    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.

    Full Text Available Common uses of the granulocyte-colony stimulating factors in the clinical practice raise the concern about side effects of these agents. We presented a case report about an acute myocardial infarction with non-ST segment elevation during filgrastim administration. A 73-year-old man had squamous cell carcinoma of larynx with lung metastasis treated with the chemotherapy. Second day after the filgrastim, patient had a chest discomfort. An ECG was performed and showed an ST segment depression and negative T waves on inferior derivations. A coronary angiography had showed a critical lesion in right coronary arteria. This is the first study thats revealed that G-CSF can cause acute myocardial infarction in cancer patients without history of cardiac disease. Patients with chest discomfort and pain who are on treatment with G-CSF or GM-CSF must alert the physicians for acute coronary events.

    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.

    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.

    Myocardial infarction is the main cause of sudden death during physical exercise, particularly in subjects over 40 and may even occur in high-performance young athletes. Sports and physical activity have a beneficial effect in preventing cardiovascular diseases, but certain rules of prudence must be followed to avoid the risk of a severe coronary event. Myocardial infarction always occurs in particularly susceptible subjects with several risk factors, predominantly smoking, hypercholesterolemia, family history of atherosclerosis. Dietary factors, either before, during or after the exercise, are always found. Distribution of coronary lesions differs with age. Before 40 years, the coronary network is normal in 40% of the cases. The infarction is partially explained by platelet hyperaggregahility and coronary spasms at exercise or in the post-exercise period.

    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

    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.

    2012-06-01

    Acute myocardial infraction (AMI) in the obstetric patient is a rare event, although the incidence is rising due to advancing maternal age and pre-existing cardiac risk factors and medical co-morbidities. While atherosclerotic disease is the leading cause of AMI, coronary artery dissection is an important consideration in pregnancy and in the postpartum period. The physiological changes of pregnancy as well as pregnancy-specific risk factors can predispose the obstetric patient to AMI. Diagnosis of AMI can be challenging as symptoms may be atypical. Furthermore, diagnostic tests must be interpreted in the context of pregnancy. While the overall management of the obstetric patient with AMI is similar to that outside of pregnancy, drug therapy requires modification as some medications may be contraindicated in pregnancy and breastfeeding. There is limited information about prognosis and risk stratification but it is anticipated that future studies will address this issue.

    Full Text Available Background: the identification of factors related to mortality in acute myocardial infarction represents an essential element in the initial assessment of patients. Objective: to identify factors associated with in-hospital mortality in patients with acute myocardial infarction admitted to the Coronary Intensive Care Unit of Cienfuegos in 2010. Methods: we conducted a case series study, which included 241 patients with acute myocardial infarction admitted to the Coronary Intensive Care Unit of the Dr. Gustavo Aldereguía Lima General University Hospital of Cienfuegos in 2010. The variables analyzed were age, sex, personal medical history, type of acute myocardial infarction (according to electrocardiogram and topographic location, heart rate and blood pressure at admission, classification of heart failure according to Killip Kimball, creatinine, glucose, total cholesterol, triglycerides, CPK-MB, and cardiovascular adverse events during their hospital stay. Results: the average age of the patients was 65,6 years old, with male predominance. High blood pressure, smoking and previous myocardial infarction were the most relevant antecedents. Patients with no heart failure and preserved ejection fraction predominated. Most frequent cardiovascular adverse events were post-infarction angina, ventricular arrhythmias and cardiogenic shock. Conclusions: we found significant association with mortality and old age (> 70 years, tachycardia, blood glucose ≥ 7 mmol / l at admission, and the presentation of ventricular arrhythmias and cardiogenic shock during in-hospital evolution.Fundamento: la identificación de los factores relacionados con la mortalidad en el infarto agudo del miocardio representa un eslabón primordial en la evaluación inicial de los pacientes.

    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

    Sáez, P; Kuhl, E

    2016-01-01

    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.

    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

    The occurrence of a serious cardiac emergency following scorpion envenomation has rarely been reported and, when so, mostly presented as non-ST segment elevation myocardial infarction, cardiogenic shock, or myocarditis. Possible mechanisms include imbalance in blood pressure and coronary vasospasm caused by the combination of sympathetic excitation, scorpion venom-induced release of catecholamines, and the direct effect of the toxin on the myocardium. We report a case of a 55-year-old man who presented with acute inferior wall myocardial infarction (MI) within 2 h of being stung by a scorpion. Coronary angiogram revealed total thrombotic occlusion of the left circumflex artery, which was treated successfully with glycoprotein IIb/IIIa inhibitor, thrombus aspiration, antivenom serum, and supportive therapy. Therefore, life-threatening MI can complicate the clinical course during some types of scorpion envenomation and should be managed as an acute coronary syndrome. PMID:26875137

    Acute myocardial infarction is one of the leading causes of cardiovascular disease mortality in both men and women. Chest pain, which is often described as chest pressure, tightness, or a squeezing sensation, is the most frequent symptom in patients presenting with acute myocardial infarction. Although the diagnosis of acute myocardial infarction is often based on typical changes on a surface electrocardiogram and on changes in cardiac biomarkers, there is a need to better recognize and understand the impact of sex on symptoms among patients presenting with acute coronary syndrome or acute myocardial infarction. We briefly review the pathophysiology of ischemic symptoms, discuss potential mechanisms for variation in ischemic symptoms by sex, and summarize recent publications that have addressed sex differences in ischemic symptoms.

    Nanog is a potential stem cell marker and is considered a regeneration factor during tissue repair. In the present study, we investigated expression patterns of nanog in the rat heart after acute myocardial infarction by semi-quantitative RT-PCR, immunohistochemistry and Western blot analyses. Our results show that nanog at both mRNA and protein levels is positively expressed in myocardial cells, fibroblasts and small round cells in different myocardial zones at different stages after myocardial infarction, showing a spatio-temporal and dynamic change. After myocardial infarction, the nanog expression in fibroblasts and small round cells in the infarcted zone (IZ) is much stronger than that in the margin zone (MZ) and remote infarcted zone (RIZ). From day 7 after myocardial infarction, the fibroblasts and small cells strongly expressed nanog protein in the IZ, and a few myocardial cells in the MZ and the RIZ and the numbers of nanog-positive fibroblasts and small cells reached the highest peak at 21 days after myocardial infarction, but in this period the number of nanog-positive myocardial cells decreased gradually. At 28 days after myocardial infarction, the numbers of all nanog-positive cells decreased into a low level. Therefore, our data suggest that all myocardial cells, fibroblasts and small round cells are involved in myocardial reconstruction after cardiac infarction. The nanog-positive myocardial cells may respond to early myocardial repair, and the nanog-positive fibroblasts and small round cells are the main source for myocardial reconstruction after cardiac infarction.

    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

    After acute myocardial infarction, ventricular remodeling is characterized by changes at the molecular, structural, geometrical and functional level that determine progression to heart failure. Inflammation plays a key role in wound healing and scar formation, affecting ventricular remodeling. Several, rather different, components of the inflammatory response were studied as biomarkers in ST-elevation acute myocardial infarction. Widely available and inexpensive tests, such as leukocyte count at admission, as well as more sophisticated immunoassays provide powerful predictors of adverse outcome in patients with ST-elevation acute myocardial infarction. We review the value of inflammatory markers in ST-elevation acute myocardial infarction and their association with ventricular remodeling, heart failure and sudden death. In conclusion, the use of these biomarkers may identify subjects at greater risk of adverse events and perhaps provide an insight into the mechanisms of disease progression.

    Spontaneous coronary artery dissection(SCAD) is a rare disease that is usually seen in young women in left descending coronary artery and result in events like sudden cardiac death and acute myocardial infarction. A 70-year-old man was admitted to the emergency department with chest pain which started 1 h ago during a relative’s funeral. The initial electrocardiography demonstrated 2 mm ST-segment depression in leads V1-V3 and the patient underwent emergent coronary angiography. SCAD simultaneously in two different coronary arteries [left anterior descending(LAD) artery and left circumflex(LCx)] artery was detected and SCAD in LCx artery was causing total occlusion which resulted in acute myocardial infarction. Successful stenting was performed thereafter for both lesions. In addition to the existence of SCAD simultaneously in two different coronary arteries, the presence of muscular bridge and SCAD together at the same site of the LAD artery was another interesting point which made us report this case.

    Objective To investigate the characteristics and efficacy of prehospital care in patients suffering sudden cardiac arrest caused by acute myocardial infarction. Methods Eighty patients suffering sudden cardiac arrest caused by acute myocardial infarction who were admitted to the emergency department of our hospital from February 2012 to May 2013 were enrolled in our study. All patients received prehospital care. Their clinical data were analyzed retrospectively.Results Of all patients, 48 (60%) were rescued successfully and 32 (40%) died. Among the patients who were rescued successfully, 25% (4/16) were aged not less than 65 years, which was significantly lower than that of death group (70.8%, 17/24). Cardiopulmonary resuscitation and electrical defibrillation were performed significantly earlier in the successful rescue group than in the death group. The rate of endotracheal intubation was 18.8% (3/16) in successful rescue group, significantly lower than that in death group (45.8%, 11/24) (P<0.05). ConclusionTo strengthen emergency network configuration, spread first-aid knowledge, well establish pre-hospital emergency procedures, and strengthen standardized treatment can significantly increase the treatment success rate in patients suffering sudden cardiac arrest caused by acute myocardial infarction and ensure their life safety, which have a very positive significance and are worthy of attention at all levels.%目的探讨急性心肌梗死心脏骤停院前急救特点及效果。方法本次共选取80例急性心肌梗死心脏骤停的患者作研究对象,均为我院急诊科2012年2月至2013年5月收治,行完善的院前急救,回顾分析临床资料。结果本次选取病例中,抢救成功48例,占60%,死亡32例,占40%。抢救成功患者年龄逸65岁占25%(4/16),明显少于死亡组70.8%(17/24),CPR、电除颤时间明显早于死亡组,气管插管人数抢救成功组为18.8%(3/16),明显低于死亡组45

    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

    Cardiogenic shock (CS) is still the predominant cause of in-hospital death in patients with acute myocardial infarction, although mortality has been reduced in recent years. Early percutaneous coronary intervention and coronary artery bypass grafting are causal therapies implemented in CS, supported by catecholamines, fluids, intra-aortic balloon pumping, and also active percutaneous assist devices. There is only limited evidence from randomized studies of any of these treatments in CS, except for early revascularization and the relative ineffectiveness of intra-aortic balloon pumping. This review will present treatment pathways of CS complicating acute myocardial infarction, with a major focus on revascularization, intensive care unit treatment, and mechanical support devices.

    Cardiovascular disease is the leading cause of mortality in American women. Since 1984, the annual cardiovascular disease mortality rate has remained greater for women than men; however, over the last decade, there have been marked reductions in cardiovascular disease mortality in women. The dramatic decline in mortality rates for women is attributed partly to an increase in awareness, a greater focus on women and cardiovascular disease risk, and the increased application of evidence-based treatments for established coronary heart disease. This is the first scientific statement from the American Heart Association on acute myocardial infarction in women. Sex-specific differences exist in the presentation, pathophysiological mechanisms, and outcomes in patients with acute myocardial infarction. This statement provides a comprehensive review of the current evidence of the clinical presentation, pathophysiology, treatment, and outcomes of women with acute myocardial infarction.

    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

    1995-07-01

    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.

    Cardiogenic shock complicates approximately 5-10% of cases with acute myocardial infarction and carries a poor prognosis. Early revascularization remains the cornerstone treatment of cardiogenic shock complicating myocardial infarction. Inotropic and/or vasopressor agents can be used for haemodynamic stabilization, although this comes at the expense of increased myocardial oxygen consumption and extended myocardial ischaemia. In recent years, the use of mechanical circulatory support has significantly increased. However, there is only limited data available from randomized trials evaluating the different percutaneous support systems. This review summarizes the available literature concerning the management of cardiogenic shock and gives an overview of the recommendations of the European and German-Austrian guidelines on cardiogenic shock.

  13. 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)

    Myocardial infarction is a relevant cardiovascular event worldwide for morbidity and mortality. It has been theorized that acute myocardial infarctions (AMIs) and other acute coronary events that are precipitated by atherosclerosis are due to arterial blockage from fat deposits. It is now known, however, that atherosclerosis involves more than just lipids. Inflammation has also been studied extensively to play a substantial role in myocardial infarction. There have been debates and conflicting reports over the past few years about the value of assessing levels of C-reactive protein and other biomarkers of inflammation for the prediction of cardiovascular events. Several studies have shown that CRP is not only an inflammatory marker, but also involved in the pathogenesis of myocardial infarction. Studies have linked atherogenesis and rupture of atherosclerotic lesion to endothelial dysfunction. CRP directly inhibits endothelial cell nitric oxide (NO) production via destabilizing endothelial NO synthase (eNOS). Decreased NO release causes CRP mediated inhibition of angiogenesis, stimulating endothelial cell apoptosis. CRP can also activate the complement system through the classical pathway. Complement activation plays an important role in mediating monocyte and neutrophil recruitment in an injured myocardium and may therefore lead to increase in infarct size. This article discusses the possible roles of CRP in complement activation, endothelial dysfunction and its impact on the development of myocardial infarction. We also reviewed the possible therapeutic approaches to myocardial infarction.

    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

  5. Thrombus aspiration in acute myocardial infarction.

    Mahmoud, Karim D; Zijlstra, Felix

    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.

    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.

    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

    2007-01-01

    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.

    Acute myocardial infarction is a severe ischemic disease responsible for heart failure and sudden death. Here, we show that after acute myocardial infarction in mice, mature B lymphocytes selectively produce Ccl7 and induce Ly6Chi monocyte mobilization and recruitment to the heart, leading to enhanced tissue injury and deterioration of myocardial function. Genetic (Baff receptor deficiency) or antibody-mediated (CD20- or Baff-specific antibody) depletion of mature B lymphocytes impeded Ccl7 production and monocyte mobilization, limited myocardial injury and improved heart function. These effects were recapitulated in mice with B cell–selective Ccl7 deficiency. We also show that high circulating concentrations of CCL7 and BAFF in patients with acute myocardial infarction predict increased risk of death or recurrent myocardial infarction. This work identifies a crucial interaction between mature B lymphocytes and monocytes after acute myocardial ischemia and identifies new therapeutic targets for acute myocardial infarction.

    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.

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.

    A 67-year-old Caucasian woman presented to clinic with a 2-month history of worsening shortness of breath on exertion and a single episode of chest pain 1 week before. Her ECG in clinic showed ST elevation inferiorly and she was admitted from clinic for further investigations as inpatient. She was initiated on the acute coronary syndrome protocol and underwent emergency left heart catheterisation on the day of admission. The coronary angiogram revealed large aneurysmal dilations in the right coronary artery and left main stem. A ventriculogram showed poor left ventricular (LV) systolic function in line with subsequent transthoracic echocardiogram, which revealed her to have an left ventricular ejection-fraction (LVEF) of approximately 20%. It was agreed with the cardiothoracic surgeons to treat the aneurysms non-operatively and start low-molecular weight heparin. Furthermore the underlying biventricular impairment was treated with ACE-inhibitors, β-blockers and diuretic therapy (loop and potassium-sparing). The strategy was to prevent further thrombus formation with the aneurysmal vessels and to achieve this the patient was initiated on lifelong warfarin. Other medical risk factors were optimised and patient started on statin medication. The aneurysm was monitored with serial CTs with a view to reconsider surgical intervention if any evidence of dilation. This case highlights an unusual cause of ST elevation myocardial infarction.

    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

    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. .

    The interval from the first alert of the healthcare system to the initiation of reperfusion therapy (system delay) is associated with mortality in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (pPCI). The importance of system delay...... in patients treated with fibrinolysis versus pPCI has not been assessed. We obtained data on system delay from the Danish Acute Myocardial Infarction-2 study, which randomized 1,572 patients to fibrinolysis or pPCI. The study end points were 30-day and 8-year mortality.

    Myocardial infarction is a leading cause of death, and cardiac rupture following myocardial infarction leads to extremely poor prognostic feature. A large body of evidence suggests that Akt is involved in several cardiac diseases. We previously reported that Akt-mediated Girdin phosphorylation is essential for angiogenesis and neointima formation. The role of Girdin expression and phosphorylation in myocardial infarction, however, is not understood. Therefore, we employed Girdin-deficient mice and Girdin S1416A knock-in (Girdin(SA/SA)) mice, replacing the Akt phosphorylation site with alanine, to address this question. We found that Girdin was expressed and phosphorylated in cardiac fibroblasts in vitro and that its phosphorylation was crucial for the proliferation and migration of cardiac fibroblasts. In vivo, Girdin was localized in non-cardiomyocyte interstitial cells and phosphorylated in α-smooth muscle actin-positive cells, which are likely to be cardiac myofibroblasts. In an acute myocardial infarction model, Girdin(SA/SA) suppressed the accumulation and proliferation of cardiac myofibroblasts in the infarcted area. Furthermore, lower collagen deposition in Girdin(SA/SA) mice impaired cardiac repair and resulted in increased mortality attributed to cardiac rupture. These findings suggest an important role of Girdin phosphorylation at serine 1416 in cardiac repair after acute myocardial infarction and provide insights into the complex mechanism of cardiac rupture through the Akt/Girdin-mediated regulation of cardiac myofibroblasts.

    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

    Studies demonstrate that acute myocardial infarction (AMI) mortality can be reduced if reperfusion therapy is initiated within 1 hour of AMI symptom onset. 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

    This study aimed to investigate the effect of hydroxy safflower yellow A (HSYA) on myocardial apoptosis after acute myocardial infarction (AMI) in rats. We randomly divided 170 male Wistar rats into 6 groups (N = 23): normal control, sham, control, SY (90 mg/kg), HSYA high-dose (HSYA-H, 40 mg/kg), and HSYA low-dose groups (HSYA-L, 20 mg/kg). Myocardial ischemic injury was induced by ligating the anterior descending coronary artery, and the degree of myocardial ischemia was evaluated using electrocardiography and nitroblue tetrazolium staining. Bax and Bcl-2 expressions in the ischemic myocardium were determined using immunohistochemical analysis. Peroxisome proliferator-activated receptor-γ (PPAR-γ) expression in the myocardium of rats with AMI was determined using reverse transcription-polymerase chain reaction. Compared to rats in the control group, those in the HYSA-H, HSYA-L, and SY groups showed a decrease in the elevated ST segments and an increase in the infarct size. The rats in the drug-treated groups showed a significantly lower percentage of Bax-positive cells and a significantly higher percentage of Bcl-2-positive cells than those in the control group (P myocardial ischemia in rats, possibly by increasing the level of Bcl-2/Bax, and PPAR-γ may be not a necessary link in this process.

    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.

  19. 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)

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

    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 BACKGROUND : Although acute myocardial infarction was believed to be an uncommon entity in the young, of late there has been a rising incidence in this group of population. The analysis of its clinical profile, including the etiologic and the risk factors gains much importance, for the preventive purpose. AIMS AND OBJECTIVES: To study the clinical profile of acute MI, including the evaluation of the cardiac enzyme markers, the risk factors, the management and the complications and outcome of this g roup of patients aged 40 years or younger. RESULTS: Majority of patients belonged to the age group of 36 - 40years. 31 patients were overweight and 16 patients were obese. 46 patients (67.64% had anterior wall myocardial infarction, 22 patients had inferior wall myocardial infarction (32.35% and ST - elevation myocardial infarction was found in 69.2% of patients. Smoking/tobacco use was the most common risk factor (64.70% followed by dyslipidemia (60.29%, metabolic syndrome (52.94% diabetes mellitus (52.94 %, hyperhomocysteinemia (52.94%, alcohol consumption (48.52%, hypertension (34%, family history (26.47%, obesity (23.52%. Other than these, two patients had chronic kidney disease stage 3, two female patients were irregular oral contraceptive pill us ers, one was diagnosed as systemic lupus erythematosus and another patient had antiphospholipid antibody syndrome. Conclusions: Apart from early diagnosis and adequate treatment of acute MI in young patients, it is also essential to identify and prevent or control the risk factors at primary and secondary level.

    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.

    Full Text Available Cardiac metastases in bronchogenic carcinoma may occur due to retrograde lymphatic spread or by hematogenous dissemination of tumour cells, but direct invasion of heart by adjacent malignant lung mass is very uncommon. Pericardium is frequently involved in direct cardiac invasion by adjacent lung cancer. Pericardial effusion, pericarditis, and tamponade are common and life threatening presentation in such cases. But direct invasion of myocardium and endocardium is very uncommon. Left atrial endocardium is most commonly involved in such cases due to anatomical contiguity with pulmonary hilum through pulmonary veins, and in most cases left atrial involvement is asymptomatic. But myocardial compression and invasion by adjacent lung mass may result in myocardial ischemia and may present with retrosternal, oppressive chest pain which clinically may simulate with the acute myocardial infarction (AMI. As a result, it leads to misdiagnosis and delayed diagnosis of lung cancer. Here we report a case of non-small-cell carcinoma of right lung which was presented with asymptomatic invasion in left atrium and retrosternal chest pain simulating AMI due to myocardial compression by adjacent lung mass, in a seventy-four-year-old male smoker.

    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.

    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. .

    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.

    The prevalence of thrombophilia and dyslipidemia among young survivors of acute coronary syndrome has not been clearly defined. The purpose of the current study was to investigate the prevalence of multiple markers of thrombophilia and dyslipidemia in a cohort of consecutive young survivors of acute coronary syndrome. The study cohort included 156 consecutive young patients (men women acute coronary syndrome. Analysis included baseline, clinical and epidemiological characteristics, angiographic coronary anatomy, echocardiographic evaluation, extensive lipid and thrombophilia laboratory profiles, and in-hospital and 1-year clinical outcomes for all patients. Acute myocardial infarction was diagnosed in 142 (92 %) patients, of whom 108 (72 %) had ST-segment elevation. Eighteen (12 %) patients had no traditional risk factors. Low levels of high-density lipoprotein (30 mg/dL). Eighteen (12 %) patients were diagnosed with antiphospholipid antibody syndrome (APS), and 73 (47 %) had at least one laboratory finding consistent with thrombophilia. Patients with APS had significantly higher levels of Lp(a) (46 ± 32 vs. 29 ± 31 mg/dL, p = 0.005). APS is a common prothrombotic state found in young survivors of acute coronary syndrome. Lp(a) levels are elevated among APS patients who present with premature acute coronary syndrome.

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

    Topaz, On

    1993-06-01

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

    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.

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

    Directory of Open Access Journals (Sweden)

    Santosh

    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

  16. Risk of stroke after acute myocardial infarction among Chinese

    Institute of Scientific and Technical Information of China (English)

    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.

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...

    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.

  9. 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

    Therapy of acute myocardial infarction (STEMI and NSTEMI) in diabetics does not principally differ from that of non-diabetic patients. Due to the higher mortality in diabetics reperfusion measures, such as direct percutaneous coronary intervention (PCI), should be rapidly performed. An intensive drug treatment with thrombocyte aggregation inhibitors, angiotensin-converting enzyme (ACE) inhibitors and beta-receptor blocking agents must be carried out according to the current guidelines. An important factor is the high risk of renal failure due to the contrast dye administered during PCI in the presence of pre-existing diabetic kidney damage which should be limited to 100 ml if possible. Direct PCI should be limited to the infarcted vessel. After stabilization a comprehensive strategy to cure coronary artery disease, whether with PCI or coronary artery bypass graft (CABG) should be finalized. If severe coronary 3-vessel disease is present, CABG should be favored in diabetic patients. After surviving an acute myocardial infarction differentiated metabolic monitoring is mandatory.

  11. Relationship Between Periodontal Disease and Acute Myocardial Infarction

    2008-07-01

    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.

    We used a porcine model of acute myocardial infarction to study the signal evolution of ischemic myocardium on diffusion-weighted magnetic resonance images (DWI). Eight Chinese miniature pigs underwent percutaneous left anterior descending or left circumflex coronary artery occlusion for 90 minutes followed by reperfusion, which induced acute myocardial infarction. We used DWI preprocedurally and hourly for 4 hours postprocedurally. We acquired turbo inversion recovery magnitude T2-weighted images (TIRM T2WI) and late gadolinium enhancement images from the DWI slices. We measured the serum myocardial necrosis markers myoglobin, creatine kinase-MB isoenzyme, and cardiac troponin I at the same time points as the magnetic resonance scanning. We used histochemical staining to confirm injury. All images were analyzed qualitatively. Contrast-to-noise ratio (the contrast between infarcted and healthy myocardium) and relative signal index were used in quantitative image analysis. We found that DWI identified myocardial signal abnormity early (clinical serologic biomarkers.

    OPINION STATEMENT: Using an implantable cardiac monitor (ICM) in patients with acute myocardial infarction (MI) allows continuous electrocardiogram monitoring and provides a much more detailed picture of the incidence of brady- and tachyarrhythmias than conventional follow-up. The CARISMA study...... was the first to use the ICM in post-MI patients with moderate to severe left ventricular systolic dysfunction. Atrial fibrillation (AF) events lasting longer than 30 s were associated with an almost threefold increase in the risk of major cardiac events. This confirms the current definition of clinically...... causes of AF such as progressive left ventricular dysfunction or myocardial ischemia. Asymptomatic, especially nightly, bradycardia episodes including high-degree 2°-3° atrioventricular (AV) block, sinus bradycardia, and sinus arrest were frequently documented by ICM in the CARISMA study.

    Acute myocardial infarction with simultaneous occlusions of two main branches is very rare, and it is difficult to presume it before performing emergent CAG. We encountered two such cases recently. Case 1 was a 77 year-old woman. She was admitted to our hospital because of anterior chest pain. Emergent CAG disclosed complete occlusions of RCA-Segment 3 and LAD-Segment 7. ICT improved both of them to 90% stenoses. Case 2 was a 58 year-old man. He was admitted to our hospital because of upper abdominal pain. Emergent CAG disclosed complete occlusions of RCA-Segment 2 and LAD-Segment 6. ICT improved the former to 99% stenosis, and the latter recanalized. Myocardial dual scintigrams performed during the acute periods showed findings which were consistent with simultaneous occlusion of the two main branches in both cases. We could consider such reasons as coronary vasospasm, state of hyper-coagulability at the onset of myocardial infarction and depression of coronary pressure etc as possible causes of these cases.

    Full Text Available Negative pressure pulmonary edema (NPPE is defined as fluid transudation into the pulmonary interstitium which occurs as a result of elevated negative intrathoracic pressure caused by the upper respiratory tract obstruction and strong inspiratory effort. NPPE is usually seen during emergence from general anesthesia in the early post-operative period especially after upper respiratory tract surgery. We present a case of a 37-year-old male patient who underwent septoplasty operation and developed NPPE which could not diagnosed and progressed to acute subendocardial myocardial infarction.

    The aim of this study was to investigate if acute myocardial infarction can be detected by post-mortem cardiac magnetic resonance (PMMR) at an earlier stage than by traditional autopsy, i.e., within less than 4 h after onset of ischemia; and if so, to determine the characteristics of PMMR findings in early acute infarcts. Twenty-one ex vivo porcine hearts with acute myocardial infarction underwent T2-weighted cardiac PMMR imaging within 3 h of onset of iatrogenic ischemia. PMMR imaging findings were compared to macroscopic findings. Myocardial edema induced by ischemia and reperfusion was visible on PMMR in all cases. Typical findings of early acute ischemic injury on PMMR consist of a central zone of intermediate signal intensity bordered by a rim of increased signal intensity. Myocardial edema can be detected on cardiac PMMR within the first 3 h after the onset of ischemia in porcine hearts. The size of myocardial edema reflects the area of ischemic injury in early acute (per-acute) myocardial infarction. This study provides evidence that cardiac PMMR is able to detect acute myocardial infarcts at an earlier stage than traditional autopsy and routine histology.

    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.

    Myocardial infarction (MI) associated with sildenafil citrate is seen rarely in patients without any history of coronary artery disease. We report a nitrate-free patient with a history of cardiovascular risk factors who developed acute MI after taking sildenafil. A 44-year-old man diagnosed with acute anterior ST segment elevation MI 120 min after self-administration of 150 mg sildenafil was admitted before attempting any sexual intercourse. The coronary angiography revealed 99% occlusion of the left anterior descending artery (LAD) and a bare-metal stent was implanted. He was discharged after 5 days without any complication. Sildenafil may cause coronary steal or may lead to vasodilation causing hypotension in patient with pre-existing cardiovascular disease, especially in patients on nitrate therapy. Our patient was nitrate free, with normal blood pressure values. Emotional stimulation associated with anticipated sexual activity may have been a triggering factor for vulnerable coronary plaque rupture.

    Full Text Available ABSTRACT Introduction: Stroke is more common in patients with cerebral microembolisms. Frequency of cerebral microembolisms (high intensity transient signals, HITS in acute myocardial infarction has been reported about 17%. The factors that influence on microembolism after myocardial infarction (MI are not definitive. Type of MI, Ejection fraction, Hx of Streptokinase is the factors that were studied. Methods: During three years we studied the frequency of cerebral microembolisms in AMI patients, we studied forty patients with microembolism as a case group and ninety patients without microembolism as a control group. We detected microembolism in patients by transcranial doppler study within 72 houre after myocardial infarction. Two-dimensional echocardiogram was performed for all patients during hospitalization. Excluding criteria were prosthetic heart valves, carotid stenosis >50% and poor window for TCD monitoring. Results: number of patients who had history of receiving SK were significantly more common in case group in comparison to control group. OR 2.4 CI(1.1-5.2 The frequency was more prevalent in anterolateral MI in comparison to inferior MI.OR=3.3 CI(1.4-7.4. Ejection fraction has no significant effect on frequency of microembolism. OR 0.5 CI(0.2-1.3.Hypokinesia is also a risk factor for increasing risk of microembolism. OR 4.5 CI(1.4.13.8 Discussion: frequency of microembolism has been increased in patients with history of streptokinase or in the type of Anterolateral MI or wall motion abnormality, so we should be careful for risk of microembolism in this groups.

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.

    Objective To investigate the influencing factors for prehospital delay in patients with acute myocardial infarction (AMI).Methods A total of 807 consecutive patients with AMI who presented to the emergency department of Beijing Anzhen Hospital were analyzed. The influence of several potential risk factors on the prehospital delay time (PDT) was evaluated by comparing patients admitted more than 2 hours after onset of chese pain with those admitted within 2 hours after onset. Results Among 807 patients, 402 came to the hospital within 2 hours while the others arrived at the hospital after 2 hours. The median PDT was 130 min. Among the potential variables, advanced age, history of diabetes mellitus, occurrence of symptom at night and use of emergency medical service significantly affected PDT by multivariate analysis. Conclusion Interventions aimed at reducing the prehospital delay in AMI should primarily focus on the awareness of the risk and help-seeking behavior of patients.

    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.

    Full Text Available Dabigatran etexilate is a recently approved direct thrombin inhibitor (DTI, which is superior to warfarin in the prevention of stroke and systemic embolism in patients with atrial fibrillation (AF. However, dabigatran use is associated with an increased risk of myocardial infarction (MI compared to warfarin. The mechanisms for this association effect remain speculative. We present a case of an acute MI and cardiac arrest in a patient with chronic AF who had been recently switched from warfarin to dabigatran. Urgent coronary angiography, at St. Michael’s hospital (Toronto, Canada, revealed evidence of thromboembolism to the distal posterior descending artery. The patient was treated medically and switched back from dabigatran to warfarin. He did well and was discharged after an uneventful stay in the coronary care unit.

    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.

    2016-09-01

    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.

    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.

    2011-12-01

    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.

    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.

    Full Text Available Abstract Background The role of infarct size on left ventricular (LV remodeling in heart failure after an acute ST-segment elevation myocardial infarction (STEMI is well recognized. Infarct size, as determined by cardiovascular magnetic resonance (CMR, decreases over time. The amount, rate, and duration of infarct healing are unknown. Methods A total of 66 patients were prospectively enrolled after reperfusion for an acute STEMI. Patients underwent a CMR evaluation within 1 week, 4 months, and 14 months after STEMI. Results Mean infarct sizes for the 66 patients at baseline (acute necrosis, early follow-up (early scar, and late follow-up (late scar were 25 ± 17 g, 17 ± 12 g, and 15 ± 11 g, respectively. Patients were stratified in tertiles, based on infarct size, with the largest infarcts having the greatest absolute decrease in mass at early and late scar. The percent reduction of infarct mass was independent of initial infarct size. There was an 8 g or 32% decrease in infarct mass between acute necrosis and early scar (p  Conclusions Infarct healing is a continuous process after reperfusion for STEMI, with greatest reduction in infarct size in the first few months. The dynamic nature of infarct healing through the first year after STEMI indicates that decisions based on infarct size, and interventions to reduce infarct size, must take into consideration the time frame of measurement.

    Full Text Available Aim: the impact of atherogenic index of plasma (AIP, calculated as logarithmic of triglyceride:HDL ratio (log10.[TG:HDL], on major adverse cardiovascular events (MACE during acute myocardial infarction (AMI has not been fully accepted. This study aims to investigate the role of AIP in predicting major adverse cardiovascular events following AMI during intensive care in the hospital. Methods: this was a prospective cohort study. We enrolled subjects with AMI hospitalized in intensive coronary care unit at Dr. Sardjito General Hospital, Yogyakarta. The AIP was measured in fasting blood within 24 hours of hospital admission. The total cholesterol, LDL, HDL, and triglyceride (TG, were measured and AIP value was determined as log10.[TG:HDL]. Based on AIP value, subjects were allocated into low AIP (<0.24 and high AIP (≥0.24. The outcome of the study was major adverse cardiovascular events during hospitalization, i.e. multipart of all cause mortality, acute heart failure, cardiogenic shock, reinfarction, and rescucitated VT/VF. Results: among 277 subjects, the high AIP group comprised 213 subjects (77% and low AIP group comprised 64 subjects (33%. During intensive hospitalisation, 66 subjects (24% developed MACE and 20 subjects (7% developed fatal outcome (all cause mortality. The incidence of MACE tended to be higher in low AIP group, however its difference was not significant. The incidence of all cause mortality was significantly higher in low AIP group (14% than in high AIP group (5%. Multivariable analysis showed that low AIP predicted all cause mortality independently with a risk ratio 3.71 (95% CI 1.26 – 10.97, p=0.02. Conclusion: low AIP value (<0.24 is an independent predictor for all cause mortality in patients with acute myocardial infarction undergoing intensive hospitalisation.

    To investigate the protective effect of adenovirus mediated Survivin protein overexpression on acute myocardial infarction in rats. 45 acute myocardial infarction rat models were constructed by suture method and were randomly divided into sham group, model group and treatment group. The treatment group was injected with Survivin gene packed virus via ventricle. The model group was injected with equal titer of adenovirus packed empty vector. The sham group was not ligated. These rats were killed in 96 h after treatment. The levels of Survivin, Caspase-3, caspase-7 mRNA and protein in myocardial tissues were detected by real-time fluorescence quantitative PCR and Western blot. Myocardium tissue cell apoptosis were analyzed by TUNEL staining, the immunology of myocardial infarction tissue was analyzed by TTC staining. Compared with model group and sham group, the level of survivin protein in myocardium tissue of rats in treatment group was significantly increased (Pmyocardial tissue of rats in model group and treatment group were significantly increased, but the treatment group were significantly lower than those of model group (Pmyocardial infarction areas of rats in model group and treatment group were significantly higher than those of sham group, but the treatment group were significantly lower than those of model group (Pmyocardial tissue can significantly inhibit the expression of apoptosis promoting factor in myocardial tissue of acute myocardial infarction rats, reduce the apoptosis index of myocardial cells and the myocardial infarct size, which has great significance for protecting myocardial function.

    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

    Rengin etin Guven; Tolga Sinan G uven

    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.

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

    2016-01-01

    Full Text Available Aim. To study the reasons of low adherence to treatment in patients after myocardial infarction as well as methods of its correction considering the mental and emotional state of patients. Material and methods. Patients (n=115 after myocardial infarction registered in "Acute Myocardial Infarction Register» were enrolled into the study. The Moriscos-Green scale was used to determine the degree of adherence to treatment, and psycho-emotional state of patients was assessed by the Hospital Anxiety and Depression Scale (HADS. The special questionnaire was used to study the causes of poor adherence. Results. Only 45% of patients after myocardial infarction have a high commitment to the doctor's recommendations. The main reason for low adherence was forgetfulness (42%. Among other reasons were: fear of side effects (16%; lack of therapeutic effect according to patients' opinion (12%; doubts about the doctor's prescriptions (14%; a large number of prescribed drugs (12%; high cost of drugs (4%. The structure of the causes of poor adherence to treatment varied greatly depending on the psycho-emotional status. Adherence to treatment can be improved by specific physician’s actions (48.5% of patients. At the same time 14% of patients did not want to take drugs for a long time under any circumstances. Conclusion. Adherence to treatment of patients after myocardial infarction deserves attention from doctors. The personalized approach considering patient’s opinion, as well as their specific features, is essential for the development of ways to improve adherence.

    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.

    The aim of this study was to explore myocardial protection of early extracorporeal membrane oxygenation (ECMO) support for acute myocardial infarction with cardiogenic shock in pigs. 24 male pigs (34.6 ± 1.3 kg) were randomly divided into three groups-control group, drug therapy group, and ECMO group. Myocardial infarction model was created in drug therapy group and ECMO group by ligating coronary artery. When cardiogenic shock occurred, drugs were given in drug therapy group and ECMO began to work in ECMO group. The pigs were killed 24 h after cardiogenic shock. Compared with in drug therapy group, left ventricular end-diastolic pressure in ECMO group decreased significantly 6 h after ligation (P myocardial infarct size of ECMO group did not reduce significantly, but myocardial enzyme and troponin-I decreased significantly. Compared with drug therapy, ECMO improves left ventricular diastolic function, and may improve systolic function. ECMO cannot reduce myocardial infarct size without revascularization, but may have positive effects on ischemic areas by avoiding further injuring.

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.

    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.

    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

  15. Proinsulin and insulin profile in acute myocardial infarction

    International Nuclear Information System (INIS)

    Proinsulin and insulin in 104 and glucagon in 10 cases were estimated by radioimmunoassay (RIA) technique in uncomplicated cases of acute myocardial infarction (A.M.I.), matched against 44 and 5 controls respectively. Patients were divided into group A and B based on oral glucose tolerance test (G.T.T.) done on the following morning after admission. Group A comprised of 65 and group B comprised of 49 patients with normal and abnormal G.T.T. respectively. The tests were repeated prior to discharge from the hospital at the end of 6th week. The initial values of insulin and glucagon were found to be significantly raised in both the groups but came down to normal in group A whereas they remained unchanged in group B in the follow up study. Proinsulin values in group A were not significantly changed both in initial and follow up study. In group B proinsulin values were found to be significantly low both initially and in the follow up study. G.T.T. in group B remained abnormal even at the end of the 6th week. (author)

    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.

    International Nuclear Information System (INIS)

    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: 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.

    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

    @@ 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.

    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

    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.

    Hyper-homocysteinemia is a risk factor for coronary artery disease in young patients. A 32 years old female without any conventional risk factors except obesity presented with acute anterior wall myocardial infarction (MI). Her echocardiography showed anterior wall hypokinesia with moderate left ventricular dysfunction. 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

    An 84-year-old woman, who was followed up as hypertrophic obstructive cardiomyopathy (HOCM) in a local hospital, was transferred to our center because of anterior chest pain and diagnosed with acute myocardial infarction (MI). Coronary angiography showed total occlusion of the mid-left anterior descending, and flow was restored after endovascular thrombectomy. An autopsy was performed after she died on hospital day 6. At autopsy, there was no significant stenosis in this vessel and the absence of plaque rupture was confirmed. Likewise, it was unclear asymmetric hypertrophy at autopsy, it could not deny that a sigmoid deformity of the basal septum occurs in elderly patients and can mimic the asymmetric septal hypertrophy of hypertrophic cardiomyopathy. MI was thought to be caused by coronary spasm or squeezing in HOCM-like heart. Therefore, it may be necessary antithrombosis therapy in HOCM-like patients with no history of paroxysmal atrial fibrillation.

    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.

  3. Rat model for acute myocardial infarction: application to technetium-labeled glucoheptonate, tetracycline, and polyphosphate

    International Nuclear Information System (INIS)

    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

    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...

  13. "Stress" hyperglycaemia during acute myocardial infarction: an indicator of pre-existing diabetes?

    Science.gov (United States)

    Husband, D J; Alberti, K G; Julian, D G

    1983-07-23

    Hyperglycaemia occurring at admission in patients with suspected acute myocardial infarction is generally held to represent stress hyperglycaemia. 26 patients, not previously known to be diabetic, had blood glucose values greater than or equal to 10 mmol/l on admission to a coronary care unit. 16 survived for 2 months at which time a 75 g oral glucose tolerance test (OGTT) showed diabetes in 10 (63%) and impaired glucose tolerance in 1 (WHO criteria). All those with abnormal glucose tolerance at 2 months had had raised glycosylated haemoglobin (HbA1) (greater than 7.5%) on admission, indicating pre-existing diabetes. All those with a HbA1 level over 8% had abnormal glucose tolerance. 7 of the 10 who died or did not have an OGTT also had raised HbA1 at admission. An admission blood glucose greater than or equal to 10 mmol/l in patients with severe chest pain is more likely to indicate previously undiagnosed diabetes than "stress" hyperglycaemia. There is no evidence that myocardial infarction precipitates diabetes. The glycosylated haemoglobin concentration can be used to distinguish between stress hyperglycaemia and hyperglycaemia caused by diabetes.

    Treatment with intravenous streptokinase is known to restore blood flow to the ischaemic myocardium in patients with acute myocardial infarction. However, little is known about its effect on chest pain. In a retrospective cohort study, 76 patients treated with streptokinase were compared to 76...... patients not treated with streptokinase. All patients had acute myocardial infarction and less than 6 h of cardiac symptoms. Patients treated with streptokinase had a significantly lower need for nicomorphine (median 20 mg) than patients not treated with streptokinase (median 41 mg). Correspondingly......, the median duration (3.5 h) of pain was reduced significantly in patients treated with streptokinase compared to patients not treated (24 h). We conclude that intravenous streptokinase given in the acute phase of myocardial infarction is effective in reducing the duration of cardiac chest pain....

    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.

  2. Over-Expression of Catalase in Myeloid Cells Confers Acute Protection Following Myocardial Infarction

    Directory of Open Access Journals (Sweden)

    E. Bernadette Cabigas

    2014-05-01

    Full Text Available Cardiovascular disease is the leading cause of death in the United States and new treatment options are greatly needed. Oxidative stress is increased following myocardial infarction and levels of antioxidants decrease, causing imbalance that leads to dysfunction. Therapy involving catalase, the endogenous scavenger of hydrogen peroxide (H2O2, has been met with mixed results. When over-expressed in cardiomyocytes from birth, catalase improves function following injury. When expressed in the same cells in an inducible manner, catalase showed a time-dependent response with no acute benefit, but a chronic benefit due to altered remodeling. In myeloid cells, catalase over-expression reduced angiogenesis during hindlimb ischemia and prevented monocyte migration. In the present study, due to the large inflammatory response following infarction, we examined myeloid-specific catalase over-expression on post-infarct healing. We found a significant increase in catalase levels following infarction that led to a decrease in H2O2 levels, leading to improved acute function. This increase in function could be attributed to reduced infarct size and improved angiogenesis. Despite these initial improvements, there was no improvement in chronic function, likely due to increased fibrosis. These data combined with what has been previously shown underscore the need for temporal, cell-specific catalase delivery as a potential therapeutic option.

    2013-06-01

    Most recently, the possible impact of transitions to and from daylight saving time (DST) on the increased incidence of acute myocardial infarction (AMI) has been suggested. The goal of this report was to analyze independent influence of DST transitions on the incidence of AMI with simultaneous control for the confounding presence of situational triggers such as physical exertion, emotional stress, heavy meals, and sexual intercourse, as well as for other clinical factors. Detailed information was obtained from 2412 patients and included baseline characteristics, working status, exact time of AMI, possible external triggers, cardiovascular risk factors, and prehospital medication. AMI incidence on days after the DST was compared with incidence during control periods and patient characteristics, cardiovascular medication, and circumstances of AMI were evaluated to identify potential risk modifiers. Relative risks of AMI and differences in patient characteristics were expressed through incidence ratios and odds ratios, respectively, with 95% confidence intervals (CIs). Multivariate analysis was performed by using a stepwise multiple regression to assess the independent predictive significance of the characteristics of patients for the AMI occurring in the posttransitional period. The incidence ratio for AMI for the first four workdays after the spring DST transition was 1.29 (95% CI: 1.09-1.49) and the excess was particularly prominent on Monday. In autumn, the incidence ratio for AMI for this 4-d period was 1.44 (95% CI: 1.19-1.69), with peaks on Tuesday and Thursday. The independent predictors for AMI during this period in spring were male sex (p = 0.03) and nonengagement in physical activity (p = 0.02) and there was a trend for the lower risk of incident among those taking calcium antagonists (p = 0.07). In autumn, the predictors were female sex (p = 0.04), current employment (p = 0.006), not taking β-blocker (p = 0.03), and nonengagement in physical activity (p

    Objective.To examine the procoagulant effects of thrombolytic agent on hemostasis and study the role of hemostatic markers as predictors of clinical outcomes.Methods.In the present study,eighteen patients with acute myocardial infarction(AMI) received 1.5 or 2.0 million U nonspecific urokinase(UK),or 70~80 mg fibrin specific recombinant tissue plasminogen activator(rt PA)and did not use heparin until 8 hours after intravenous injection of the above agents.Eight patients with AMI and without thrombolytic therapy were enrolled as controls.Coagulant and thrombolytic activity markers included thrombin antithrombin Ⅲ complex (TAT),D dimer,fibrinogen (Fg),FMPV/Amax.All markers were determined before,immediately,1,2,4 and 8 hours after the administration of thrombolytic agents respectively. Results.Molecular marker of thrombin generation- - TAT showed an activated coagulant state immediately after thrombolytic therapy.Level of TAT showed no significant changes between every two observed phases in controls.However,level of TAT increased significantly from 4.95± 1.75μ g/L ( 4.63± 1.37μ g/L) to 14.71± 3.31μ g/L ( 14.25± 2.53μ g/L) before and immediately after administration of thrombolytic agents UK(or rt PA).There was significant difference between level of serum TAT of patients with and without thrombolytic therapy (P< 0.05).Patients achieving clinical reperfusion had lower TAT level than those failing in thrombolytic therapy,and higher FMPV/Amax level than controls.D dimer,a surrogate of thrombolytic activity increased markedly and Fg significantly declined after thrombolytic therapy(P< 0.05). Conclusions.Thrombin generation occurred in plasma in response to excess fibrinolysis induced by thrombolytic therapy.Both urokinase and rt PA had procoagulant action.This transient activation of the coagulant system might contribute to early reocclusion.These data provided the theoretical support for simultaneous administration of anticoagulant therapy with thrombolytic

    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.

    A 34-year-old female with a history of systemic lupus erythematosus (SLE) developed an acute inferior myocardial infarction while hospitalized for methicillin-resistant Staphylococcus Aureus sepsis. An emergent coronary angiography revealed an ectatic proximal left coronary artery and a huge aneurysm (37 mm × 32 mm) in the mid-portion of the right coronary artery, which had ruptured into the right atrium. A "steal phenomenon" due to significant left to right shunt resulting from the ruptured aneurysm was the cause of the myocardial infarction. Infection of the wall of the aneurysm might have contributed to the growth and the rupture in the presence of a pre-existing coronary aneurysm.

    The role of tenascin C in patients with acute myocardial infarction and type 2 diabetes mellitus still remains disputable today. The purpose of the study is to elaborate a model for the prediction of left ventricular failure in patients with acute myocardial infarction and type 2 diabetes taking into account the level of tenascin C, as well as to evaluate the prognostic value of this indicator in the development of acute myocardial infarction. The study showed that over time the content of tenascin C decreased on the 10th-12th day in patients with acute myocardial infarction and type 2 diabetes mellitus compared to patients with acute myocardial infarction without type 2 diabetes. The results demonstrated predictive properties of tenascin C in the development of acute myocardial infarction in patients with type 2 diabetes. The study allowed the authors to elaborate a model for the prognosis of acute left ventricular failure, taking into account the level of tenascin C. Combination of tenascin C dynamics and frequency of respiratory movements increased prognostic properties of the model, particularly its sensitivity (84%) and specificity (83%). Thus, the study proved the expediency of the model based on tenascin C indices for prognosis of acute left ventricular failure in patients with acute myocardial infarction and type 2 diabetes mellitus.

    Many observational studies showed hogh-density lipoprotein cholesterol (HDL-C) is a strong inverse predictor of cardiovascular (CV) outcome. However, recent large clinical trials evaluating therapies to raise HDL-C level in those already on statin therapy have been discouraging. This complexity is not well-known.A total of 28,357 acute myocardial infarction (AMI) patients were enrolled in the Korea Acute Myocardial Infarction Registry (KAMIR), which was a prospective, multicenter, nationwide, web-based database of AMI in Korea. From this registry, we evaluated 3574 patients with AMI who have follow-up HDL-C level to investigate its association with clinical outcomes. The primary endpoint was the relationship between follow-up change in HDL-C and a 12-month composite of major adverse cardiac events (MACEs).Patients with initial HDL-C ≥ 40 mg/dL showed significantly lower rates of 12-month MACEs, especially cardiac and all-cause mortalities (P < 0.001). When patients were stratified into 4 groups according to the change of HDL-C, patients with decreasing HDL-C showed significantly higher rates of 12-month MACEs as comparable with patients with increasing HLD-C. A multivariate analysis indicated that HDL-C level was a significant predictor of CV events (hazard ratio, 1.38; 95% confidence interval, 1.12-1.71) after correcting for confounding variables.The follow-up change in HDL-C level was significantly related with CV outcomes in patients with AMI.

    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

    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.)

    Objective:To study the myocardium-protective effect of ticagrelor combined with emergency PCI treatment of acute myocardial infarction and explore the possible molecular mechanisms. Methods:A total of 84 patients with acute myocardial infarction who received emergency PCI treatment in our hospital from February 2014 to October 2015 were selected for study and randomly divided into and ticagrelor group and clopidogrel group that received different perioperative anti-platelet therapy. Degree of myocardial cell damage, cardiac pump function as well as blood perfusion and platelet aggregation function of two groups were evaluated. Results:Before as well as 10 min and 24 h after PCI, plasma CK-MB and cTnI levels as well as maximum platelet aggregation rate and P2Y12 reaction unit of ticagrelor group were significantly lower than those of clopidogrel group, and ADP-way platelet inhibition rate were higher than those of clopidogrel group; after PCI, TIMI blood flow grade, TMP myocardial perfusion grade and LVEF of ticagrelor group were significantly higher than those of clopidogrel group, LVEDD was significantly lower than that of clopidogrel group and the number of cases with no reflow/slow flow was less than that of clopidogrel group. Conclusions:The myocardium-protective effect of ticagrelor combined with emergency PCI treatment of acute myocardial infarction is better than that of clopidogrel, and ticagrelor can enhance the anti-platelet aggregation effect to exert myocardium-protective effect.

    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)

    Many research groups are currently investigating new treatment modalities for myocardial infarction. Numerous aspects need to be considered for the clinical application of these therapies, such as low cell integration and engraftment rates of cell injection techniques. Decellularized tissues are considered good materials for promoting regeneration of traumatic tissues. The properties of the decellularized tissues are sustained after processing to powder form. In this study, we examined the use of decellularized tissue powder in a rat model of acute myocardial infarction. The decellularized tissue powders, especially liver powder, promoted cell integration and neovascularization both in vitro and in vivo. Decellularized liver powder induced neovascularization in the infarct area, resulting in the suppression of myocardial necrosis. The results of this study suggest that decellularized liver powder has good potential for application as a blood supply material for the treatment of myocardial infarction.

    Not every axillary dermatitis is caused by an allergy against corresponding cosmetics (deodorants or anti-perspirants). This is shown in a 24-year-old man with an acute contact dermatitis in the left axilla. Sensitization probably developed against mercury salts due to the regular use of thermometers which were kept in a disinfecting solution containing phenylmercuric borate. The patient was in two hospitals for a check up before heart surgery and temperature was regularly measured in the left axilla. In both clincis phenylmercuric borate was used for desinfection of the thermometers. The sensitivity was proofed by positive patch tests.

    Full Text Available Microvascular disease is a prominent feature of systemic sclerosis (SSc and leads to Raynaud's phenomenon, pulmonary arterial hypertension, and scleroderma renal crisis. The presence of macrovascular disease is less well established, and, in particular, it is not known whether the prevalence of coronary heart disease in SSc is increased. We report a case of SSc who presented with evolved myocardial infarction whose angiogram revealed tortuous coronaries and peripheral arteries. Regional wall motion abnormality was not demonstrated on echocardiography. The microvascular dysfunction and vasospasm of coronaries were responsible for the myocardial infarction.

    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

    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.

    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

    Full Text Available Abstract Background The long-term prognosis of diabetic patients with acute myocardial infarction (AMI treated by acute revascularization is uncertain, and the optimal pharmacotherapy for such cases has not been fully evaluated. Methods To elucidate the long-term prognosis and prognostic factors in diabetic patients with AMI, a prospective, cohort study involving 3021 consecutive AMI patients was conducted. All patients discharged alive from hospital were followed to monitor their prognosis every year. The primary endpoint of the study was all-cause mortality, and the secondary endpoint was the occurrence of major cardiovascular events. To elucidate the effect of various factors on the long-term prognosis of AMI patients with diabetes, the patients were divided into two groups matched by propensity scores and analyzed retrospectively. Results Diabetes was diagnosed in 1102 patients (36.5%. During the index hospitalization, coronary angioplasty and coronary thrombolysis were performed in 58.1% and 16.3% of patients, respectively. In-hospital mortality of diabetic patients with AMI was comparable to that of non-diabetic AMI patients (9.2% and 9.3%, respectively. In total, 2736 patients (90.6% were discharged alive and followed for a median of 4.2 years (follow-up rate, 96.0%. The long-term survival rate was worse in the diabetic group than in the non-diabetic group, but not significantly different (hazard ratio, 1.20 [0.97-1.49], p = 0.09. On the other hand, AMI patients with diabetes showed a significantly higher incidence of cardiovascular events than the non-diabetic group (1.40 [1.20-1.64], p Conclusions Although diabetic patients with AMI have more frequent adverse events than non-diabetic patients with AMI, the present results suggest that acute revascularization and standard therapy with aspirin and RAS inhibitors may improve their prognosis.

    The national LUCKY registry (Luxembourg Acute Myocardial Infarction Registry) confirms for Luxembourg that transfer of patients with acute myocardial infarction for primary percutaneous coronary intervention (PCI) is very effective. However, while mortality is low after PCI, a third of the patients with acute myocardial infarction develop severe left ventricular dysfunction. This may in part be explained by relatively long time delays between onset of symptoms and opening of the infarct-related artery, despite short distances between hospitals (time is myocardium). Surprisingly, in comparison with men, women are younger, have a higher body mass index and receive less evidence-based therapies such as statins before and after myocardial infarction. In conclusion, PCI has substantially improved the treatment of acute myocardial infarction in Luxembourg, but all actors including the patient have to keep efforts high to minimize time delays.

    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. PMID:25648770

    Full Text Available Abstract Background Acute myocardial infarction (AMI in young women represent an extreme phenotype associated with a higher mortality compared with similarly aged men. Prothrombotic gene variants could play a role as risk factors for AMI at young age. Methods We studied Factor V Leiden, FII G20210A, MTHFR C677T and beta-fibrinogen -455G>A variants by real-time PCR in 955 young AMI (362 females and in 698 AMI (245 females patients. The data were compared to those obtained in 909 unrelated subjects (458 females from the general population of the same geographical area (southern Italy. Results In young AMI females, the allelic frequency of either FV Leiden and of FII G20210A was significantly higher versus the general population (O.R.: 3.67 for FV Leiden and O.R.: 3.84 for FII G20210A; p Discussion and conclusion Our data confirm that young AMI in females is a peculiar phenotype with specific risk factors as the increased plasma procoagulant activity of FV and FII. On the contrary, the homozygous state for the 677T MTHFR variant may cause increased levels of homocysteine and/or an altered folate status and thus an increased risk for AMI, particularly in males. The knowledge of such risk factors (that may be easily identified by molecular analysis may help to improve prevention strategies for acute coronary diseases in specific risk-group subjects.

    2000-07-01

    The progressive aging of the population is associated with an increase in the proportion of very old patients (greater than 75 years) hospitalized with acute myocardial infarction. The lack of evidence regarding the efficacy of most therapeutic interventions for acute myocardial infarction in these patients is leading to a significant degree of uncertainty in the cardiology community with respect to their optimal management. When aggressive treatment (defined as a therapeutic strategy designed to obtain and maintain a patent infarct-related coronary artery at an early moment) of acute myocardial infarction is considered in very old patients, three main questions should be addressed: why should we treat? Whom should we treat? And how should we treat? To answer these questions, the authors reviewed the data available in the literature as well as new data from the PPRIMM75 (Pronóstico del PRimer Infarto de Miocardio en Mayores de 75 aÃ+/-os) Registry, a large, prospective database of patients aged 75 years or older, admitted to a single coronary care unit in Madrid, Spain, for their first acute myocardial infarction during the last decade.

    Background Acute myocardial infarction (AMI) is the leading cause of morbidity and disability among Iranian population.Pre-hospital delay is an important cause of increasing early and also late mortality in AMI.Thus the aim of the present study was to identify the factors influencing pre-hospital delay among patients with AMI in Iran.Methods Between August 2010 and May 2011,a cross-sectional and single-center survey was conducted on 162 consecutive patients with ST-elevation myocardial infarction (STEMI) admitted to Cardiac Care Unit (CCU) of Dr.Heshmat Hospital,Rasht.All patients were interviewed by the third author within 7 days after admission by using a four-part questionnaire including socio-demographic,clinical,situational and cognitive factors.Data were analyzed by descriptive and Logistic regression model at P < 0.05 using SPSS 16.Results Mean age was (60.11±12.29) years in all patients.Majority of patients (65.4%) were male.The median of pre-hospital delay was 2 hours,with a mean delay of 7.4 hours (±16.25 hours).Regression analysis showed that admission in weekend (P <0.04,OR=1.033,95% Cl=1.187-2.006) and misinterpretation of symptoms as cardiac origin (P <0.002,OR=1.986,95% Cl=1.254-3.155) and perceiving symptoms to not be so serious (P <0.003,OR=3.264,95%Cl=1.492-7.142) were factors influencing pre-hospital delay > 2 hours.Conclusions Our findings highlight the importance of cognitive factors on decision-making process and pre-hospital delays.Health care providers can educate the public on AMI to enable them recognize the signs and symptoms of AMI correctly and realize the benefits of early treatment.

    2015-04-01

    We present segments from a 24-hour 12-lead digital Holter recording in a 48-year-old man demonstrating transient ST elevations in the inferior leads that triggered sustained ventricular tachycardia/ventricular fibrillation (VT/VF) requiring cardioversion. The onset of VT was preceded by a gradual increase in the ST with marked QRS broadening that lacked distinction between the end of the QRS and the beginning of the ST (QRS-ST-T "triangulation"), and shortening of the QT interval not caused by an increased heart rate. This is a relatively rare documentation of the mechanisms immediately triggering sustained ventricular arrhythmias during acute myocardial ischemia obtained with 12-lead ECG.

    We report a very rare case of a 47-year-old man who had coronary spasm that resulted in a silent myocardial infarction, a ruptured myocardial wall, and a nonruptured left ventricular pseudoaneurysm. The patient presented with a 6-month history of dyspnea on exertion, without evidence of fixed coronary artery stenosis. Coronary angiography showed severe coronary spasm of the left anterior descending and left circumflex arteries; the spasm was relieved promptly by nitroglycerin. Echocardiography and left ventricular angiography revealed the large left ventricular pseudoaneurysm posterolateral to the left ventricle. We performed surgical resection of the pseudoaneurysm and patch repair of the ruptured left ventricular wall, with excellent results. We present this case because of the highly unusual sequence of events. Early surgical intervention resulted in the patient's recovery.

  18. Does thrombolytic therapy harm or help in ST elevation myocardial infarction (STEMI caused by the spontaneous coronary dissection?

    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.

    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.

  4. 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

    The role of platelets in the pathogenesis of ST-elevation myocardial infarction (STEMI) has been substantiated by studies that demonstrated significant clinical benefits associated with antiplatelet therapy. Initial platelet counts in Acute Myocardial Infarction (AMI) may be a useful adjunct for identifying those patients who may or may not respond to fibrinolytic agents. Patient with acute STEMI has variable level of platelet count and with higher platelet count have poor in hospital outcome. There are many predictors of poor outcome in Acute Myocardial Infarction (AMI) like cardiac biomarkers (Troponin I, Troponin T and CK-MB), C-Reactive Protien (CRP) and WBC (White Blood Cell) counts. Platelet count on presentation of STEMI is one of them. Higher platelet count is associated with higher rate of adverse clinical outcome in ST-Elevation Myocardial Infarction (STEMI), like heart failure, arrhythmia, re-infarction & death. So, categorization of patient with STEMI on the basis of platelet counts may be helpful for risk stratification and management of these patients.

  8. 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

    Doron Aronson

    Full Text Available BACKGROUND: Elevated serum phosphorus levels have been linked with cardiovascular disease and mortality with conflicting results, especially in the presence of normal renal function. METHODS: We studied the association between serum phosphorus levels and clinical outcomes in 1663 patients with acute myocardial infarction (AMI. Patients were categorized into 4 groups based on serum phosphorus levels (4.50 mg/dL. Cox proportional-hazards models were used to examine the association between serum phosphorus and clinical outcomes after adjustment for potential confounders. RESULTS: The mean follow up was 45 months. The lowest mortality occurred in patients with serum phosphorus between 2.5-3.5 mg/dL, with a multivariable-adjusted hazard ratio of 1.24 (95% CI 0.85-1.80, 1.35 (95% CI 1.05-1.74, and 1.75 (95% CI 1.27-2.40 in patients with serum phosphorus of 4.50 mg/dL, respectively. Higher phosphorus levels were also associated with increased risk of heart failure, but not the risk of myocardial infarction or stroke. The effect of elevated phosphorus was more pronounced in patients with chronic kidney disease (CKD. The hazard ratio for mortality in patients with serum phosphorus >4.5 mg/dL compared to patients with serum phosphorus 2.50-3.50 mg/dL was 2.34 (95% CI 1.55-3.54 with CKD and 1.53 (95% CI 0.87-2.69 without CKD. CONCLUSION: We found a graded, independent association between serum phosphorus and all-cause mortality and heart failure in patients after AMI. The risk for mortality appears to increase with serum phosphorus levels within the normal range and is more prominent in the presence of CKD.

    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 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.

    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.

  1. Role of adenosine as adjunctive therapy in acute myocardial infarction.

    Science.gov (United States)

    Forman, Mervyn B; Stone, Gregg W; Jackson, Edwin K

    2006-01-01

    Although early reperfusion and maintained patency is the mainstay therapy for ST elevation myocardial infarction, experimental studies demonstrate that reperfusion per se induces deleterious effects on viable ischemic cells. Thus "myocardial reperfusion injury" may compromise the full potential of reperfusion therapy and may account for unfavorable outcomes in high-risk patients. Although the mechanisms of reperfusion injury are complex and multifactorial, neutrophil-mediated microvascular injury resulting in a progressive decrease in blood flow ("no-reflow" phenomenon) likely plays an important role. Adenosine is an endogenous nucleoside found in large quantities in myocardial and endothelial cells. It activates four well-characterized receptors producing various physiological effects that attenuate many of the proposed mechanisms of reperfusion injury. The cardio-protective effects of adenosine are supported by its role as a mediator of pre- and post-conditioning. In experimental models, administration of adenosine in the peri-reperfusion period results in a marked reduction in infarct size and improvement in ventricular function. The cardioprotective effects in the canine model have a narrow time window with the drug losing its effect following three hours of ischemia. Several small clinical studies have demonstrated that administration of adenosine with reperfusion therapy reduces infarct size and improves ventricular function. In the larger AMISTAD and AMISTAD II trials a 3-h infusion of adenosine as an adjunct to reperfusion resulted in a striking reduction in infarct size (55-65%). Post hoc analysis of AMISTAD II showed that this was associated with significantly improved early and late mortality in patients treated within 3.17 h of symptoms. An intravenous infusion of adenosine for 3 h should be considered as adjunctive therapy in high risk-patients undergoing reperfusion therapy. PMID:16961725

    Thrombolysis is proposed for the acute treatment of cerebral infarction as it is able to recanalize occluded arteries and thus potentially restore normal perfusion of the cerebral parenchyma, but the results concerning the efficacy of this treatment are still inconclusive. However, it has been fully demonstrated that thrombolytic treatment, leads to a significant reduction in mortality, in patients with acute myocardial infarction. Data from all of the pilot studies using SK or tPA treatment in acute stroke are described in this review, which underlines the incidence of hemorrhagic transformation (hemorrhagic infart and parenchymal hematoma) and its possible correlation to clinical worsening. Pharmacological, experimental and clinical studies encourage the carrying out of large-scale clinical trials using thrombolytics in patients with acute cerebral infarction. Significant data relating to ongoing controlled clinical trials will be available in the near future; only after the analysis of these results will it be possible to confirm the efficacy of thrombolytics in acute stroke.

    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.

    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.

    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.

    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.

    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. Conclusion: We concluded that mortality in first year after MI has been significantly reduced because of therapies including thrombolysis and ß-blockers

    Angelo Modica MD, PhD

    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.

    1976-03-01

    In 20 patients with acute myocardial infarction hemodynamic controls were performed after digitalisation and following i.v. injection of 0,4 mg of Prindolol. Circulatory changes were most pronounced 5-15 min after Prindolol injection and consisted of decrease in heart rate of 7%, mean arterial blood pressure of 6%, cardiac output of 10,5%, stroke volume index of 5,1% and left ventricular work of 18%. An increase of pulmonary wedge pressure of 17%, pulmonary pressure of 9%, mean right atrial pressure of 16% and peripheral arterial resistance of 6% were calculated. In 5 cases a favourable effect on extrasystoles and in 2 cases on sinus tachycardia were observed. Not infrequently, during the initial phase of acute myocardial infarction, a hyperadrenergic state may be noted. Prindolol may be indicated, when circulatory changes or arrhythmias are suspect to be the result of this hyperadrenergic stimulation. A simultaneous digitalisation may inhibit a more intensive cardiodepression. PMID:57564

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

    Directory of Open Access Journals (Sweden)

    C.S. Thejanandan Reddy

    2013-07-01

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

    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

    Several biologic and clinical factors contribute to the increased 30-day mortality and re-infarction rate in women with ST-segment elevation myocardial infarction (STEMI). Sex differences in cardiac hemodynamic parameters such as pulmonary capillary wedge pressure (PCWP) have not been examined and might play an important role. The objectives of the present study were to examine whether female sex is an independent determinant of PCWP during acute STEMI and whether an elevated PCWP contributes to all-cause 30-day mortality and re-infarction in women. The clinical, angiographic, and hemodynamic features of 470 consecutive patients with STEMI (n = 135 women) undergoing emergency coronary angiography with right-side heart catheterization were evaluated with respect to sex. Women had an elevated PCWP (20 ± 8 vs 16 ± 7 mm Hg, p infarct size (β = 0.001, 95% CI 0.001 to 0.002, p ≤0.001) were independent predictors of an elevated PCWP. Female sex exerted a minor independent effect on 30-day mortality and re-infarction (odds ratio 2.36, 95% CI 1.25 to 4.46, p = 0.008). However, once PCWP was entered into the mediation model, sex was no longer significant, suggesting that the effect of sex on the post-STEMI outcomes is potentially mediated through PCWP (odds ratio 1.07, 95% CI 1.02 to 1.12, p = 0.011). In conclusion, during acute STEMI, women have greater left ventricular filling pressures compared with men, independent of age, hypertension, and infarct size. The biologic explanation for this difference requires additional investigation, although it does not appear to contribute to the increased 30-day mortality and re-infarction rate observed in women.

    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.

    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.
