    Full Text Available Abstract Background Systolic compression of a coronary artery by overlying myocardial tissue is termed myocardial bridging. Myocardial bridging usually has a benign prognosis, but some cases resulting in myocardial ischemia, infarction and sudden cardiac death have been reported. We are reporting a case of myocardial bridging which was complicated with acute myocardial infarction associated with inappropriate blood donation. Case presentation A 33 year-old-man was admitted to our emergency with acute anteroseptal myocardial infarction after a blood donation. The electrocardiography showed sinus rhythm and was consistent with an acute anteroseptal myocardial infarction. We decided to perform primary percutanous intervention (PCI. Myocardial bridging was observed in the mid segment of the left anterior descending coronary artery on coronary angiogram. PCI was canceled and medical follow up was decided. Blood transfusion was made because he had a deep anemia. A normal hemaglobin level and clinical reperfusion was achieved after ten hours by blood transfusion. At the one year follow up visit, our patient was healthy and had no cardiac complaints. Conclusions Myocardial bridging may cause acute myocardial infarction in various clinical conditions. Although the condition in this case caused profound anemia related acute myocardial infarction, its treatment and management was unusual.

    International Nuclear Information System (INIS)

    A brief review is presented of radiopharmaceuticals used for imaging acute myocardial infarction and instrumentation using the rectilinear scanner and the scintillation camera. Clinical experience indicates that myocardial imaging with /sup 99 m/Tc pyrophosphate is a useful adjunct to the electrocardiogram and serum enzyme activity in managing patients with myocardial infarction. The technique allows rapid diagnosis, accurate localization, and an estimate of the size of acute infarcts. It can also be used to document infarct extension and in association with myocardial perfusion imaging can help differentiate fresh from old myocardial infarction

    Full Text Available Coronary artery embolism is an uncommon cause of Acute Myocardial Infarction (AMI. Herein, we reported a 24-year-old male who was admitted with acute infero-posterior myocardial infarction and cerebral Transient Ischemic Attack (TIA. He had undergone mechanical Aortic Valve Replacement (AVR surgery 6 years ago. Surprisingly, the patient had decided to stop taking his medication (warfarin 20 days earlier without any medical advice. Coronary angiography revealed a thrombus located at the distal part of the left circumflex artery. Discontinuation of anticoagulant therapy in the presence of mechanical valve prosthesis, clinical evidence of coincidental TIA, and lack of atherosclerotic risk factors were highly suggestive of coronary thromboembolism as the cause of AMI. Overall, this case report emphasized the necessity of continuous education in patients with mechanical heart valves to prevent such undesired events.

    Patients with abrupt onset of chest pain, ischemic ECG abnormalities and elevated levels of cardiac markers could be given a diagnosis of acute myocardial infarction. However, some other diseases should be taken into consideration in this clinical setting when coronary arteries are proven to be normal. Here we report a case of acute myopericarditis with clinical presentation of myocardial infarction and normal coronary anatomy. The Herpes Simplex Virus Ⅱ was considered as the organism causing myopericarditis and the patient was recovered by the treatment with valacicloavir. A precise diagnosis is a prerequisite of successful treatment and favorable prognosis.

    Primary coronary revascularization by means of percutaneous coronary intervention ( PCI) is a highly ef-fective treatment of acute myocardial infarction re-establishing coronary perfusion and stopping the ongoing necrosis in the dependent myocardium .Single-photon emission computed tomography ( SPECT) is the most widely used mo-dality assessing myocardial salvage as the difference between the acute perfusion defect before intervention and the remaining scar size measured in a second scan several days after the event .SPECT allows quantification of area at risk( AAR) and final infarct size ( FIS) by tracer injection prior to revascularization and after 1 month, respective-ly.SPECT provides the most validated measure of myocardial salvage and has been utilized in multiple randomized clinical trials.However, SPECT is logistically challenging , expensive, and includes radiation exposure .More re-cently, a large number of studies have suggested that cardiac magnetic resonance ( CMR) can determine salvage in a single examination by combining measures of myocardial oedema in the AAR exposed to ischaemia reperfusion with FIS quantification by late gadolinium enhancement .

    Inflammatory processes after myocardial infarction have gained major interest in recent cardiovascular research. It is believed that not only the degree of cell recruitment to the heart plays a pivotal role in the quality of wound healing after myocardial infarction, but also the balance between different types or even subtypes of cells. It is also this balance which is thought to control key processes in tissue repair, such as apoptosis and neoangiogenesis. In this paper, we aim to review imaging strategies (with a special focus on nuclear molecular imaging strategies) that target cells and processes involved in postischemic inflammation and that have a high potential to be translated into clinic or that are already being used and evaluated in humans.

    A 24-year-old male patient with anterior myocardial infarction, caused by embolization from mitral valve prosthesis due to inadequate anticoagulation is presented. The patient underwent cardiac catheterization within 90 minutes of arrival. Angiography showed total occlusion of the left anterior descending coronary artery (LAD) after the second diagonal branch. Thrombus was extracted with export catheter from LAD, and coronary artery perfusion was restored. The pain disappeared completely immediately after this intervention. Transoesophageal echocardiography performed 2 days later revealed no thrombus at the prosthetic valve. In conclusion, this case demonstrated that coronary embolism may occur even without prosthetic valve thrombus or dysfunction with suboptimal International Normalized Ratio levels, and can be successfully treated with coronary angiography with clot extraction with aspiration catheter (Export XT 6F Medtronic) only, without stenting.

    Full Text Available Suspected acute myocardial infarction is one of the leading causes of admission to emergency departments. In the last decade, biomarkers revolutionized the management of patients with suspected acute coronary syndromes. Besides their pivotal assistance in timely diagnosis, biomarkers provide additional information for risk stratification. Cardiac troponins I and T are the most sensitive and specific markers of acute myocardial injury. Nonetheless, in order to overcome the remaining limitations of these markers, novel candidate biomarkers sensitive to early stage of disease are being extensively investigated. Among them, copeptin, a stable peptide derived from the precursor of vasopressin, emerged as a promising biomarker for the evaluation of suspected acute myocardial infarction. In this review, we summarize the currently available evidence for the usefulness of copeptin in the diagnosis and risk stratification of patients with suspected acute myocardial infarction in comparison with routine biomarkers.

    1987-10-24

    Fibrinolysis has opened up a new avenue in the treatment of acute myocardial infarction (AMI). In principle, the rate of reperfusion depends on the type of compound used, the mode of administration and the time between onset of symptoms and the beginning of treatment. With intracoronary streptokinase the reperfusion rate is of the order of 85%. Intravenous urokinase administered as a bolus results in a reopening rate of 50-60%; a similar rate of reperfusion is achieved with rt-PA as infusion, while i.v. streptokinase produces about 50% reopened coronary vessels. The final infarct size is decreased in 70% of patients if fibrinolysis is initiated within 2.5 hours after the onset of symptoms and followed by reopening of the occluded vessel. This results in a lowering of in-hospital mortality, which in various studies is of the order of 45-60%.- Bearing in mind the contraindications, fibrinolysis should be initiated within 3 hours. Hemodynamic improvement by a decrease of infarct size may also be achieved beyond 3 hours in large anterior myocardial infarctions and in posterior infarctions with cardiogenic shock. Early initiation of thrombolysis is of major importance in improving left ventricular function and lowering mortality following acute myocardial infarction. Therefore, prehospital thrombolytic therapy should be considered. - In the postinfarction phase coronary angiography is indicated in patients with angina at rest, stable angina of ECG signs of ischemia. In this situation transfer to a specialized cardiology division for possible percutaneous transluminal angioplasty is indicated. - Reocclusion after successful thrombolysis occurs in 20-30%, and it is therefore important to avoid reinfarction to improve the long term prognosis after AMI.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3321420

    Full Text Available Abstract Introduction Spontaneous coronary artery dissection is an important yet rare cause of acute coronary syndrome. The available literature shows a higher risk factor for women, notably during pregnancy and puerperium. The incidence in postmenopausal women is exceedingly rare, and is more commonly seen in association with concurrent predisposing factors. We illustrate an extremely rare case of a 62-year-old post-menopausal woman presenting with an acute myocardial infarction secondary to spontaneous dissection of the left anterior descending artery. Subsequent investigations did not reveal the presence of any co-morbidities. To the best of our knowledge, our patient is one of the oldest documented cases of spontaneous coronary artery dissection on record, and is notable for having no known underlying risk factors for development of spontaneous coronary artery dissection. Given the paucity of literature on spontaneous coronary artery dissection, particularly in postmenopausal women, we believe this case will provide further insight into the clinical presentation and management of this rare entity. Case presentation A 62-year-old previously healthy postmenopausal Hispanic woman presented with chest pain and was found to have an ST elevation myocardial infarction. Cardiac catheterization revealed a dissection in her left anterior descending artery. Revascularization was deferred; our patient received appropriate medical management and remained asymptomatic. A full panel of tests was done to exclude underlying connective tissue disorders and vasculitis. On subsequent follow-up, our patient continued to do well and all work-up was reported as negative. Conclusion We describe the varied presentation and subsequent management of a case of spontaneous coronary artery dissection and highlight the importance of considering spontaneous coronary artery dissection as a differential diagnosis even in older, postmenopausal women.

    2015-01-01

    Acute cardiomyocyte necrosis in the infarcted heart generates damage-associated molecular patterns, activating complement and toll-like receptor/interleukin-1 signaling, and triggering an intense inflammatory response. Inflammasomes also recognize danger signals and mediate sterile inflammatory response following acute myocardial infarction (AMI). Inflammatory response serves to repair the heart, but excessive inflammation leads to adverse left ventricular remodeling and heart failure. In addition to local inflammation, profound systemic inflammation response has been documented in patients with AMI, which includes elevation of circulating inflammatory cytokines, chemokines and cell adhesion molecules, and activation of peripheral leukocytes and platelets. The excessive inflammatory response could be caused by a deregulated immune system. AMI is also associated with bone marrow activation and spleen monocytopoiesis, which sustains a continuous supply of monocytes at the site of inflammation. Accumulating evidence has shown that systemic inflammation aggravates atherosclerosis and markers for systemic inflammation are predictors of adverse clinical outcomes (such as death, recurrent myocardial in-farction, and heart failure) in patients with AMI.

    Full Text Available Yakup Altas, Ali Veysel Ulugg Department of Cardiology, Diyarbakir Gazi Yasargil Education and Research Hospital, Diyarbakir, Turkey Abstract: ST segment elevation is the most common electrocardiographic finding in acute myocardial infarction. ST elevation in chest leads generally represents left anterior descending artery occlusion, while elevation in DII and III, and aVF represents right coronary and circumflex artery occlusion. A female patient aged 66 years was admitted to our emergency service with ST elevation in leads DIII and aVF. A diagnosis of acute inferior myocardial infarction was made. The patient’s history included coronary artery bypass graft involving the left internal mammary artery to the left anterior descending coronary artery and aorta to the right coronary artery. The patient was taken to the cardiac catheterization laboratory for primary percutaneous coronary intervention and a lesion in the left anterior descending artery was identified. Additionally, the left subclavian artery was totally occluded. Following intervention to the lesion, the patient was discharged on day 4 of admission.

  3. Perfusion scintigraphy in acute myocardial infarction

    International Nuclear Information System (INIS)

    The Tc-99m sestamibi perfusion SPECT scintigraphy in acute myocardial infarction is a feasible method to assess the size of area at risk and the residual blood flow to this area as the most important determinants of final infarct size without any delay in treatment. In combination with a follow-up study final infarct size as well as myocardial salvage can be quantified. Clinical indications for the use of Tc-99m sestamibi scintigraphy are the noninvasive identification of arterial occlusion in patients suspected to acute myocardial infarction without electrocardiographic ST-elevation and the assessment of reperfusion success. In clinical trials Tc-99m sestamibi scintigraphy has proven to be a useful method to assess the impact of varying reperfusion therapies. The present review article discusses the indication, the study protocol, the interpretation of results and the clinical and scientifically importance of this method. (orig.)

    Full Text Available INTRODUCTION: Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. OBJECTIVE Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. METHODS A descriptive study was conducted of persons aged >25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room and location (jurisdiction of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. RESULTS A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008. In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged >75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively. CONCLUSIONS Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies

    1994-07-01

    Thrombolytic therapy has revolutionized the treatment of acute myocardial infarction by reducing mortality and preserving left ventricular function. It is relatively safe and cost-effective. However, it is currently underused in most countries. Patients in whom thrombolysis is indicated include those with ST elevation on the electrocardiogram or bundle branch block pattern who present within 12 hours of myocardial infarction; the indications should be widened to include the elderly, patients who have undergone nontraumatic cardiopulmonary resuscitation, and women during menstruation. The risk-benefit ratio should be assessed for the individual patient. Prehospital thrombolytic treatment has been shown to be feasible with the support of well-trained staff and resuscitation equipment, and may be cost-effective in communities with time delays before hospitalization greater than 1 hour. The most important strategy is to shorten the "door to needle" time in hospital. The importance of full infarct-related artery flow (Thrombolysis in Myocardial Infarction [TIMI] grade 3 flow) for preservation of ventricular function and survival has been documented in the second Thrombolysis Trial of Eminase in Acute Myocardial Infarction (TEAM 2) and the Global Utilization of Streptokinase and t-PA for Occluded Coronary Arteries (GUSTO) studies. Aspirin and heparin are beneficial adjunctive regimens to thrombolytic therapy but optimal epicardial reperfusion is achieved in only about half of patients. Improved thrombolytic, adjunctive antiplatelet, and antithrombotic regimens are required to achieve early full reperfusion, which is crucial to improve survival and quality of life. PMID:7919592

    The extent of myocardial damage occurring during acute myocardial infarction is time dependent, and there is abundant evidence from most clinical trials that mortality reduction is greatest in patients treated early with thrombolytic agents, although beneficial effects have been shown with treatment initiated up to 12 h after onset of symptoms. All studies on prehospital thrombolysis have conclusively shown the practicability and safety of patient selection and administration of the thrombolytic agent. The accuracy of diagnosis in the prehospital setting was comparable to trials of in-hospital thrombolysis, e.g., in the Myocardial Infarction Triage and Intervention Project (MITI) 98% of the patients enrolled had subsequent evidence of acute myocardial infarction. With regard to time savings, all randomized studies showed positive results. The smallest time gain was observed in the MITI trial: prehospital-treated patients received thrombolytic therapy an average of 33 min earlier than those treated in hospital. In the European Myocardial Infarction Project (EMIP) the difference in time between prehospital and hospital treatment was a median of 55 min. However, none of these trials was able to show a significant short-term mortality difference between the two groups. Only a meta analysis of five randomized studies with a combined median time gain of about 60 min showed a significant 17% reduction in short-term mortality for patients who received thrombolytic therapy in the prehospital phase. In the Grampian Region Early Anistreplase Trial (GREAT), a study performed in a more rural area than other studies, the time gain by prehospital initiation of thrombolysis was a median of 130 min. GREAT was the only study to date reporting a significant mortality benefit for prehospital-treated patients after 3 months and 1 year. In conclusion, prehospital thrombolysis is feasible and safe. Patients with acute myocardial infarction can be correctly identified and treated with

    Myocardial infarction, commonly known as heart attack, is caused by reduced blood supply and damages the heart muscle because of a lack of oxygen. Myocardial infarction initiates a cascade of biochemical and mechanical events. In the early stages, cardiomyocytes death, wall thinning, collagen degradation, and ventricular dilation are the immediate consequences of myocardial infarction. In the later stages, collagenous scar formation in the infarcted zone and hypertrophy of the non-infarcted zone are auto-regulatory mechanisms to partly correct for these events. Here we propose a computational model for the short-term adaptation after myocardial infarction using the continuum theory of multiplicative growth. Our model captures the effects of cell death initiating wall thinning, and collagen degradation initiating ventricular dilation. Our simulations agree well with clinical observations in early myocardial infarction. They represent a first step toward simulating the progression of myocardial infarction with the ultimate goal to predict the propensity toward heart failure as a function of infarct intensity, location, and size.

    An individual experiencing dyspnoea or syncope at high altitude is commonly diagnosed to have high-altitude pulmonary edema or cerebral edema. Acute myocardial infarction (AMI) is generally not considered in the differential diagnosis. There have been very rare cases of AMI reported only from Mount Everest. We report a case of painless ST segment elevation myocardial infarction (STEMI) that occurred while climbing Mount Kilimanjaro. A 51-year-old man suffered dyspnoea and loss of consciousness near the mountain peak, at about 5600 m. At a nearby hospital, he was treated as a case of high-altitude pulmonary edema. ECG was not obtained. Two days after the incident, he presented to our institution with continued symptoms of dyspnoea, light-headedness and weakness, but no pain. He was found to have inferior wall and right ventricular STEMI complicated by complete heart block. He was successfully managed with coronary angioplasty, with good recovery. PMID:26989121

    In acute myocardial infarction, the results of the trials with ACE-inhibitors have not been always good, in contrast with what has been observed in chronic heart failure. The comparison of these compounds with the placebo has demonstrated lack of reduction of mortality in the study CONSENSUS II, favorable results on the survival as first endpoint and on the secondary endpoints, as reinfarction, heart failure and stroke in the studies SOLVD, AIRE, GISSI 3, ISIS 4, and uncertain (interim report) results in the Chinese study. Nevertheless, the analysis of the recruitment of the patients with acute infarction and the way these patients have been treated seem to be the most important cause of the conflicting results. ACE-inhibitors have proved no efficacy in acute myocardial infarction without signs of left ventricular failure (CONSENSUS II), have worsened the clinical picture and the mortality in patients in shock or with severe heart failure in the acute phase. On the reverse, in presence of mild to moderate left ventricular dysfunction and failure, the use of ACE-inhibitors has been followed by reduction of mortality in the early (AIRE, GISSI 3, ISIS 4), medium term (GISSI 3) and long-term follow-up (up to 4 years in the AIRE study). In parallel with the reduction of the primary endpoint, also secondary endpoints have been favorably influenced by the different ACE-inhibitors. No differences have been observed among the different class of compounds. ACE-inhibitors seem, therefore, to have a clear indication in acute myocardial infarction with mild or moderate signs and symptoms of heart failure. PMID:7634258

  12. Thrombolysis for acute myocardial infarction: drug review.

    Science.gov (United States)

    Cundiff, David K

    2002-01-01

    The proof of efficacy of thrombolysis for acute myocardial infarction (AMI) depends on 9 randomized placebo-controlled trials totaling 58,511 patients. The meta-analysis of these trials showed an overall survival advantage of about 2% (11.5% vs 9.6%) in favor of thrombolysis. Iatrogenic deaths from thrombolysis complications occur in about 1% of AMI patients. Timely opening of the infarct-related artery (IRA) allowing myocardial reperfusion has been proposed to explain any survival advantage seen with thrombolysis ("open-artery hypothesis"). Angiographic data does not support the open-artery hypothesis as the mechanism of any benefit of thrombolysis. The "early hazard" (ie, increased mortality in the first 12 hours after thrombolysis) also suggests that the supposed survival benefit is due to something other than early reperfusion. The variable use of aspirin in the meta-analysis trials may have confounded the results and conclusions. In the 4 studies of the meta-analysis in which aspirin was used routinely (n = 21,144), the survival benefit was not statistically significant (P =.14). Lack of blinding in some studies and other methodologic problems may also call the conclusions of the meta-analysis into question. AMI registry reports comparing patients with and without thrombolysis have not borne out a significant survival advantage with thrombolysis. The National Registry of Myocardial Infarction (NRMI) registry data suggest that a significant number of AMI patients may be inappropriately receiving thrombolytics. An independent analysis of the NRMI mortality data adjusted for age and other risk factors would help determine whether thrombolysis for AMI improves survival. PMID:11965203

    This study aimed to describe the family experiences post-infarction. Qualitative, descriptive and exploratory research, carried out with six families of post-infarction patients. Data collection was conducted in families' homes, in the period of February to May of 2012, through observation and interviews with the family. The software Atlas Ti 6.2 was used to code the interviews and the data were explored with thematic analysis. Two categories emerged "Difficult times": immediate consequence of acute myocardial infarction for the families; and "We reeducate ourselves--we can adapt ourselves": current experience of families. The immediate post-infarction experience is permeated by several feelings, with the need for families to adapt to fit into the needs. The current experience shows changes in families due to the disease. The family is the main responsible for the care giving, although Nursing should exchange and share knowledge. PMID:24344600

    Kounis syndrome, also named as “allergic angina syndrome,” is a diagnosis in which exposure to an allergen causes mostly coronary spasm and rarely plaque rupture, resulting in ischemic myocardial events. Myocardial bridging is defined as an intramural segment of a coronary artery and its systolic compression by overlying fibers. Myocardial bridging generally has a benign prognosis and mostly affects the mid portion of left anterior descending coronary artery. However, some cases with myocardi...

    Full Text Available Determination of pre-hospital delay time of patients with acute myocardial infarction and seeking ways of speeding up the time for reperfusion is an important factor to lower mortality in these patients. This is a cross-sectional study to determine pre-hospital delay time, its components, and related causes and conditions, obtained in 375 patients with prolonged chest pain referred to four hospitals of Tehran University of Medical Sciences. Means of transport to hospital, reasons of ambulance disuse, decision time by the patient and finally the entire time of pre-hospital delay were specified. Suspected factors related to delays of more than 2 and 6 h were scrutinized with chi-square test. Rate of ambulance utility (18.9% directly correlated with age of patients (P<0.05. Principal motives to disuse ambulance insuccession were unrememberance (33.7%, access to private vehicle (32.8% and supposition of sufficient speed of personal reference (18.9%. Pre-hospital delay time was 8.1 ± 9.1 h (mean ± SD in whole patients and 7.6 ± 9.1 h in those with acute myocardial infarction. Delays of more than 2 and 6 hoccurred in 67.5% and 33.6% of patients, respectively. Decision time constitute three fourth of whole pre-hospital delay and was correlated with female gender, older age, history of diabetes, lower level of literacy and nocturnal onset of symptoms. In conclusion, a significant number of patients with acute myocardial infarction have pre-hospital delay of more than 2 and even 6 h, when golden time for thrombolytic therapy has already been elapsed.

  2. The immune system in atherosclerosis and in acute myocardial infarction

    Directory of Open Access Journals (Sweden)

    2009-08-01

    Full Text Available Acute myocardial infarction (AMI occurs when the atheromatous process prevents total blood flow through the coronary artery. It was previously thought that progressive luminal narrowing from the continued growth of smooth muscle cells (SMCs in the plaque was the main cause of infarction, however, angiographic studies, have identified culprit lesions that do not cause marked stenosis. Is now evident that plaque activation, rather than stenosis, precipitates ischemia and infarction. Coronary spasm could be involved to some extent, but most cases of AMI are due to the formation of an occluding thrombus on the surface of the plaque; the two major causes of coronary thrombosis are plaque rupture and endothelial erosion. Plaque rupture is detectable in 60- 70% of cases and preferentially occurs when the fibrous cap is thin and partly destroyed. One of the major challenges in modern cardiology is the knowledge of the factors that induce a silent atherosclerotic plaque shifting from a stable to a vulnerable form.

    The aim of this investigation was to determine whether H. pylori infection is an independent risk factor for acute myocardial infarction (AMI), determine is there a link between H. pylori infection and severity of disease. In this prospective, single centre study, were enrolled 100 patients with AMI and control group was consisted 93 healthy individuals. The results of this study showed no difference between H. pylori seropositivity distribution in the investigate and control group (29 vs. 26 %) and there was no significant difference on the severity of the disease. There was significant association in the patients with three and more risk factors, where the patients with lower blood pressure (124.4/77.4 vs. 145.9/87.7 mmHg) and better controlled diabetes (HbA1c 6.1% vs. 6.9%) had greater risk for AMI if they are H. pylori seropositive. The large multicentric trials would be needed to define a precise role of H. pylori infection on the developement of AMI. PMID:22053556

    Viable myocardial detection is very important in clinical practice. But the positive predictive value and specificities of all imagining modalities available are still relatively lower, and the causes may relative to the smooth of native or bridge coronary arteries after operation, the time to assess the function of viable myocardium, myocardial ischemia or damage after operation, the severity of left ventricular modification before revascularization and subendocardiac muscle scarring formation. The problems of viabile myocardial detection were still discussed here. (authors)

    The preventive and therapeutical effects of sodium valproate (SV), 200 mg/kg, on cardiac contractile disorders (developed pressure, rate-pressure products, dp/dt) were studied in rats having 2-day myocardial infarction (MI). The postinfarction rather than preinfarction use of SV substantially restricted the depressed resting left ventricular function. Given by two regimens, SV increased cardiac resistance to the maximum isometric load induced by 60-sec ligation of the ascending aorta. The cardioprotective effect of the drug was shown due to its positive chronotropic action rather than its inotropic one. Thus, SV may be used as an effective drug for the prevention and treatment of postinfarct cardiac dysfunctions. PMID:9235532

However it can cause various haemorrhagic and immunological complications. we report a patient who developed diffuse pulmonary hemorrhages (PH) and bilateral hemorrhagic pleural effusion after thrombolytic therapy with streptokinase for acute myocardial infarction. This was recognized by a drop of hematocrit,pulmonary infiltrates, hemorrhagic pleural effusion(HPE) and hypoxaemia. The diagnosis was confirmed by demonstration of iron-laden macrophages in bronchoalveolar lavage. The patient required mechanical ventilation and recovered successfully. This combination of PH and HPE following streptokinase therapy's extremely unusual and and has not been reported previously. (author)

  11. Acute Stress Decreases but Chronic Stress Increases Myocardial Sensitivity to Ischemic Injury in Rodents

    2016-01-01

    Cardiovascular disease (CVD) is the largest cause of mortality worldwide, and stress is a significant contributor to the development of CVD. The relationship between acute and chronic stress and CVD is well evidenced. Acute stress can lead to arrhythmias and ischemic injury. However, recent evidence in rodent models suggests that acute stress can decrease sensitivity to myocardial ischemia–reperfusion injury (IRI). Conversely, chronic stress is arrhythmogenic and increases sensitivity to myocardial IRI. Few studies have examined the impact of validated animal models of stress-related psychological disorders on the ischemic heart. This review examines the work that has been completed using rat models to study the effects of stress on myocardial sensitivity to ischemic injury. Utilization of animal models of stress-related psychological disorders is critical in the prevention and treatment of cardiovascular disorders in patients experiencing stress-related psychiatric conditions.

    Although maximal oxygen consumption (VO2max) and oxygen consumption at anaerobic threshold (VO2AT) were used to measure cardiac function, the clinical significance in acute myocardial infarction (MI) has not been reported. The purpose of this study was to compare VO2max and VO2AT between post-MI patients and healthy men and to correlate the parameters to other clinical measures. Forty-three active healthy men, 44 sedentary healthy men, and 43 post-MI patients were studied using incremental cycle exercise test. Their work rates, oxygen consumption, heart rates, oxygen pulses, ventilation, and other parameters at VO2max and VO2AT were determined with spirometer, gas concentration analyzer, and electrocardiograph. Anaerobic threshold was determined by analyzing the ventilatory parameters. Most of the exercise test parameters at VO2max were greatest in the active men, intermediate in the sedentary men, and least in the post-MI patients (P pressure products of the active men and sedentary men were not significantly different from each other and were greater than those of the post-MI patients (P < 0.01). In the post-MI patients, VO2max was inversely correlated to the peak serum level of creatine phosphokinase MB isoenzyme (P < 0.01) and associated with extensive infarction (P < 0.05). Most of the parameters at VO2AT were greater in the active men than in the sedentary men (P < 0.01) but not significantly different between the sedentary men and post-MI patients. In the post-MI patients, VO2AT was significantly correlated to left ventricular ejection fraction (P < 0.01) and associated with heart failure (P < 0.05). The results revealed that VO2max and VO2AT had different clinical significance in post-MI patients; VO2max was related to the infarct size, and VO2AT was related to the pumping function of heart.

    Aim: To assess the prognostic value of 64-section multidetector computed tomography (MDCT) to predict follow-up myocardial dysfunction and functional recovery after reperfusion therapy in patients with acute myocardial infarction (MI) as defined by echocardiography. Materials and methods: After reperfusion therapy for acute MI, 71 patients underwent two-phase contrast-enhanced MDCT and follow-up echocardiography. MDCT findings were compared with echocardiographic findings using kappa statistics. The areas under the receiver operating characteristic curves (AUCs) and the odds ratios (ORs) of early perfusion defects (EPD), delayed enhancement (DE), and residual perfusion defects (RPD) for predicting follow-up myocardial dysfunction and functional recovery were calculated on a segmental basis. Results: The presence of transmural EPD (EPD{sub TM}) or RPD showed good agreement (k = 0.611 and 0.658, respectively) with follow-up myocardial dysfunction, while subendocardial EPD (EPD{sub sub}) or subendocardial DE (DE{sub sub}) showed fair agreement with follow-up myocardial dysfunction (k = 0.235 and 0.234, respectively). The AUC of RPD (0.796) was superior (p < 0.001 and 0.031, respectively) to those of EPD{sub TM} (0.761) and DE{sub TM} (0.771). The presence of EPD{sub TM}, DE{sub TM}, and RPD were significant, independent positive predictors of follow-up myocardial dysfunction (OR = 6.4, 1.9, and 9.8, respectively). EPD{sub TM} was a significant, independent negative predictor of myocardial functional recovery (OR = 0.13). Conclusion: Abnormal myocardial attenuation on two-phase MDCT after reperfusion therapy may provide promising information regarding myocardial viability in patients with acute MI.

    Acute coronary syndrome is a common cause of sudden cardiac death. We present a case report of a 60-year-old man without a history of coronary artery disease who presented with ST-elevation myocardial infarction. During transportation to the hospital, he developed ventricular fibrillation (VF) and later pulseless electrical activity. Chest compressions with LUCAS 2 (Medtronic, Minneapolis, MN) automated mechanical compression-decompression device were initiated. Coronary angiography showed total occlusion of the left main coronary artery and primary percutaneous coronary intervention (PCI) was performed. After the PCI, his heart started to generate effective contractions and LUCAS could be discontinued. Return of spontaneous circulation was achieved after 90 minutes of cardiac arrest. The patient died of cardiogenic shock 11 hours later. An autopsy revealed a transmural anterolateral myocardial infarction but also massive subepicardial hemorrhage and interstitial edema and hemorrhages on histologic samples from regions of the myocardium outside the infarction itself and also from the right ventricle. These lesions were concluded to be a myocardial contusion. The true incidence of myocardial contusion as a consequence of mechanical chest compressions is not known. We speculate that severe myocardial contusion might have influenced outcome of our patient. PMID:27574387

    The importance of achieving rapid patency of the infarct-related artery during acute myocardial infarction has become well recognized. Early, sustained patency of the infarct-related vessel correlates with improved left ventricular function, better in-hospital outcomes, and lower mortality. Various strategies designed to improve early patency, including "prehospital" thrombolysis, use of an accelerated recombinant tissue plasminogen activator regimen, and immediate angioplasty have been studied. This paper reviews the importance of achieving early patency, the various strategies employed, and the evidence for their efficacy. Future directions in treatment of acute myocardial infarction are touched upon briefly. PMID:7549077

    Full Text Available BACKGROUND: Despite a substantial progress in diagnosis and therapy, acute myocardial infarction (MI is a major cause of mortality in the general population. A novel insight into the pathophysiology of myocardial infarction obtained by studying gene expression should help to discover novel biomarkers of MI and to suggest novel strategies of therapy. The aim of our study was to establish gene expression patterns in leukocytes from acute myocardial infarction patients. METHODS AND RESULTS: Twenty-eight patients with ST-segment elevation myocardial infarction (STEMI were included. The blood was collected on the 1(st day of myocardial infarction, after 4-6 days, and after 6 months. Control group comprised 14 patients with stable coronary artery disease, without history of myocardial infarction. Gene expression analysis was performed with Affymetrix Human Gene 1.0 ST microarrays and GCS3000 TG system. Lists of genes showing altered expression levels (fold change >1.5, p<0.05 were submitted to Ingenuity Pathway Analysis. Gene lists from each group were examined for canonical pathways and molecular and cellular functions. Comparing acute phase of MI with the same patients after 6 months (stable phase and with control group we found 24 genes with changed expression. In canonical analysis three pathways were highlighted: signaling of PPAR (peroxisome proliferator-activated receptor, IL-10 and IL-6 (interleukin 10 and 6. CONCLUSIONS: In the acute phase of STEMI, dozens of genes from several pathways linked with lipid/glucose metabolism, platelet function and atherosclerotic plaque stability show altered expression. Up-regulation of SOCS3 and FAM20 genes in the first days of myocardial infarction is observed in the vast majority of patients.

  14. Acute myocardial infarction in a young patient

    International Nuclear Information System (INIS)

    Myocardial infarction (MI) is considered to be the disease of the fifth and sixth decade as seen in the West but an earlier age incidence is not infrequently encountered in the South Asian population. However, occurrence of MI in the teen-age still remains a rare happening. We are reporting a case of a teenager, who suffered a myocardial infarction with cardiogenic shock and pulmonary edema on two separate occasions with ECG and biochemical evidence of myocardial infarction. An exercise stress test done in between the two episodes was negative at a workload of 13.5 METs. A coronary angiogram done after the second event revealed normal coronary arteries and a preserved left ventricular systolic and segmental function. Except for low HDL (high density lipoprotein) and mildly raised homocysteine levels, the patient did not have other conventional or novel risk factors for coronary artery disease. (author)

  16. Myocardial bridge: The cause of angina in a young man

    International Nuclear Information System (INIS)

    Myocardial bridging is basically the systolic narrowing of epicardial coronary arteries, secondary to their tunneled course in myocardium. Though it is a benign condition it can have the symptoms like acute coronary syndrome, arrhythmias and sudden cardiac death. We report a 32-year-old male, who presented with typical exertional angina, had positive exercise treadmill and thallium-201 test. Coronary angiography revealed myocardial bridge of distal left anterior descending coronary artery. He was put on β-blockers and was doing well at 8 years of follow-up

    2016-07-01

    The success of primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is often hampered by incomplete microvascular myocardial reperfusion owing to distal embolization of thrombus resulting in microvascular obstruction. To address this problem, thrombus aspiration devices have been developed that can be used to evacuate coronary thrombus either manually or mechanically. Thrombus aspiration has the potential to reduce the local thrombus load, minimize the need for balloon predilatation, facilitate direct stenting, prevent distal embolization, and ultimately improve myocardial reperfusion. Furthermore, thrombus aspiration has enabled us to study coronary thrombus in vivo, and has facilitated recognition of distinct mechanisms of coronary thrombosis. Clinical trials focusing on manual thrombus aspiration in primary PCI have generally shown improved myocardial reperfusion. However, in two large trials powered for clinical end points, no reduction in 1-year mortality or other adverse clinical events was observed with the use of this strategy. Moreover, one of these trials showed a marginally increased risk of stroke. Consequently, current guidelines do not recommend routine use of thrombus aspiration. Future studies should focus on the identification of subgroups of patients with STEMI who might derive benefit from manual thrombus aspiration, and establish the effect of operator performance on the efficacy and safety of the procedure.

    Metanephric adenoma (MA) is a rare neoplasm that acounts for 0.2% of adult renal neoplasms. MAs are typically discover incidentally during detailed examinations for nonspecific symptoms such as abdominal or flank pain, hematuria, fever and palpable abdominal mass. Additionally, polycythemia has occasionally been reported as well. Herein we describe a case of metanephric adenoma which was an incidental finding in the course of a clinical autopsy in a patient with complete AV block and polycythemia. Histologically, the tumor was composed of small and uniform tubular structures reminiscent of renal tubuli, without signs of cellular atypia and pleomorphism. Such tumor histomorphology was consistent with the diagnosis of metanephric adenoma. Thrombosis is a common complication of polycythemia that often causes death. Polycythemia with an increasing number of blood cells causes hyperviscosity and, in 20-40% of cases, lethal thrombosis or hemorrhage. Hyperviscosity and coronary artery disease in our patient caused acute myocardial infarction with the subsequent rupture of posterior left ventricle wall and hemopericardium. PMID:27471365

    Results on revealing a possible relationship between solar activity (SA) and geomagnetic activity (GMA) and acute myocardial infarction (AMI) morbidity are presented. Studies were based on medical data covering the period from 1.12.1995 to 31.12.2004 and concerned daily distribution of patients with AMI diagnose (in total 1192 cases) from Sofia region on the day of admission at the hospital. Analysis of variance (ANOVA) was applied to check the significance of GMA intensity effect and the type of geomagnetic storms, those caused by Magnetic Clouds (MC) and by High Speed Solar Wind Streams (HSSWS), on AMI morbidity. Relevant correlation coefficients were calculated. Results revealed statistically significant positive correlation between considered GMA indices and AMI. ANOVA revealed that AMI number was signifi- cantly increased from the day before (-1st) till the day after (+1st) geomagnetic storms with different intensities. Geomagnetic storms caused by MC were related to significant increase of AMI number in comparison with the storms caused by HSSWS. There was a trend for such different effects even on -1st and +1st day.

    Full Text Available The purpose of the study was to analyze morphological reactions of mitochondrial apparatus of atrial contractive cardiomyocites in rats on the acute myocardial ischemia. Modeling of the acute myocardial ischemia in rats was realized by daily introduction of vasopressin intraperitoneum in dosage 1 Ed of rat weight. Morphological research comprised both light and electronic microscopy of myocardium of right and left atria, right and left auricles, and also interatrial septum. Stereological estimation of several indexes was carried out: the compactness of mitochondria, numeral compactness of mitohondria, surface area of external mitochondrial membrane, compactness of mitochondrial cristae, number of mitochon-drial cristae, surface area of internal mitochondrial membrane, degree of cristae orientation, coefficient of mitochondrial sphericity, volume of mitochondrium, quantitative correlation of types of mitochondria. It was shown that the reaction of different types of mitochondria on development of acute myocardial ischemia in atrial contractive cardiomyocites depends on the structural-metabolic type of mitochondria. Under the acute myocardial ischemia the moderate diffuse reduction of mitochondrial apparatus of contractive cardiomyocites takes place that is accompanied by the prolonged renewal of high-energy mitochondria and causes energetical limitation of contractive function of atrial myocardium.

    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 The aim of the investigation was to study gene regulation of apoptosis in acute myocardial infarction and during the treatment, and assess the effect of levocarnitine (Elcar on gene expression of Fas-dependent apoptosis. Materials and Methods. We examined 28 patients with Q-myocardial infarction included in the study within the first 24 h of the disease and followed up during the treatment course. The patients were divided into two groups: group 1 (n=10 consisted of patients with standard treatment (anti-aggregants, ACE inhibitors, and anti-anginal agents — if indicated; group 2 (n=18 — those patients, who received standard treatment with Elcar (levocarnitine intravenously, in 5% glucose normal saline, at the dose of 3.0 g a day for three days. For the following 7 days the patients were given Elcar per os, 4.0 g a day. A control group (group 3 (n=18 consisted of healthy subjects. All patients underwent general examination, ECG, echocardiography, genetic research: we determined mRNA gene expression of mFas and sFas using real-time polymerase chain reaction thrice in each patient — on admission, after 1 week treatment, and at the end of the second week of treatment. Results. Apoptotic gene expression in patients with Q-infarction was found to be increased compared to the norm, the increase lasting for a longer period than acute myocardial infarction itself. This fact enables to explain the cause of prolonged apoptosis by the sustained activity of apoptosis-inducing genes. The use of levocarnitine promotes the normalization of an increased level of gene expression, and has a cardioprotective effect that is important in acute myocardial infarction treatment.

    Symptoms of an acute myocardial infarction are a common reason for calling the emergency physician. Pre-hospital mortality caused by cardiac infarction is constantly high. The main potential for decreasing infarction mortality lies in the pre-hospital period. The problems and prospects of treatment in the early period are described in the case of a 73-year-old patient with an acute anterior infarction. The diagnostic and therapeutic approach is shown and discussed in this concrete case, taking into consideration the guidelines for diagnostics and therapy of acute myocardial infarction in the pre-hospital period of the German Society for Cardiology. A particular focus is the management of pre-hospital thrombolysis, the preconditions, realization and risks of which are described. In this context, the experience and competence of the emergency physician is prerequisite for the exact diagnosis and therapy. Furthermore, the importance of a smooth transition from pre-hospital therapy to intensive care is emphasized. PMID:12666508

    Cardiovascular disease, including acute myocardial infarction (AMI), is the leading cause of death in the United States and was the primary disease category among hospital discharges in 1996. Efforts to improve hospital care of patients with AMI should be measured and assessed routinely for appropriateness of care and improvement of medical staff performance. The National Registry of Myocardial Infarction (NRMI), an observational Phase IV study, has enrolled > 1 million AMI patients since 1990, and is now in its third phase. NRMI 3 collects patient data and facilitates the measurement of improvement in care and outcomes, while allowing participating institutions to benchmark their performance against national, state, and like-hospital data. Three measures from NRMI 3 are accepted for the Joint Commission on Accreditation of Healthcare Organizations' ORYX initiative: (1) aspirin use within 24 hours of AMI diagnosis; (2) door-to-drug time for fibrinolysis; and (3) no initial reperfusion strategy given to eligible patients.

    Drug-induced pancreatitis has been reported rarely. Bortezomib is a selective and reversible proteasome inhibitor used for the treatment of patients with multiple myeloma (MM). Recently, one case report about acute pancreatitis (AP) caused by bortezomib was published in the international literature. Herein we report a case of AP in a 67-year-old male on bortezomib therapy. On the fourth day after the first administration of bortezomib, the patient admitted to the hospital with symptoms of AP. The common etiological factors for AP were all excluded. Than the patient was diagnosed as bortezomib-induced pancreatitis. PMID:23561979

  17. Thromboxane B2 formation in patients with acute myocardial infarction

    International Nuclear Information System (INIS)

    Thromboxane A2 is a stable metabolite of thromboxane B2 which production and release were reported with many of the risk factors related to coronary-artery disease. In 18 patients with acute transmural myocardial infarction serial determinations of thromboxane B2 were performed in the blood having clotted at 370C for 30 min. Significantly less (p < 0.05) of thromboxane B2 was formed in the first week after infarction compared to the control group. Thromboxane B 2 formed in the blood of these patients increased slightly in the recovery period but was still lower than in healthy population. Since thromboxane A2 exerts deleterious effects upon myocardial performance an adaptive protective effect of the decreased thromboxane synthesis in patients with myocardial infarction was suggested.

    2005-01-01

    Full Text Available Introduction Ischemic preconditioning is a phenomenon in which brief episodes of ischemia and reperfusion increase myocardial tolerance and substantially reduce the infarction size. Case report Two patients with acute left anterior descending artery occlusion received fibrinolytic therapy within 6 hours of symptom onset, but nevertheless developed myocardial infarctions of different size. The first patient, without a history of preinfarction angina, developed a large anterior infarction, because there was no time for ischemic preconditioning or development of coronary collateral vessels. The second patient, with a 4-day history of preinfarction angina, had a more favorable outcome-he developed apical necrosis, with greater myocardial viability in the infarct-related area. Conclusion The beneficial effects of angina occurring 24-48h before infarction are resulting from ischemic preconditioning, which reduces cardiac mortality, infarct size and occurrence of life-threatening ventricular arrhythmias. .

    A myocardial infarction is a rare complication which can occur after an exercise stress test. We report a 48-year-old male who was referred to the Mildura Cardiology Practice, Victoria, Australia, in August 2014 with left-sided chest pain. He underwent an exercise stress test which was negative for myocardial ischaemia. However, the patient presented to the Emergency Department of the Mildura Base Hospital 30 minutes after the test with severe retrosternal chest pain. An acute anteroseptal ST segment elevation myocardial infarction was observed on electrocardiography. After thrombolysis, he was transferred to a tertiary hospital where coronary angiography subsequently revealed significant left anterior descending coronary artery stenosis. Thrombus aspiration and a balloon angioplasty were performed. The patient was discharged three days after the surgical procedure in good health.

    1988-01-01

    Recent studies have shown that patients with acute myocardial infarction (AMI) are magnesium-deficient and develop an additional transient decrease in serum magnesium concentrations (S-Mg c) during the acute phase of the infarct. Animal experiments, as well as studies on humans, have indicated...... that the acute decrease in S-Mg c as well as a more chronic magnesium (Mg) deficiency state are harmful to the myocardium in the setting of acute ischaemia. This knowledge has led during the last couple of years to the performance of four double-blind placebo controlled studies in which the effect of i.......v. magnesium therapy on mortality and incidence of arrhythmias in patients with AMI has been evaluated. Magnesium treatment more than halved the acute mortality and incidence of arrhythmias requiring treatment in three of the four intervention studies.

    Full Text Available Depression is an adverse prognostic factor after an acute myocardial infarction (MI, and an increased propensity toward emotionally-driven myocardial ischemia may play a role. We aimed to examine the association between depressive symptoms and mental stress-induced myocardial ischemia in young survivors of an MI.We studied 98 patients (49 women and 49 men age 38-60 years who were hospitalized for acute MI in the previous 6 months. Patients underwent myocardial perfusion imaging at rest, after mental stress (speech task, and after exercise or pharmacological stress. A summed difference score (SDS, obtained with observer-independent software, was used to quantify myocardial ischemia under both stress conditions. The Beck Depression Inventory-II (BDI-II was used to measure depressive symptoms, which were analyzed as overall score, and as separate somatic and cognitive depressive symptom scores.There was a significant positive association between depressive symptoms and SDS with mental stress, denoting more ischemia. After adjustment for demographic and lifestyle factors, disease severity and medications, each incremental depressive symptom was associated with 0.14 points higher SDS. When somatic and cognitive depressive symptoms were examined separately, both somatic [β = 0.17, 95% CI: (0.04, 0.30, p = 0.01] and cognitive symptoms [β = 0.31, 95% CI: (0.07, 0.56, p = 0.01] were significantly associated with mental stress-induced ischemia. Depressive symptoms were not associated with ischemia induced by exercise or pharmacological stress.Among young post-MI patients, higher levels of both cognitive and somatic depressive symptoms are associated with a higher propensity to develop myocardial ischemia with mental stress, but not with physical (exercise or pharmacological stress.

    Results of collaborative studies on revealing a possible relationship between solar activity (SA) and geomagnetic activity (GMA) and pre-hospital acute myocardial infarction (AMI) morbidity are presented. Studies were based on medical data from Bulgaria and Azerbaijan. Bulgarian data, covering the period from 01.12.1995 to 31.12.2004, concerned daily distribution of number of patients with AMI diagnose (in total 1192 cases) from Sofia Region on the day of admission at the hospital. Azerbaijani data contained 4479 pre-hospital AMI incidence cases for the period 01.01.2003-31.12.2005 and were collected from 21 emergency and first medical aid stations in Grand Baku Area (including Absheron Economical Region with several millions of inhabitants). Data were "cleaned" as much as possible from social and other factors and were subjected to medical and mathematical/statistical analysis. Medical analysis showed reliability of the used data. Method of ANalysis Of VAriance (ANOVA) was applied to check the significance of GMA intensity effect and the type of geomagnetic storms - those caused by magnetic clouds (MC) and by high speed solar wind streams (HSSWS) - on AMI incidences. Relevant correlation coefficients were calculated. Results were outlined for both considered data. Results obtained for the Sofia data showed statistically significant positive correlation between considered GMA indices and AMI occurrence. ANOVA revealed that AMI incidence number was significantly increased from the day before till the day after geomagnetic storms with different intensities. Geomagnetic storms caused by MC were related to significant increase of AMI number in comparison with the storms caused by HSSWS. There was a trend for such different effects even on -1st and +1st day for the period 1995-2004. Results obtained for the Baku data revealed trends similar to those obtained for Sofia data. AMI morbidity increment was observed on the days with higher GMA intensity and after these days

However, a considerable number of men and women arrive at the emergency department outside of the time frame for thrombolytic and angioplasty effectiveness. This is especially true for women who have been shown to delay longer than men due to their prehospital decision-making process utilized. With a mean total delay time greater than 4 hours, the time interval from symptom onset to transport activation to the hospital consumes the majority of the prehospital phase of emergency cardiac care. The health belief model, self-regulation model, theory of reasoned action, and theory of planned behavior have all been used to describe the prehospital decision-making process of both men and women with an AMI and the variables that impact that process. These models have identified the importance of symptom attribution to cardiac-related causes as a target variable for research and interventions related to care-seeking behavior. PMID:18340239

    Myocardial free wall rupture is a catastrophic complication of acute myocardial infarction, and prognosis will depend on the prompt diagnosis by echocardiography, extension of infarct size, and prompt surgical treatment. Free wall rupture concomitant with ventricular septal defect (VSD) may be more complicated for management. A case of a 69-year-old man with myocardial free wall rupture and VSD following acute anterior myocardial infarction is presented.

    Full Text Available Mortality in patients with acute myocardial infarction (AMI has decreased significantly and appears to be the result of current reperfusion therapeutic strategies. Reperfusion itself may develop into reperfusion injury. Therefore, management of these patients poses several challenges, such as diagnosing and managing heart failure, identifying persistent or inducible ischaemia, estimating the need for anticoagulation, and assessing overall cardiovascular risk. This case presentation will demonstrate the impact of cardiac magnetic resonance imaging (MRI in the assessment of the pathophysiology of AMI in the current reperfusion era. Cardiac MRI can provide a wide range of clinically useful information which will help clinicians to manage and choose specific therapeutic strategies for AMI patients.

  13. Risk factors in young patients of acute myocardial infarction

    International Nuclear Information System (INIS)

    Background: Ischemic heart disease is a leading cause of death throughout the world. CAD has been recognized among younger age group more frequently in recent years. Very limited data is available regarding the prevalence of various risk factors in our younger patients that is why this study was planed. Objectives of the study were to look for the risk factors most prevalent in our young patient of first Acute Myocardial Infarction. And to also look for the number of Risk Factors present in each patient. Methods: We studied 100 consecutive patients from 16-45 years of age presenting with first acute MI. Twelve risk factors were studied namely, gender, family history of premature CAD, smoking hypertension, diabetes, dyslipidemia, obesity, mental stress (type A personality), alcohol, oral contraceptive pills (OCPs), physical activity, and diet. We divided the patients into two groups. Group A with patients 35 years of age or less and group B with patients 36-45 years of age. All risk factors were compared in both the groups. Results: Smoking, diabetes mellitus, dyslipidemia and hypertension were statistically different between the two groups. Frequency wise risk factors were lined up as male sex (91%) Diet (66%), Dyslipidemia (62%), smoking (46%), Type A personality(46%), family history (32%), diabetes mellitus (28%), sedentary lifestyle (26%), hypertension (22%), obesity (17%), alcohol (3%), and OCPs (0%) Most of the patients that is 94% had 3 or more risk factors. Conclusion: Smoking, hypertension, diabetes and dyslipidemia are the major modifiable risk factors in our young adults. If a young male who is smoker or a young female who is diabetic, presents in emergency room with chest pain, always suspect coronary artery disease. Other conventional risk factors are also prevalent but alcohol and OCPs are not a major health problem for us. (author)

  14. Acute oedema in the evaluation of microvascular reperfusion and myocardial salvage in reperfused myocardial infarction with cardiac magnetic resonance imaging

    International Nuclear Information System (INIS)

    The accurate measurement of myocardial salvage is critical to the ongoing refinement of reperfusion strategies in acute myocardial infarction (AMI). Cardiac magnetic resonance imaging (CMR) can define the area at risk in AMI by the presence of myocardial oedema, identified by high signal intensity on T2-weighted imaging with a short inversion time inversion-recovery (STIR) sequence. In addition, myocardial necrosis can be identified with CMR delayed contrast enhanced imaging. In this prospective study we examined the relationship of acute oedema and necrosis with impaired microvascular reperfusion. We also evaluated acute oedema as a marker of the area at risk in AMI, for the purposes of documenting myocardial salvage. CMR was performed on 15 patients with (AMI), within 24 h of successful percutaneous coronary intervention (PCI). Left ventricular (LV) systolic dysfunction was defined by a systolic thickening 0.5). The extent of myocardial salvage correlated with recovery of systolic function (R = 0.241, P < 0.05), which was strongest in LV segments with severely reduced systolic function (R = 0.422, P < 0.01). Conclusions: In acutely reperfused AMI, oedema can be used to identify the area at risk for the purpose of calculating myocardial salvage. The correlation between myocardial oedema and reperfusion status suggests a pathological role of acute oedema in the impairment of microvascular reperfusion.

    The mechanism mediating the development of ventricular arrhythmia (VA) after acute myocardial infarction (AMI) is still uncertain. Thrombin receptor (TR) activation has been proven to be arrhythmogenic in many other situations, and we hypothesize that it may participate in the genesis of post-AMI VA. Using a left coronary artery ligation rat model of AMI, we found that a local injection of hirudin into the left ventricle (LV) significantly reduced the ratio of VA durations to infarction sizin...

    2013-12-01

    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 Background/Aim. The heart has traditionally been considered as a static organ without capacity of regeneration after trauma. Currently, the more and more often asked question is whether the heart has any intrinsic capacities to regenerate myocytes after myocardial infarction. The aim of this study was to present the existence of the preserved muscle fibers in the myocardial scar following myocardial infarction as well as the presence of numerous cells of various size and form that differently reacted to the used immunohistochemical antibodies. Methods. Histological, histochemical and immunohistochemical analyses of myocardial sections taken from 177 patients who had died of acute myocardial infarction and had the myocardial scar following myocardial infarction, were carried out. More sections taken both from the site of acute infarction and scar were examined by the following methods: hematoxylin-eosin (HE, periodic acid schiff (PAS, PAS-diastasis, Masson trichrom, Malory, van Gieson, vimentin, desmin, myosin, myoglobin, alpha actin, smoth muscle actin (SMA, p53, leukocyte common antigen (LCA, proliferating cell nuclear antigen (PCNA, Ki-67, actin HHF35, CD34, CD31, CD45, CD45Ro, CD8, CD20. Results. In all sections taken from the scar region, larger or smaller islets of the preserved muscle fibers with the signs of hypertrophy were found. In the scar, a large number of cells of various size and form: spindle, oval, elongated with abundant cytoplasm, small with one nucleus and cells with scanty cytoplasm, were found. The present cells differently reacted to histochemical and immunohistochemical methods. Large oval cells showed negative reaction to lymphocytic and leukocytic markers, and positive to alpha actin, actin HHF35, Ki-67, myosin, myoglobin and desmin. Elongated cells were also positive to those markers. Small mononuclear cells showed positive reaction to lymphocytic markers. Endothelial and smooth muscle cells in the blood vessel walls

    Coronary artery aneurysms that occur in 25% of untreated Kawasaki disease (KD) patients may remain clinically silent for decades and then thrombose resulting in myocardial infarction. Although KD is now the most common cause of acquired heart disease in children in Asia, the United States, and Western Europe, the incidence of KD in Egypt is unknown. We tested the hypothesis that young adults in Egypt presenting with acute myocardial ischemia may have coronary artery lesions because of KD in childhood. We reviewed a total of 580 angiograms of patients ≤40 years presenting with symptoms of myocardial ischemia. Coronary artery aneurysms were noted in 46 patients (7.9%), of whom 9 presented with myocardial infarction. The likelihood of antecedent KD as the cause of the aneurysms was classified as definite (n = 10), probable (n = 29), or equivocal (n = 7). Compared with the definite and probable groups, the equivocal group had more traditional cardiovascular risk factors, smaller sized aneurysms, and fewer coronary arteries affected. In conclusion, in a major metropolitan center in Egypt, 6.7% of adults aged ≤40 years who underwent angiography for evaluation of possible myocardial ischemia had lesions consistent with antecedent KD. Because of the unique therapeutic challenges associated with these lesions, adult cardiologists should be aware that coronary artery aneurysms in young adults may be because of missed KD in childhood.

    The accurate measurement of myocardial salvage is critical to the ongoing refinement of reperfusion strategies in acute myocardial infarction (AMI). Cardiac magnetic resonance imaging (CMR) can define the area at risk in AMI by the presence of myocardial oedema, identified by high signal intensity on T{sub 2}-weighted imaging with a short inversion time inversion-recovery (STIR) sequence. In addition, myocardial necrosis can be identified with CMR delayed contrast enhanced imaging. In this prospective study we examined the relationship of acute oedema and necrosis with impaired microvascular reperfusion. We also evaluated acute oedema as a marker of the area at risk in AMI, for the purposes of documenting myocardial salvage. CMR was performed on 15 patients with (AMI), within 24 h of successful percutaneous coronary intervention (PCI). Left ventricular (LV) systolic dysfunction was defined by a systolic thickening <40% (severe <20%). Microvascular reperfusion was evaluated during the acute phase of contrast wash-in. CMR was repeated 3 months post-PCI to evaluate recovery of LV function and final infarct size. Myocardial salvage was defined as the percentage of the area at risk that was not infarcted on follow up CMR. There was a significant correlation between impaired microvascular reperfusion and the extent of segmental oedema (R = 0.363, P < 0.01), but not myocardial necrosis (R = 0.110, P > 0.5). The extent of myocardial salvage correlated with recovery of systolic function (R = 0.241, P < 0.05), which was strongest in LV segments with severely reduced systolic function (R = 0.422, P < 0.01). Conclusions: In acutely reperfused AMI, oedema can be used to identify the area at risk for the purpose of calculating myocardial salvage. The correlation between myocardial oedema and reperfusion status suggests a pathological role of acute oedema in the impairment of microvascular reperfusion.

    Full Text Available The use of intravenous thrombolytic agents has revolutionised the treatment of acute myocardial infarction. However, the improvement in mortality rate achieved with these drugs is tempered by the risk of serious bleeding complications, including intracranial haemorrhage. Tenecteplase is a genetically engineered mutant tissue plasminogen activator. Haemorrhagic complications of tissue plasminogen activator (tPA are well known. Compared to other tPAs, tenecteplase use leads to lower rates of bleeding complications. Here, we report a case of unusual site of spontaneous bleeding, intralingual haematoma during tenecteplase therapy following acute myocardial infarction, which caused significant upper airway obstruction and required tracheotomy to maintain the patient’s airway. Clinical dilemmas related to securing the airway or reversing the effects of tissue plasminogen activator are discussed.

    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.

    Full Text Available BACKGROUND and AIMS: Mental stress is considered to be a precipitating factor in acute coronary events. We aimed to assess the association of subjective or 'perceived' mental stress with the occurrence of acute coronary events. SETTINGS AND DESIGN: Prospective case-control survey was carried out in a referral teaching hospital. subjects & METHODS: Consecutive patients with acute myocardial infarction and ST elevation on electrocardiogram who were admitted to the Coronary Care Unit of a referral teaching hospital were enrolled in the study as cases. Controls were unmatched and were enrolled from amongst patients with coronary artery disease who did not have recent acute coronary events. Subjective Stress Functional Classification (SS-FC for the preceding 2-4 weeks was assessed and assigned four grades from I to IV as follows: I - baseline, II - more than usual but not affecting daily routine, III - significantly high stress affecting daily routine and IV - worst stress in life. STATISTICAL ANALYSIS: Proportions of different characteristics were compared using chi-square test with Yates continuity correction. Student's unpaired t test was applied for mean age. 'p' value of < 0.05 was considered statistically significant. RESULTS: SS-FC could be reliably (99% and easily assessed. Eighty (53% of the total 150 patients with acute MI reported 'high' levels of stress (stress class III and IV. This is in contrast to only 30 (20% of 150 healthy controls reporting high stress for the same period (p value < 0.001. CONCLUSION: Patients with acute myocardial infarction report a higher subjective mental stress during 2 to 4 weeks preceding the acute coronary event.

    Although there has been great progress in reperfusion therapy, the role of coronary reperfusion for elderly patients with acute myocardial infarction has not been fully investigated. In general, mean age of the subjects in major trials was about 60 years old and approximately only 10 to 15% of patients were over age 75. On the other hand, large-scale registries such as the US national registry of myocardial infarction (NRMI) showed a higher prevalence of elderly (especially women) in the clinical setting. This discrepancy may be due to the fact that elderly patients with myocardial infarction have some difficulties in the treatment such as severe multi-vessel coronary lesions, non-cardiac complications and relatively high prevalence of adverse reactions to reperfusion therapy. Here we focus on the situation of elderly patients (especially those 75 years or older) with myocardial infarction in the "real world" clinical setting, showing the clinical changes and outcome of our registry in rural Japan: the Kochi AMI (KAMI) registry.

    2010-01-01

    Full Text Available Problem statement: Myocardial infarction is the combined result of environmental and personal factors. Prothrombotic factors might play an important role in this phenomenon. Inflammation plays a pivotal role in atherosclerosis and coronary heart disease. Cardiotrophin-1 (CT-1, a member of the IL-6 family of cytokines, was identified as a growth factor for cardiac myocytes that induces cardiomyocyte hypertrophy and stimulates cardiac fibroblasts, protects myocytes from cell death. This study was designed to investigate whether plasma concentration of Cardiotrophin-1 (CT-1, in patients who had the first acute myocardial infarction and to analyze their relationship with traditional cardiovascular risk factors. Approach: This study was carried out on 45 patients with Acute Myocardial Infarction (AMI in their first 24 h of admission as case group and 36 healthy matched individuals were studied as the control. Plasma level of cardiotrophin-1 was determined by enzyme-linked immunosorbent assay and the results were compared. Results: Plasma CT-1 levels in the patients with AMI on admission 615.279±5.109 pmol L-1 were significantly higher than those in the control group 534.767±6.750 pmol L-1 (p = 0.001. Plasma CT-1 level was not correlated with diabetes mellitus, hyperlipidemia, sex, age and smoking. Conclusion: Our findings suggested that high plasma CT-1 level in patients with AMI is indicative of hypercoagulable state that is not related to the traditional cardiovascular risk factors.

    2010-01-01

    Full Text Available Problem statement: Myocardial infarction is the combined result of environmental and personal factors. Data concerning the relation between anti-Phospholipid (aPL antibodies and myocardial infarction in subjects without evidence of overt autoimmune disease are conflicting. Anticardiolipin antibody is detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of Anticardiolipin antibody in Acute Myocardial Infarction (AMI might shed light on etiologic mechanisms in the pathogenesis of acute coronary syndromes. The purpose of the present study was to determine association of plasma aPL antibodies, namely, anti-Cardiolipin (aCL antibodies, with AMI. Approach: This study recruited 45 patients with the diagnosis of AMI according to WHO criteria in their first 24 h of admission. Thirty six matched individuals were studied as the control group with normal coronary artery angiography. Samples were tested for IgG-class antibodies to cardiolipin by an ELISA and the results were compared. Results: There were not significant differences between plasma level of aCLAs IgG in the patients with AMI on admission ant the control group. Also aCLAs IgG was not correlated with hypertension, diabetes mellitus, hyperlipidemia, sex, age and smoking. Conclusion: Our findings suggest that aCLAs IgG are not indicative of hypercoagulable state in patients with AMI.

    2006-01-01

    Full Text Available Introduction. According to the published guidelines for the management of acute coronary syndromes (ACS, treatment of acute ST-elevated myocardial infarction is based on rapid revascularization, either mechanical or pharmacological. Pharmacological revascularization consists of fibrinolytic therapy with antiplatelet and anticoagulant therapy. In regard to the anticoagulant therapy, low molecular weight heparins (LMWHs are of special importance. LMWHs cause less complications (bleeding, thrombocytopenia, better bioviability in comparison with unfractionated heparin (UFH. Some studies on use of LMWHs in ACS, show that LMWHs are equally efficient and safe as UFH, causing less complications (different types of hemorrhagic complications (ESSENCE, TIMI 11B (enoxaparin, FRAXIS - fraxiparin, whereas some studies show better efficacy and safety of enoxaparin in therapy of acute ST-elevated myocardial infarction (ASSENT 3, ASSENT 3 PLUS, HART II, AMI-SK. Material and methods. Inclusion criteria: acute anterior myocardial infarction with ST-elevation, first myocardial infarction, no other structural heart defects, no signs of cardiogenic shock. Our study included 30 patients receiving fibrinolytic therapy with streptokinase, antiplatelet therapy and LMWH during 6 days, and 30 patients receiving UFH instead of LMWH. The follow-up period lasted for 6 months. Results. Significantly more patients receiving unfractionated heparin presented with major adverse cardiac events (73.3% in regard to patients in the study group (44,2% nadroparin, 39.8% enoxaparin (p=0.025. In the group receiving UFH, 6.7% patients had hemorrhagic complications, while none of patients receiving LMWHs. An equal number of patients died. Conclusion. Patients who were treated with LMWHs experienced less major adverse cardiac events and lower mortality. None suffered from hemorrhagic complications. .

    Full Text Available Psychological reactions, risk health behavior and cardiac parameters can influence rehospitalization after acute myocardial infarction.The aim of the paper was to determine the presence of psychological reactions and risk health behavior in patients with acute myocardial infarction on admission as well as the differences after six months.The research included thirty-trhee patients of both sexes, who were consecutively hospitalized due to acute myocardial infarction. A prospective clinical investigation involved the following: semi-structured interview, Mini International Neuropsychiatric Interview (M.I.N.I for pcychiatric disorders, Beck Anxiety Inventory (BAI for measuring the severity of anxiety, Beck Depression Inventory (BDI for measuring the severity of depression, KON-6 sigma test for aggression, Holms-Rahe Scale (H-R for exposure to stressful events, and Health Behavior Questionnaire: alcohol consumption, cigarette smoking, lack of physical activity. Measurement of the same parameters was done on admission and after six months. The differences were assessed using the t-test and chi-square test for p<0.05.On admission, anxiety (BAI=8.15±4.37 and depression (BDI=8.67±3.94 were mild without significant difference after six months in the group of examinees. Aggression was elevated and significantly lowered after six monts (KON-6 sigma =53,26±9, 58:41,42±7.67, t=2,13 for p<0.05. Exposure to stressful events in this period decreased (H-R=113.19±67.37:91,65±63,81, t=3,14 for p<0.05; distribution of physical activity was significantly higher compared to admission values (54.83%: 84.84%. χ2=5.07 for p<0.01.In the group of examinees with acute myocardial infarction in the period of six months, anxiety and depression remained mildly icreased, while the levels of aggression and exposure to stressful events were lowered.

    Allergic symptoms accompanied by myocardial ischemic symptoms are defined as Kounis syndrome. Etofenamate is a safe and effective non-steroidal antiinflammatory drug that has widespread utilization. We hereby present a 71-year-old man with Kounis syndrome. Following intramuscular 1 g etofenamate injection, the clinical presentation when admitted to the emergency department (ED) was erythematous rash, pruritus, nausea and vomiting, dizziness, diaphoresis, and chest pain resulting in cardiopulmonary arrest. After 10 minutes of successful cardiopulmonary resuscitation, the electrocardiogram revealed acute inferior myocardial infarction. Patients who admit to the ED with allergic symptoms accompanied by chest pain should consider Kounis syndrome for prompt management. Electrocardiographic examination should be an essential part of the initial evaluation in such patients. PMID:23518891

    Multiple defibrillations by the automatic implantable cardioverter/defibrillator (AICD) have been reported to result in localized epicardial damage. No data exist, however, regarding whether this damage can be detected in the clinical setting or whether it interferes with the detection of true myocardial infarction. Forty-nine patients who received defibrillations by patch electrodes were studied prospectively. We attempted to document the presence of myocardial injury with the following three commonly used modalities for the detection of myocardial infarction: serial electrocardiographic changes, serial creatine phosphokinase (CPK) and CPK-MB release, and technetium 99m pyrophosphate scanning. Fifteen patients received defibrillations by AICD patches at the time of AICD generator replacement. Nine patients received defibrillations at the time of new AICD lead placement. The average total energy delivered was 85 +/- 29 J. None of these patients had detectable myocardial injury. Ten patients had defibrillations by the AICD patches at the time of bypass operation. One patient in this group developed acute myocardial infarction in the inferior wall after posterior descending coronary bypass operation, as detected by electrocardiogram, 99mTc pyrophosphate scanning, and CPK-MB analysis. Fifteen patients were evaluated for spontaneous AICD discharges. Thirteen had a maximum of five consecutive shocks, and cumulative energy delivered was not greater than 330 J. None of these patients had detectable injury. Two patients had CPK-MB release of 15.3% and 7.5%, respectively. One of these patients had a positive 99mTc pyrophosphate scan. These two patients received 12 and 17 rapid and consecutive AICD discharges, respectively, with cumulative delivered energy of 360 and 510 J, respectively.

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

    Science.gov (United States)

    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.

    Some methodological aspects are discussed of the investigation of acute infarct myocarditis (AIM) in relation to weather fronts. Results of a new method of analysis are given. Data were analysed from about the hour of the onset of symptoms, and led to the diagnosis of AIM either immediately or within a few hours or days (3019 cases observed over 4.5 years during 1982 1986 in Plzen, Czechoslovakia). Weather classification was based on three factors (the type of the foregoing front, the type of the subsequent front, the time section of the time interval demarcated by the passage of the surfaces of the fronts). AIM occurrence increased in particular types of weather fronts: (i) by 30% during 7 12 h after a warm front, if the time span between fronts exceeded 24 h; (ii) by 10% in time at least 36 h distant from the foregoing cold or occlusion front and from the succeeding warm or occlusion front; (iii) by 20% during 0 2 h before the passage of the front, provided the foregoing front was not warm and the interval between fronts exceeded 5 h. AIM occurrence decreased by 15% 20% for time span between fronts > 24 h at times 6 11, 6 23 and 6 35 h before a coming warm or occlusion front (for interfrontal intervals 25 48, 49 72 and possibly > 72 h), and also at 12 23 and possibly 12 35 h before a cold front (for intervals 49 72 and possibly > 72 h), if the foregoing front was cold or an occlusion front.

  15. EVALUATION OF CORONARY RISK FACTORS IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION

    Directory of Open Access Journals (Sweden)

    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

    2001-01-01

    @@Following an acute myocardial infarction (AMI), patients have an increased risk of stroke. Estimates of risk are mainly derived from AMI treatment trials or secondary prevention studies. The reported incidence of stroke in Caucasians in the early phase after AMI ranged from 0.5% to 2.5%.1-3 Similar assessment of risk in the Chinese population is lacking. As thrombolytic therapy becomes standard treatment for AMI, there is concern that there may be an increase in haemorrhagic stroke complicating AMI treatment, especially since haemorrhagic stroke is more common in Asian populations.

    The time period from symptom onset to hospital admission is of outstanding importance for the prognosis of a patient with an acute myocardial infarction. He is threatened by sudden cardiac death triggered by ventricular fibrillation on the one hand and on the other hand this period offers the chance for a timely decision on the optimal reperfusion strategy. A broad spectrum of therapeutic opportunities regarding thrombolysis, antiplatelets and anticoagulation has been proven to be effective in large randomised trials and registries. These results should influence the individual decision on reperfusion treatment as well as the patient's conditions, time lines, logistics and local resources. PMID:18629465

    The aggregation of platelets on the plaque rupture site on the coronary artery is reported to cause both acute coronary syndromes (ACS) and acute myocardial infarction (AMI). While the inhibition of platelet aggregation by acetyl salicylic acid was reported to produce beneficial effects in ACS, it failed to do in AMI. The concentration of a stress induced protein (dermcidin isoform-2) was much higher in AMI than that in ACS. Incubation of normal platelet rich plasma (PRP) with dermcidin showe...

    The aim of the current study was to confirm the effect and elucidate the mechanism of bone marrow mesenchymal stem cells (BMSCs) in acute myocardial infarction (AMI). AMI was induced in mini‑swine by ligating the left anterior descending coronary artery, and BMSCs (1x107) were injected via a sterile microinjection into the ischemic area. Six months postoperatively, electrocardiograph‑gated single photon emission computed tomography revealed that the myocardial filling defect was reduced and the left ventricular ejection fraction was improved in the BMSC group compared with the control group (P<0.05). Histopathological examination indicated that, in the BMSC treatment group, the percentage of survived myocardial tissue and the vessel density were increased, and the percentage of apoptosis was decreased compared with controls (P<0.05). Reverse transcription‑polymerase chain reaction results indicated that the expression levels of multiple inflammatory factors were significantly upregulated in the BMSC group compared with levels in the control group (P<0.05). In conclusion, the present study demonstrated that BMSC injection significantly improved cardiac function and reduced infarct size in six months, indicating that this method may be valuable for future study in clinical trials.

    Full Text Available Acute myocardial infarction is one of the important reasons of death and unhealthiness in the world. The present study was undertaken to investigate the changes in serum lipids and lipoproteins in patients with acute myocardial infarction. The levels of lipid profile were significantly changed in the acute myocardial infarction patients. Acute myocardial infarction patients had significantly higher levels of total cholesterol, LDL-cholesterol, TG, Lipoprotein and lower level of HDL-cholesterol, as compared to the control subjects. We found a significant association of lipid profiles with acute myocardial infarction. Reduced serum HDL-cholesterol and increased Serum LDL, Serum TG, Lipoprotein (a, in our study subjects may be the effective reasonable lipid disorders in AMI patients.

    It has been found that in 15% of acute myocardial infarction patients' platelets generate reactive oxygen species that can be detected with luminol-enhanced chemiluminescence of platelet-rich plasma within 8-10 days after acute myocardial infarction. This increase in generate reactive oxygen species production coincides with the emergence of CD45(+) platelets. The ability of platelets to carry surface leukocyte antigen implies their participation in exchange of specific proteins in the course of acute myocardial infarction. Future studies of CD45(+) platelets in peripheral blood of acute myocardial infarction patients in association with generate reactive oxygen species production may provide a new insight into the complex mechanisms of cell-cell interactions associated with acute myocardial infarction.

  12. Evaluation of the sickness rate for acute myocardial infarction

    International Nuclear Information System (INIS)

    Cardiovascular diseases seem to be the main cause of people's death in industrial developed countries. That is why the active study of factors and conditions affecting the sickness and death rate for this group of diseases is being continued at present. Apart from the well-known risk factors, there is a group of technogenic factors the contribution of which to genesis of the examined group of diseases is not clear enough and requires a detailed study. One of such factors appears to be ionizing radiaiton, especially in case of a prolonged effect with the so-called small doses. The sickness rate due to acute myocardial infarction (AMI) in the period 1999-2001 has been studied in the closed population ZATO Seversk. To conduct examinations there was created the towns AMI register to be a structural component of the regional medico-dosimetric register (RMDR) of the Siberian Group of Chemical Enterprises (SGCE) personnel and population of ZATO Seversk. Information on coronary disasters among adult population above 20 is being collected according to the program AMI Register created by WHO in 1968 with our additional results of modern methods of examining patients with ischemic heart disease and prospective observation. The analysis of data obtained testifies to the tendency towards the sickness rate increase in the period under study both among residents of the town (2,011-2,014-2,238 per 1000 people in 1999, 2000 and 2001, respectively) and among SGCE workers (4,354-4,572-5,006 per 1000) that corresponds to general tendencies of AMI sickness rate on the territory of Russian Federation. it is noted that in the group of workers at the main production the AMI sickness rate exceeds similar indices by the plant as a whole (6,205-7, 176-6,518 per 1000). Great prevalence of this AMI form among workers of a large industrial enterprise can be conditioned by a predominance of male contingent high emotional mental load (shift work on complex technological equipment with

  13. Radioimmunoassay of human cardiac tropomyosin in acute myocardial infarction

    International Nuclear Information System (INIS)

    Tropomyosin was prepared from fresh human myocardium and antisera raised in rabbits. A sensitive radioimmunoassay was developed for the detection of human cardiac 125I-labelled tropomyosin in human sera down to levels of 1 ng/ml. Values for human cardiac tropomyosin in normal patients ranged from less than 1 to 3 ng/ml. In 18 patients with acute myocardial infarction all had elevated tropomyosin levels ranging from 41 to above 200 ng/ml with a mean peak level of 101 ng/ml. In this study there were no false positive or false negative results. In the initial stages of infarction the time course of appearance and peak levels of cardiac tropomyosin, total creatine kinase and creatine kinase MB isoenzyme were similar. Although total creatine kinase and creatine kinase MB isoenzyme levels were normal after 72 h in patients with single, uncomplicated infarction, cardiac tropomyosin levels were still significantly elevated above normal after this time, being 30-60% of peak values. Radioimmunoassay of human cardiac tropomyosin may prove useful in the diagnosis and in the management of patients with acute myocardial infarction, particularly in the long-term postinfarction period.

  14. The effects of different remedies on acute myocardial infarction

    International Nuclear Information System (INIS)

    Objective: To investigate the different treatment effects of intravenous thrombolysis vs primary coronary angioplasty and interhospital transfer for primary coronary angioplasty in acute myocardial infarction within 12 hours after onset. Methods: During January 2004 to December 2005, 63 consecutive patients with acute myocardial infarction admitted directly for primary PCI and 25 patients transferred from other hospitals for primary. PCI were compared with 32 patients treated with intravenous thrombolysis. Each patients arrived at hospital within 12 h from chest pain onset. T-test and Chi-square test were used to analyze the rate of mortality, re-infarction, heart failure in-hospital and 1-year latter. Results: Among the 3 groups, for group of intravenous thrombolysis, time interval from arriving to having reflow was the shortest (1.1 ± 0.2 h vs 2.3 ± 1.0 h vs 2.1 ± 1.1 h, P < 0.01), the mortalities in hospital (6.3% vs 3.2% vs 4.0%) and 1-year follow up (12.5% vs 4.8% vs 8.0%)were highest in spite of no statistic difference. After 1 year, the rate of reinfarction in intravenous thrombolysis group is higher than that in PCI group (18.8% vs 4.5%, P < 0.05). Conclusions: The key point of AMI remedy is to open the criminal vessel as fast as possible. Interhospital transfer for PCI is feasible and safe. (authors)

    Full Text Available Background: Conventional risk factors for coronary artery disease and myocardial infarction do not explain all of the clinical and epidemiological features of the disease. Periodontal disease is a common bacterial and destructive disorder of oral tissues. Many studies demonstrate close association between chronic periodontitis and development of generalized inflammation, vascular endothelial injury, and atherosclesis. Periodontal disease has been convincingly emerging as an important independent risk factor for ischemic heart disease. A case - control study was carried out to assess the prevalence of periodontitis in patients with Acute myocardial Infarction (AMI and evaluate the possible relationship between AMI and chronic periodontitis. Patients and Methods: A number of 160 patients, aged 35 to 70 years old, enrolled in the study. Eighty patients (43 men, 37 women were examined four days after hospitalization due to AMI. Control group consisted of 80 persons (38 men, 42 women with normal coronary angiography. The following periodontal parameters were examined: Plaque index (PI, gingiral index (GI, bleeding on probing (BOP, probing depth (PD, clinical attachment loss (CAL and number of sites with CAL.Results: The case, compared to control showed significantly worse results for some periodontal variables studied: The mean of PD and PD > 3 mm, CAL, and number of sites with CAL, had worse results compared to control despite similar oral hygiene and frequency of brushing. The confounding factors for the present study were found to be hypertension and diabetes. Conclusion: The association between periodontitis and acute myocardial infarction was significant after adjusting for conventional risk factors for AMI.

    The National Registry of Myocardial Infarction 2 (NRMI-2) provides a unique opportunity to evaluate the practice patterns among participating cardiology and emergency medicine departments involved in the care of patients with acute myocardial infarction. The data from NRMI-2 suggest that almost 1/3 of all non-transfer-in and non-transfer-out patients are eligible for reperfusion therapy. Furthermore, of those patients who are clearly eligible for reperfusion therapy, 24% are not given this proven therapy. Specifically, women, the elderly, patients without chest pain on presentation, and those patients at highest risk for in-hospital mortality were least likely to be treated with reperfusion therapy. The reason for underuse of reperfusion therapy may in part reflect a concern for adverse bleeding events associated with the use of thrombolytic therapy. The data from NRMI-2 also suggest that patients with contraindications to thrombolysis may be very appropriate for primary angioplasty. Realizing the full potential benefits of reperfusion therapy in terms of reduced cardiovascular morbidity and mortality will require that clinical practice patterns be aligned more closely with the recommended national guidelines, which are based on extensive clinical trial data that show the benefit of reperfusion therapy in a wide range of patients with acute myocardial infarction. By using observational databases, such as the NRMI-2, which describe how clinical care is administered in nonclinical trial settings, we can continually monitor our progress and initiate changes to ensure that patients are given access to the many therapies that have been shown to improve their quality of life and survival.

  20. Role of myocardial perfusion imaging in acute coronary syndrome

    International Nuclear Information System (INIS)

    Full text: In the cardiac emergency department, a number of patients present with acute chest pain. In case of non diagnostic ECG and enzymes, accurately categorizing the patient in high and low probability is difficult. Aim of study was to evaluate the role of resting myocardial perfusion imaging (MPI) in patients with acute coronary syndrome (ACS) and then to compare the results with subsequent stress imaging. Material and Methods. A total of 34 patients were selected for the study, which were divided into three groups on the basis of respective probabilities of having ACS. This probability was decided on the basis of nature of chest pain, ECG findings, enzymes levels, and age and sex. Arbitrary score was given to patient's condition. This score ranged from 1 to 14. Patients with score between 1-6 were assigned low probability, from 7-10 were assigned intermediate probability and patients having score greater than 11 were placed in high probability groups. Patients in the low and intermediate probability groups were injected with Tc99m- MIBI within 6 hours of onset of chest pain and were undergone resting myocardial perfusion imaging (MPI) 3 to five hours after injection.. Imaging in high probability group was performed at discharge. Four weeks after the acute event all the patients underwent stress myocardial perfusion imaging. Results: All patients (100%) with low probability of ACS (n=10) showed negative resting scans. On stress MPI two patients (20%) showed new defects. Patient with high probability of ACS (n=12), all were positive 100% on resting MPI. On stress MPI, three showed (25%) no change from rest MPI, while nine patients (75%) showed augmentation of defects and four out of these nine patients (33%) also showed new perfusion defects. Patients with intermediate probability of ACS (n=12), three showed positive rest MPI (25%). On stress MPI out of these three cases, one showed (8%) no change from rest MPI and two showed (17%) augmentation of defect shown

    Full Text Available      Carbon monoxide (CO is a toxic gas produced by the incomplete combustion of carbon-containing compounds. Exposure to high concentrations of CO can be letha and is the most common cause of death from poisoning worldwide. Cardiac manifestations after exposure to CO, including myocardial ischemia, heart failure, and arrhythmias, have been reported. A 28-year-old a patient was admitted to our emergency department with altered consciousness as a consequence of acute domestic exposure to CO from a stove. His carboxyhemoglobin level was 39%. The oxygen treatment was started promptly, and therapeutic red cell exchange was performed. An electrocardiogram revealed supraventricular tachycardia (SVT, and an echocardiographic examination demonstrated normal cardiac functions. To the best of our knowledge, this study is the second to report a case of SVT attack due to acute CO intoxication. This paper discusses the management of this complication in patients poisoned with CO.

    2002-01-01

    Full Text Available OBJECTIVE: To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS: We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups according to the presence or absence of angina prior to acute myocardial infarction. We assessed the presence of angina preceding acute myocardial infarction and risk factors, such as age >55 years, male sex, smoking, systemic arterial hypertension, lipid profile, diabetes mellitus, obesity, sedentary lifestyle, and familial history of ischemic heart disease. On coronary angiography, the severity of coronary heart disease and presence of left ventricular hypertrophy were assessed. RESULTS: Of the 104 patients studied, 72.1% were males, 90.4% were white, 73.1% were older than 55 years, and 53.8% were hypertensive. Acute myocardial infarction was the first manifestation of ischemic heart disease in 49% of the patients. The associated risk factors were systemic arterial hypertension (RR=0.19; 95% CI=0.06-0.59; P=0.04 and left ventricular hypertrophy (RR=0.27; 95% CI=0,.8-0.88; P=0.03. The remaining risk factors were not statistically significant. CONCLUSION: Prevalence of acute myocardial infarction as the first manifestation of ischemic heart disease is high, approximately 50%. Hypertensive individuals more frequently have symptoms preceding acute myocardial infarction, probably due to ventricular hypertrophy associated with high blood pressure levels.

    Full Text Available Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI could be used for assessing sheep myocardium following an acute myocardial infarction (MI and response to intervention. Method: 18 sheep enrolled in a pilot study to evaluate [99mTc]-sestamibi MPI at baseline, post-MI and after therapy. Modifications to the standard MPI protocols were developed. All data was reconstructed with OSEM using CT-derived attenuation and scatter correction. Standard analyses were performed and inter-observer agreement were measured using Kappa (. Power determined the sample sizes needed to show statistically significant changes due to intervention. Results: Ten sheep completed the full protocol. Data processed were performed using pre-existing hardware and software used in human MPI scanning. No improvement in perfusion was seen in the control group, however improvements of 15% - 35% were seen after intra-myocardial stem cell administration. Inter-observer agreement was excellent (К=0.89. Using a target power of 0.9, 28 sheep were required to detect a 10-12% change in perfusion. Conclusions: Study demonstrates the suitability of large animal models for imaging with standard MPI protocols and it’s feasibility with a manageable number of animals. These protocols could be translated into humans to study the efficacy of stem cell therapy in heart regeneration and repair.

    Biomedical applications of MOEMS are limited only by the mankind imagination. Precision measurements on minute amounts of biological material could be performed by optical means with a remarkable accuracy. Although available in medical laboratories for general purposes, such analyzers are making their way directly to the users in the form of dedicated equipment. Such an example is a test kit to detect the existence of cardiac enzymes in the blood stream. Apart from the direct users, the medical personnel will make use of such tools given the practicality of the kit. In a large proportion of patients admitted to the hospital suspected of Acute Myocardial Infarction (AMI), the symptoms and electrocardiographic changes are inconclusive. This necessitates the use of biochemical markers of myocardial damage for correct exclusion or conformation of AMI. In this study the concept of MOEMS is applied for the detection of enzyme reaction, in which glass spectrums are scanned optically when enzyme molecules adsorb on their surface. This paper presents the optical behavior of glass spectrums under Horseradish Peroxide (HRP) enzyme reaction. The reported experimental results provide valuable information that will be useful in the development of biosensors for enzymatic detection. This paper also reports the dynamic behavior of different glass spectrums.

    2014-01-01

    Full Text Available Immune thrombocytopenic purpura (ITP, also known as idiopathic thrombocytopenic purpura, is an acquired immune-mediated disease of adults and children characterized by a transient or persistent decrease of platelets and, depending upon the degree of thrombocytopenia, an increased risk of bleeding. The use of standard treatments for acute myocardial infarction (AMI, such as antiplatelet agents and anticoagulants, pose serious problems in patients with ITP due to the potential higher risk of bleeding complications. There are no current guidelines available for management of ITP patients with AMI. In this brief review of the limited available literature, we discuss the proposed pathophysiological link between ITP and arterial thrombosis and the challenging medical and interventional treatment of these patients.

    Raman spectroscopy is a rapidly non-invasive technique with great potential for biomedical research. The aim of this study was to evaluate the feasibility of using Raman spectroscopy of human saliva for acute myocardial infarction (AMI) detection. Raman spectroscopy measurements were performed on two groups of saliva samples: one group from patients (n=30) with confirmed AMI and the other group from healthy controls (n=31). The diagnostic performance for differentiating AMI saliva from normal saliva was evaluated by multivariate statistical analysis. The combination of principal component analysis (PCA) and linear discriminate analysis (LDA) of the measured Raman spectra separated the spectral features of the two groups into two distinct clusters with little overlaps, rendering the sensitivity of 80.0% and specificity of 80.6%. The results from this exploratory study demonstrated that Raman spectroscopy of human saliva can serve as a potentially clinical tool for rapid AMI detection and screening.

    2012-02-01

    Acute myocardial infarction (AMI) in pregnancy is a very rare occurrence. However, statistics indicate high mortality rates, with a maternal death rate at 20-37%. Nursing and medical care of AMI in pregnancy is a very complex issue. Risk factors such as stress, smoking, obesity, high cholesterol and family history of heart disease may increase the risk of AMI in pregnancy. There are a variety of challenges for the nurse caring for this patient, as the presenting signs and symptoms of AMI in pregnancy can mimic regular pregnancy symptoms and therefore may be misdiagnosed. There is limited nursing literature on this topic to guide and educate nurses. Recommendations need to be implemented across multiple nursing settings. There is a need for both national and international guidelines on care of this type of patient. There is also a need for policies to be in place and links within the hospital setting and the community.

    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.

  15. Differentiation of acute myocardial infarction from chronic myocardial scar with MRI

    International Nuclear Information System (INIS)

    The coherent steady-state free precession (SSFP) pulse sequence is increasingly being used in cine imaging for evaluating the cardiac function. Compared to the spoiled gradient echo MRI, which has usually been performed for cardiac cine imaging, the SSFP imaging sequence provides a higher signal-to- noise ratio (SNR) by recycling the residual transverse magnetization, and there is less of an inflow effect by using a very short repetition time. A few studies have recently reported that contrast-enhanced (CE) cine-SSFP imaging could be used for estimating the viability of infarcted myocardium with or without the simultaneous evaluation of the ventricular function. Since the contrast of the SSFP sequence imaging is based on the ratio of T2 to T1, T1-shortening contrast-enhancement is shown as hyperenhancement, which is similar to that in the delayed-enhanced T1-imaging. In this issue of the Korean Journal of Radiology, Kim et al. have reported that the CE-cine-SSFP sequence could be used for differentiating the acutely infarcted myocardium from chronic myocardial scar with a sensitivity of 95.8%. This was a new approach for evaluating the age of myocardial infarction (MI) by using MRI

    2010-02-01

    Full Text Available Our study evaluates the long-term effect of microalbuminuria on mortality among patients with acute myocardial infarction. We followed 151 patients from 1996 to 2007 to investigate if microalbuminuria is a risk factor in coronary heart disease. All patients admitted with acute myocardial infarction in 1996 were included. At baseline, we recorded urinary albumin/creatinine concentration ratio, body mass index, blood pressure, left ventricle ejection fraction by echocardiography, smoking status, medication, diabetes, age, and gender. Deaths were traced in 2007 by means of the Danish Personal Identification Register. Microalbuminuria, defined as a urinary albumin/creatinine concentration ratio above 0.65 mg/mmoL, occurred in 50% of the patients and was associated with increased all-cause mortality. Thus, 68% of the patients with microalbuminuria versus 48% of the patients without microalbuminuria had died during the 10 years of follow-up (P=0.04. The crude hazard ratio for death associated with microalbuminuria was 1.78 (CI: 1.18-2.68 (P=0.006, whereas the gender- and age-adjusted hazard ratio was 1.71 (CI: 1.03-2.83 (P=0.04. We concluded that microalbuminuria in hospitalized patients with acute myocardial infarction is prognostic for increased long-term mortality. We recommend measurement of microalbuminuria to be included as a baseline risk factor in patients with acute myocardial infarction and in future trials in patients with cor-onary heart disease.

    Full Text Available The aim of this study was to clarify the prevalence of coronary risk factors in order to characterize the prognostic factors in elderly patients and to also identify any factors beneficial for the prevention of further cardiac events and death. We studied 888 patients with ST-elevation acute myocardial infarction who were admitted within 48h of symptom onset. The patients were divided into 3 groups according to age for comparison of variables:a younger group (n=99 aged<50, a middle-aged group (n=435>51 years but<70 years and an elderly group (n=354 aged>71 years. The elderly group had higher rates of female gender, pulmonary congestion, in-hospital mortality, and atrial fibrillation and a higher plasma concentration of high-sensitivity CRP (hs-CRP (p<0.05. Hypertension, diabetes mellitus, and dyslipidemia were more common in the middle-aged group (p<0.05. The prevalence of smokers and the plasma level of total cholesterol, LDL-cholesterol and triglycerides were lower in the elderly group (p<0.05. The grade of collateral circulation was highest in the elderly group, but the success rate of reperfusion therapy was lowest. Multiple regression analysis showed that age, pulmonary congestion, CKD and hs-CRP were predictors of in-hospital mortality.This investigation indicated that elderly patients with acute myocardial infarction have different clinical characteristics than younger patients. A specific algorithm might be needed in elderly patients, and could use hs-CRP, eGFR and atrial fibrillation as factors.

  19. Frequency of dyslipidaemia in young patients with acute myocardial infarction

    International Nuclear Information System (INIS)

    Objective: To study the frequency of dyslipidaemia in young patients aged between 20-40 years, with Acute Myocardial Infarction in our population. Study design: Descriptive study Place and duration of Study: Coronary Care Unit (CCU) of Armed Forces Institute of Cardiology (AFIC) National Institute of Heart Diseases (NIHD), Rawalpindi from December 2008 to May 2009. Subjects and Methods: One hundred patients of acute myocardial infarction (AMI) fulfilling the World Health Organization (WHO) diagnostic criteria of AMI, having ages between 20-40 years, were included in the study after full informed consent using non-probability consecutive sampling. Blood samples for serum lipid profile were taken after 12 hours fasting (within 24 hours of presentation), and analyzed in laboratory of AFIC. Individual patients' results were compiled with respect to age, gender, serum total cholesterol, serum triglycerides, serum low density lipoprotein (LDL) cholesterol, serum very low density lipoprotein (VLDL) cholesterol and serum high density lipoprotein (HDL) cholesterol. The data was entered in SPSS (version 11.0) and analyzed. Results: Of the 100 patients with AMI, 47 were found to have dyslipidaernia. Hypertriglyceridaernia was the most common lipid abnormality as it was found in 32 (68.1 %) patients; followed by raised serum VLDL, hypercholesterolemia, raised serum LDL and low serum HDL found in 25 (53.2%), 16 (34.0%), 4 (8.5%) and 2 (4.3%) patients respectively. Out of 47 patients with dyslipidaemia, 28 (59.6%) had more than one lipid abnormality. Conclusion: Frequency of dyslipidaemia in young patients with AMI in our population is high. (author)

  1. X-ray characteristics of heart failure in patients with acute myocardial infarction

    International Nuclear Information System (INIS)

    Results of chest biomedical radiography in 250 men aged 22-69 years who had acute myocardial infarction were evaluated. Data were compared with the results of ECG, echocardiography, Judkins coronarography, and left ventriculography. X-ray signs of pulmonary venous hypertension in acute myocardial infarction, even not followed by cardiomegalia suggest lower left ventricular myocardial contractility. In this connection, the significance of follow-up X-ray monitoring becomes higher. In 25% of the young patients (aged 22-40 years) with prior acute myocardial infarction, the dimensions of the heart may be in the normal ranges even in the presence of X-ray signs of venous congestion. If there are no signs of mitral regurgitation in patients with ischremic heart disease, the enlarged left atrium may be regarded as an indirect X-ray sign of reduced left ventricular contractility.

    Background While sleep apnea (SA) might be a modifiable cardiovascular risk factor, recent data suggest that SA is severely underdiagnosed in patients after acute myocardial infarction (MI). There is limited evidence about day-night variation of onset of MI on dependence of having SA. We therefore investigated the prevalence of SA and examined the day-night variation of onset of MI in acute MI patients. Methods We prospectively studied 782 consecutive patients admitted to the hospital with the diagnosis of acute MI. All subjects underwent sleep evaluations using a portable device after at least 48 hours post-admission. Using the apnea-hypopnea index (AHI), groups were defined as patients without SA (<5 events/hour), mild SA (5–15 events/hour), moderate SA (15–30 events/hour), and severe SA (≥30 events/hour). Results Almost all patients (98%) underwent urgent coronary angiography and 91% of patients underwent primary PCI. Using a threshold of AHI ≥ 5 events/hour, SA was present in 65.7% of patients after acute MI. Mild SA was present in 32.6%, moderate in 20.4% and severe in 12.7%. The day-night variation in the onset of MI in all groups of SA patients was similar to that observed in non-SA patients. From 6AM–12PM, the frequency of MI was higher in both SA and non-SA patients, as compared to the interval from 12AM–6AM (all p<0.05). Conclusion There is a high prevalence of SA in patients presenting with acute MI. Peak time of MI onset in SA patients was between 6AM–noon, similar to that in the general population. Whether diagnosis and treatment of SA after MI will significantly improve outcomes in these patients remains to be determined. PMID:25064202

  4. Decreased myocardial blood volume is a cause of reduced myocardial blood flow reserve in hypertrophic cardiomyopathy

    International Nuclear Information System (INIS)

    The purposes of this study are to know whether myocardial blood volume (MBV) is decreased in the left ventricular myocardium of patients with hypertrophic cardiomyopathy (HCM), and to elucidate which of the decreased MBV or of the reduced rate (mean transit rate of the blood) of myocardial blood flow (MBF), is the cause of the reduced MBF at reactive hyperemia. Subjects were 22 non-obstructive HCM patients (M16/F6, mean age 54 y) exhibiting asymmetric ventricular septum hypertrophy in echocardiography (EC) and 9 male age-matched healthy volunteers. The machine used for EC was Sonos 5500 (Philips Medical Systems) and myocardial contrast EC (MCE) was conducted also with the machine and S3 probe with 1.3/2.6 MHz to get harmonic power Doppler image. The contrast medium was Levovist (Schering AG), which was intravenously infused continuously during EC, and adenosine 5'-triphosphate (ATP) was similarly given to induce the reactive hyperemia. MCE images were processed by the software VoluMap-445 (YD LTD) for calculating MBV (%; mL/100 mL). For obtaining MBF (mL/min/g), positron emission tomography (PET) was done with the machine Siemens/CTI ECAT EXACT HR+Scanner, using 15O-water prepared in Sumitomo cyclotron CYPRIS-HM18, in 13 patients and all volunteers. The mean transit rate was calculated by (MBF/MBV) x 1.67/sec. It was found that MBV was decreased relatedly with the local wall thickness of HCM patients' left ventricular myocardium and MBF was reduced dependently on the decreased MBV at the reactive hyperemia.

    Full Text Available Among all causes of preventable deaths, smoking is responsible for the greatest number of deaths worldwide and predisposes to fatal, noncommunicable diseases, especially cardiovascular diseases. Lifestyle changes are effective in the treatment of patients with smoking-related diseases and assist in the prevention of premature mortality. Our objective was to investigate the available scientific evidence regarding the psychological distress related to smoking cessation in patients who have had acute myocardial infarction. To that end, we conducted an integrative review of the literature in order to summarize relevant studies on this topic. The selected databases were Scopus, PubMed Central, Institute for Scientific Information Web of Science (Core Collection, ScienceDirect, EMBASE, SciELO, LILACS e PsycINFO. On the basis of the inclusion and exclusion criteria adopted for this study, 14 articles were selected for analysis. Those studies showed that the prevalence of psychological distress is higher among smokers than among nonsmokers, and distress-related symptoms are much more common in smokers with acute myocardial infarction than in those without. Smoking cessation depends on the active participation of the smoker, whose major motivation is the underlying disease. Most studies have shown that there is a need to create treatment subgroups as a means of improving the treatment provided. This review article expands the knowledge regarding smoking cessation and shows the need to invest in future research that investigates subgroups of smokers diagnosed with the major smoking-related comorbidities, such as acute myocardial infarction, in order to develop specific interventions and psychological support strategies.

    The present-day optimal treatment of patients with acute myocardial infarction (AMI) is reviewed. The prehospital phase should be as brief as possible. Emergency observation and treatment in hospital should be initiated without delay. Schematic stages for mobilization have been discarded and free mobilization is recommended. Routine acute intervention with thrombolysis is recommended for patients in whom symptoms have been present for 6-12 hours and treatment with Aspirin is recommended. Beta-blocking agents are recommended for patients with increased risk after discharge. Treatment of ventricular and supraventricular arrhythmias, block and cardiac failure are reviewed in detail. Patients without complications should be monitored for three to five days and may be discharged after seven to ten days. Exercise ECG should be carried out at discharge to assess the working capacity, ischaemia and subjective reaction. The importance of good patient information is emphasized. Cessation of smoking, control of lipids and blood pressure are important as secondary interventions. As far as possible, outpatient control should be offered after discharge. The criteria for referral to specialized cardiological departments are established both for emergency and elective referral. Patients under the age of 70 years with high risk for repeated AMI or death after discharge (with residual ischaemia) should possibly be referred for coronary arteriography. PMID:2567543

    2016-01-01

    Acute mitral regurgitation (MR) is a frequent complication of acute myocardial infarction, with a variable presentation depending on the severity of MR and the integrity of the subvalvular apparatus. While most cases are asymptomatic or have mild dyspnea, rupture of chordae tendinea or papillary muscles are catastrophic complications that may rapidly lead to cardiogenic shock and death. Despite the presence of pulmonary edema and/or cardiogrenic shock, the murmur of acute MR is usually subtle due to rapid equalization of left atrial and left ventricular pressure gradient, and therefore misleading. Echocardiog-raphy is the definite diagnostic modality, allowing quantification of the severity of MR and the structural abnormalities within the subvalvular apparatus. Severe MR accompa-nied by rupture of chordae or papillary muscles should be managed with temporary stabilization with medical treatment or with mechanical circulatory support, with sub-sequent surgical intervention to repair or replace the valve.

    Despite early recanalization of an occluded infarct artery, tissue reperfusion remains impaired in more than one-third of the acute myocardial infarction (AMI) patients owing to a process of reperfusion injury. The role of systemic inflammation in triggering this phenomenon is unknown. Proinflammatory factors (hs-CRP, TNF-α) and anti-inflammatory mediators (IL-1 receptor antagonist, IL-10) were measured in 65 patients during the acute phase of a myocardial infarction as well as in 11 healthy ...

    2014-03-01

    Full Text Available Bacteremia- or sepsis-associated myocardial abscess is often an incidental postmortem diagnosis in patients who die of overwhelming septicemia. Myocardial abscess is more rarely the immediate cause of death as a consequence of abscess rupture or the cause of arrhythmia. We report a 66-year-old female who succumbed to sudden cardiac death with a hemodynamically stable methicillin-resistant Staphylococcus aureus (MRSA bacteremia, while in recovery after an accidental thermal burn. Autopsy revealed extensive myocardial abscesses and an abscess in the pineal gland. Myocardial microabscesses should be considered a rare cause of sudden cardiac death in patients with hemodynamically stable MRSA bacteremia.

    International Nuclear Information System (INIS)

    Objective: To analyze the characteristics and in-hospital outcome of patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI) and to evaluate the influence of urgent coronary revascularization on in-hospital mortality. Materials and Methods: All consecutive patients with AMI and CS, admitted at The Aga Khan University Hospital, Karachi Pakistan, during the year 2001 were reviewed. A pre-designed questionnaire was used for data collection. Analysis was done using the SPSS statistical package. Results: Out of 615 patients with AMI, 53 (8.6%) had CS. Mean age was 60.9 plus minus 10.7 years. 62.3% were men, 52.8% were hypertensive and 43.4% were diabetic. Most infarcts were anterior in location (56.6%). Thrombolytic therapy (Streptokinase) was administered to 43.5% of patients with ST segment elevation myocardial infarction. 64.2% required ventilator support while swan ganz was used in 37.7%. Intra-aortic balloon pump was inserted in 39.6%. Ventricular tachycardia was the most common complication (39.6%). Overall in-hospital mortality was 54.7%. CS associated with mechanical complications had 80% in-hospital mortality. In patients without mechanical complications (n=48), in-hospital mortality was significantly lower in the revascularization group (31.6% vs. 65.5%, p-value = 0.021). However, there were significant differences in the baseline characteristics in the two groups because of the selection bias. Conclusion: CS occurring in patients with AMI has an extremely poor prognosis. Patients selected for revascularization strategy has favorable in-hospital outcome. (author)

    Randomized controlled trials that compared primary percutaneous transluminal coronary angioplasty with thrombolysis have shown that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction. Three large myocardial infarction registries - MITI, NRMI-2 and French registry - failed to show an advantage of primary angioplasty compared with thrombolysis. One of the latest trials mentioned in this paper restored the place of primary angioplasty as superior to thrombolysis in acute myocardial infarction. Data of patients treated with primary percutaneous transluminal coronary angioplasty in Clinic of Cardiology of Vilnius University are presented. PMID:15079110

    2016-07-01

    While progress has been made in improving survival following myocardial infarction, this injury remains a major source of mortality and morbidity despite modern reperfusion therapy. While one approach has been to develop therapies to reduce lethal myocardial cell reperfusion injury, this concept has not translated to the clinics, and several recent negative clinical trials raise the question of whether reperfusion injury is important in humans undergoing reperfusion for acute ST segment elevation myocardial infarction. Therapy aimed at reducing myocardial cell death while the myocytes are still ischemic is more likely to further reduce myocardial infarct size. Developing new therapies to further reduce left ventricular remodeling after the acute event is another approach to preserving structure and function of the heart after infarction. Such therapy may include chronic administration of pharmacologic agents and/or therapies developed from the field of regenerative cardiology, including cellular or non-cellular materials such as extracellular matrix. The optimal therapy will be to administer agents that both reduce myocardial infarct size in the acute phase of infarction as well as reduce adverse left ventricular remodeling during the chronic or healing phase of myocardial infarction. Such a dual approach will help optimize the preservation of both cardiac structure and function. PMID:26612091

    Full Text Available Background: Atherosclerosis is a multi-factorial disease involving the interplay of genetic and environmental factors. Studies highlighting the public health importance of risk factors like chronic infections causing acute myocardial infarction (AMI in the Indian context are scarce. This study was undertaken to study the association of socio-demographic and life-style factors with acute myocardial infarction in central India. Materials and Methods: The cases and controls were group-matched for age, gender, and socio-economic status. A blinded research associate administered the study questionnaire. We performed an unconditional multiple logistic regression analysis. Results: The case-control study included 265 cases of AMI and 265 controls. The results of final model of logistic regression analysis for risk factors of AMI included 11 risk factors at α = 0.05. They were waist hip ratio, body mass index, stress at home in last 1 year, hypertension, family history of CHD, past history of gingival sepsis, tobacco smoking, raised total serum cholesterol, Chlamydia pneumoniae, Helicobacter pylori and raised C-reactive protein. Conclusion: The findings confirm the role of conventional risk factors for cardiac disease and highlight need for research into the association between chronic infections with AMI.

This study was designed to determine the effect of primary percutaneous coronary intervention (PCI in patients with CAVB complicating acute inferior STEMI, at a single center.Methods: We enrolled 138 consecutive patients diagnosed with STEMI involving the inferior wall; of these, 27 patients had CAVB. All patients received primary PCI. The clinical characteristics, procedural data, and clinical outcomes were compared in patients with versus without CAVB. Results: Baseline clinical characteristics were similar between patients with and without CAVB. Patients with CAVB were more likely to present with cardiogenic shock, and CAVB was caused primarily by right coronary artery occlusion. Door-to-balloon time was similar between those two groups. After primary PCI, CAVB was reversed in all patients. The peak creatinine phosphokinase level, left ventricular ejection fraction and in-hospital mortality rate were similar between the two groups. After a median follow up of 318 days, major adverse cardiac events did not differ between the groups (8.1% in patients without CAVB; 11.1% in patients with CAVB (P=0.702.Conclusion: We conclude that primary PCI can ameliorate CAVB-complicated acute inferior STEMI, with an acceptable rate of major adverse cardiac events, and suggest that primary PCI should be the preferred reperfusion therapy in patients with CAVB complicating acute inferior myocardial infarction. Keywords: major adverse cardiac events, PCI-capable hospital

    2012-01-01

    Spontaneous coronary artery dissection is a rather rare cause of myocardial infarction, chest pain, and sudden death. Since the condition was first described in 1931, fewer than 200 cases have been reported in the medical literature. There are currently no known direct causes of this condition, although some correlations have been noted. Many patients are women in the peripartum period or of childbearing age, with few or no risk factors for coronary artery disease. Other associations include contraceptive use and connective-tissue disorders, Ehlers-Danlos and Marfan syndromes, and polyarteritis nodosa. Most of the reported dissections have occurred in the left anterior descending coronary artery. Herein, we report the case of a 36-year-old woman who presented at our institution with an acute ST-elevation myocardial infarction secondary to a spontaneous dissection of the right coronary artery. Thrombectomy and stenting resolved the occlusion of the artery, and the patient was discharged from the hospital on medical therapy. We discuss the pathophysiology, presentation, and treatment of this rare and often fatal condition. PMID:22412239

    Full Text Available Abstract Background Despite significant improvements in the treatment of coronary heart disease (CHD, it is still a major cause of mortality and morbidity among the Iranian population. Epidemiological studies have documented that risk factors including smoking and the biochemical profile are responsible for the development of acute myocardial infarction (AMI. Psychological factors have been discussed as potential risk factors for coronary heart disease. Among emotional factors, depression correlates with coronary heart disease, particularly myocardial infarction. Methods This case-control study was conducted on 120 cases (69 males and 51 females of acute myocardial infarction (AMI and 120 controls, with a mean age of 62.48 ± 15.39 years. Cases and controls were matched by age, residence and sex. Results The results revealed that severe depression was independently associated with the risk of AMI (P = 0.025, OR = 2.6, 95% CI 1.1-5.8. The analysis of variables indicated that risk factors for developing depression were unmarried, low levels of polyunsaturated fatty acids (PUFAs, total dietary fiber (TDF and carbohydrates. The levels of these dietary factors were lowest in severely depressed patients compared to those categorised as moderate or mild cases. Furthermore, severely depressed subjects were associated with higher levels of total cholesterol, high systolic blood pressure (SBP and WHR. Age, income, a family history of coronary heart disease, education level, sex, employment and smoking were not associated with severe depression. Conclusion The present study demonstrated that severe depression symptoms are independent risk factors for AMI. Furthermore, severe depression was associated with an unhealthy diet and AMI risk factors.

    Full Text Available Abstract Background Diabetes mellitus and renal dysfunction are prognostic factors after acute myocardial infarction (AMI. However, few studies have assessed the effects of renal insufficiency in association with diabetes in the context of AMI. Here, we investigated the clinical outcomes according to the concomitance of renal dysfunction and diabetes mellitus in patients with AMI. Methods From November 2005 to August 2008, 9905 patients (63 ± 13 years; 70% men with AMI were enrolled in a nationwide prospective Korea Acute Myocardial Infarction Registry (KAMIR and were categorized into 4 groups: Group I (n = 5700 had neither diabetes nor renal insufficiency (glomerular filtration rate [GFR] ≥ 60 ml/min/1.73 m2, Group II (n = 1730 had diabetes but no renal insufficiency, Group III (n = 1431 had no diabetes but renal insufficiency, and Group IV (n = 1044 had both diabetes and renal insufficiency. The primary endpoints were major adverse cardiac events (MACE, including a composite of all cause-of-death, myocardial infarction, target lesion revascularization, and coronary artery bypass graft after 1-year clinical follow-up. Results Primary endpoints occurred in 1804 (18.2% patients. There were significant differences in composite MACE among the 4 groups (Group I, 12.5%; Group II, 15.7%; Group III, 30.5%; Group IV, 36.5%; p p = 0.001; and HR, 2.42; 95% CI, 1.62-3.62; p Conclusions Renal insufficiency, especially in association with diabetes, is associated with the occurrence of composite MACE and indicates poor prognosis in patients with AMI. Categorization of patients with diabetes and/or renal insufficiency provides valuable information for early-risk stratification of AMI patients.

    Full Text Available There is a misconception among our people that opioids may prevent or have ameliorating effects in the occurrence of cardiovascular diseases. In this study we evaluated 556 consecutive male patients hospitalized due to acute myocardial infarction (MI in city of Yazd, from May 2000 to October 2001 and compared the characteristics of opium addicts to non opium users. Prevalence of opium addiction in MI patients was 19% in comparison with 2-2.8% in general population. There were not any differences in prevalence of traditional risk factors between opium users and non-users. Overall, in-hospital mortality was 18.6 percent among opium users and 6.2 percent among non-opium users (unadjusted odd ratio, 1.3; 95% confidence interval, 0.7 to 2.7, P = 0.2. After adjustment for the differences in the baseline features (age and other risk factors, odds ratio increased to 2.2 (95 percent confidence interval, 0.9 to 5.1. It seems that opium addiction may work as a risk factor in cardiovascular disease.

    Heart rate (HR variability has been extensively studied in patients surviving an acute myocardial infarction (AMI. The majority of studies have shown that patients with reduced or abnormal HR variability/turbulence have an increased risk of mortality within few years after an AMI. Various measures of HR dynamics, such as time-domain, spectral, and non-linear measures of HR variability, as well as HR turbulence, have been used in risk stratification of post-AMI patients. The prognostic power of various measures, except of those reflecting rapid R-R interval oscillations, has been almost identical, albeit some non-linear HR variability measures, such as short-term fractal scaling exponent, and HR turbulence, have provided somewhat better prognostic information than the others. Abnormal HR variability predicts both sudden and non-sudden cardiac death after AMI. Because of remodeling of the arrhythmia substrate after AMI, early measurement of HR variability to identify those at high risk should likely be repeated later in order to assess the risk of fatal arrhythmia events. Future randomized trials using HR variability/turbulence as one of the pre-defined inclusion criteria will show whether routine measurement of HR variability/turbulence will become a routine clinical tool for risk stratification of post-AMI patients.

    Full Text Available BACKGROUND: Although experimental studies have demonstrated that reduced glutathione (GSH is involved in cellular protection from deleterious effects of oxygen free radicals in ischaemia and reperfusion, there are controversial data on the correlation between levels of GSH and the ischaemic process. AIM: The present study was planned to evaluate erythrocyte GSH levels in patients with acute myocardial infarction (AMI. SETTING & DESIGN: Erythrocyte GSH levels were determined in 22 patients with AMI and 15 age matched healthy volunteers served as control. MATERIAL & METHODS: Erythrocyte GSH levels were measured by using Bentler in AMI and control patients. Also lipid profile was analyzed enzymatically in these subject. STATISTICS: The values were expressed as means +/- standard deviation (SD and data from patients and controls was compared using student′s ′t′-test. Results and CONCLUSION: GSH levels were significantly decreased in AMI as compared to control (p<0.001. Also, total cholesterol and triglycerides were higher is AMI subjects (p<0.05. These finding suggest that depressed GSH levels may be associated with enhanced protective mechanism to oxidative stress in AMI.

    Objective: To determine the frequency of in-hospital adverse outcomes of acute myocardial infarction in patients with stress hyperglycemia. Methodology: This was a descriptive cross sectional study conducted from August 2010 to January 2011 in Cardiology department, Lady Reading Hospital, Peshawar. Patients of age 25-70 years, of either gender, non-diabetic with acute myocardial infarction with stress hyperglycemia were included. Random blood sugar >144 mg/dl was taken as stress hyperglycemia for patients at presentation of acute myocardial infarction. Patients were monitored for electrical complications such as atrial fibrillation, ventricular tachycardia, ventricular fibrillation and complete heart block and mechanical complications such as cardiac pulmonary edema and cardiogenic shock during hospital stay. The statistical analysis was performed using the statistical package for social sciences (SPSS Ver. 15.0). Results: A total of 341 patients having acute myocardial infarction with stress hyperglycemia were studied. The mean age was 56.35 +- 9.748 (95% CI 57.39 - 55.31). Male were 58.1% (n=198). The frequency of various major in-hospital electrical adverse outcomes of acute myocardial infarction with stress hyperglycemia were atrial fibrillation (AF) 15.8%, ventricular tachycardia (VT) 11.7%, ventricular fibrillation (VF) 10.9% and complete heart block (CHB) 6.7%, while mechanical adverse outcomes were cardiac pulmonary edema (CPE) 7.9% and cardiogenic shock (CS) 11.7%. Conclusion: Stress hyperglycemia has adverse impact on outcomes of patients presenting with acute myocardial infarction. Among electrical and mechanical complications of acute myocardial infarction in patients with stress hyperglycemia, the two most frequent in-hospital adverse outcomes were atrial fibrillation and cardiogenic shock, respectively.

    Full Text Available BACKGROUND: High-sensitivity C-reactive protein predicts cardiovascular events in a wide range of clinical contexts. However, the role of high-sensitivity C-reactive protein as a predictive marker for perioperative acute myocardial infarction during noncardiac surgery is not yet clear. The present study investigated high-sensitivity C-reactive protein levels as predictors of acute myocardial infarction risk in patients undergoing high-risk noncardiac surgery. METHODS: This concurrent cohort study included patients aged >50 years referred for high-risk noncardiac surgery according to American Heart Association/ACC 2002 criteria. Patients with infections were excluded. Electrocardiograms were performed, and biomarkers (Troponin I or T and/or total creatine phosphokinase and the MB fraction (CPK-T/MB were evaluated on the first and fourth days after surgery. Patients were followed until discharge. Baseline high-sensitivity C-reactive protein levels were compared between patients with and without acute myocardial infarction. RESULTS: A total of 101 patients undergoing noncardiac surgery, including 33 vascular procedures (17 aortic and 16 peripheral artery revascularizations, were studied. Sixty of the patients were men, and their mean age was 66 years. Baseline levels of high-sensitivity C-reactive protein were higher in the group with perioperative acute myocardial infarction than in the group with non-acute myocardial infarction patients (mean 48.02 vs. 4.50, p = 0.005. All five acute myocardial infarction cases occurred in vascular surgery patients with high CRP levels. CONCLUSIONS: Patients undergoing high-risk noncardiac surgery, especially vascular surgery, and presenting elevated baseline high-sensitivity C-reactive protein levels are at increased risk for perioperative acute myocardial infarction.

    Full Text Available Abstract Background Myocardial edema is a substantial feature of the inflammatory response in human myocarditis. The relation between myocardial edema and myocardial mass in the course of healing myocarditis has not been systematically investigated. We hypothesised that the resolution of myocardial edema as visualised by T2-weighted cardiovascular magnetic resonance (CMR is associated with a decrease of myocardial mass in steady state free precession (SSFP-cine imaging. Methods 21 patients with acute myocarditis underwent CMR shortly after onset of symptoms and 1 year later. For visualization of edema, a T2-weighted breath-hold black-blood triple-inversion fast spin echo technique was applied and the ratio of signal intensity of myocardium/skeletal muscle was assessed. Left ventricular (LV mass, volumes and function were quantified from biplane cine steady state free precession images. 11 healthy volunteers served as a control group for interstudy reproducibility of LV mass. Results In patients with myocarditis, a significant decrease in LV mass was observed during follow-up compared to the acute phase (156.7 ± 30.6 g vs. 140.3 ± 28.3 g, p In controls, the interstudy difference of LV mass was lower than in patients (5.1 ± 2.9 g vs. 16.3 ± 14.2 g, p = 0.02 resulting in a lower coefficient of variability (2.1 vs 8.9%, p = 0.04. Conclusion Reversible abnormalities in T2-weighted CMR are paralleled by a transient increase in left ventricular mass during the course of myocarditis. Myocardial edema may be a common pathway explaining these findings.

    Full Text Available BACKGROUND: Little is known about the association between financial stress and health care outcomes. Our objective was to examine the association between self-reported financial stress during initial hospitalization and long-term outcomes after acute myocardial infarction (AMI. MATERIALS AND METHODS: We used prospective registry evaluating myocardial infarction: Event and Recovery (PREMIER data, an observational, multicenter US study of AMI patients discharged between January 2003 and June 2004. Primary outcomes were disease-specific and generic health status outcomes at 1 year (symptoms, function, and quality of life (QoL, assessed by the Seattle Angina Questionnaire [SAQ] and Short Form [SF]-12. Secondary outcomes included 1-year rehospitalization and 4-year mortality. Hierarchical regression models accounted for patient socio-demographic, clinical, and quality of care characteristics, and access and barriers to care. RESULTS: Among 2344 AMI patients, 1241 (52.9% reported no financial stress, 735 (31.4% reported low financial stress, and 368 (15.7% reported high financial stress. When comparing individuals reporting low financial stress to no financial stress, there were no significant differences in post-AMI outcomes. In contrast, individuals reporting high financial stress were more likely to have worse physical health (SF-12 PCS mean difference -3.24, 95% Confidence Interval [CI]: -4.82, -1.66, mental health (SF-12 MCS mean difference: -2.44, 95% CI: -3.83, -1.05, disease-specific QoL (SAQ QoL mean difference: -6.99, 95% CI: -9.59, -4.40, and be experiencing angina (SAQ Angina Relative Risk = 1.66, 95%CI: 1.19, 2.32 at 1 year post-AMI. While 1-year readmission rates were increased (Hazard Ratio = 1.50; 95%CI: 1.20, 1.86, 4-year mortality was no different. CONCLUSIONS: High financial stress is common and an important risk factor for worse long-term outcomes post-AMI, independent of access and barriers to care.

    Objective: To assess the myocardial perfusion in patients with acute myocardial infarction (AMI) after delayed percutaneous transluminal coronary angioplasty (PTCA) and intracoronary stent implanting. Methods: Fifty-six patients with AMI were divided into delayed PTCA + stent group (treatment group, n=30) and control group (n=26). The treatment group were received delayed PTCA and coronary artery stents 15-30 d after AMI. The first 99Tcm-MIBI was performed 1-3 d before PTCA + stent (treatment group) and 15-30 d after AMI (control group), and followed by the second (1 month later), and the third (6 months later) 99Tcm-MIBI. Results: One month and six months after the treatment procedure (PTCA + stent), the blood flow deficit degree of myocardial infarction area in treatment group was much improved comparing with that before the procedure (treatment group, P0.05). Conclusions: There is residual myocardial viability in the AMI regions and PTCA + stent implantation keeps more jeopardize myocardium viable. Active therapy after AMI can significantly improve myocardial perfusion

    Background The loss of cardiac myocytes is one of the mechanisms involved in acute myocardial infarction (AMI)-related heart failure. Autophagy is a common biological process in eukaryote cells. The relationship between cardiac myocyte loss and autophagy after AMI is still unclear. Carvedilol, a non-selective α1- and β-receptor blocker, also suppresses cardiac myocyte necrosis and apoptosis induced by ischemia. However, the association between the therapeutic effects of carvedilol and autophagy is still not well understood. The aim of the present study was to establish a rat model of AMI and observe changes in autophagy in different zones of the myocardium and the effects of carvedilol on autophagy in AMI rats.Methods The animals were randomly assigned to a sham group, an AMI group, a chloroquine intervention group and a carvedilol group. The AMI rat model was established by ligating the left anterior descending coronary artery. The hearts were harvested at 40 minutes, 2 hours, 24 hours and 2 weeks after ligation in the AMI group, at 40 minutes in the chloroquine intervention group and at 2 weeks in other groups. Presence of autophagic vacuoles (AV) in the myocytes was observed by electron microscopy. The expression of autophagy-, anti-apoptotic- and apoptotic-related proteins, MAPLC-3, Beclin-1, Bcl-xl and Bax, were detected by immunohistochemical staining and Western blotting. Results Avs were not observed in necrotic regions of the myocardium 40 minutes after ligation of the coronary artery. A large number of Avs were found in the region bordering the infarction. Compared with the infarction region and the normal region, the formation of AV was significantly increased in the region bordering the infarction (P <0.05). The expression of autophagy- and anti-apoptotic-related proteins was significantly increased in the region bordering the infarction. Meanwhile, the expression of apoptotic-related proteins was significantly increased in the infarction region. In

    This study aims to compare and analyze lactate dehydrogenase (LDH), succinic dehydrogenase (SDH) and differences in capillary density level in the model of myocardial damage which caused by rats diabetes. The Wistar rats were divided into 4 groups, including control, diabetic, myocardial infarction and two diseases combined group. Ligate descending branch of left coronary artery on 1/3 position or inject streptozotocin into abdominal cavity to establish two kinds of disease models. After 6 w, obtain the myocardial tissues to do the vascular density analysis of tissue sections which are stained and cell tissue enzyme. Explore change of relevant index and differences among groups. Results indicated that degree of LDH and SDH decrease in two kinds of disease model. Compared with control group, level of myocardial vascular of myocardial injury group is higher, and diabetic group is higher than non diabetic group. Quantitative result of FFA in mitochondrial suspension of single disease group is higher than that of control group and two diseases combined group. Level of FFA and LDH of two diseases combined group is consistent with control group. In conclusion, after myocardial damage, which is caused by diabetes mellitus or myocardial infarction, degree of local vascularization increases, diabetes mellitus is more obvious. After myocardial damage, process of myocardial mitochondrial glycolysis and oxidative phosphorylation has some obstacles. But these two kinds of diseases all have cardiac muscle cell which can keep generated procedure of aerobic and anaerobic energy to instead the normal function of cardiac muscle. PMID:26885216

    @@ The risk of myocardial infarction increases in patients with diabetes mellitus. The incidence of myocardial in-farction is similar in patients with type 2 diabetes without history of myocardial infarction and in non-diabetic pa-tients with history of myocardial infarction. Diabetes mellitus was considered as a coronary disease equivalent by the National Cholesterol Education Program. Strict glycemic control can improve the long-term outcome of both type 1 and type 2 diabetes mellitus. Whatever with diabetic or non-diabetic, strict glycemic control with in-tensive insulin therapy can reduce the mortality of criti-cally ill patients in hospital. After myocardial infarction, there would be a worse outcome for patients with poor glycemic control, whatever in diabetic or non-diabetic patients with stress hyperglycemia.

    Advances in the management of myocardial infarction have resulted in substantial reductions in morbidity and mortality. However, after acute treatment a number of diagnostic and prognostic questions often remain to be answered, whereby cardiac imaging plays an essential role. For example, some patients will sustain early mechanical complications after infarction, while others may develop significant ventricular dysfunction. Furthermore, many individuals harbour a significant burden of residual coronary disease for which clarification of functional ischaemic status and/or viability of the suspected myocardial territory is required. Cardiac magnetic resonance (CMR) imaging is well positioned to fulfil these requirements given its unparalleled capability in evaluating cardiac function, stress ischaemia testing and myocardial tissue characterisation. This review will focus on the utility of CMR in resolving diagnostic uncertainty, evaluating early complications following myocardial infarction, assessing inducible ischaemia, myocardial viability, ventricular remodelling and the emerging role of CMR-derived measures as endpoints in clinical trials.

Angiography showed tight stenosis of the proximal left anterior descending (LAD) and borderline lesion in left circumflex coronary artery (LCX). She underwent percutaneous coronary intervention (PCI) to LAD with good result. Her blood tests showed low vitamin B12, folate and serum iron levels and elevated serum homocysteine level. She was given folic acid and vitamin B12 and her homocysteine levels normalized. This case demonstrates that hyperhomocysteinemia caused by nutritional deficiency of vitamin co factors may lead to MI. Hyperhomocysteinemia should be considered in the evalauation of young people with MI, especially those without conventional risk factors. PMID:25838876

    Objective The coronary anatomic feature and development after thrombolysis in acute myocardial infarction (AMI) were studied.Mehtods 100 patients with AMI received urokinase and strepokinase. 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.

    A 17-year-old girl developed an acute myocardial infarction immediately after being bitten by a viper and four days later she had a cerebrovascular accident. The close clinical and laboratory follow-up of this case suggested that myocardial damage could be attributed to a direct cardiotoxic effect of the venom, while the brain injury that subsequently appeared was probably the result of a disseminated intravascular coagulopathy, possibly in conjunction with vasculitis.

  8. Mechanisms of post-myocardial infarction healing : from acute survival to chronic remodeling

    OpenAIRE

    2009-01-01

    Acute survival and chronic healing after myocardial infarction (MI) depend on a myriad of processes that begin within hours of the injury and can continue in the form of remodeling even years thereafter. The myocardium has very little self-renewal capability, and tissue lost to MI is replaced with a collagenous scar. There are currently no clinical therapies that directly target myocardial healing, due in part to the pleiotropic effects and redundancy of signaling factors released after injur...

    Cauterization of rat myocardium serves as a quick (2 min) inexpensive technique to create an animal model of acute myocardial infarction useful in evaluating radiopharmaceuticals as potential clinical imaging agents. Preliminary evidence indicates that it correlates well with behavior in man. Application of the model led to the discovery, confirmed by later investigators, that chelating agents such as glucoheptonate and polyphosphate show significant uptake in recent myocardial lesions

    Lipoprotein levels are currently recognized as independent risk factors for long-term cardiovascular events after acute myocardial infarction (AMI). During the acute-phase reaction after AMI, previous studies have reported trends of decreased low-density lipoprotein cholesterol (LDL-C), increased triglycerides, and variable high-density lipoprotein cholesterol (HDL-C) levels. However, the association between LDL-C and HDL-C levels and in-hospital mortality has not been well established following AMI. The relationship between lipid levels and in-hospital all-cause mortality in 115,492 patients hospitalized for AMI (July 2002 to December 2006), registered in the National Registry of Myocardial Infarction (NRMI) 4b-5, was evaluated using multivariable-adjusted logistic regression models. Mean LDL-C was 104 ± 38, HDL-C was 41 ± 14, and triglycerides 143 ± 83 mg/dl. Compared with the lowest quartile of LDL-C (NRMI 4b-5 suggest a lipid paradox, with lower LDL-C levels associated with increased risk of in-hospital mortality, contrary to findings outside the acute setting. Consistent with previous analyses, lowest HDL-C levels were associated with increased in-hospital mortality. In conclusion, further explorations of the relationship between very low levels of LDL-C, myocardial necrosis, and subsequent adverse cardiovascular events are warranted. PMID:25727079

    BACKGROUND: Ventricular fibrillation (VF) in the setting of acute ST elevation myocardial infarction (STEMI) is a leading cause of mortality. Although the risk of VF has a genetic component, the underlying genetic factors are largely unknown. Since heart rate and ECG intervals of conduction and repolarization during acute STEMI differ between patients who do and patients who do not develop VF, we investigated whether SNPs known to modulate these ECG indices in the general population also impa...

    We present a young lady who consumed hair dye, which contained paraphenylene diamine (PPD), as a means of deliberate self-harm. This resulted in severe angio-neurotic edema for which she had to be ventilated, and thereafter developed rhabdomyolysis leading to acute kidney injury (AKI). The unusual aspect was that the patient continued to have flaccid quadriparesis and inability to regain kidney function. Renal biopsy performed 10 weeks after the dye consumption revealed severe acute tubular necrosis with myoglobin pigment casts. This suggests that PPD has a long-term effect leading to ongoing myoglobinuria, causing flaccid paralysis to persist and preventing the recovery of AKI. In such instances, timely treatment to prevent AKI in the form alkalinization of urine should be initiated promptly. Secondly, because PPD is a nondialyzable toxin, and its long-term effect necessitates its speedy removal, hemoperfusion might be helpful and is worth considering. PMID:26354573

  7. Estimate of myocardial salvage in late presentation acute myocardial infarction by comparing functional and perfusion abnormalities in predischarge gated SPECT

    International Nuclear Information System (INIS)

    We hypothesized that, because of persistent stunning, the extent of post-treatment functional abnormalities detected using gated single-photon emission computed tomography (SPECT) could be representative of the initial risk area in acute myocardial infarction (AMI) treated by reperfusion therapy. In 48 AMI patients, we acquired two 99mTc-sestamibi gated SPECT studies (at admission with tracer injection before treatment and at discharge 5 to 10 days later). We assessed the myocardial salvage defined by the admission minus predischarge summed rest score, and we compared it with the value obtained by subtracting the extent of perfusion defect from the extent of wall motion or wall thickening abnormalities in predischarge gated SPECT. Myocardial salvage was expressed as salvage index (salvaged myocardium divided by initial risk area). There was a good correlation between summed rest score salvage index and wall motion (Spearman's ρ = 0.754, p 99mTc-sestamibi gated SPECT allows assessing myocardial salvage using only post-treatment data. The salvage index derived using wall thickening as surrogate of admission perfusion defect correlates well with the salvage index measured by comparing pre- and post-treatment perfusion defects.

    Objective: To examine the effect of Yuxingeng fluid (愈心梗液, YXGF) on myocardial energy metabolism in Wistar rats with acute myocardial infarction (AMI) by observing the ultrastructure of mitochondria and the enzyme activities of rat myocardial adenosine triphosphate (ATP), succinate dehydrogenase (SDH), acid phosphatase (ACP), alkaline phosphatase (ALP) and the content of glycogen. Methods: AMI models were established by ligature of left anterior descending coronary artery and then the rats with AMI were randomly divided into 7 groups: namely, blank group, model group, sham-operated group, captopil group, high-dose YXGF group, middle-dose YXGF group and Iow-dose YXGF group. From the next day after modeling, the rats were given YXGF through gastrogavage which lasted for 4 weeks. And then, the ultrastructure of mitochondria was observed by electronic microscope and the enzyme activities of ATP, SDH,ACP, ALP and the content of glycogen were determined. Results: Compared with model group, the other three groups of high-dose YXGF, middle-dose YXGF, Iow-dose YXGF and captopril group could protect the ultrastructure of mitochondria and significantly increase enzyme activities of ATP, SDH, ACP, ALP and the content of glycogen (P<0.01). Conclusion: YXGF can protect mitochondria and increase myocardial enzyme activities and the content of glycogen, which may be one of the mechanisms intervening in the pathological course of the early ventricular remodeling in rats with AMI.

    Full Text Available Introduction. Acute myocardial infarction has negative influence on patient’s quality of life. The objective of the paper was to assess the healthrelated quality of life in the patients one month and twelve months after acute myocardial infarction and to compare it with the healthy controls. Material and Methods. A prospective cohort study involved 160 patients aged from 30 to 79 and 240 healthy controls. The health-related quality of life was assessed with the Serbian version of these questionnaires: Euro- Quol-5-Dimension and EuroQuolVAS. Angina pectoris was ranked according to the classification of Canadian Cardiovascular Society. Multivariate logistic regression analysis was used. Results. The healthy controls had significantly higher average scores in EuroQuolVAS compared with the patients one month after acute myocardial infarction (74.35±9.42 vs 60.50±12.03, p<0.001, as well as twelve months after acute myocardial infarction (74.35±9.42 vs 69.83±12.06, p<0.001. Significantly lower average ranges in EuroQuol-5-Dimension questionnaire and higher quality of life were found twelve months after acute myocardial infarction than one month after acute myocardial infarction (1.41±0.26 vs 1.53±0.26, p<0.001. The average ranges of angina pectoris were significantly lower in all the patients twelve months after acute myocardial infarction compared with the first month (0.78±0.51 vs 0.91±0.44, p<0.001. The multivariate regression analysis confirmed thrombolytic therapy, percutaneous transluminal angioplasty and age to be important factors influencing health-related quality of life. Conclusion. The patients assessed their health condition to be significantly higher twelve months after acute myocardial infarction than one month after it. The health-related quality of life was significantly higher in patients who had undergone the percutaneous intervention than in those who had been treated with the thrombolytic therapy.

    Full Text Available Aim. The case of successful surgical treatment of anterolateral papillary muscle rupture due to acute myocardial infarction with cardiogenic shock, pulmonary edema and acute renal failure. Case report. A 62-year old male from Belgrade with chest pain, hypotension and a new heart murmur refused hospitalization at the Military Medical Academy. On the third day of his illness he was readmitted to MMA as an emergency due to hemoptysis. Examination revealed mitral valve anterolateral papillary muscle rupture. The patient, with signs of cardiogenic shock and acute renal failure, was immediately operated on. The surgery was performed using extracorporeal circulation. An artificial mitral valve was implanted, and myocardial revascularization accomplished with one venous graft of the left anterior descending artery. On the second postoperative day, hemodialysis was carried out due to acute renal failure. On the 28th postoperative day, the patient was discharged from the hospital being hemodynamically stable with normal renal function and balanced anticoagulation. The case is interesting in terms of unrecognized papillary muscle rupture that led to the development of cardiogenic shock, hemoptysis and acute renal failure. Conclusion. Papillary muscle rupture is a fatal complication of acute myocardial infarction. Early recognition and urgent surgical intervention were lifesaving in the case of complete papillary muscle rupture. Surgical treatment, regardless of high risk, is the procedure of choice.

    A surface plasmon resonance (SPR) sensor developed for the rapid, sensitive and specific detection of cardiac troponin T (cTnT) in serum samples is reported in this work. An extensive optimisation of assay parameters was conducted to achieve optimal detection strategy. Both direct and sandwich immunoassay formats were investigated and optimised. The response obtained was enhanced further by the use of gold nanoparticles (AuNPs) conjugated to the anti-cTnT detection antibody. A regeneration method was developed to enable the reuse of the SPR sensor for multiple sample application. The SPR immunosensor showed good reproducibility for cTnT detection in the concentration range of 25-1000 ng mL(-1) and 5-400 ng mL(-1) for the direct and sandwich assays in buffer, respectively. The linear regression analysis was performed and R(2) value was found as 0.99 for both assays. In order to optimise the sensor for serum analysis, nonspecific binding of serum proteins was reduced through the use of additives in the dilution buffer. To achieve greater sensitivity, the performance of the cTnT immunosensor sandwich assay in human serum was evaluated using non-modified and AuNP modified detector antibodies. A detection limit (LOD) for the immunosensor in 50% serum was assessed as 5 ng mL(-1) cTnT for the standard sandwich assay and 0.5 ng mL(-1) cTnT when using AuNP conjugated detector antibodies with a linear dynamic range of 0.5-40 ng mL(-1). The dissociation constant was found as 3.28 × 10(-9) M using Langmuir binding model which indicates high affinity between cTnT and its antibody. The proposed SPR immunosensor has a promising potential to be developed for point-of-care testing for the early diagnosis of acute myocardial infarction (AMI). This method can also be used for the rapid detection of biomarkers in central nervous system diseases. PMID:26695335

However, there is no study evaluating the clinical differences between patients who have undergone temporary pacing (TP and patients who have not. The present study was designed to investigate whether TP has any prognostic significance in inferior STEMI complicated by complete AVB.Methods: From January 2009 to December 2014, 295 consecutive patients diagnosed with inferior wall STEMI in a university hospital were reviewed. All of them underwent primary percutaneous coronary intervention (PCI. Among the 295 patients, there were 72 patients with complete AVB. The clinical characteristics, procedural data, and long-term major adverse cardiocerebrovascular events were compared in patients with and without TP.Results: Baseline clinical and procedural characteristics were similar between patients with and without TP. Patients with TP were more likely to present with cardiogenic shock; thus, additional interventions were attempted via a femoral approach, as patients received further treatment with intra-aortic balloon pumps and were subjected to additional cardiopulmonary resuscitation. Most cases of complete AVB were primarily caused by right coronary artery occlusion. After a median follow-up period of 344 (range, 105.5–641 days, major adverse cardiocerebrovascular events did not differ between the groups (P=0.528.Conclusion: We conclude that primary PCI without TP is acceptable in complete AVB-complicated acute inferior STEMI. To avoid delay in reperfusion, we suggest that primary PCI should be the first priority therapy rather than treating

A colonoscopy was performed and a nematode larva was found penetrating the mucosa of the ascending colon. Bleeding was observed at the site of penetration. Y-shaped lateral epidermal cords were seen from the cross section of the worm, which is a prominent feature of Anisakis larva. Molecular analysis using polymerase chain reaction of cytochrome oxidase 2 (cox2) gene confirmed the specimen to be larva of Anisakis simplex. PMID:27325803

    To assess the relationships between myocardial structure and function on cardiac magnetic resonance (CMR) imaging and sympathetic tone on {sup 123}I-metaiodobenzylguanidine ({sup 123}I-MIBG) scintigraphy early after myocardial infarction (MI). Ten patients underwent {sup 123}I-MIBG and {sup 99m}Tc-tetrofosmin rest cadmium zinc telluride scintigraphy 4 ± 1 days after MI. The segmental left ventricular (LV) relative radiotracer uptake of both {sup 99m}Tc-tetrofosmin and early {sup 123}I-MIBG was calculated. The day after scintigraphy, on CMR imaging, the extent of ischaemia-related oedema and of myocardial fibrosis (late gadolinium enhancement, LGE) was assessed. Accordingly, the extent of oedema and LGE was evaluated for each segment and segmental wall thickening determined. Based on LGE distribution, LV segments were categorized as ''infarcted'' (56 segments), ''adjacent'' (66 segments) or ''remote'' (48 segments). Infarcted segments showed a more depressed systolic wall thickening and greater extent of oedema than adjacent segments (p < 0.001) and remote segments (p < 0.001). Interestingly, while uptake of {sup 99m}Tc-tetrofosmin was significantly depressed only in infarcted segments (p < 0.001 vs. both adjacent and remote segments), uptake of {sup 123}I-MIBG was impaired not only in infarcted segments (p < 0.001 vs. remote) but also in adjacent segments (p = 0.024 vs. remote segments). At the regional level, after correction for {sup 99m}Tc-tetrofosmin and LGE distribution, segmental {sup 123}I-MIBG uptake (p < 0.001) remained an independent predictor of ischaemia-related oedema. After acute MI the regional impairment of sympathetic tone extends beyond the area of altered myocardial perfusion and is associated with myocardial oedema. (orig.)

    Background: Images of myocardial perfusion taken during an episode of chest pain have been used for patients in the emergency department. Objective: To evaluate the operating characteristics of {sup 99m}Tc-Tetrofosmin scintigraphy during an episode of chest pain to exclude the diagnosis of cute myocardial infarction. Methods: One hundred and eight patients admitted with chest pain, or up to four hours after the end of symptoms and non diagnostic electrocardiogram, underwent resting scintigraphy and measurement of troponin I concentrations. Patients with a history of myocardial infarction (MI) were not excluded (24 patients). Troponin I concentrations were determined at admission and 6 hours later. Nuclear physicians performed a blind analysis of the images, and myocardial infarction was confirmed whenever troponin I level increase was three times that of the control. Results: Resting perfusion image was abnormal in all 6 patients with MI. Only 1 patient had a normal image and increased troponin levels. Fifty-five patients had positive images without MI, and 46 patients had normal images and troponin levels. The prevalence of the disease was 6.5%. The sensitivity and specificity of the resting images during an episode of chest pain to diagnose MI was 85.7% and 45.5%, respectively. The negative predictive value was 97.7%. Conclusion: Patients undergoing chest pain protocol with SPECT showed an excellent negative predictive value to exclude diagnosis of myocardial infarction. These results suggest that resting perfusion image is an important tool at the chest pain unit. (author)

    Of the more than 5000 species of mushrooms known, 100 types are toxic and approximately 10% of these toxic types can cause fatal toxicity. A type of mushroom called Amanita phalloides is responsible for 95% of toxic mushroom poisonings. In this article, we report 2 cases of mushroom poisonings caused by Lactarius volemus, known as Tirmit by the local people. The patient and his wife were admitted to the emergency room with abdominal pain, nausea, and vomiting 20 hours after consuming Lactarius volemus, an edible type of mushroom. The patients reported that they had been collecting this mushroom from the mountains and eating them for several years but had never developed any clinicopathology to date. Further examination of the patients revealed a very rare case of acute pancreatitis due to mushroom intoxication. The male patient was admitted to the intensive care unit while his wife was followed in the internal medicine service, because of her relative mild clinical symptoms. Both patients recovered without sequelae and were discharged. In this article, we aimed to emphasize that gastrointestinal symptoms are often observed in mushroom intoxications and can be confused with acute pancreatitis, thus leading to misdiagnosis of patients. Early diagnosis and appropriate treatment can improve patients’ prognosis and prevent the development of complications. PMID:26835473

    Full Text Available Abstract Background Progressive heart failure due to remodeling is a major cause of morbidity and mortality following myocardial infarction. Conventional clinical imaging measures global volume changes, and currently there is no means of assessing regional myocardial dilatation in relation to ischemic burden. Here we use 3D co-registration of Cardiovascular Magnetic Resonance (CMR images to assess the long-term effects of ischemia-reperfusion injury on left ventricular structure after acute ST-elevation myocardial infarction (STEMI. Methods Forty six patients (age range 33–77 years underwent CMR imaging within 7 days following primary percutaneous coronary intervention (PPCI for acute STEMI with follow-up at one year. Functional cine imaging and Late Gadolinium Enhancement (LGE were segmented and co-registered. Local left ventricular wall dilatation was assessed by using intensity-based similarities to track the structural changes in the heart between baseline and follow-up. Results are expressed as means, standard errors and 95% confidence interval (CI of the difference. Results Local left ventricular remodeling within infarcted myocardium was greater than in non-infarcted myocardium (1.6% ± 1.0 vs 0.3% ± 0.9, 95% CI: -2.4% – -0.2%, P = 0.02. One-way ANOVA revealed that transmural infarct thickness had a significant effect on the degree of local remodeling at one year (P 20% (4.8% ± 1.4 vs −0.15% ± 1.2, 95% CI: -8.9% – -0.9%, P = 0.017. Conclusions The severity of ischemic injury has a significant effect on local ventricular wall remodeling with only modest dilatation observed within non-ischemic myocardium. Limitation of chronic remodeling may therefore depend on therapies directed at modulating ischemia-reperfusion injury. CMR co-registration has potential for assessing dynamic changes in ventricular structure in relation to therapeutic interventions.

    Full Text Available ABSTRACT: Introduction & Objective: It has been noted that the myocardial infarction is an increasing episode in Islamic Republic of Iran and there are many procedures and methods which can help to reduce the number of death from this ongoing event. The aim of this study was to determine the survival rate in those patients who have had acute myocardial infarction and its association with different variables. Materials & Methods: This descriptive analytic study evaluates 111 cases of acute myocardial infarction admitted in Yasuj Imam Sajjad hospital during the year 2004 and 2005. Data were collected using a questionnaire which was completed through direct interviewing by trained personnel. The data were analyzed by standard statistical tests using SPSS software. Results: The mean age of patients was 57± 12 years. The mean time of having access to physician after MI was 4 ± 2.2 hours. The mean time of reaching hospital after physician order was 5 ± 4.9 hours. The mean time of hospitalization was 4 ± 1.67 days. Considering the past history of these patients revealed that 31 percent were smokers, 16 percent had the history of previous ischemic heart disease, 63 percent had hypertension, 8 percent had diabetes mellitus, 95 percent had clip I, 95 percent had no previous block, 82 percent had MI with Q wave. The survival rate in our study was found to be 0.91 in the first 10 hours, 0.847 in the first day, 0.829 in the first 28 days, 0.820 in the first third months, 0.792 in the first six months and 0.771 in the first 10 months of disease. Conclusion: The mortality rate during the first month among the patients with heart failure turned out to be higher than that of the other similar studies performed in other parts of the country however, the annual survival rate proved to be less. The most important causes of survival after the stroke are being single, smoking, fatness and angina pain

  5. Detection of experimental acute myocardial infarction in dogs with electron beam CT

    International Nuclear Information System (INIS)

    Objective: The value and limitation of discovering the site, shape, density and size of acute myocardial infarction with enhanced volume scans of electron beam computed tomography (EBCT) in experimental dogs were assessed. Methods: The anterior descending and circumflex branches of the left coronary artery were ligated and infarction in the wall of left ventricle was created in six dogs. Enhancement volume scan was made with a EBCT scanner at 1.5, 6, 12, and 20 hour after the ligation and CT sectional images of dog heart were obtained. After finishing the scanning, the dogs were then scarified, and the samples were sent for electron and optic microscopes for pathologic examination. The morphologic findings of myocardial ischemia and infarction in CT images were carefully analysed. The CT numbers and the ratios of left ventricular myocardial and luminal CT number (M/L) in the myocardial ischemic and infarcted areas and normal areas were calculated. Results: The typical myocardial infarction in areas ligated were confirmed by ECG and pathology 20 hours after ligation. The site and shape of acute myocardial infarction were clearly shown on the EBCT images. The density of the ischemia and infarction area was significantly lower than that of the normal myocardium (P < 0.001). M/Ls of the low density areas and normal areas were 13.2% and 32.9%, respectively. The difference was significant (P < 0.001). Conclusions: With adequate scanning technique, the site shape, density and size of acute myocardial ischemia and infarction can be accurately assessed by EBCT

    A 26-year-old male suffered sustained chest pain. Electrocardiogram showed ST-segment elevation in the anteroseptal wall and reciprocal ST-segment change in the inferior wall. The troponin-I level and the white blood cell count were elevated. We gave a diagnosis of acute myocardial infarction. He underwent urgent coronary angiography, which revealed 90% diffuse stenosis in the middle right coronary artery and total occlusion in the proximal left anterior descending coronary artery (LAD). Since the electrocardiogram indicated that the culprit lesion was in the proximal LAD, we performed percutaneous coronary intervention. The coronary flow in the LAD was classified as thrombolysis in myocardial infarction trial 3. His coronary risk factors were obesity, smoking, family history, hypertension and diabetes, in addition to heterozygous familial hypercholesteremia (FH). Herein, we describe the case of a young patient with acute anteroseptal myocardial infarction and discuss the potential importance of controlling cholesterol levels in FH. PMID:27298669

    Myocardial infarction in humans provokes an acute phase response, and C-reactive protein (CRP), the classical acute phase plasma protein, is deposited together with complement within the infarct. The peak plasma CRP value is strongly associated with postinfarct morbidity and mortality. Human CRP binds to damaged cells and activates complement, but rat CRP does not activate complement. Here we show that injection of human CRP into rats after ligation of the coronary artery reproducibly enhance...

    Full Text Available Introduction. Acute myocardial infarction (AMI in a pregnant woman is rare. When occurring, AMI is a major cause of maternal and neonatal death. By presenting the following case we describe the dilemma concerning the timing of delivery. Case. A 36-year-old, multiparous women, at 35 6/7 weeks of gestation, suffered from an AMI due to an acute blockage of the left anterior descending artery (LAD. This was treated by angiographic thrombosuction and biodegradable stent placement. Within 5 hours after this procedure, a cesarean section (CS was performed because of a nonreassuring fetal condition. A healthy son with an Apgar score of 9/10 was born. The patient’s postoperative course was complicated by a big wound hematoma, a hemoglobin drop, and heart failure. Discussion. In case of AMI during pregnancy, the cardiological management has absolute priority. The obstetrical management is not outlined. In a nonreassuring fetal condition, delivery is indicated after stabilization of the mother. However, delivery after recent AMI and angiography will bring new risks of cardiologic stress and bleeding complications. The limited literature available tends to an expectant obstetrical management, but this case emphasizes the difficulty of waiting in suspected fetal distress.

    Acute myocardial infarction (AMI) remains the greatest threat to health in our society and is the most common cause of death in the United States and in many other Western industrialized countries. Recent data demonstrate that mortality from MI is continuing to decline. In these days of more aggressive management of acute MI (AMI) there has been a resurgence of interest in advances in thrombolytic therapy. However, observational studies of patients with AMI have shown that women sustaining an AMI have a worse prognosis than men. AMI is the number-one killer of women in the United States; approximately 247,000 of more than 520,000 deaths due to AMI that occur each year are among women, and almost one-third of the women are younger than forty-five years old. While there have been great advances in thrombolytic therapy, these advances have benefited men to a more significant degree than they have benefited women. The purpose of this paper is to critically review the efficacy of thrombolytic therapy in women with AMI with consideration of some of the key components of its effectiveness: mortality, bleeding risk, infarct-artery patency, ventricular function, and cardiac arrhythmia.

    Full Text Available Introduction. Spontaneous coronary artery dissection (SCAD is a very rare disease with poor prognosis. It mainly affects young women free of risk factors for coronary artery disease (CAD and women during the peripartum period. The prognosis for myocardial infarction caused by SCAD is poor, management is often difficult and guidelines still missing. Case report. We presented a woman with acute myocardial infarction of anterior wall of the left ventricle, caused by spontaneous dissection of medial segment of the left anterior descending coronary artery. We treated the patient with thrombolytic therapy and performed coronary angiography after that. Finally we decided to do nothing more. Two years later we performed coronary angiography again and founded the coronary artery normal. We also analyzed 19 cases publiched from 1996 to 2012 when coronary artery dissection had been treated with thrombolytic agent. Analysis revealed only one case of 19, with complication after treating SCAD with thrombolysis. Conclusion. Sometimes, regarding myocardial infarction in young women with no risk factors for CAD, especially in young women in peripartum, we should think about SCAD. The presented case, like eight others, demonstrates that good clinical outcomes can be achieved with thrombolysis. In spite of all this, we still need more data to verify that thrombolysis does not have to harm the therapy for SCAD. For the time being thrombolytic therapy could be an option.

  1. Trends in acute myocardial infarction hospitalization rates for US States in the CDC tracking network.

    Directory of Open Access Journals (Sweden)

    Evelyn O Talbott

    Full Text Available OBJECTIVES: We examined temporal trends, spatial variation, and gender differences in rates of hospitalization due to acute myocardial infarction. METHODS: We used data from the Centers for Disease Control National Environmental Public Health Tracking Network to evaluate temporal trends, geographic variation, and gender differences in 20 Environmental Public Health Tracking Network states from 2000 to 2008. A longitudinal linear mixed effects model was fitted to the acute myocardial infarction hospitalization rates for the states and counties within each state to examine the overall temporal trend. RESULTS: There was a significant overall decrease in age-adjusted acute myocardial infarction hospitalization rates between 2000 and 2008, with most states showing over a 20% decline during the period. The ratio of male/female rates for acute myocardial infarction hospitalization rates remained relatively consistent over time, approximately two-fold higher in men compared to women. A large geographic variability was found for age-adjusted acute myocardial infarction hospitalization rates, with the highest rates found in the Northeastern states. Results of two ecological analyses revealed that the NE region remained significantly associated with increased AMI hospitalization rates after adjustment for socio-demographic factors. CONCLUSIONS: This investigation is one of the first to explore geographic differences in AMI age adjusted hospital rates in individuals 35+ years of age for 2000-2008. We showed a decreasing trend in AMI hospitalization rates in men and women. A large geographic variability in rates was found with particularly higher rates in the New England/Mid-Atlantic region of the US and lower rates in the mountain and Pacific states of the tracking network. It appeared that over time this disparity in rates became less notable.

    Full Text Available Background: We sought to evaluate the impact of different therapeutic strategies on longitudinal regional myocardial systolic function in the early phase of acute myocardial infarction using strain rate imaging.Methods: A total of 38 patients (34 males, with first acute myocardial infarction (AMI were evaluated. Our patients were divided into 3 groups according to the kind of therapy. The mean age of the patients was 55 ± 9.4 years (range: 39- 75 years. Mean left ventricular ejection fraction (LVEF in the patients was 41 ± 10.7%. Primary percutaneous coronary intervention (PCI was performed in 10 patients. Sixteen patients were treated by thrombolytic therapy using streptokinase (SK and 12 were followed-up conservatively. All patients underwent a comprehensive echocardiography study including SR imaging within 3- 5 days after AMI. The parameters measured included peak systolic strain (peakε and strain rate (SRs, end-systolic strain (εes, post systolic shortening (PSS, time to peak systolic strain rate (tSRs, time to end of shortening (teSRs, post systolic strain (PSε, post-systolic strain index (PSI, PSS ratio (PSS/ εMax and peak postsystolic strain rate (SRPSS. Results: There was not any association either between WMSI and tå (P=0.4, or MI location and PSS ratio (P=0.13. But there was an inverse relationship between WMSI and mean SRS, especially when WMSI was more pronounced. A significant relationship was found between tε and teSRs with the kind of therapy (shorter in PCI group (P= 0.04. Using a simple linear regression model, no association was found between PSS ratio and SRs (â=0.056, P =0.70, PSI and teSRs (β= -0.772, P=0.12. Simple linear regression model showed a weak but significant relationship between PSI and Median tε (β = -0.851, P =0.04; r =0.33.Conclusion: Our study showed that PCI resulted in early recovery of regional systolic function of infarcted myocardium during the early stage of acute myocardial infarction.

    Full Text Available The protective effect of Compound Yangshen Granules was observed in myocardial infarction rat model. Rats were randomly divided into 6 groups: the model group, the control group (sham operated, the positive drug group, and small, medium, and large dosage of the Yangshen granule groups, respectively. The rats in the 3 Yangshen granule groups were orally administrated with 0.7 g/kg, 1.4 g/kg, and 2.8 g/kg for 7 consecutive days, whereas the rats of the positive drug group treated with 0.14 g/kg of Danshen Dropping Pills, and rats in the control and model groups orally administrated with saline. The rat model of acute myocardial infarction was established with ligation of coronary artery. Electrocardiograms at different time points, the blood rheology, myocardial enzymes, infarct size, and myocardial morphologic changes were measured. The results demonstrated that the granules could improve blood rheology, decrease st-segment of electrocardiograms and the activities of LDH and CK in serum, reduce myocardial infarction size, and alleviate myocardial histopathologic changes. In addition, the effect of the granules depended on the dose administrated orally. The results suggest that the Yangshen granules could produce cardioprotection effect and have potential benefits in the prevention of ischemic heart disease.

  5. Acute myocardial infarction. Clinical application of technetium 99m stannous pyrophosphates infarct scintigraphy

    International Nuclear Information System (INIS)

    Acute myocardial infarction is being recognized as a spectrum of clinical subsets. This appreciation has been brought about to a large degree by the development of several new tools that can be applied clinically to aid in evaluation of patients with acute infarction, and in some cases to provide short- and long-term prognostic information. In the realm of noninvasive methods, several tests utilizing radiopharmaceuticals and scintillation cameras have emerged and are rapidly becoming reliable diagnostic parameters in patients with coronary disease and infarction. Technetium-99m (stannous) pyrophosphate (TcPYP) scintigraphy, one of the first of these techniques to find clinical use, has been shown to be an accurate indicator of acute transmural myocardial infarction and provides added sensitivity and specificity to the diagnosis. Increased diagnostic accuracy, the dimension of visible localization, and the potential for infarct sizing promise physicians better understanding of a patient's clinical presentation and a more rational approach to management

    Sixteen patients with acute myocardial infarction underwent treatment with streptokinase up to 3 hours after the onset of chest pain. Nine patients (group I) received streptokinase within 1 hour of the onset of pain, and seven patients (group II) received it within 2 to 3 hours. All underwent multigated radionuclide ventriculography after streptokinase therapy and 1 week later. Percutaneous transluminal coronary angioplasty of the infarct artery was performed within 24 hours in all patients. An effort-limited treadmill stress test was performed before discharge. There was no mortality or serious complication. Mean peak total creatine kinase was 521 +/- 289 mU/ml in group I, and 1,614 +/- 709 mU/ml in group II (p less than 0.05). The mean initial left ventricular ejection fraction was 47 +/- 11% in group I and 37 +/- 10% in group II. After early angioplasty (within 24 hours) and at 1 week recovery, left ventricular ejection fraction increased to 53 +/- 9% in group I (p less than 0.05) and to 40 +/- 7% in group II (p = NS). Seven of the nine patients in group I had normal radionuclide ventriculograms at discharge compared with none of the seven patients in group II. Thrombolytic therapy administered less than 1 hour after the onset of symptoms of acute myocardial infarction followed by angioplasty of the infarct artery results in preservation of left ventricular function, whereas therapy given after 2 hours has only a limited effect.

These results suggest that there may be some protective effects of poly unsaturated fatty acid against myocardial infarction.

  12. Neural Mechanisms and Delayed Gastric Emptying of Liquid Induced Through Acute Myocardial Infarction in Rats

    International Nuclear Information System (INIS)

    In pathological situations, such as acute myocardial infarction, disorders of motility of the proximal gut can trigger symptoms like nausea and vomiting. Acute myocardial infarction delays gastric emptying (GE) of liquid in rats. Investigate the involvement of the vagus nerve, α 1-adrenoceptors, central nervous system GABAB receptors and also participation of paraventricular nucleus (PVN) of the hypothalamus in GE and gastric compliance (GC) in infarcted rats. Wistar rats, N = 8-15 in each group, were divided as INF group and sham (SH) group and subdivided. The infarction was performed through ligation of the left anterior descending coronary artery. GC was estimated with pressure-volume curves. Vagotomy was performed by sectioning the dorsal and ventral branches. To verify the action of GABAB receptors, baclofen was injected via icv (intracerebroventricular). Intravenous prazosin was used to produce chemical sympathectomy. The lesion in the PVN of the hypothalamus was performed using a 1mA/10s electrical current and GE was determined by measuring the percentage of gastric retention (% GR) of a saline meal. No significant differences were observed regarding GC between groups; vagotomy significantly reduced % GR in INF group; icv treatment with baclofen significantly reduced %GR. GABAB receptors were not conclusively involved in delaying GE; intravenous treatment with prazosin significantly reduced GR% in INF group. PVN lesion abolished the effect of myocardial infarction on GE. Gastric emptying of liquids induced through acute myocardial infarction in rats showed the involvement of the vagus nerve, alpha1- adrenergic receptors and PVN

    2016-01-01

    Full Text Available Abstract Background: Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression. Objectives: The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening markers and impaired ventricular-arterial coupling in decompensated heart failure patients. Methods: A total of 79 inpatients with acute decompensated heart failure were evaluated. Serum galectin-3 was determined at baseline, and during admission, transthoracic echocardiography and measurements of vascular indices by Doppler ultrasonography were performed. Results: Elevated pulse wave velocity and low arterial carotid distensibility are associated with heart failure in patients with preserved ejection fraction (p = 0.04, p = 0.009. Pulse wave velocity, carotid distensibility and Young’s modulus did not correlate with serum galectin-3 levels. Conversely, raised galectin-3 levels correlated with an increased ventricular-arterial coupling ratio (Ea/Elv p = 0.047, OR = 1.9, 95% CI (1.0‑3.6. Increased galectin-3 levels were associated with lower rates of left ventricular pressure rise in early systole (dp/dt (p=0.018 and raised pulmonary artery pressure (p = 0.046. High galectin-3 levels (p = 0.038, HR = 3.07 and arterial pulmonary pressure (p = 0.007, HR = 1.06 were found to be independent risk factors for all-cause mortality and readmissions. Conclusions: This study showed no significant correlation between serum galectin-3 levels and arterial stiffening markers. Instead, high galectin-3 levels predicted impaired ventricular-arterial coupling. Galectin-3 may be predictive of raised pulmonary artery pressures. Elevated galectin-3 levels correlate with severe systolic dysfunction and together with pulmonary hypertension are independent markers of

    Full Text Available Background: Coronary heart disease is multi-factorial in origin and its burden is expected to rise in developing countries, including India. Evidence suggests that the inflammation caused by infection is associated with the development of atherosclerosis and heart disease. An increasing number of clinical and experimental studies point to a contribution of various infectious organisms to the development of atherosclerosis in humans. Acute myocardial infarction (AMI is associated with atherosclerosis. Objectives: The objective of the following study is to study the association between Helicobacter pylori, Chlamydia pneumoniae and C-reactive protein (CRP with AMI. Materials and Methods: This group-matched case-control study was carried out in Government Medical College, Nagpur, Maharashtra, India. The study compared the risk of occurrence of AMI (outcome if subjects were ever-infected with H. pylori or C. pneumoniae; and their CRP positivity (exposure. Incident cases of myocardial infarctions in a tertiary care hospital were included as cases. Results: The study recruited 265 cases and 265 controls and detected an odds ratio (OR of 2.50 (95% confidence interval [CI]: 1.69-3.70 and an OR of 2.50 (95% CI: 1.71-3.65 for C. pneumoniae and H. pylori, respectively. Raised CRP levels had an OR of 3.85 (95% CI: 2.54-5.87. Conclusion: Although our study indicates the role of infections in the etiology of AMI in study population, the relative public health impact of these agents in the overall prevalence of AMI needs urgent research attention.

    Elderly patients with acute myocardial infarction have not been specifically studied in the context of a large randomized clinical trial. Estimates of the efficacy of available treatments are gleaned from subset analyses of clinical trials, retrospective analysis and singlecenter experiences. In western countries the population is aging and a disproportionate number of myocardial infarctions occur in the elderly. Usage of appropriate therapy in this age group is becoming increasingly important given the potential for benefit but also the potential for harm. Recent publications have found steady improvement in outcomes in the elderly population utilizing contemporary interventions.

    Full Text Available Problem statement: Ischemic cardiac manifestations have been reported in a various percentage of patients with anti-phospholipid antibodies. Data concerning the relation between anti- Phospholipid (aPL antibodies and myocardial infarction in subjects without evidence of overt autoimmune disease are conflicting. Anti-beta2 glycoprotein-I (anti-beta2-GPI antibody is detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of anti-beta2-GPI antibody in Acute Myocardial Infarction (AMI might shed light on etiologic mechanisms in the pathogenesis of acute coronary syndromes. The purpose of the present study was to determine association of plasma aPL antibodies, namely, antibeta2- GPI antibodies, with AMI. This study was designed to investigate whether prevalence of antibeta2- GPI antibodies, in patients who had acute myocardial infarction and to analyze their relationship with traditional cardiovascular risk factors. Approach: We investigated the prevalence of anti-beta2- GPI IgG in a well characterized group of patients with AMI as a case group. Sera from 74 patients with AMI and from 76 healthy subjects, matched for age and sex as a control group. Using ELISA to evaluate the presence of IgG isotype of anti-beta2-GPI autoantibodies in their sera. Results: The prevalence of anti-beta2-GPI IgG in the control group (10.50% resulted significantly lower than in patients with AMI (37.80% (pConclusion: Our findings suggest that anti-beta2-GPI IgG antibodies seemed to behave as independent risk factors for myocardial infarction, which may represent a link between autoimmunity and atherosclerosis in patients with acute myocardial infarction. Further studies with bigger patients are needed to explore association of anti-β2-GPI IgG with STEMI and NSTEMI.

    Full Text Available Serum histaminase and SGOT were estimated in 35 cases of acute myocardial infarction and 34 cases of ischaemic heart disease (Other than acute myocardial infarction and 30, age and sex match-ed, healthy subjects which served as controls, to evaluate the com-parison of time relation activity, diagnostic and prognostic value of histaminase and SGOT. The enzymes were estimated within 6 hours, then repeated -within 24 hours, 2nd day, 3rd day, 5th day, 10th day and 15th day, ascertained from the time o f pain in the chest. Raised histaminase levels were found in 97.14%; cases, while SGOT levels were found elevated in only 91.4% cases of acute myo-cardial infarction of which 30 were electrocardiographically proved and 5 had equivocal electrocardiographic evidence of acute infarc-tion like LBBB, complete heart block, ventricular tachycardia and old myocardial infarction. Furthermore elevation of histaminase was 6.2 times whereas of SGOT only 5.2 times above the mean normal value. Serum histaminase was found elevated in all the 6 cases who presented within 6 hours of infarction, while SGOT did not rise in any of these cases. Both histaminase and SGOT reached the peak levels on the 2nd day and persisted for whole of the first week. Higher levels of these enzymes were found associated with worse prognosis. Above observations show that the serum histaminase rises earlier than SGOT and can prove the diagnosis of myocardial infarction even when SGOT and ECG fail to reveal the diagnosis. It is a more sensitive index and has higher peak rise of levels than SGOT. How-ever its pattern of rise, fall and prognostic values are similar to that of SGOT.

    Objective: Myocardial cell regeneration therapy is one of the most researched topics in modern medical science. The objective of this study was to evaluate the clinical value of 99Tcm-methoxyisobutylisonitrile (MIBI) rest gated myocardial perfusion imaging in patients with acute myocardial infarction (AMI) treated by stem cell transplantation. Methods: Thirty-one patients with AMI were all treated by percutaneous coronary intervention (PCI). And 18 of them subsequently had mesenchymal stem cell (MSC) transplantation therapy. All the patients were examined by 99Tcm-MIBI rest gated myocardial perfusion imaging at the time before and after PCI to evaluate the left ventricular myocardial perfusion and function. The t-test was used to compare data statistically with SPSS 11.0. Results: The number of myocardial segments with perfusion abnormalities decreased in all the AMI patients 1 month after PCI. The number of myocardial segments with perfusion defects decreased 3 to 6 months after PCI in the patients treated by MSC transplantation (2.37 ± 1.09 and 2.21 ± 0.93 ) when compared with the control group without MSC transplantation therapy (3.24 ± 0.93 and 3.21 ± 1.05, t =2.32,2.79, both P 99Tcm-MIBI rest gated myocardial perfusion imaging is an effective functional imaging to evaluate the therapeutic response in patients with AMI treated by MSC transplantation.

    A 27 years old woman was admitted due to abdominal cramps, jaundice and oligoanuria, starting 48 hours after eating Chinese food. Hepatic biochemical tests, abdominal ultrasound and retrograde pyelography were normal. The urine was intensely orange colored and microscopic analysis was normal. The serum creatinine and urea nitrogen on admission were 4.59 and 42.5 mg/dl and rose to 13.5 and 72.4 mg/dl, respectively, at the 6th hospital day. Oliguria lasted only 48 hours. Dialysis was not used, since the patient was in good general condition and uremic symptoms were absent. On the 7th day, azotemia began to subside and at the 14th day, serum creatinine was 1.0 mg/dl. Before hospital discharge, she confessed the ingestion of 2.000 mg of phenazopyridine, during a nervous breakdown, aiming to sleep deeply. Remarkable was the persistence of the orange color of her urine during several days and the dissociation between the rate of increase of serum creatinine with respect to urea nitrogen. This is an unusual case of acute renal failure caused by an overdose of a drug, commonly prescribed for urinary tract infections. PMID:12879816

    A 72-year-old man, smoker, with insuline-dependent diabetes and dislipemia underwent left pneumonectomy. Several episodes of intraoperative hemodynamic instability associated with electrocardiographic ST segment alterations were attributed to surgical manipulation; ischemia was not suspected. Cardiorespiratory failure, related to extensive anterior infarction, developed a few minutes after admission to the postoperative intensive care unit (PICU). Cardiopulmonary resuscitation and mechanical ventilation were required. The patient responded to treatment with beta blockers, platelet antiaggregants and statins. Tube was removed a few hours later and the patient was discharged from the PICU on the fifth day. Pneumonectomy has a high rate of morbidity and mortality, with complications mainly arising in the lung and heart. Risk from anesthesia is considered to be great in this procedure, and for that reason it is essential to identify intraoperative myocardial ischemia so that it can be treated aggressively. In patients at high cardiovascular risk who undergo lung resection, intraoperative episodes of myocardial ischemia are associated with a high incidence of postoperative miocardial infarction. Therefore, careful postoperative monitoring is needed and measures should be taken to prevent angina. Early extubation should be avoided. PMID:12516493

    Objective. To study the mechanism and effects of blood perfusion to the acute ischemic region of myecardium through Ho-YAG laser channels with myocardial contrast echocardiography Methods. To produce the model of acute myocardial ischemia, we partially ligated the left anterior decending (IAD)coromry artery of canine hearts between 1st. and 2nd. diagonal branches and then performed transmyocardial revasmgafizafion in this region with Ho- YAG laser. Myocardial contrast echecardingmphy was made with a new gen-eration of ultrasound contrast agent and second harmonic imaging of this region before,after ischemia and after laser revascalarizafion. Pictures were taken with “R” wave trigger skill. Results. Acoustic demity derterming in the ischemia region (anterior wall)with MCE(myocardial contrast e-checardiography) was obviously decreased(5.40 ± 1.81) after the LAD was ligated,as compared with before( 11.69± 1.61, P 0.05). There were no dif-ferences in acoustic density in the lateral wall(as control)among these comprehensive three periods (P > 0.05). Con-trast in the laser region developed one cardiac cycle ahead of that in the non-iscbemic normal region. Conclusion. Acute ischemic myecardium can be perfused by oxygenated blood from the left ventricle through Ho-YAG laser channels. Evidenee of blood perfusion through laser channels during systolic phase was detected,and my-ocardial cormast ultrasonngtaphy using intravenous perfluorocarbon-exposed sonicated dextrose albumin may be regard-ed as a reliable method in the study of tranmlyecardial revasculariztion.

    Full Text Available Abstract Background Matrix metalloproteinases (MMPs constitute a family of zinc-dependent proteases (endopeptidases whose catalytic action is the degradation of the extracellular matrix components. In addition, they play the major role in the degradation of collagen and in the process of tissue remodeling. The present clinical study investigated blood serum levels of metalloproteinases- 1, -2, -3 and -9 in patients with acute and chronic aortic dissection, thoracic aortic aneurysm and acute myocardial ischemia compared to healthy individuals. Methods The blood serum levels of MMP-1, -2, -3 and -9 were calculated in 31 patients with acute aortic dissection, 18 patients with chronic aortic dissection, 18 patients with aortic aneurysm and in 13 patients with acute myocardial ischemia, as well as in 15 healthy individuals who served as the control group. Serum MMP levels were measured by using an ELISA technique. Results There were significantly higher levels of MMP-3 in patients with acute myocardial ischemia as compared to acute aortic dissection (17.33 ± 2.03 ng/ml versus 12.92 ± 1.01 ng/ml, p Conclusion Measurement of serum MMP levels in thoracic aortic disease and acute myocardial ischemia is a simple and relatively rapid laboratory test that could be used as a biochemical indicator of aortic disease or acute myocardial ischemia, when evaluated in combination with imaging techniques.

    Full Text Available Introduction: Myocardial infarction (MI with 25- 30% mortality rate is one of the most common causes of death in most countries. According to recent data, MI is an increasing event in Iran. The aims of this study were to determine the 1-year survival rate and its correlates with MI among patients. Methods: This nonconcurrent cohort study was done on 113 patients with first acute MI who had been admitted in Imam Hossein hospital during the year 2004. Kaplan-Maier product limit and log rank test for survival analysis were used. Results: From 113 patients studied, there were 73(64.6% males and their mean age was 63.9±13.1 (range 16-89. According to of the past history of these patients relived that 23.9% had been smokers. The most frequent risk factors were hypertensions (53.1%, history of previous ischemic heart disease (35.4%, diabetes mellitus (24.8% and heart block (6.2%. Thirty six (31.9% of them died in first one-year after admission. The 1-year survival rate was 69 percent. Significant predictors of 1-year survival in our study were administration of streptokinase and use of ß-blockers after discharge.

    Full Text Available BACKGROUND: Following an AMI, it is important for patients and their physicians to appreciate the subsequent risk of death, and the potential benefits of invasive cardiac procedures and secondary preventive therapy. Studies, to-date, have focused largely on high-risk populations. We wished to determine the risk of death in a population-derived cohort of 2,887 patients after a first acute myocardial infarction (AMI. METHODS: Logistic regression and survival analysis were conducted to investigate the effect of different baseline characteristics, pharmacological therapies and revascularization procedures on coronary heart disease (CHD and all-cause mortality outcomes. RESULTS: Within five years 44.4% of patients died (27.1% short-term [30 kg/m2; AHR = 1.39, 95%CI 1.01-1.90 increased the risk of longer-term mortality independent of other risk factors. CONCLUSIONS: It is encouraging that the coronary procedure PTCA and pharmacological secondary prevention therapies were found to be strongly associated with an important reduced risk of subsequent death, although not all patients received these interventions. Smoking, being obese and having cardiovascular related disease at baseline were also associated with an increased likelihood of longer-term mortality, independent of other baseline characteristics. Thus, the provision of smoking cessation, advice on diet (for obese patients and optimal treatment is likely to be crucial for reducing mortality in all patients after AMI.

  4. Tramadol Alleviates Myocardial Injury Induced by Acute Hindlimb Ischemia Reperfusion in Rats

    International Nuclear Information System (INIS)

    Organ injury occurs not only during periods of ischemia but also during reperfusion. It is known that ischemia reperfusion (IR) causes both remote organ and local injuries. This study evaluated the effects of tramadol on the heart as a remote organ after acute hindlimb IR. Thirty healthy mature male Wistar rats were allocated randomly into three groups: Group I (sham), Group II (IR), and Group III (IR + tramadol). Ischemia was induced in anesthetized rats by left femoral artery clamping for 3 h, followed by 3 h of reperfusion. Tramadol (20 mg/kg, intravenous) was administered immediately prior to reperfusion. At the end of the reperfusion, animals were euthanized, and hearts were harvested for histological and biochemical examination. The levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were higher in Groups I and III than those in Group II (p < 0.05). In comparison with other groups, tissue malondialdehyde (MDA) levels in Group II were significantly increased (p < 0.05), and this increase was prevented by tramadol. Histopathological changes, including microscopic bleeding, edema, neutrophil infiltration, and necrosis, were scored. The total injuryscore in Group III was significantly decreased (p < 0.05) compared with Group II. From the histological and biochemical perspectives, treatment with tramadol alleviated the myocardial injuries induced by skeletal muscle IR in this experimental model

  6. Implications of abnormal right ventricular thallium uptake in acute myocardial infarction

    International Nuclear Information System (INIS)

    The correlates of abnormal right ventricular (RV) thallium uptake were examined in 116 patients with documented acute myocardial infarction (AMI) who underwent predischarge thallium-201 scintigraphy at rest, radionuclide angiography and 24-hour ambulatory electrocardiography. The patients were separated into 2 groups: patients group 1 (n = 31) had increased RV thallium uptake and those in group 2 (n = 85) had no such uptake. The 2 groups were comparable in age, type and site of AMI, peak creatine kinase level, systolic blood pressure and heart rate. However, compared with group 2, group 1 had a lower mean left ventricular (LV) ejection fraction (33 +/- 15% vs 39 +/- 14%, p less than 0.05), higher prevalence of increased lung thallium uptake (45% vs 22%, p less than 0.02), more extensive LV perfusion defects (4.4 +/- 2.9 vs 3.0 +/- 3.0 segments, p less than 0.03) and more complex ventricular arrhythmias (55% vs 35%, p less than 0.05). At a mean follow-up of 6 months, 17 patients (8 in group 1 and 9 in group 2) died from cardiac causes. Actuarial life-table analysis showed that the survival rate was better in group 2 than in group 1 (Mantel-Cox statistics = 4.62, p = 0.03). Thus, patients with AMI and abnormal RV thallium uptake have worse LV function, more complex ventricular arrhythmias and worse prognosis

    2013-02-01

    Full Text Available Background:Raised concentrations of C-reactive protein (CRP have been reported to be strongly related to an adverse long term prognosis in patients with acute myocardial infarction (AMI. However, adjustments for clinical variables as well as interaction between variables have been incomplete. The aims of this study were to examine the predictive value of baseline concentrations of CRP for mortality after adjustment for important clinical variables and to compare the clinical usefulness of CRP with easily available clinical variables in the prediction of long term survival.Methods:Five hundred and thirty-one patients with AMI were included. A blood sample for CRP was obtained on admission. All patients were followed for a minimum of two years and death of any cause was recorded as the study end point.Results:In logistic regression analysis, the interaction term Age by Killip class > 1, the variable glomerular filtration rate as well as the interaction term Age by Atrial fibrillation were retained. The resulting model correctly predicted death or not in 81% of the patients. CRP did not contribute to the final model.Conclusions:CRP does not independently predict long-term mortality after an AMI after adjustments for clinical variables and interaction. CRP has no value beyond clinical variables in predicting death after AMI.

    Full Text Available Introduction. Ventricular septal rupture (VSR in the acute myocardial infarction (AMI is a rare but very serious complication, still associated with high mortality, despite significant improvements in pharmacological and surgical treatment. Therefore, hybrid approaches are introduced as new therapeutical options. Case Outline. We present an urgent hybrid approach, consisting of the initial percutaneous coronary intervention (PCI of the infarct-related artery, followed by immediate surgical closure of the ventricular septal rupture, for treatment of high risk, hemodynamically unstable female patient with AMI caused by one-vessel disease and complicated by VSR and cardiogenic shock. Since the operative risk was also very high (EUROSCORE II 37%, this therapeutic decision was based on the assumption that preoperative PCI could promptly establish blood flow and thereby lessen the risks, duration and complexity of urgent cardiosurgical intervention, performed on the same day. This approach proved to be successful and the patient was discharged from the hospital on the fifteenth postoperative day in stable condition. Conclusion. In selected cases, with high operative risk and unstable hemodynamic state due to AMI complicated by VSR, urgent hybrid approach consisting of the initial PCI followed by surgical closure of VSR may represent an acceptable treatment option and contribute to the treatment of this complex group of patients.

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

    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.

  10. A partial defect in technetium-99m pyrophosphate image suggesting cardiac rupture following acute myocardial infarction

    International Nuclear Information System (INIS)

    We present the case of a 70-year-old woman with acute myocardial infarction who died of cardiac rupture on the 2nd hospital day. Dual isotope single photon emission tomography (SPET) using thallium-201 chloride and technetium-99m pyrophosphate (PYP) perforemd on the 2nd hospital day showed a large perfusion defect in the anteroseptal wall on 201Tl image and a increased accumulation on 99mTc-PYP image in the anterior area consistent with a partial defect. Autopsy performed 1 h after death revealed a tear in the left ventricular anterior wall consistent with the defect on the 99mTc-PYP image. We propose that the finding of a partial defect in 99mTc-PYP is an interesting finding which may be associated with cardiac rupture following acute myocardial infarction. (orig.)

    Acute myocardial infarction is a common disease rarely seen as a complication of bone marrow transplantation in young patients. We report on a 25-year-old patient 3.5 years after bone marrow transplantation who suffered an acute anterior wall myocardial infarction complicated by cardiogenic shock. The patient was treated with thrombolysis and emergent coronary angioplasty but died a few hours following admission. We suggest that the combination of low-dose chest irradiation and prolonged immunosuppression with graft-versus-host disease contributed to the development of the coronary artery disease in this patient. Though rarely encountered, physicians caring for young patients after bone marrow transplantation should be aware of potential ischemic complications. PMID:12601497

    Neurogenic stunned myocardium (NSM) is syndrome of myocardial dysfunction following an acute neurological insult. We report a case of NSM that occurred intraoperatively in a pediatric patient undergoing endoscopic fenestration and shunt revision. Accidental outflow occlusion of irrigation fluid and ventricular distension resulted in an acute increase in heart rate and arterial blood pressure. Subsequently, the patient developed stunned myocardium with global myocardial hypokinesia and pulmonary edema. She was promptly treated intraoperatively then admitted to the pediatric intensive care unit with resolution of her symptoms within 12 h. She was later discharged to home on the fourth postoperative day. In the current endoscopic era, this report highlights the possibility of intraoperative NSM and neurogenic pulmonary edema in the pediatric population. Early detection and treatment with a team approach help to achieve optimal control of this life-threatening condition and improve the outcome. PMID:26314948

    Full Text Available The aim of this study was to determine prognostic factors for the risk of new vascular events during the first 6 months after acute myocardial infarction (AMI or atherothrombotic stroke (AS. We were interested in the prognostic role of endothelial progenitor cells (EPC and circulating endothelial cells (CEC.Between February 2009 and July 2012, 100 AMI and 50 AS patients were consecutively studied in three Spanish centres. Patients with previously documented coronary artery disease or ischemic strokes were excluded. Samples were collected within 24h of onset of symptoms. EPC and CEC were studied using flow cytometry and categorized by quartiles. Patients were followed for up to 6 months. NVE was defined as new acute coronary syndrome, transient ischemic attack (TIA, stroke, or any hospitalization or death from cardiovascular causes. The variables included in the analysis included: vascular risk factors, carotid intima-media thickness (IMT, atherosclerotic burden and basal EPC and CEC count. Multivariate survival analysis was performed using Cox regression analysis.During follow-up, 19 patients (12.66% had a new vascular event (5 strokes; 3 TIAs; 4 AMI; 6 hospitalizations; 1 death. Vascular events were associated with age (P = 0.039, carotid IMT≥0.9 (P = 0.044, and EPC count (P = 0.041 in the univariate analysis. Multivariate Cox regression analysis showed an independent association with EPC in the lowest quartile (HR: 10.33, 95%CI (1.22-87.34, P = 0.032] and IMT≥0.9 [HR: 4.12, 95%CI (1.21-13.95, P = 0.023].Basal EPC and IMT≥0.9 can predict future vascular events in patients with AMI and AS, but CEC count does not affect cardiovascular risk.

    Atrial fibrillation (AF) is the most frequent heart rhythm disorder in the general population and contributes not only to a major deterioration in quality of life but also to an increase in cardiovascular morbimortality. The onset of AF in the acute phase of myocardial infarction (MI) is a major event that can jeopardize the prognosis of patients in the short-, medium- and long-term, and is a powerful predictor of a poor prognosis after MI. The suspected mechanism underlying the excess mortality is the drop in coronary flow linked to the acceleration and arrhythmic nature of the left ventricular contractions, which reduce the left ventricular ejection fraction. The principal causes of AF-associated death after MI are linked to heart failure. Moreover, the excess risk of death in these heart failure patients has also been associated with the onset of sudden death. Whatever its form, AF has a major negative effect on patient prognosis. In recent studies, symptomatic AF was associated with inhospital mortality of 17.8%, to which can be added mortality at 1year of 18.8%. Surprisingly, silent AF also has a negative effect on the prognosis, as it is associated with an inhospital mortality rate of 10.4%, which remains high at 5.7% at 1year. Moreover, both forms of AF are independent predictors of mortality beyond traditional risk factors. The frequency and seriousness of silent AF in the short- and long-term, which were until recently rarely studied, raises the question of systematically screening for it in the acute phase of MI. Consequently, the use of continuous ECG monitoring could be a simple, effective and inexpensive solution to improve screening for AF, even though studies are still necessary to validate this strategy. Finally, complementary studies also effect of oxidative stress and endothelial dysfunction, which seem to play a major role in triggering this rhythm disorder. PMID:26525569

    Although fast food is affordable and convenient, it is also high in calories, saturated fat and sodium. The frequency of fast food intake at the time of, and after, acute myocardial infarction (AMI) is modifiable. However, patterns of fast food intake and characteristics associated with its consumption among AMI patients are unknown. We studied fast food consumption at the time of AMI and 6 months later in 2481 patients from the prospective, 24-center TRIUMPH study of AMI patients. Fast food ...

  17. The nursing care of nausea and vomiting occurred in interventional treatment for acute myocardial infarction

    International Nuclear Information System (INIS)

    Objective: To investigate the effective nursing measures of nausea and vomiting occurred in percutaneous coronary intervention for acute myocardial infarction. Methods: During the period from Jan. 2010 to Feb. 2011, percutaneous coronary intervention was carried out in 109 patients with acute myocardial infarction. Among the 109 patients, 21 developed nausea, 83 developed vomiting one to three times and 5 developed projectile vomiting for 4-5 times. For these patients the nursing assessment was conducted, while proper psychological care, symptomatic nursing, psychosomatic relaxation, guidance for vomiting posture, vomiting nursing, balanced replenishment of fluid, etc. were carried out in order to ensure the accomplishment of percutaneous coronary intervention. Results: After the employment of nursing measures, no recurrence of vomiting was seen in 21 patients, the percutaneous coronary intervention was uninterruptedly completed in 83 patients, and in five patients with severe vomiting the procedure was eventually accomplished. Conclusion: The effective nursing care of nausea and vomiting plays an important auxiliary role in performing percutaneous coronary intervention for acute myocardial infarction. (authors)

  18. Prognostic value of intravenous dipyridamole thallium scintigraphy after an acute myocardial ischemic event

    International Nuclear Information System (INIS)

    Seventy-seven patients recovering from an acute coronary event were studied by intravenous dipyridamole thallium scintigraphy to evaluate the prognostic value and safety of the test in this patient subset. Forty-four patients (58%) had unstable angina and 33 (42%) had an acute myocardial infarction. One death occurred within 24 hours of testing. Sixty-eight patients were followed for an average of 12 months; 25, 31 and 23% had a fixed, reversible or combined thallium defect on their predischarge thallium scan. During follow-up, 10 patients died or had a nonfatal myocardial infarction; in each case, a reversible or combined myocardial thallium defect was present. Univariate analysis of 17 clinical, scintigraphic and angiographic variables showed that a reversible thallium defect and the angiographically determined extent of coronary artery disease were predictors of future cardiac events. The extent of coronary disease and global left ventricular ejection fraction were predictors of subsequent reinfarction or death. Logistic regression analyses revealed that a reversible thallium defect (p less than 0.001) and the extent of coronary disease (p less than 0.009) were the only significant predictors of a cardiac event. When death or reinfarction were the outcome variables, the extent of coronary disease (p less than 0.02) and left ventricular ejection fraction (p less than 0.06) were the only variables selected. Thus, intravenous dipyridamole thallium scintigraphy after an acute coronary ischemic syndrome is a useful and relatively safe noninvasive test to predict subsequent cardiac events

However, several cardiovascular complications including hypertension, cardiomyopathy, stroke, pulmonary embolism, fatal and nonfatal arrhythmias, and myocardial infarction have been reported with supraphysiologic doses of anabolic steroids. We report a case of an acute ST-segment elevation myocardial infarction in a patient with traditional cardiac risk factors using supraphysiologic doses of supplemental, intramuscular testosterone. In addition, this patient also had polycythemia, likely secondary to high-dose testosterone. The patient underwent successful percutaneous intervention of the right coronary artery. Phlebotomy was used to treat the polycythemia acutely. We suggest that the chronic and recent “stacked” use of intramuscular testosterone as well as the resultant polycythemia and likely increased plasma viscosity may have been contributing factors to this cardiovascular event, in addition to traditional coronary risk factors. Physicians and patients should be aware of the clinical consequences of anabolic steroid abuse.Keywords: acute myocardial infarction, anabolic steroid use, polycythemia
