, limited information on the long-term results of either technique is available. Six-year clinical follow-up of patients enrolled in the Gruppo Italiano di Studio sullo Stent nelle Occlusioni Coronariche (GISSOC) trial was performed by direct visit or telephone interview. Major adverse cardiac events (MACE), defined as cardiac death, myocardial infarction, target lesion revascularization (TLR), and anginal status, were recorded. Freedom from MACE at six years was 76.1% in the stent group, compared with 60.4% in the PTCA group (p = 0.0555). This difference was due mainly to TLR-free survival rates (85.1% vs. 65.5% for the stent and PTCA groups, respectively; p = 0.0165). Eleven patients underwent TLR after the nine-month follow-up visit (stent group: n = 5; PTCA group: n = 6); however, in most cases, restenosis of the study occlusion was evident at nine-month angiography. This study represents the longest reported clinical follow-up of patients after percutaneous recanalization of CTO and demonstrates that the superiority of stent implantation over balloon PTCA is maintained in the long term. Stent and PTCA results appear to remain stable after nine-month angiographic follow-up. Stent implantation in CTO that can be recanalized percutaneously is therefore a valuable long-term therapeutic option.

    A prospective study of 111 patients who underwent repeat coronary angiography and exercise thallium-201 scintigraphy 6 +/- 2 months after complete revascularization by percutaneous transluminal coronary angioplasty was performed to assess whether clinical, procedure-related and postangioplasty exercise variables yield independent information for the prediction of angiographic restenosis after angioplasty. Complete revascularization was defined as successful angioplasty of one or more vessels that resulted in no residual coronary lesion with greater than 50% diameter stenosis. Restenosis was defined as a residual stenosis at the time of repeat angiography of greater than 50% of luminal diameter. Restenosis occurred in 40% of the patients. The 111 patients were randomly subdivided into a learning group (n = 84) and a testing group (n = 27). A logistic discriminant analysis was performed in the learning group and the logistic model was used to estimate a logistic probability of restenosis. This probability of restenosis was validated in the testing group. In the learning group of 84 patients univariate analysis of 39 factors revealed 8 factors related to restenosis: recurrence of angina (p less than 0.0001), postangioplasty abnormal finding on exercise thallium-201 scintigram (p less than 0.0001), exercise thallium-201 scintigram score (p less than 0.0001), difference between exercise and rest ST segment depression (p less than 0.001), postangioplasty exercise ST segment depression (p less than 0.001), absolute postangioplasty stenosis diameter (p less than 0.003), postangioplasty exercise work load (p less than 0.03) and postangioplasty exercise heart rate (p less than 0.05)

    Full Text Available Coronary angiography underestimates or overestimates lesion severity, but still remains the cornerstone in the decision making for revascularization for an overwhelming majority of interventional cardiologists. Guidelines recommend and endorse non invasive functional evaluation ought to precede revascularization. In real world practice, this is adopted in less than 50% of patients who go on to have some form of revascularization. Fractional flow reserve (FFR is the ratio of maximal blood flow in a stenotic coronary relative to maximal flow in the same vessel, were it normal. Being independent of changes in heart rate, BP or prior infarction; and take into account the contribution of collateral blood flow. It is a majorly specific index with a reasonably high sensitivity (88%, specificity (100%, positive predictive value (100%, and overall accuracy (93%. Whilst FFR provides objective determination of ischemia and helps select appropriate candidates for revascularization (for both CABG and PCI in to cath lab itself before intervention, whereas intravascular ultrasound/optical coherence tomography guidance in PCI can secure the procedure by optimizing stent expansion. Functional angioplasty simply is incorporating both intravascular ultrasound and FFR into our daily Intervention practices.

    Costs of percutaneous coronary interventions (PCI) have an important impact on health care expenditures. Despite the present stress upon the cost-effectiveness issues in medicine, few comprehensive data exist on costs and resource use in different clinical settings. To assess catheterisation laboratory costs related to use of drugs and single-use devices in patients undergoing PCI due to coronary artery disease. Retrospective analysis of 1500 consecutive PCIs (radial approach, n = 1103; femoral approach, n = 397) performed due to ST segment elevation myocardial infarction (STEMI; n = 345) and non ST-segment elevation myocardial infarction (NSTEMI; n = 426) as well as unstable angina (UA; n = 489) and stable angina (SA; n = 241) was undertaken. Comparative cost analysis was performed and shown in local currency units (PLN). The cath lab costs were higher in STEMI (4295.01 ± 2384.54PLN, p costs were positively correlated with X-ray dose, fluoroscopy, and total procedure times. Patients' age negatively correlated with cath lab costs in STEMI/NSTEMI patients. Cath lab costs were higher in STEMI patients compared to other groups. In STEMI/NSTEMI they were lower in older patients. In all analysed groups costs were related to the level of procedural difficulty. In female patients, the costs of PCI performed via radial approach were higher compared to femoral approach. Despite younger age, male patients underwent more expensive procedures.

    The exposure of radiologists and patient to radiation during coronary angiography and PTCA in Finland was studied using phantom measurements. The effective dose was calculated according to the ICRP 60 recommendations and patients` radiation risk according to the BEIR V report. An adult patient`s mean surface dose was 660 mGy, corresponding to an effective dose of about 11 mSv. The average effective dose to the radiologist performing coronary angiography is about 0.05 mSv per examination. The eye dose to the radiologist who injects contrast medium manually is about 0.5 mSv per procedure, which would suggest a limit of seven procedures per week on the basis of occupational dose limits. The average risk of exposure-induced death (REID) for male patients is about 0.24% and for female patients 0.1%. The average loss of life expectancy (LLE/REID) among patients with an exposure-induced fatal cancer is about ten years. The radiation risk for male patients is underestimated by about 66% if the risk is assessed on the basis of the effective dose instead of organ doses. (Author).

    To evaluate the incidence and clinical presentation of the occlusion of such secondary branches in patients with single vessel coronary artery disease in the left anterior descending artery, who underwent a first elective and successful PTCA. Two hundred and thirteen side branches of 121 patients considered to be at risk. They were divided into group I (GI-85 side branches, 39.9%), if they originated from the atherosclerotic site; and group II (GII-120 side branches, 61.5%), if their origin would be involved during the balloon inflation. In the GI there were 54 septal branches and 31 diagonal branches, and 36& had angiographic evidence of ostium disease. GII was constituted by 77 septal and 51 diagonal branches, and 7.8% of them had evidence of ostium disease. Seven side branches (3.3%) at risk occluded, 4 from GI (4.7%) and 3 (2.3%) from GII. As for the clinical presentation, 57% of them had angina, where as 28.6% showed minor abnormalities in the ECG. No patient elevated its serum CK-MB, and silent occlusion occurred in 43% of them. Occlusion of side branches is a low incidence phenomenon, which happens more often in septal branches with ostium disease that originates from the atherosclerotic site; that about half of the patient had silent occlusion (43%) or mild ischemic manifestations.

    Randomised trials indicate higher rates of stent thrombosis (ST) and target lesion failure (TLF) after percutaneous coronary intervention (PCI) with the Absorb bioresorbable scaffold (BRS) compared with modern drug-eluting stents (DES). We aimed to investigate the outcome of all Swedish patients treated with the Absorb BRS. The Absorb BRS (n=810) was compared with commonly used modern DES (n=67,909). The main outcome measure was definite ST; mean follow-up was two years. Despite being implanted in a younger, lower-risk population compared with modern DES, the Absorb BRS was associated with a higher crude incidence of definite ST at stent level: 1.5 vs. 0.6%, hazard ratio (HR) 2.38 (95% confidence interval [CI]: 1.34-4.23), adjusted HR 4.34 (95% CI: 2.37-7.94); pstent restenosis were similar for BRS and DES. Non-compliance with dual antiplatelet therapy (DAPT) guidelines was noted in six out of 12 BRS ST events. Three very late ST events occurred with the Absorb BRS. In this real-world observational study, the Absorb BRS was associated with a significantly higher risk of definite ST compared with modern DES. Non-compliance with DAPT guideline recommendations was common among Absorb definite ST events.

    Periprocedural myocardial infarction (MI) is a frequent complication of percutaneous coronary intervention (PCI). Statins might reduce its incidence. The aims of the present study are to assess whether such benefit is a class-effect or whether differences exist between various lipid-lowering strategies and whether cardioprotection is exerted by increasing circulating endothelial progenitor cells (EPCs). The REMEDY study will enroll a total of 1080 patients submitted to elective PCI. Eligible patients will be randomized into 4 groups: 1) placebo; 2) atorvastatin (80 mg + 40 mg before PCI); 3) rosuvastatin (40 mg twice before PCI); and 4) rosuvastatin (5 mg) and ezetimibe (10 mg) twice before PCI. Peri-procedural MI is defined as an elevation of markers of cardiac injury (either CK-MB or troponin I or T) values >5x the upper reference limit estimated at the 99th percentile of the normal distribution, or a rise >20 % in case of baseline values already elevated. EPCs will be assessed before, at 24 h and - in a subset of diabetic patients - at 3 months after PCI (EPC-substudies). The primary endpoint of the main REMEDY study is the rate of peri-procedural MI in each of the 4 treatment arms. Secondary endpoints are the combined occurrence of 1-month major adverse events (MACE, including death, MI, or the need for unplanned revascularization); and any post-procedural increase in serum creatinine. Endpoints of the EPC-substudies are the impact of tested regimens on 1) early (24-h) and 3-month EPC levels and functional activity; 2) stent strut re-endothelialization and neointimal hyperplasia; 3) 1-year MACE. REMEDY will add important information on the cardioprotective effects of statins after PCI.

    Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide with a prevalence that has now reached pandemic levels as a consequence of the rapid modernization of the developing world. Its presentation as an acute coronary syndrome (ACS) is a frequent reason for hospital admission and of profound implications for personal, societal and global health. Despite improvements in the management of ACS with anti-platelet and anticoagulant therapy and revascularization techniques, many patients continue to suffer recurrent ischemic events. The need to reduce future cardiovascular events has led to the development of novel therapies to prevent coronary thrombosis, targeting thrombin-mediated pathways. These include direct Xa inhibitors (apixaban, rivaroxaban and darexaban), direct thrombin inhibitors (dabigatran) and PAR 1 antagonists (vorapaxar and atopaxar). This article critically reviews the comparative mechanisms of action, the risks and benefits, together with the clinical evidence base for the use of these novel oral agents in the management of ACS patients.

    Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

    Cannabis is one of the most widely used illicit substances worldwide, and it has the highest prevalence among drugs used in Egypt. The aims were to evaluate whether the use of cannabis is a risk factor of acute coronary heart disease in low-risk, young males and to compare the cardiac pathological changes between cannabis exposed and non-exposed ischemic patients. This was a cross-sectional study that was performed on 138 male patients, aged ≤ 40 years, with acute myocardial infarction who were admitted to the Cardiac Care Unit at the University Hospital. Urine samples were submitted for toxicological analysis using a homogenous enzyme immunoassay technique to determine the substance of use. The patients were divided into three groups: group 1 (n = 23), cannabis-positive only patients; group 2 (n = 28), patients positive for any other substance of use; and group 3 (n = 34), patients negative for any substance of use. Smoking was prominent, whereas group 1 had no other risk factors. In groups 1 and 2, ST-segment elevation myocardial infarction (STEMI) was dominant, whereas no ST-segment elevation myocardial infarction (NSTEMI) was prominent in group 3. Ischemic resting wall motion abnormalities were presented in 47.8% of group 1 and in only 11.8% of group 3. None of group 1 had normal coronaries, whereas 14.3% of group 3 had normal coronaries. Significant changes in echocardiography and angiography were observed between group 1 and other groups. Cannabis smoking could be a potential risk factor for the development of cardiac ischemia.

    Full Text Available Spasm of the coronary arteries is a dynamic narrowing of one or more coronary arteries, leading to significant restriction of the lumen. The leading role in coronary  artery spasm diagnostic belongs to coronary  angiography and its accompanying provocative tests. Mechanisms of coronary  artery spasm development remain incompletely clarified and it's considered as a multifactorial disease with its own specific risk factors.  Though pathophysiology is no longer a matter of dispute, further  efforts should be aimed at the practical application of the recommendations. Diagnosis of the coronary  artery spasm  has important practical significance, due to the prevailing benefit of calcium antagonists in the treatment and absence of benefit from percutaneous coronary  interventions in most cases. A clinical case of the patient with multivessel, multifocal coronary  artery spasm is presented.

    To evaluate the outcomes of angioplasty for recanalization after acute ischemic stroke (AIS). The study population was selected from 134 patients who underwent endovascular revascularization therapy (ERT) for AIS between October 2011 and May 2014. Of those 134 patients, 39 who underwent balloon angioplasty with or without stent insertion were included in this study. Balloon angioplasty was the primary treatment for nine patients and a rescue method for 30 patients. The revascularization rate at 7 days, procedure-related complications, and clinical outcomes at 3 months were analyzed. The occlusion sites were the middle cerebral artery (n = 26), intracranial internal carotid artery (n = 10), and middle cerebral artery branch (n = 3). Angioplasty achieved successful revascularization (Thrombolysis in Cerebral Ischemia grade 2b–3) in 76.9% of patients. Computed tomography angiography performed 7 days post-procedure revealed a maintained reperfusion in 82.8% of successful cases. Only two patients had symptomatic intracerebral hemorrhage. At the 3-month follow-up, 18 (48.6%) and 10 (27.0%) patients showed good and poor functional outcomes, respectively (modified Rankin Scale scores, 0–2 and 5–6). Emergent balloon angioplasty and bailout self-expandable stent placement may be safe and effective for achieving successful revascularization in acute large vessel occlusion of the anterior circulation. It could be a feasible rescue method as well as a primary method for ERT

Emergent balloon angioplasty and bailout self-expandable stent placement may be safe and effective for achieving successful revascularization in acute large vessel occlusion of the anterior circulation. It could be a feasible rescue method as well as a primary method for ERT.

    Full Text Available No período de abril de 1980 a março de 1990, foram realizadas oito cirurgias de angioplastia de óstio e/ou tronco de coronária esquerda ou direita. Não houve mortalidade imediata e esses pacientes foram acompanhados por um período de 1-109 meses (43,2 meses. Houve melhora clínica e de classe funcional. Seis pacientes fizeram estudo cineangiográfico das coronárias e do ventrículo esquerdo, revelando uma anatomia de óstio e tronco adequada na área operada, e melhora da contratilidade do ventrículo esquerdo. Na evolução tardia houve dois óbitos. Um paciente morreu a 39 meses do pósoperatório, com insuficiência cardíaca congestiva e dor anginosa; o outro faleceu em acidente rodoviário, após 109 meses da cirurgia. Estes resultados permitem concluir que a angioplastia por lesões obstrutivas em óstio ou tronco coronário direito ou esquerdo, isoladas ou associadas a outros defeitos, é um procedimento cirúrgico com baixo risco imediato, com evolução favorável a longo prazo e que pode ser considerado como tratamento opcional para revascularizaçáo coronária.Between April 1980 and March 1990 we performed eight surgical angioplasties of the left main coronary artery and/or its ostium and of the right coronary artery's ostium. There was no early mortality, and these patients were followed by a period of one to 109 months (medium of 43.2 months. We have observed improvement in the clinical symptoms and functional class. A new angiocardiography was performed in six patients, for angioplasty control and left ventricular (L V function evaluation if there was an adequate anatomy on the surgical corrected site and an improvement on the L V contractility and ejection fraction. There were two late deaths. One patient died 39 of postoperative months in congestive heart failure and with angor pectoris, the other one in a car accident 109 months after the surgical correction. These results lead us to conclude that surgical angioplasty

    Diagnosing acute coronary syndrome (ACS) in the emergency department is often a complex process. Inflammatory markers might be useful for the rapid assessment of a patient's overall risk and might also help predict future episodes. The clinical use of these biomarkers could potentially lower the number of emergency visits and help in the prevention of future adverse events. The aim of this review was to evaluate the clinical utility of markers of cardiovascular inflammation in emergency patients with ACS. Based on a critical analysis of a selection of the literature, we concluded that none of the biomarkers of cardiovascular inflammation would at present be useful for stratifying risk in emergency situations, aiding prognosis, or guiding therapy for patients with ACS.

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application

    Recently, endovascular interventions such as balloon angioplasty, atherectomy and the stenting method, except for conventional surgery have been clinically employed for the patients with atheromatous plaques of the peripheral- and the coronary arteries, because the number of patients with arteriosclerosis is now increasing in the worldwide. Among these procedures, restenoses after endovascular interventions have been remarkably disclosed in 20-40 % of the patients who underwent percutaneous coronary interventions. Thus, there are still some problems in keeping long-term patency by means of endovascular techniques such as balloon angioplasty and atherectomy (1, 2). For reduction of these problems , laser angioplasty using Argon laser was applied experimentally and clinically. Based on excellent experimental studies, laser was employed for 115 patients with stenotic ,or obstructive lesions occluding more thasn 75 % of the peripheral and the coronary arteries angiographycally.

    Full Text Available True spontaneous coronary artery dissection (SCAD is an extremely rare but important cause of acute coronary syndrome, with only about 200 cases reported in the literature. Diagnosis is often made at autopsy. Risk factors include oral contraceptive use, atherosclerotic disease and the peripartum period. SCAD should be considered when a healthy young patient presents with the onset of acute myocardial ischemic syndrome. A timely diagnosis and intervention are mandatory as SCAD can cause sudden death. We present a case of SCAD with an uncommon clinical presentation of acute coronary syndrome and without identifiable risk factors, and successfully treated with non-invasive (medical therapy.

    Extent of angiographic lesions, size of infarct and in-hospital and distant prognosis in patients with the metabolic syndrome have been not clearly determined. Detailed knowledge of markers both for ACS occurrence as well as those affecting early and further prognosis will have key significance at taking correct preventive and therapeutic decisions. Comparing in patients with first ACS treated with coronary angioplasty the advancement of coronary disease and the cardiovascular risk evaluated using GRACE 2.0 risk score and the size of the left ventricular ejection fraction depending on co-occurrence of metabolic syndrome Methods: The research was conducted in the group of 160 subsequent patients of the Cardiology Clinic of PUM, hospitalized due to their first in life ACS, treated using the coronary angioplasty, being at the age of 18-70 years. . For all patients the coronarography, that is performed as a routine before angioplasty, was assessed. Before checking out of the hospital the echocardiographic test of the left ventricle function was performed. In all patients the metabolic syndrome was evaluated according to NCEP ATP III criteria. In blood samples taken from the patients the following was marked using routine methods: heart necrosis markers, creatinine concentration ionogram, lipid profile, glucose and insulin concentration, and homeostatic model was calculated. On the basis of acquired data, for all patients the cardiovascular risk was evaluated according to GRACE 2.0 score, using a computer calculator available in the GRACE 2.0 Internet site (www.gracescore.org). Statistical analysis of obtained results was performed using the STATISTICA software varsion 12.0 from StatSoft Inc. Metabolic syndrome criteria were met by 53.5% of examined patients. The examined patients, regardless occurrence of metabolic syndrome, were not different in angiographic advancements of coronary disease and cardiovascular risk as evaluated with the GRACE 2.0 score.

    Little is known in our country about regional differences in the treatment of acute coronary disease. To analyze the behavior regarding the use of demonstrably effective regional therapies in acute coronary disease. A total of 71 hospitals were randomly selected, respecting the proportionality of the country in relation to geographic location, among other criteria. In the overall population was regionally analyzed the use of aspirin, clopidogrel, ACE inhibitors / AT1 blocker, beta-blockers and statins, separately and grouped by individual score ranging from 0 (no drug used) to 100 (all drugs used). In myocardial infarction with ST elevation (STEMI) regional differences were analyzed regarding the use of therapeutic recanalization (fibrinolytics and primary angioplasty). In the overall population, within the first 24 hours of hospitalization, the mean score in the North-Northeast (70.5 ± 22.1) was lower (p Southeast (77.7 ± 29.5), Midwest (82 ± 22.1) and South (82.4 ± 21) regions.

    Reperfusion of myocardial infarction (MI) leads to a reversible dysfunction of coronary vessels. We hypothesised that vasodilating drugs such as nitrates might improve sestamibi uptake within viable areas of recently reperfused MI, thereby enhancing prediction of subsequent improvements in perfusion and contractility. This study was aimed at assessing nitrate-enhanced sestamibi gated SPECT after MI reperfusion. Twenty-nine patients underwent rest followed by nitrate sestamibi gated SPECT at 9 {+-} 3 days after primary angioplasty for acute MI and at follow-up, 4-10 months later. Four MBq/kg of {sup 99m}Tc-sestamibi was injected at rest, and 12 MBq/kg after nitroglycerin spray. Follow-up improvements were documented for both perfusion (P+) and contractility (C+) in 18% of the 180 initially abnormal segments, in neither perfusion (P-) nor contractility (C-) in 44%, in contractility only (C+P-) in 16% and in perfusion only (C-P+) in 22%. Perfusion improvement was related to lower sestamibi uptake on baseline rest SPECT (P+: 42 {+-} 15% vs P-: 50 {+-} 15%, p = 0.001) and, moreover, to a higher increase between rest and nitrate uptake (P+: +9.5 {+-} 6.5% vs P-: +2.0 {+-} 5.9%, p < 0.001). Contractility improvement was related to sestamibi uptake on baseline nitrate SPECT (C+: 58 {+-} 15% vs C-: 38 {+-} 16%, p < 0.001), a variable enhancing the prediction provided by sestamibi uptake at rest (p < 0.05). The improvement in perfusion which is documented in the months following MI reperfusion is predicted by initial nitrate enhancement of sestamibi uptake, suggesting a mechanism of reversible vascular injury. In this particular setting, sestamibi uptake is a better predictor of contractility recovery when determined after nitrate administration rather than under conventional resting conditions. (orig.)

    Full Text Available Patients with coronary artery anomalies are more susceptible to develop acute thrombotic coronary occlusions due to the abnormal anatomy of these arteries and the disturbance of the pathophysiological mechanisms that lead to an accelerated atherosclerosis development. The following article presents the case of a 64-year-old female patient diagnosed with anterior ST-segment elevation myocardial infarction. The patient underwent primary percutaneous coronary intervention, which revealed the absence of the right coronary artery and separated origins of the left anterior descending artery and the left circumflex artery from the aorta.

In several multicenter studies, the possibility of treating coronary artery disease by percutaneous coronary intervention with implantation of endoluminal prosthesis or stent is suggested. The objective of this research was to characterize percutaneous angioplasty with stent in the left main coronary artery. Method: An observational, descriptive and transversal study was carried out in 21 patients with percutaneous angioplasty with stent in the left main coronary artery, performed in the laboratory of Hemodynamics and Interventional Cardiology of Hermanos Ameijeiras Hospital, between January 2010 and July 2011. Results: There was no significant difference in sex. The age group 50-64 years (47.6% and white skin color (76.19% were predominant. The most commonly found cardiovascular risk factor was hypertension (85.71%, followed by dyslipidemia (47.61%. Effort angina was the most observed diagnosis with 14 cases (66.66%. The lesion in the body of the trunk (12 patients, 57.1% was the most prevalent, followed by ostial lesion (8 cases. Drug-eluting (61.9% was the most used type of stent and only 4 patients had surgically protected trunks. Conclusions: Most cases were elective, with a predominance of unprotected trunks. Hypertension was the coronary risk factor most commonly found. A significant association between diabetes mellitus and ostial location of the lesion was found.

During the procedure and stay in the Intensive Coronary Unit, the occurrence of fever, hypotension or hypertension, chills, sudoresis, bleeding, nausea and vomits were observed. Seven products were evaluated: catheter introducer, catheter guides (0.35 and 0.014, catheter balloons for angioplasty, indeflators and manifolds. In total, 76 brand-new and 410 reused apparatuses were studied to verify the occurrence of discard, whether this happened before or during the procedure and for what reasons. P-values < 0.05 were considered signicant. RESULTS: Twenty-six patients presented adverse effects. Hypotension was the most common seen in 11(18.3% cases. There was no significant association between this adverse effect and reuse or not of the equipment. Three brand-new products and 55 of the reused products were discarded as they were incomplete. CONCLUSION: The adverse effects presented by patients submitted to coronary vessel angioplasty were not associated to the reuse of the medical equipment. The integrity and functionality were the main reasons of discard.

    Acute kidney injury (AKI), a common and crucial complication of acute coronary syndrome (ACS) after receiving percutaneous coronary intervention (PCI), is associated with increased mortality and adverse outcomes. This study aimed to develop and validate a risk prediction model for incident AKI after PCI for ACS. We included 82,186 patients admitted for ACS and receiving PCI between 1997 and 2011 from the Taiwan National Health Insurance Research Database and randomly divided them into a training cohort (n = 57,630) and validation cohort (n = 24,656) for risk model development and validation, respectively. Risk factor analysis revealed that age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, chronic kidney disease (CKD), intra-aortic balloon pump (IABP) use, cardiogenic shock, female sex, prior stroke, peripheral arterial disease, hypertension, and heart failure were significant risk factors for incident AKI after PCI for ACS. The reduced model, ADVANCIS, comprised 8 clinical parameters (age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, CKD, IABP use, cardiogenic shock), with a score scale ranging from 0 to 22, and performed comparably with the full model (area under the receiver operating characteristic curve, 87.4% vs 87.9%). An ADVANCIS score of ≥6 was associated with higher in-hospital mortality risk. In conclusion, the ADVANCIS score is a novel, simple, robust tool for predicting the risk of incident AKI after PCI for ACS, and it can aid in risk stratification to monitor patient care.

    Full Text Available Abstract Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists.

    Full Text Available We report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. We present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery - the theories and treatments are discussed. A 85 year-old female was admitted under the care of the cardiothoracic team with signs and symptoms of heart failure. Investigations, including cardiac echocardiography and coronary angiography, indicated a critical aortic valve stenosis. Intraoperative right ventricular failure ensued post aortic valve replacement. Subsequent investigations revealed an acute occlusion of the proximal right coronary artery with resultant absence of distal flow supplying the right ventricle. An immediate right coronary artery bypass procedure was performed with resolution of the right ventricular failure. Subsequent weaning off cardiopulmonary bypass was uneventful and the patient continued to make excellent recovery in the postoperative phase. To our knowledge this is one of the few documented cases of intraoperative acute coronary artery occlusion developing during valve surgery. However, surgeons should be aware of the potential for acute occlusion so that early recognition and rapid intervention can be instituted.

    The long-term prognostic significance of coronary artery dominance pattern in patients with ST-segment elevation myocardial infarction is poorly characterized. We investigated the prognosis of such patients according to whether they had right dominance, left dominance, or codominance. This was a retrospective study of 767 patients, who were admitted to hospital between 2007 and 2012 with ST-segment elevation myocardial infarction and treated with primary percutaneous coronary intervention. We determined the effect of the coronary dominance pattern on all-cause mortality and readmission for infarction, adjusting for mortality as a competing event. A total of 80.9% of patients had right coronary dominance, and 8.6% had left coronary dominance. Over 40.8 months' [interquartile range, 21.9-58.3 months] follow-up, 118 (15.4%) deaths were recorded, of which 39 (5.1%) were in hospital. Mortality for right dominance, left dominance, and codominance was 7.1%, 36.4%, and 13.8% (P ˂ .001), respectively. Cause of death was cardiovascular in 7.1%, 21.2%, and 2.4%. On Cox multivariate analysis, left dominance was significantly associated with mortality (hazard ratio = 1.76; P = .02). Taking "coronary dominance" into account in prediction of risk of death improved the discrimination and calibration capacity of GRACE (Global Registry of Acute Coronary Events) scoring. At follow-up, 9.3% (71 patients) had reinfarction. On multivariate analysis, left dominance was an independent predictor of reinfarction (subhazard ratio = 2.06; P = .01). In ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention, left coronary artery dominance confers a higher risk of death and reinfarction than right coronary artery dominance, and should be included in prognostic stratification.

    Background: Advances in computer tomography (CT) imaging technology in recent years have facilitated the possibility of noninvasive coronary angiography. Purpose: To compare the diagnostic accuracy of 64-channel multidetector computed tomography (MDCT) with conventional invasive coronary angiography (ICA) for the detection of significant coronary stenosis in patients with acute coronary syndrome (ACS). Material and Methods: MDCT was performed in 60 patients classified with non-ST-elevation infarction (NSTEMI) or unstable angina and scheduled for ICA within 3 days. The diagnostic accuracy of MDCT was evaluated using quantitative coronary angiography (QCA) as the gold standard. Results: 48 out of 60 patients had interpretable scans by both MDCT and ICA. On a segment-based analysis, 488 out of 665 segments with a diameter of =1.5 mm, as defined by QCA, were interpretable by MDCT. Sensitivity was 78%, specificity 87%, positive predictive value 47%, and negative predictive value 97% in detecting and excluding significant coronary stenosis, as defined with MDCT. On a per patient-based analysis, sensitivity was 89%, specificity 50%, positive predictive value 84%, and negative predictive value 60%. Conclusion: Limited diagnostic accuracy restricts the usefulness of coronary MDCT in patient groups with a high pretest probability of disease, such as in acute coronary syndrome.

    Atherosclerosis is considered to be an inflammatory disease. Infections are a significant cause of inflammation. Acute infections might precipitate acute coronary syndromes (ACS) whereas chronic infections might be stimuli for the development of atherosclerosis. Coronary angiograms were done on 211 of 335 patients with ACS and the percentage of coronary obstruction was determined. Serum antibody levels to Chlamydia pneumoniae, C. pneumoniae heat shock protein 60 (CpnHSP60), human heat shock protein 60 (hHSP60), enterovirus (EV), herpes simplex virus (HSV), cytomegalovirus (CMV), and two major periodontal pathogens, Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis, were measured in healthy controls (n = 355) and all patients. Serum antibody levels to periodontal pathogens did not correlate with ACS. However, IgA-class antibody levels to Aggregatibacter actinomycetemcomitans (p = 0.021), CpnHSP60 (p = 0.048) an hHSP60 (p = 0.038) were higher in patients with coronary occlusion or obstruction compared to those without any obstruction. Odds ratios for coronary changes in the highest quartile as compared to the lower quartiles were for A. actinomycetemcomitans IgA 7.84 (95% CI 1.02-60.39, p = 0.048), for CpnHSP60 IgA 8.61 (1.12-65.89, p = 0.038), and for human HSP60 IgA 3.51 (0.79-15.69, p = 0.100). We have previously reported that EV and HSV titres correlated significantly to acute coronary events. They do not correlate to the degree of coronary obstruction as shown here. However, infection by A. actinomycetemcomitans or C. pneumoniae or host response against them associated with coronary obstruction. Clinical coronary events may arise by the effect of acute infections and obstructing lesions by a chronic inflammatory stimulus.

    All guidelines recommend primary percutaneous coronary intervention as the default strategy for achieving reperfusion in ST-segment elevation myocardial infarction patients. These recommendations are based upon randomized trials which compared primary percutaneous coronary intervention with stand-alone intravenous fibrinolysis. Since the time these trials were performed, however, it has been shown in further trials that use of rescue percutaneous coronary intervention in patients without signs of reperfusion after lysis, and routine coronary angiography within 24 h of the administration of lysis for all other patients, substantially improved the results of intravenous fibrinolytic treatment. This has led to proposing the pharmaco-invasive strategy as an alternative to primary percutaneous coronary intervention. Actually, it is not uncommon that circumstances prevent performing primary percutaneous coronary intervention within the recommended time limits set by the guidelines. In such cases, using a pharmaco-invasive strategy may constitute a valid alternative. Both the STREAM randomized trial and real-world experience, in particular the long-term results from the FAST-MI registry, suggest that the pharmaco-invasive strategy, when used in an appropriate population, compares favorably with primary percutaneous coronary intervention. Therefore, implementing a pharmaco-invasive strategy protocol may be an important complement to compensate for potential weaknesses in ST-segment elevation myocardial infarction networks.

    We performed periodontal examination and measured serum antibody levels against Prevotella intermedia in patients with acute coronary syndrome (ACS). Composite periodontal risk scores were significantly higher in the ACS group than in the coronary artery disease (CAD) group. Serum antibody levels were higher in the ACS group than in the CAD group and those were significantly correlated with the composite periodontal risk scores. These results provided important information about the status of P. intermedia infection in patients with ACS.

    Direct angioplasty is an effective treatment for ST-elevation myocardial infarction. The role of very early angioplasty in non-ST-elevation infarction is not known. Thus, a randomized study of first day angiography/angioplasty vs early conservative therapy of evolving myocardial infarction without persistent ST-elevation was conducted. One hundred and thirty-one patients with confirmed acute myocardial infarction without ST-segment elevations were randomized within 24 h of last rest chest pain: 64 in the first day angiography/angioplasty group and 67 in the early conservative group (coronary angiography only after recurrent or stress induced myocardial ischaemia). All patients in the invasive group underwent coronary angiography on the day of admission (mean randomization-angiography time 6.2 h). First day angioplasty of the infarct related artery was performed in 47% of the patients and bypass surgery in 35%. In the conservative group, 55% underwent coronary angiography, 10% angioplasty and 30% bypass surgery within 6 months. The primary end-point (death/reinfarction) at 6 months occurred in 6.2% vs 22.3% (P<0.001). Six month mortality in the first day angiography/angioplasty group was 3.1% vs 13.4% in the conservative group (P<0.03). Non-fatal reinfarction occurred in 3.1% vs. 14.9% (P<0.02). First day coronary angiography followed by angioplasty whenever possible reduces mortality and reinfarction in evolving myocardial infarction without persistent ST-elevation, in comparison with an early conservative treatment strategy.

    There remains significant concern about the long-term safety of drug-eluting stents (DES). However, bare metal stents (BMS) have been used safely for over two decades. There is therefore a pressing need to explore alternative strategies for reducing restenosis with BMS. This study was designed to examine whether IVUS-guided cutting balloon angioplasty (CBA) with BMS could convey similar restenosis rates to DES. In the randomised REstenosis reDUction by Cutting balloon angioplasty Evaluation (REDUCE III) study, 521 patients were divided into four groups based on device and IVUS use before BMS (IVUS-CBA-BMS: 137 patients; Angio-CBA-BMS: 123; IVUS-BA-BMS: 142; and Angio-BA-BMS: 119). At follow-up, the IVUS-CBA-BMS group had a significantly lower restenosis rate (6.6%) than the other groups (p=0.016). We performed a quantitative coronary angiography (QCA) based matched comparison between an IVUS-guided CBA-BMS strategy (REDUCE III) and a DES strategy (Rapamycin-Eluting-Stent Evaluation At Rotterdam Cardiology Hospital, the RESEARCH study). We matched the presence of diabetes, vessel size, and lesion severity by QCA. Restenosis (>50% diameter stenosis at follow-up) and target vessel revascularisation (TVR) were examined. QCA-matched comparison resulted in 120-paired lesions. While acute gain was significantly greater in IVUS-CBA-BMS than DES (1.65±0.41 mm vs. 1.28±0.57 mm, p=0.001), late loss was significantly less with DES than with IVUS-CBA-BMS (0.03±0.42 mm vs. 0.80±0.47 mm, p=0.001). However, no difference was found in restenosis rates (IVUS-CBA-BMS: 6.6% vs. DES: 5.0%, p=0.582) and TVR (6.6% and 6.6%, respectively). An IVUS-guided CBA-BMS strategy yielded restenosis rates similar to those achieved by DES and provided an effective alternative to the use of DES.

    2010-01-01

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation.

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS.

Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been...... defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure...... adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and or when urinary output is insufficient after diuretics.

    OBJECTIVES Conclusive evidence is lacking regarding the benefits and risks of performing off-pump versus on-pump coronary artery bypass graft (CABG) for patients with diabetes. This study aims to compare clinical outcomes after off-pump and on-pump procedures for patients with diabetes. METHODS The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial enrolled patients with type 2 diabetes and documented coronary artery disease, 615 of whom underwent CABG during the trial. The procedural complications, 30-day outcomes, long-term clinical and functional outcomes were compared between the off-pump and on-pump groups overall and within a subset of patients matched on propensity score. RESULTS On-pump CABG was performed in 444 (72%) patients, and off-pump CABG in 171 (28%). The unadjusted 30-day rate of death/myocardial infarction (MI)/stroke was significantly higher after off-pump CABG (7.0 vs 2.9%, P = 0.02) despite fewer complications (10.3 vs 20.7%, P = 0.003). The long-term risk of death [adjusted hazard ratio (aHR): 1.41, P = 0.2197] and major cardiovascular events (death, MI or stroke) (aHR: 1.47, P = 0.1061) did not differ statistically between the off-pump and on-pump patients. Within the propensity-matched sample (153 pairs), patients who underwent off-pump CABG had a higher risk of the composite outcome of death, MI or stroke (aHR: 1.83, P = 0.046); the rates of procedural complications and death did not differ significantly, and there were no significant differences in the functional outcomes. CONCLUSIONS Patients with diabetes had greater risk of major cardiovascular events long-term after off-pump CABG than after on-pump CABG. PMID:25968885

    Acute myocardial infarction is thought to occur at sites of minor coronary stenosis. Recent data challenge this and also propose a role for coronary artery movement (CAM) in plaque instability. We examined the relationship between coronary stenosis severity, CAM pattern, and infarct-related lesions (IRLs) in acute myocardial infarction. We investigated 203 consecutive patients with ST-segment elevation myocardial infarction after successful fibrinolysis. Quantitative coronary angiography, CAM pattern, and extent score (atheroma burden) analysis was performed for each coronary artery segment. The IRL stenosis was at least moderate (>50%) and severe (>70%) in 78% and 31% of patients, respectively. Culprit arteries were associated with higher atheroma extent scores (25.2 vs 21.6, P 70% vs Compression CAM was also strongly associated with culprit segments (OR 3.4, 95% CI 2.6-4.5, P compression CAM and stenosis severity were strongly correlated, with the likelihood of a coronary segment having compression CAM progressively increasing with worsening stenosis (OR 56.4, 95% CI 37.9-83.8, P 70% vs relationship between stenosis severity and IRLs. Our study also raises the hypothesis that compression CAM may accelerate atherosclerosis and predispose to plaque vulnerability. Copyright 2010 Mosby, Inc. All rights reserved.

    A 41-year-old woman who was undergoing oral chemotherapy with capecitabine for metastatic breast cancer presented with recurrent episodes of chest pain associated with electrocardiographic signs of diffuse ST segment elevation. After spontaneous pain relief, the electrocardiogram showed ischemic evolution in the anterior precordial leads. Coronary and ventricular angiography, performed 24 h later, showed normal coronary arteries and normal left ventricular function. After therapy with capecitabine was discontinued, the patient did not experience further episodes of chest pain. After a nine-month follow-up, she remains alive, with a good performance status and without clinical evidence of persistent ischemia.

    Spontaneous coronary artery dissection (SCAD) is a rare condition that is often underdiagnosed given limitations of conventional cineangiography. In addition to the diagnostic challenge, the condition poses a major therapeutic dilemma given paucity of literature to guide management. We report the case of a 55-year-old woman, who presented with acute coronary syndrome. Coronary angiography at the time of the index hospitalization revealed type 2 SCAD. She was managed conservatively. Repeat coronary angiography three months later showed complete resolution of the previously noted dissection. Because of the high association between SCAD and fibromuscular dysplasia (FMD), a cross-sectional imaging was performed in this case, which ruled out underlying FMD. The patient has been followed longitudinally since her index event and has had no reported recurrences.

    Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS) or sudden death, which typically affects young women. We reported two cases of black Africans patients, aged 56 and 52 years old, who presented to Abidjan Heart Institute for ACS. Coronary angiography showed spontaneous dissection of the right coronary artery in the first case, and dissection of the distal left anterior descending artery in the second. A conservative approach was preferred. Both patients received antiplatelet agents, beta-blockers, angiotensin converting enzyme inhibitors and statins, with a favorable in-hospital course. These cases highlight SCAD as a possible cause of ACS. Implementation of interventional cardiology in Sub-Saharan Africa will help identify this uncommon cause of ACS.

    2004-11-01

    Full Text Available Abstract Background Although percutaneous coronary intervention (PCI is becoming the standard therapy in ST-segment elevation myocardial infarction (STEMI, to date most patients, even in developed countries, are reperfused with intravenous thrombolysis or do not receive a reperfusion therapy at all. In the post-lysis period these patients are at high risk for recurrent ischemic events. Early identification of these patients is mandatory as this subgroup could possibly benefit from an angioplasty of the infarct-related artery. Since viability seems to be related to ischemic adverse events, we initiated a clinical trial to investigate the benefits of PCI with stenting of the infarct-related artery in patients with viability detected early after acute myocardial infarction. Methods The VIAMI-study is designed as a prospective, multicenter, randomized, controlled clinical trial. Patients who are hospitalized with an acute myocardial infarction and who did not have primary or rescue PCI, undergo viability testing by low-dose dobutamine echocardiography (LDDE within 3 days of admission. Consequently, patients with demonstrated viability are randomized to an invasive or conservative strategy. In the invasive strategy patients undergo coronary angiography with the intention to perform PCI with stenting of the infarct-related coronary artery and concomitant use of abciximab. In the conservative group an ischemia-guided approach is adopted (standard optimal care. The primary end point is the composite of death from any cause, reinfarction and unstable angina during a follow-up period of three years. Conclusion The primary objective of the VIAMI-trial is to demonstrate that angioplasty of the infarct-related coronary artery with stenting and concomitant use of abciximab results in a clinically important risk reduction of future cardiac events in patients with viability in the infarct-area, detected early after myocardial infarction.

    After acute myocardial infarction (MI) coronary microvascular impairment and reduced exercise capacity are both determinant of prognosis. We tested whether non-invasive coronary flow reserve (CFR) performed after MI predicts post-MI exercise capacity (EC). Fifty consecutive patients (pts) (mean age 56.5±11years, 30% women) with a first reperfused ST-elevation anterior MI, and sustained TIMI 3 flow after mechanical reperfusion, underwent prospectively non-invasive CFR in the distal part of the left anterior descending artery (LAD), using intravenous adenosine infusion (0.14mg/kg per minute, within 2min), within 24h after successful primary coronary angioplasty (CFR 1), and 4±1.6months later after a period of convalescence and a cardiac rehabilitation program (CFR 2). CFR was defined as peak hyperaemic LAD flow velocity divided by baseline flow velocity. All pts also underwent semi-supine exercise stress echocardiography (ESE) the same day of CFR 2. ESE was performed at an initial workload of 25-30watts with a 20watts increase at 2-minute intervals. Beta-blockers were withheld 24h before ESE. The mean CFR 2 increased significantly when compared to CFR 1 (2.9±0.65 versus 1.9±0.4, Paptitude after MI. Copyright © 2012. Published by Elsevier SAS.

    Full Text Available Coronary angioplasty is recognized nowadays as the first-choice therapeutic strategy for acute coronary syndrome with ST-segment elevation. Atherosclerotic disease is still the main cause ofthis sickness; however, other disturbances, such is dilated coronariopathy, may favor this coronary event. Although some authors raise that atherosclerosis is the main cause of coronary dilation, it is uncommon that this lipid disorder promotes consequences early in life. We present the case of a 33-year-old female (oral contraceptive user - etinor who had not any apparent coronary risk factor but suffered from inferior acute myocardial infarction. The thrombolysis failed, and fortunately we could perform the angioplasty. Intracoronary thrombosis with distal embolism occurred, that waswhy we administered streptokinase. Possible mechanisms that involve oral contraceptives and dilated coronariopathy are discussed, and angiographic images are shown.

    To compare the short and long-term clinical and angiographic outcomes of drug-eluting stents (DES) versus cutting balloon angioplasty followed by bare metal stents (CBA + BMS) for the treatment of ostial lesions of the left anterior descending coronary artery (LAD). A total of 51 consecutive patients with LAD ostial lesions were treated by DES and all patients had completed 2-year clinical follow-up, 50 consecutive patients with LAD ostial lesions treated by CBA + BMS and followed up for 2 years prior to the DES era (May 2000 to November 2003) served as control group. In DES group, one patient experienced acute myocardial infarction (AMI) during hospitalization, the in-hospital major adverse cardiac event (MACE) was 1.96% (1/51), angiography follow-up data at 6-8 months were available in 29 patients and the in-DES restenosis was 10.3% (3/29), at 2-year clinical follow-up, 1 patient died, 4 patients received target lesion revascularization. Total MACE rate was 9.8% (5/51). In CBA + BMS group, there was no in-hospital death and AMI. Angiographic follow-up at 6-8 months was completed in 28 cases and in-stent restenosis rate was 17.9% (5/28). During 2-year follow-up, there was no death and AMI and 6 patients underwent target lesion revascularization. MACE rate was 12% (6/50) in this group. This study showed that both clinical and angiographic outcomes were comparable between DES and CBA + BMS treated patients with LAD ostial lesions during the 2-year follow up period.

    Cocaine is a well known trigger of acute coronary syndromes. Over the last 10 years levamisole, a veterinary anthelminthic drug has been increasingly used as an adulterant of cocaine. Levamisole was used to treat pediatric nephritic syndrome and rheumatoid arthritis before being withdrawn from the market due to its significant toxicity, i.e. hematological complications and vasculitis. The major complications of levamisole-adultered cocaine reported up to now are hematological and dermatological. The case reported here is of a 25 year old man with a history of cocaine abuse who died at home after complaining of retrosternal pain. Postmortem CT-angiography, autopsy, and chemical and toxicological analyses were performed. An eroded coronary artery plaque was found at the proximal segment of the left anterior descending coronary artery. Two myocardial infarct scars were present in the left ventricle. Microscopic examination of the coronary artery revealed infiltration of eosinophils into the adventitia and intima. Toxicological examination confirmed the presence of cocaine and its metabolites in the peripheral blood, and of levamisole in the urine and pericardial fluid. Eosinophilic inflammatory coronary artery pathologies have been clinically linked to coronary dissection, hypersensitivity coronary syndrome and vasospastic allergic angina. The coronary pathology in the presented case could be a complication of levamisole-adultered cocaine use, in which an allergic or immune-mediated mechanism might play a role. The rise in cocaine addiction worldwide and the increase of levamisole adulterated cocaine highlights the importance of updating our knowledge of the effects of adultered cocaine abuse.

    Full Text Available Background: Disruption of vulnerable plaques is the most common cause of acute coronary syndromes. Intravascular ultrasound facilitates cross-sectional imaging of coronary arteries. We aimed at using IVUS to investigate the morphology and tissue characteristics of atherosclerotic plaques of non-culprit intermediate coronary lesions in non-ST elevation ACS setting. Methods: IVUS assessment of sixty-one intermediate coronary lesions in twenty-eight patients with the diagnosis of Non ST elevation acute coronary syndromes. Ultrasound signals were obtained by an IVUS system using a 40-MHz catheter. Results: Mean age was 53.2 ± 9.1 years. Males = 20 (71.4%. Smoking in 17 (60.7%, hypertension in 16 (57.1%, Dyslipidemia in 12 (42.9% and DM in 8 (28.6%. Culprit vessels represent 42% of affected vessels. Sixty-one intermediate lesions were detected. Twenty-nine lesions in culprit vessels and thirty-two lesions in non-culprit vessels with higher lipidic content in lesions of culprit vessels (P < 0.001 while a higher calcific content in lesions of non-culprit vessels (P < 0.001. Higher calcific content of proximal more than distal lesions (P = 0.048. Negative remodeling in 55.7% of lesions. Conclusions: A higher lipidic content in lesions of culprit vessels, while the lesions of non-culprit vessels were more calcific. Higher calcific content of proximal more than distal lesions was defined as well.

    Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

    Toshiki Kuno

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

    2014-12-01

    Full Text Available Fractional flow reserve (FFR assessment provides anatomical and physiological information that is often used to tailor treatment strategies in coronary artery disease. Whilst robust data validates FFR use in stable ischaemic heart disease, its use in acute coronary syndromes (ACS is less well investigated. We critically review the current data surrounding FFR use across the spectrum of ACS including culprit and non-culprit artery analysis. With adenosine being conventionally used to induce maximal hyperaemia during FFR assessment, co-existent clinical conditions may preclude its use during acute myocardial infarction. Therefore, we include a current review of instantaneous wave free ratio as a novel vasodilator independent method of assessing lesion severity as an alternative strategy to guide revascularisation in ACS.

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

    Full Text Available Methods: A 63-year-old woman with atrial fibrillation presented clinical symptoms and signs of acute ischemia in the right lower extremity on the 17th postoperative day after revision total hip arthroplasty of the left hip for aseptic loosening of femoral component. Aspirin was discontinued 7 days before surgery. Both computed tomography angiography and digital subtraction angiography demonstrated complete occlusion of the right common iliac artery. An emergency catheter-directed thrombolysis with urokinase combined with balloon angioplasty was performed to obtain complete patency of the right common iliac artery. Results: The patient received anticoagulation and antiplatelet therapy postoperatively and was fine at the 2-year follow-up. Conclusions: This case demonstrated that catheter-directed thrombolysis combined with balloon angioplasty could be an efficacious, minimally invasive approach for the treatment of acute embolic occlusion of the common iliac artery. Preoperative anticoagulation for patients undergoing total hip arthroplasty with long-term use of aspirin for atrial fibrillation needs further investigation.

    2016-01-01

    Full Text Available Background: Elevated mean platelet volume (MPV has been proposed as a risk factor for coronary artery disease (CAD and is associated with poor clinical outcome in acute coronary syndrome (ACS. However, some studies have contradictory findings. Hence, we aimed to evaluate the association of MPV with the presence of coronary collateral vessel (CCV in patients with ACS. Objective: To find MPV value in ACS patients and to find the predictive value of MPV in the spectrum of CAD and to examine whether levels of MPV predict the presence of CCVs. Methods: A total of 180 patients with first ACS were included in the study. MPV was measured. All patients underwent coronary angiography to know disease severity and CCVs. The CCVs are graded according to the Rentrop scoring system and according to coronary angiography results; patients were divided into two groups as Group 1 (poor CCV and Group 2 (good CCV. Results: The MPV was 10.74 ± 2 fl in poor collateral group patients and 11.01 ± 1.7 fl in good collateral group (P = 0.421. The presence of CCV was not significantly associated with high levels of MPV. MPV value did not show any prediction of the spectrum of CAD. Conclusion: MPV on admission was not associated with the development of CCV positively in patients with ACS. Furthermore, it is not associated with a number of vessel involvements.

  7. Cardiac troponin T in acute coronary syndrome with renal insufficiency.

    Chew, Huck Chin

    2008-08-01

    Cardiac troponin levels are frequently elevated in patients with chronic renal failure, hence diagnosis of myocardial necrosis is difficult. The prevalence of elevated serum troponin T was determined and its diagnostic value in acute coronary syndrome was assessed in patients with chronic renal insufficiency. A retrospective cross-sectional analysis was performed in 227 patients with chronic renal insufficiency and a diagnosis of unstable angina, non-ST or ST-segment elevation myocardial infarction. All patients had baseline serum troponin T levels measured at previous visits; the baseline troponin T level was raised in 53.3%. Cardiac troponin T levels did not correlate with creatinine levels, and were not affected by dialysis. Mortality after an acute coronary event was high (46.3%). Because of the elevated baseline cardiac troponin T levels, detection of acute coronary syndrome in patients with chronic renal failure requires evaluation of serial cardiac enzyme measurements and serial 12-lead electrocardiograms. Early and definitive cardiac interventions may contribute towards decreasing the mortality rate in this group of patients.

  8. Trastuzumab-Induced Myocardiotoxicity Mimicking Acute Coronary Syndrome

    2012-03-01

    Full Text Available Trastuzumab is an important biological agent in the treatment of HER2-positive breast cancer, with effects on response rates, progression-free survival, overall survival and quality of life. Although this drug is well tolerated in terms of adverse effects, trastuzumab-associated myocardiotoxicity has been described to have an incidence of 0.6–4.5% and in rare cases, the drug can trigger severe congestive heart failure with progression to death or even mimic acute coronary syndrome with complete left bundle branch blockade. In this paper is reported a case of trastuzumab-associated myocardiotoxicity manifesting as acute coronary syndrome in a 69-year-old female. The patient is currently undergoing a conservative clinical treatment that restricts overexertion.The majority of clinical studies report trastuzumab-induced cardiotoxicity as a rare event, and, when present, characterized by mild to moderate clinical signs, the ease of reversibility with pharmacological measures and the temporary discontinuation of the medication. Conversely, it is vital for the oncologist/cardiologist to consider the possibility that trastuzumab-induced cardiotoxicity may manifest itself as a severe clinical case, mimicking acute coronary syndrome, justifying careful risk stratification and adequate cardiac monitoring, especially in high-risk patients.

To date, no studies have evaluated the association of blood transfusion with AKI in patients undergoing PCI. We used a retrospective cohort study of all patients with acute coronary syndrome undergoing PCI from CathPCI Registry (n=1 756 864). The primary outcome was AKI defined as the rise in serum creatinine post procedure ≥0.5 mg/dL or ≥25% above baseline values. AKI developed in 9.0% of study sample. Patients with AKI were older, more often women, and had high prevalence of comorbidities, including diabetes mellitus, hypertension, and advanced stages of chronic kidney disease at baseline. Blood transfusion was utilized in 2.2% of patients. In the overall sample, AKI developed in 35.1% of patients who received transfusion versus 8.4% of patients without transfusion (adjusted odds ratio, 4.87 [4.71-5.04]). In the subgroup of patients who sustained bleeding event and received transfusion, the rate of AKI was significantly increased across all preprocedure hemoglobin levels versus no blood transfusion. Similar findings were seen in the subgroup of patients with no bleeding event. Blood transfusion is strongly associated with AKI in patients with acute coronary syndrome undergoing PCI. Further investigation is needed to determine whether a restrictive blood transfusion strategy might improve PCI outcomes by reducing the risk of AKI. © 2016 American Heart Association, Inc.

    Full Text Available Identification of individuals who are at risk of suffering from acute coronary syndromes (ACS may allow to introduce preventative measures. We aimed to identify ACS-related urinary peptides, that combined as a pattern can be used as prognostic biomarker. Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases. Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75. ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664, which was similar to Framingham risk scoring (c-statistics = 0.644 in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP, combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751 resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001 and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007. In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice.

    Disruption of vulnerable plaques is the most common cause of acute coronary syndromes. Intravascular ultrasound facilitates cross-sectional imaging of coronary arteries. We aimed at using IVUS to investigate the morphology and tissue characteristics of atherosclerotic plaques of non-culprit intermediate coronary lesions in non-ST elevation ACS setting. IVUS assessment of sixty-one intermediate coronary lesions in twenty-eight patients with the diagnosis of Non ST elevation acute coronary syndromes. Ultrasound signals were obtained by an IVUS system using a 40-MHz catheter. Mean age was 53.2 ± 9.1 years. Males = 20 (71.4%). Smoking in 17 (60.7%), hypertension in 16 (57.1%), Dyslipidemia in 12 (42.9%) and DM in 8 (28.6%). Culprit vessels represent 42% of affected vessels. Sixty-one intermediate lesions were detected. Twenty-nine lesions in culprit vessels and thirty-two lesions in non-culprit vessels with higher lipidic content in lesions of culprit vessels ( P  < 0.001) while a higher calcific content in lesions of non-culprit vessels ( P  < 0.001). Higher calcific content of proximal more than distal lesions ( P  = 0.048). Negative remodeling in 55.7% of lesions. A higher lipidic content in lesions of culprit vessels, while the lesions of non-culprit vessels were more calcific. Higher calcific content of proximal more than distal lesions was defined as well.

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

     We compared the efficacy of the Cypher Select (Cordis Corporation, Bridgewater, NJ, USA) sirolimus-eluting stent (SES) versus balloon angioplasty (BA) in in-stent restenosis (ISR) of Taxus or Taxus Liberté paclitaxel-eluting stents (PES; Boston Scientific, Natick, MA, USA) or Cypher/Cypher Select SES. Optimal treatment strategies have not been identified for drug-eluting stent (DES) ISR. Patients with a native coronary artery SES or PES ISR were randomized to SES or BA. In addition, a control group included BMS ISR treated with SES. Angiographic control was performed at 12 months. 281 patients were enrolled. Significant differences favoring SES over BA were noted in immediate and net gain (1.39 ± 0.51 vs. 0.97 ± 0.54 mm, P < 0.0001 and 1.07 ± 0.69 vs. 0.49 ± 0.67 mm, P < 0.0001), 12-month mean luminal diameter (MLD; 2.14 ± 0.62 vs. 1.71 ± 0.55 mm, P < 0.0001) and percent diameter stenosis (%DS; 21 ± 19.24 vs. 29.82 ± 18.47, P = 0.001). There was no significant difference at 12 months between SES and BA in the primary end-point late lumen loss (LLL; 0.37 ± 0.57 vs.0.41 ± 0.63, P = 0.73) and in in-stent binary restenosis (11.1% vs. 14%, P = 0.59). Target-lesion revascularization (TLR) was numerically lower in patients treated with SES (5.9% vs. 13.1%, P = 0.097). There was no difference according to the initial DES. In contrast, significantly higher immediate and net gains and MLD were noted in the BMS control group treated by SES. In this angiographic randomized trial comparing SES and BA in SES or PES restenosis, 12 month MLD, immediate and net gain, and %DS favored SES whereas no difference was noted in LLL. Condensed abstract optimal treatment strategies have not been identified for sirolimus-(SES) or paclitaxel-eluting stent (PES) in-stent restenosis (ISR). We randomized patients with a native coronary artery SES or PES ISR to SES or BA. In addition, a control group included BMS ISR treated with SES. There

    Readmissions following acute myocardial infarction are associated with poor outcomes and a heavy economic burden. There are few evidence-based data on the characteristics and outcomes of patients readmitted following acute coronary syndrome. We explored the incidence and outcomes of patients readmitted after an acute coronary syndrome in the past decade. The study population comprised all acute coronary syndrome patients who were enrolled and prospectively followed up in the biennial Acute Coronary Syndrome Israeli Survey from 2000 to 2013. Multivariate analysis identified factors independently associated with readmission and long-term mortality. There were 13,010 study patients, of whom 556 (4.2%) had an unplanned readmission within 30 days of the index event. Stent thrombosis during the index hospitalisation (odds ratio (OR) 8.43; 95% confidence interval (CI) 4.11-16.07; P65 years; OR 1.28; 95% CI 1.06-1.55; P=0.011), and lack of dual-antiplatelet therapy (OR 1.52; 95% CI 1.25-1.86; Psyndrome was observed between 2000 and 2013 ( Psyndrome comprise an undertreated, high-risk cohort. Our findings indicate that despite a significant decline in readmission rates following acute coronary syndrome over the past decade, readmission within 30 days following acute coronary syndrome still portends a grave outcome.

    The role of angiotensin-converting enzyme inhibitors (ACEI) in contrast-induced acute kidney injury (CI-AKI) is controversial. Some studies pointed out that it was effective in the prevention of CI-AKI, while some concluded that it was one risk for CI-AKI, especially for patients with pre-existing renal impairment. The purpose of this study was to assess the influence of benazepril administration on the development of CI-AKI in patients with mild to moderate renal insufficiency undergoing coronary intervention. One hundred and fourteen patients with mild to moderate impairment of renal function were enrolled before coronary angioplasty, who were randomly assigned to benazepril group (n = 52) and control group (n = 62). In the benazepril group, the patients received benazepril tablets 10 mg per day at least for 3 days before procedure. CI-AKI was defined as an increase of ≥ 25% in creatinine over the baseline value or increase of 0.5 mg/L within 72 hours of angioplasty. Patients were well matched with no significant differences at baseline in all measured parameters between two groups. The incidence of CI-AKI was lower by 64% in the benazepril group compared with control group but without statistical significance (3.45% vs. 9.68%, P = 0.506). Compared with benazepril group, estimated glomerular filtration rate (eGFR) level significantly decreased from (70.64 ± 16.38) ml · min⁻¹·1.73 m⁻² to (67.30 ± 11.99) ml · min⁻¹·1.73 m⁻² in control group (P = 0.038). There was no significant difference for the post-procedure decreased eGFR from baseline (ΔeGFR) between two groups (benazepril group (0.67 ± 12.67) ml · min⁻¹·1.73 m⁻² vs. control group (-3.33 ± 12.39) ml · min⁻¹·1.73 m⁻², P = 0.092). In diabetic subgroup analysis, ΔeGFR in benazepril group was slightly lower than that in the control group, but the difference was not statistically significant. Benazepril has a protective effect on mild to moderate impairment of renal function

    Background Interleukin (IL)-1β, IL-18, and downstream IL-6 are key inflammatory cytokines in the pathogenesis of coronary artery disease. Colchicine is believed to block the NLRP3 inflammasome, a cytosolic complex responsible for the production of IL-1β and IL-18. In vivo effects of colchicine on cardiac cytokine release have not been previously studied. This study aimed to (1) assess the local cardiac production of inflammatory cytokines in patients with acute coronary syndromes (ACS), stable coronary artery disease and in controls; and (2) determine whether acute administration of colchicine inhibits their production. Methods and Results Forty ACS patients, 33 with stable coronary artery disease, and 10 controls, were included. ACS and stable coronary artery disease patients were randomized to oral colchicine treatment (1 mg followed by 0.5 mg 1 hour later) or no colchicine, 6 to 24 hours prior to cardiac catheterization. Blood samples from the coronary sinus, aortic root (arterial), and lower right atrium (venous) were collected and tested for IL-1β, IL-18, and IL-6 using ELISA. In ACS patients, coronary sinus levels of IL-1β, IL-18, and IL-6 were significantly higher than arterial and venous levels (P=0.017, Colchicine administration significantly reduced transcoronary gradients of all 3 cytokines in ACS patients by 40% to 88% (P=0.028, 0.032, and 0.032, for IL-1β, IL-18, and IL-6, respectively). Conclusions ACS patients exhibit increased local cardiac production of inflammatory cytokines. Short-term colchicine administration rapidly and significantly reduces levels of these cytokines.

    ón evaluada, con enfermedad coronaria de dos o más vasos, la cirugía de revascularización ofrece un riesgo significativamente mayor de morbilidad intra-hospitalaria sin comprometer la mortalidad posterior hasta doce meses. En este grupo de pacientes, la angioplastia con stent ofrece mejor perfil de morbilidad post-procedimiento y mayor tasa de reintervención del vaso por falla a 12 meses de seguimiento. Tanto la cirugía como la angioplastia con stent, ofrecen tasas equivalentes de mortalidad hasta los doce meses de seguimiento.Multivessel coronary heart disease is a common cause of revascularization procedures either surgical or by percutaneous intervention with angioplasty and stenting. Clinical outcomes of patients treated by any of these strategies have been addressed in different randomized clinical trials with diverse results favoring one or another procedure. This is a prospective cohort clinical trial aiming to analyze clinical outcomes of 400 patients with coronary heart disease involving two or more vessels comparing the outcomes between surgery and percutaneous intervention with coronary stenting. Baseline clinical characteristics were comparable between these groups. Results: in-hospital mortality rate at 1, 6 and 12 months is similar in both revascularization procedures. Nevertheless, in-hospital morbidity is significantly higher in the coronary artery bypass graft group with higher immediate post-procedural infarct-rate compared to that of the percutaneous coronary intervention (PCI group (4,5% vs. 0%; p = 0,005, a higher infection rate (15,8% vs. 1,6%; p = 0,001 and an extended in-hospital stay in the intensive care unit (21.8% vs. 1,1%; p = 0,001.

    The applicability of Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery scores to left main coronary artery disease (CAD) has been questioned. A simplified alternative is needed for guiding decision making. We evaluated the prognostic value of a simplified angiographic classification in comparison with a Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score-based approach for patients with left main CAD undergoing drug-eluting stent implantation. The proposed approach classified left main CAD as either extensive (n=819), defined as left main bifurcation lesions with an involvement of ostial left circumflex artery or as any left main lesion plus multivessel CAD, or limited (n=453), defined as ostial/midshaft lesions or left main bifurcation lesions without an involvement of ostium of left circumflex artery, alone or plus 1-vessel disease. The databases from 4 prospective Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease studies were pooled, and the primary outcome was a major adverse cardiac event, defined as death, myocardial infarction, or repeat revascularization. During follow-up (median 38 months; interquartile range, 36-61 months), the risk for major adverse cardiac event was significantly higher with extensive than with limited left main CAD (adjusted hazard ratio, 2.13; 95% confidence interval, 1.54-2.94; P Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score tertiles did not effectively stratify these 2 outcome measures.

    Numerous highly complex and sensitive noninvasive imaging techniques have enhanced the care of patients with acute myocardial infarction. Optimum use requires specific objectives to be defined in advance, including a review of the potential impact of the test on subsequent decisions. An additional issue that is subject to scrutiny in the current climate of cost containment relates to the incremental value of a specific examination. The imaging modality to be used will partially depend on other issues, including accessibility, cost, and interindividual or institutional expertise with a particular technique. Major applications in noninvasive imaging in the acute coronary syndromes include the following: (1) diagnosis, including identification of associated diseases and contraindications for acute reperfusion; (2) evaluation and management of complications; (3) determination of prognosis (both early and late); (4) estimation of myocardial viability; (5) assessment of therapeutic efficacy; (6) investigational approaches, including 99mTc-sestamibi tomographic imaging, ultrafast cine computed tomographic scanning, and nuclear magnetic resonance imaging. Previous studies in the prethrombolytic era have documented the powerful impact of radionuclide stress testing on prognosis, but this needs to be reevaluated in the light of the changing current population undergoing stress testing. Preliminary data imply that the prognostic accuracy of stress testing after thrombolytic therapy is diminished. Moreover, the role of the open infarct-related artery in traditional estimates of prognosis requires further study. Noninvasive imaging has multiple applications in the diagnosis and management of patients with acute coronary disease, but the decision to use a specific technology in a particular circumstance mandates good clinical judgment and selectivity. 82 references

    Full Text Available Coronary computed tomography angiography (CCTA has evolved notably over the last decade, gaining an increased amount of temporo-spatial resolution in combination with decreased radiation exposure. The importance of CCTA is emerging especially in vulnerable and young patients who might not have developed a viable collateral vascular network to sustain the circulation to an infarction area during a major adverse coronary event. There are a few well-known markers by which a vulnerable plaque can be assessed and that can predict the subsequent events of sudden myocardial ischemia, such as an increased positive remodeling index (cut-off >1.4, low-attenuation plaque (cut-off 0.7, and napkin-ring sign (NRS. This manuscript presents a series of 3 clinical cases of young patients experiencing symptoms and signs of myocardial ischemia who underwent CCTA in order to assess the composition and functional characteristics of atherosclerotic plaques and their repercussion in developing an acute coronary syndrome.

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    Unprotected left main (ULM) coronary artery disease is encountered in 3%-10% of coronary angiograms and is associated with high mortality. The survival of patients with ULM disease presenting with acute coronary syndromes (ACS) depends on different variables and is lowest in those with cardiogenic shock (CS). The aim of the present study was to estimate the impact of baseline characteristics on the subsequent clinical outcome in patients treated by percutaneous coronary intervention (PCI) of ULM for ACS. One hundred and thirty-four patients were retrieved from our database and followed by phone or physician visit. Patients were classified into two groups according to their presentation (CS/STEMI group: patients presenting with CS or ST-elevation myocardial infarction; NSTEMI/UA group: patients with non-STEMI or unstable angina). Data collected were baseline characteristics, procedural information, and clinical outcome. The primary endpoint was all-cause mortality at 6-month follow-up. The secondary end point was a composite of cardiac death, myocardial infarction, and any repeat revascularisation, i.e., major adverse cardiac events (MACE). Kaplan-Meier curves were computed for survival. Logistic regression determined that hypercholesterolaemia (OR 6.22, p=0.03), high pre-procedural TIMI score (OR 3.89, p=0.01), preserved left ventricular ejection fraction (OR 1.07, p=0.01) and LM as culprit lesion (OR 8.57, p=0.01) protected against development of CS. Primary outcome occurred in 44% of patients in the CS/STEMI group compared to 6% in the NSTEMI/UA group (p<0.001). MACE were observed in 30 patients (48%) of the CS/STEMI group and in 12 patients (19%) of the NSTEMI/UA group (p=0.001). Acute coronary syndrome due to critical ULM stenosis is associated with high mortality even after successful PCI. Patients presenting with CS or STEMI are at particular risk.

    Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC) is a priority. To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS) as a predictor of cardiovascular complications during hospitalization. Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1), point of minimum circumference (2); immediately above the iliac crest (3), umbilicus (4), one inch above the umbilicus (5), one centimeter above the umbilicus (6), smallest rib and (7) the point of greatest circumference around the waist (8).

    Aims To study the effects of smoking restrictions in Germany on coronary syndromes and their associated costs. Methods and results All German states implemented laws partially restricting smoking in the public and hospitality sectors between August 2007 and July 2008. We conducted a before-and-after study to examine trends for the hospitalization rate for angina pectoris and acute myocardial infarction (AMI) for an insurance cohort of 3,700,384 individuals 30 years and older. Outcome measures were hospitalization rates for coronary syndromes, and hospitalization costs. Mean age of the cohort was 56 years, and two-thirds were female. Some 2.2 and 1.1% persons were hospitalized for angina pectoris and AMI, respectively, during the study period from January 2004 through December 2008. Law implementation was associated with a 13.3% (95% confidence interval 8.2, 18.4) decline in angina pectoris and an 8.6% (5.0, 12.2) decline in AMI after 1 year. Hospitalization costs also decreased significantly for the two conditions—9.6% (2.5, 16.6) for angina pectoris and 20.1% (16.0, 24.2) for AMI at 1 year following law implementation. Assuming the law caused the observed declines, it prevented 1,880 hospitalizations and saved 7.7 million Euros in costs for this cohort during the year following law implementation. Conclusions Partial smoking restrictions in Germany were followed by reductions in hospitalization for angina pectoris and AMI, declines that continued through 1 year following these laws and resulted in substantial cost savings. Strengthening the laws could further reduce morbidity and costs from acute coronary syndromes in Germany. PMID:22350716

    Multivessel disease is usually present in almost half of patients with acute coronary syndromes. Angiography is insufficiently accurate to decide on coronary revascularization in moderate nonculprit lesions. There is some debate about the usefulness of fractional flow reserve assessed by intracoronary pressure wire in acute coronary syndromes. We studied the results of using fractional flow reserve values to decide whether to perform coronary revascularization of nonculprit angiographically moderate lesions in patients with acute coronary syndrome and multivessel disease. The fractional flow reserve was used to decide whether to revascularize angiographically moderate nonculprit lesions in a cohort of consecutive patients with acute coronary syndromes recruited in 2 centers. One hundred and seven patients were included. Based on fractional flow reserve values, 81 patients (75.7%) were not revascularized. All lesions studied were revascularized in 26 patients (24.3%). Patient characteristics of the nontreated group and treated group were, respectively, diseased vessels, 1.3 (0.7) vs 1.4 (0.6) (P<.4); fractional flow reserve-studied lesions, 1.2 (0.5) vs 1.1 (0.4) (P=.3); stenosis, 46.1 (8.3)% vs 47.9 (10.3)% (P=.4); fractional flow reserve, 0.86 (0.1) vs 0.70 (0.1) (P<.005). After 1 year of follow-up, no significant differences in major cardiovascular events were observed between groups. There no deaths or nonfatal myocardial infarctions attributable to fractional flow reserve -deferred lesions. Coronary revascularization of the studied lesions was performed in 3 nontreated group patients (3.7%) due to disease progression. Fractional flow reserve assessed by intracoronary pressure wire is useful in deciding whether to revascularize angiographically moderate nonculprit lesions in patients with acute coronary syndrome and multivessel disease.

    disorder in hyperthyroidism but paroxysmal tachycardia and atrial fibrillation are not rare. This can be explained by increased heart rate, cardiac output, blood volume, coronary artery flow and peripheral oxygen consumption in thyreotoxicosis [9]. Patients with coronary arteriosclerosis can develop angina pectoris during thyreotoxic stage, which can be explained by imbalance between cardiac demand and supply. Myocardial damage is often in thyrotoxic patients with chronic hart failure, together with myocardial infarction in patients without coronary disease [2,6]. Congestive heart failure and atrial fibrillation are relatively resistant to digitalis treatment because of high metabolic turn over of medication and excessive myocardial irritability in hyperthyro-idism [6]. Cardiovascular and myopathic manifestations predominate in older hyperthyroid patients (over 60 years and some of them can have only few symptoms of hyperthyroidism [1-3]. Thyrotoxic state characterized by fatigue, apathy, extreme weakness, low-grade fever and sometimes congestive heart failure are designated as apathetic hyperthyroidism. Such patients have small goiters, mild tachycardia and often cool and dry skin with few eye signs [6]. Patients with subclinical hyperthyroidism are at increased risk for atrial fibrillation [9]. Unstable angina and non-Q myocardial infarction (non ST elevation are acute manifestation of coronary artery disease. The acute coronary syndrome of unstable angina, non-Q myocardial infarction and Q-wave myocardial infarction have atherosclerotic lesions of the coronary arteries as a common pathogenic substrate. Errosions or ruptures of unstable atherosclerotic plaque triggered pathophysiologic processes, resulted in thrombus formation at the site of arterial injury. This leads to abrupt reduction or cessation through the affected vessel. Clinical manifestations of unstable angina and non-Q myocardial infarction are similar and diagnosis of non-Q myocardial infarction is made on

    Acute coronary syndromes (ACS) may precipitate up to a third of acute heart failure (AHF) cases. We assessed the characteristics, initial management, and survival of AHF patients with (ACS-AHF) and without (nACS-AHF) concomitant ACS. Data from 620 AHF patients were analyzed in a prospective multicenter study. The ACS-AHF patients (32%) more often presented with de novo AHF (61% vs. 43%; P pulmonary edema were more common manifestations in ACS-AHF (P < .01 for both). Use of intravenous nitrates, furosemide, opioids, inotropes, and vasopressors, as well as noninvasive ventilation and invasive coronary procedures (angiography, percutaneous coronary intervention, coronary artery bypass graft surgery), were more frequent in ACS-AHF (P < .001 for all). Although 30-day mortality was significantly higher for ACS-AHF (13% vs. 8%; P = .03), survival in the 2 groups at 5 years was similar. Overall, ACS was an independent predictor of 30-day mortality (adjusted odds ratio 2.0, 95% confidence interval 1.07-3.79; P = .03). Whereas medical history and the manifestation and initial treatment of AHF between ACS-AHF and nACS-AHF patients differ, long-term survival is similar. ACS is, however, independently associated with increased short-term mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

    We report on two patients with intracranial atherosclerosis of the carotid artery or vertebral artery treated with stent-assisted angioplasty. Both patients have severe intracranial atherosclerosis (>70%) with refractory symptoms despite optimal medical treatment. In both patients, a coronary balloon-expandable stent was successfully placed using a protective balloon technique without procedural complications. The patients were asymptomatic and neurologically intact at a mean clinical follow-up of 13 months. Follow-up angiograms did not show restenosis 3 or 4 months after procedure, respectively. Stent-assisted angioplasty for intracranial atherosclerosis in the elective patient has proven effective, with an acceptable low rate of morbidity and mortality. (orig.)

    Aspirin allergy in a patient with acute coronary syndrome represents one of the more urgent challenges an allergist may face. Adverse reactions to aspirin are reported in 1.5% of patients with coronary artery disease. A history of adverse reaction to aspirin often leads to unnecessary withholding of this medication or use of alternative antiplatelet therapy which may be inferior or more costly. Aspirin therapy has been shown to reduce morbidity and mortality in patients with coronary artery disease. Rapid aspirin challenge/desensitization in the aspirin allergic patient has been consistently shown to be both safe and successful in patients with acute coronary syndromes.

    Limited information exists on whether changes in medical practices over the study decades have affected the outcomes of acute coronary syndrome (ACS) patients who undergo early coronary artery bypass surgery (CABG) during index hospitalisation. Data on trends for early CABG referral and associated outcomes were obtained among 11,485 ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) 2000-2010. Among 11,485 patients, 566 (5%) were referred to early CABG. These patients displayed higher risk characteristics, including Killip class >II, anterior myocardial infarction, greater left ventricular dysfunction, and more frequent use of mechanical ventilation and intra-aortic balloon pump (all ptrend over the study decade (6.7% - 1.7%; p<0.001). One year survival was similar between patients referred to early CABG during the late (years: 2006-2010) vs. early (years: 2000-2005) period (85.7% vs. 90%; log-rank p-value=0.15), whereas, among patients who didn't undergo early CABG, and underwent percutaneous coronary intervention (PCI) or medical management only, enrolment during the late periods was associated with a significant survival benefit (91.5% vs. 88.1%; log-rank p-value<0.001). Over the study decade there was a significant decline in referral for early CABG, without a difference in the one-year mortality between the early and non-early CABG group.

    Full Text Available In recent years, lasers are being utilized in cardiovascular surgery. Since the 1980's we have investigated angioplasty using an Argon laser for patients with obstructive arterial diseases. This technique aims to open the obstructive arterial lumen. Based on the excellent results of experimental studies, the technique has been clinically applied. Laser angioplasty was carried out in 84 patients with stenotic or obstructive lesions occluding more than 75% of peripheral and coronary arteries angiographically. They consisted of 74 cases with intermittent claudication and 10 cases with angina pectoris. Laser angioplasty for the peripheral arterial disease was performed under local anesthesia in the inguinal region under angioscopic guidance. On the other hand, laser coronary angioplasty was simultaneously undertaken at the time of coronary artery bypass grafting for a patient with multiple coronary stenoses. The initial success rate by laser angioplasty for the peripheral artery was 91% in the stenotic lesions and 71% in the obstructive lesions. The cumulative patency rate was 94% in the stenotic lesions and 83% in the occlusive lesions. A follow-up study of 66 months was carried out for patients with clinical success, excluding the cases where an angiogram showed occlusion within 1 week after laser angioplasty. Consequently, excellent long-term results could be clinically obtained. Based on the satisfactory results in the peripheral artery, coronary laser angioplasty was employed in 10 patients with angina pectoris. There were no complications by laser. Thus, the feasibility of laser application was apparently confirmed and laser angioplasty might be recommended for patients with atherosclerotic changes, especially for small arteries.

    2014-01-01

    In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920-1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century. Known today as percutaneous transluminal angioplasty (PTA) in peripheral arteries or percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in coronary arteries, balloon angioplasty has become the method of choice to treat patients with acute myocardial infarction or occluded leg arteries. On the occasion of the 40(th) anniversary of balloon angioplasty, we summarize Grüntzig's life and career in Germany, Switzerland, and the United States and also review the developments in vascular medicine from the 1890s to the 1980s, including Dotter's first accidental angioplasty in 1963. The work of pioneers of catheterization, including Pedro L. Fariñas in Cuba, André F. Cournand in France, Werner Forssmann, Werner Porstmann and Eberhard Zeitler in Germany, António Egas Moniz and Reynaldo dos Santos in Portugal, Sven-Ivar Seldinger in Sweden, and Barney Brooks, Thomas J. Fogarty, Melvin P. Judkins, Richard K. Myler, Dickinson W. Richards, and F. Mason Sones in the United States, is discussed. We also present quotes by Grüntzig and excerpts from his unfinished autobiography, statements of Grüntzig's former colleagues and contemporary witnesses, and have included hitherto unpublished historic photographs and links to archive recordings and historic materials. This year, on June 25, 2014, Andreas Grüntzig would have celebrated his 75(th

    2015-10-01

    Patients with chest pain who present to emergency departments have a significantly higher incidence of acute coronary syndrome (ACS) than patients with chest pain presenting to outpatient settings, so emergency department clinicians should have a lower threshold for considering ACS as an etiology. Evaluating patients with suspected ACS in the emergency department involves obtaining a history, physical examination, electrocardiograms (ECGs), and cardiac troponin measurements in conjunction with risk calculators. These parameters cannot be used individually because, for example, a normal ECG result does not exclude ACS and troponin levels can be elevated in many conditions. All patients with suspected ACS should receive aspirin, if not contraindicated, as soon as possible. Those with an ST-segment elevation myocardial infarction (STEMI) or those without STEMI who are in unstable condition should be triaged to undergo reperfusion therapy, typically via percutaneous coronary intervention (PCI), within 120 minutes of first medical contact. If that time limit cannot be met because the patient must be transferred to a PCI-capable facility, fibrinolytic therapy should be initiated within 30 minutes of presentation if STEMI is present. (Fibrinolytic therapy is contraindicated for myocardial infarction without STEMI.) Patients also should receive nitroglycerin to relieve angina and beta blockers if not contraindicated.

    The objective of this review was to summarize evidence gathered for the prognostic value of routine and novel blood lipids and lipoproteins measured in patients with acute coronary syndromes (ACS). Data supports clear association with risk and actionable value for non-high-density lipoprotein (Non-HDL) cholesterol and plasma ceramides in a setting of ACS. The prognostic value and clinical actionability of apolipoprotein B (apoB) and lipoprotein(a) [Lp(a)] in ACS have not been thoroughly tested, while the data for omega-3 fatty acids and oxidized low-density lipoprotein (Ox-LDL) are either untested or more varied. Measuring basic lipids, which should include Non-HDL cholesterol, at the time of presentation for ACS is guideline mandated. Plasma ceramides also provide useful information to guide both treatment decisions and follow-up. Additional studies targeting ACS patients are necessary for apoB, Lp(a), omega-3 fatty acids, and Ox-LDL.

    2011-01-01

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

    Coronary flow reserve (CFR) assessment by transthoracic ultrasound of the left anterior descending (LAD) artery during dipyridamole stress echocardiography has been shown to predict prognosis in large unselected populations. Low values of CFR are strongly correlated with significant stenosis of the LAD; aim of the present study was to assess the prognostic impact of CFR in patients recovering from an acute coronary syndrome (ACS) with proven absence of LAD disease. From an overall cohort of 325 patients with ACS who underwent a high-dose dipyridamole stress with combined assessment of CFR in the LAD and wall motion, 152 patients without LAD disease (stenosis <50%) were included in the present analysis; all subjects underwent coronary angiography and were subsequently monitored for the incidence of major cardiac events (MACE). After a median follow-up of 29 months, 22 patients developed MACE. Patients who experienced MACE differed from stable patients in terms of age, prevalence of diabetes, and CFR. Receiver-operating characteristic curve analysis defined a CFR <2.25 as the optimal cut point for prediction of MACE. Cox multivariable analysis for the prediction of MACE demonstrated independent predictive value only for CFR <2.25, smoking status, and number of stenotic vessels at angiogram. In high-risk patients with ACS, even in the absence of LAD disease, CFR significantly improves prediction of adverse events when added to standard evaluation. This finding supports a role of CFR in the risk stratification early after ACS and is in context with the concept that CFR reflects global atherosclerotic burden, endothelial dysfunction, and microvascular damage, more than just mirroring focal LAD disease.

    Full Text Available BACKGROUND: Acute coronary syndrome (ACS is common in patients approaching the end-of-life (EoL, but these patients rarely receive palliative care. We compared the utility of a palliative care prognostic tool (Gold Standards Framework (GSF and the Global Registry of Acute Coronary Events (GRACE score, to help identify patients approaching EoL. METHODS AND FINDINGS: 172 unselected consecutive patients with confirmed ACS admitted over an eight-week period were assessed using prognostic tools and followed up for 12 months. GSF criteria identified 40 (23% patients suitable for EoL care while GRACE identified 32 (19% patients with ≥ 10% risk of death within 6 months. Patients meeting GSF criteria were older (p = 0.006, had more comorbidities (1.6 ± 0.7 vs. 1.2 ± 0.9, p = 0.007, more frequent hospitalisations before (p = 0.001 and after (0.0001 their index admission, and were more likely to die during follow-up (GSF+ 20% vs GSF- 7%, p = 0.03. GRACE score was predictive of 12-month mortality (C-statistic 0.75 and this was improved by the addition of previous hospital admissions and previous history of stroke (C-statistic 0.88. CONCLUSIONS: This study has highlighted a potentially large number of ACS patients eligible for EoL care. GSF or GRACE could be used in the hospital setting to help identify these patients. GSF identifies ACS patients with more comorbidity and at increased risk of hospital readmission.

    Since identification of aspartate aminotransferase as the first cardiac biomarker in the 1950s, there have been a number of new markers used for myocardial damage detection over the decades. There have also been several generations of troponin assays, each with progressively increasing sensitivity for troponin detection. Accordingly, the "standard of care" for myocardial damage detection continues to change. The purpose of this paper is to review the clinical utility, biological mechanisms, and predictive value of these various biomarkers in contemporary clinical studies. As of this writing, a fifth "next" generation troponin assay has now been cleared by the US Food and Drug Administration for clinical use in the USA for subjects presenting with suspected acute coronary syndromes. Use of these high-sensitivity assays has allowed for earlier detection of myocardial damage as well as greater negative predictive value for infarction after only one or two serial measurements. Recent algorithms utilizing these assays have allowed for more rapid rule-out of myocardial infarction in emergency department settings. In this review, we discuss novel assays available for the risk assessment of subjects presenting with chest pain, including both the "next generation" cardiac troponin assays as well as other novel biomarkers. We review the biological mechanisms for these markers, and explore the positive and negative predictive value of the assays in clinical studies, where reported. We also discuss the potential use of these new markers within the context of future clinical care in the modern era of higher sensitivity troponin testing. Finally, we discuss advances in new platforms (e.g., mass spectrometry) that historically have not been considered for rapid in vitro diagnostic capabilities, but that are taking a larger role in clinical diagnostics, and whose prognostic value and power promise to usher in new markers with potential for future clinical utility in acute coronary

    Ischemic heart disease presents different features in men and women. We analyzed the relation between gender and prognosis in patients who had suffered a high-risk acute coronary syndrome (ACS). This was a prospective analytical cohort study performed at Lozano Blesa University Hospital, Zaragoza, Spain, of 559 patients diagnosed with high-risk ACS with and without ST-segment elevation according to the American College of Cardiology/American Heart Association guidelines. The sample was divided into two groups by gender and differences in epidemiologic, laboratory, electrocardiographic and echocardiographic variables and treatment were recorded. A Cox's proportional hazard model was applied and 6-month mortality was analyzed as the main variable. The median age was 65.2±12.7 years, and 21.8% were women. Baseline characteristics in women were more unfavorable, with higher GRACE scores, older age, higher prevalence of hypertension, diabetes and heart failure, lower ejection fraction and more renal dysfunction at admission. Women suffered more adverse cardiovascular events (27.9% vs. 15.8%, p=0.002). Sixty-four patients died, 18.9% of the women vs. 9.4% of the men (p=0.004). After multivariate analysis, female gender did not present an independent relation with mortality. Hemoglobin level, renal function, ejection fraction and Killip class >1 presented significant differences. Acute syndrome coronary in women has a worse prognosis than in men.

    Ticagrelor is an orally administered antiplatelet agent used to reduce thrombotic events in patients with acute coronary syndromes. Data from two studies in patients with acute coronary syndromes with large amounts of pharmacokinetic (PK) data (phase IIb DISPERSE-2 study (n = 609)); phase III PLATO PK substudy (n = 6,381)), along with non-linear mixed effects modeling software, were used to develop population PK models for ticagrelor and its metabolite, AR-C124910XX, and to evaluate the impact of demographic and clinical factors on the PK of ticagrelor and AR-C124910XX. 32 covariates relating to disease history, biomarkers, clinical chemistry, and concomitant medications were assessed. A one-compartment model with population mean PK parameters of firstorder absorption rate constant (0.67/h), apparent systemic clearance (14 L/h), and apparent volume of distribution (221 L) was shown to best describe the PK profile of ticagrelor. Patients co-administered moderate CYP3A inducers or inhibitors increased (by 110%, 95% confidence interval (CI), 52 - 192%) or decreased (by 64%, 95% CI, 39 - 73%) apparent ticagrelor clearance, respectively, while habitual smoking decreased apparent ticagrelor clearance by 22% (95% CI, 19 - 25%). Ticagrelor bioavailability was 21% (95% CI, 19 - 22%) lower at treatment initiation (visit 1) versus subsequent visits. Compared with Caucasian patients, ticagrelor bioavailability was 39% (95% CI, 33 - 46%) higher in Asian patients and 18% (95% CI, 6 - 28%) lower in Black patients. In the current analyses, the population PK models developed for ticagrelor and AR-C124910XX described the data obtained in the DISPERSE-2 and PLATO studies well, and were consistent with previous phase I PK studies.

    After acute coronary syndrome (ACS), dual antiplatelet therapy (DAPT) is the standard of care for both invasive management with percutaneous intervention and noninvasive (medical) management. Conversely, studies using dual antiplatelet in the population of patients presenting with ACS who undergo coronary artery bypass grafting (CABG) are conflicting. The appropriate antiplatelet regimen after CABG remains an area of controversy. Plaque stability, prevention of graft closure, and secondary thrombosis form the basis for using a second antiplatelet drug, whereas the additional risk of bleeding and lack of conclusive evidence should also be considered. After an extensive literature search, 12 clinical trials with efficacy outcomes were identified. Most of the studies are retrospective, nonrandomized single-center trials. A few large patient populations have been examined using database information. To date, there is only 1 prospective, multicenter, randomized trial published. Recommendations from national guidelines differ, proposing single antiplatelet therapy with aspirin or DAPT with the combination of aspirin and clopidogrel. The purpose of this report is to review the available clinical trial data and provide guidance to practitioners when caring for this patient population. In conclusion, there is no clear consensus regarding the use of DAPT in patients after CABG. If not contraindicated, it is reasonable to use DAPT, starting in the postoperative period, in patients presenting with ACS. Large, multicenter, randomized clinical trials are needed to definitively investigate the role of DAPT in patients with ACS after CABG. Copyright © 2015 Elsevier Inc. All rights reserved.

    Unrecognized renal insufficiency, defined as estimated glomerular filtration rate acute coronary syndrome. We aimed to determine the prevalence and clinical significance of unrecognized renal insufficiency in a large unselected population of patients with acute coronary syndrome. The study population consisted of patients with acute coronary syndrome included in the Acute Coronary Syndrome Israeli biennial Surveys during 2000-2013. The estimated glomerular filtration rate was calculated using the simplified Modification of Diet in Renal Disease formula. Patients were stratified into 3 groups: 1) normal renal function (estimated glomerular filtration rates ≥60 mL/min/1/73 m(2)); 2) unrecognized renal insufficiency (estimated glomerular filtration rates renal insufficiency (estimated glomerular filtration rates acute coronary syndrome patients. Unrecognized renal insufficiency was present in 2536 (19.8%). Patients with unrecognized renal insufficiency were older and more frequently females. All-cause mortality rates at 1 year were highest among patients with recognized renal insufficiency, followed by patients with unrecognized renal insufficiency, with the lowest mortality rates observed in patients with normal renal function (19.4%, 9.9%, and 3.3%, respectively, P renal insufficiency were less frequently referred for coronary angiography and were less commonly treated with guideline-based cardiovascular medications. Acute coronary syndrome patients with unrecognized renal insufficiency should be considered as a high-risk population. The question of whether this group would benefit from a more aggressive therapeutic approach should still be evaluated. Copyright © 2016 Elsevier Inc. All rights reserved.

    For patients with stable coronary artery disease (SCAD), either after hospitalization for acute cardiac events or in the chronic phase, comprehensive treatment programs should be devoted to: (i) reducing mortality and major adverse cardiovascular events, (ii) reducing the ischemic burden and related symptoms, and (iii) increasing exercise capacity and quality of life.Heart rate (HR) has demonstrated to have prognostic value and patients beyond the limit of 70 bpm display increased risk of all the above adverse outcomes, even after adjustment for parameters such as the extension of myocardial infarction and the presence of heart failure. It is well known that a sustained HR elevation may contribute to the pathogenesis of SCAD, being the likelihood of developing ischemia, plaque instability, trigger for arrhythmias, increased vascular oxidative stress, and endothelial dysfunction the mechanisms resulting in this effect. Moreover, high HR could promote chronotropic incompetence, leading to functional disability and reduced quality of life.Despite the strong relationship between HR and prognosis, there is heterogeneity among current guidelines in considering HR as a formal therapeutic target for secondary prevention in SCAD, as far as the cut-off limit. This expert opinion document considered major trials and observational registries in the modern treatment era with beta-blockers and ivabradine, suggesting that an adequate HR control could represent a target for (i), (ii), and (iii) therapeutic goals in SCAD patients with systolic dysfunction (with major evidence for reduced left ventricular ejection fraction SCAD patients with preserved left ventricular ejection fraction. The defined cut-off limit is 70 bpm. To date, there is room for improvement of HR control, since in contemporary SCAD patients HR values <70 bpm are present in less than half of cases, even in the vulnerable phase after an acute coronary syndrome.

    Full Text Available Abstract Background Elevation of cardiac troponin has been documented in multiple settings without acute coronary syndrome. However, its impact on long-term cardiac outcomes in the context of acute decompensated diabetes remains to be explored. Methods We performed a retrospective analysis of 872 patients admitted to Temple University Hospital from 2004–2009 with DKA or HHS. Patients were included if they had cardiac troponin I (cTnI measured within 24 hours of hospital admission, had no evidence of acute coronary syndrome and had a follow up period of at least 18 months. Of the 264 patients who met the criteria, we reviewed the baseline patient characteristics, admission labs, EKGs and major adverse cardiovascular events during the follow up period. Patients were categorized into two groups with normal and elevated levels of cardiac enzymes. The composite end point of the study was the occurrence of a major cardiovascular event (MACE during the follow up period and was compared between the two groups. Results Of 264 patients, 24 patients were found to have elevated cTnI. Compared to patients with normal cardiac enzymes, there was a significant increase in incidence of MACE in patients with elevated cTnI. In a regression analysis, which included prior history of CAD, HTN and ESRD, the only variable that independently predicted MACE was an elevation in cTnI (p = 0.044. Patients with elevated CK-MB had increased lengths of hospitalization compared to the other group (p  Conclusions Elevated cardiac troponin I in patients admitted with decompensated diabetes and without evidence of acute coronary syndrome, strongly correlate with a later major cardiovascular event. Thus, elevated troponin I during metabolic abnormalities identify a group of patients at an increased risk for poor long-term outcomes. Whether these patients may benefit from early detection, risk stratification and preventive interventions remains to be investigated.

    Objective: To observe the clinical effects, safeness and prognosis of delayed percutaneous coronary intervention (PCI) for infarct related artery (IRA) in post-infarct patients. Methods: In total 53 patients with acute myocardial infarction (AMI) underwent delayed PCI within 5-15 days after the acute event. Conventional treatment (including thrombolytic therapy) was given in all patients as they were admitted. Results: Intervention was performed in 68 branches of IRA were, including 64 cases of PTCA followed by stent implantation and 4 cases of direct stent implantation. In total 68 stents were implanted. The TIMI classification was improved from the pre-PCI 0-2 to post-PCI 3. No patient died during the treatment. No repeated AMI, post-infarct angina and repeated recanalization happened in the hospitalization. A 5-48 month follow up showed there was 1 death (1.9%), 1 case of repeated myocardial infarction (1.9%), 3 cases of unstable angina (5.7%), 2 cases of repeated PCI and 1 case of CABG. The rate of repeated recanalization was 5.7%. Seven patients (13.2%) were admitted for the second time, who survived 6-48 months after the intervention. Conclusion: Delayed PCT can obviously improve the short and long term prognosis as well as the life quality of patients with AMI, which is a safe interventional procedure

    To evaluate the efficiency and safety of emergency department (ED) coronary computed tomography angiography (CTA) during a 3-year clinical experience. Single-center registry of coronary CTA in consecutive ED patients with suspicion of acute coronary syndrome (ACS). The primary outcome was efficiency of coronary CTA defined as the length of hospitalization. Secondary endpoints of safety were defined as the rate of downstream testing, normalcy rates of invasive coronary angiography (ICA), absence of missed ACS, and major adverse cardiac events (MACE) during follow-up, and index radiation exposure. One thousand twenty two consecutive patients were referred for clinical coronary CTA with suspicion of ACS. Overall, median time to discharge home was 10.5 (5.7-24.1) hours. Patient disposition was 42.7 % direct discharge from the ED, 43.2 % discharge from emergency unit, and 14.1 % hospital admission. ACS rate during index hospitalization was 9.1 %. One hundred ninety two patients underwent additional diagnostic imaging and 77 underwent ICA. The positive predictive value of CTA compared to ICA was 78.9 % (95 %-CI 68.1-87.5 %). Median CT radiation exposure was 4.0 (2.5-5.8) mSv. No ACS was missed; MACE at follow-up after negative CTA was 0.2 %. Coronary CTA in an experienced tertiary care setting allows for efficient and safe management of patients with suspicion for ACS. (orig.)

    In rural areas of Canada, people with acute coronary syndromes (ACS) can wait up to 32 hours for transfer for diagnostic cardiac catheterization (CATH). While awaiting CATH, it is critical that pain and anxiety management be optimal to preserve myocardial muscle and minimize the risk of further deterioration. The aim of this study was to examine the relationship between clinical management, cardiac pain intensity, and state anxiety for rural ACS patients awaiting diagnostic CATH. In a prospective, descriptive-correlational repeated-measures design involving 121 ACS rural patients, we examined the associations of analgesic and nitroglycerin administration with cardiac pain intensity (numeric rating scale) and state anxiety (Spielberger State Anxiety Inventory) and also nurses' pain knowledge and attitudes (Toronto Pain Management Inventory-ACS Version and Knowledge and Attitudes Survey Regarding Pain) using linear mixed models. The mean age of patients was 67.6 ± 13, 50% were men, and 60% had unstable angina and the remainder had non-ST-elevated myocardial infarction. During follow-up, cardiac pain intensity scores remained in the mild range from 1.1 ± 2.2 to 2.4 ± 2.7. State anxiety ranged from 44.0 ± 7.2 to 46.2 ± 6.6. Cumulative analgesic dose was associated with a reduction in cardiac pain by 1.0 points (numeric rating scale, 0-10) (t108 = -2.5; SE, -0.25; confidence interval, -0.45 to -0.06; P = .013). Analgesic administration was not associated with state anxiety. Over the course of follow-up, ACS patients reported consistently high anxiety scores. Whereas cardiac pain declines in most patients in the early hours after admission, many patients experience a persistent anxious state up to 8 hours later, which suggest that development and testing of protocols for anxiety reduction may be needed. More urgently, the development and examination of a treatment intervention, early on in the ACS trajectory, are warranted that targets pain and anxiety for those for

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

    Full Text Available Allergic reaction-associated acute coronary syndrome picture is defined as Kounis syndrome. Although drug use is the most common cause of allergic reaction, foods and environmental factors may also play a role in the etiology. Herein, a case with acute coronary syndrome that developed two times at 8-month interval due to pseudoephedrine use for upper respiratory tract infection is presented.

    Data on the effect of fasting on coronary disease are rare and controversial. The aim of our study was to investigate the influence of Ramadan on the prevalence of acute coronary syndrome among chest pain patients in the emergency department of Monastir. It was a prospective study, performed in the emergency department of Fattouma Bourguiba University Hospital of Monastir, during the 3 months before, during and after Ramadan from 2012 to 2014. We included all patients with non-traumatic chest pain during the study period. Data were collected using a standardized form. The uniformity chi 2 test, ANOVA test, Kruskal-Wallis test were performed at the 5% level. Binary logistic regression model was used for multivariate analysis. The SCA prevalence was 17% a month before Ramadan, 22% during Ramadan and 28% one month after Ramadan (p = 0.007). According to the results of the multivariate analysis, the period of Ramadan is not associated with increase of risk of SCA whereas the risk doubles after Ramadan in all group (p = 0.001). In subgroups analysis, the period of R was associated with an amplification of risk in men aged more than 55 years and women older than 65 years (OR: 2.1; p = 0.020) and among subjects with hypertension (OR: 2.4, p = 0.007). Ramadan and Shawwal were not associated with an increase of risk among subjects without CVX risk factor. We have demonstrated that the risk of SCA has increased in Ramadan only among the elderly and patient with hypertension. The increased risk in Shawwal can be explained by the lifting of dietary restriction.

  16. The impact of infection on mortality in octogenarians who were admitted due to acute coronary syndrome.

    The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All-cause mortality was defined as the primary endpoint of the study. Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. Copyright © 2018 Elsevier B.V. All rights reserved.

Objective: Compare ACS-related length of stay (LOS, total admission cost, and total admission cost by day of discharge/death for patients who died during an inpatient admission with a matched cohort discharged alive following an ACS-related inpatient stay. Methods: Medical and pharmacy claims (2009–2012 were used to identify admissions with a primary diagnosis of ACS from patients with at least 6 months of continuous enrollment prior to an ACS admission. Patients who died during their ACS admission (deceased cohort were matched (one-to-one to those who survived (survived cohort on age, sex, year of admission, Chronic Condition Index score, and prior revascularization. Mean LOS, total admission cost, and total admission cost by the day of discharge/death for the deceased cohort were compared with the survived cohort. A generalized linear model with log transformation was used to estimate the differences in the total expected incremental cost of an ACS admission and by the day of discharge/death between cohorts. A negative binomial model was used to estimate differences in the LOS between the two cohorts. Costs were inflated to 2013 dollars. Results: A total of 1,320 ACS claims from patients who died (n=1,320 were identified and matched to 1,319 claims from the survived patients (n=1,319.

    Full Text Available BACKGROUND It is observed that anaemia is a common problem in patients hospitalised for acute coronary syndromes. There have been reports in worldwide studies of an association between anaemia and poor prognosis in patients with Acute Coronary Syndromes (ACS. MATERIALS AND METHODS All consecutive patients having ST-elevation myocardial infarction, non-ST elevation myocardial infarction and unstable angina who were admitted in medicine ward, Medicine Intensive Care Unit (MICU, Cardiology Department (CRD, Cardiovascular and Thoracic Surgery (CVTS Department and incidentally found in other departments of Acharya Vinoba Bhave Rural Hospital admitted from 1st November 2014 to 31st December 2015 at AVBRH. Total 200 patients were included in the study. RESULTS Our study showed an association between haemoglobin levels and mean age (p=0.0001, gender (p=0.0001, risk factors like smoking (p=0.035, tobacco (p=0.001 and Killip’s class I (p=0.0001, III (p=0.0001 and IV (p=0.0001. On distribution of the MACE’s during hospital stay stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, heart failure, VT/VF and death (p<0.05 for all. On distribution of the MACE’s during follow up on 30th day and on 180th day stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, re-infarction, heart failure, VT/VF and death (p<0.05 for all. CONCLUSION To conclude our study results, it was found during the study that anaemia as an important risk factor was strongly associated with major adverse outcomes in patients with ACS. Our study suggested that there was a statistically significant correlation between the low Hb levels and MACE’s (post-infarction angina, re-infarction, heart

    Systemic embolization from a primary cardiac tumor is a relatively frequent presentation. However, an acute myocardial infarction due to coronary embolization is rarely seen. We offer an unusual case of a 50-year-old man who presented with severe angina and was diagnosed with an inferolateral ST-segment-elevation myocardial infarction. Aside from otherwise healthy coronary arteries, his coronary angiogram revealed an acute occlusion of the first obtuse marginal branch, which was treated with balloon angioplasty. Because no residual plaque or dissection was found after the angioplasty, an embolic source was suspected. An echocardiogram then revealed a large mobile left atrial myxoma prolapsing into the left ventricle, so the patient underwent minimally invasive resection. Detailed pathologic examination of the myxoma revealed a concomitant high-grade B-cell lymphoma.

    The coronary computed tomography angiography has recently emerged as an accurate diagnostic tool in the evaluation of coronary artery disease, providing diagnostic and prognostic data that correlate directly with the data provided by invasive coronary angiography. The association of recent technological developments has allowed improved temporal resolution and better spatial coverage of the cardiac volume with significant reduction in radiation dose, and with the crucial need for more effective protocols of risk stratification of patients with chest pain in the emergency room, recent evaluation of the computed tomography coronary angiography has been performed in the setting of acute chest pain, as about two thirds of invasive coronary angiographies show no significantly obstructive coronary artery disease. In daily practice, without the use of more efficient technologies, such as coronary angiography by computed tomography, safe and efficient stratification of patients with acute chest pain remains a challenge to the medical team in the emergency room. Recently, several studies, including three randomized trials, showed favorable results with the use of this technology in the emergency department for patients with low to intermediate likelihood of coronary artery disease. In this review, we show data resulting from coronary angiography by computed tomography in risk stratification of patients with chest pain in the emergency room, its diagnostic value, prognosis and cost-effectiveness and a critical analysis of recently published multicenter studies

    It has been shown that cytomegalovirus (CMV) is present in coronary atherosclerotic plaques, but the clinical relevance of this presence remains to be elucidated. In this study we sought to examine CMV infection in atherosclerosis patients defined by different methods and to identify the clinical significance of CMV replication in the atherosclerotic plaques. The study included 105 consecutive patients who were admitted to our department and underwent coronary artery bypass grafting (CABG) surgical interventions. Coronary atherosclerotic specimens as well as 53 specimens from the mamillary artery of these same patients were analyzed. Enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) methods were used for evaluations. The CMV PCR test result was positive for 28 (26.7%) of patients with coronary artery atherosclerosis. After adjusting for other risk factors, coronary artery disease patients with a history of acute coronary syndrome were more likely to be positive for CMV PCR test (P=0.027; odds ratio: 4.2; 95% CI: 1.18-15.0). They were also more likely to have a positive family history for cardiovascular diseases (CVD). This study confirms previous evidence about the replication of CMV virus in the atherosclerotic plaques of coronary arteries and brings clinical significance to this observation by showing a higher prevalence of acute coronary syndromes in those patients with CMV-infected plaques. Our study also suggests a familial vulnerability to CMV replication in the coronary artery walls.

  2. An Unusual Case of Recurrent Hypersensitivity Reaction Associated with Kounis-Like Acute Coronary Syndrome

    2017-01-01

    Full Text Available There have been multiple reports of allergic reactions associated with acute coronary syndromes. This has been classically described as Kounis syndrome. We present an unusual case of 70-year-old male with multiple prior hypersensitivity reactions and history of coronary artery bypass grafting who presented recurrent episode of severe angioedema and anaphylaxis. He responded to epinephrine but subsequently developed a non-ST elevation myocardial infarction with worsening heart failure. Our case is unique in that, unlike classic Kounis syndrome, the acute coronary event in this case did not present concurrently with the allergic reaction; rather it took nearly 48 hours to present. Subsequent angiogram revealed patent grafts and significant decline in the left ventricular systolic function as compared to his own ECHO a year ago. We postulate that slow mediators of inflammation may play a role in delayed development of acute coronary events with associated LV dysfunction following episodes of angioedema and anaphylaxis.

    The aim of this first-in-human study was to assess the safety and effectiveness of the Virtue sirolimus-eluting balloon in a cohort of patients with in-stent restenosis (ISR). Angioplasty balloons coated with the cytotoxic drug paclitaxel have been widely used for ISR treatment. The Virtue angioplasty balloon (Caliber Therapeutics, New Hope, Pennsylvania) delivers sirolimus in a nanoencapsulated liquid formulation. This clinical trial is the first to examine a sirolimus-eluting balloon for ISR. In this prospective, single-arm feasibility study at 9 European centers, 50 ISR patients were treated with the Virtue balloon. Angiographic measurements at 6 months are reported, along with 12-month clinical follow-up. Procedural success in the intention-to-treat population was 100%. The primary safety endpoint was target lesion failure (TLF) (cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization) assessed at 30 days (0%, n = 50). The primary performance endpoint was in-segment late lumen loss (LLL) at 6 months (0.31 ± 0.52 mm; n = 47). Secondary 6-month endpoints include binary restenosis (19.1%), diameter stenosis (30.3 ± 19.9%), and major adverse cardiac events (MACE) (10.2%, n = 49). In the 36-patient per-protocol population (excluding major protocol violations and previously stented ISR), LLL was 0.12 ± 0.33 mm at 6 months. Clinical outcomes at 1 year for the intention-to-treat group were 12.2% TLF and 14.3% MACE and for the per-protocol population were 2.8% TLF and 2.8% MACE. This first-in-human study showed excellent procedural success for the Virtue sirolimus-eluting angioplasty balloon, 6-month LLL rates in line with current stent-free ISR treatment options, and clinical outcomes that warrant further evaluation in dedicated randomized studies.

    Acute coronary syndrome (ACS) may occur during any human activity, including driving. The objectives of this study were to report the frequency of ACS occurring while driving, clarify patient characteristics, and analyze the behavioral patterns of drivers who sustained ACS. A single-center, retrospective observational study was conducted using prospectively acquired data. Among 1605 ACS patients admitted between January 2011 and December 2016, 65 (60 men/5 women) patients who sustained ACS while driving were identified. Clinical variables were compared between these 65 patients and 1540 patients who sustained ACS while performing other activities. Furthermore, multivariable regression analysis was performed to identify variables associated with ACS. The frequency of ACS occurring while driving was 4.0% (65/1605). Compared with patients who sustained ACS while performing other activities, those who sustained ACS while driving were significantly younger (66.2 ± 13.0 vs. 57.5 ± 12.2 years, p current smoking (OR 1.978; 95% CI 1.145-3.417) were associated with ACS. While 55 drivers (85%) who remained conscious after ACS could seek medical attention without causing accidents, the other 10 (15%) who sustained cardiac arrest caused accidents. The association between current smoking and ACS occurring while driving suggests that smoking cessation is advised for smokers who drive from the standpoint of driving safety. We expect that prospective studies be conducted to verify our findings and identify individuals at risk for ACS while driving.

    This study sought to examine the prevalence of insomnia and its association with depression, anxiety, and medical comorbidities in patients after an acute coronary syndrome (ACS). Insomnia increases risk of recurrent cardiac events in ACS patients, but little is known about the prevalence and clinical correlates of insomnia in this setting. Patients (n = 102, 58.3 ± 10.6 years-old) admitted for ACS to a cardiology service at an urban academic medical center completed the Insomnia Severity Index, Epworth Sleepiness Scale, and measures of depression and anxiety. A subset (n = 20) completed ambulatory polysomnography (PSG) in their homes several weeks after discharge. Moderate or severe insomnia was reported by 37% of patients during hospitalization and was associated with 76 minutes more wake after sleep onset measured by home PSG. Although depression and insomnia were strongly associated, about 1 in 4 patients with insomnia did not report significant depressive symptoms. Sleep apnea was documented in 80% of patients on PSG, but insomnia was not associated with sleep apnea, periodic limb movements, demographic factors, or medical conditions other than liver disease. Insomnia is present in over one-third of ACS patients during hospitalization, but at-risk patients could not be readily identified by demographic or medical factors or by depression symptoms.

    Case 1: A 77-year-old woman had effort angina pectoris. Coronary angiography (CAG) revealed a coronary artery aneurysm on the left descending artery. Coronary artery bypass grafting (CABG) and patch angioplasty for the aneurysm were performed. Case 2 : A 69-year-old woman had effort dyspnea CAG showed dilation of the left main trunk and beaded aneurysms (maximum 6 cm in diameter) behind the ascending aorta with a fistula to the right atrium. We closed the fistula and performed CABG to the circumflex branch. Case 3 : A 78-year-old woman had had general fatigue for 2 weeks. Previous CAG had revealed coronary artery aneurysms and current chest computered tomography revealed pericardial effusion. She was, therefore, diagnosed with the rupture of the coronary artery aneurysm. We closed the coronary artery aneurysm and performed CABG. Case 4: A 55-year-old man had been diagnosed with acute myocardial infarction and had undergone percutaneous coronary intervention 3 years before. CAG revealed a coronary artery aneurysm on the right coronary artery. We resected the aneurysm and interposed with saphenous vein graft. Although coronary artery aneurysm often has no symptoms, in the cases of angina, myocardial infarction, rupture or large aneurysm more than 3 times larger than the normal diameter, surgical repair should be considered.

    Acute coronary syndrome (ACS) is a common disease with high mortality and morbidity rates. The methylation status of blood DNA may serve as a potential early diagnosis and prevention biomarker for numerous diseases. The present study was designed to explore novel genome-wide aberrant DNA methylation patterns associated with ACS. The Infinium HumanMethylation450 assay was used to examine genome-wide DNA methylation profiles in 3 pairs of ACS and control group samples. Epigenome-wide DNA methylation, genomic distribution, Gene Ontology (GO) term and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed. The results were confirmed using methylation-specific polymerase chain reaction (MSP) and Sequenom MassARRAY analyses in ACS, stable coronary artery disease (SCAD) and control samples. A total of 11,342 differentially methylated (DM) 5'-C-phosphate-G-3' (CpG) sites were identified, including 8,865 hypomethylated and 2,477 hypermethylated CpG sites in the ACS group compared with the control samples. They varied in frequency across genomic compartments, but were particularly notable in gene bodies and shores. The results of GO term and KEGG pathway enrichment analyses revealed that the methylated genes were associated with certain biological processes and pathways. Despite the considerable variability in methylation data, the candidate selected possessed significant methylation alteration in mothers against decapentaplegic homolog 3 (SMAD3) transcription start site 155 (Chr1:67356838-Chr1:67356942). MSP analysis from 81 ACS samples, 74 SCAD samples and 53 healthy samples, and Sequenom MassARRAY analysis, confirmed that differential CpG methylation of SMAD3 was significantly corrected with the reference results of the HumanMethylation450 array. The data identified an ACS-specific DNA methylation profile with a large number of novel DM CpG sites, some of which may serve as candidate markers for the early diagnosis of ACS.

    OBJECTIVES: To determine the frequency of urgent coronary angiography in patients with acute pericarditis and to examine clinical characteristics associated with coronary angiography. PATIENTS AND METHODS: This is a retrospective analysis of all incident cases of acute viral or idiopathic pericarditis evaluated at Mayo Clinic's site in Rochester, MN, between January 1, 2000, and December 31, 2006. The main outcome measures were use of urgent coronary angiography and rate of concomitant coronary artery disease in patients with pericarditis. RESULTS: There were 238 patients with a final diagnosis of acute pericarditis (mean age, 47.7±17.9 years; 157 [66.0%] were male). On the initial electrocardiogram, 146 patients (61.3%) had ST-segment elevation, and 92 (38.7%) had no ST-segment elevation. Coronary angiography was performed in 40 patients (16.8% of all patients); the frequency was 5-fold higher among those with ST-segment elevation (24.7% vs 4.3%; Ppericarditis, particularly those with ST-segment elevation, typical myocardial infarction symptoms, and elevated troponin T values. Coronary artery disease was present angiographically in one-third of patients undergoing the procedure. Although patients with ST-segment elevation myocardial infarction must receive prompt reperfusion, clinicians must also consider the diagnosis of pericarditis to avoid unneeded coronary angiography.

    Clinico-pathogenetic characteristics of recurrent ulcer disease and acute ulcers were studied in 84 patients with unstable coronary heart disease (CHD). It was found that a relapse of ulcer disease (UD) in CHD presents with moderate abdominal pain without a typical circadian rhythm and with dyspepsia registered, as a rule, for 2 weeks. Acute ulcers often manifested with weak epigastric pain and symptoms of gastric dyspepsia observed usually for several days of hospital treatment. Gastroduodenal bleeding had obscure clinical picture but complicated recurrent UD and acute ulcers in 29.4 and 50% cases, respectively. The recurrence of UD in CHD developed in the presence of focal thrombohemorrhagic disorders of microcirculation in the tissues of gastroduodenal zone, high activity of the acid-peptic factor, low mucus production, hypomotor gastric dyskinesia, detection of Helicobacter pylori (HP).

    Echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. It is the most frequently used cardiovascular diagnostic test after electrocardiography and chest X-ray. However, in a patient with acute chest pain, Transthoracic Echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of ventricular function and the presence of regional wall motion abnormalities, and for ruling out other etiologies of acute chest pain or dyspnea, including aortic dissection and pericardial effusion. Echocardiography is a versatile imaging modality for the management of patients with chest pain and assessment of left ventricular systolic function, diastolic function, and even myocardial and coronary perfusion and is, therefore, useful in the diagnosis and triage of patients with acute chest pain or dyspnea. This review has focused on the current applications of echocardiography in patients with coronary artery disease and myocardial infarction. PMID:23646042

    To determine the strength of the association between the Vital exhaustion syndrome (VES) and acute coronary ischemic events in hospitalized Argentinean sample. VES was measured in 180 patients of both sexes, 90 admitted due to an acute coronary ischemic syndrome (AMI or unstable angina) and a control group of 90 admitted due to an acute non-coronary cardiac event. VES was evaluated with the Maastricht questionnaire during the first week of hospitalization. Dividing the sample in two categories: exhausted and non-exhausted, 57 (63,33%) of the coronary were exhausted, while among the non coronary group, 33 were exhausted (36,66%)(OR=3.1 (1.7-5.8)). The exhaustion score was: control mean score: 17,1 (sd 8,96); case mean score: 21,1 (sd10,60) p: 0.006. Dislipemia was another factor with a significant difference: control 27 (30%) case 44 (62%) OR= 2.2 (1.2-4.1) p=0.01. Logistic regression was performed, including an interaction model between DLP and exhaustion, and it did not show a significant effect. Our results indicate that in Argentina, among other countries as reported in the literature, VES is a psychological condition that is strongly and independent associated to acute coronary events.

    Limited contemporary data compare the clinical and psychosocial characteristics and acute management of patients hospitalized with an initial vs a recurrent episode of acute coronary disease. We describe these factors in a cohort of patients recruited from 6 hospitals in Massachusetts and Georgia after an acute coronary syndrome. We performed structured baseline in-person interviews and medical record abstractions for 2174 eligible and consenting patients surviving hospitalization for an acute coronary syndrome between April 2011 and May 2013. The average patient age was 61 years, 64% were men, and 47% had a high school education or less; 29% had a low general quality of life, and 1 in 5 were cognitively impaired. Patients with a recurrent coronary episode had a greater burden of previously diagnosed comorbidities. Overall, psychosocial burden was high, and more so in those with a recurrent vs those with an initial episode. Patients with an initial coronary episode were as likely to have been treated with all 4 effective cardiac medications (51.6%) as patients with a recurrent episode (52.3%), but were significantly more likely to have undergone cardiac catheterization (97.9% vs 92.9%) and a percutaneous coronary intervention (73.7% vs 60.9%) (P < .001) during their index hospitalization. Patients with a first episode of acute coronary artery disease have a more favorable psychosocial profile, less comorbidity, and receive more invasive procedures but similar medical management, than patients with previously diagnosed coronary disease. Implications of the high psychosocial burden on various patient-related outcomes require investigation. Copyright © 2015 Elsevier Inc. All rights reserved.

    2014-01-01

    In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939–1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called “percutaneous transluminal dilatation”. Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920–1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century. Known today as percutaneous transluminal angioplasty (PTA) in peripheral arteries or percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in coronary arteries, balloon angioplasty has become the method of choice to treat patients with acute myocardial infarction or occluded leg arteries. On the occasion of the 40th anniversary of balloon angioplasty, we summarize Grüntzig’s life and career in Germany, Switzerland, and the United States and also review the developments in vascular medicine from the 1890s to the 1980s, including Dotter’s first accidental angioplasty in 1963. The work of pioneers of catheterization, including Pedro L. Fariñas in Cuba, André F. Cournand in France, Werner Forssmann, Werner Porstmann and Eberhard Zeitler in Germany, António Egas Moniz and Reynaldo dos Santos in Portugal, Sven-Ivar Seldinger in Sweden, and Barney Brooks, Thomas J. Fogarty, Melvin P. Judkins, Richard K. Myler, Dickinson W. Richards, and F. Mason Sones in the United States, is discussed. We also present quotes by Grüntzig and excerpts from his unfinished autobiography, statements of Grüntzig’s former colleagues and contemporary witnesses, and have included hitherto unpublished historic photographs and links to archive recordings and historic materials. This year, on June 25, 2014, Andreas Grüntzig would have celebrated

    Few data exist on the recent trends in the outcome of women hospitalized with acute coronary syndrome. We examined temporal trends in the hospital management and outcomes of women hospitalized with acute coronary syndrome in a real-world setting. We evaluated time-dependent changes in the clinical characteristics, management strategies, and outcomes of women enrolled in the Acute Coronary Syndrome Israeli Surveys (ACSIS) between 2000 and 2010. Periods were categorized as early (2000-2004) and late (2006-2010). Among 11,536 patients enrolled in ACSIS, 2710 (24%) were women. Frequency of women presenting with acute coronary syndrome had declined from 25% in 2000 to 22% in 2010 (P for trend = .002). Women presented less frequently with ST-elevation myocardial infarction and more frequently with associated comorbidities (P change in time to admission among women hospitalized with acute coronary syndrome, temporal change in management strategies over the last decade may have contributed to improved outcomes in this population.

    Full Text Available Aim. To assess the safety of the application of high-dose atorvastatin and its effect on metabolic parameters, such as the total level of nitric oxide and homocysteine in the blood plasma in patients with ischemic heart disease during a coronary artery bypass surgery (CABG.Material and methods. The study included 42 patients with stable effort angina II-IV functional class. A special criterion for selection was the taking atorvastatin at a dose of 20 mg/day for at least 30 days before patient was directed to surgical revascularization of the myocardium. Immediately before the intervention, the dose of atorvastatin was increased to the maximum allowed with subsequent taking of 40 mg/day. Complications after CABG, indicators of lipid metabolism and biochemical safety of statin use were analyzed. The duration of observation of results of the acute atorvastatin recapture therapy was 3 weeks during hospital period. We used modern enzymatic method for nitrogen oxides determination with the application of nitrate reductase. Determination of total homocysteine was performed by high performance liquid chromatography.Results. It was found that atorvastatin 80 mg for 12 hours and 2 hours before CABG in patients previously treated with atorvastatin 20 mg/day is well tolerated and leads to decrease in total levels of nitric oxide by 1.6 (0.18-10.8 μmol/l and homocysteine by 0.9 (0.17-2.69 μmol/l (p< 0.05 for bothConclusion.

    Full Text Available Abstract Background Patient satisfaction constitutes an important indicator for the quality of care. During the last years, Bulgaria changed its socialist health care system to a market-driven system. Despite the fact that the improvement of health care quality and patient satisfaction were put on top of the list of goals for the health care reforms, no studies of patient satisfaction with inpatient care have been conducted so far. Since cardiovascular diseases are amongst the major causes of death in Bulgaria, and strenuous efforts have been made to improve the quality of medical care of patients with acute coronary syndrome (ACS during the last years, patient satisfaction in this group can be seen as an important example of the Bulgarian reforms. This study therefore investigates patient satisfaction of inpatients with ACS. Methods We performed structured face-to-face interviews with all patients with ACS, residing in a representative Bulgarian region who were discharged from hospitals in this region between September 1st and December 31st, 2004. We surveyed their socio-demographic status, overall satisfaction, change in complaints, self-perceived health status, functional possibilities in activities of daily living, satisfaction with life and self-reported condition at admission. We used descriptive methods as well as t-tests, chi-square tests, and logit models for data analysis. Results Face-to-face interviews were carried out in 394 cases, of which 53.6% were men and 46.4% were women. 24% of the patients were satisfied with inhospital treatment, 62% were satisfied to some extent, and 14% were unsatisfied. The overall satisfaction of patients with ACS was significantly associated (p Conclusion ACS patient satisfaction with inhospital treatment in Bulgaria shows much room for improvement. Information obtained from satisfaction studies could be used at decision-making and hospital-management levels for improving new strategies and structural

    More than 4.2 billion inhabitants populate the Asia-Pacific region. Acute coronary syndrome (ACS) is now a major cause of death and disability in this region with in-hospital mortality typically exceeding 5%. Yet, the region still lacks consensus on the best approach to overcoming its specific challenges in reducing mortality from ACS. The Asia-Pacific Real world evIdenCe on Outcome and Treatment of ACS (APRICOT) project reviewed current published and unpublished registry data, unmet needs in ACS management and possible approaches towards improving ACS-related mortality in the region. There was striking heterogeneity in the use of invasive procedures, pharmacologic practice (hospitalization/post-discharge), and in short- and long-term clinical outcomes across healthcare systems; this heterogeneity was perceived to be far greater than in Western Europe or the United States. 'Benchmark' short-term clinical outcomes are preferred over long-term outcomes due to difficulties in follow-up, recording and maintenance of medication adherence in a geographically large and culturally diverse region. Key 'barriers' towards improving outcomes include patient education (pain awareness, consequences of missing medication and secondary prevention), geographical landscape (urban vs. metropolitan), limited long-term adherence to guideline-based management and widespread adoption of cost-based rather than value-based healthcare systems. Initiatives to overcome these barriers should include implementation of pre-hospital management strategies, toolkits to aid in-hospital treatment, greater community outreach with online patient/physician education and telemedicine, sustainable economic models to improve accessibility to effective pharmacotherapies and the acquisition of high-quality 'real-world' regional data to tailor secondary prevention initiatives that meet the unique needs of countries in this region.

    Full Text Available Abstract Background In Australia there is a socioeconomic gradient in morbidity and mortality favouring socioeconomically advantaged people, much of which is accounted for by ischaemic heart disease. This study examines if Australia's universal health care system, with its mixed public/private funding and delivery model, may actually perpetuate this inequity. We do this by quantifying and comparing socioeconomic inequalities in the receipt of coronary procedures in patients with acute myocardial infarction (AMI and patients with angina. Methods Using linked hospital and mortality data, we followed patients admitted to Western Australian hospitals with a first admission for AMI (n = 5539 or angina (n = 7401 in 2001-2003. An outcome event was the receipt, within a year, of a coronary procedure—angiography, angioplasty and/or coronary artery bypass surgery (CABG. Socioeconomic status was assigned to each individual using an area-based measure, the SEIFA Index of Disadvantage. Multivariable proportional hazards regression was used to model the association between socioeconomic status and procedure rates, allowing for censoring and adjustment of multiple covariates. Mediating models examined the effect of private health insurance. Results In the AMI patient cohort, socioeconomic gradients were not evident except that disadvantaged women were more likely than advantaged women to undergo CABG. In contrast, in the angina patient group there were clear socioeconomic gradients for all procedures, favouring more advantaged patients. Compared with patients in the most disadvantaged quintile of socioeconomic status, patients in the least disadvantaged quintile were 11% (1-21% more likely to receive angiography, 52% (29-80% more likely to undergo angioplasty and 30% (3-55% more likely to undergo CABG. Private health insurance explained some of the socioeconomic variation in rates. Conclusions Australia's universal health care system does not guarantee

    Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p definition, only diabetes (adjHR 1.48, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

    Patients with coronary diseases admitted to special care unit often suffer from sleep disorders, which may cause physiological changes and adversely affect patient's health. The relationship between sleep disorders and obesity is an important factor in studies on sleep disorders and other chronic diseases in all groups, including cardiovascular diseases. Understanding this relationship may increase the chance of progress in effective medical interventions in sleep disorders and obesity. This study was designed to evaluate the association between short sleep and Body Mass Index (BMI), hypertension among acute coronary syndrome patients. In this descriptive analytical study, 221 coronary patients admitted to coronary care unit and general wards were investigated. Data were collected through a researcher-made questionnaire whose validity and reliability had been confirmed. Data were analyzed with SPSS-16 software. A total of 221 patients with acute coronary diseases (including myocardial infarction and angina pectoris) with a mean age of 61.27 years were studied, of whom 61.5% were male and 38.5% were female. A significant association was observed between short sleep and higher BMI (P=0.000). About half the patients (49.3%) had a history of hypertension, and sleep disorders were also significantly related to hypertension (P=0.006). In this study, sleep disorders were patients' main complaint. Researchers found that patients with less than 5 hours or more than 9 hours sleep at night were more likely to have hypertension compared to patients that slept 7-8 hours. Lack of sleep affects metabolism, and daily energy expenditure reduces with increased immobility. In this study, a significant relationship was observed between BMI and sleep duration among hospitalized patients in coronary care unit (P=0.000), and sleep disorders increased with higher BMI. Short of sleep increases sympathetic tonus, cortisol level, and activation of inflammatory pathways, impairing glucose

    Full Text Available Abstract Blunt chest trauma might lead to cardiac injury ranging from simple arrhythmias to lethal conditions such as cardiac rupture. We experienced a case of initially overlooked traumatic coronary artery dissection which resulted in acute myocardial infarction (AMI. A high degree of suspicion is needed to diagnose this condition. Based on our case, we will give an overview of relevant literature on this topic. ECG, echocardiography, coronary angiography and cardiac enzymes are valuable tools in diagnosing this rare condition. The time span from coronary artery occlusion to revascularisation must be short if AMI is to be avoided.

    The risk of myocardial infarction is lower among light-to-moderate drinkers compared with abstainers. Results from some previous studies, but not all, suggest that this association is modified by variations in genes coding for alcohol dehydrogenase (ADH). We aimed to test this hypothesis, including alcohol as both the amount of alcohol and the frequency of drinking. we conducted a nested case-cohort study within the Danish Diet, Cancer and Health study, including 1,645 men (770 incident cases of acute coronary syndrome from 1993-1997 through 2004 and 875 randomly selected controls). Higher alcohol intake (measured as amount or drinking frequency) was associated with lower risk of acute coronary syndrome; however, there was no evidence that these finding were modified by ADH1B or ADH1C genotypes. The importance of functional variation in alcohol dehydrogenase for the association between alcohol drinking habits and the risk of developing acute coronary syndrome, if any, is very limited.

    Objective Effective translation of evidence to practice may depend on systems of care characteristics within the health service. The present study evaluated associations between hospital expertise and infrastructure capacity and acute coronary syndrome (ACS) care as part of the SNAPSHOT ACS registry. Methods A survey collected hospital systems and process data and our analysis developed a score to assess hospital infrastructure and expertise capacity. Patient-level data from a registry of 4387 suspected ACS patients enrolled over a 2-week period were used and associations with guideline care and in-hospital and 6-, 12- and 18-month outcomes were measured. Results Of 375 participating hospitals, 348 (92.8%) were included in the analysis. Higher expertise was associated with increased coronary angiograms (440/1329; 33.1%), 580/1656 (35.0%) and 609/1402 (43.4%) for low, intermediate and high expertise capacity respectively; Pcapacity respectively; P=0.056), but not rehabilitation (474/1329 (35.7%), 603/1656 (36.4%) and 535/1402 (38.2%) for low, intermediate and high expertise capacity respectively; P=0.377). Higher expertise capacity was associated with a lower incidence of major adverse events (152/1329 (11.4%), 142/1656 (8.6%) and 149/149 (10.6%) for low, intermediate and high expertise capacity respectively; P=0.026), as well as adjusted mortality within 18 months (low vs intermediate expertise capacity: odds ratio (OR) 0.79, 95% confidence interval (CI) 0.58-1.08, P=0.153; intermediate vs high expertise capacity: OR 0.64, 95% CI 0.48-0.86, P=0.003). Conclusions Both higher-level expertise in decision making and infrastructure capacity are associated with improved evidence translation and survival over 18 months of an ACS event and have clear healthcare design and policy implications. What is known about the topic? There are comprehensive guidelines for treating ACS patients, but Australia and New Zealand registry data reveal substantial gaps in delivery of best

    Full Text Available Background: The periodontal tissues mount an immune inflammatory response to bacteria and their products and the systemic challenge with these agents also induce a major vascular response. Although many studies have found a correlation between chronic periodontitis and cardiovascular diseases, the role of infection in acute coronary syndrome is disputed. The aim of this study is to investigate whether there is an association between chronic periodontitis and acute coronary syndrome. Materials and Methods: A total of 30 patients, ages ranging from 30 -80. 15 patients from A. B. Shetty Memorial Institute of Dental Sciences and 15 patients admitted to Coronary Care Unit of Justice K. S. Hegde Charitable Hospital Deralakatte Mangalore were included in the study. Variables age more than 40 and gender were also analyzed. Results: Of the 30 patients analyzed in this study, periodontitis was recognized in 11 patients of the acute coronary syndrome group and 10 patients in the healthy group. Fisher′s exact test yielded a p value of 0.4539 with an odds ratio of 0.727(95% confidence interval 0.151 to 3.493. Conclusion: No significant association was found between periodontal disease and acute coronary syndrome. Periodontitis may contribute to cardiovascular disease and stroke in susceptible subjects. Properly powered longitudinal case control and intervention trials are needed to identify how periodontitis and periodontal interventions may have an impact on cardiovascular diseases.

    To identify the predictive factors of anxiety and depression in patients with acute coronary syndrome. Cross-sectional and retrospective study conducted with 120 patients hospitalized with acute coronary syndrome. Factors interfering with anxiety and depression were assessed. Anxiety was related to sex, stress, years of education, and depression, while depression was related to sex, diabetes mellitus, obesity, years of education, and trait-anxiety. Obesity and anxiety were considered predictive factors for depression, while depression and fewer years of education were considered predictive factors for anxiety. Copyright © 2017.

    Full Text Available Acute occlusion of left main coronary artery is a catastrophic event. We describe two patients with acute occlusion of the left main coronary artery treated thirty years apart. The first patient was treated in 1982 and survived the event without revascularization but developed severe heart failure. His survival was so unusual that it merited a case report at that time. The second patient was treated at the end of 2015. Early revascularization resulted in myocardial reperfusion and near normal left ventricular function. These patients exemplify the progress in therapeutic cardiology over the last 30 years.

    Full Text Available Background: Long-term adverse cardiovascular effects of smokeless tobacco are well established, however, the effect of chewing tobacco on coronary microcirculation and hemodynamic have not been studied. We intended to analyze the acute effect of chewing tobacco on coronary microcirculation and hemodynamics in habitual tobacco chewers with stable coronary artery disease undergoing elective percutaneous coronary intervention (PCI. Materials and Methods: We prospectively enrolled seven habitual tobacco chewers with stable coronary artery disease with single vessel disease or double vessel disease satisfying the criteria for elective PCI. Patients were instructed to keep 1 g of crushed dried tobacco leaves in the mouth after a successful PCI. Lesion in last stented vessels was evaluated for fractional flow reserve (FFR, coronary flow reserve (CFR, and index of microcirculatory resistance (IMR post-PCI, after 15 min and 30 min of tobacco chewing along with the measurement of serum cotinine levels. Results: Oral tobacco led to high levels of cotinine in the majority of patients. There was an insignificant rise in heart rate, systolic and diastolic blood pressure following tobacco consumption. Baseline CFR (median 1.6, range 1.1–5.5 was low in tobacco chewers after PCI even after optimum FFR (0.9 ± 0.05 in the majority of patients suggesting abnormal microvascular hemodynamics (high IMR in 3 patients, overall median 14.2, range 7–36.2. However, there was no significant change in the estimated CFR or IMR values following tobacco chewing. One patient had bradycardia and hypotension which may be related to vagal reaction or acute nicotine poisoning. Conclusion: Tobacco chewers have abnormal coronary microcirculation hemodynamics even following a successful PCI. However, the coronary micocirculation and hemodynamics do not change acutely following tobacco chewing despite high serum cotinine concentrations.

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that

    Coronary artery disease (CAD) is the major cause of death nearly all over the world, and accurate and rapid diagnosis of CAD is of major medical and economic importance. The aim of this study was to evaluate the serum and saliva levels of cathepsin L in patients with acute coronary syndrome (ACS). In a cross-sectional study, 39 patients with ACS and 28 with controls were recruited to the study, and cathepsin L levels were measured in serum, resting saliva, and stimulated saliva obtained 12 and 24 h after the onset of ACS by ELISA method. Statistical analyses of Fisher's exact test, the Student's t-test or Kruskal-Wallis test were performed. Stimulated saliva cathepsin L levels in patients with ACS 12 hours but not 24 hours after admission showed significant decrease compared with that in control subjects. However, there were no significant differences in serum and unstimulated saliva cathepsin L levels between groups. Serum and saliva levels of cathepsin L remain unchanged in patients with ACS and hence may not be a promising factor in CAD risk assessment. It seems that serum and saliva cathepsin L may not be a good biomarker for CHD.

    Gender-related differences in mortality of acute coronary syndrome (ACS) have been reported. The extent and causes of these differences in the Middle-East are poorly understood. We studied to what extent difference in outcome, specifically 1-year mortality are attributable to demographic, baseline clinical differences at presentation, and management differences between female and male patients. Baseline characteristics, treatment patterns, and 1-year mortality of 7390 ACS patients in 65 hospitals in 6 Arabian Gulf countries were evaluated during 2008-2009, as part of the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2). Women were older (61.3±11.8 vs. 55.6±12.4; Pmanagement differences contributed to a worse outcome in women. Together these variables explained almost all mortality disparities. Differences between genders in mortality appeared to be largely explained by differences in prognostic variables and management patterns. However, the origin of the latter differences need further study.

    Rationale and objective Endothelial progenitor cells (EPCs) play a role in vascular repair, while circulating endothelial cells (CECs) are biomarkers of vascular damage and regeneration. Statins may promote EPC/CEC mobilization in the peripheral blood. We evaluated whether pre-procedural exposure to different lipid-lowering drugs (statins±ezetimibe) can acutely increase levels/activity of EPCs/CECs in patients with stable coronary artery disease (CAD). Methods In a planned sub-analysis of the Rosuvastatin For REduction Of Myocardial DamagE During Coronary AngioplastY (REMEDY) trial, 38 patients with stable CAD on chronic low-dose statin therapy were randomized, in a double-blind, placebo-controlled design, into 4 groups before PCI: i. placebo (n = 11); ii. atorvastatin (80 mg+40 mg, n = 9); iii. rosuvastatin (40 mg twice, n = 9); and iv. rosuvastatin (5 mg) and ezetimibe (10 mg) twice, (n = 9). At baseline and 24 h after treatment–before PCI–, patients underwent blinded analyses of EPCs [colony forming units-endothelial cells (CFU-ECs), endothelial colony-forming cells (ECFCs) and tubulization activity] and CECs in peripheral blood. Results We found no significant treatment effects on parameters investigated such as number of CECs [Median (IQR): i. 0(0), ii. 4.5(27), iii. 1.9(2.3), iv. 1.9(2.3)], CFU-ECs [Median (IQR): i. 27(11), ii. 19(31), iii. 47(36), iv. 30(98)], and ECFCs [Median (IQR): i. 86(84), ii. 7(84), iii. 8/(42.5), iv. 5(2)], as well as tubulization activity [total tubuli (well), Median (IQR): i. 19(7), ii. 5(4), iii. 25(13), iv. 15(24)]. Conclusions In this study, we found no evidence of acute changes in levels or activity of EPCs and CECs after high-dose lipid-lowering therapy in stable CAD patients. PMID:28394933

    In this study, we sought to investigate the serum levels of high sensitivity C-reactive protein (Hs-CRP), N-terminal pro-brain natriuretic peptide (NT proBNP), erythrocyte sedimentation rate, leukocyte, thyroid hormone and fibrinogen levels in patients with coronary slow flow phenomenon (CSFP). A total of 82 patients with angiographically proven normal coronary arteries and slow coronary flow in all three coronary vessels (45 males and 37 females, mean age 59±11 years) and 34 patients with normal coronary arteries and normal coronary flow (19 males and 15 females, mean age 56±10 years) with similar risk profiles were included in this cross-sectional observational study. Coronary flow rates of all patients and control subjects were documented by Thrombolysis In Myocardial Infarction (TIMI) frame count, serum level of Hs-CRP, NT proBNP, sedimentation, leukocyte, free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH) and fibrinogen levels were measured. Statistical analysis was performed using t test for independent samples, Chi-square test and Pearson correlation analysis. Hs-CRP (0.88±0.86 vs 0.36±0.35 mg/L, p=0.001) and NT proBNP (117.83±163.2 vs 47.33±30.6 ng/ml, p=0.01) were found to be significantly higher in patients with coronary slow flow compared with normal control group. There were no significant differences regarding thyroid hormones, fibrinogen, sedimentation rate and leukocyte count between two groups. The mean TIMI frame counts were positively correlated (r=0.454, p=0.001 and r=0.554, p=0.001, respectively) with plasma Hs-CRP levels and NT-proBNP levels. Hs-CRP and NT proBNP are significantly higher in patients with coronary slow flow compared with normal control group. Their increased levels are positively correlated with TIMI frame count.

    Risk evaluation of patients hospitalized with acute coronary syndrome (ACS) may contribute to their short-term prognosis improvement. The aim of this work was to develop a prediction index (score) for the risk assessment of 30-day death of ACS patients, using clinical and biological measurements at hospital admission. A sample of 6 Greek hospitals was selected, and almost all consecutive 2172 ACS patients from October 2003 to September 2004 were enrolled. Sociodemographic, biochemical, clinical, and lifestyle characteristics were recorded. Using as components age, systolic blood pressure, white blood cell count, creatine kinase-MB, and creatinine levels at the time of admission and the time between the onset of symptoms and presentation at hospital, a risk score (Greek Acute Coronary Syndrome score; range, 6-36) was developed and tested against in-hospital and 30-day outcome of the patients. The Greek Acute Coronary Syndrome score showed strong discriminating ability for in-hospital mortality (area under the receiver operating characteristic curve, 0.812; 95% confidence interval, 0.750-0.874; P period.

    Coronary flow reserve (CFR) assessment by transthoracic Doppler echocardiography has been found to be useful in subjects with suspected coronary artery disease. An important clinical question is whether such technique can be successfully applied in patients admitted to the coronary care unit with an acute coronary syndrome to detect a significant left anterior descending (LAD) disease. One hundred fifty-nine patients with acute coronary syndrome (93 patients with unstable angina, 66 with acute inferior or lateral myocardial infarction) were included in the present analysis. Patients underwent a high-dose dipyridamole stress (0.84 mg/kg) with combined assessment of CFR in the LAD and regional wall motion. Blood flow velocities were recorded in the mid-distal portion of the LAD using a digital ultrasonographic system and CFR was calculated as the ratio of hyperemia-induced peak diastolic velocity to resting peak diastolic flow velocity. All patients underwent coronary angiography and a significant LAD stenosis was classified for lumen narrowing > or = 70%. Adequate Doppler recordings in the LAD were obtained in 92% of patients. A contrast agent was used in the 39% of examinations. No major adverse reaction occurred in any patient. A receiving operating characteristic curve showed that a CFR value or = 70%. Early assessment of CFR by transthoracic Doppler echocardiography is feasible and safe and provides additional information to identify subjects with acute coronary syndrome and significant LAD stenosis.

    Significant insulin resistance and hyperinsulinemia has been observed to be associated with coronary heart disease in epidemiological studies, particularly so in Asian Indians. This study attempted to investigate if hyperinsulinemia accompanies acute cardiovascular events in Asian Indians, and that it is not a metabolic response to acute stress alone. To test this hypothesis, a case-control study was carried out in a tertiary referral hospital in northern India. Group I (n = 19), consisting of non-diabetic, non-hypertensive, non-obese patients presenting with first episode of acute coronary event (first episode of angina or myocardial infarction) were compared with non-diabetic, non-hypertensive, non-obese patients of group II (n = 21) presenting with non-cardiovascular emergencies (severe abdominal pain e.g. uncomplicated ureteric colic or non-specific intestinal colic. Blood was analysed for glycosylated haemoglobin, fructosamine and insulin levels within 24 hours of the acute event. Elevated serum fructosamine was observed in 11 (57.8%) subjects in group I and 9 (42.9%) in group II (p = NS). Glycosylated haemoglobin was 6.8 +/- 0.1 percent in group I versus 5.9 +/- 0.04 percent in group II (p < 0.01). Three out of 11 subjects in group I and 1/9 subjects in group II having elevated serum fructosamine level also had increased glycosylated haemoglobin level. Five (26.3%) subjects in group I and 2 (9.5%) in group II with elevated glycosylated haemoglobin level were excluded from the analysis as these patients might have been diabetic. Mean serum insulin values were significantly higher in group I (161.3 +/- 8.15 micro IU/mL and 17.5 +/- 1.9 micro IU/mL in groups I and II, respectively; p < 0.001). Eleven (57.8%) subjects in group I had insulin values above 100 uIU/ml. The present study indicates that significant hyperinsulinemia accompanies acute cardiovascular events and it is not an acute response to pain or stress hyperglycemia. Markedly high insulin levels

    Amabile, Nicolas; Malergue, Marie Christine; Achkouty, Guy; Czitrom, Daniel; Caussin, Christophe

    Unstable coronary artery disease is a more aggressive condition than stable coronary artery disease, accounting for the high incidence of major adverse cardiovascular events following acute coronary syndromes (ACS), which includes the need for iterative repeat revascularization. The aim of myocardial ischemia screening in post-ACS patients is to detect this unfavourable evolution (either on initial culprit or non culprit lesions) and to prevent any clinical complication. Although there is no strict recommendation in this particular situation, screening should be based on the use of stress imaging techniques. The optimal timing and frequency for testing will depend on the clinical characteristics of the patients and the coronary revascularization procedure features. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available A 35-year-old man of average build and a smoker, with a background of a psychiatric disorder, was brought by his neighbor to the emergency department after an hour of severe chest pain. Upon arrival at the hospital he had cardiac arrest, was resuscitated, and moved to the catheterization laboratory with inferior, posterior, and lateral myocardial infarction. Coronary angiography showed an unusual thrombosis in multiple coronary branches. Toxicology report showed high levels of amphetamines and benzodiazepines in the patient’s original blood sample. The patient was kept under ventilation for 18 days, with difficult recovery due to severe withdrawal manifestations, ventilation acquired pneumonia, and rhabdomyolysis inducing acute renal failure. The patient regained near normal left ventricular function after baseline severe regional and global dysfunction. We postulate a relationship between the use of amphetamines, potentiated by benzodiazepines, and occurrence of acute thrombosis of multiple major coronary arteries.

The trial was held in Chelyabinsk Regional Vascular Centre of specialized medical care for patients with acute coronary syndromes. Each of the three patients had similar reasons for systemic intravenous thrombolysis: hospitalization with ST-segment elevation myocardial infarction, unavailability of coronary interventions due to the X-ray operating room occupancy, high need for the reperfusion therapy in the setting of significant acute myocardial ischemia. In all the cases the pharmacologic reperfusion with recombinant protein comprising an amino acid sequence of staphylokinase was successful, hereafter percutaneous coronary interventions were performed.

    Full Text Available Current guidelines for the management of patients with acute coronary syndromes (ACSs focus on the electrocardiogram to divide patients into ST-elevation acute myocardial infarction (STEMI or non-ST-elevation acute myocardial infarction (NSTEMI/unstable angina (UA. Patients with STEMI in the earliest time will receive reperfusion therapy to destruct occlusive thrombus. An ST segment elevation is the ‘sine qua non’ for diagnosing acute total coronary occlusion causing transmural myocardial infarction. Left circumflex coronary artery (LCx occlusion is often categorized as NSTEMI because of the absence of significant ST-elevation on the 12 lead standard electrocardiogram. An ST segment elevation is presented in fewer than 50% of patients with LCx total occlusion, such that the reperfusion therapy is delayed. We reported a 77 years old woman whom being diagnosed with NSTEMI because a 12 lead electrocardiogram showed ST segment depression in lead V2-V5. On coronary angiography, we found a total occlusion in the LCx artery as the culprit lession.

    Health emergency service teams play an important role in the management of patients with acute coronary syndrome. They have to be educated, equipped, skilful and supported by the entire health care system. The role of county health center in the management of patients with acute coronary syndrome is illustrated in the article, based on the experience acquired at Medimurje County Health Center from Cakovec. The reformed Health Center activities including organization, coordination and linking of teams, population health monitoring at the local level, epidemiologic surveillance, education (active and passive, on both sides of college chair), joint diagnostic and other services, and quality control are discussed in detail. In contrast to a bureaucratic and formal one, a real and innovative reform should take account of necessary changes in the management and organization, not just in standards, rights and obligations. The management protocol for acute coronary syndrome patients is described: setting the main objective (acute coronary disease morbidity and mortality reduction), setting short-term and long-term specific goals, adoption of strategy based on the main objective (education, completion and particular programs pursuit, connecting, collaboration, quality assurance through clinical guidelines and protocols) and other elements, including dignity, leadership, teamwork, adoption and implementation of patient management protocols.

    Depression in patients with acute coronary syndromes (ACS) is common and associated with impaired cardiovascular prognosis in terms of cardiac mortality and new cardiovascular events. It remains unclear whether antidepressant treatment may reverse these effects. In this review, the literature is

    Acute Kidney Injury (AKI), a common complication of acute coronary syndromes (ACS), is associated with higher mortality and longer hospital stays. The role of cytokines and other mediators is unknown in AKI induced by an ACS (ACS-AKI), leading to several unanswered questions. The worsening of renal function is usually seen as a dichotomous phenomenon instead of a dynamic change, so evaluating changes of the renal function in time may provide valuable information in the ACS-AKI setting. The aim of this study was to explore inflammatory factors associated to de novo kidney injury induced by de novo cardiac injury secondary to ACS. One hundred four consecutive patients with ACS were initially included on the time of admission to the Coronary Unit of the Instituto Nacional de Cardiología in Mexico City, from February to May 2016, before any invasive procedure, imaging study, diuretic or anti-platelet therapy. White blood count, hemoglobin, NT-ProBNP, troponin I, C-reactive protein, albumin, glucose, Na + , K + , blood urea nitrogen (BUN), total cholesterol, HDL, LDL, triglycerides, creatinine (Cr), endothelin-1 (ET-1), leukotriene-B4, matrix metalloproteinase-2 and -9, tissue inhibitor of metalloproteinases-1, resolvin-D1 (RvD1), lipoxin-A4 (LXA4), interleukin-1β, -6, -8, and -10 were measured. We finally enrolled 78 patients, and subsequently we identified 15 patients with ACS-AKI. Correlations were obtained by a Spearman rank test. Low-rank regression, splines regressions, and also protein-protein/chemical interactions and pathways analyses networks were performed. Positive correlations of ΔCr were found with BUN, admission Cr, GRACE score, IL-1β, IL-6, NT-ProBNP and age, and negative correlations with systolic blood pressure, mean-BP, diastolic-BP and LxA4. In the regression analyses IL-10 and RvD1 had positive non-linear associations with ΔCr. ET-1 had also a positive association. Significant non-linear associations were seen with NT-proBNP, admission Cr, BUN

    We describe a case of coronary stenosis located in an unprotected left main coronary artery, treated primarily and electively with the placement of a coronary stent. As a function of the large mass of myocardium involved, this patient would be considered a classical candidate for direct surgery, because the inherent risk involved with conventional balloon angioplasty, mainly due to the eventual occurrence of acute closure during the procedure. Since the previsibility of the immediate results with the use of coronary stents was significantly improved, we propose this new therapeutic approach for this traditionally surgical case, that has been performed with success and without any complication. This strategy for the treatment of unprotected left main lesions with the elective placement of Palmaz-Schatz stents, has not yet been proposed or applied in our country, and may represent a new universe of indication of percutaneous treatment of coronary artery disease, no longer approaching the left main stem only in special or emergency situations, usually a result of complications of left main manipulation during angioplasty of the coronary system. The patient involved in this case did not show any contraindication for the treatment with conventional open heart surgery.

    To define the clinical and angiographic profile of patients undergoing to a 2nd or a 3rd coronary angioplaty (PTCA) for the treatment of restenosis, and assess the safety and efficacy of redilatation. Patients submitted to PTCA for a 1st (1stRE) or a 2nd (2ndRE) restenosis, from Jan/1980 through Dec/1993, were retrospectively identified, and compared to those undergoing to PTCA for de novo lesions (DN). A total of 5,736 underwent to dilatation of primary lesions, 610 of a 1stRE, and 64 of a 2ndRE. Patients with restenotic lesions had a higher prevalence of diabetes, smoking, history of prior infarction (1stRE e 2ndRE) and hyperlipidemia (2ndRE) as compared with primary lesions (p < 0.05). Besides patients with a 2ndRE had a higher incidence of left ventricular dysfunction, as compared to those with DN or a 1stRE (31.3% with EF < 45% in group 2ndRE, vs 19.8% and 23.1% in groups 1stRE and DN, respectively, p < 0.05). Primary success, infarct rate and mortality were similar in all groups, but emergency bypass surgery was significantly higher in the DN (2.1% vs 0.8% in 1stRE and 0% in 2ndRE, p < 0.05). Restenosis can be effectively treated by redilatation. Patients with clinical and angiographic features predisposing to further recurrence can be better treated with other interventions (i.e., coronary stents, bypass surgery).

    Diabetes is a stronger risk factor for acute coronary syndrome for women than men. We investigate whether behavioural and psychosocial factors contribute to the disparity in acute coronary syndrome risk and outcomes among women with diabetes relative to women without diabetes and men. Among 939 participants in the GENESIS-PRAXY cohort study of premature acute coronary syndrome (age ≤ 55 years), we compared the prevalence of traditional and non-traditional factors by sex and Type 2 diabetes status. In a case-only analysis, we used generalized logit models to investigate the influence of traditional and non-traditional factors on the interaction of sex and diabetes. In 287 women (14.3% with diabetes) and 652 men (10.4% with diabetes), women and men with diabetes showed a heavier burden of traditional cardiac risk factors compared with individuals without diabetes. Women with diabetes were more likely to be the primary earner and have more anxiety relative to women without diabetes, and reported worse perceived health compared with women without diabetes and men with diabetes. The interaction term for sex and diabetes (odds ratio (OR) 1.40, 95% confidence intervals (95% CI) 0.83-2.36) was diminished after additional adjustment for non-traditional factors (OR 1.12, 95% CI 0.54-2.32), but not traditional factors alone (OR 1.41, 95% CI 0.84-2.36). We observed trends toward a more adverse psychosocial profile among women with diabetes and incident acute coronary syndrome compared with women without diabetes and men with diabetes, which may explain the increased risk of acute coronary syndrome in women with diabetes and may also contribute to worse outcomes. © 2017 Diabetes UK.

    Currently available risk scores (RSs) were derived from populations with very few participants from China. We aimed to develop an RS based on data from patients with acute coronary syndrome in China and to compare its performance with the commonly promoted Global Registry of Acute Coronary Events (GRACE) RS. Clinical Pathways for Acute Coronary Syndromes-Phase 2 was a trial of a quality improvement intervention in China. Patients recruited from 75 hospitals from October 2007 to August 2010 were divided into training and validation sets based on immediate or delayed implementation. A Clinical Pathways for Acute Coronary Syndromes (CPACS) RS for in-hospital mortality was developed separately by gender, using the training set (6,790 patients). Discrimination and calibration of the CPACS RS and GRACE RS were compared on the validation set (3,801 patients). Although discrimination of the GRACE RS was acceptable, this was improved with the CPACS RS (c-statistic 0.82 vs 0.87, p = 0.012 for men; c-statistic 0.78 vs 0.85, p = 0.006 for women). The absolute bias was significantly lower with CPACS RS for both genders (7.6% vs 97.5% in men and 21.5% vs 77.2% in women), compared with the GRACE RS, which systematically overestimated risk. The CPACS RS underestimated risk in women, but only in those already above threshold levels currently used to define a clinical high-risk population. In conclusion, the GRACE RS substantially overestimates the risk of in-hospital death in patients presenting to the hospital with a suspected acute coronary syndrome in China. We have developed and independently validated a new RS utilizing data from Chinese patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Background. A variant form of angina pectoris (VAP is caused by coronary vessel spasm and occures in patients with and without varying degrees of obstructive coronary artery disease. Although the prognosis of VAP without significant organic stenosis is generally good, multivessel spasm is associated with a high risk of life-threatening abnormalities of rhythm and conduction.Patient and methods. We describe a patient who presented with prolonged chest pain, associated with hypotension, lost of consciousness, complete AV block and widespread ST segment elevations consistent with inferoanterior acute myocardial infarction. Urgent selective coronary angiography revealed spasms in right coronary artery and in left circumflex artery that were relieved by intracoronary injection of nitroglycerin. All coronary arteries were otherwise patient, without signs of atherosclerosis. The patient was treated with diltiazem and nitrates. She made a complete recovery and resumed her normal activities.Conclusions. Simultaneous multiple spasms of native coronary arteries represent a rare syndrome characterized by significantly higher incidence of potentially life-threatening arrhythmia. Less commonly, prolonged coronary spasm may mimic acute myocardial infarction. Modern management of acute coronary syndromes, including urgent coronarography, enables a prompt differentiation between prolonged coronary spasm and atherosclerotic coronary disease, warranting different treatment strategies. Medical treatment with nitrates and calcium channel blockers in most cases prevents recurrence of vasospasms and arrhythmias.

    Percutaneous transluminal angioplasty (PTA) is a non-operative therapeutic procedure to the dilation of stenosis or to the recanalization of occlusion in atherosclerotic arteries using of dilatation catheters. PTA was performed 37 times in 34 patients with arteriosclerotic for 1 year and 4 months from March, 1982 to June, 1983 at department of radiology, Klinikum Barmen/west Germany. The results were as follows; 1. The male to female ratio was 2 : 1 and peak age range was from 61 to 70. 2. The most common indication was clinical stage II b with 19 cases (51.3%). 3. PTA was performed most commonly in superficial femora artery in 25 cases (67.5%). 4. Acute major complication occurred in 2 cases (5.4%). PTA is a alternative or complementary therapeutic procedure to vascular surgery.

    This study was designed to determine whether coronary CT angiography (CTA) can detect features of plaque disruption in clinically stable patients and to compare lesion prevalence and features between stable patients and those with acute coronary syndrome (ACS). We retrospectively identified patients undergoing CTA, followed by invasive coronary angiography (ICA) within 60 days. Quantitative 3-vessel CTA lesion analysis was performed on all plaques ≥25% stenosis to assess total plaque volume, low attenuation plaque (LAP, disruption, including ulceration and intra-plaque dye penetration (IDP). ICA was employed as a reference standard for disruption. A total of 145 (94 ACS and 51 stable) patients were identified. By CTA, plaque disruption was evident in 77.7% of ACS cases. Although more common among those with ACS, CTA also detected plaque disruption in 37.3% of clinically stable patients (P disruption as determined by CTA. Though the prevalence of plaque disruption is less than patients with ACS, these findings support the concept that some clinically stable patients may harbour 'silent' disrupted plaques. These findings may have implications for detection of 'at risk' plaques and patients. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2015.

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

    An important subset of patients presenting with acute coronary syndrome (ACS) are found to have either normal coronaries (NCs) or non-obstructive coronary artery disease (NOCAD; lumen diameter narrowing characteristics and management strategies in this population in a real-world setting. The Acute Coronary Syndrome Israeli Survey (ACSIS) database was utilized to compare the characteristics and therapeutic approach for patients who underwent angiography for ACS and had either NC (n = 84; 2%), NOCAD (n = 79; 2%), or obstructive coronary artery disease (OCAD; n = 3523; 96%). Baseline characteristics were comparable, save for a younger age and a higher proportion of females in the NC group (P<.001 for both). Prior to admission, chronic anticoagulant therapy was more frequently used in the NC vs. the OCAD group (4.8% vs. 1.6%, respectively; P=.02). Recommended ACS evidence-based medications, both in-hospital and at discharge, were less frequently prescribed to patients with NC or NOCAD. In a real-world practice of ACS, underutilization of evidence-based medications in patients with NC or NOCAD was observed. Nonetheless, its prognostic significance is still unknown and must be explored in larger patient cohorts.

    Full Text Available Introduction: It has been argued in current studies that anabolic androgenic steroids (AAS are misused by a great number of bodybuilders and athletes. However, there is diverse and often conflicting scientific data on the cardiac and metabolic complications caused by the misuse of AAS. There may be various reasons for myocardial infarction (MI with normal coronary arteries. However, for the majority of patients, the exact cause is still unknown. Case report: A 32 year-old male who was complaining about severe chest pain was admitted to our emergency department. He had been taking methenolone acetate 200 mg weekly for a period of three years for body building. His cardiac markers were significantly elevated and electrocardiogram (ECG showed peaked T waves in all derivations, which did not show ST elevation or depression. Both right and left coronary artery systems were found to be completely normal as a result of the angiogram. Conclusion: The purpose of this study is to show that AAS induced MI can be encountered with normal coronary arteries during acute coronary syndrome.

    Full Text Available The receptor of advanced glycation end products (RAGE and its ligands are linked to the pathogenesis of coronary artery disease (CAD, and circulating soluble receptor of advanced glycation end products (sRAGE, reflecting the RAGE activity, is suggested as a potential biomarker. Elevated sRAGE levels are reported in relation to acute ischemia and this review focuses on the role of sRAGE as a biomarker for the acute coronary syndrome (ACS. The current studies demonstrated that sRAGE levels are elevated in relation to ACS, however during a very narrow time period, indicating that the time of sampling needs attention. Interestingly, activation of RAGE may influence the pathogenesis and reflection in sRAGE levels in acute and stable CAD differently.

    2012-11-01

    Cardiac complications following stroke or acute cerebrovascular accidents (CVA) are common; however, many of these complications are asymptomatic and do not cause adverse cardiac effects. Symptomatic events (such as acute myocardial infarction after CVA) rarely occur and are often the result of an underlying cardiac embolic source, such as a left ventricular thrombus. We report a case of spontaneous coronary thrombosis following thrombolytic therapy for acute CVA, and discuss the implication that an underlying systemic pro-thrombotic state may predispose individuals to thrombosis in disparate vascular beds.

    To compare the features of coronary computed tomography angiography (CCTA) imaging of the patients with acute total occlusion (ATO) of coronary artery with those of chronic total occlusion (CTO). CCTA of 26 patients with complete interruption of the coronary artery in CCTA and occlusion in conventional coronary angiography, were retrospectively analyzed. Discrimination between the ATO group (n = 11, patients with non ST elevation myocardial infarction or unstable angina) and the CTO group (n = 15, patients with stable angina or nonspecific symptom) was arbitrarily determined by clinical diagnosis. Lesion length, remodeling index (RI), plaque density measured by Hounsfield units (HU), plaque composition, percentage attenuation drop across the lesion, and presence of myocardial thinning were evaluated. Comparisons between the ATO and CTO groups revealed significantly shorter lesion length in the ATO group (0.40 cm vs. 1.87 cm, respectively; p = 0.001), and significantly higher RI (1.56 vs. 1.10, respectively; p = 0.004). Plaque density of the ATO group was lower (37.0 HU vs. 104.7 HU, respectively; p < 0.001) and non calcified plaque was frequently seen in the ATO group (72.7% vs. 26.7%, respectively; p = 0.02). Percentage attenuation drop across the lesion was lower for the ATO group (10.92% vs. 25.44%, respectively; p = 0.005). Myocardial thinning was exclusively observed in the CTO group (seven of 15 patients, p = 0.01). CCTA shows various statistically significant differences between the ATO and CTO groups.

    Purpose: Angioplasty effectively relieves coronary artery stenosis but is often followed by restenosis. Endovascular radiation (β or γ) at the time of angioplasty prevents restenosis in a large proportion of vessels in swine (short term) and humans (short and long term). Little information is available about the effects of this radiation exposure beyond the wall of the coronary arteries. Methods and Materials: Samples were obtained from 76 minipigs in the course of several experiments designed to evaluate endovascular brachytherapy: 76 of 114 coronary arteries and 6 of 12 iliac arteries were exposed to endovascular radiation from 32 P sources (35 Gy at 0.5 mm from the intima). Two-thirds of the vessels had angioplasty or stenting. The vessels were systematically examined either at 28 days or at 6 months after radiation. Results: We found an unexpected lesion: acute necrotizing vasculitis in arterioles located ≤2.05 mm from the target artery. It was characterized by fibrinoid necrosis of the wall, often associated with lymphocytic exudates or thrombosis. Based on the review of perpendicular sections of tissue samples, the arterioles had received between 6 and 40 Gy. This arteriolar vasculitis occurred at 28 days in samples from 51% of irradiated coronary arteries and 100% of irradiated iliac arteries. By 6 months, the incidence of acute vasculitis decreased to 24% around the coronary arteries. However, at that time, healing vasculitis was evident, often with luminal narrowing, in 46% of samples. Vasculitis was not seen in any of 44 samples from unirradiated vessels (0%) and had no relation to angioplasty, stenting, or their sequelae. This radiation-associated vasculitis in the swine resembles the localized lymphocytic vasculitis that we have reported in tissues of humans exposed to external radiation. On the other hand, it is quite different from the various types of systemic vasculitis that occur in nonirradiated humans. Conclusion: Endoarterial brachytherapy

    201 Tl stress myocardial scintigraphy was performed in convalescent patients with acute myocardial infarction, to evaluate the influence of stenosis and collateral circulation of coronary artery in acute phase, on myocardial salvage in chronic phase. In 14 cases of unsuccessful coronary revascularization (complete occlusion), a complete defect of thallium imaging in chronic phase was seen in only one case of four cases with good collateral circulation, while eight of 10 cases with poor collateral circulation. In 16 cases with collateral circulation, six cases showed a complete defect, although the target vessel had improved to less than 75% of stenosis. However, in cases of good collateral circulation, no case showed a complete defect when the target vessel had improved to less than 75% of stenosis. The myocardial salvage is quite possible (p<0.05), when the coronary angiography in acute phase showed the forward flow (99% or 90% of stenosis) before coronary revascularization and/or good collateral circulation (Rentrop 2deg or 3deg).

    Electrocardiography (ECG) offers some information that may be used to prognosticate acute type A aortic dissection (AAOD) for short- and long-term mortality. We retrospectively analyzed the electrocardiograms of patients with AAOD admitted from March 2004 to March 2015. The frequency of ECG findings and their prognostic value on hospital and follow-up mortality were investigated. Findings pertaining to coronary involvement and troponin level were also examined. A total of 120 men and 64 women were admitted. Acute ischemic changes were reported in 38.0%, whereas T inversion was the most common recorded abnormality, which occurred in 38.6%. Acute ST-elevation myocardial infarction was detected in 16.3%. Troponin increased in 36.6%; 21.9% of the patients underwent coronary angiography among which 70% were normal. Coronary involvement or troponin increase was not different in patients with acute ECG changes. During hospitalization, 45.7% of the patients died. In multivariate analyses, ST elevation in lead aVR was associated with higher hospital death (odds ratio, 5.30; 95% confidence interval, 1.09-25.73; P = .038), whereas QRS greater than 120 milliseconds was associated with long-term mortality (hazard ratio, 2.45; 95% confidence interval, 1.25-3.76; P = .006). Acute ischemic ECG changes are common in AAOD, and a completely normal ECG is infrequently encountered. Acute ECG changes were not associated with the increased troponin or the presence of coronary lesions in angiography. Published by Elsevier Inc.

    Full Text Available Abstract Background Despite continual improvements in the management of acute coronary syndromes, adherence to guideline-based medications remains suboptimal. We aim to improve adherence with guideline-based therapy following acute coronary syndrome using an existing service that is provided by specifically trained pharmacists, called a Home Medicines Review. We have made two minor adjustments to target the focus of the existing service including an acute coronary syndrome specific referral letter and a training package for the pharmacists providing the service. Methods/Design We will be conducting a randomized controlled trial to compare the directed home medicines review service to usual care following acute coronary syndromes. All patients aged 18 to 80 years and with a working diagnosis of acute coronary syndrome, who are admitted to two public, acute care hospitals, will be screened for enrolment into the trial. Exclusion criteria will include: not being discharged home, documented cognitive decline, non-Medicare eligibility, and presence of a terminal malignancy. Randomization concealment and sequence generation will occur through a centrally-monitored computer program. Patients randomized to the control group will receive usual post-discharge care. Patients randomized to receive the intervention will be offered usual post-discharge care and a directed home medicines review at two months post-discharge. The study endpoints will be six and twelve months post-discharge. The primary outcome will be the proportion of patients who are adherent to a complete, guideline-based medication regimen. Secondary outcomes will include hospital readmission rates, length of hospital stays, changes in quality of life, smoking cessation rates, cardiac rehabilitation completion rates, and mortality. Discussion As the trial is closely based on an existing service, any improvements observed should be highly translatable into regular practice. Possible

    Full Text Available Background: Acute Coronary Syndrome (ACS is a shift manifestations pattern of ischemic myocardium. Revascularization either with Primary Percutaneous Coronary Intervention (PCI or pharmacological therapy is an optional treatment for ST Elevation Acute Coronary Syndrome (STEACS patients. The aim of the study was to compare the functional capacity using six-minute walking test on STEACS patients who underwent Primary PCI or pharmacological therapy. Methods: A cross sectional study was conducted from September to October 2012 to 35 STEACS patients who were treated after two years. The samples were obtained from the list of patients at Dr. Hasan Sadikin General Hospital. Inclusion criteria consisted of patients diagnosed as STEACS, cooperative and not experiencing cognitive disturbance. The exclusion criteria were STEACS patients with unstable angina or myocardial infarct in the last month, stable exertional angina, and pregnant women. The patients underwent 6 minutes walking test,VO2max was measured using theCalahin and Cooper formula, then Metabolic Equation Task (METs was calculated. Data were analyzed by unpaired T-test. Results: There were 19 Primary PCI and 16 pharmacological therapy patients. The average of age between the two groups was distributed evenly. Most of the STEACS patients were male, had a college/academic degree and were retired. Patients treated with pharmacological therapy had higher average of VO2 max and METs than patients with Primary PCI. There was no significantly differences of METs between those groups (p>0.05 Conclusions: There were no significantly differences of functional capacity in STEACS patients treated with Primary PCI or Pharmacological therapy.

    A 41-year-old man collapsed after lifting weights at a gym. Following admission to the emergency department, a 64-slice cardiac computed tomography (CT) revealed a Stanford Type A aortic dissection arising from a previous coarctation repair. Multiphasic reconstructions demonstrated an unstable, highly mobile aortic dissection flap that extended proximally to involve the right coronary artery ostium. Our case is an example of the application of electrocardiogram-gated cardiac CT in directly visualizing involvement of the coronary ostia in acute aortic dissection, which may influence surgical management.

    The burden of cardiovascular diseases is anticipated to rise in developing countries. We sought to describe the epidemiology, management, and clinical outcomes of patients hospitalized with acute coronary syndromes (ACS) in three countries in western North Africa. Adult patients hospitalized with a diagnosis of ACS were enrolled in the prospective ACute Coronary Events - a multinational Survey of current management Strategies (ACCESS) registry over a 13-month period (January 2007 to January 2008). We report on patients enrolled at sites in Algeria, Morocco and Tunisia. A standardized form was used to collect data on patient characteristics, treatments and outcomes. A total of 1687 patients with confirmed ACS were enrolled (median age 59 [interquartile range 52, 68] years; 76% men), 59% with ST-elevation myocardial infarction (STEMI) and 41% with non-ST-elevation ACS (NSTE-ACS). During hospitalization, most patients received aspirin (96%) and a statin (90%), 83% received a beta-blocker and 74% an angiotensin-converting enzyme inhibitor. Among eligible STEMI patients, 42% (419/989) did not receive fibrinolysis or undergo percutaneous coronary intervention. All-cause death at 12 months was 8.1% and did not differ significantly between patients with STEMI or NSTE-ACS (8.3% vs 7.7%, respectively; Log-rank test P=0.82). Clinical factors associated with higher risk of death at 12 months included cardiac arrest, cardiogenic shock, bleeding episodes and diabetes, while percutaneous coronary intervention and male sex were associated with lower risk. In this observational study of ACS patients from three Maghreb countries, the use of evidence-based pharmacological therapies for ACS was quite high; however, 42% of the patients with STEMI were not given any form of reperfusion therapy.

    Full Text Available Background: The radial access provides a lower risk of bleeding and vascular complications related to the puncture site in comparison to the femoral access. Recent studies have suggested a reduction in mortality associated with the radial access in patients with acute myocardial infarction undergoing percutaneous coronary intervention. Objective: To compare the occurrence of adverse cardiovascular ischemic and hemorrhagic events in patients undergoing primary angioplasty according to the type of arterial access route. Methods: From August 2010 to December 2011, 588 patients undergoing primary percutaneous coronary intervention during acute ST-segment elevation myocardial infarction were assessed; they were recruited from 47 centers participating in the ACCEPT registry. Patients were grouped and compared according to the arterial access used for the procedure. Results: The mean age was 61.8 years; 75% were males and 24% had diabetes mellitus. There was no difference between groups as regards the procedure success rate, as well as regards the occurrence of death, reinfarction, or stroke at six months of follow-up. Severe bleeding was reported in 1.1% of the sample analyzed, with no statistical difference related to the access used. Conclusions: The femoral and radial accesses are equally safe and effective for the performance of primary percutaneous coronary intervention. The low rate of cardiovascular events and of hemorrhagic complications reflects the quality of the participating centers and the operators expertise with the use of both techniques.

    Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

    to study rate and type of life-threatening complications (LC) in patients with ST-Elevation (STE) Acute Coronary Syndrome (ACS) and their relation to implementation of reperfusion measures. Database of the Federal Register of patients with ACS (FRACS) which functioned from 01/01/2009 to 01/01/2014 contains information on 212304 patients with verified diagnosis of ACS. From this pool using random number generator we selected a cohort comprising 10348 patients with STEACS (60% men, mean age 63.5+/-0.1 clinical systolic and diastolic arterial pressure [AP] 135.2+/-0.3 and 81.9+/-0.2 mm Hg, respectively). Killip class was used for determination of degree of acute heart failure. Most frequent forms of LC were heart rhythm disturbances (6.2%) and cardiogenic shock (5.4%). Patients subjected to percutaneous coronary intervention (PCI) including those in whom pharmacoinvasive approach was used had less LC and lower hospital mortality than patients who received only thrombolytic therapy (TLT). Reperfusion measures were administered mostly to patients with class I-II acute heart failure. Hospital mortality was highest (9.47%) among patients not subjected to reperfusion measures and lowest (1.09%) among patients treated with PCI+TLT. FRACS assesses LC in patients with STEACS in the context of implemented reperfusion measures. Data of FRACS can be used by the health service authorities for improvement of medical aid to patients with STEACS.

    Hypertension affects one billion people worldwide and is an independent risk factor for death after acute coronary syndrome (ACS). The aim of this study was to examine the prevalence and medical treatment of hypertension among 1,301 ACS patients enrolled into the Chinese registry of acute coronary events (CRACE) trial. Analyses were performed by gender, with both genders combined and according to international practice. Multivariable models identified factors associated with use of different classes of antihypertensive medication, and examined the correlation between hypertension and gender with mortality. The use of angiotensin‑converting enzyme inhibitors (ACEI), β-blockers, calcium channel blockers (CCBs) and diuretics increased in both genders during management of presenting ACS. Hypertensive men were more likely to have been receiving β-blockers when they were discharged (77.2%) than women (69.2%). Hypertensive women were more likely to have received diuretics when they were discharged (28.4%) than men (22%). ACEI use increased by ~60% (absolute increase) in both women and men as a result of ACS treatment, but remained similar between the genders, and the same phenomenon was observed in the use of CCBs. Moreover, hypertensive women were less likely to receive evidence‑based medication to treat their acute coronary event than men (for women and men, respectively: β-blocker, 69.2 vs. 77.2%; ACEI, 85.8 vs. 87.5%). Hypertension is more prevalent in women than in men with ACS, and its medical management varies with gender, but it has a similar association with mortality in both genders. Opportunities exist to improve medical therapy and outcomes for women with hypertension.

    Full Text Available Background. Acute coronary syndrome (ACS can complicate acute ischemic stroke, causing significant morbidity and mortality. To date, literatures that describe poststroke acute coronary syndrome and its morbidity and mortality burden are lacking. Methods. This is a single center, retrospective study where clinical characteristics, cardiac evaluation, and management of patients with suspected poststroke ACS were compared and analyzed for their association with inpatient mortality and 1-year all-cause mortality. Results. Of the 82 patients, 32% had chest pain and 88% had ischemic ECG changes; mean peak troponin level was 18, and mean ejection fraction was 40%. The medical management group had older individuals (73 versus 67 years, p<0.05, lower mean peak troponin levels (12 versus 49, p<0.05, and lower mean length of stay (12 versus 25 days, p<0.05 compared to those who underwent stent or CABG. Troponin levels were significantly associated with 1-year all-cause mortality. Conclusion. Age and troponin level appear to play a role in the current clinical decision making for patient with suspected poststroke ACS. Troponin level appears to significantly correlate with 1-year all-cause mortality. In the management of poststroke acute coronary syndrome, optimal medical therapy had similar inpatient and all-cause mortality compared to PCI and/or CABG.

    Full Text Available Troponin gives excellent accuracy in the identification of myocardial necrosis, however, it may elevate also in a series of non-atherosclerotic heart diseases. We report the case of a 58-year-old woman with diabetic ketoacidosis (DKA. She had markedly increased levels (90 fold of cardiac biomarkers (troponin I and CK-MB and initial electrocardiography changes compatible with myocardial infarction. She had normal a coronary angiogram. This case shows that nonspecific myocardial injury may occur in DKA with the findings mimicking myocardial infarction including increased level of cardiac biomarkers and electrocardiography changes.

    Acute myocardial infarction is the leading cause of non-communicable deaths worldwide. Its diagnosis is a highly complex task, for which modelling through automated methods has been attempted. A systematic review of the literature was performed on diagnostic tests that applied intelligent systems tools in the diagnosis of acute coronary syndromes. A systematic review of the literature is presented using Medline, Embase, Scopus, IEEE/IET Electronic Library, ISI Web of Science, Latindex and LILACS databases for articles that include the diagnostic evaluation of acute coronary syndromes using intelligent systems. The review process was conducted independently by 2 reviewers, and discrepancies were resolved through the participation of a third person. The operational characteristics of the studied tools were extracted. A total of 35 references met the inclusion criteria. In 22 (62.8%) cases, neural networks were used. In five studies, the performances of several intelligent systems tools were compared. Thirteen studies sought to perform diagnoses of all acute coronary syndromes, and in 22, only infarctions were studied. In 21 cases, clinical and electrocardiographic aspects were used as input data, and in 10, only electrocardiographic data were used. Most intelligent systems use the clinical context as a reference standard. High rates of diagnostic accuracy were found with better performance using neural networks and support vector machines, compared with statistical tools of pattern recognition and decision trees. Extensive evidence was found that shows that using intelligent systems tools achieves a greater degree of accuracy than some clinical algorithms or scales and, thus, should be considered appropriate tools for supporting diagnostic decisions of acute coronary syndromes.

    In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

    Acute Coronary Syndrome (ACS), is a serious threat to people's health, and life, and in recent years, the incidence has increased yearly. This study was to propose the hypothesis of "endogenous collateral wind" based on the patho-mechanism of thrombogenesis complicated by ruptured plaque on ACS, and the theory of traditional Chinese medicine. Through successful coronary angiography (CAG), and intravascular ultrasound (IVUS), patients with coronary artery disease were made the differential diagnosis such as blood stasis, blood stasis due to phlegm obstruction, and endogenous collateral wind. The levels of plasma inflammatory marker were measured to study on the characteristics of "endogenous collateral wind". Luo heng dripping pills with promoting blood circulation to expel wind-evil, and remove wetness were made based on the hypothesis of "endogenous collateral wind" on ACS. Patients with unstable angina were randomly divided into 3, groups based on therapeutic methods: conventional therapy group, Luo Heng dripping pills group and Tongxinluo caps. Differences among groups were compared. There were great changes in number and degree of coronary arteriostenosis confirmed by CAG, the types of ACC/AHA lesion and Levin lesion confirmed by CAG, remodeling index, positive or negative remodeling percentage measured by IVUS, the plasma levels of plasma inflammatory marker measured by ELLSA in the patients with endogenous collateral wind, compared with patients with blood stasis and blood stasis due to phlegm obstruction. The total effective rate of improved angina in Luo Heng dripping pills group was significantly higher than those in other two groups. The levels of plasma inflammatory marker were significantly lower in Luo Heng dripping pills group. There were some pathological basis which were found about the hypothesis of "endogenous collateral wind" on acute coronary syndrome. It provided evidences for patients with coronary artery disease treated by medicines with

    Twenty seven patients with femoral artery occlusion were treated by transluminal Nd:YAG laser angioplasty, in 16 patients the procedure was combined with intraarterial infusion of rTPA (actilyse-Boehringer Ing). In 5 out of 11 patients from the initial group recanalization was not successful. In 16 patients from the rTPA group satisfactory immediate results were achieved in all cases. In long time observations ranging from 9 to 24 months all patients remained free from symptoms, although in 4 of them angiography and Doppler ultrasound examination reveal no flow in the femoral artery. In the remaining 12 patients (75%), the previously occluded artery is patent. No complications of laser angioplasty nor intraarterial infusion of rTPA were noted in this series.

    Depression has been related to the occurrence of cardiovascular diseases, and also appears to increase the risk of death from coronary artery disease. The presence of depression after the occurrence of an acute coronary syndrome (ACS) and its relationship with socioeconomic factors has not been studied in Colombia. To describe the frequency of depression and associated factors in patients hospitalized with an ACS. A cross-sectional study was carried out between April and May 2008 in three coronary care units in Santa Marta, Colombia. The presence of depression was evaluated with the Beck Depression Inventory (BDI). Depression was considered to be present if BDI was equal or greater than 10. The relationship between the presence of depression and demographic, clinic and laboratory characteristics was analyzed. A BDI score ≥10 (any degree of depression) was seen in 21 (63.64%) of the patients. In 9 out of 10 (91.66%) patients without stable income had depression in contrast to 12 out of 23 (57.14%) with stable income (P=.037). Depression was found in in 8 of the 8 (100%) patients with electrocardiographic pathological T wave inversion, in contrast to 13 out of the 25 (52%) without changes in T wave (P=.014). Depression was detected in 17 of 22 (77.27%) patients who smoked cigarettes versus 4 of 11 (36.36%) of patients who have never smoked (P=.021). Depressive symptoms are significantly present in patients suffering an acute coronary syndrome. Unemployment, pathological T wave inversion, and smoking seem to be associated with the presence of depressive symptoms after an acute coronary event.

    Pre-hospitalization medication such as aspirin and nitrates has been shown to affect the mode of presentation in acute coronary syndrome (ACS). However, it is not formally assessed whether other cardiovascular medications may be contributed to the differences in the mode of presentation, especially in relation to coronary risk factors. We conducted a registration study of patients (M/F 850/323) with either ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) or unstable angina (UA), and examined the differences in the mode of presentation, pre-hospitalization medication, and coronary risk factors. The ratio of the incidence of STEMI and NSTEMI/UA was significantly reduced in patients having pre-hospitalization medication with aspirin, nitrates or statins, but not with other medications such as beta-blockers in multivariate analysis. Pre-hospitalization medication with aspirin and nitrates was significantly associated with the same reduction of the ratio in patients with male gender, hypertension, diabetes mellitus and a history of coronary artery disease. However, in patients who smoked, were obese and hypercholesterolemic, pre-hospitalization medication with nitrates was significantly associated with the reduced ratio. The ratio was significantly low in patients with males and hypercholesterolemia treated with statins before admission. Depending on their coronary risk factors, pre-hospitalization medication with aspirin, nitrates or statins was associated with a different presentation and evolution of ACS.

    AIM: Escitalopram may prevent depression following acute coronary syndrome. We sought to estimate the effects of escitalopram on self-reported health and to identify subgroups with higher efficacy. METHODS: This is a secondary analysis of a 12-month double-blind clinical trial randomizing non......-depressed acute coronary syndrome patients to escitalopram (n = 120) or matching placebo (n = 120). The main outcomes were mean scores on Short Form 36 Health Survey (SF-36) domains, and diagnosis of depression was adjusted for baseline SF-36 scores. RESULTS: Escitalopram did not yield different SF-36...... trajectories on any scale compared with placebo (P > 0.28). Efficacy of escitalopram may have been better among those scoring at least the normative score on general health perceptions (hazard ratio (HR) for depression 0.17 (95% confidence interval 0.02-1.42) ) or social functioning (HR = 0.12 (0...

    The aim of this study was to revisit findings from previous studies reporting that pet ownership improves outcome following an admission for acute coronary syndrome (ACS). Four hundred and twenty-four patients admitted to a cardiac unit with an ACS completed questions regarding pet ownership in hospital. Rates of cardiac death and readmission were assessed 1 year following hospitalization. Pet owners were more likely to experience a death or readmission following their hospitalization, after controlling for key psychosocial and medical covariates. When dog and cat owners were considered separately, cat ownership was significantly associated with increased risk of death or readmission. In this independent study, pet ownership at baseline, and cat ownership in particular, was associated with increased cardiac morbidity and mortality in the year following an admission for an acute coronary syndrome, a finding contrary to previous reports.

    Full Text Available The objective was to determine the rate of potential drug-drug interactions in prescriptions for elderly diagnosed with Acute Coronary Syndrome in a teaching hospital. This is an exploratory, descriptive study that analyzed 607 prescriptions through databases to identify and classify the interactions based on intensity (major, moderate or minor, the mechanism (pharmacokinetic or pharmacodynamics and documentation relevance. We detected 10,162 drug-drug interactions, distributed in 554 types of different combinations within the prescribed drugs, and 99% of prescriptions presented at least one and a maximum of 53 interactions; highlighting the prevalence of major and moderates ones. There was a correlation between the number of drug-drug interactions and the number of prescribed drugs and the hospitalization time. This study contributes for the delimitation of a prevalence pattern in drug-drug interactions in prescriptions for Acute Coronary Syndrome, besides subsidizing the importance of the effective implementation of the Clinical Pharmacy in teaching hospitals.

    Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome. Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables. The patients underwent coronary angiography to determine the extent of the disease. A significant level was defined as >70% stenosis in any major epicardial artery or >50% stenosis in the left main coronary artery. SPSS 19 was used for statistical analysis. Results: Both the indices showed good predictive value in identifying the extent of the disease. A Thrombolysis In Myocardial Infarction score >4 and Global Registry of Acute Coronary Events score >133 was significantly associated with 3vessel disease and left main disease, while for the former score <4 and latter score <133 was associated with normal or non-obstructive coronary disease (p<0.01). On comparison of the two risk scores, the discriminatory accuracy of the latter was significantly superior to the former in predicting 2vessel, 3vessel and left main diseases (p<0.05). Conclusion: Although both the indices were helpful in predicting the extent of the disease, the Global Registry showed better performance and was more strongly associated with multi-vessel and left main coronary artery disease.

    Full Text Available Type 2 diabetes and prediabetes are established risk factors for atherosclerosis. The aim of this study was to evaluate the atherosclerotic plaque burden in the carotid arteries of patients with acute coronary syndrome according to their glycemic status.Patients with acute coronary syndrome and no previous history of type 2 diabetes were consecutively included in the study. Glucose metabolism was evaluated with fasting glucose in plasma, HbA1c and a standard two-hour oral glucose tolerance test. Atherosclerotic plaque in the carotid arteries was evaluated with a standardized ultrasound examination where total plaque area was measured and patients classified as having no plaque or a significant plaque formation.A total of 245 acute coronary syndrome patients (male 78%, 64 years (SD: 10.9 were included. The proportion diagnosed with normal glucose metabolism, prediabetes and type 2 diabetes was 28.6%, 64.1% and 7.3%, respectively. A significant atherosclerotic plaque was found in 48.5%, 66.9% and 72.2% of patients with normal glucose metabolism, prediabetes and type 2 diabetes, respectively. An incremental increase in total plaque area was found from normal glucose metabolism to prediabetes (25.5% and from normal glucose metabolism to type 2 diabetes (35.9% (p = 0.04. When adjusted for conventional cardiovascular risk factors the OR of having significant atherosclerotic plaque in the carotid arteries was 2.17 (95% CI 1.15-4.15 for patients with newly diagnosed dysglycemia compared to patients with normal glucose metabolism. When additionally adjusted for the 2-hour plasma glucose after glucose loading (2hPG the OR attenuated to 1.77 (95% CI 0.83-3.84.Newly detected dysglycemia is an independent predictor of significant atherosclerotic plaque in the carotid arteries with oral glucose tolerance test as a major determinant of carotid plaque burden in this group of individuals with acute coronary syndrome.

    There is progressive interest worldwide in spontaneous coronary artery dissection (SCAD). To identify a SCAD cohort and compare risk factors, presentation, and management outcomes compared to acute coronary syndrome (ACS) matched controls. Retrospective analysis was performed from 2000 to 2015. Clinical data included a neuropsychiatric history, with management and clinical outcomes assessed at 12 months. Patients were matched on a 1:3 case-control basis according to type of ACS. Twenty-two SCAD patients were matched to 66 controls by ACS type (ST-elevation myocardial infarction 45%, Non-ST-elevation myocardial infarction 41%, unstable angina 14%). The SCAD group were more likely female (77.3% vs 19.7%, P SCAD patients had a high prevalence of anxiety, depression or previous neuropsychiatric history (52.4% SCAD vs 1.5% ACS, P SCAD patients (13.6% SCAD vs 83.3% ACS, P SCAD vs 27.3% ACS P = NS). SCAD affects young females with a paucity of cardiovascular risk factors. The major risk factor for SCAD was a history of anxiety, depression, or neuropsychiatric illness. A conservative approach to SCAD revascularization led to similar MACCE when compared to ACS controls undergoing guideline revascularization at 12 months. © 2017, Wiley Periodicals, Inc.

    Full Text Available Introduction. Patients with non-ST elevation acute coronary syndromes (NSTE-ACS are sometimes severely hemodynamicly compromised. Urgent coronary angiography should be performed in these patients in percutaneous coronary intervention (PCI centers according to the ESC NSTE-ACS guidelines to determine suitabilty for percutaneous or surgical revascularization. Case report. We reported a 62-year-old male with chest pain admitted to the Coronary Care Unit. ST segment depression of 2 mm in leads I, L and V4-6 was revealed at electrocardiogram. After following 6 hours the patient had chest pain and signs of cardiogenic shock despite of the therapy. Chest x-ray showed pulmonary edema. Echocardiographic examination showed dyskinetic medium and apical segments of septum. The patient underwent coronary angiography immediately which revealed 75% stenosis of the left main coronary artery with thrombus. The use of a GPIIb/III inhibitor-tirofiban and stent implantation resulted in TIMI III flow. After that the patient had no chest pain and acute heart failure subsided in the following days Echocardiography done at the fourth day from PCI showed only hypokinesis medium and apical segment of septum. The patient was discharged at day 11 from admission in a stable condition. Conclusion. Stenting of left main coronary artery stenosis in patients with cardiogenic shock and non- ST segment elevation acute coronary syndromes may be a life saving procedure.

    To assess time trends in the use of main drug classes for secondary prevention, during hospitalization and at hospital discharge, following an acute coronary syndrome, in Portugal, using a systematic review. We searched PubMed, from inception until 2012, to identify studies reporting the proportion of acute coronary syndrome patients treated with main pharmacological therapy. We used linear regression to quantify the annual variation in use of drugs, adjusting for the proportion of men in the sample and patients' mean age, and including a quadratic term of data collection year when relevant. In 25 eligible studies, including patients treated from 1993 to 2009, we observed an increase in the prescription of pharmacological treatments at hospital discharge. Extrapolating from these data, and assuming a mean patient age of 65 years and 70% of men, we estimate that in 2008, 95% of patients would have been discharged with aspirin, 92% with clopidogrel, 82% with β-blockers, 80% with angiotensin-converting enzyme inhibitors and 91% with statins. Treatment during hospitalization followed a similar pattern, except for a steeper increase in angiotensin-converting enzyme inhibitors use, which was initially lower, but reached similar levels to those at discharge in recent years. In Portugal, there was an increase in the use of recommended pharmacological therapy for secondary prevention after an acute coronary syndrome over the last 15 years, during hospitalization and at hospital discharge.

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    The impact of sex on clinical outcomes of percutaneous coronary intervention and coronary artery bypass graft for patients with multivessel coronary disease and unprotected left main disease could be dissimilar between Western and Asian populations. To assess clinical outcomes after percutaneous coronary intervention or coronary artery bypass graft in women and men with multivessel coronary disease and unprotected left main disease, a pooled analysis (n=3280) was performed using the patient-level data from 3 large randomized trials: SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery), PRECOMBAT (Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease), and BEST (Bypass Surgery and Everolimus-Eluting Stent Implantation in the Treatment of Patients with Multivessel Coronary Artery Disease) trials. The primary end point was all-cause death. Of 3280 patients, 794 patients (24.2%) were women. The median follow-up period was 1806 days (1611-1837 days). In women, a high heterogeneity of the treatment effect among the 3 trials was found for all-cause death ( I 2 >50%), whereas in men, it was consistent across the 3 trials. In the Western trial (SYNTAX), female sex favored coronary artery bypass graft compared with percutaneous coronary intervention (hazard ratio (percutaneous coronary intervention) 2.213; 95% confidence interval, 1.242-3.943; P =0.007), whereas in the Asian women (PRECOMBAT and BEST), the treatment effect was neutral between both strategies. Sex interaction with treatment strategy was evident in the Western trial ( P interaction =0.019) but not in the Asian trials (PRECOMBAT P interaction =0.469 and BEST P interaction =0.472; I 2 =58%). The present meta-analysis suggested the presence of the heterogeneous sex-treatment interaction across Asian and Western trials. Considering the ongoing globalization of our medical practice, the heterogeneity of the sex-treatment interaction needs to be

    We investigated the use of a 3-hr treatment with hemodiafiltration, initiated soon after emergency or urgent coronary angiography in acute coronary syndrome (ACS) patients with associated severe renal and cardiac dysfunction. Patients with ACS and severe combined renal and cardiac dysfunction have a particularly high mortality risk. In them, the ideal strategy to both optimize treatment of coronary disease and minimize renal injury risk is currently unknown. This was an interventional study. ACS patients (STEMI and NSTEMI) with associated severe renal (eGFR ≤30 ml/min/1.73 m(2) ) and cardiac (LVEF ≤40%) dysfunction, admitted at La Spezia Hospital renal replacement therapy during hospitalization (7% vs. 27%; P = 0.04). Our pilot study suggests that, in ACS patients with severe renal and cardiac insufficiency, treatment with an aggressive prophylactic hemodiafiltration session after urgent or emergency coronary angiography seems to be associated with a relevant improvement in survival. © 2014 Wiley Periodicals, Inc.

We tested whether MBL and elevated viral and bacterial antibodies were risk factors for acute coronary events. Controlled cohort study. A total of 354 patients with unstable angina pectoris (UA) or acute myocardial infarction (AMI) were compared with 334 paired controls. Enterovirus titres were associated with increased risk of UA (odds ratio 10.04, P<0.001) and AMI (odds ratio 3.18, P=0.003), but titres did not correlate with either MBL concentration or genotype. Chlamydia pneumoniae heat shock protein 60 IgG concentrations were also associated with increased risk of UA (odds ratio 1.63, P=0.049). Compared to asymptomatic controls, patients had lower complement C3 serum concentrations (P<0.001), higher MBL serum concentration, and more frequently had MBL genotypes that determined high MBL levels (P<0.001). High MBL genotypes had odds ratios of 1.16 (P=0.010) for UA and 1.12 (P=0.007) for AMI. The elevation of MBL concentrations in the acute phase correlated with MBL concentrations after recovery (r=0.85, P<0.001). Elevated microbial titres, indicating an on-going inflammation, were associated with cardiovascular events. MBL might have a dual role both decreasing susceptibility to infections and increasing the risk of acute coronary syndromes.

    To assess the association of leisure-time exercise and television (TV) viewing, a sedentary marker, with acute coronary syndrome (ACS) in Albania, a transitional country in Southeast Europe. A population-based case-control study was conducted among Tirana residents in 2003-2006. Information on leisure-time exercise (transformed into kilocalories of energy expenditure) and daily hours of TV viewing was obtained by interviewer-administered questionnaire. 460 non-fatal ACS patients (368 men, 92 women) and 628 coronary heart disease-free controls (413 men, 215 women) were studied. Adjusted for socio-demographic characteristics, conventional coronary risk factors and leisure-time exercise, TV viewing was associated with ACS in women (OR=1.66, 95%CI=1.12-2.46 per hour/day viewing), but not in men (OR=0.93, 95%CI=0.81-1.07; P for sex-interaction=0.02). A low level of leisure-time exercise (adjusted also for TV viewing) was associated with ACS similarly in men and women (pooled sexes OR=2.03, 95%CI=1.29-3.22 for bottom vs top tertile of energy expenditure). Leisure-time inactivity is confirmed as an important risk factor for ACS also in Southeastern Europe. TV viewing may be an informative coronary risk marker in transitional societies, especially in women.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Full Text Available Aortic dissection is a critical condition requiring immediate assessment and management. Clinical presentation is commonly associated with severe chest pain and high blood pressure. However, misdiagnosis is frequent because of various features. We presented a case of 51-year-old woman who complained of dyspnea for 3 d after she experienced back pain for one week. She was presented with severe respiration distress with impending respiration failure on arrival to our hospital. Her chest X-ray showed cardiomegaly with acute pulmonary edema. The laboratory data revealed elevated cardiac enzyme and electrocardiography demonstrated sinus tachycardia. She was hospitalized under the initial diagnosis of acute coronary syndrome. The patient remained hemodynamically stable, and experienced one episode of chest discomfort. After electrocardiography, she was found with bigeminy ventricular premature beats without ST-T change. Follow-up cardiac enzyme demonstrated progressive declined. Cardiac catheterization was performed on the third day of admission, and coronary angiography revealed large intimal flap on aortic root with bilateral coronary artery involvement. Surgical management was arranged after immediate chest computed tomography study.

    Full Text Available Objective: Dendritic cells (DCs activation is important in atherosclerosis and coronary heart disease, but the mechanisms regulating activation of dendritic cells remain largely unclear. The aim of this study was to evaluate the effect of transcription factor Kruppel-like factor 2 (KLF2 in the proinflammatory activation of DCs in acute coronary syndrome. Methods and Results: In this study, the expression of CD80 and KLF2 was detected in DCs in normal health controls, patients with stable angina (SA, and acute coronary syndrome (ACS. Our study found that compared with normal control and SA, KLF2 expression in DCs is reduced in patients with ACS. Moreover, the surface expression of CD80 was increased in ACS. In vitro experiment, we found that ox-LDL could increase CD80 expression and decrease KLF2 expression. Furthermore, down-regulated KLF2 could in turn increase CD80 expression via NF-κB pathway. Conclusions: These observations identify KLF2 as a novel negative regulator of DC function and it may play an essential role in DC activation in ACS.

    Personalised care planning is argued for but there is a need to know more about what the plans actually contain. To describe the content of person-centred health, plans documented at three healthcare levels for patients with acute coronary syndrome. Patients with acute coronary syndrome aged under 75 years and admitted to two coronary care units at a university hospital were enrolled in the study. This retrospective descriptive study documented 89 person-centred health plans at three healthcare levels: hospital, outpatient and primary care. In total, 267 health plans were reviewed and a quantitative content analysis conducted. The health plans included commonly formulated goals, patients' own resources and support needed. The health plan goals were divided into three categories: lifestyle changes, illness management and relational activities. The most frequently reported goal for better health was increased physical activity, followed by social life/leisure activities and return to paid professional work. In order to reach the goals, patients identified three ways: own resources, family and social support and healthcare system, in total three categories. The most frequently reported own capability was self-motivation. Spouses and children were important sources of family and social support. The most frequently reported healthcare support was cardiac rehabilitation. In traditional care and treatment plans devised by health professionals, patient goals often comprise behavioural changes. When patients identify their own goals and resources with the help of professionals, they include maintaining social relations and being able to return to important activities such as work.

    Acute Coronary Syndrome (ACS) is used to describe the spectrum of coronary artery disease (CAD). Troponin T is the determinant of the most sensitive marker of ACS, but there aren’t all hospitals have this because of expensiveness. Mean Platelet Volume (MPV) is one of the components of a complete blood routine examination and relatively cheap as a marker in ACS. Determining the sensitivity and specificity of MPV in detecting cases of the acute coronary syndrome, 325 subjects’ medical records were from the period of July 2013 to June 2014; 228 ACS patients met the inclusion criteria. 228 subjects showed a risk factor for age ≥45years of more 195 (85.5%). 122 subjects with hypertension (53.5%) and subjects who smoked 118 (51.8%) that suffered most ACS. Subjects with risk factors for diabetes mellitus, obesity, menopause and dyslipidemia in this study was lower than non-diabetic 161 (70.6%), obese189 (82.9%), nonmenopause 196 (86%) and normal lipid 210 (92.1%). But there was norelation between risk factor with MPV and troponin T statistically. The results of diagnostic tests MPV for the evaluation of patients with ACS, sensitivity 92%, specificity 71%, positive predictive value 95% and negative predictive value 58%.

  1. Optical Coherence Tomography Guidance in Management of Acute Coronary Syndrome Caused by Plaque Erosion.

    2018-01-25

    For several decades, most physicians have believed that acute coronary syndrome (ACS) is caused by coronary thrombosis resulting from rupture of vulnerable plaque characterized by a thin fibrous cap overlying a large necrotic core and massive inflammatory cell infiltration. However, nearly one-third of ACS cases are caused by plaque erosion characterized by intact fibrous cap, less or absent necrotic core, less inflammation, and large lumen. Because of the limitations of current imaging modalities, including angiography and intravascular ultrasound, the importance of plaque erosion as a cause of acute coronary events is less well known. Optical coherence tomography (OCT) as an emerging modality with extremely high resolution is the only intravascular imaging modality available for identification of plaque erosion in vivo, which provides new insight into the mechanism of ACS. More importantly, the introduction of OCT to clinical practice enables us to differentiate the patients with ACS caused by plaque erosion from those caused by plaque rupture, thereby providing precise and personalized therapy based on the different underlying mechanisms. We systematically review the morphological characteristics of plaque erosion identified by OCT and its implications for the management of ACS.

    Atherosclerotic plaques underlying most myocardial infarctions have thin fibrous caps and large necrotic cores; however, these features alone do not reliably identify plaques that rupture. Rupture occurs when plaque structural stress (PSS) exceeds mechanical strength. We examined whether PSS could be calculated in vivo based on virtual histology (VH) intravascular ultrasound and whether PSS varied according to plaque composition, subtype, or clinical presentation. A total of 4429 VH intravascular ultrasound frames from 53 patients were analyzed, identifying 99 584 individual plaque components. PSS was calculated by finite element analysis in whole vessels, in individual plaques, and in higher-risk regions (plaque burden ≥70%, mean luminal area ≤4 mm(2), noncalcified VH-defined thin-cap fibroatheroma). Plaque components including total area/arc of calcification (R(2)=0.33; PPSS. PSS was higher in noncalcified VH-defined thin-cap fibroatheroma compared with thick-cap fibroatheromas (median [Q1-Q3], 8.44 [6.97-10.64] versus 7.63 [6.37-9.68]; P=0.002). PSS was also higher in patients with an acute coronary syndrome, where mean luminal area ≤4 mm(2) (8.24 [7.06-9.93] versus 7.72 [6.33-9.34]; P=0.03), plaque burden ≥70% (9.18 [7.44-10.88] versus 7.93 [6.16-9.46]; P=0.02), and in noncalcified VH-defined thin-cap fibroatheroma (9.23 [7.33-11.44] versus 7.65 [6.45-8.62]; P=0.02). Finally, PSS increased the positive predictive value for VH intravascular ultrasound to identify clinical presentation. Finite element analysis modeling demonstrates that structural stress is highly variable within plaques, with increased PSS associated with plaque composition, subtype, and higher-risk regions in patients with acute coronary syndrome. PSS may represent a novel tool to analyze the dynamic behavior of coronary plaques with the potential to improve prediction of plaque rupture. © 2014 American Heart Association, Inc.

    Full Text Available Aim. The study was aimed at comparing the immediate and long-term results of aortic valve replacement in combination with various techniques of intervention for myocardial revascularization, namely: coronary artery bypass grafting (CABG and percutaneous transluminal coronary angioplasty (PTCA.Methods. This randomized prospective controlled study involved 120 cardiac patients over 18 years old with combined aortic valve stenosis and arterial sclerotic disease of coronary arteries. The inclusion criteria were a combination of aortic valve stenosis and a hemodynamically significant lesion of the coronary bed. A comparative analysis of the results obtained in the nearest postoperative period and during 1-year follow-up is presented. Results. Hybrid intervention (aortic valve replacement + percutaneous transluminal coronary angioplasty produces the results which are comparable with those of the control (aortic valve replacement + CABG, with a significantly greater decrease in the peak gradient on the aortic valve. During long-term follow-up, the group of patients who underwent hybrid intervention demonstrated a much higher myocardial infarction rate (12.5 versus 2.5 %, however, the severity of infarctions was significantly lower.Conclusion. PTCA, as compared to CABG, with concomitant coronary artery disease significantly improves the indicators of aortic valve insufficiency and the survival after repeated myocardial infarction, with the matching frequency of acute cerebral circulation abnormalities and the lethality rate in the long-term period.Received 29 August 2016.

    To describe the clinical-epidemiologic profile and the process of care of the non-ST elevation acute coronary syndromes in a tertiary hospital. We analyzed the clinical information, the risk stratification and diagnostic methods, the revascularization therapy and the prescription trends at discharge, of patients with non-ST elevation acute coronary syndromes cared for in one year. Two hundred and eighty-three patients with mean age of 58 years were included (63% men). The largest number of non-ST elevation acute coronary syndromes (88.6%) was found between 50 to 59 years of age. The most common risk factor was hypertension; 82.5% of the patients had a low-intermediate TIMI score; residual ischemia was demonstrated in 37% and coronary obstructions were seen in 80 patients (70%). In 90%, a percutaneous coronary intervention was performed, mainly with drug-eluting Stents (87.5%). At discharge, even though antiplatelet agents and statins were prescribed in more than 90%, other drugs were indicated in a few more than 50% of patients. In this population, non-ST elevation acute coronary syndromes predominates in relatively young men, often with hypertension. To stratify risk, to look for residual ischemia and to revascularize with drug-eluting stents are common practices, but the evidence-based guidelines compliance is still suboptimal.

    We investigated roles of plasma homocysteine and MTHFR gene in relation to risks and treatment responses of depression in ACS. A sample of 969 patients with recent ACS were recruited and 711 followed 1 year later. In addition, of 378 baseline participants with depressive disorder, 255 were randomized to a 24-week double blind trial of escitalopram (N = 127) or placebo (N = 128). A higher homocysteine concentration was independently associated with prevalent depressive disorder at baseline irrespective of MTHFR genotype; and with both incident and persistent depressive disorder at follow-up only in the presence of TT genotype. MTHFR genotype was not itself associated with depressive disorder after ACS. No associations were found with 24-week antidepressant treatment responses. Plasma homocysteine could be a biomarker for depressive disorder particularly in the acute phase of ACS. Focused interventions for those with higher homocysteine level and MTHFR TT genotype might reduce the risk of later depressive disorder. PMID:27626182

    We describe the case of a male patient, aged 76 years, referred for cardiac investigation due to retrosternal chest pain and dyspnea. He had a history of acute myocardial infarction and angioplasties in the last 30 years, including a saphenous vein coronary artery bypass grafting (SVCABG). Echocardiogram showed hypoechoic oval formation near the right ventricle, suggesting a pericardial cyst. Computed angiotomography revealed a predominantly fusiform and thrombosed aneurysmal dilation of the SVCABG to the right coronary artery. SVCABG aneurysms are very rare and potentially fatal. They usually appear in the late postoperative period, and patients are often asymptomatic. On radiography, it is frequently presented as enlargement of the mediastinum, with echocardiography, computed tomography and magnetic resonance imaging being very useful for diagnosis. Coronary angiography is the gold standard to detect these cases. Our report illustrates a rare situation arising late from a relatively common surgery. Due to its severity, proper recognition in the routine assessment of patients with a similar history is essential.

    There is debate regarding the prognostic significance of the absence of significant coronary lesions in patients with non-ST-segment elevation acute myocardial infarction. We investigated long-term prognosis in a contemporary cohort of these patients. Retrospective observational study of 5203 patients with acute coronary syndrome. Propensity score matching was used to create 2 groups of 367 patients with non-ST-segment elevation acute myocardial infarction matched by the absence or presence of significant coronary lesions. In the matched cohort, we determined the impact of the absence of significant coronary lesions on mortality or readmission for acute coronary syndrome for 4.8 (2.6) years after discharge. Mortality or readmission for acute coronary syndrome was lower among patients without significant lesions (26.4% vs 32.7%; P = .09). Mortality in both groups was 19.1%. In contrast, patients without significant lesions had a lower incidence of readmission for acute coronary syndrome (2.0/100 vs 3.9/100 person-years; P = .003). The incidence of mortality or readmission for acute coronary syndrome was similar in patients without significant lesions and those with significant 1-vessel disease (26.4% vs 27.5%; P = .19), but lower than that in patients with 2-vessel disease (37.8%; P = .007) and 3-vessel disease or left main coronary artery disease (41.1%; P = .002). Patients with non-ST-segment elevation acute myocardial infarction and coronary arteries without significant lesions have similar long-term mortality but lower readmission rates for acute coronary syndrome than patients with significant lesions. Mortality or readmission for acute coronary syndrome is similar in patients without significant lesions and patients with 1-vessel disease, but lower than in patients with disease in 2 or more vessels.

    The aim of this study was to investigate the presence of various atypical pneumonia agents (Chlamydia pneumoniae, cytomegalovirus, Mycoplasma pneumoniae), which are considered to have a role in the ethiopathogenesis of atherosclerosis, in aortic biopsies without macroscopically visible plaque and in internal thoracic artery biopsies. Thirty-three patients (group 1), who had undergone coronary bypass operation and 10 non-atherosclerotic patients (group 2), were included in the study. Seventy-six tissue biopsies were taken. Biopsies from the patients in group 1 a were obtained from the atheroma plaque-free aortic tissue and 33 biopsies (group Ib) were obtained from their internal thoracic arteries. Following DNA extraction, nested PCR was used to detect Chlamydia pneumoniae DNA, and real time PCR was used to detect cytomegalovirus and Mycoplasma pneumoniae DNA. Blood parameters (lipid profile, CRP, fibrinogen) of the patients and operation characteristics were recorded. Chlamydia pneumoniae DNA was detected in 5 of 33 biopsy samples from coronary bypass patients, whereas none of the control patients (group 1b and group 2) were positive for this agent (P = 0.001). Neither CMV nor Mycoplasma pneumoniae was detected in IMA and aortic biopsies of both bypass and control patients. Elevated total cholesterol levels (P = 0.02) and positive CRP (P = 0.001) was found in C. pneumoniae positive patients. Prevalence of acute coronary syndrome was significantly higher in C. pneumoniae detected patients compared (P = 0.00 1). Detection of C. pneumoniae DNA in the atheroma free aortic biopsies might indicate that this micro-organism intervened in the progression of atheroma plaque. There was a strong relationship between the detection of this micro-organism in the aortic wall and acute coronary syndrome. The absence of DNA of the corresponding micro-organisms in the IMA wall may show its resistance to infective agents and in turn to atherosclerosis, which is a result of the

    To determine the usefulness of myeloperoxidase in discriminating between patients with acute coronary syndrome and patients with chest pain by other causes. The study included all patients over 18 years of age who come consecutively to the emergency department from September 2015 to December 2015 with chest pain of non-traumatic origin. The initial patient evaluation was performed according to the study protocol for patients with suspected acute coronary syndrome (ACS) in our Emergency Department. This included the serial measurement of troponin, and in this case myeloperoxidase, with serialization on admission and at 6h. For the determination of myeloperoxidase (MPO), a single step sandwich enzyme immunoassay by Siemens, automated on a Dimension analyser, was used. Statistically significant differences were observed in the concentration of myeloperoxidase at time 0 among patients diagnosed with ACS: 505 (413)pmol/L, and non-ACS patients: 388 (195)pmol/L (p<.001), as well as at 6h (p<.001). An area under the curve ROC of 0.824 was obtained at 6h for ACS patients, with a confidence interval of 95% from 0.715 to 0.933 and a level of significance of p<.001. Statistically significant differences were also found in the concentration of myeloperoxidase at time 0 and at 6h among patients with ACS and patients with heart disease other than coronary artery disease. The concentration of MPO helps to differentiate between ACS and non-ACS patients, as well as between ACS patients and patients with heart diseases other than coronary artery disease.

    In this study, we estimated the risk of acute coronary syndrome and stroke associated with several emerging cardiovascular risk factors. This was a case-control study, where an age - and sex-matched acute coronary syndrome group and stroke group were compared with controls. Demographic and clinical data were collected through patient interviews, and blood samples were taken for analysis. In the bivariate analysis, all cardiovascular risk factors analyzed showed as predictors of acute coronary syndrome and stroke, except total cholesterol and smoking. In the multivariate logistic regression model for acute coronary syndrome, hypertension and body mass index, N-terminal section brain natriuretic peptide and pregnancy-associated plasma protein-A were independent predictors. For stroke, the predictors were hypertension, diabetes mellitus, body mass index, and N-terminal section brain natriuretic peptide. Controlling for age, sex, and classical cardiovascular risk factors, N-terminal section brain natriuretic peptide and pregnancy-associated plasma protein-A were independent emerging cardiovascular risk factors for acute coronary syndrome, but pregnancy-associated plasma protein-A was not for stroke. High levels of cardiovascular risk factors in individuals with no episodes of cardiovascular disease requires the implementation of prevention programs, given that at least half of them are modifiable. © 2016 John Wiley & Sons Australia, Ltd.

    Pretest probability helps guide diagnostic testing for patients with suspected acute coronary syndrome and pulmonary embolism. Pretest probability derived from the clinician's unstructured gestalt estimate is easier and more readily available than methods that require computation. We compare the diagnostic accuracy of physician gestalt estimate for the pretest probability of acute coronary syndrome and pulmonary embolism with a validated, computerized method. This was a secondary analysis of a prospectively collected, multicenter study. Patients (N=840) had chest pain, dyspnea, nondiagnostic ECGs, and no obvious diagnosis. Clinician gestalt pretest probability for both acute coronary syndrome and pulmonary embolism was assessed by visual analog scale and from the method of attribute matching using a Web-based computer program. Patients were followed for outcomes at 90 days. Clinicians had significantly higher estimates than attribute matching for both acute coronary syndrome (17% versus 4%; Pgestalt versus 0.78 (95% CI 0.71 to 0.85) for attribute matching. For pulmonary embolism, these values were 0.81 (95% CI 0.79 to 0.92) for clinician gestalt and 0.84 (95% CI 0.76 to 0.93) for attribute matching. Compared with a validated machine-based method, clinicians consistently overestimated pretest probability but on receiver operating curve analysis were as accurate for pulmonary embolism but not acute coronary syndrome.

    The aim of this study was to evaluate the impact of intravascular ultrasound (IVUS) guidance on the final volume of contrast agent used in patients undergoing percutaneous coronary intervention (PCI). To date, few approaches have been described to reduce the final dose of contrast agent in PCIs. We hypothesized that IVUS might serve as an alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of iodine contrast. A total of 83 patients were randomized to angiography-guided PCI or IVUS-guided PCI; both groups were treated according to a pre-defined meticulous procedural strategy. The primary endpoint was the total volume contrast agent used during PCI. Patients were followed clinically for an average of 4 months. The median total volume of contrast was 64.5 ml (interquartile range [IQR]: 42.8 to 97.0 ml; minimum, 19 ml; maximum, 170 ml) in the angiography-guided group versus 20.0 ml (IQR: 12.5 to 30.0 ml; minimum, 3 ml; maximum, 54 ml) in the IVUS-guided group (p MOZART]; NCT01947335).

    Vitamin D deficiency has been consistently linked with cardiovascular diseases. However, results of intervention studies are contradictory. The aim of this study was to evaluate the effect of treatment with calcifediol (25(OH)D 3 ) on the cardiovascular system of patients with non-ST-elevation acute coronary syndrome after percutaneous coronary intervention. A prospective study assessing≥60-year-old patients with non-ST-elevation acute coronary syndrome, coronary artery disease and percutaneous revascularisation. We randomly assigned 41 patients (70.6±6.3 years) into 2 groups: Standard treatment+25(OH)D 3 supplementation or standard treatment alone. Major adverse cardiovascular events (MACE) were evaluated at the conclusion of the 3-month follow-up period. 25(OH)D levels were analysed with regard to other relevant analytical variables and coronary disease extent. Basal levels of 25(OH)D≤50nmol/L were associated with multivessel coronary artery disease (RR: 2.6 [CI 95%:1.1-7.1], P=.027) and 25(OH)D≤50nmol/L+parathormone ≥65pg/mL levels correlated with increased risk for MACE (RR: 4 [CI 95%: 1.1-21.8], P=.04]. One MACE was detected in the supplemented group versus five in the control group (P=.66). Among patients with 25(OH)D levels≤50nmol/L at the end of the study, 28.6% had MACE versus 0% among patients with 25(OH)D>50nmol/L (RR: 1,4; P=.037). Vitamin D deficiency plus secondary hyperparathyroidism may be an effective predictor of MACE. A trend throughout the follow up period towards a reduction in MACE among patients supplemented with 25(OH)D 3 was detected. 25(OH)D levels≤50nmol/L at the end of the intervention period were significantly associated with an increased number of MACE, hence, 25(OH)D level normalisation could improve cardiovascular health in addition to bone health.

    Full Text Available BACKGROUND: Gender-related differences in mortality of acute coronary syndrome (ACS have been reported. The extent and causes of these differences in the Middle-East are poorly understood. We studied to what extent difference in outcome, specifically 1-year mortality are attributable to demographic, baseline clinical differences at presentation, and management differences between female and male patients. METHODOLOGY/PRINCIPAL FINDINGS: Baseline characteristics, treatment patterns, and 1-year mortality of 7390 ACS patients in 65 hospitals in 6 Arabian Gulf countries were evaluated during 2008-2009, as part of the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2. Women were older (61.3±11.8 vs. 55.6±12.4; P<0.001, more overweight (BMI: 28.1±6.6 vs. 26.7±5.1; P<0.001, and more likely to have a history of hypertension, hyperlipidemia or diabetes. Fewer women than men received angiotensin-converting enzyme inhibitors (ACE, aspirin, clopidogrel, beta blockers or statins at discharge. They also underwent fewer invasive procedures including angiography (27.0% vs. 34.0%; P<0.001, percutaneous coronary intervention (PCI (10.5% vs. 15.6%; P<0.001 and reperfusion therapy (6.9% vs. 20.2%; P<0.001 than men. Women were at higher unadjusted risk for in-hospital death (6.8% vs. 4.0%, P<0.001 and heart failure (HF (18% vs. 11.8%, P<0.001. Both 1-month and 1-year mortality rates were higher in women than men (11% vs. 7.4% and 17.3% vs. 11.4%, respectively, P<0.001. Both baseline and management differences contributed to a worse outcome in women. Together these variables explained almost all mortality disparities. CONCLUSIONS/SIGNIFICANCE: Differences between genders in mortality appeared to be largely explained by differences in prognostic variables and management patterns. However, the origin of the latter differences need further study.

    To define the predictors of long-term mortality in patients with type 2 diabetes mellitus and recent acute coronary syndrome. A total of 7226 patients from a randomized trial, testing the effect on cardiovascular outcomes of the dual peroxisome proliferator-activated receptor agonist aleglitazar in patients with type 2 diabetes mellitus and recent acute coronary syndrome (AleCardio trial), were analysed. Median follow-up was 2 years. The independent mortality predictors were defined using Cox regression analysis. The predictive information provided by each variable was calculated as percent of total chi-square of the model. All-cause mortality was 4.0%, with cardiovascular death contributing for 73% of mortality. The mortality prediction model included N-terminal proB-type natriuretic peptide (adjusted hazard ratio = 1.68; 95% confidence interval = 1.51-1.88; 27% of prediction), lack of coronary revascularization (hazard ratio = 2.28; 95% confidence interval = 1.77-2.93; 18% of prediction), age (hazard ratio = 1.04; 95% confidence interval = 1.02-1.05; 15% of prediction), heart rate (hazard ratio = 1.02; 95% confidence interval = 1.01-1.03; 10% of prediction), glycated haemoglobin (hazard ratio = 1.11; 95% confidence interval = 1.03-1.19; 8% of prediction), haemoglobin (hazard ratio = 1.01; 95% confidence interval = 1.00-1.02; 8% of prediction), prior coronary artery bypass (hazard ratio = 1.61; 95% confidence interval = 1.11-2.32; 7% of prediction) and prior myocardial infarction (hazard ratio = 1.40; 95% confidence interval = 1.05-1.87; 6% of prediction). In patients with type 2 diabetes mellitus and recent acute coronary syndrome, mortality prediction is largely dominated by markers of cardiac, rather than metabolic, dysfunction.

    Evidence of the clinical characteristics, treatment and outcomes among Latin American (LA) patients with acute coronary syndromes (ACS) is scarce. ACCESS, international prospective multicenter registry to evaluate risk stratification, management and outcomes in ACS (unstable angina or non-ST elevation myocardial infarction [UA/NSTEMI] or ST elevation myocardial infarction [STEMI]) in developing countries. Primary endpoint: all-cause death at 1 year; all-cause mortality within 30 days was also recorded, Patients with acute ischemic symptoms within 24 hours of symptoms onset and electrocardiographic evidence of ischemia were enrolled. Coronary artery disease was proved by positive invasive or non-invasive tests. Between 2007 and 2008, 4436 patients with ACS (2562 UA/NSTEMI and 2374 STEMI) from eight LA countries. On admission, acute symptoms were identified in 79 % and 90%, respectively. Both groups had a long delay from symptom onset to hospital arrival. Low access to pharmacological (29%) and mechanical reperfusion (32%) were observed. At admission, rates of evidence-based treatment were low in all groups. The most common in-hospital complications were heart failure (10% UA/NSTEMI and 20% STEMI) and recurrent ischemia (8% and 11%). Mortality at 30 days was 2% and 8% at 1 year. ACCESS registry provides contemporary information of patients with ACS in LA and their hospital management and subsequent clinical outcomes.

    Full Text Available Objective: To analyze the effect of preoperative small dose of tirofiban on PCI treatment prognosis in patients with acute coronary syndrome. Methods: A total of 108 cases with acute coronary syndrome who received PCI treatment in our hospital from August 2011 to May 2014 were included for study and randomly divided into observation group and control group by half according to different treatment methods. Control group received PCI treatment alone, observation group received small dose of tirofiban combined with PCI treatment, and then differences in hemorheology indicators, platelet function, left ventricular systolic function and left ventricular diastolic function parameters, serum indicators and so on were compared between two groups after treatment. Results: Whole blood high shear viscosity, whole blood low shear viscosity, reduced high shear viscosity, reduced low shear viscosity, plasma ratio viscosity, erythrocyte aggregation index and erythrocyte deformability index of observation group after treatment were all less than those of control group (P<0.05; PAdT, PAgT, CD62p, CD40L and P-selectin values of observation group after treatment were all lower than those of control group (P<0.05; LPER and LPFR values of observation group 1 week after treatment were higher than those of control group while LTPER and LTPFR values were lower than those of control group (P<0.05; serum GA, MCP-1, PAI-1, NT-proBNP, PAC-1, VCAM-1 and ICAM-1 values of observation group after treatment were all lower than those of control group (P<0.05. Conclusions: Small dose of tirofiban combined with PCI treatment for patients with acute coronary syndrome can effectively enhance therapeutic effect, inhibit platelet activity while protect heart function and optimize long-term treatment outcome.

    Full Text Available Background: Cardiovascular disease is the leading cause of mortality in the western world and its treatment should be optimized to decrease severe adverse events. Objective: To determine the effect of previous use of angiotensin-converting enzyme inhibitors on cardiac troponin I measurement in patients with acute coronary syndrome without ST-segment elevation and evaluate clinical outcomes at 180 days. Methods: Prospective, observational study, carried out in a tertiary center, in patients with acute coronary syndrome without ST-segment elevation. Clinical, electrocardiographic and laboratory variables were analyzed, with emphasis on previous use of angiotensin-converting enzyme inhibitors and cardiac troponin I. The Pearson chi-square tests (Pereira or Fisher's exact test (Armitage were used, as well as the non-parametric Mann-Whitney's test. Variables with significance levels of 0.5 ng / mL were high blood glucose at admission (p = 0.0034 and ST-segment depression ≥ 0.5 mm in one or more leads (p = 0.0016. The use of angiotensin-converting inhibitors prior to hospitalization was associated with troponin ≤ 0.5 ng / mL (p = 0.0482. The C-statistics for this model was 0.77. Conclusion: This study showed a correlation between prior use of angiotensin-converting enzyme inhibitors and reduction in the myocardial necrosis marker troponin I in patients admitted for acute coronary syndrome without ST-segment elevation. However, there are no data available yet to state that this reduction could lead to fewer severe clinical events such as death and re-infarction at 180 days.

    Patients with renal dysfunction are more prone to bleeding when receiving antithrombotic drugs. The aim of the study was to assess the impact of clopidogrel on safety and efficacy in patients with renal dysfunction in non-ST elevation acute coronary syndromes. Patients in the Clopidogrel in Unstable Angina to Prevent Recurrent Events (CURE) trial were analysed to assess the relationship of chronic kidney disease to cardiovascular outcomes. Renal function was estimated by the glomerular filtration rate computed from the baseline serum creatinine measurements in 12 253 (97.5%) patients enrolled in the trial. Patients were grouped into tertiles of glomerular filtration rate. The primary outcome (cardiovascular death, myocardial infarction, stroke combined) occurred more frequently in the lowest glomerular filtration rate tertile. The bleeding risk was also significantly increased in patients in this tertile, compared with the other two. The beneficial effect of adding clopidogrel to standard treatment in non-ST elevation acute coronary syndrome was observed in all three tertiles of renal function {(lower third relative risk (RR)=0.89 [95% confidence interval (CI) 0.76-1.05]; medium third RR=0.68 (95% CI 0.56-0.84); upper third RR=0.74 (95% CI 0.60-0.93) (P for heterogeneity=0.11)}. Clopidogrel treatment significantly increased the risk of minor bleeding in all tertiles of renal function. The risk of major or life-threatening bleeding increased moderately with the addition of clopidogrel to standard treatment [lower third RR=1.12 (95% CI 0.83-1.51); medium third RR=1.4 (95% CI 0.97-2.02); upper third RR=1.83 (95% CI 1.23-2.73)], but this did not appear to be greatest in those with the lowest renal function. Even mild chronic kidney disease worsens the prognosis in patients with non-ST elevation acute coronary syndromes. Clopidogrel was beneficial and safe in patients with and without chronic kidney disease.

    Ischaemic heart disease is the leading cause of in-hospital mortality in Sri Lanka. Acute Coronary Syndrome Sri Lanka Audit Project (ACSSLAP) is the first national clinical-audit project that evaluated patient characteristics, clinical outcomes and care provided by state-sector hospitals. ACSSLAP prospectively evaluated acute care, in-hospital care and discharge plans provided by all state-sector hospitals managing patients with ACS. Data were collected from 30 consecutive patients from each hospital during 2-4 weeks window. Local and international recommendations were used as audit standards. Data from 87/98 (88.7%) hospitals recruited 2177 patients, with 2116 confirmed as having ACS. Mean age was 61.4±11.8 years (range 20-95) and 58.7% (n=1242) were males. There were 813 (38.4%) patients with unstable angina, 695 (32.8%) with non-ST-elevation myocardial infarction (NSTEMI) and 608 (28.7%) with ST-elevation myocardial infarction (STEMI). Both STEMI (69.9%) and NSTEMI (61.4%) were more in males (P<0.001). Aspirin, clopidogrel and statins were given to over 90% in acute setting and on discharge. In STEMI, 407 (66.9%) were reperfused; 384 (63.2%) were given fibrinolytics and only 23 (3.8%) underwent primary percutaneous coronary intervention (PCI). Only 42.3 % had thrombolysis in <30 min and 62.5% had PCI in <90 min. On discharge, beta-blockers and ACE inhibitors/angiotensin II receptor blockers were given to only 50.7% and 69.2%, respectively and only 17.6% had coronary interventions planned. In patients with ACS, aspirin, clopidogrel and statin use met audit standards in acute setting and on discharge. Vast majority of patients with STEMI underwent fibrinolyisis than PCI, due to limited resources. Primary PCI, planned coronary interventions and timely thrombolysis need improvement in Sri Lanka. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Over the past two decades, the use of multiple biomarkers has changed cardiovascular disease management. Recently, several trials have assessed the diagnostic and prognostic performances of copeptin, especially in patients with heart failure or acute coronary syndromes. Primary results are interesting, with copeptin looking promising for: the management of patients who present at emergency departments early after chest pain onset and the risk stratification of patients with heart failure. The purpose of this article is to review the data on the place of copeptin in the management of patients with chest pain or heart failure. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Biomarkers, other than cardiac troponin, with potential sensitivity and selectivity that provide diagnostic and prognostic insights into the tissue-specific injury processes underlying acute coronary syndrome and their possible use in risk stratification algorithms are discussed. Such biomarkers may be useful as complementary or alternative to cardiac troponin (I or T) assays in early diagnosis of acute coronary syndrome, as well as for monitoring acute coronary syndrome progression and prognosis assessment. The information included in this article is based on a critical analysis of selected published biomedical literature accessible through the United States National Library of Medicine's MEDLINE-PubMed and Scopus search engines.

    Serum uric acid (SUA) is the final product of purine metabolism in humans. The present study aimed to identify a potential association between serum UA and cardiac troponin I (cTnI) levels and to find out whether uric acid could differentiate patients presenting with the acute myocardial infarction (AMI) and unstable angina pectoris (UAP) in hyperuricemic and normouricemic acute coronary syndrome (ACS) patients. Eighty ACS patients, aged 50-83 years, were enrolled in the study, 40 of them presenting with AMI and 40 with UAP. Frequency of patients with serum uric level over threshold for hyperuricemia was investigated and two groups of patients were formed such as hyperuricemic and normouricemic groups (A and B groups, respectively) independently of type of ACS. Those groups of patients were also subjected to cTnI measurement. Levels of SUA are associated with the type of ACS in the hyperuricemic ACS patients (AMI versus UAP, 499(458-590), 425(400-447) mmol/L, p=0.007, respectively). Uric acid correlated significantly with cTnI, moderate positively in the group A (rho=0.358, p=0.038) and moderate negatively in the group B (r=-0.309, p=0.037) of ACS patients. Multiple logistic regression analysis revealed that cTnI and age were independently associated with the SUA levels in the group A of ACS patients. Serum uric acid differentiates AIM and UAP patients in hyperuricemic group of acute coronary syndrome. Therefore it can be used as nonspecific parameter for evaluation of the myocardial lesion extent only in hyperuricemic ACS patients. This is supported by finding that cTnI along with age predicts SUA level in hyperuricemic ACS patients.

    In view of recent therapeutic breakthroughs in acute coronary syndromes (ACS) and essential demographic and socioeconomic changes in Greece, we conducted the prospective, multi-center, nationwide PHAETHON study (An Epidemiological Cohort Study of Acute Coronary Syndromes in the Greek Population) that aimed to recruit a representative cohort of ACS patients and examine current management practices and patient prognosis. The PHAETHON study was conducted from May 2012 to February 2014. We enrolled 800 consecutive ACS patients from 37 hospitals with a proportional representation of all types of hospitals and geographical areas. Patients were followed for a median period of 189 days. Outcome was assessed with a composite endpoint of death, myocardial infarction, stroke, urgent revascularization and urgent hospitalization for cardiovascular causes. The mean age of patients was 62.7 years (78% males). The majority of patients (n=411, 51%) presented with ST-elevation myocardial infarction (STEMI), whereas 389 patients presented with NSTEMI (n=303, 38%) or UA (n=86, 11%). Overall, 58.8% of the patients had hypertension, 26.5% were diabetic, 52.5% had dyslipidemia, 71.1% had a smoking history (current or past), 25.8% had a family history of coronary artery disease (CAD) and 24.1% had a prior history of CAD. In STEMI patients, 44.5% of patients were treated with thrombolysis, 38.9% underwent a coronary angiogram (34.1% were treated with primary percutaneous coronary intervention) and 16.5% did not receive urgent treatment. The pain-to-door time was 169 minutes. During hospitalization, 301 (38%) patients presented one or more complications, and 13 died (1.6%). During follow-up, 99 (12.6%) patients experienced the composite endpoint, and 21 died (2.7%). The PHAETHON study provided valuable insights into the epidemiology, management and outcome of ACS patients in Greece. Management of ACS resembles the management observed in other European countries. However, several issues

    Positive psychological constructs, such as optimism, are associated with greater participation in cardiac health behaviors and improved cardiac outcomes. Positive psychology interventions, which target psychological well-being, may represent a promising approach to improving health behaviors in high-risk cardiac patients. However, no study has assessed whether a positive psychology intervention can promote physical activity following an acute coronary syndrome. In this article we will describe the methods of a novel factorial design study to aid the development of a positive psychology-based intervention for acute coronary syndrome patients and aim to provide preliminary feasibility data on study implementation. The Positive Emotions after Acute Coronary Events III study is an optimization study (planned N = 128), subsumed within a larger multiphase optimization strategy iterative treatment development project. The goal of Positive Emotions after Acute Coronary Events III is to identify the ideal components of a positive psychology-based intervention to improve post-acute coronary syndrome physical activity. Using a 2 × 2 × 2 factorial design, Positive Emotions after Acute Coronary Events III aims to: (1) evaluate the relative merits of using positive psychology exercises alone or combined with motivational interviewing, (2) assess whether weekly or daily positive psychology exercise completion is optimal, and (3) determine the utility of booster sessions. The study's primary outcome measure is moderate-to-vigorous physical activity at 16 weeks, measured via accelerometer. Secondary outcome measures include psychological, functional, and adherence-related behavioral outcomes, along with metrics of feasibility and acceptability. For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises

    Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20% are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a final diagnosis of multiple endocrine neoplasia with pheochromocytoma and medullary thyroid carcinoma (MTC).

    Full Text Available Background The local injection of novel cardioprotective study drugs prior to percutaneous coronary intervention could cause embolisation of thrombus, resulting in increased reperfusion injury and subsequent infarct size. The aim of this study was to assess the safety of the delivery of an intracoronary therapy delivered during primary percutaneous coronary intervention for acute myocardial infarction prior to the re-establishment of thrombolysis in myocardial infarction III flow. Methods One hundred sixty-seven patients with acute myocardial infarction successfully reperfused through primary percutaneous coronary intervention and undergoing Cardiac MRI within the first week after reperfusion were studied. Patients either underwent the delivery of an intracoronary agent (IMP or placebo prior to balloon dilatation ( n  = 80 or standard primary percutaneous coronary intervention procedure ( n  = 117. Results Baseline characteristics were similar between the two groups. There were a similar number of successful procedures (IC IMP 75 (93.8% vs. No IMP 114, (97.4%, p  = 0.374, rates of no-reflow (IC IMP 1 (1.3% vs. No IMP 2 (1.7%, p  = 0.99 and levels of ST segment resolution (88.5% IC IMP vs. No IC IMP 87.0%, p  = 0.669 between the two groups. Similar levels of microvascular obstruction were seen between the two groups with a trend to reduced infarct size, and improved ejection fractions in the IMP group. Lower MACE rates were seen in the IMP group. Conclusion The local intracoronary infusion of potential cardioprotective agents prior to the restoration of TIMI flow in patients undergoing primary percutaneous coronary intervention for acute myocardial infarction appears to be safe and does not increase microvascular damage. This route should be considered when testing novel cardioprotective agents.

    Gender associations with acute coronary syndrome (ACS), remain inconsistent. Gender-specific data in the Saudi Project for Assessment of Coronary Events registry, launched in December 2005 and currently with 17 participating hospitals, were explored. A prospective multicenter study of patient with ACS in secondary and tertiary care centers in Saudi Arabia were included in this analysis. Patients enrolled from December 2005 until December 2007 included those presented to participating hospitals or transferred from non-registry hospitals. Summarized data were analyzed. Of 5061 patients, 1142 (23%) were women. Women were more frequently diagnosed with non ST-segment elevation myocardial infarction (NSTEMI [43%]) than unstable angina (UA [29%]) or ST-segment elevation myocardial infarction (STEMI [29%]). More men had STEMI (42%) than NSTEMI (37%) or UA (22%). Men were younger than women (57 vs 63 years) who had more diabetes, hypertension, and hyperlipidemia. More men had a history of coronary artery disease. More women received angiotensin receptor blockers (ARB) and fewer had percutaneous coronary intervention (PCI). Gender differences in the subset of STEMI patients were similar to those in the entire cohort. However, gender differences in the subset of STEMI showed fewer women given b-blockers, and an insignificant PCI difference between genders. Thrombolysis rates between genders were similar. Overall, in-hospital mortality was significantly worse for women and, by ACS type, was significantly greater in women for STEMI and NSTEMI. However, after age adjustment there was no difference in mortality between men and women in patients with NSTEMI. The multivariate-adjusted (age, risk factors, treatments, door-to-needle time) STEMI gender mortality difference was not significant (OR=2.0, CI: 0.7-5.5; P=.14). These data are similar to other reported data. However, differences exist, and their explanation should be pursued to provide a valuable insight into understanding

    Acute coronary syndromes (ACS) in young patients are uncommon and their influence on morbidity and mortality in this population is still debated. We investigated clinical and angiographic characteristics, risk factors and outcome in young patients diagnosed with ACS, compared with those of older patients, evaluating survival free from death and/or nonfatal myocardial infarction (MI) and/or coronary revascularization (primary endpoint), and then with respect to each component of the primary endpoint. We retrospectively analyzed 1696 patients diagnosed with ACS between 2007 and 2013. 116 were aged ≤45 years (young adults), 1116 were >45 and <75 years (older adults) and 464 were ≥75 years. Young adults were mostly male, with a prevalent diagnosis of STEMI, had less frequently typical cardiovascular risk factors and lower prevalence of extensive coronary artery disease. Over a median 3 years follow up, survival free from composite endpoint was better in young than in older adult patients (11.2 vs. 24.2%; p = 0.001), mainly due to a lower rate of death while the occurrence of non fatal MI and of coronary revascularization was similar (7.8 vs. 8.7%, p = 0.86; 8.7 vs. 12.9%, p = 0.23 respectively). Diabetes was the strongest independent risk factor of worse prognosis in the young cohort (OR 3.47; 95% CI 1.01-11.9; p = 0.04). Young adults showed peculiar clinical features and lower mortality compared with older adults. Morbidity was not different between the two populations, with diabetes independently associated with a worse prognosis.

    This study assessed current practices in relation to coronary risk factors, therapy and its results in patients with acute ischemic coronary syndromes (AICS) with or without ST-segment-elevation myocardial infarction [MI], from data collected in the National Registry of AICS [RENASICA] in México; Eigh teen hospitals [2nd. and 3rd level of medical attention] recruited patients for the registry, 4,253 patients were enrolled, 2,773 [65.2%] without AICSST segment elevation and 1480 [34.8%] patients with ST segment elevation MI. Chest pain was the main cause for seeking medical attention to an emergency service (90.5%) and 50% of the patients referred it in advance. AICS was mainly observed in men in their sixth decade of age. Age, ST segment depression [> 2 mm], CKMB [> 2 values above normal] and the extension of the coronary artery disease allow to predict mortality and the combination of mortality and myocardial infarction. Only 50.4% of the eligible patients with AICS and ST-segment-elevation myocardial infarction received thrombolytic therapy. Of the eligible cohort of AICS only 58% patients could an hemodynamic study be performed. In 55% of them, a percutaneous coronary intervention procedure was done (PTCA-Stent implantation). Aspirin [ASA] and heparin were prescribed in 70% of the patients at entry to the ward and the same percentage of AICS patients received ASA after discharge. Low molecular weight heparin and IIb/IIIa receptor platelet antagonists were used in a low proportion of patients. RENASICA provides information related to AICS patients that could help the mexican health authorities to apply better the health resources in the forthcoming future for the treatment of AICS.

    Objective: To evaluate the impact of coronary CT angiography (coronary CTA) or “triple-rule-out” CT angiography (TRO-CTA) on patient management in the work-up of patients with acute chest pain and an intermediate cardiac risk profile. Materials and methods: 100 patients with acute chest pain and an intermediate cardiac risk for acute coronary syndrome (ACS) underwent coronary CTA or TRO-CTA for the evaluation of chest pain. Patients with a high and low cardiac risk profile were not included in this study. All patients with significant coronary stenosis >50% on coronary CTA underwent invasive coronary catheterization (ICC). Important other pathological findings were recorded. All patients had a 90-day follow-up period for major adverse cardiac events (MACE). Results: Based on a negative coronary CTA 60 of 100 patients were discharged on the same day. None of the discharged patients showed MACE during the 90-day follow-up. Coronary CTA revealed a coronary stenosis >50% in 19 of 100 patients. ICC confirmed significant coronary stenosis in 17/19 patients. Among the 17 true positive patients, 9 underwent percutaneous coronary intervention with stent implantation, 7 were received intensified medical therapy, and 1 patient underwent coronary artery bypass surgery. A TRO-CTA protocol was performed in 36/100 patients due to elevated D-dimer levels. Pulmonary embolism was present in 5 patients, pleural effusion of unknown etiology in 3 patients, severe right ventricular dysfunction with pericardial effusion in 1 patient, and an incidental bronchial carcinoma was diagnosed in 1 patient. Conclusion: Coronary CTA and TRO-CTA allow a rapid and safe discharge in the majority of patients presenting with acute chest pain and an intermediate risk for ACS while at the same time identifies those with significant coronary artery stenosis

    Full Text Available Global Registry of Acute Coronary Events (GRACE risk score and red blood cell distribution width (RDW content can both independently predict major adverse cardiac events (MACEs in patients with acute coronary syndrome (ACS. We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58% patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40. GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p < 0.001; 1.699; 1.294-2.232; p < 0.001; respectively. Furthermore, Kaplan-Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001. For GRACE score alone, the area under the receiver operating characteristic (ROC curve for MACEs was 0.749 (95% CI: 0.707-0.787. The area under the ROC curve for MACEs increased to 0.805 (0.766-0.839, p = 0.034 after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001 and integrated discrimination improvement (IDI = 0.023, p = 0.002. Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    The study aim was to compare two different stress echocardiography interpretation techniques based on the correlation with thrombosis in myocardial infarction (TIMI ) flow grading from acute coronary syndrome (ACS) patients. Forty-one patients with suspected ACS were studied before diagnostic coronary angiography with myocardial contrast echocardiography (MCE) at rest and at stress. The correlation of visual interpretation of MCE and TIMI flow grade was significant. The quantitative analysis (myocardial perfusion parameters: A, β, and A × β) and TIMI flow grade were significant. MCE visual interpretation and TIMI flow grade had a high degree of agreement, on diagnosing myocardial perfusion abnormality. If one considers TIMI flow grade <3 as abnormal, MCE visual interpretation at rest had 73.1% accuracy with 58.2% sensitivity and 84.2% specificity and at stress had 80.4% accuracy with 76.6% sensitivity and 83.3% specificity. The MCE quantitative analysis has better accuracy with 100% of agreement with different level of TIMI flow grading. MCE quantitative analysis at stress has showed a direct correlation with TIMI flow grade, more significant than the visual interpretation technique. Further studies could measure the clinical relevance of this more objective approach to managing acute coronary syndrome patient before percutaneous coronary intervention (PCI). PMID:22778555

    The mechanisms responsible for increased cardiovascular risk associated with HIV-1 infection are incompletely defined. Using flow cytometry, in the present study, we examined activation phenotypes of monocyte subpopulations in patients with HIV-1 infection or acute coronary syndrome to find common cellular profiles. Nonclassic (CD14(+)CD16(++)) and intermediate (CD14(++)CD16(+)) monocytes are proportionally increased and express high levels of tissue factor and CD62P in HIV-1 infection. These proportions are related to viremia, T-cell activation, and plasma levels of IL-6. In vitro exposure of whole blood samples from uninfected control donors to lipopolysaccharide increased surface tissue factor expression on all monocyte subsets, but exposure to HIV-1 resulted in activation only of nonclassic monocytes. Remarkably, the profile of monocyte activation in uncontrolled HIV-1 disease mirrors that of acute coronary syndrome in uninfected persons. Therefore, drivers of immune activation and inflammation in HIV-1 disease may alter monocyte subpopulations and activation phenotype, contributing to a pro-atherothrombotic state that may drive cardiovascular risk in HIV-1 infection.

    The troponin I serum level is widely used in acute coronary syndrome patients for their classification. The qualitative assay is faster and more available than the quantitative assay. The objective was to determine the operating characteristics of a qualitative troponin I assay compared with a quantitative method. This is a prospective observational study and patients suspected to have acute coronary syndrome were enrolled. A rapid troponin I test and a quantitative assay were carried out for each patient on arrival and 6 h after admission. A total of 262 patients were enrolled. The degree of agreement between the second rapid qualitative and quantitative troponin I was excellent (κ=0.946; 95% confidence interval, 0.903-0.989). The sensitivity, specificity, negative predictive value, and positive predictive value of the rapid qualitative troponin I test were 92.6, 100, 96.8, and 100%, respectively. In conclusion, this study reveals an excellent agreement between quantitative and qualitative bedside assays 6 h after admission in a sample of Iranian patients in the emergency department.

    To investigate factors associated with enrollment and participation in cardiac rehabilitation (CR) in Korea. Patients admitted to four university hospitals with acute coronary syndrome between June 2014 and May 2016 were enrolled. The Cardiac Rehabilitation Barriers Scale (CRBS) made of 21-item questionnaire and divided in four subdomains was administered during admission. CRBS items used a 5-point Likert scale and ≥2.5 was considered as a barrier. Differences between CR non-attender and CR attender, or CR non-enroller and CR enroller in subscale and each items of CRBS were examined using the chi-square test. The CR participation rate in four hospitals was 31% (170 of the 552). Logistical factors (odds ratio [OR]=7.61; 95% confidence interval [CI], 4.62-12.55) and comorbidities/functional status (OR=6.60; 95% CI, 3.95-11.01) were identified as a barrier to CR enrollment in the subdomain analysis. Among patients who were enrolled (agreed to participate in CR during admission), only work/time conflict was a significant barrier to CR participation (OR=2.17; 95% CI, 1.29-3.66). Diverse barriers to CR participation were identified in patients with acute coronary syndrome. Providing the tailored model for CR according to the individual patient's barrier could improve the CR utilization. Further multicenter study with large sample size including other CR indication is required.

    Positive psychological constructs, especially optimism, have been linked with superior cardiovascular health. However, there has been minimal study of positive constructs in patients with acute coronary syndrome (ACS), despite the prevalence and importance of this condition. Furthermore, few studies have examined multiple positive psychological constructs and multiple cardiac-related outcomes within the same cohort to determine specifically which positive construct may affect a particular cardiac outcome. The Gratitude Research in Acute Coronary Events (GRACE) study examines the association between optimism/gratitude 2weeks post-ACS and subsequent clinical outcomes. The primary outcome measure is physical activity at 6months, measured via accelerometer, and key secondary outcome measures include levels of prognostic biomarkers and rates of nonelective cardiac rehospitalization at 6months. These relationships will be analyzed using multivariable linear regression, controlling for sociodemographic, medical, and negative psychological factors; associations between baseline positive constructs and subsequent rehospitalizations will be assessed via Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessment; the cohort had a mean age of 61.5+/?10.5years and was 84% men; this was the first ACS for 58% of participants. The GRACE study will determine whether optimism and gratitude are prospectively and independently associated with physical activity and other critical outcomes in the 6months following an ACS. If these constructs are associated with superior outcomes, this may highlight the importance of these constructs as independent prognostic factors post-ACS. Copyright © 2015 Elsevier Inc.

    Hyperglycemia at admission seems to identify a subgroup of patients with acute coronary syndromes with poorer outcome. The aim of this study was to evaluate the impact of the glycemic variation during hospitalization in long-term mortality in nondiabetic patients. Retrospective study of 2043 consecutive patients without known diabetes mellitus admitted for acute coronary syndrome in a single coronary care unit from May 2007 through August 2013. The population was divided in quartiles regarding glycemia at admission (≤ 90 mg/dL, n = 374; 90-140 mg/dL, n = 1307; 141-180 mg/dL, n = 230; ≥ 181mg/dL, n = 111) and the mortality rate quantified for patients with glycemic variation above/below the mean for their respective quartile. The median follow-up was about 1200 days. The all-cause mortality during follow-up was significantly and successively higher in the upper quartiles (9.1%, 9.7%, 13.5% and 18.9%; P = .007). Multivariate regression analysis showed that hyperglycemia at admission (≥ 181mg/dL) was a strong independent predictor of mortality during follow-up (hazard ratio = 1.74; 95% confidence interval, 1.07-2.8; P = .027). In the fourth quartile (≥ 181mg/dL), the mortality is higher in patients with higher variations of glycemia (37.5% vs 8.5%; P < .001). Hyperglycemia at admission is a predictor of all-cause mortality in our population. The mortality is higher in patients with higher glycemic variations. More studies are needed to confirm these data.

    Acute coronary syndromes (ACS) are life-threatening medical emergencies that require urgent treatment, posing particular challenges for systems of health care in regional and remote parts of the world characterised by large distances and widely dispersed populations and healthcare facilities. Northern Australia is such an environment. The prevalence of cardiovascular risk factors, coronary artery disease and ACS (myocardial infarction and unstable angina) in northern Australia is amongst the highest in Australia. Despite the high burden of disease, appropriate healthcare services to address these important health challenges have been inadequate. The Australian Commission on Safety and Quality in Health Care has released a Clinical Care Standard for Acute Coronary Syndromes and the National Heart Foundation of Australia has developed an ACS Capabilities Framework, which together define minimum standards of care regardless of the patient's location. Strategies such as uniform state-wide ACS clinical pathways provide guidance on how evidence-based care can be provided in a range of geographical settings and to all populations, including Indigenous Australians. The continuing evolution of cardiac catheter laboratories in Townsville, Cairns, Mackay and Darwin has facilitated improved treatment for ACS in northern Australia, and has supported the development of region-wide, integrated, multidisciplinary pathways of care. Systems of care in ACS require consideration of the perspectives of the patient (from symptom onset to long-term secondary prevention of further events), the health system ('dissolving' traditional regional silos of care to enable a higher critical mass, greater cooperation, better communication and improved efficiency) and healthcare disciplines and services (including ambulance, retrieval, local health centres and local hospitals, tertiary centres, cardiac rehabilitation and general practice).

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty

  8. Hemoglobin A1c Levels Predicts Acute Kidney Injury after Coronary Artery Bypass Surgery in Non-Diabetic Patients

    Cevdet Ugur Kocogulları

    Full Text Available Abstract INTRODUCTION: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS: 202 non-diabetic patients with normal renal function (serum creatinine <1.4 mg/dl who underwent isolated coronary bypass were analyzed. Hemoglobin A1c level was measured at the baseline examination. Patients were separated into two groups according to preoperative Hemoglobin A1c level. Group 1 consisted of patients with preoperative HbA1c levels of < 5.6% and Group 2 consisted of patients with preoperative HbA1c levels of ≥ 5.6%. Acute kidney injury diagnosis was made by comparing baseline and postoperative serum creatinine to determine the presence of predefined significant change based on the Kidney Disease Improving Global Outcomes (KDIGO definition. RESULTS: Acute kidney injury occurred in 19 (10.5% patients after surgery. The incidence of acute kidney injury was 3.6% in Group 1 and 16.7% in Group 2. Elevated baseline hemoglobin A1c level was found to be associated with acute kidney injury (P=0.0001. None of the patients became hemodialysis dependent. The cut off value for acute kidney injury in our group of patients was 5.75%. CONCLUSION: Our findings suggest that, in non-diabetics, elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. Prospective randomized studies in larger groups are needed to confirm these results.

    To investigate the association of renal insufficiency and clinical outcomes in patients with acute coronary syndrome(ACS). The study was a multi-centre register study including 3,589 ACS patients coming from 39 centers across China who had received percutaneous coronary intervention(PCI) prior to 1st February, 2007. Estimated glomerular filtration rate (eGFR) was calculated for all patients using the 4-variable MDRD equation with the serum creatinine obtained before angiography. The association between renal insufficiency and clinical outcomes and the presence of in-hospital death and bleeding was studied by Fisher's exact test. Multi-variable analysis on the risk factors of in-hospital bleeding was done by logistic regression test. The mean age of the study population was (61.74+/-11.37) years (ranging from 23 years to 92 years)and 76.5% (2,746/3,589) of the population was male. Only 90 patients (2.51%) were known to have chronic kidney disease at the time of admission and 144 patients(4.01%) had serum creatinine levels above 133 micromol/L. However, after the evaluation of renal status by the MDRD equation, 2,250 patients (63.1%)showed a reduction in eGFR of less than 90 mL/min, of whom, 472 (13.1%) even reached the level of moderate renal insufficiency (eGFRchronic total occlusion lesions(CTO) and eight (0.22%) needed shift to coronary artery bypass grafting (CABG) after angiography. Both the presence of CTO lesions and CABG were proved to be associated with decrease of renal function through Fisher's exact test (P= 0.005 8 and 0.041, respectively). The in-hospital mortality rate was 0.47%(17/3 589) which was associated with the degree of renal insufficiency (P=0.001 3). A total of 75 patients(2.09%) of in-hospital bleeding were recorded with 26 patients(0.72%) diagnosed as major bleeding events. 92% (69/75) of the bleeding events occurred after PCI. Bleeding was found to be associated with the degree of renal insufficiency in every type of antithrombotic

    Background Coronary heart disease and acute coronary syndrome remain significant public health problems. The effect of acute coronary syndrome on mortality and morbidity is largely dependent on the time from symptom onset to the time of reperfusion, but patient delay in presenting for treatment is the main reason timely reperfusion is not received. Objectives We tested the effect of an education and counseling intervention on knowledge, attitudes and beliefs about acute coronary syndrome symptoms and the appropriate response to symptoms, and identified patient characteristics associated with changes in knowledge, attitudes and beliefs over time. Methods We conducted a 2-group randomized controlled trial in 3,522 people with coronary heart disease. The intervention group received a 40 minute, one-on-one education and counseling session. The control group received usual care. Knowledge, attitudes and beliefs were measured at baseline, 3 and 12 months using the Acute Coronary Syndrome Response Index and analyzed with repeated measures analysis of variance. Results Knowledge, attitudes and beliefs scores increased significantly from baseline in the intervention group compared to the control group at 3 months, and these differences were sustained at 12 months (p = .0005 for all). Higher perceived control over cardiac illness was associated with more positive attitudes (p<.0005) and higher state anxiety was associated with lower levels of knowledge (p<.05), attitudes (p<.05) and beliefs (p<.0005). Conclusion A relatively short education and counseling intervention increased knowledge, attitudes and beliefs about acute coronary syndrome and response to acute coronary syndrome symptoms in individuals with coronary heart disease. Higher perceived control over cardiac illness was associated with more positive attitudes and higher state anxiety was associated with lower levels of knowledge, attitudes and beliefs about responding to the health threat of possible acute coronary

These patients were evaluated for ischemic events, including AMI, during follow-up using an end point committee adjudication of AMI as reference standard.Results: Of 5,719 included patients, 285 patients suffered AMI within a mean follow-up time of 3 years after stent implantation. An AMI discharge diagnosis (primary or secondary from any acute or elective admission had a sensitivity of 95%, a specificity of 93%, and a positive predictive value of 42%. Restriction to acute admissions decreased the sensitivity to 94% but increased the specificity to 98% and the positive predictive value to 73%. Further restriction to include only AMI as primary diagnosis from acute admissions decreased the sensitivity further to 82%, but increased the specificity to 99% and the positive predictive value to 81%. Restriction to patients admitted to hospitals with a coronary angiography catheterization laboratory increased the positive predictive value to 87%.Conclusion: Algorithms utilizing additional information from the Danish National Patient Registry yield different sensitivities, specificities, and predictive

    OBJECTIVE: To test the hypothesis that mutations in the vascular endothelial growth factor (VEGF) gene are associated with plasma concentration of VEGF and subsequently the ability to influence coronary collateral arteries in patients with coronary heart disease (CHD). METHODS: Blood samples from...... patients with chronic ischemic heart disease (n=53) and acute coronary syndrome (n=61) were analysed. Coronary collaterals were scored from diagnostic biplane coronary angiograms. RESULTS: The plasma concentration of VEGF was increased in patients with acute compared to chronic CHD (p=0.01). The genotype......-1154 and coronary collateral size (p=0.03) and a significant association between the VEGF plasma concentration and the collateral size (p=0.03). CONCLUSION: VEGF plasma concentration seems related to coronary collateral function in patients with CHD. The results did not support the hypothesis...

    Full Text Available Patients with multivessel coronary artery disease are more likely to have extensive atherosclerosis that involves other major arteries. Critical subclavian artery (SCA stenosis can result in coronary subclavian steal syndrome that may present as recurrent ischemia and even myocardial infarction in patients with coronary artery bypass graft (CABG. In patients with concomitant severe native coronary disease, occluded saphenous venous grafts (SVG to other arteries, percutaneous intervention on critical subclavian artery (SCA stenosis that will compromise the blood flow to left internal mammary graft (LIMA and left anterior descending (LAD artery will be a high-risk procedure and may be associated with cardiogenic shock, especially in patients with preexisting ischemic cardiomyopathy. The use of percutaneous left ventricular (LV assist device like Impella will offer better hemodynamic support and coronary perfusion and therefore results in decreased myocardial damage, maximized residual cardiac function, and lower incidence of cardiogenic shock.

    Albuminuria is associated with cardiovascular (CV) outcomes. We evaluated albuminuria, alone and in combination with estimated glomerular filtration rate (eGFR), as a predictor of mortality and CV morbidity in 12,944 patients with non-ST-segment elevation acute coronary syndromes. Baseline serum creatinine and urinary dipsticks were obtained, with albuminuria stratified into no/trace albuminuria, microalbuminuria (≥30 but albuminuria and creatinine values were available in 9473 patients (73.2%). More patients with macroalbuminuria, versus no/trace albuminuria, had diabetes (66% vs 27%) or hypertension (86% vs 68%). Rates for CV death and overall mortality per strata were 3.1% and 4.8% (no/trace albuminuria); 5.8% and 9.0% (microalbuminuria); and 7.7% and 12.6% (macroalbuminuria) at 2 years of follow-up. Corresponding rates for CV death or MI were 12.2%, 16.9%, and 23.5%, respectively. Observed acute kidney injury rates were 0.6%, 1.2%, and 2.9% (n = 79), respectively. Adjusted HRs for macroalbuminuria on CV mortality were 1.65 (95% CI 1.15-2.37), and after adjustment with eGFR, 1.37 (95% CI 0.93-2.01). Corresponding HRs for overall mortality were 1.82 (95% CI 1.37-2.42) and 1.47 (95% CI 1.08-1.98). High-risk patients with non-ST-segment elevation acute coronary syndromes and albuminuria have increased morbidity and increased overall mortality independent of eGFR. Copyright © 2016 Elsevier Inc.
