Filter by: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.
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.
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.
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.
The purpose of this study is to determine the incidence of contrast induced nephropathy and myocardial tissue reperfusion following iso-osmolar iodixanol or ipo-osmolar iopromide administration in patients with acute myocardial infarction undergoing primary PCI.
Specific Aim 1. To determine the prevalence of OSA in patients of first-time AMI in acute phase By screening patients of first-time, single-vessel disease, Killip I AMI, and successful revascularization 2. To determine the impact of CPAP treatment on the prognosis of AMI Using sham CPAP as the optimal placebo, we conduct this randomized, double-blind, placebo controlled trial to assess the 12-week CPAP effect in moderate-severe OSA patients. 3. To determine how the OSA affects patients with MI in acute and chronic phase and vice versa, which is dissected from mechanical basis and molecular basis By comparing the clinical parameters of AMI patients without OSA (AHI<5/hr), mild OSA (5 < AHI <15), moderate OSA (15<AHI<30) and severe OSA5 (AHI>30/hr), and before and after CPAP treatment, we can determine the interaction between OSA and AMI.
The main objective is to compare a fibrinolytic strategy with an interventional strategy initiated as early as possible, preferably in the pre-hospital phase, with respect to resolution of ST-segment elevation at 120 minutes after inclusion and Thrombolysis In Myocardial Infarction (TIMI) flow grade evaluated at a mandated coronary angiography 5 to 7 days after inclusion.
Statins are usually used in AMI patients due to its strong anti-lipidemic effect, pleiotropic effect and tolerable safety profiles. Generally AMI patients are prescribed many drugs concomitantly; there are some risks due to the drug interaction. Especially, statins are reported to have many drug interactions, these might influence to therapeutic prognosis and safety in AMI patients. This study is conducted to administer the non-CYP3A4 metabolized statin, pitavastatin to AMI patients over 1 year, and the results will be compared with the other results from the KAMIR study which is expected to the large scale of AMI patients using statins be enrolled. Finally, from that comparison, we will investigate the influence of the statins metabolism by CYP3A4 to the therapeutic prognosis like death, major adverse cardiac events(MACE), and major ADR of statins like CK increase, myalgia.
