Active clinical trials for "Acute Coronary Syndrome"

Patients undergoing multivessel off-pump coronary bypass surgery (OPCAB) inevitably experience cumulative ischemia-reperfusion injury at myocardium. Glucose-insulin-potassium (GIK) is a potentially useful adjunct to myocardial protection. This study was designed to evaluate the effects of GIK infusion on myocardium in patients undergoing OPCAB. Patients undergoing OPCAB with acute coronary syndrome are randomly assigned to GIK or Control group. The trial is double-blind and conducted at a single center.

The goal of this clinical research study is to compare the effects of sodium bicarbonate to normal saline when used for clearing mucus blockage in patients with airway stents.

The purpose of this project is to examine the effectiveness of computed tomographic angiography (CTA) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). People who are hospitalized with this situation often require an angiogram to assess the heart and its arteries. Recent advancements in technology have enabled CTA to clearly define coronary artery anatomy with great accuracy and to guide treatment strategies in select patient populations. We are investigating that CTA may be used, as an alternative to conventional angiograms, for the risk stratification of patients with high risk NSTE-ACS. Patients eligible for the study will be high risk NSTE-ACS and awaiting an angiogram. Enrolled patients will undergo CTA prior to the angiogram. With each CTA the patient will be injected with a small dose of an X-ray dye and will be asked to lie still on the "scanning bed" for a period of 5-10 minutes.

The aim of the project is to compare the nephro-protective effects of high-dose atorvastatin and high-dose rosuvastatin on the incidence of Contrast Induced-Acute Kidney Injury in patients with non-ST-elevation acute coronary syndromes scheduled for early invasive strategy.

RADIATION PROTECT is a randomized, controlled trial of patients undergoing coronary angiography or PCI with or without a pelvic lead shield. Interventional cardiologists who will perform the procedure will wear a radiation protection cap in all procedures. It is hypothesized that routine use of the pelvic lead shield and radiation protection cap during these procedures will reduce the amount of radiation in which the interventional cardiologists get exposed.

High platelet reactivity unit (PRU) after loading dose clopidogrel in patients undergoing percutaneous coronary intervention (PCI) is related to high risk of short and long term recurrent ischemic events including stent thrombosis. The investigators hypothesize that additional loading of prasugrel in patients with high PRU after clopidogrel loading would be superior to additional loading of clopidogrel in reducing platelet reactivity and thereby result in lower risk of short term recurrent ischemic events.

To evaluate the efficasy and safety of SR25990C(loading dose:300mg, maintenance dose:75mg/day) in comparison with the standard Japanese treatment(ticlopidine) in patients with acute coronary syndrome without ST-segment elevation and planned for percutaneous coronary intervention(including stenting).

A-Phase: Evaluating patients with chest pain who are receiving approved drugs, to estimate the effectiveness of one type of blood thinner as compared to another type of blood thinner. Z-Phase: To evaluate early treatment of patients with long term chest pain (using an approved drug for 30 days, followed by an increased dose of the drug) as compared to patients (treated with diet and 4 months placebo followed by diet and approved drug) in patients who have experienced acute chest pain or heart attack.

The aim of the study is to acess the association between admission serum uric acid level and in_hospital outcomes in patients with acute coronary syndromes

Limited data have been published on the management and outcome of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) that involves the left main (LM) coronary artery. Little is known about different strategies and techniques of percutaneous revascularization and long-term outcomes of these patients. Beside scarcity of data, most studies represent outmoded experience not reflecting contemporary advances in stent technologies, with the introduction of newer generation thinner strut drug eluting stents (DES), bioresorbable polymers, and faster re-endothelization properties promoting vascular healing and endothelial repair. These advances have significantly reduced the rate of ischemic (especially thrombotic) complications in different cohorts. Whether these advances would alter the outcome of PCI that involves the LM in patients with ACS is yet to be explored. II. Objective To explore real-world PCI strategies and techniques in patients with unprotected LM coronary disease presenting with ACS To explore short- and long-term outcomes of patients of ACS with LM intervention III.
