    1996-01-01

    It is well established that recanalisation of the infarct-related artery is of great benefit in the early hours after acute myocardial infarction. This can be achieved by the use of thrombolytic agents and/or by percutaneous transluminal coronary angioplasty (PTCA). This article reviews data on the role of primary PTCA and summarises current opinion on its use.

  5. Contribution of inhibitory receptor glycoprotein iib / iiia in coronary angioplasty and acute coronary syndrome, about 152 patients

    International Nuclear Information System (INIS)

    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.

    We studied the factors which may induce acute high grade restenosis in emergency percutaneous transluminal coronary angioplasty (PTCA). PTCA was attempted in 50 patients with acute myocardial infarction, and the balloon catheter passed successfully across the occlusion site in 47 (94%) of the patients. These 47 patients were analyzed. "Acute restenosis" was defined as a lesion which was revascularized to less than 50% luminal reduction narrowed again to more than 75% luminal reduction...

    Topaz, On; Luxenberg, Michael; Schumacher, Audrey

    1994-07-01

    Patients who sustain complicated acute myocardial infarction in whom thrombolytic agents either fail or are contraindicated often need mechanical revascularization other than PTCA. In 24 patients with acute infarction complicated by continuous chest pain and ischemia who either received lytics or with contraindication to lytics, a holmium:YAG laser (Eclipse Surgical Technologies, Palo Alto, CA) was utilized for thrombolysis and plaque ablation. Clinical success was achieved in 23/24 patients, with 23 patients (94%) surviving the acute infarction. Holmium:YAG laser is very effective and safe in thrombolysis and revascularization in this complicated clinical setting.

    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.

The data of the retrospective outpatient RECVAD registry (3690 patients who lived in Ryazan and its Region and had evidence in their outpatient medical records for one of the diagnoses, such as coronary heart disease, hypertension, chronic heart failure, atrial fibrillation, or their concurrence, were used. Forty­nine patients after acute myocardial infarction (AMI and/or percutaneous coro­ nary interventions (PCI with stenting ≤ 1 year before their inclusion in the registry, who were to undergo dual antiaggregant therapy (DAT according to current clinical guidelines (CG, were identified among 427 patients after AMI and/or PCI with coronary angioplasty. Contra­ indications to DAT were simultaneously revealed and a relationship of the use of therapy to their presence was compared. Results. Among the 49 patients who had indications for DAT that was used in 15 (30.6 % cases and that was not in 3 (6.1 % patients in the presence of contraindications, 25 (51.0 % did not receive DAT in the absence of contraindications and 6 (12.3 % patients received the therapy in the presence of contraindications. Conclusion. DAT prescribed by outpatient physicians does not always meet the current CG. There are cases of not using DAT in the presence of obvious indications for DAT and, on the contrary, those of its use in the presence of contraindications.

    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.

    Side branch occlusion may occur in the course of percutaneous transluminal coronary angioplasty (PTCA), particularly if complicated by site dissection. Concern that the additional placement of a stent may further jeopardize side branches is logical. Consequently, this study analyzed pre-PTCA, post-PTCA, poststent, and 6-month follow-up angiograms of 100 consecutive patients in whom 103 Gianturco-Roubin stents were implanted for acute or threatened closure after PTCA. Side branches were defined as major (> 50% of the stented vessel diameter) and minor ( 50% stenosis), and 129 minor branches were analyzed. Seven major branches (6%), all of which were diseased before PTCA, and 23 minor branches (18%) were lost after PTCA. Immediately after stent insertion, only 1 additional major and 1 minor branch were lost, whereas 2 of 7 major (29%) and 9 of 23 minor (39%) branches reappeared. At follow-up angiography, 7 major branches (6%) were more stenosed and 6 (6%) were improved compared with the angiogram before PTCA. Only 2 major (2%) and 5 minor (4%) branches remained occluded. Additionally, 2 major and 1 minor branch, which were patent after PTCA and stenting, were occluded at follow-up as a result of total occlusion of the stented segment.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7977091

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. 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.

    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.

    Both coronary artery perforation and intracoronary thrombus formation are life-threatening complications of percutaneous coronary interventions, which rarely occur simultaneously during angioplasty. We herein report a case of stent-related, left circumflex artery perforation, and subsequently acute left main artery thrombosis after the leakage was embolized with 7 microcoils. Intracoronary thromboectomy and systemic anticoagulant therapy were carefully used with good results. This case also represents some of our uncertainties regarding the best management of the patient.

    The evolution of the management of acute myocardial infarction (MI) has been one of the crowning achievements of modern medicine. At the turn of the twentieth century, MI was an often-fatal condition. Prolonged bed rest served as the principal treatment modality. Over the past century, insights into the pathophysiology of MI revolutionized approaches to management, with the sequential use of surgical coronary artery revascularization, thrombolytic therapy, and percutaneous coronary intervention (PCI) with primary coronary angioplasty, and placement of intracoronary stents. The benefits of prompt revascularization inspired systems of care to provide rapid access to PCI. This review provides a historical context for our current approach to primary PCI for acute MI.

    Percutaneous coronary angioplasty is well established therapeutic modality in the management of coronary artery disease. However, the high restenosis rate of 30 to 50% limits its usefulness. The principal mechanism of restenosis, intimal hyperplasia, is the proliferative response of vessel wall to injury, which consists largely of smooth muscle cells. A large body of animal investigations and a limited number of clinical studies have established the ability of ionizing radiation to reduce neointimal proliferation and restenosis rate significantly. Human studies have been reported that intravascular radiation after first restenosis inhibits a second restenosis. Encouraged by these reports, we are also conducting a double blind, placebo-controlled, randomized trial to evaluate this new therapeutic modality in patients with coronary artery stenosis. The objective of our trial is to determine the safety and efficacy of catheter-based solutional beta emitting radioisotope system in preventing restenosis after angioplasty. This review describes the vascular brachytherapy systems and isotopes that have been utilized in the initial clinical trials performed in this area of past PTCA coronary restenosis. The results of many worldwide ongoing clinical trials will determine whether this new technology will change the future practice of vascular intervention.

    Background The radiaI artery is currently regarded as a useful vascular access site for coronary procedures.This study was conducted to investigate the feasibility and safety of the percutaneous radial artery approach for angioplasty in the elderly.Methods Two thousand and fifty-eight consecutive patients (762 elderly,age≥65 years;and 1296 non-elderly,age <65 years,respectively) who underwent transradial coronary angioplasty were recruited in this study.Study endpoints included procedure success rate,procedure time,vascular complications at access site,and major adverse cardiac and cerebrovascular events during hospitalization.Results Elderly patients were more likely to present with unstable angina and renal dysfunction.The incidence of radial and brachiocephalic trunk anatomical tortuosity was higher in elderly patients than that in non-elderly patients (11.5% vs 3.7%;8.9% vs 2.6%,P<0.01,respectively).However,procedural success rate(94.7% vs 95.6%)and total mean procedure time ((67.9±27.3)minutes vs (58.6±38.5) minutes) for transradial coronary angioplasty were not significantly different between the two groups.Clinical course during the hospitalization was slightly worse in the elderly patients because of more adverse cardiac and cerebrovascular events after the procedure.However,the incidence of vascular complications was not significantly different between the elderly and non-elderly patients.Conclusion Although the incidence of radial and brachiocephalic trunk anatomical tortuosity is higher in elderly patients,transradial coronary intervention can be performed with similar safety and procedural success in these patients as compared with non-elderly patients.

  18. Risk assessment after coronary angioplasty with SPECT myocardial perfusion studies

    International Nuclear Information System (INIS)

    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

    Acute ST elevation myocarclial infarction has high mortality and morbidity rates.The majority of patients with this condition face erectile dysfunction in addition to other health problems,In this study,we aimed to investigate the effects of two different reperfusion strategies,primary angioplasty and thrombolytic therapy,on the prevalence of erectile dysfunction after acute myocardial infarction.Of the 71 patients matching the selection criteria,45 were treated with primary coronary angioplasty with stenting,and 26 were treated with thrombolytic agents.Erectile function was evaluated using the International Index of Erectile Function in the hospital to characterize each patient's sexual function before the acute myocardial infarction and 6 months after the event.The time required to restore blood flow to the artery affected by the infarct was found to be associated with the occurrence of erectile dysfunction after acute myocardial infarction.The increase in the prevalence of erectile dysfunction after acute myocardial infarction was 44.4% in the angioplasty group and 76.9% in the thrombolytic therapy group (P=0.008).In conclusion,this study has shown that reducing the time of reperfusion decreases the erectile dysfunction prevalence,and primary angioplasty is superior to thrombolytic therapy for decreasing the prevalence of erectile dysfunction after acute myocardial infarction.

    Coronary angioplasty and stent placement is associated with short hospital stays. Patients are expected to recover at home, alone, following limited care time with nurses. The purpose of the study was to describe participants' perceptions of recovery after angioplasty. Eight men and three women were interviewed 1 month after discharge from hospital. Verbatim transcripts were analysed for major themes using the qualitative techniques of grounded theory. Data analysis revealed three major categories: awareness of the problem, coping response and appraisal of the situation. These were linked via a problem solving process. In step one, the problem was identified. In step two, coping responses were taken to try and solve the problem. In step three, the results of the coping responses were appraised or evaluated. These categories were further defined by four phases identified as: pre-admission, admission, during the angioplasty and recovery. This paper describes the recovery phase. Awareness of the problem in the recovery phase was associated with 'relief from chest pain' for most participants. In contrast, anxiety continued and was associated with 'uncertainty over future health'. Participants described coping responses of "taking control of their life again" by undertaking both physical and psychological strategies. Finally, the situation was appraised to be either a 'good' or a 'bad' recovery. This appraisal was based on such considerations as the absence of chest pain, improvement in well-being and energy levels. The results of this study highlight patients' concerns and support the need for greater emphasis on their psychosocial needs. This care must be provided within the time constraints of short hospital stays. Nurses must also consider providing support to patients in the pre-admission and recovery phases.

    We performed 12-lead electrocardiographic monitoring in 97 patients during coronary angioplasty (PTCA) of a single vessel to correlate ischemic ST changes with clinical, angiographic and coronary hemodynamic variables and to determine the optimum lead or combination of leads for their detection. Ischemia (chest pain or ST change, group A) occurred in 79 patients (80%), but in only 15 of 23 patients (65%) with collaterals (p less than 0.05). Ischemia occurred more often in left anterior descending and left circumflex PTCA than right coronary PTCA, but pain was the only manifestation more often in left circumflex and right coronary PTCA. Ischemic ST change was silent in 16% and this proportion did not differ in clinical or angiographic groups except for diabetes with 3 of 5 (60%) having silent ischemia (p less than 0.05). Patients in group A (ischemia) compared to group B (no ischemia) had less severe lesions (85 +/- 9 vs 91 +/- 7%, p less than 0.01), higher transstenotic gradients (62 +/- 19 vs 53 +/- 9 mm Hg, p less than 0.05) and lower distal occluded pressures (24 +/- 11 vs 33 +/- 10 mm Hg, p less than 0.01), suggesting less collateral flow. Compared with a 12-lead electrocardiogram, the best single lead for detecting ST change during PTCA in each artery had a sensitivity of 80% and this increased to 93% using the best 2 leads. The best 3 leads (V3/III/V5 for left anterior descending and III/V2/V5 for right coronary and left circumflex) increased sensitivity to 100%.(ABSTRACT TRUNCATED AT 250 WORDS)

    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

    In 32 patients with successful percutaneous transluminal coronary angioplasty (PTCA), we performed treadmill exercise tests (TMET) before and about one month after PTCA to assess the correlation between the improvement in coronary artery lesions and exercise tolerance. Either the Bruce protocol (B: n = 12) or the modified Bruce protocol (MB: n = 20) was used; with the latter being applied to patients whose cardiac function seemed depressed. In 15 patients, oxygen consumption (VO2) was measured by analyzing the expired gases, 13 patients underwent exercise thallium-201 myocardial perfusion scintigraphy before and after PTCA, whose results were compared with those of TMET. In both B and MB protocols, the treadmill walking time was significantly prolonged after PTCA, compared to that before PTCA (B: 7.4 +/- 1.3 vs 9.5 +/- 1.9, MB: 11.4 +/- 3.5 vs 12.7 +/- 3.5 min). Heart rates (HR) and rate pressure products (RPP) were significantly increased after PTCA in both protocols (HR B: 139 +/- 18 vs 154 +/- 17, MB: 121 +/- 20 vs 137 +/- 19 bpm, RPP B: 26,500 +/- 5,600 vs 30,300 +/- 6,700, MB: 19,400 +/- 6,200 vs 22,700 +/- 6,600 mmHg.bpm), however, systolic blood pressure did not change significantly after PTCA in either protocol. While there was a significant improvement in VO2 after PTCA (21.6 +/- 6.3 vs 25.7 +/- 4.2 ml/kg/min), the O2-pulse remained unchanged. Thallium-201 myocardial scintigraphy revealed improvement of myocardial perfusion in 8 of the 13 cases examined.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1841916

    Objectives To understand the effect of carvedilol on the coronary vascular endothelial function of the patients with coronary heart disease after percutaneous transluminal coronary angioplasty (PTCA). Methods 51cases, having one or more than two branches narrow ( ≥ 70% ) , were diagnosed by coronary angiography. These patients were divided randomly into carvedilol group (n = 28 ) and control group (n = 23) who did not take carvedilol.Endothelin (ET) and nitro dioxide (NO) levels of peripheral blood were measured before and after PTCA,before and after two weeks by taking carvedilol. Results Compared with the ET and NO levels before PTCA, ET were markedly increased and NO were decreased after PTCA (p < 0.05); compared with the ET and NO levels before taking carvedilol, ET were decreased and NO were increased after two week (p <0.05) , but the ET and NO levels of the control group did not change in the period of two weeks observation (p > 0.05). Conclusions Carvedilol may improve the coronary vascular endothelial function after PTCA.

    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.

    BACKGROUND Coronary angiography is the gold standard method for diagnosis of coronary heart disease and usually performed by femoral approach that has several complications. To reduce these complications, upper extremity approach is increasingly used and is becoming preferred access site by many interventionists. Although radial approach is relatively well studied, safety, feasibility and risk of applying ulnar approach in not clearly known yet. METHODS We followed 97 patients (man = 56%, mean ± standard deviation of age = 57 ± 18) who had undergone coronary angiography or angioplasty via ulnar approach for 6-10 months and recorded their outcomes. RESULTS In 97 patients out of 105 ones (92.38%), procedure through ulnar access were successfully done. Unsuccessful puncture (3 patients), wiring (2 patients), passing of sheet (2 patients), and anatomically unsuitable ulnar artery (1 patient) were the reasons of failure. In 94 patients (89.52%), the angiography and angioplasty was done without any complications. Five patients (5.1%) hematoma and 11 patients (11%) experienced low-grade pain that resolved with painkiller. No infection, amputation or need for surgery was reported. CONCLUSION This study demonstrated that ulnar access in our patients was a safe and practical approach for coronary angiography or angioplasty, without any major complication. Bearing in mind its high success rate, it can be utilized when a radial artery is not useful for the catheterization and in cases such as prior harvesting of the radial artery (in prior coronary artery bypass grafting).

    Antiphospholipid syndrome is a disorder characterized by arterial and venous thromboses, thrombocytopaenia and stroke. Acute myocardial infarction is rarely associated with this syndrome. The treatment of these patients is a clinical challenge. This report is about a patient with antiphospholipid syndrome presenting with an acute myocardial infarction after an exercise test. The infarct-related coronary artery was successfully revascularized by primary angioplasty and stenting without any major bleeding complications. We think that the physical exertion could have favoured acute coronary thrombosis in this particular setting.

But at the same time, there exists the problem of restenosis (RS). After PTCA, RS rate can reach 30% to 50%, even with directstenting into the vessels, it still reaches 20% to 35%. So this affects long-term effect of interventional therapy, which directly relates to prognosis of patients with CHD and has been a hot spot of study in the field of preventing and treating CHD.

    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)

  10. Holmium:YAG laser angioplasty: treatment of acute myocardial infarction

    Topaz, On

    1993-06-01

    We report our clinical experience with a group of 14 patients who presented with acute myocardial infarction. A holmium:YAG laser was applied to the infarct-related artery. This laser emits 250 - 600 mJ per pulse, with a pulse length of 250 microseconds and repetition rate of 5 Hz. Potential benefits of acute thrombolysis by lasers include the absence of systemic lytic state; a shortened thrombus clearing time relative to using thrombolytics; safe removal of the intracoronary thrombus and facilitation of adjunct balloon angioplasty. Potential clinical difficulties include targeting the obstructive clot and plaque, creation of debris and distal emboli and laser-tissue damage. It is conceivable that holmium:YAG laser can be a successful thrombolytic device as its wave length (2.1 microns) coincides with strong water absorption peaks. Since it is common to find an atherosclerotic plaque located under or distal to the thrombotic occlusion, this laser can also be applied for plaque ablation, and the patient presenting with acute myocardial infarction can clearly benefit from the combined function of this laser system.

    The purpose of the study was to compare long-term results of angioplasty and coronary arterial stenting (CAS) depending on the initial degree of coronary arterial (CA) lesion according to morphological stenosis classification, as well as to evaluate the influence of re-stenosis on myocardial contractility dynamics, anginal recurrence rate, and exercise tolerance. The subjects, 228 men after angioplasty and 184 men after CAS with wire stents without drug coating, were included in the study between 1989 and 2005. Coronarography was repeated in 358 patients one year after surgery. The patients were divided into two groups. The first group consisted of 161 patients, to who 180 stents were implanted. The second group consisted of 197patients, in who 226 angioplasty procedures were performed. Data were processed using standard variational statistical methods, i.e. the calculation of mean values and standard deviation. Statistical calculations were carried out using Analysis ToolPak- VBA software of Microsoft Excel 2000. The study found that one year after either intervention the number of patients without anginal symptoms fell significantly compared with this number during the in-hospital period. In group 2 the frequency of restenosis was higher and the number of patients with anginal symptoms was significantly bigger than in group 1; the number of asymptomatic patients was significantly bigger in group 1. Initial morphological characteristics of CA lesion had a significant effect on the long-term frequency of restenosis following endovascular treatment. Restenosis was 2 to 2.5 times more frequent in patients with C type CA lesion vs. patients with A type regardless the method of endovascular intervention. The results of the study demonstrate the importance of taking into account initial morphological characteristics of CA lesion; CAS is more preferable than angioplasty, especially in patients with C type CA lesion.

The present study evaluated results of PTCA of left anterior descending artery (LAD six months after PTCA, by combining transthoracic Doppler coronary flow reserve (CFR and color Tissue Doppler (C-TD dobutamine stress. Six months after PTCA of LAD, 24 men, free of angiographic evidence of restenosis, underwent standard Doppler-echocardiography, transthoracic CFR of distal LAD (hyperemic to basal diastolic coronary flow ratio and C-TD at rest and during dobutamine stress to quantify myocardial systolic (Sm and diastolic (Em and Am, Em/Am ratio peak velocities in middle posterior septum. Patients with myocardial infarction, coronary stenosis of non-LAD territory and heart failure were excluded. According to dipyridamole g-SPECT, 13 patients had normal perfusion and 11 with perfusion defects. The 2 groups were comparable for age, wall motion score index (WMSI and C-TD at rest. However, patients with perfusion defects had lower CFR (2.11 ± 0.4 versus 2.87 ± 0.6, p m at high-dose dobutamine (p m of middle septum (r = 0.55, p In conclusion, even in absence of epicardial coronary restenosis, stress perfusion imaging reflects a physiologic impairment in coronary microcirculation function whose magnitude is associated with the degree of regional functional impairment detectable by C-TD.

    This study sought to quantitatively evaluate the reduction of radiation dose in coronary angiography and angioplasty with the use of image noise reduction technology in a routine clinical setting. Radiation dose data from consecutive 605 coronary procedures (397 consecutive coronary angiograms and 208 consecutive coronary interventions) performed from October 2014 to April 2015 on a coronary angiography system with noise reduction technology (Allura Clarity IQ) were collected. For comparison, radiation dose data from consecutive 695 coronary procedures (435 coronary angiograms and 260 coronary interventions) performed on a conventional coronary angiography system from October 2013 to April 2014 were evaluated. Patient radiation dosage was evaluated based on the cumulative dose area product. Operators and operator practice did not change between the 2 evaluated periods. Patient characteristics were collected to evaluate similarity of patient groups. Image quality was evaluated on a 5-grade scale in 30 patients of each group. There were no significant differences between the 2 evaluated groups in gender, age, weight, and fluoroscopy time (6.8 ± 6.1 vs 6.9 ± 6.3 minutes, not significant). The dose area product was reduced from 3195 ± 2359 to 983 ± 972 cGycm(2) (65%, p noise reduction technology. Image quality was graded as similar between the evaluated systems (4.0 ± 0.7 vs 4.2 ± 0.6, not significant). In conclusion, a new x-ray technology with image noise reduction algorithm provides a substantial reduction in radiation exposure without the need to prolong the procedure or fluoroscopy time.

    Restenosis occurs to be an Achilles heel of coronary interventions. Three overlapping processes: elastic recoil, neointimal proliferation and arterial remodelling are responsible for development of arterial renarrowing. The only method which proved efficient in reducing the restenosis rate is coronary stenting. Stents deployed using high pressure technique diminish restenosis rate by about one third. Stents eliminate elastic recoil and arterial remodelling but aggravate neointimal proliferation. A concept of radiation therapy was introduced to solve the problem of neointimal hyperplasia. Experiments on animal models of restenosis proved that both gamma as well as beta irradiation inhibited neointimal proliferation after arterial injury. Results of experimental investigations concerning both intraarterial irradiation during angioplasty as well as radioactive stent implantation are reviewed. Authors discuss also results of first clinical trials, the design and preliminary results of some larger studies like PARIS, SCRIPPS, GENEVA, BERT, IRIS, WRIST. Further investigational directions in intravascular radiation therapy are also presented. PMID:9591455

    We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event.

    Preserved thrombolysis in myocardial infarction (TIMI) flow before percutaneous coronary intervention (PCI) in acute myocardial infarction is related to improved outcome. Gated single-photon emission computed tomography (SPECT) allows the simultaneous assessment of left ventricular perfusion and function. We evaluated the initial risk area and subsequent evolution of perfusion and function according to TIMI flow before successful primary PCI. In 36 patients, treated with abciximab, primary PCI and stenting, {sup 99m}Tc-sestamibi was injected before PCI and gated SPECT acquired thereafter. Gated SPECT was repeated 7 and 30 days later. Perfusion defect, wall motion score index, left ventricular ejection fraction and volumes were examined. Before PCI, 14 patients (group A) showed TIMI flow 2-3 and 22 (group B) TIMI flow 0-1, but no differences in clinical variables, initial risk area, wall motion score, ejection fraction or volumes. Perfusion defect was smaller in group A at 7 (9%{+-}11% vs 19%{+-}14%, p<0.02) and 30 days (7%{+-}7% vs 16%{+-}12%, p<0.02) and the salvage index was higher at 30 days (77%{+-}22% vs 55%{+-}28%, p<0.02). Wall motion score was lower in group A at 30 days (p<0.05). Ejection fraction significantly improved in both groups at 7 and 30 days. End-diastolic volume showed a trend towards a reduction in group A, whilst it was significantly increased in group B. Conversely, end-systolic volume was significantly decreased in group A but remained unchanged in group B. In the setting of optimal myocardial reperfusion for myocardial infarction, preserved TIMI flow before PCI does not limit the initial risk area but it does improve myocardial salvage and functional recovery.

In 42% of cases 6-minute walk test increased to 3 times; The NYHA class decreased by 2 classes (group 1. In 28 cases 6-minute walk test increased to 2 times and the NYHA class decreased on 1 class. In 22 patients 6-minute walk test increased less than 50% of reference values and there was no dynamics NYHA class (50 patients of the group 2. Initial extent of LV global perfusion defects in group 1 – 41,2 ± 4,0%, in group 2 – 58,3 ± 2,4% (р = 0,0004. Similar values are received for perfusion indicators in the area of LAD and the LV apex. Prevalence of myocardial perfusion defects at rest reflects prevalence of a cardiosclerosis in a cardiac muscle. Conclusion. Degree of LV myocardial perfusion defects in patients with the expressed heart failure of ischemic etiology is the key indicator influencing clinical efficiency of coronary angioplasty. Critical size for definition of the favorable forecast of revascularization are 60% and more perfusion defects testifying that in a cardiac muscle the focal cardiosclerosis prevails over the functioning myocardium. 

  2. Gene Therapy for the Prevention of in- Stent Restenosis Post Coronary Angioplasty

    Full Text Available Around the world, Coronary Artery Disease (CAD is quickly becoming the most common cause of morbidity and mortality. Percutaneous coronary interventions- angioplasty and stent insertion- have proved effective and reliable treatments for CAD but their long-term efficacy is limited by the high rate of restenosis. This occurs in 30 – 50% of patients undergoing angioplasty and results in symptoms requiring repeat intervention in up to 75% of them. Stent insertion has been shown to reduce this rate but in-stent restenosis still occurs in 20-40% of cases. The high incidence of restenosis represents a large economic burden on health resources. As a consequence of the resistance of restenosis to traditional therapeutic approaches, gene therapy has emerged an attractive potential therapy for this problem. Excessive extracellular matrix (ECM deposition in the neointima is the main mechanism leading to luminal loss after coronary stenting. Transforming growth factor-β (TGF-β is a major regulator of ECM deposition and there is substantial evidence to suggest its role in restenosis. TGF-β1 is the predominant isoform in vascular tissues and its production is observed to be upregulated in human restenotic lesions and in the intima of injured animal vessels. The aim of this study is to develop, investigate and compare the effects of two potentially therapeutic recombinant, replication-deficient adenoviruses, which will give rise to the expression of transgenic proteins which antagonise the fibrogenic effects of TGF-β1 in coronary arteries post stent insertion. The cDNA for these proteins have each been inserted into replication deficient adenovirus vectors under the control of the Major Immediate/Early Murine Cytomegalovirus (MIEmCMV promoter. Virus identity and the presence of transgenes have been confirmed by restriction analysis and Southern blotting respectively. Efficient transgene expression has been confirmed in cultured porcine coronary vascular

    Congenital occlusion of the left main coronary trunk is a life-threatening abnormality, and its optimal management remains controversial. This report describes a case of successful patch angioplasty with auto-pulmonary artery for a 12-year-old boy with congenital left main trunk occlusion. We divided the main pulmonary artery, harvested a pulmonary artery wall strip, and performed patch angioplasty of the occluded left main trunk ostium. We were able to clearly expose the left main trunk behind the pulmonary artery because the obstruction was divided for the patch material. The postoperative course was uneventful, and coronary angiography at 4 months after surgery showed excellent patency of the left main trunk. The auto-pulmonary arterial wall was easy to handle during angioplasty, and its favorable durability has been established both in the Ross procedures and in an arterial switch procedure. Therefore, we conclude that patch angioplasty using a piece of the pulmonary arterial wall represents a good alternative to conventional coronary artery bypass grafting.

    We report a case of acute stent recoil occurring after the stenting of an ostial left main coronary artery lesion. The marked recoil after high-pressure balloon inflation confirmed that the radial force of the first stent was unable to ensure vessel patency. The addition of a second stent provided the necessary support to achieve a good final result. This case illustrates a possible complication of aorto-ostial angioplasty that could be treated with double stenting. PMID:12499528

    The authors studied changes of LV dP/dt during transcutaneous coronary angioplasty (TCA). The aim of the study was to detect the alterations of LV function during coronary occlusion and to evaluate the immediate effects of PCA on myocardial function. Six patients with incapacitating angina and isolated left anterior descending disease were successfully treated by TCA using Gruntzig's technique. The study protocol included several recording sequences per patient during the phases of balloon inflation at progressively increasing pressures from 2 to 10 hours. Each sequence comprised a recording under basal conditions and every 5 seconds during inflation (20 seconds) and deflation (45 seconds) of the following parameters: heart rate, aortic and LV pressures, positive and negative peaks of LV dP/dt, and the intracoronary pressure gradient at the beginning and the end of each sequence. The first part of the results based on 27 recorded sequences analysed the bad effects of myocardial ischaemia; coronary occlusion induced a significant fall (p less than 0.01) in the positive and negative peak dP/dt values and on elevation (p less than 0.01) in LV end diastolic pressure, without affecting LV systolic pressure or heart rate. These changes have the following characteristics: they are early, occurring within seconds of coronary occlusion; they affect LV contraction and relaxation simultaneously, but the effects are more marked on LV relaxation; the severity is proportional to the duration of occlusion; they are totally reversible; the disturbances of relaxation return to normal more quickly than those of contraction.(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective Accelerated left main coronary stenosis (LMCS) is a known potential late complication of coronary artery catheter procedures. The aim of this study was to assess the current occurrence of LMCS as a delayed complication of percutaneous angioplasty (PTCA) of the left coronary branches in our institution. Methods The medical records of patients referred for coronary artery by-pass surgery from the same Cardiology Unit in the January 2003 to December 2006 period and presenting a significant (> 50%) LMCS as a new finding following a PTCA of the left coronary artery branches, were reviewed. Patients with retrospective evidence of any LMCS at previous coronary angiographies preceding the percutaneous procedure were excluded. Results Thirty-seven patients (5 females, mean age 71.1±8.6 years) out of 944 (4%) having undergone a PTCA, fulfilled the inclusion criteria, 19 (51%) after a procedure also involving the LAD coronary artery. Extraback-up guiding catheters were used in most cases. Use of multiple wires or balloons was observed in 3 cases (8%). Rotablator and proximal occlusion device were used in one case respectively (3%). Twenty patients (54%) have had more than one percutaneous coronary intervention on the left coronary branches. The mean time elapsed from the first angioplasty and surgical intervention was 18.1±7.8 months. Conclusions The potential occurrence of LMCS following a percutaneous intervention procedure, especially when complicated and repeated, should not be underestimated in the current era. This evidence may offer the rationale to schedule non-invasive imaging tests to monitor left main coronary patency after the procedure as well as to fuel further research to develop less traumatic materials.

    Full Text Available Anemia is associated with high mortality and poor prognosis after acute coronary syndrome (ACS. Increased red cell distribution width (RDW is a strong independent predictor for adverse outcomes in ACS. The common underlying mechanism for anemia and increased RDW value is iron deficiency. It is not clear whether serum iron deficiency without anemia affects left ventricular (LV performance after primary angioplasty for acute myocardial infarction (AMI. We investigated the prognostic value of serum iron concentration on LV ejection fraction (EF at 6 months and its relationship to thrombolysis in myocardial infarction (TIMI risk score in post MI patients.We recruited 55 patients who were scheduled to undergo primary coronary balloon angioplasty after AMI and 54 age- and sex-matched volunteers. Serum iron concentration and interleukin-6 levels were measured before primary angioplasty. LVEF was measured by echocardiography at baseline and after 6 months. TIMI risk score was calculated for risk stratification.Serum iron concentration was significantly lower in those in whom LVEF had not improved ≥ 10% from baseline (52.7 ± 24.1 versus 80.8 ± 50.8 µg/dl, P = 0.016 regardless of hemoglobin level, and was significantly lower in the AMI group than in the control group (62.5 ± 37.7 versus 103.0 ± 38.1 µg/dl, P<0.001. Trend analysis revealed that serum iron concentration decreased as TIMI risk score increased (P = 0.002. In addition, lower serum iron concentrations were associated with higher levels of inflammatory markers. Multiple linear regression showed that baseline serum iron concentration can predict LV systolic function 6 months after primary angioplasty for AMI even after adjusting for traditional prognostic factors.Hypoferremia is not only a marker of inflammation but also a potential prognostic factor for LV systolic function after revascularization therapy for AMI, and may be a novel biomarker for therapeutic intervention.

    A 24-year-old healthy man consulted to our center because of typical on-and-off chest-pain and an electrocardiogram showing ST-segment elevation in inferior leads. An urgent coronary angiography showed angiographically normal coronary arteries. Cardiovascular magnetic resonance imaging confirmed acute myocarditis. Although acute myocarditis triggering coronary spasm is an uncommon association, it is important to recognize it, particularly for the management for those patients presenting with ST-segment elevation and suspect myocardial infarction and angiographically normal coronary arteries. The present report highlights the role of cardiovascular magnetic resonance imaging to identify acute myocarditis as the underlying cause.

    Patients with diabetes mellitus (DM) have more severe CAD and higher mortality in acute coronary syndrome (ACS) than patients without DM. The optimal mode of revascularization-coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)-remains controversial in this setting. For patients with DM and ST-segment elevation myocardial infarction, prompt revascularization of the culprit artery via PCI is generally preferable. In non-ST-elevation ACS, the decision on mode of revascularization is more challenging. Trials comparing CABG with percutaneous transluminal coronary angioplasty, bare metal stents, and first-generation drug-eluting stents in DM patients with multivessel have demonstrated decreased mortality in those receiving CABG. On the other hand, trials and retrospective analyses comparing CABG to PCI with second-generation drug-eluting stents have not shown a statistically significant mortality benefit favoring CABG. This potentially narrowed that gap between CABG and PCI requires further investigation. PMID:27339854

    Full Text Available The percutaneous transluminal coronary angioplasty (PTCA is one of the interventional procedures which impart high radiation doses to patients compared to the other cardiologic procedures. This study intends to audit and optimize radiation dose imparted to patients undergoing PTCA. Forty-four patients who underwent PTCA involving single or multiple stent placement guided under cardiovascular X-ray machine were included in the study. Radiation doses were measured using dose area product (DAP meter for patients undergoing single and multiple stent placements during PTCA. A dose reduction of 27-47% was achieved using copper filters and optimal exposure parameters. The mean DAP values before optimization were 66.16 and 122.68 Gy cm 2 for single and multiple stent placement respectively. These values were 48.67 and 65.44 Gy cm 2 respectively after optimization. In the present scenario, due to the increase in the number of PTCAs performed and the associated risk from radiation, periodical audit of radiation doses for interventional procedures are recommended.

    It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS). Fifteen patients older than 65 years with ACS within 24 hours of the event were admitted from April 4, 2004 to December 12, 2005. All the patients had early percutaneous coronary intervention and were followed up for 6-12 months by telephone or in the out-patient department. Nine of the 15 patients exhibited acute myocardial infarction (AMI). Six exhib-ited unstable angina (UA). All the patients had early PCI. The average door-to-balloon time was 78 minutes (40-110 minutes). The average PCI time was 99 minutes (68-120 minutes). Nineteen of 36 lesions in the fifteen angioplasty patients were treated and 20 stents were implanted in total. All the procedures were considered successful. Neither deaths nor recurrent angina occurred in the 6-12 months of follow-up. It was shown that early PCI might be an effective and safe method to treat eld-erly patients with ACS.

    Coronary artery disease (CAD) is a major cause of mortality internationally and in Pakistan. Angioplasty has been proven to be an effective treatment for CAD. Stent thrombosis is a known but preventable complication of angioplasty. Several factors may lead to stent thrombosis with non-compliance with the prescribed drug regimen, being one of the most important factors. We report a case of stent thrombosis after four months of angioplasty. After exploring of patient's post angioplasty routines, it was found that the patient was non-compliant with the prescribed anti- platelets and other prescribed drugs. This time the patient presented with another acute myocardial infarction, and he went through angioplasty again.

    Periodontitis is a chronic, bacterially-induced inflammatory disease of the tooth-supporting tissues, which may result in transient bacteremia and a systemic inflammatory response. Periodontitis is associated with coronary artery disease independently of established cardiovascular risk factors, 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. Despite elimination of extraction and purification steps, and demonstration of sensitivity levels of 25-125 colony forming units (CFU), we did not detect bacterial DNA from any of the coronary angioplasty balloons. A subsequent questionnaire indicated that the prevalence of periodontitis in the study cohort was at least 39.5%. Although coronary angioplasty balloons are unlikely to be useful for detection of bacteria with current PCR techniques in unselected patients with coronary artery disease, more studies are warranted to determine the extent to which bacteria contribute to atherosclerosis and its clinical manifestations and whether the presence of bacteria in the arteries is a transient phenomenon.

    During the early years of coronary interventions a rigorous on-site surgical stand-by was mandatory. The increased experience in coronary angioplasty both on total number of procedures and the experience gained by each operator, together with the technical improvements, namely since the introduction of stents has induced an evolution in the stand-by strategy, with new concepts such as "next available operating room" or coronary interventions "without on site" surgical facilities, are gaining widespread acceptance. With the aim of defining the requirements to perform coronary interventions at hospitals without coronary surgery, the following aspects are reviewed: a) complications following coronary angioplasty that require coronary surgery; b) the current status of coronary angioplasty without surgical stand-by in different countries. All this information allows us to advance some recommendations concerning the performance of coronary interventions at hospitals without on-site cardiac surgery. Different issues including hospital characteristics, operator and cardiac catheterization laboratory requirements, as well as lesion characteristics and the type of informed consent, should be taken into account.

    Twelve cases of myocardial infarction as related to strenuous exertion are presented with the pathological findings in several of these cases. Three cases with coronary arteriography are also presented. The pathology of coronary arteriosclerotic plaques and the vulnerability to acute injury is reviewed and discussed. It is concluded that strenuous exertion can cause acute injury to coronary artery plaques due to the unusual stressful whip-like action to which coronary arteries are subject. These injuries may initiate as cracks in the plaques or subintimal hemorrhages and proceed to coronary occlusion and ultimate myocardial infarction. With this concept in mind we use the term of "crack in the plaque" (Black's Crack in the Plaque) to account for the sudden appearance of clinical coronary artery disease appearing during or shortly after exertion, or other stressful situations in patients without previous existing evidence of clinical coronary artery disease. This could also account for exacerbation of symptoms or death occurring after exertion in previously quiescent asymptomatic known coronary artery disease subjects. This concept may explain some of the puzzling features of coronary disease.

    Abstract Exogenous administration of coenzyme Q10 (CoQ10) has been shown in experimental models to have a protective effect against ischemia–reperfusion injury. However, it is unclear whether follow-up plasma CoQ10 concentration is prognostic of left ventricular (LV) performance after primary balloon angioplasty in patients with acute ST segment elevation myocardial infarction (STEMI). We prospectively recruited 55 patients with STEMI who were treated with primary coronary balloon angioplasty. Plasma CoQ10 concentrations were measured before primary angioplasty (baseline) and 3 days, 7 days, and 1 month after STEMI using high-performance liquid chromatography. Echocardiography was performed at baseline and at 6-month follow-up. The control group comprised 54 healthy age- and sex-matched volunteers. Serial circulating CoQ10 concentrations significantly decreased with time in the STEMI group. The LV ejection fraction at 6-month follow-up positively correlated with the 1-month plasma CoQ10 tertile. Higher plasma CoQ10 concentrations at 1 month were associated with favorable LV remodeling and systolic function 6 months after STEMI. Multiple linear regression analysis showed that changes in CoQ10 concentrations at 1-month follow-up were predictive of LV systolic function 6 months after STEMI. Changes in CoQ10 concentrations correlated negatively with baseline oxidized low-density lipoprotein and fibrinogen concentrations and correlated positively with leukocyte mitochondrial copy number at baseline. Patients with STEMI who had higher plasma CoQ10 concentrations 1 month after primary angioplasty had better LV performance at 6-month follow-up. In addition, higher plasma CoQ10 concentration was associated with lower grade inflammatory and oxidative stress status. Therefore, plasma CoQ10 concentration may serve as a novel prognostic biomarker of LV systolic function after revascularization therapy for acute myocardial infarction. PMID:27495100

    Full Text Available Abstract Background Multiples indices have been described using tissue Doppler imaging (DTI capabilities. The aim of this study was to assess the capability of one or several regional DTI parameters in separating control from ischemic myocardium. Methods Twenty-eight patients with acute myocardial infarction were imaged within 24-hour following an emergent coronary angioplasty. Seventeen controls without any coronary artery or myocardial disease were also explored. Global and regional left ventricular functions were assessed. High frame rate color DTI cineloop recordings were made in apical 4 and 2-chamber for subsequent analysis. Peak velocity during isovolumic contraction time (IVC, ejection time, isovolumic relaxation (IVR and filling time were measured at the mitral annulus and the basal, mid and apical segments of each of the walls studied as well as peak systolic displacement and peak of strain. Results DTI-analysis enabled us to discriminate between the 3 populations (controls, inferior and anterior AMI. Even in non-ischemic segments, velocities and displacements were reduced in the 2 AMI populations. Peak systolic displacement was the best parameter to discriminate controls from AMI groups (wall by wall, p was systematically Conclusion DTI-analysis appears to be valuable in ischemic heart disease assessment. Its clinical impact remains to be established. However this simple index might really help in intensive care unit routine practice.

    Acute coronary syndrome (ACS) is caused by a critical obstruction of a coronary artery because of atherosclerotic coronary artery disease. Three specific conditions are included: ST elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. The ST segment on the electrocardiogram is a sensitive and specific marker of myocardial ischemia and infarction; however, ST segment deviation is regional not global, thus the ECG lead must be placed over the affected region of the myocardium. This article describes ACS and infarction and the use of ST segment monitoring to detect these conditions. PMID:27484662

    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.

    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.

    This review focuses on the modern management of the non-ST elevation acute coronary syndromes (unstable angina and non-ST elevation myocardial infarction). Patients with these syndromes are at varying degrees of risk of (re)infarction and death. This risk can be reliably predicted by clinical, electrocardiographic, and biochemical markers. Aspirin, clopidogrel, heparin (unfractionated or low molecular weight), and anti-ischaemic drugs should be offered to all patients, irrespective of the predicted level of risk. Patients at high risk should also receive a glycoprotein IIb/IIIa receptor inhibitor and should undergo early coronary arteriography with a view to percutaneous or surgical revascularisation. Lower risk patients should undergo non-invasive testing. When inducible myocardial ischaemia is exhibited coronary arteriography should follow. When non-invasive testing is negative, a conservative management strategy is safe. PMID:15811883

    @@ Coronary artery bypass grafting (CABG) is considered as a more complete means of revascularization than percutaneous coronary intervention (PCI). However, acute coronary syndrome (ACS) can still occur after CABG. The culprit vessel can be the graft vessel or the native vessel. Many questions remain unanswered in the Chinese literature regarding this topic: what are the short- and long-term pathological changes that induce ACS? Is there any difference between arterial and venous grafts with respect to the frequency of restenosis? Are there any patterns of ACS-related vessels in different periods after CABG? We aim to answer these fundamental questions by analyzing coronary angiographies of patients with recurrent ACS following CABG and provide evidence for reducing post-CABG restenosis.

    Full Text Available Background : Vertebral artery ostial stenosis (VAOS is one of the most frequent causes of posterior circulation stroke. Percutaneous angioplasty and stenting (PTAS is one of the treatment modalities. Patients and Methods : This is a longitudinal observational study from September 2006 to February 2009, conducted at hospitals affiliated with the Shiraz University of Medical Sciences, Shiraz, southern Iran. The patient cohort included patients with posterior circulation stroke or transient ischemic attack (TIA and more than 70% VAOS, and patients with asymptomatic VAOS of more than 70% and aplasia or total occlusion of the contralateral VA or subclavian artery. All the patients underwent PTAS with balloon-mounted bare coronary stents. Technical success, procedural complications, composite outcomes of death, stroke or TIA in the vertebrobasilar territory during the first 30 days, stroke or TIA in the vertebrobasilar territory, and restenosis during follow-up, were assessed. Results : During the study period, 81 patients (mean age 68 + 8.9 years, 63 (78% males, 71 symptomatic and 18 asymptomatic underwent the procedure. Technical success was achieved in 88 (99% patients. Procedure-related complications, other than puncture site complications, were seen in two patients (2.2%. The composite outcome of death, stroke or TIA in the vertebrobasilar territory during the first 30 days was 1%. None of the patients had clinical recurrence or restenosis during the follow-up (mean follow-up 14 months. Conclusion : Percutaneous transluminal angioplasty and stenting of the proximal VA was feasible and safe. The risk of restenosis should be analyzed in long-term studies with angiographic follow-up.

    In 10 % of patients, who suffer an acute coronary syndrome (ACS), a major cardiovascular event occurs despite optimal therapy. The occlusion of the vessel is driven by atherothrombosis, which arises from platelet activation and activation of the coagulation cascade. In the last decade the secondary prevention continuously improved by development of dual anti-platelet therapy with new P2Y12-inhibitors such as clopidogrel, prasugrel, and ticagrelor. Until recently, the coagulation cascade was not targeted in secondary prevention. The coagulation factor Xa plays a crucial role in thrombosis and is elevated in patients after acute coronary syndrome, therefore representing an attractive target for novel therapies in ACS. Former studies with vitamin K antagonists showed reduction of cardiovascular events but increased major bleedings. Two phase-3 trials investigated the role of novel oral anticoagulant agents on top of aspirin and clopidogrel in patients with ACS. The APPRAISE-2 study, which tested the oral factor Xa inhibitor apixaban was prematurely terminated because of an increase of major bleedings in the absence of an effect on cardiovascular events. In contrast, the ATLAS ACS2 TIMI-51 trial interrogating the oral factor Xa inhibitor rivaroxaban in a low dose regimen showed significant reduction of cardiovascular events as well as total mortality. Thus, add-on treatment with low dose rivaroxaban emerged as a new option for patients with ACS. This review illustrates recent advances in the development of antithrombotic therapy in acute coronary syndromes, provides guidance on which patients should receive which therapy for secondary prevention of events, and points out potentially fruitful new strategies for the future of antithrombotic treatment in ACS.

    Objective To summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.Data sources A literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.Study selection Well-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.Data extraction Data and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.Data synthesis Inflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.Conclusions Inflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin Ⅱ receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein Ⅱb/Ⅲa receptor antagonists, mechanical intervention strategies, etc).

    Objectives To investigate the value of rotational coronary angiography (RoCA) in the context of percutaneous coronary intervention (PCI) planning. Background As a diagnostic tool, RoCA is associated with decreased patient irradiation and contrast use compared with conventional coronary angiography (CA) and provides superior appreciation of three‐dimensional anatomy. However, its value in PCI remains unknown. Methods We studied stable coronary artery disease assessment and PCI planning by interventional cardiologists. Patients underwent either RoCA or conventional CA pre‐PCI for planning. These were compared with the referral CA (all conventional) in terms of quantitative lesion assessment and operator confidence. An independent panel reanalyzed all parameters. Results Six operators performed 127 procedures (60 RoCA, 60 conventional CA, and 7 crossed‐over) and assessed 212 lesions. RoCA was associated with a reduction in the number of lesions judged to involve a bifurcation (23 vs. 30 lesions, P RoCA improved confidence assessing lesion length (P = 0.01), percentage stenosis (P = 0.02), tortuosity (P RoCA augments quantitative lesion assessment, enhances confidence in the assessment of coronary artery disease and the precise details of the proposed procedure, but does not affect X‐ray dose, contrast agent volume, or procedure duration. © 2015 Wiley Periodicals, Inc.

    Acute coronary syndrome (ACS) is a major cause of morbidity and mortality worldwide. New serological biomarkers, such as troponins, have improved the diagnosis of ACS; however, the diagnosis of ACS can still be difficult as there is marked heterogeneity in its presentation and significant overlap with other disorders presenting with chest pain. Evidence is accumulating that cardiac MRI provides information that can aid the detection and differential diagnosis of ACS, guide clinical decision-making and improve risk-stratification after an event. In this review, we present the relevant cardiac MRI techniques that can be used to detect ACS accurately, provide differential diagnosis, identify the sequelae of ACS, and determine prognostication after ACS.

    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).

    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.

    Full Text Available Abstract Background In terms of clinical and angiographic findings, multiple simultaneous coronary occlusions in acute myocardial infarction are infrequent, and the mechanism of the occlusions is unclear. Case presentation We herein report a rare case of two simultaneously occluded coronary arteries, one of which subsequently underwent spontaneous lysis. An 88-year-old man had a 3-hour attack of acute crushing retrosternal chest pain. His first electrocardiogram showed ST-segment elevation in the inferior (II, III, and aVF and anterior (V3–V6 leads. His second electrocardiogram in the cardiac care unit showed ST-segment elevation in the inferior leads but ST-segment depression in the anterior leads. Emergency coronary angiography revealed that the right coronary artery was acutely and totally occluded at the midportion and that the proximal and midportion of the left anterior descending coronary artery had an acute thrombus. According to his electrocardiogram and coronary angiography findings, we inferred that the right coronary artery and left anterior descending coronary artery first totally occluded simultaneously, and then the thrombus in the left anterior descending coronary artery spontaneously underwent partial lysis. Therefore, intervention of the right coronary artery was performed followed by injection of glycoprotein IIB-IIIA inhibitor into the left anterior descending coronary artery. He had an uneventful hospital course and was discharged home 10 days later. Conclusion Because patients with multivessel coronary artery occlusion are often in serious condition, abnormal electrocardiographic results must be identified and affected vessel should be opened timely and efficiently to save the myocardium and reduce complications such as congestive heart failure.

    Full Text Available Cardiovascular abnormalities are well-known manifestations of tertiary syphilis infections which although not frequent, are still causes of morbidity and mortality. A less common manifestation of syphilitic aortitis is coronary artery ostial narrowing related to aortic wall thickening. We report a case of a 46-year-old male admitted due to acute anterior ST elevation myocardial infarction submitted to primary percutaneous coronary intervention successfully. Coronary angiography showed a suboccluded ostial lesion of left main coronary artery. VDRL was titrated to 1/512. The patient was discharged with treatment including benzathine penicillin. Previous case reports of acute myocardial infarction in association with syphilitic coronary artery ostial stenosis have been reported, but the fact that the patient was treated by percutaneous coronary intervention is unique in this case.

    To determine the frequency of risk factors in male patients presenting with acute coronary syndrome. Study Design: Observational study. Place and Duration of Study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008. Methodology: Male patients with acute coronary syndrome were included in this study. Patients having angioplasty (PCI), coronary artery bypass surgery, chronic liver and kidney diseases were excluded. Presence of diabetes, smoking, hypertension, dyslipidemia, physical activity, stress, a family history of coronary artery disease (CAD) and medication was documented. Blood pressure, ECG, cardiac enzymes, fasting blood glucose, lipid profile and echocardiography were done within 24 hours of admission. Body mass index and waist circumference were measured. Data was analysed using SPSS-15. Results: A total of 135 male patients of ACS were studied having mean age of 54.26+-11.60 years. Maximum number of patients aged between 51 to 60 years, (n = 41, 31.9%). STEMI (ST-elevation myocardial infarction) was diagnosed in 96 (71.1%) patients, non-STEMI in 12 (8.9%) while 27 (20%) patients were having unstable angina. Smoking was documented in 60 (44%) patients, hypertension in 50 (37%), diabetes in 34 (25.2%) and a family history of premature CAD was recorded in 24 (17.8%) patients. Fifty one (37.8%) patients were overweight (BMI = 25-29.9) while 22 (16.3%) were obese (BMI greater or equal to 30). Waist circumference > 90 cm was found in 86 (63.6%) subjects. Sixty four (47.4%) patients were active physically. Psychosocial stress was documented in 33 (23.75). Hypertension, diabetes and dyslipidemia were the most frequent combinations, observed in 24 (17.9%) subjects. Conclusion: Dyslipidemia, smoking, hypertension and diabetes were most frequent risk factors. Public awareness to control risk factors can reduce the prevalence of CAD. (author)

    Abnormal blood flow patterns promoting inflammation, cellular proliferation, and thrombosis may be established by local changes in vessel geometry after stent implantation in bifurcation lesions. Our objective was to quantify altered hemodynamics due to main vessel (MV) stenting and subsequent virtual side branch (SB) angioplasty in a coronary bifurcation by using computational fluid dynamics (CFD) analysis. CFD models were generated from representative vascular dimensions and intravascular ultrasound images. Time-averaged wall shear stress (TAWSS), oscillatory shear index (OSI), and fractional flow reserve (FFR) were quantified. None of the luminal surface was exposed to low TAWSS (stenting introduced eccentric areas of low TAWSS along the lateral wall of the MV. Virtual SB angioplasty resulted in a more concentric region of low TAWSS in the MV distal to the carina and along the lateral wall of the SB. The luminal surface exposed to low TAWSS was similar before and after virtual SB angioplasty (rest: 43% vs. 41%; hyperemia: 18% vs. 21%) and primarily due to stent-induced flow alterations. Sites of elevated OSI (>0.1) were minimal but more impacted by general vessel geometry established after MV stenting. FFR measured at a jailed SB was within the normal range despite angiographic stenosis of 54%. These findings indicate that the most commonly used percutaneous interventional strategy for a bifurcation lesion causes abnormal local hemodynamic conditions. These results may partially explain the high clinical event rates in bifurcation lesions.

    Congenital single coronary artery is commonly associated with complex congenital heart diseases and manifests in infancy or childhood. But isolated single coronary artery is a rare congenital anomaly which can present as acute coronary syndrome in adults. The aim of the work is to discuss on isolated single coronary artery in two adults presenting as acute coronary syndrome. The first case underwent coronary angiography (CAG) through right radial route, but switched over to femoral for confirmation of diagnosis and due to radial spasm. An aortic root angiogram was done to rule out presence of any other coronary ostia. It revealed a single coronary artery originating from right sinus of valsalva. After giving rise to posterior descending artery branch at crux, it continued in the atrioventricular groove to the anterior basal surface of the heart and traversed as anterior descending artery. There was no atheromatous occlusive stenosis. This is R-I type single coronary artery as per Lipton classification. In the second case, angiography was completed through right radial route. It revealed a single coronary artery arising from right aortic sinus. Anterior descending and circumflex branch were originating from proximal common trunk of the single coronary artery and supplying the left side of the heart. The right coronary artery has diffuse atheromatous disease without significant stenosis in any major branch. This is R-III C type as per Lipton classification. A coronary anomaly of both origin and course is very rare. It may be encountered in adults evaluated for atherosclerotic coronary heart disease. Knowledge and understanding of anatomical types of this congenital anomaly will reduce time, anxiety, complications during CAG and cardiac surgery. PMID:25075168

    The increasing population in older age will lead to greater numbers of them presenting with acute coronary syndromes (ACS). This has implications on global healthcare resources and necessitates better management and selection for evidenced-based therapies. The elderly are a high risk group with more significant treatment benefits than younger ACS. Nevertheless, age related inequalities in ACS care are recognised and persist. This discrepancy in care, to some extent, is explained by the higher frequency of atypical and delayed presentations in the elderly, and less diagnostic electrocardiograms at presentation, potentiating a delay in ACS diagnosis. Under estimation of mortality risk in the elderly due to limited consideration for physiological frailty, co-morbidity, cognitive/psychological impairment and physical disability, less input by cardiology specialists and lack of randomised, controlled trials data to guide management in the elderly may further confound the inequality of care. While these inequalities exist, there remains a substantial opportunity to improve age related ACS outcomes. The selection of elderly patients for specific therapies and medication regimens are unanswered. There is a growing need for randomised, controlled trial data to be more representative of the population and enroll those of advanced age with co-morbidity. A lack of reporting of adverse events, such as renal impairment post coronary angiography, in the elderly further limit risk benefit decisions. Substantial improvements in care of elderly ACS patients are required and should be advocated. Ultimately, these improvements are likely to lead to better outcomes post ACS. However, the improvement in outcome is not infinite and will be limited by non-modifiable factors of age-related risk.

    2005-01-01

    Full Text Available BACKGROUND: A relationship between Chlamydia pneumoniae infection and acute coronary syndromes has not been consistently found in published studies. It has been hypothesized that a bacteriophage-infected subset of C pneumoniae may be uniquely equipped to promote atherosclerosis and acute coronary syndromes through the expression of phage genes. METHODS: The authors performed a pilot case-control study of acute coronary events. Case and control subjects were characterized demographically and according to recognized coronary risk factors. These subjects also provided serum for the detection of antibody to the elementary bodies of C pneumoniae and antibody to the Vp1 protein coded by the phage. Bivariate and multivariate comparisons were performed using statistics appropriate for paired analyses. RESULTS: Antibodies to C pneumoniae, Vp1 protein or both were not associated with acute coronary events by bivariate or multivariate analysis. As expected, case subjects were significantly more likely to have hypertension, hypercholesterolemia or diabetes mellitus. CONCLUSION: The present study adds to a growing body of literature that does not support the hypothesized relationship between C pneumoniae (or a phage-infected subset of C pneumoniae and acute coronary syndromes.

    Early clinical trials of eptifibatide did not show a significant association between eptifibatide and the development of thrombocytopenia, thrombosis, or disseminated intravascular coagulation. However, more recent literature has suggested a significant association between eptifibatide and the development of thrombocytopenia and thrombosis. Although the true incidence and the pathophysiology of these associations are unknown, the development of these events can be life-threatening. Herein, we describe the case of a patient who experienced acute onset of profound thrombocytopenia, developing thrombosis, pulmonary emboli, and disseminated intravascular coagulation. This paper adds to the few previous reports of cases that suggested an association between thrombocytopenia, thrombosis, and the administration of eptifibatide. To the best of our knowledge, this is the first case report in the medical literature that associates the new onset of thrombocytopenia, thrombosis, and disseminated intravascular coagulation with the administration of eptifibatide. We also provide a subject review.

    2015-10-01

    When providing care for patients who are discharged from the hospital after experiencing acute coronary syndrome (ACS), several issues should be addressed. Drug regimens should be reviewed to ensure that patients are taking appropriate drugs, including antiplatelet agents, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, aldosterone antagonists, beta blockers/calcium channel blockers, cholesterol-lowering drugs, and nitroglycerin. The review also should confirm that patients understand when and how to take their drugs, and that there are no obstacles (eg, cost) that might result in nonadherence to drug regimens. Lifestyle modifications, including improvements in diet and exercise regimens, along with participation in a cardiac rehabilitation program, should be encouraged. Risk factor reduction measures include smoking cessation for smokers, weight management for patients who are overweight, and optimal control of blood pressure and blood glucose levels. Appropriate vaccinations should be administered; influenza and pneumococcal vaccines are indicated for all patients with ACS in the absence of contraindications. Patients requiring pain control should avoid use of nonsteroidal anti-inflammatory drugs because they increase the risk of cardiovascular events; acetaminophen or other drugs should be used. Finally, depression is common among patients with ACS. Screening for and management of depression are significant components of care. PMID:26439396

    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.

  3. Acute Right Coronary Ostial Stenosis during Aortic Valve Replacement

    2012-01-01

    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.

    Abstract: In this article, we outline the plans, protocols and strategies to set up the first nationwide primary Percutaneous Coronary Intervention (PCI) program for ST-elevation myocardial Infarction (STEMI) in Qatar, as well as the difficulties and the multi-disciplinary solutions that we adopted in preparation. We will also report some of the landmark literature that guided our plans. The guidelines underscore the need for adequate number of procedures to justify establishing a primary-PCI service and maintain competency. The number of both diagnostic and interventional procedures in our centre has increased substantially over the years. The number of diagnostic procedures has increased from 1470 in 2007, to 2200 in 2009 and is projected to exceed 3000 by the end of 2012. The total number of PCIs has also increased from 443 in 2007, to 646 in 2009 and 1176 in 2011 and is expected to exceed 1400 by the end of 2012. These figures qualify our centre to be classified as ‘high volume’, both for the institution and for the individual interventional operators. The initial number of expected primary PCI procedures will be in excess of 600 procedures per year. Guidelines also emphasize the door to balloon time (DBT), which should not exceed 90 minutes. This interval mainly represents in-hospital delay and reflects the efficiency of the hospital system in the rapid recognition and transfer of the STEMI patient to the catheterization laboratory for primary-PCI. Although DBT is clearly important and is in the forefront of planning for the wide primary PCI program, it is not the only important time interval. Myocardial necrosis begins before the patient arrives to the hospital and even before first medical contact, so time is of the essence. Therefore, our primary PCI program includes a nationwide awareness program for both the population and health care professionals to reduce the pre-hospital delay. We have also taken steps to improve the pre-hospital diagnosis of

    Depression is a risk factor for morbidity and mortality in patients with coronary heart disease (CHD), especially following acute coronary syndrome (ACS). Evidence from recent clinical trials suggests that treatment-resistant depression may be associated with a particularly high risk of mortality or cardiac morbidity in post-ACS patients. This manuscript reviews this evidence, and considers possible explanations for this relationship. Directions for future research are also considered, with p...

    Objective To prospectively evaluate the safety and therapeutic efficacy ofdalteparin in patients with high risk non-ST-elevation acute coronary syndromes (ACS) during percutaneous coronary intervention (PCI). Methods Atotal of 175 patients with high risk non-ST-elevation ACS were randomly assigned to 2 groups [dalteparin group and unfractionated heparin (UFH) group]. The patients in dalteparin group were given dalteparin at a dose of 5,000U subcutaneously soon after diagnosis and then an additional 60U/ kg intravenous bolus ofdalteparin before emergent PCI. Vascular access sheaths were removed immediately after PCI or coronary artery angiography; the patients in UFH group were given UFH intravenously at a dose of 25mgjust before PCI and an additional 65mg bolus was administered if angiographic findings showed that the patients were suitable for percutaneous transluminai coronary angioplasty (PTCA). Sheaths were removed at 4-6 hours after PCI; Results Eighty-three patients in dalteparin group underwent PCI while 82 patients in UFH group underwent PCI; anti-Xa activities of 52 patients in dalteparin group were measured. The average anti-Xa activity was (0.83±0.26) U/ml at 15 minutes after intravenous injection of dalteparin and anti-Xa>0.5U/ml was obtained in 96.1% of the patients; hematomas at puncture sites were significantly fewer in dalteparin group as compared with UFH group (2.3% vs 9. 2%, P < 0.05); none of the patients in 2 groups suffered major bleeding events. No death, acute arterial reocclusion or emergent revascularization events occurred at 30 days after PCI. Conclusions Our study demonstrated that early subcutaneous injection of dalteparin at a dose 5,000U after diagnosis and an additional 60U/kg intravenous bolus ofdalteparin before PCI is safe and efficacious for patients with high risk non-ST-elevation ACS undergoing emergent PCI

    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. If defibrillation is not available in patients with cardiac arrest due to VTA

    Regardless of the diabetic status of patients with coronary artery disease, hyperglycemia and hypoglycemia are adversely associated with cardiovascular events. The relationship between glucose levels and increased mortality risk in acute myocardial infarction has been shown through various glucose metrics; however, there is a dearth of multivariate analysis of the relationship between elective coronary angioplasty and preprocedural blood glucose levels.

  3. Laser angioplasty for cardiovascular disease

    Okada, Masayoshi

    2005-07-01

    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.

  4. Comparison of mortality benefit of immediate thrombolytic therapy versus delayed primary angioplasty for acute myocardial infarction.

    Kent, David M; Ruthazer, Robin; Griffith, John L; Beshansky, Joni R; Grines, Cindy L; Aversano, Thomas; Concannon, Thomas W; Zalenski, Robert J; Selker, Harry P

    Primary percutaneous coronary intervention (PPCI) yields superior mortality outcomes compared with thrombolysis in ST-elevation acute myocardial infarction (STEMI) but takes longer to administer. Previous meta-regressions have estimated that a procedure-related delay of 60 minutes would nullify the benefits of PPCI on mortality. Using a combined database from randomized clinical trials and registries (n = 2,781) and an independently developed model of mortality risk in STEMI, we developed logistic regression models predicting 30-day mortality for PPCI and thrombolysis by examining the influence of baseline risk on the treatment effect of PPCI and on the hazard of treatment delay. We used these models to solve mathematically for "time interval to mortality equivalence," defined as the PPCI-related delay that would nullify its expected mortality benefit over thrombolysis, and to explore the influence of baseline risk on this value. As baseline risk increases, the relative benefit of PPCI compared with thrombolytic therapy significantly increases (p = 0.002); patients with STEMI at relatively low risk of mortality accrue little or no incremental mortality benefit from PPCI, but high-risk patients benefit greatly. However, as baseline risk increases, the hazard associated with longer treatment-related delay also increases (p = 0.007). These 2 effects are compensatory and yield a roughly uniform time interval to mortality equivalence of approximately 100 minutes in patients who have at least a moderate degree of mortality risk (> approximately 4%). In conclusion, the mortality benefits of PPCI and the hazard of PPCI-related delay depend on baseline risk. Previous meta-regressions appear to have underestimated the PPCI-related delay that would nullify the incremental benefits of PPCI. PMID:17493465

  5. Eventos adversos e motivos de descarte relacionados ao reuso de produtos médicos hospitalares em angioplastia coronária Adverse events and reasons for discard related to the reuse of cardiac catheters in percutaneous transluminal coronary angioplasty

    the brand-new and reuse of medical equipment. METHOD: Sixty patients were studied (48.3% with unstable angina, 45% with acute myocardial infarction and 6.7% with other diagnoses. 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.

  6. Coronary microvascular obstruction in acute myocardial infarction.

    2016-04-01

    The success of a primary percutaneous intervention (PCI) in the setting of ST elevation myocardial infarction depends on the functional and structural integrity of coronary microcirculation. Coronary microvascular dysfunction and obstruction (CMVO) occurs in up to half of patients submitted to apparently successful primary PCI and is associated to a much worse outcome. The current review summarizes the complex mechanisms responsible for CMVO, including pre-existing coronary microvascular dysfunction, and highlights the current limitations in the assessment of microvascular function. More importantly, at the light of the substantial failure of trials hitherto published on the treatment of CMVO, this review proposes a novel integrated therapeutic approach, which should overcome the limitations of previous studies.

    is coronary artery bypass surgery. 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.

    Objective: To investigate the relationship of matrix metalloproteinase-9 polymorphism to acute coronary syndrome and its affect on the severity of coronary artery disease. Methods: By means of polymerase chain reaction (PCR) and restriction fragment length polymorphism, genotypes of 245 patients with acute coronary syndrome(ACS) and 205 healthy subjects were tested. Genotypes displaying C-1562T functional promoter polymorphism (of the MMP-9 gene) were determined. The relationship between the polymorphism of the MMP-9 gene and ACS and the severity of coronary vessels diseased was analyzed. Results: The frequency of C/T plus T/T genotypes and T allele in patients with ACS was significantly higher than that in healthy subjects (22.1% vs 12.7% and 11.4% vs 6.6% respectively). But they were not associated with the number of coronary arteries diseased. Conclusion:The MMP-9 polymorphism may be susceptible to ACS. But there was not significant difference between the AMI and UAP subgroups.

    Full Text Available Asli Tanindi, Mustafa CemriGazi University Faculty of Medicine, Department of Cardiology, Ankara, TurkeyAbstract: Acute coronary syndromes comprise a large spectrum of clinical conditions ranging from unstable angina pectoris to acute ST-elevation myocardial infarction. Chest pain is usually the major symptom of atherosclerotic heart disease; however, it may be challenging to diagnose correctly, especially in the emergency department, because of the ambiguous way that pain is characterized by some patients. Cardiac troponins are sensitive and specific biomarkers used in the diagnosis of myocardial infarction that are released into the bloodstream when cardiac myocytes are damaged by acute ischemia or any other mechanism. They are the cornerstone for the diagnosis, risk assessment, prognosis, and determination of antithrombotic and revascularization strategies. However, troponin elevation indicates the presence, not the mechanism, of myocardial injury. There are many clinical conditions other than myocardial infarction that cause troponin elevation; thus, the physician should be aware of the wide spectrum of disease states that may result in troponin elevation and have a clear understanding of the related pathophysiology to effectively make a differential diagnosis. This review focuses on causes of troponin elevation other than acute coronary syndromes.Keywords: cardiac troponin, troponin elevation without acute coronary syndrome, differential diagnosis

    Objective: To assess the value of stress-rest 99Tcm-MIBI (ST-RE) SPECT imaging for evaluation of perfusion improvement, prediction of restenosis (RS) and cardiac event rate in patients after percutaneous transluminal coronary angioplasty (PTCA). Methods: 99Tcm-MIBI ST-RE SPECT imaging was performed on 100 patients [(52 +- 9) years old] (14 +- 15) months after PTCA. On 30 of the 100 patients, ST-RE SPECT imaging were also performed before PTCA, and 30 patients underwent coronary angiography (CAG). The perfusion findings of myocardial segments were qualitatively classified into four patterns: normal (N), reversible defect (RD), partial reversible defect (PRD) and fixed defect (FD). Restenosis was predicted on the basis of RD or PRD. During the follow-up, cardiac death, myocardial infarction (MI), unstable angina and revascularization were considered as cardiac events. Results: 1) Among 100 patients, RD or PRD was observed in 28 patients, indicating myocardial ischemia (IS); FD was observed in 20 patients, indicating MI. The rate of occurrence of ischemic segments had no significant difference between patients with or without MI(P>0.05). 2) Among 30 patients, perfusion imaging was improved in 23 patients, the improved rate was 76.7%. The number of ischemic segments was decreased from 100 (37%) before PTCA to 10 (3.7%) after PTCA (P99Tcm-MIBI SPECT is a useful noninvasive method for evaluating the effect of PTCA and for predicting RS, and it is of high value for predicting cardiac events

    The 12-lead electrocardiogram(ECG)is a crucial tool in the diagnosis and risk stratification of acute coronary syndrome(ACS).Unlike other 11 leads,lead aVR has been long neglected until recent years.However,recent investigations have shown that an analysis of ST-segment shift in lead aVR provides useful information on the coronary angiographic anatomy and risk stratification in ACS.ST-segment elevation in lead aVR can be caused by(1)transmural ischemia in the basal part of the interventricular septum caused by impaired coronary blood flow of the first major branch originating from the left anterior descending coronary artery;(2)transmural ischemia in the right ventricular outflow tract caused by impaired coronary blood flow of the large conal branch originating from the right coronary artery;and(3)reciprocal changes opposite to ischemic or non-ischemic ST-segment depression in the lateral limb and precordial leads.On the other hand,ST-segment depression in lead aVR can be caused by transmural ischemia in the inferolateral and apical regions.It has been recently shown that an analysis of T wave in lead aVR also provides useful prognostic information in the general population and patients with prior myocardial infarction.Cardiologists should pay more attention to the tracing of lead aVR when interpreting the12-lead ECG in clinical practice.

    Full Text Available A number of "interesting" risk markers have been proposed as providing prognostic information in acute coronary syndromes (ACS. Elevation in plasma inflammatory and necrosis biomarkers have been related to future cardiovascular events in individuals with or without prior myocardial infarction. Recently BNP and pro-BNP are entered in clinical practice to recognize patients at major risk, providing incremental information respect to the traditional markers. Together with these laboratory indexes, a few of promising laboratory markers once easily available, could become useful in identification of patients at high risk. Several studies evaluated many markers of platelet aggregation, endothelial dysfunction and vascular thrombosis, but it is not yet clear whether each of the proposed markers may provide incremental predictive information. We describe, following the most studies reported in literature, the laboratory markers with potential clinical and prognostic power that could early help physicians in the identifi cation of patients with impaired coronary disease and more narrowed coronary arteries.

    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.

    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.

Therefore, the evaluation of risk is an essential step in the management of such patients. We report two cases – a 86-year-old male, and a 46-year-old one – with acute coronary syndrome with non-ST-segment elevation, showing the importance of risk assessment to determine management strategy. Two risk profile scores were used: TIMI score and GRACE score. Routine use of validated risk score may facilitate more appropriate tailoring of intensive therapies, but the clinical reasoning of the physician is essential to take right decisions.

    Full Text Available Nicholas B Norgard,1 Mazen Abu-Fadel21University at Buffalo, School of Pharmacy and Pharmaceutical Sciences, Buffalo, NY, USA; 2University of Oklahoma Health Sciences Center, Cardiovascular Section, Oklahoma City, OK, USAAbstract: Antiplatelet agents are the cornerstone of treatment for patients with acute coronary syndrome (ACS undergoing percutaneous coronary intervention (PCI. Clopidogrel, when added to aspirin, has demonstrated considerable success at reducing thrombotic complications of ACS and/or PCI compared to aspirin alone and is standard of care for the management of patients with ACS and in patients undergoing PCI. Prasugrel is a novel thienopyridine antiplatelet agent recently approved for the treatment of patients with ACS undergoing PCI. Prasugrel provides greater and more consistent platelet inhibition than clopidogrel due to earlier and more extensive formation of its active metabolite. The enhanced platelet inhibition with prasugrel led to a reduction in major adverse cardiovascular events in patients with moderate to high risk ACS scheduled for PCI in the phase 3 TRITON-TIMI 38 trial. This benefit was seen more in patients suffering a STEMI and those with diabetes. However, this reduction in events was met with a significant increase in the risk of bleeding which overcame prasugrel’s benefit in certain groups. Future studies with prasugrel are needed to determine its optimal utilization to minimize bleeding risks and evaluate its outcomes in ACS and safety profile in special patient populations.Keywords: clopidogrel, prasugrel, percutaneous coronary intervention, acute coronary syndrome

    2015-12-01

    The feasibility and safety of transradial coronary intervention was demonstrated soon after the description of the transfemoral approach, despite which the use of the femoral artery still dominates in acute coronary syndrome intervention. The advantages of using the radial artery are virtual elimination of access site complications and an important reduction in bleeding, both of which are of utmost importance to the patient with myocardial infarction. Randomised controlled trials have now documented what seems inherent; that transradial intervention should bring with it an advantage in terms of morbidity and mortality in this cohort. The potential disadvantages in terms of speed of procedure and radiation exposure are negated by operator experience. Registries have illustrated that conversion on a large scale from the femoral to the transradial approach is safe and saves lives, most convincingly so in acute coronary syndrome intervention. This review discusses the potential benefits and risks of the alternative access sites in acute patients and explores how these are borne out in the published data.

    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.

    Full Text Available Trastuzumab is a monoclonal antibody highly effective in the treatment of several cancers, but its use is associated with cardiac toxicity which usually responds to cessation of the drug and/or medical therapy. We present an unusual case of acute cardiac toxicity temporally related to administration of trastuzumab in which the clinical presentation suggested an acute coronary syndrome. Coronary angiography, however, demonstrated minimal epicardial disease, but new wall motion abnormalities. Furthermore, the patient did not respond to withdrawal of the drug or medical therapy for heart failure.

    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.

    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.

    The occurrence of an acute myocardial infarction (MI) following a scorpion sting has been very rarely reported in the previous literature. Possible pathogenetic mechanisms include severe hypotension due to hypovolaemic shock and coronary spasm with subsequent thrombosis of coronary vessels developed after the release of vasoactive, inflammatory and thrombogenic substances contained in the scorpion venom. All of the previously reported cases had normal coronary angiogram. We report a case of a 65-year-old woman who presented with severe scorpion sting and was treated with prazosin. But a few hours later, she developed acute anterior wall MI. Coronary angiogram revealed the presence of significant stenosis in coronary arteries. As acute MI owing to significant coronary artery disease can be evident after severe scorpion envenomation, so every case of acute coronary syndrome following scorpion sting needs early diagnosis, thorough cardiovascular evaluation and appropriate treatment.

    Full Text Available Traumatic coronary artery dissection is an uncommon cause of acute myocardial infarction (AMI. We report a case of blunt chest trauma resulting from a motorcycle collision causing ostial dissection of the left anterior descending (LAD artery in a 31-year-old previously healthy male. The patient also suffered from compound comminuted fractures of the humerus and ulna and severe liver laceration, which hampered both percutaneous and surgical acute revasularization. After a stormy hospital course, a bare metal stent was implanted to seal the LAD artery dissection. The patient was discharged in a stable condition and was followed-up for rehabilitation. This case report underscores the multidisciplinary approach in facing challenges encountered after rare sequelae of chest trauma.

    Ischemic mitral regurgitation (IMR) is a common complication of acute myocardial infarction (AMI). Current evidences suggest that revascularization of the culprit vessels with percutaneous coronary artery intervention (PCI) or coronary artery bypass grafting can be beneficial for relieving IMR. A 2.5-year follow-up data of a 61-year-old male patient with ST-segment elevation AMI complicated with IMR showed that mitral regurgitation area increased five days after PCI, and decreased to lower steady level three months after PCI. This finding suggest that three months after PCI might be a suitable time point for evaluating the possibility of IMR recovery and the necessity of surgical intervention of the mitral valve for AMI patient.

    Hookah (water pipe) smoking is a major new understudied epidemic affecting youth. Because burning charcoal is used to heat the tobacco product, hookah smoke delivers not only nicotine but also large amounts of charcoal combustion products, including carbon-rich nanoparticles that constitute putative coronary vasoconstrictor stimuli and carbon monoxide, a known coronary vasodilator. We used myocardial contrast echocardiography perfusion imaging with intravenous lipid shelled microbubbles in young adult hookah smokers to determine the net effect of smoking hookah on myocardial blood flow. In 9 hookah smokers (age 27 ± 5 years, mean ± SD), we measured myocardial blood flow velocity (β), myocardial blood volume (A), myocardial blood flow (A × β) as well as myocardial oxygen consumption (MVO2) before and immediately after 30 minutes of ad lib hookah smoking. Myocardial blood flow did not decrease with hookah smoking but rather increased acutely (88 ± 10 to 120 ± 19 a.u./s, mean ± SE, p = 0.02), matching a mild increase in MVO2 (6.5 ± 0.3 to 7.6 ± 0.4 ml·minute(-1), p hookah, the increased MVO2 was accompanied by decreased heart rate variability, an indirect index of adrenergic overactivity, and eliminated by β-adrenergic blockade (i.v. propranolol). In conclusion, nanoparticle-enriched hookah smoke either is not an acute coronary vasoconstrictor stimulus or its vasoconstrictor effect is too weak to overcome the physiologic dilation of coronary microvessels matching mild cardiac β-adrenergic stimulation.

    Acute coronary syndromes have a wide spectrum of clinical presentations and risk of adverse outcomes. A distinction should be made between treatable (extent of ischemia, severity of coronary disease and acute hemodynamic deterioration) and untreatable risk (advanced age, prior myocardial damage, chronic kidney dysfunction, other comorbidities). Most of the patients with "untreatable" risk have been excluded from the "guideline-generating" clinical trials. In recent years, despite the paucity of specific randomized trials, major advances have been completed in the management of elderly patients and patients with comorbidities: from therapeutic nihilism to careful titration of antithrombotic agents, a shift toward the radial approach to percutaneous coronary interventions, and also to less-invasive cardiac surgery. Further advances should be expected from the development of drug regimens suitable for use in the elderly and in patients with renal dysfunction, from a systematic multidisciplinary approach to the management of patents with diabetes mellitus and anemia, and from the courage to undertake randomized trials involving these high-risk populations.

    Objective: To explore the relationship of Traditional Chinese Medicine (TCM) Syndrome type and coronary arteriography (CAG) with respect to the number and degree of stenosed branches of coronary artery (CA) and ACC/AHA stage of acute coronary syndrome (ACS), to provide an objective evidence for TCM Syndrome typing on ACS.Methods: Ninety patients of ACS with their TCM Syndrome typing and CAG successfully conducted were enrolled in this study. They were classified into 3 Syndrome types, the blood stasis type (typeⅠ), the phlegm stagnant with blood stasis type (typeⅡ), and the endogenous collateral Wind type (typeⅢ). The scores of the number and severity of the stenosis branch of CA and ACC/AHA lesion stage in different Syndrome types were calculated respectively and analysed statistically by Ridit analysis.Results: The number of stenosed branches increased gradually with the Syndrome type changing from Ⅰ→Ⅱ→Ⅲ, compared the type Ⅲ with the other two types(P<0.01). The severity of stenosis in typeⅠ and Ⅱ were similar, but that of Type Ⅲ, much aggravated was significantly different from that in the former two (P<0.01). The ACC/AHA stage of coronary lesion tended to be more complex as the Syndrome type changed, patients of TCM typeⅠ and Ⅱ had mostly lesion of stage A or B1 , while lesion in majority of patients of type Ⅲ belonged to stage B2 or C, comparison between the three types showed significant difference (P<0.01). Conclusion: Most ACS patients of TCM Syndrome type Ⅲ with tri-branch, severe stenosed coronary arteries, belong to the complex ACC/AHA stage of B2 and C.

    The medical management of acute coronary syndrome (ACS) follows the recommendations of international medical societies. The call to the emergency services by the patient triggers a race against the clock in pre-hospital care. It is essential to reduce the duration of the inadequate perfusion of the heart in order to limit its consequences. An effective reperfusion strategy must be planned in advance taking into account the logistical constraints. It is crucial that the general public is educated to recognise the signs of ACS and to call the emergency services immediately (such as 15, 112 or 991). PMID:26040140

    We evaluated the effects of myocardial perfusion after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) on gender-based mortality rates. Research has demonstrated a gender-specific response of cardiomyocytes to ischemia and a potential increase in myocardial salvage in women compared with men. Myocardial blush grade (MBG), an angiographic surrogate of myocardial perfusion, is an independent predictor of early and late survival after AMI. Whether the incidence and prognosis of myocardial perfusion differs according to gender among patients with AMI undergoing PCI is unknown. MBG and short- and long-term mortality were evaluated in 1,301 patients (male = 935; female = 366) with AMI randomized to primary angioplasty ± abciximab versus stent ± abciximab. Following PCI, >96% of patients achieved final Thrombolysis In Myocardial Infarction 3 flow, of which MBG 2/3 was present in 58.3% of women versus 51.1% of men (p = 0.02). Worse MBG was an independent predictor of mortality in women at 30 days (7.4% for MBG 0/1 vs 2.4% for MBG 2/3, p = 0.04) and at 1-year (11.0% for MBG 0/1 vs 3.4% for MBG 2/3, p = 0.01); however, MBG was not associated with differences in mortality for men. In conclusion, impaired myocardial perfusion following PCI for AMI, indicated by worse MBG, is an independent predictor of early and late mortality in women but not in men. These findings imply an enhanced survival benefit from restoring myocardial perfusion for women compared with men during primary angioplasty and may have clinical implications for interventional strategies in women.

  20. Noninvasive imaging in acute coronary disease. A clinical perspective

    International Nuclear Information System (INIS)

    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

    Aortic valve perforation is an extremely rare complication after percutaneous coronary intervention. The case is presented of a 49-year-old male with aortic valve regurgitation secondary to the intra-aortic protrusion of a right coronary stent. The patient had undergone an apparently successful rescue percutaneous transluminal coronary angioplasty with a drug-eluting stent following failed fibrinolysis, but one month later was readmitted for acute pulmonary edema. Further investigations demonstrated new-onset aortic regurgitation. Medical stabilization was achieved and an elective aortic valve replacement and coronary revascularization performed. Intraoperatively, the stent was found to be partially deployed within the aortic lumen, causing perforation to the non-coronary cusp.

    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). Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67%) patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Full Text Available Coronary heart disease and acute coronary syndrome (ACS are a significant cause of morbidity and mortality all over the world. Antiplatelet agents play an essential role in the treatment of acute coronary syndrome (ACS, usually with aspirin and a thienopyridine. Currently, clopidogrel, a second generation thienopyridine, is the main drug of choice, and the combination of aspirin and clopidogrel is administered orally for the treatment of ACS. Clopidogrel, the most commonly used thienopyridine, is limited by a high degree of interpatient variability and inconsistent inhibition of platelets. Ticagrelor, a new, oral, direct-acting P2Y12 receptor antagonist, produces a more profound and consistent antiplatelet effect than clopidogrel. The U.S. Food and Drug Administration approved Ticagrelor on July 20, 2011. Furthermore, ticagrelor has at least one active metabolite, which has pharmacokinetics that are very similar to the parent compound. Therefore, ticagrelor has a more rapid onset and more pronounced platelet inhibition than other antiplatelet agents. The safety and efficacy of ticagrelor compared with clopidogrel, in an ACS patient, has been recently evaluated by the PLATelet inhibition and patient Outcomes (PLATO trial. Clinical studies of patients with both ST-elevation and non-ST-elevation ACS have shown that ticagrelor, when compared with clopidogrel, reduces the rates of vascular death and myocardial infarction. The clinical data currently available indicate that ticagrelor is a promising option for the treatment of patients with ACS and may be of particular use in those at high risk for ischemic events or in those unresponsive to clopidogrel.

    Background 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.Methods 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.Results 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 (△eGFR)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, △eGFR in benazepril group was slightly lower than that in the control group, but the difference was not statistically significant.Conclusions Benazepril has a protective effect on mild to moderate impairment of renal function during

    Background: Coronary artery disease is the main cause of death in Brazil. In the Brazilian public health system, the in-hospital mortality associated with acute myocardial infarction is high. The Minas Telecardio 2 Project (Projeto Minas Telecardio 2) aims at implementing a myocardial infarction system of care in the Northern Region of Minas Gerais (MG) to decrease hospital morbidity and mortality. The aim of this study was to describe the profile of the patients with acute coronary syndrome (ACS) cared for in the period that preceded the implementation of the system of care. Methods: Observational, prospective study of patients with ACS admitted between June 2013 and March 2014 to six emergency departments in Montes Claros, MG, and followed up until hospital discharge. Results: During the study period, 593 patients were admitted with a diagnosis of ACS (mean age 63 ± 12 years, 67.6% men), including 306 (51.6%) cases of unstable angina, 214 (36.0%) of ST-elevation myocardial infarction (STEMI), and 73 (12.3%) of non-ST-elevation myocardial infarction (NSTEMI). The total STEMI mortality was 21%, and the in-hospital mortality was 17.2%. In the STEMI patients, 46,0% underwent reperfusion therapy, including primary angioplasty in 88 and thrombolysis in six. Overall, aspirin was administered to 95.1% of the patients within 24 hours and to 93.5% at discharge, a P2Y12 inhibitor was administered to 88.7% participants within 24 hours and to 75.1% at discharge. A total of 73.1% patients received heparin within 24 hours. Conclusion: We observed a low reperfusion rate in patients with STEMI and limited adherence to the recommended ACS treatment in the Northern Region of MG. These observations enable opportunities to improve health care. PMID:27355471

    Objective: To determine to what extent evidence based guidelines are followed in the management of acute coronary syndromes (ACS) in the UK, elsewhere in Europe, and multinationally, and what the outcomes are. Design: Multinational, prospective, observational registry (GRACE, global registry of acute coronary events) with six months’ follow up. Setting: Patients presenting to a cluster of hospitals. The study was designed to collect data representative of the full spectrum of ACS in specific geographic populations. Patients: Patients admitted with a working diagnosis of unstable angina or suspected myocardial infarction (MI). Main outcome measures: Death during hospitalisation and at six months’ follow up (adjusted for baseline risks). Results: In ST elevation MI, reperfusion was applied more often in the UK (71%) than in Europe (65%) and multinationally (59%) (p < 0.01). However, this was almost entirely by lytic treatment, in contrast with elsewhere (primary percutaneous coronary intervention 1%, 29%, 16%, respectively). Statins were applied more frequently in the UK for all classes of patients with ACS (p < 0.0001). In contrast there was lower use of revascularisation procedures in non-ST MI (20% v 37% v 28%, respectively) and glycoprotein IIb/IIIa antagonists (6% v 25% v 26%, respectively). In-hospital death rates, adjusted for baseline risk, were not significantly different but six month death rates were higher in the UK for ST elevation MI (7.2% UK, 4.3% Europe, 5.3% multinationally; p < 0.0001) and non-ST elevation MI (7.5%, 6.2%, and 6.7%, respectively; p  =  0.012, UK v Europe). Conclusions: Current management of ACS in the UK more closely follows the recommendations of the National Service Framework than British or European guidelines. Differences in practice may account for the observed higher event rates in the UK after hospital discharge. PMID:15710703

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

The aim of this study is to look at the frequency and prognostic significance of acute phase hyperglycemia among patients attending the coronary care unit with acute coronary syndrome over the in-hospital admission days.Methods: The study included 287 consecutive patients in the Al- Faiha Hospital in Basrah (Southern Iraq during a one year period from December 2007 to November 2008. Patients were divided into two groups with respect to admission plasma glucose level regardless of their diabetes status (those with admission plasma glucose of <140 mg/dl (7.8 mmol/L and those equal to or more than that. Acute phase hyperglycemia was defined as a non-fasting glucose level equal to or above 140 mg/dl (7.8 mmol/L regardless of past history of diabetes.Results: Sixty one point seven percent (177 of patients were admitted with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences were found between both groups regarding the mean age, qualification, and smoking status, but males were predominant in both groups. A family history of diabetes, and hypertension, were more frequent in patients with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences between the two groups regarding past history of ischemic heart disease, stroke, lipid profile, troponin-I levels or type of acute coronary syndrome. Again heart failure was more common in the admission acute phase hyperglycemia group, but there was no difference regarding arrhythmia, stroke, or death. Using logistic regression with heart failure as the dependent variable we found that only the admission acute phase hyperglycemia (OR=2.1344, 95�0CI=1.0282-4.4307; p=0.0419 was independently associated with heart failure.

Clopidogrel in combination with aspirin is the recommended standard of care for reducing the occurrence of cardiovascular events in patients with acute coronary syndromes undergoing percutaneous coronary intervention. However, major adverse cardiovascular events including stent thrombosis occur in patients taking clopidogrel and aspirin. A growing body of evidence demonstrates that high post-treatment platelet reactivity on antiplatelet treatment is associated with increased risk of adverse clinical events. Clopidogrel requires conversion to active metabolite by cytochrome P450 isoenzymes. The active metabolite inhibits ADP-stimulated platelet activation by irreversibly binding to P2Y12 receptors. Recently, the loss-of-function CYP2C19*2 allele has been associated with decreased metabolization of clopidogrel, poor antiaggregant effect, and increased cardiovascular events. In high risk vascular patients, the CYP2C19*2 polymorphism is a strong predictor of adverse cardiovascular events and particularly of stent thrombosis. Prospective studies evaluating if an antiplatelet treatment tailored on individual characteristics of patients, CYP2C19*2 genotypes, platelet phenotype, drug–drug interaction, as well as traditional and procedural risk factors, are now urgently needed for the identification of therapeutic strategies providing the best benefit for the single subject.Keywords: antiplatelet therapy, clopidogrel, cytochrome P450 2C19 loss-of-function polymorphism, major adverse cardiovascular events, percutaneous coronary interventions

    Full Text Available Abstract Background Adenosine stress cardiovascular magnetic resonance (CMR has been proven an effective tool in detection of reversible ischemia. Limited evidence is available regarding its accuracy in the setting of acute coronary syndromes, particularly in evaluating the significance of non-culprit vessel ischaemia. Adenosine stress CMR and recent advances in semi-quantitative image analysis may prove effective in this area. We sought to determine the diagnostic accuracy of semi-quantitative versus visual assessment of adenosine stress CMR in detecting ischemia in non-culprit territory vessels early after primary percutaneous coronary intervention (PCI for ST-segment elevation myocardial infarction (STEMI. Methods Patients were prospectively enrolled in a CMR imaging protocol with rest and adenosine stress perfusion, viability and cardiac functional assessment 3 days after successful primary-PCI for STEMI. Three short axis slices each divided into 6 segments on first pass adenosine perfusion were visually and semi-quantitatively analysed. Diagnostic accuracy of both methods was compared with non-culprit territory vessels utilising quantitative coronary angiography (QCA with significant stenosis defined as ≥70%. Results Fifty patients (age 59 ± 12 years admitted with STEMI were evaluated. All subjects tolerated the adenosine stress CMR imaging protocol with no significant complications. The cohort consisted of 41% anterior and 59% non anterior infarctions. There were a total of 100 non-culprit territory vessels, identified on QCA. The diagnostic accuracy of semi-quantitative analysis was 96% with sensitivity of 99%, specificity of 67%, positive predictive value (PPV of 97% and negative predictive value (NPV of 86%. Visual analysis had a diagnostic accuracy of 93% with sensitivity of 96%, specificity of 50%, PPV of 97% and NPV of 43%.

Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

    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.

    Objective Both abnormal coronary flow reserve (CFR) following percutaneous coronary intervention (PCI) and elevated white blood cell (WBC) count in acute myocardial infarction (AMI) are known as useful predictors for adverse outcomes. We evaluated the value of abnormal CFR for prediction of adverse outcomes in AMI patients with high baseline WBC count following primary PCI. Methods We studied 72 consecutive patients (mean age 56±12, male 55) presenting with AMI who were admitted to our institution. Analyze of CFR was performed following PCI by intra-coronary Doppler wire. All enroll patents’ baseline WBC count was obtained at admission and WBC count≥10.4×109/L. The occurrence of major adverse cardiac events (MACE) were analyzed during clinical follow up (12.7±7.1 months). According to the best cutoff value of CFR for predicting MACE, the patients were divided into 2 groups:group 1 with CFR<1.4, group 2 with CFR≥1.4. Results Baseline CK and CK-MB in group 1 were significantly higher than in group 2[(4 109±407)U/L vs. (2 685±562)U/L, P<0.05; (290.8± 26.6)ng/ml vs. (255.7±65.6)ng/ml, P<0.05 respectively]; Percent of post PCI MBG grade3 were more often in group 2 than in group 1(25.9%vs. 38.9%, P<0.05). MACE rate were significantly higher in group 1 than in group 2(40.7%vs. 27.8%, P<0.05), the mortality rate was significantly higher in group 1 than in group 2(13.0% vs. 0, P<0.05). Conclusions Abnormal CFR following PCI with high baseline WBC count in patients with AMI were associated with a higher incidence of adverse long-term clinical outcomes.

    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.

    Full Text Available Abstract Background While prior research has provided important information about readmission rates following percutaneous coronary intervention, reports regarding charges and length of stay for readmission beyond 30 days post-discharge for patients in a large cohort are limited. The objective of this study was to characterize the rehospitalization of patients with acute coronary syndrome receiving percutaneous coronary intervention in a U.S. health benefit plan. Methods This study retrospectively analyzed administrative claims data from a large US managed care plan at index hospitalization, 30-days, and 31-days to 15-months rehospitalization. A valid Diagnosis Related Group code (version 24 associated with a PCI claim (codes 00.66, 36.0X, 929.73, 929.75, 929.78–929.82, 929.84, 929.95/6, and G0290/1 was required to be included in the study. Patients were also required to have an ACS diagnosis on the day of admission or within 30 days prior to the index PCI. ACS diagnoses were classified by the International Statistical Classification of Disease 9 (ICD-9-CM codes 410.xx or 411.11. Patients with a history of transient ischemic attack or stroke were excluded from the study because of the focus only on ACS-PCI patients. A clopidogrel prescription claim was required within 60 days after hospitalization. Results Of the 6,687 ACS-PCI patients included in the study, 5,174 (77.4% were male, 5,587 (83.6% were Conclusions For ACS patients who underwent PCI, revascularization procedures represented a large portion of rehospitalizations. Revascularization procedures appear to be the most frequent, most costly, and earliest cause for rehospitalization after ACS-PCI.

    In the analysis of binary response data from many types of large studies, the data are likely to have arisen from multiple centers, resulting in a within-center correlation for the response. Such correlation, or clustering, occurs when outcomes within centers tend to be more similar to each other than to outcomes in other centers. In studies where there is also variability among centers with respect to the exposure of interest, analysis of the exposure-outcome association may be confounded, even after accounting for within-center correlations. We apply several analytic methods to compare the risk of major complications associated with two strategies, staged and combined procedures, for performing percutaneous transluminal coronary angioplasty (PTCA), a mechanical means of relieving blockage of blood vessels due to atherosclerosis. Combined procedures are used in some centers as a cost-cutting strategy. We performed a number of population-averaged and cluster-specific (conditional) analyses, which (a) make no adjustments for center effects of any kind; (b) make adjustments for the effect of center on only the response; or (c) make adjustments for both the effect of center on the response and the relationship between center and exposure. The method used for this third approach decomposes the procedure type variable into within-center and among-center components, resulting in two odds ratio estimates. The naive analysis, ignoring clusters, gave a highly significant effect of procedure type (OR = 1.6). Population average models gave marginally to very nonsignificant estimates of the OR for treatment type ranging from 1.6 to 1.2 with adjustment only for the effect of centers on response. These results depended on the assumed correlation structure. Conditional (cluster-specific) models and other methods that decomposed the treatment type variable into among- and within-center components all found no within-center effect of procedure type (OR = 1.02, consistently) and a

Kidney function was classified based on estimated glomerular filtration rate (eGFR) into stage 1: eGFR >90, stage 2: 60 to 89, and stage 3: 30 to 60 mL/min per 1.73 m(2). Gensini and SYNTAX scores were higher in stages 2 and 3 than in stage 1. Also, the number of diseased vessels, number of critical lesions (>50 and 70%), left main disease, and number of total occlusion vessels were higher in stages 2 and 3 than in stage 1. Multivariate linear regression analysis demonstrated that a decreased eGFR was an independent risk factor for SYNTAX and Gensini scores together with age and male gender.

    Full Text Available Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05. Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    Some studies of patients with acute myocardial infarction have reported that hyperglycaemia at admission may be associated with a worse outcome. This study sought to evaluate the association of blood glucose at admission with the outcome of unselected patients with acute coronary syndrome (ACS). Using the Acute Myocardial Infarction and unstable angina in Switzerland (AMIS Plus) registry, ACS patients were stratified according to their blood glucose on admission: group 1: 2.80-6.99 mmol/L, group 2: 7.00-11.09 mmol/L and group 3: > 11.10 mmol/L. Odds ratios for in-hospital mortality were calculated using logistic regression models. Of 2,786 patients, 73% were male and 21% were known to have diabetes. In-hospital mortality increased from 3% in group 1 to 7% in group 2 and to 15% in group 3. Higher glucose levels were associated with larger enzymatic infarct sizes (p<0.001) and had a weak negative correlation with angiographic or echographic left ventricular ejection fraction. High admission glycaemia in ACS patients remains a significant independent predictor of in-hospital mortality (adjusted OR 1.08; 95% confidence intervals [CI] 1.05-1.14, p<0.001) per mmol/L. The OR for in-hospital mortality was 1.04 (95% CI 0.99-1.1; p=0.140) per mmol/L for patients with diabetes but 1.21 (95% CI 112-1.30; p<0.001) per mmol/L for non-diabetic patients. In conclusion, elevated glucose level in ACS patients on admission is a significant independent predictor of in-hospital mortality and is even more important for patients who do not have known diabetes.

    Background Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China. Methods Between March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.Results During hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary Intervention (PCI) within 6 months was more common in patients with RA, P<0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P=0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA,P=0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P<0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P=0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P=0.006; and beta-blockers 176(64.0%) versus 864 (74

We assessed the association between PCI and long-term mortality in octogenarians with ACS. Methods and results: We followed 353 consecutive patients aged ≥80 years hospitalized with ACS during 2006–2007. Among them, 182 were treated with PCI, whereas 171 were not. PCI-treated patients were younger and more often male, and had less stroke and dependency in activities of daily living, but there were no significant differences in occurrence of diabetes mellitus, chronic obstructive pulmonary disease, hypertension, and uncured malignancies between the two groups. The association between PCI and all-cause mortality was assessed in the overall cohort and a 1:1 matched cohort based on propensity score (PS. In overall cohort, 5-year all-cause mortality was 46.2% and 89.5% in the PCI and non-PCI groups, respectively. Cox regression analysis in overall cohort by adjustment for ten baseline variables showed statistically significant association between PCI and reduced long-term mortality (P<0.001, hazard ratio 0.4, 95% confidence interval [CI] 0.2–0.5.

    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.

    Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences

    Full Text Available Ibrahim Shah, Shakeel O Khan, Surender Malhotra, Tim FischellBorgess Heart institute, Kalamazoo, Michigan, USAIntroduction: Acute coronary syndromes and non-Q-wave myocardial infarction are often initiated by platelet activation. Eptifibatide is a cyclic heptapeptide and is the third inhibitor of glycoprotein (Gp IIb/IIIa that has found broad acceptance after the specific antibody abciximab and the nonpeptide tirofiban entered the global market. Gp IIb/IIIa inhibitors act by inhibiting the final common pathway of platelet aggregation, and play an important role in the management of acute coronary syndromes.Aims: This review assesses the evidence for therapeutic value of eptifibatide as a Gp IIb/IIIa inhibitor in patients with acute coronary syndromes.Evidence review: Several large, randomized controlled trials show that eptifibatide as adjunctive therapy to standard care in patients with non-ST segment elevation acute coronary syndrome is associated with a significant reduction in the incidence of death or myocardial infarction. Data are limited regarding the use of eptifibatide in patients with ST segment elevation myocardial infarction. Cost-effectiveness analysis indicates that eptifibatide is associated with a favorable cost-effectiveness ratio relative to standard care. According to US cost-effectiveness analysis about 70% of the acquisition costs of eptifibatide are offset by the reduced medical resource consumption during the first year. Eptifibatide was well tolerated in most of the trials. Bleeding is the most commonly reported adverse event, with most major bleeding episodes occurring at the vascular access site. Major intracranial bleeds, stroke, or profound thrombocytopenia rarely occurred during eptifibatide treatment.Place in therapy: Eptifibatide has gained widespread acceptance as an adjunct to standard anticoagulation therapy in patients with acute coronary syndromes, and may be particularly useful in the management of patients

    Hyperglycemia is a frequent condition in patients with acute coronary syndromes (ACS). Hyperglycemia during ACS is caused by an inflammatory and adrenergic response to ischemic stress, when catecholamines are released and glycogenolysis induced. Although the involved pathophysiological mechanisms have not yet been fully elucidated, it is believed that hyperglycemia is associated with an increase in free fat acids (which induce cardiac arrhythmias), insulin resistance, chemical inactivation of nitric oxide and the production of oxygen reactive species (with consequent microvascular and endothelial dysfunction), a prothrombotic state, and vascular inflammation. It is also related to myocardial metabolic disorders, leading to thrombosis, extension of the damaged area, reduced collateral circulation, and ischemic preconditioning. In the last few years, several observational studies demonstrated that hyperglycemia in ACS is a powerful predictor of survival, increasing the risk of immediate and long-term complications in patients both with and without previously known diabetes mellitus. Glucose management strategies in ACS may improve outcomes in patients with hyperglycemia, perhaps by reducing inflammatory and clotting mediators, by improving endothelial function and fibrinolysis and by reducing infarct size. Recent clinical trials of insulin in ACS have resulted in varying levels of benefit, but the clinical benefit of an aggressive treatment with insulin is yet unproved.

    Ostial lesions present many challenges for percutaneous coronary intervention (PCI). Coronary anomaly will further increase difficulties in performing PCI for the patient. We present such a case as ostial occlusion of an right coronary artery with high takeoff. A 77-year-old male was referred to our institution with a diagnosis of non-ST elevated acute myocardial infarction. Selective coronary angiography and nonselective ascending aortography could not identify the origin of the right coronary artery. Multi-slices computed tomography showed RCA ostial totally occluded. A successful PCI was performed and a perfect final result was achieved utilized with many tips and tricks, including "buddy wire" technique and "focused-force" angioplasty.

    Poor prognosis is strongly associated with Acute Coronary Syndrome (ACS) and, even though a number of treatment strategies are available, the incidence of subsequent serious complications after an acute event is still high. Statins are hypolipidemic factors and recent studies have demonstrated that they have a protective role during the process of atherogenesis and that they reduce mortality caused by cardiovascular diseases. This review tries to reveal the function of the statins as a component of the primary and secondary action of acute coronary syndrome and to describe the lifestyle changes that have the same effect as the use of statins.

    Full Text Available We describe here two patients with angiographic diagnosis of intrastent restenosis and regional myocardial ischemia. One stent restenosis was located in a native coronary artery and the other in a vein graft. Both were treated with cutting balloon angioplasty (CBA, inflated at low pressures. Angiographic success was obtained and both patients were discharged in the day after the procedure. Cutting balloon angioplasty using low inflation pressures achieved important luminal gains, in these two cases of intrastent restenosis. Further studies are necessary before the effectiveness of this procedure can be precisely defined.

  5. Cross-reacting antibacterial auto-antibodies are produced within coronary atherosclerotic plaques of acute coronary syndrome patients.

    Directory of Open Access Journals (Sweden)

    Filippo Canducci

    Full Text Available Coronary atherosclerosis, the main condition predisposing to acute myocardial infarction, has an inflammatory component caused by stimuli that are yet unknown. We molecularly investigated the nature of the immune response within human coronary lesion in four coronary plaques obtained by endoluminal atherectomy from four patients. We constructed phage-display libraries containing the IgG1/kappa antibody fragments produced by B-lymphocytes present in each plaque. By immunoaffinity, we selected from these libraries a monoclonal antibody, arbitrarily named Fab7816, able to react both with coronary and carotid atherosclerotic tissue samples. We also demonstrated by confocal microscopy that this monoclonal antibody recognized human transgelin type 1, a cytoskeleton protein involved in atherogenesis, and that it co-localized with fibrocyte-like cells transgelin+, CD68+, CD45+ in human sections of coronary and carotid plaques. In vitro fibrocytes obtained by differentiating CD14+ cells isolated from peripheral blood mononuclear cells also interacted with Fab7816, thus supporting the hypothesis of a specific recognition of fibrocytes into the atherosclerotic lesions. Interestingly, the same antibody, cross-reacted with the outer membrane proteins of Proteus mirabilis and Klebsiella pneumoniae (and possibly with homologous proteins of other enterobacteriaceae present in the microbiota. From all the other three libraries, we were able to clone, by immunoaffinity selection, human monoclonal antibodies cross-reacting with bacterial outer membrane proteins and with transgelin. These findings demonstrated that in human atherosclerotic plaques a local cross-reactive immune response takes place.

    The authors report two cases of acute coronary syndrome diagnosed by diastolic color kinesis imaging (CKI), an echocardiographic technique facilitating regional left ventricular wall motion analysis. Although both patients had experienced chest pain within the previous several days, the pain had remitted prior to visiting the clinic. In addition, neither electrocardiography nor routine echocardiography revealed ischemic changes. However, diastolic CKI clearly showed regional diastolic asynchrony of the left ventricle. Coronary angiography revealed significant stenosis compatible with the region of diastolic asynchrony observed on diastolic CKI. The patients underwent successful coronary revascularization, and diastolic asynchrony disappeared after revascularization. These findings suggest that diastolic CKI is useful for the diagnosis of acute coronary syndrome, even at rest and in the absence of chest pain.

  8. Electrocardiographic localization of infarct related coronary artery in acute ST elevation myocardial infarction

    Directory of Open Access Journals (Sweden)

    C.S. Thejanandan Reddy

    2013-07-01

    Full Text Available The electrocardiogram (ECG remains a crucial tool in the identification and management of acute myocardial infarction (MI. A detailed analysis of patterns of ST-segment elevation may influence decisions regarding the use of reperfusion therapy. The early and accurate identification of the infarct-related artery on the ECG can help predict the amount of myocardium at risk and guide decisions regarding the urgency of revascularization. The specificity of the ECG in acute MI is limited by individual variations in coronary anatomy as well as by the presence of preexisting coronary artery disease, particularly in patients with a previous MI, collateral circulation, or previous coronary-artery bypass surgery. The ECG is also limited by its inadequate representation of the posterior, lateral, and apical walls of the left ventricle. Despite these limitations, the electrocardiogram can help in identifying proximal occlusion of the coronary arteries, which results in the most extensive and most severe myocardial infarctions.

    Coronary artery injury such as acute coronary dissection is an uncommon and potentially life-threatening complication after blunt chest trauma. The authors report an unusual autopsy case of a 43-year-old healthy man who suddenly collapsed after receiving a punch to the chest during the practice of kung fu. The occurrence of the punch was supported by the presence of one recent contusion on the left lateral chest area at the external examination and by areas of hemorrhage next to the left lateral intercostal spaces at the internal examination. The histological examination revealed the presence of an acute dissection of the proximal segment of the left anterior descending coronary artery. Only few cases of coronary artery dissection have been reported due to trauma during sports activities such as rugby and soccer games, but never during the practice of martial arts, sports usually considered as safe and responsible for only minor trauma.

    Full Text Available David H FitchettDivision of Cardiology, Department of Medicine, St Michael's Hospital, University of Toronto, Toronto, Ontario, CanadaAbstract: Patients with acute coronary syndrome (ACS continue to be at risk for recurrent ischemic events, despite an early invasive strategy and the use of dual antiplatelet therapy. The anticoagulant pathway remains activated for a prolonged period after ACS and, consequently, has been a target for treatment. Early studies with warfarin indicated its benefit, but the risk of bleeding and the complexities of warfarin anticoagulation resulted in little use of this strategy. Rivaroxaban, apixaban, and dabigatran are new specific inhibitors of anticoagulant factors (Xa or IIa currently available for the prevention of thrombosis and/or thromboembolism. Thus far, studies with dabigatran and apixaban in ACS have shown no clinical benefit and bleeding has been increased. The ATLAS ACS 2-TIMI 51 trial observed the impact of rivaroxaban 2.5 mg and 5 mg twice daily in patients with recent ACS receiving current management (both early invasive strategy and dual antiplatelet therapy with aspirin and clopidogrel over a follow-up period of over 1 year. Rivaroxaban 2.5 mg twice daily reduced cardiovascular death, myocardial infarction, or stroke by 16%, and both cardiovascular and all-cause mortality by approximately 20%. Although major bleeding increased from 0.6% to 2.1% and intracranial hemorrhage from 0.2% to 0.6%, there was no increase in fatal bleeding. The role of rivaroxaban in the management of ACS is discussed in this review. The reduction in mortality is the main finding that could lead to the use of rivaroxaban in the management of ACS in high-risk individuals with a low bleeding risk.Keywords: cardiovascular death, myocardial infarction, stroke, anticoagulation, bleeding risk

    2015-05-13

    We report a case of a patient admitted with an acute ST elevation myocardial infarction following occlusion of his right coronary artery, successfully treated with thrombectomy and percutaneous coronary intervention (PCI). Coronary angiography and multislice CT revealed a single right coronary artery with two anomalous branches (constituting the left coronary system); one branch passed between the pulmonary trunk and the aorta before dividing into three separate branches, while the other anomalous branch passed anterior to the pulmonary trunk, consistent with a Yamanaka R-IIIC classification. The course of this Yamanaka R-IIIC subtype is unusual as both anomalous branches combine to form a dual origin left anterior descending artery. The course of these anomalous branches places the patient at an increased risk of future myocardial ischaemia, infarction and sudden cardiac death. As symptoms typically develop on exertion, this cohort may benefit from exercise myocardial perfusion imaging to identify high-risk patients.

Coronary angiography (CAG) was performed at 90 minuts and again at 3 to 4 weeks.Results Successful thrombolysis occurred in 60 cases,but failed in 40. The ratio of reperfusion was 60%.CAG showed there were residual thrombi in 84 patients (84%) and complete coronary occlusion in 40(40% ).Angiography at 3 to 4 weeks after thrombolysis showed the stenosis worsened in 8 patients and improved in 10.Conclusion AMI is caused by sudden coronary thrombotic occlusion and can be repeffused by using thrombolytic agent or mechanical methods. Thrombolytic agents usually can not resolve thrombi completely. So percutaneous transluminal coronary angiography (PTCA) is recommended as an important method to improve serious residual stenosis.

    Full Text Available Pheochromocytoma is a rare neuroendocrine tumor with a highly variable clinical presentation. The serious and potentially lethal cardiovascular complications of these tumors are related to the effects of secreted catecholamines. We describe a case of a 50-year-old woman urgently admitted to our hospital because of symptoms and clinical and instrumental findings consistent with an acute coronary syndrome complicated by acute heart failure. Urgent coronary angiography showed normal coronary arteries. During her hospital stay, the recurrence of episodes characterized by a sudden increase in blood pressure, cold sweating, and nausea allowed us to hypothesize a pheochromocytoma. The diagnosis was confirmed by elevated levels of urinary catecholamines and by the finding of a left adrenal mass on magnetic resonance imaging. The patient underwent left adrenalectomy. Therefore, the initial diagnosis was critically reappraised and reviewed as a cardiac manifestation of a pheochromocytoma during catecholaminergic crisis.

    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

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%.

    Full Text Available Identification of patients at increased risk of death due to acute coronary syndrome (ACS can add to risk stratification and guide the next step in the management of those patients. Altered HRV has been associated with adverse outcomes in heart disease, but this has not been established in patients with acute chest pain.This study aimed to create a non-invasive, economical and risk-free method in the clinical evaluation and diagnosis of significant CAD among patients with unstable angina.Twenty-four-hour Holter recordings of 100 patients with ACS were initiated within 24 hours of admission at the emergency department; stress ECG was done for all patients while coronary angiography was done only for patients with abnormal stress test. Time domain, frequency domain, and nonlinear HRV were examined.The mean SDNN was statistically significantly lower in patients with abnormal stress test, many time and frequency domain HRV parameters was statistically lower in patients with significant coronary arteries obstruction. HRV measured close to the ACS onset may assist in risk stratification. HRV parameters may provide additional, incremental prognostic information to established assessment guidelines and possible early intervention in those patients.

    @@It is well known that acute left main coronary artery (LMCA) occlusion is one of the most severe lesions associated with coronary artery disease. A large number of LMCA patients die suddenly at the very beginning of a heart attack. Noninvasive identification of acute LMCA occlusion is very important for patient prognosis and survival, especially to predict the need of the invasive procedure of coronary artery reconstruction. In this study, we sought to evaluate retrospectively the value of ST-segment elevation in lead aVR in predicting acute myocardial infarction (AMI) and acute LMCA obstruction.

    2016-02-01

    Percutaneous coronary interventions (PCI) were proposed in the late 1970s as an alternative to surgical coronary artery bypass grafting for the treatment of coronary artery disease. Important technological progress has been made since. Balloon angioplasty was replaced by bare metal stents, which allowed to permanently scaffold the coronary vessel avoiding acute recoil and abrupt occlusion. Thereafter, the introduction of early generation drug-eluting stents (DES) has significantly improved clinical outcomes, primarily by markedly reducing the risk of restenosis. New generation DES with thinner stent struts, novel durable or biodegradable polymer coatings, and new limus antiproliferative agents, have further improved upon the safety and efficacy profile of early generation DES. The present article aims to review the impact of technological advances on clinical outcomes in the field of PCI with coronary stents, and to provide a brief overview on clinical margins of improvement and unmet needs of available DES.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a rare syndrome affecting multiple organs. There is no sufficient evidence regarding the clinical cardiac manifestations of TTP. Nonetheless, pathologic cardiac involvement is quite frequent in acute TTP, which is predominantly manifested as myocardial necrosis due to coronary arteriolar microthrombosis. The present case report describes a 43-year-old man with long-standing remitted TTP, who suffered from a sequence of refractory thrombotic epicardial coronary events. Aggressive medical and interventional therapies, including long-term dual antiplatelets and coronary angioplasty, were finally successful in remitting the thrombotic events. During his two-year follow up, he has been asymptomatic.

    Full Text Available Inflammation in formation of atherosclerosis, and acute phase reactants in the site of inflammation have major functions. Thus, do the acute phase reactants constitute the biggest risk factor for coronary artery disease? 55 patients are included in the study. Patients with coronary artery bypass surgery are included in Group I (38 patients and patients with valve operation are included in Group II (17 patients. CABG patients are further divided into two sub-groups as on-pump and off-pump. In both groups, homocystein, high sensitivity C reactive protein, ceruloplasmin, lipoprotein A and serum amyloid A protein levels are analyzed from blood and pericardial fluid. In patients with coronary artery disease, the measured high specific C- reactive protein levels from blood and pericardial fluid are found to be significantly high compared to patients with valve operation.Homocystein levels of pericardial fluids of patients with CABG are found to be higher than patients with valve operation and it is confirmed that the situation is correlated with blood homocystein levels. Although there are lots studies expressing the relation between coronary artery disease and lipoprotein A, ceruloplasmin and serum amyloid A protein levels; no significant difference for those parameters was obtained in our study. We determined that other phase reactants are higher in patients with coronary artery disease, in accordance with the literature. We aimed to state that acute phase reactants not only increase as a result of disease, but their levels are also elevated beforehand, as an indicator of the disease.

    Atherosclerotic cardiovascular disease is an epidemic in today's world. It is one of the most common causes of hospitalization and death. Therefore, remedies to control or heal the disease are continuously sought. In addition to scientifically researched therapies, patients frequently utilize alternative medicine. However, effective and toxic doses, metabolisms, and drug interactions of the herbs and herbal nutrition supplements are largely unknown. Herein, we present two cases with acute coronary syndrome. The first case was admitted with a diagnosis of acute inferior myocardial infaction (MI) and a stent was implanted to the occluded right coronary artery (RCA). There was a 50% stenosis in his left anterior descending artery (LAD). He was admitted with a diagnosis of non-ST elevation MI (NSTEMI) 6 months later. In the coronary angiogram, there was stent restenosis in RCA, the lesion in LAD had become thrombotic and progressed to a stenosis of 90%. He was referred to surgical revascularization. The second case was admitted for acute inferior MI and a stent was implanted to the occluded circumflex artery. Two months later, he was hospitalized for NSTEMI. Progression of coronary plaques to stenosis and stent restenosis was detected and he was referred to surgical revascularization. Both patients used the product sold as Clavis Panax, which contains panax ginseng, tribulus terrestris, and oat, after their first coronary intervention. Intake of a mixture of plant extracts may have serious consequences in humans as drug interactions and side effects are unknown. PMID:22864326

    In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes in the inferior leads were present and were most likely postischemic and "reischemic." Although the culprit artery could not be identified with certainty by means of these subtle changes, they correlated well with the findings on angiography and the ECG recorded afterward. This case report demonstrates the importance of analyzing ECG and its temporal changes in conjunction with evolving symptoms. PMID:27212142

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.

    Full Text Available One of the three clinical examples of hospital thrombolysis using Russian thrombolytic agent recombinant protein comprising an amino acid sequence of staphylokinase is described. 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. There were no complications registered.

    2011-06-01

    Full Text Available Introduction and Objectives: Acute myocardial infarc-tion remains a major challenge for health systems. In the classic concept of the ischemic cascade, the earliest event is the QT interval prolongation, which was previously reported in patients with unstable angina and ST elevation myocardial infarction. There has been speculation that the normalization of this interval in patients undergoing angioplasty, is a marker of successful reperfusion, thus the objective of this research is to characterize the corrected QT interval dispersion and its association with adverse outcomes in patients with acute coronary syndromes. Method: The corrected QT interval dispersion was analyzed in patients admitted to the Hospital "Comandante Manuel Fajardo Rivero" with an acute coronary syndrome from January to December 2009. The results were analyzed to provide inferential information on the basis of the statistical assessment of the SPSS processor, version 15.0. Results: The ST-segment elevation syndrome was the clinical form that included the most patients, but prolonged dispersion prevailed in those with unclassifiable syndrome, an atypical clinical presen-tation and a wrong electrocardiogram, similar behavior to that of the patients with a non-ST segment elevation syndrome, but not in those with ST segment elevation. Mortality, cardiac reinfarction, and need for myocardial revascularization were significantly associated with prolonged dispersion of the corrected QT interval. Conclusions: The prolonged dispersion of this interval could be an independent predictor of increased cardiovascular risk.

    Objective: To evaluate the therapeutic effects of 0. 014″Choice PTTM wire in chronic total occlusion angioplasty. Methods: Balloon angioplasty was attempted in 25 arteries with chronic total occlusion,with the mean time of occlusion of 17±13 months (ranging from 2 to 84 months) and mean length of 14±6mm (ranging from 5 to 25 mm). The morphology of the lesions included bridging collaterals (4 cases), calcification (3 cases) and major side branch at the lesion (4 cases) . Choice PTTM wire was used electively in all the cases. Results: Lesion was crossed successfully in 92% (23/25) cases, without incidences of dissection of the coronary artery with subintimal entry. Balloon angioplasy and stenting (n=21) were performed with good immediate angiograghic results. Acute myocardial infarction or death occurred in none of the patients.Conclusion Successful recanalization of chronic coronary total occlusions using Choice PTTM wire can be achieved with good safety.

  19. Coronary computed tomography and triple rule out CT in patients with acute chest pain and an intermediate cardiac risk for acute coronary syndrome

    International Nuclear Information System (INIS)

    Objective: To evaluate the economic impact of integrating coronary CT angiography (cCTA) or whole chest “triple-rule-out” CTA (TRO-CTA) in the work-up of patients with acute chest pain. Materials and methods: 100 consecutive emergency department patients with acute chest pain and an intermediate cardiac risk for ACS underwent cCTA or TRO-CTA (cCTA group). Diagnostic performance, rate and length of hospitalization, hospital costs, hospital reimbursement and hospital profit were analyzed. All findings were compared to those of 100 different patients with acute chest pain that were evaluated with a standard of care (SOC) diagnostic algorithm (SOC group) that did not include cCTA. Diagnostic performance (“safety”) of both algorithms was defined as the absence of major adverse cardiac events (MACE) over a 90-day follow-up period. Results: In the cCTA group 60/100 patients were safely discharged at the same day. 19/100 patients were hospitalized due to significant coronary stenosis on cCTA, which was confirmed by invasive coronary catheterization (ICC) in 17/19 patients. Relevant non-coronary disease that led to hospitalization were found in 21 patients of the cCTA group. In the SOC group all patients were hospitalized. 87 of these hospitalized patients underwent ICC for exclusion of coronary artery stenosis. A significant coronary artery stenosis was found in only 25 of these patients. Within the cCTA group no patient suffered from MACE over the 90-day follow-up period. In the SOC group 2 patients were rehospitalized during the 90-day follow-up period due to recurrent chest pain and 1 patient because of a pseudoaneurym of the left femoral artery after ICC. The median hospital costs per patient were significantly lower in the cCTA group than in the SOC group (428.9€ vs. 1575.0€, p < 0.001). The median reimbursement of the cCTA group was less compared to the SOC group (589.8€ vs. 2412.1€, p < 0.001) and patients in the cCTA group gained less profit than

    Background This study assessed the risk of developing acute coronary syndrome requiring hospitalization in association with the use of certain antipsychotic medications in schizophrenia patients. Methods A nationwide cohort of 31,177 inpatients with schizophrenia between the ages of 18 and 65 years whose records were enrolled in the National Health Insurance Research Database in Taiwan from 2000 to 2008 and were studied after encrypting the identifications. Cases (n = 147) were patients with subsequent acute coronary syndrome requiring hospitalization after their first psychiatric admission. Based on a nested case-control design, each case was matched with 20 controls for age, sex and the year of first psychiatric admission using risk-set sampling. The effects of antipsychotic agents on the development of acute coronary syndrome were assessed using multiple conditional logistic regression and sensitivity analyses to confirm any association. Results We found that current use of aripiprazole (adjusted risk ratio [RR] = 3.68, 95% CI: 1.27–10.64, p<0.05) and chlorpromazine (adjusted RR = 2.96, 95% CI: 1.40–6.24, p<0.001) were associated with a dose-dependent increase in the risk of developing acute coronary syndrome. Although haloperidol was associated with an increased risk (adjusted RR = 2.03, 95% CI: 1.20–3.44, p<0.01), there was no clear dose-dependent relationship. These three antipsychotic agents were also associated with an increased risk in the first 30 days of use, and the risk decreased as the duration of therapy increased. Sensitivity analyses using propensity score-adjusted modeling showed that the results were similar to those of multiple regression analysis. Conclusions Patients with schizophrenia who received aripiprazole, chlorpromazine, or haloperidol could have a potentially elevated risk of developing acute coronary syndrome, particularly at the start of therapy.

    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.

    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.

    Dextrocardia is a rare congenital anomaly with a prevalence of 1 in 10,000 births. The incidence of coronary artery disease in such patients is thought to be similar to that of the general public, however, patients are seldom seen during routine clinical practice and at the cardiac catheterization laboratory. Patients with this condition and acute myocardial ischemia may pose challenges at presentation, clinical and diagnostic findings and at cardiac catheterization. In this report, a male patient presenting with acute inferior myocardial infarction and three-vessel coronary artery disease was managed successfully with emergency primary angioplasty and later elective multivessel stenting. This is the first combined primary and later multivessel stenting to be reported in a single patient with dextrocardia and situs inversus. The clinical findings, details of the procedures and literature review will be discussed.

    Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patient’s prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. Material and Methods. A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort. Demographic and anamnestic data, clinical characteristics on admission, biochemical analysis of blood parameters on admission, and left ventricular ejection fraction formed the basis of the study. A number of machine learning algorithms available within Waikato Environment for Knowledge Discovery had been evaluated and the most successful was chosen. The predictive model was subsequently validated in a different population of 931 patients (validation cohort, hospitalized during 2012. Results. The best prediction results were achieved using Alternating Decision Tree classifier, which was able to predict in-hospital mortality with 89% accuracy, and preserved good performance on validation cohort with 87% accuracy. Alternating Decision Tree classifier identified a subset of 6 attributes most relevant to mortality prediction: systolic and diastolic blood pressure, heart rate, left ventricular ejection fraction, age, and troponin value. Conclusion. Data mining approach enabled the authors to develop a model capable of predicting the in-hospital outcome following percutaneous coronary intervention. The model showed excellent sensitivity and specificity during internal validation.

    Background Many studies have examined gender related differences in the presenting symptoms, management and prognosis of patients with acute coronary syndrome (ACS). Much data are available from industrialized countries, in which ACS is a major cause of morbidity and mortality, but relatively little information has been obtained from China,where an epidemic of cardiovascular disease is starting to emerge. The purpose of this study was to assess the differences in clinical practice in a national Chinese sample.Methods A total of 12 medical teaching hospitals participated in CRACE. Data collection began in 2001 and continued until 2004, 1301 patients with ACS were enrolled into the study. We compared the clinical demographics, different therapies and outcomes in hospitals between female and male patients with ACS.Results Patients had an average age of 63.13 years (ranging from 27 to 93 years) and 318 female and 983 male subjects were enrolled. Female subjects were older than male patients (67.23 years vs 61.80 years, P<0.0001). The incidence of angina, heart failure, diabetes mellitus and hypertension in the female group was higher than in male group(73.6% vs 62.3%, P<0.0001; 8.2% vs 5.7%, P=0.031; 30.8% vs 18.6%, P<0.0001 and 66.4% vs 56.8%, P=0.001 respectively), but the incidence of smoking was less in the female group than in the male group (6.6% vs 66.2%,P<0.0001). More male patients presented with ST-segment elevation myocardial infarction (STEMI) compared with female patients (48.5% vs 39%, P=0.002). With the exception of β-blocker administration, no differences were found among medications including aspirin, ACEI, lipid lowering agents and low-molecular-weight heparin (LMWH) between female and male patients presenting with ACS in hospitals. Compared with male patients with non-ST-segment elevation(NSTE) ACS, female subjects were more prone to receive β-blockers (75.1% vs 63.4%, P=0.001). Among STEMI and NSTE-ACS patients, fewer female subjects

    US healthcare expenditure per capita far exceeds that of any other nation in the world. Indeed, over the last 15 years, the USA has distantly surpassed most countries in the developed world in total healthcare expenditures per capita with the USA now spending 17.4% of its gross domestic product (GDP) on healthcare ($7960 per capita), compared with only 8.5% of GDP in Japan ($2878 per capita), a distant second. Consequently, by current projections, the US healthcare bill will have ballooned from $2.5 trillion in 2009 to over $4.6 trillion by 2020. Such spending growth rates are unsustainable and the system would soon go broke if not corrected. The drivers of these spending growth rates in US healthcare are several and varied. Indeed, in September 2012, the Institute of Medicine reported that US healthcare squandered $750 billion in 2009 through unneeded care, Byzantine paperwork, fraud and other wasteful activities. Recently, the question was raised as to whether we have too much coronary angioplasty in the USA. In this analysis, we examine these and other various related aspects of US healthcare, make comparisons with other national healthcare delivery systems, and suggest several reengineering modalities to help fix these compellingly glaring glitches and maladies of US healthcare.

    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

    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.

    Early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) is important since the benefit from more aggressive and costly treatment strategies is proportional to the risk of adverse clinical events. In the present study we assessed whether hybrid single photon emission computed tomography (SPECT)/coronary computed tomography angiography (CCTA) technology could be an appropriate tool in stratifying patients with NSTE-ACS. SPECT/CCTA was performed in 90 consecutive patients with NSTE-ACS. The Thrombolysis in Myocardial Infarction risk score (TIMI-RS) was used to classify patients as low- or high-risk. Imaging was performed using SPECT/CCTA to identify haemodynamically significant lesions defined as >50% stenosis on CCTA with a reversible perfusion defect on SPECT in the corresponding territory. CCTA demonstrated at least one lesion with >50% stenosis in 35 of 40 high-risk patients (87%) as compared to 14 of 50 low-risk patients (35%; TIMI-RS <3; p <0.0001). Of the 40 high-risk and 50 (16%) low-risk TIMI-RS patients, 16 (40%) and 8 (16%), respectively, had haemodynamically significant lesions (p = 0.01). Patients defined as high-risk by a high TIMI-RS, a positive CCTA scan or both (n = 45) resulted in a sensitivity of 95%, specificity of 49%, PPV of 35% and NPV of 97% for having haemodynamically significant coronary lesions. Those with normal perfusion were spared revascularization procedures, regardless of their TIMI-RS. Noninvasive assessment of coronary artery disease by SPECT/CCTA may play an important role in risk stratification of patients with NSTE-ACS by better identifying the subgroup requiring intervention.

    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.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. 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, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over 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. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. PMID:27232927

    This study aimed to assess if proton pump inhibitors (PPIs) may reduce the effectiveness of clopidogrel, than H2 antagonist (anti-H2) in order to determine rehospitalization for acute coronary syndrome (re-ACS), target vessel revascularization (TVR) and cardiac death. This case-control study included 176 patients with ACS undergoing angioplasty (PCI) with drug-eluting stent implantation. The population was divided into two groups: PPI group (n = 121) consisting of patients receiving at discharge dual antiplatelet therapy (DAT) plus PPI and anti-H2 group (n = 55), consisting of patients receiving at discharge DAT + H2 receptor antagonist (H2RA). In a followup of 36 months the prevalence of ACS event (P = 0.014), TVR (P = 0.031) was higher in the PPI group than in the anti-H2 group; instead there was no statistically significant difference between groups for death. The variables independently associated with ACS were the diabetes, omeprazole, and esomeprazole; instead the variables independently associated with TVR were only omeprazole. Our data shows that the use of omeprazole and esomeprazole, with clopidogrel, is associated with increased risk of adverse outcomes after PCI with drug-eluting stent implantation. PMID:22792485

    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.

    Full Text Available The management of antithrombotic therapy in atrial fibrillation patients presenting with acute coronary syndrome and/or undergoing percutaneous coronary inter vention/stenting cannot be done according to a regimented common protocol, and stroke and bleeding risk stratification schema should be employed to individualize treatment options. A delicate balance is needed between the prevention of thromboembolism, against recurrent cardiac ischemia or stent thrombosis, and bleeding risk. New guidance from a consensus document of the European Society of Cardiology Working Group on Thrombosis, endorsed by the European Heart Rhythm Association and the European Association ofPercutaneous Cardiovascular Interventions on the management of Antithrombotic Therapy in Atrial Fibrillation Patients Presenting with Acute Coronary Syndrome and/or Undergoing Percutaneous Coronary Intervention/Stenting has sought to clarify some of the major issues and problems surrounding this practice, and will allow clinicians to make much more informed decisions when faced with treating such patients.

    In patients with diabetes mellitus, cardiovascular disease is the principal cause of mortality and chest pain is the most frequent symptom in patients with stable and acute coronary artery disease. However, there is little knowledge concerning the pervasiveness of uncommon presentations in diabetics. The symptomatology of acute coronary syndrome, which comprises both pain and non-pain symptoms, may be affected by traditional risk factors such as age, gender, smoking, hypertension, diabetes, and dyslipidemia. Such atypical symptoms may range from silent myocardial ischemia to a wide spectrum of non-chest pain symptoms. Worldwide, few studies have highlighted this under-investigated subject, and this aspect of ischemic heart disease has also been under-evaluated in the major clinical trials. The results of these studies are highly diverse which makes definitive conclusions regarding the spectrum of atypical presentation of acute and even stable chronic coronay artery disease difficult to confirm. This may have a significant impact on the morbidity and mortality of coronary artery disease in diabetics. In this up-to-date review we will try to analyze the most recent studies on the atypical presentations in both acute and chronic ischemic heart disease which may give some emphasis to this under-investigated topic.

    2015-03-01

    Full Text Available INTRODUCTION : Cardiovascular disease is the commonest cause of death globally. Acute myocardial infarction generally occurs when coronary blood flow decreases abruptly after thrombotic occlusion of a coronary artery causing focal or massive necrosis of cardiac muscle. The risk factor concept implies that a person with one risk factor is more likely to develop clinical atherosclerotic event and is more likely to do so earlier than a person with no risk factors. The presence of multiple risk factors further accelerates th e atherosclerosis. Hence it is important to identify the major risk factors of coronary atherosclerosis in an individual with acute myocardial infarction so that further preventive measures can be taken in the form of lifestyle modification and pharmacothe rapy. MATERIALS AND METHODOLOGY: T his is a hospital based study. This study comprises of 100 cases of acute myocardial infarction admitted in ICCU under the department of medicine and 100 normal healthy controls in the age group of 29 - 85 years. Patients wi th the evidence of acute MI were diagnosed according to WHO criteria. Blood samples collected in vacutainers were analyzed for different biochemical parameters in the clinical biochemistry laboratory. RESULTS: Common risk factors have been evaluated in our study and we found that maximum MI patients were recorded in the age group of 51 - 60 years, with respect to other risk factors history like sex, majority of patients were males (82%, Sedentary life style (44%, Mixed dietary habits (84%, Family history o f IHD (6%, Dyslipidemia and Smoking (46%, Hypertension (31%, Diabetes (37%, Obesity (18%. In our study we found that 81% of the patients of acute MI had multiple risk factors. CONCLUSION: Thus from the study we can conclude that risk factors play a ma jor role in the genesis of coronary heart disease. Modification of these factors by pharmacotherapy, diet, physical exercises and behavioral therapy can improve the

    Myocardial infarction with normal coronary arteries (MINCA) can be observed in a relevant subset of patients with MI. It can be considered a syndrome, since it includes several clinical entities with specific pathogenetic mechanisms. Its prevalence is extremely variable, accounting for 5-25% of all acute myocardial infarctions. MINCA may arise from epicardial, microvascular, or myocardial localizations. Clinical history, echocardiography, coronary angiography and left ventriculography represent the first diagnostic step; however, additional tests are often required to confirm the diagnosis. The prognosis is extremely variable, depending on the causes of MINCA. Therefore, the identification of the correct etiology of MINCA is crucial to stratify patients appropriately and, hence, select the best treatment approach. In this review article, the pathogenesis, diagnosis, prognosis and therapy of MINCA are discussed, highlighting that coronary angiography alone is not sufficient for the complete understanding of the pathogenic mechanisms.

    Full Text Available ABSTRACT OBJECTIVE : To analyze if the demographic and socioeconomic variables, as well as percutaneous coronary intervention are associated with the use of medicines for secondary prevention of acute coronary syndrome. METHODS : In this cohort study, we included 138 patients with acute coronary syndrome, aged 30 years or more and of both sexes. The data were collected at the time of hospital discharge, and after six and twelve months. The outcome of the study was the simultaneous use of medicines recommended for secondary prevention of acute coronary syndrome: platelet antiaggregant, beta-blockers, statins and angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker. The independent variables were: sex, age, education in years of attending, monthly income in tertiles and percutaneous coronary intervention. We described the prevalence of use of each group of medicines with their 95% confidence intervals, as well as the simultaneous use of the four medicines, in all analyzed periods. In the crude analysis, we verified the outcome with the independent variables for each period through the Chi-square test. The adjusted analysis was carried out using Poisson Regression. RESULTS : More than a third of patients (36.2%; 95%CI 28.2;44.3 had the four medicines prescribed at the same time, at the moment of discharge.

    2013-01-01

    Full Text Available Dual antiplatelet therapy with aspirin and a P2Y12 receptor inhibitor represents the cornerstone therapy for patients with acute coronary syndromes or undergoing percutaneous interventions, leading to a reduction of subsequent ischemic events. Variable response to clopidogrel has received close attention, and pharmacokinetic, pharmacodynamic, and pharmacogenomic factors have been identified as culprits. This led to the introduction of newer, potentially safer, and more effective antiplatelet agents (prasugrel and ticagrelor. Additionally, several point-of-care assays of platelet function have been developed in recent years to rapidly screen individuals on antiplatelet therapy. While the routine use of platelet function testing is uncertain and not currently recommended, it may be useful in instances when the degree of platelet inhibition may be uncertain such as high-risk patients undergoing percutaneous coronary intervention or when there may be a suspected pharmacodynamic interaction with other drugs. The current paper focuses on the P2Y12 receptor inhibitors and their pharmacogenetics and indications in patients with acute coronary syndromes or receiving percutaneous coronary interventions as well as the applicability of platelet function testing in this clinical context.

    Coronary vasospasm is a rare diagnosis resulting in sudden arrhythmic cardiac arrest. We report a case of a healthy,non-smoking elderly woman resuscitated from arrhythmic cardiac arrest. She had persistent spontaneous coronaxy vasospasm, leading to right ventricular myocardial injury and failure, and shock. She responded quickly to intravenous normal saline bolus infusion, but had irreversible neurological sequelae. Additionally, she had atrial fibrillation preceding ischemic ventricular fibrillation, a rare finding in coronary vasospasm-related cardiac arrest. We suggest immediate coronary angiography of patients in sudden arrhythmic cardiac arrest with acute right ventricular failure for a prompt,accurate diagnosis and appropriate management of the coronary vasospasm.

    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.

    Full Text Available Abstract. The role of immune factors in development of atherosclerotic process and anxiety-depressive disorders is of utmost importance. Serum levels of IL-6 and -10 were studied in forty-nine patients with acute coronary syndrome, as well as their interactions with psychological state of the patients. Serum concentrations of the cytokines proved to be higher in unstable angina. A correlation was confirmed between the cytokine levels and co-morbidity with affective disorders in acute ischaemic heart disease.

    Background Omeprazole, usually used in the antiplatelet therapy during percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS), has been reported to increase ischemic events in retrospective studies. However, other clinical trials gave paradoxical results. The aim of this study was to assess the effects of omeprazole on clopidogrel efficacy and clinical events.Methods All patients (n=172) received aspirin (loading dose 300 mg and maintenance dose 100 mg/d) and clopidogrel (loading dose 600 mg and maintenance dose 75 mg/d) during the therapy. They were randomized to receive omeprazole (20 mg/d) or placebo for 30 days. Residual platelet activities in the adenosine 5'-diphosphate (ADP) pathway were detected on the fifth day after PCI with thrombelastography (TEG)-mapping. The clinical events were recorded after one month.Results According to the five levels of platelet activities, the frequency distributions of the inhibition rates were significantly different (P=0.0062). However, no significant change was seen in the distribution among the highest or the lowest inhibiting levels (>95% and <30% inhibition rate). And there were no significant differences (P >0.05) in events incidence, while gastra-intesternal bleeding decreased in co-administration of omeprazole.Conclusions Omeprazole significantly blunts clopidogreal efficacy while not exacerbates ischimic events in ACS undergoing PCI. Omeprazaole even can decrease gastra-intestinal bleeding in those patients.
