Filter by:The purpose of this study is to assess the safety and efficacy of Enoxaparin and Unfractionated Heparin in St Elevation Myocardial Infarction patients undergoing primary percutaneous coronary intervention.
The purpose of this study is to investigate the effect of intravenous human recombinant erythropoietin on the reperfusion injury at primary percutaneous coronary intervention in patients with acute myocardial infarction.
This study is aimed to investigate whether treatment with Telmisartan is more effective than Candesartan in reducing the ischemic cardiovascular events in high-risk patients with cardiovascular disease.
The investigators hypothesize that patients with Acute ST Elevation Myocardial Infarction may benefit from primary angioplasty with use of a drug eluting balloon/bare metal stent combination without impairing the process of normal vascular healing and endothelial function. The goals of this study are: 1. To compare 6-month angiographic outcome after primary angioplasty using drug eluting balloon/bare metal stent combination versus drug eluting stent versus bare metal stent. 2. To compare stent apposition and stent endothelialization after primary angioplasty using drug eluting balloon/bare metal stent versus drug eluting stent versus bare metal stent. 3. To compare coronary endothelial function after primary angioplasty using drug eluting balloon/bare metal stent versus drug eluting stent versus bare metal stent.
Objective: Untreated OSA is associated with three fold risk of fetal and non-fetal cardiovascular events than control subjects in the long-term follow up. However, the prevalence rate and impact of OSA in patients with acute myocardial infarction (AMI) was not clear so far. The conflicts of studies come from variable period of AMI, heart function at enrollment, techniques used to diagnose OSA, time to revascularization, and target endpoint. Therefore, this project aimed to study the patients of first-time, Killip I-II, and post primary percutaneous coronary intervention (PCI) AMI in both and chronic phase to achieve four goals: Aim 1. To determine the prevalence rate of OSA in patients with first-time AMI The acute phase of AMI was defined as within 14 days of the onset of AMI and the chronic phase was defined as > 14 days of onset. Eligible patients were screened with polysomnography within 5th to 7th days and 6th months of AMI to determine the prevalence rate of OSA in the AMI. Patients who had AHI more than 15/hr were considered as suffering from OSA. Aim 2. To identify the clinical characteristics and risk factors in AMI patients associated with OSA Patients were followed up at clinics for five years. The baseline demographics of patients with or without OSA were compared to determine the factors associated with OSA in AMI patients. Aim 3. To study the impact of OSA on the prognosis of AMI patients after revascularizaton The primary endpoint was mortality rate and cardiac events. The secondary endpoint was left ventricular function and variables related to cardiovascular disease (CVD) and metabolic syndrome. The impact of OSA on AMI was determined by comparing primary and secondary endpoint between AMI patients with and without OSA. Aim 4. To identify the clinical and molecular factors attributing to AMI in OSA patients Factors attributing to AMI in OSA patients were determined by comparing the clinical data and mRNA expression of angiogenesis and other related genes in OSA patients with the acute phase of AMI and patients without major CVD.
Survival after invasive coronary revascularization is worse in patients with chronic kidney disease than in those without it. The investigators aimed to examine whether oral administration of nicorandil, a hybrid of nitrate and adenosine triphosphate-sensitive potassium channel opener, could improve the survival of end-stage renal disease patients with coronary artery disease by inhibiting cardiac death after coronary revascularization.
The size of a heart attack will be decreased by the use of timed balloon inflations to open the blocked blood vessel.
Diabetes mellitus is a major risk factor for the development of ischemic heart disease, and patients with diabetes mellitus have a worse outcome following an acute myocardial infarction than non-diabetic patients. Furthermore, abnormal glucose metabolism below the diagnostic threshold of diabetes mellitus is also associated with increased risk of death compared to patients with a normal glucose metabolism. The frequency of abnormal glucose metabolism in acute myocardial infarction is high, and approximately 70% of myocardial infarction patients have diabetes mellitus, newly diagnosed diabetes mellitus or impaired glucose tolerance, leaving only 30% with normal glucose metabolism. The increased mortality among patients with acute myocardial infarction and abnormal glucose metabolism seems mainly related to a higher occurrence of congestive heart failure, suggesting that an abnormal glucose metabolism may play an important role among others in endothelial dysfunction, infarct healing and overall left ventricle function. This raises the question, whether patients with acute myocardial infarction and abnormal glucose metabolism have increased frequency of micro- or macrovascular disease or both. Coronary flow velocity reserve reflects the patency of the epicardial coronary artery in combination with vasodilator capacity of the microcirculation and may therefore offer a tool for assessment of macro- and microcirculation. This study will focus on the relation between coronary flow velocity reserve estimated by transthoracal Doppler echocardiography and mortality, risk for heart failure and left ventricle function after acute myocardial infarction stratified according to glycometabolic state
The purpose of this study is to compare clopidogrel effectiveness between severe hemodynamically unstable versus stable patients with acute myocardial infarction.
The purpose of this observational study is to find characteristics and risk stratification methods for identification of subjects who have increased risk of death, especially sudden cardiac death, after acute myocardial infarction.
