Filter by:The antiplatelet agent clopidogrel is an effective drug for the prevention of thrombotic events in patients with acute coronary syndromes, and is therefore one of the most frequently prescribed drugs worldwide. Accumulating data suggest that the response to clopidogrel is characterised by significant inter-patient variability in the degree of platelet inhibition and the risk of cardiovascular events. Recent research findings have highlighted the role of genetic variations in determining antiplatelet response variability, and this has aroused interest in genotyping all thienopyridine-eligible patients in order to identify those who would be at increased risk of harm if treated with clopidogrel. This is a prospective, multicentre, randomised study enrolling consecutive patients hospitalised because of an ACS with or without ST-segment elevation. The patients are randomised to undergo or not tests for CYP2C19*2, CYP2C19*17 and ABCB1 3435 genetic variants immediately after diagnosis. The genotyping is done using a Q3 System (a compact platform that enables the classic laboratory analysis of DNA by means of real-time PCR). The Q3 has been designed as a low entry-cost, portable, point-of-care instrument for foolproof use by unskilled personnel. The patients randomised to the pharmacogenomic arm receive one of the ADP receptor antagonists (clopidogrel/prasugrel/ticagrelor) on the basis of an algorithm that consider genetic and clinical variables. The patients randomised to the standard treatment arm receive clopidogrel or prasugrel or ticagrelor on the basis of the standard of care (clinical algorithm alone). For each patient, a record is made of the occurrence of cardiovascular death, non-fatal MI, stroke, BARC-defined bleeding, and definite or probable stent thrombosis. The primary endpoint is the composite of death due to cardiovascular causes, non-fatal MI and stroke. The secondary endpoints is the occurrence of definite or probable stent thrombosis, and BARC-defined major bleeding events (types 3-5).
To evaluate the OptiScanner® for continuous glucose monitoring as a tool to optimize glucose levels in patients hospitalized for acute coronary syndromes
To investigate how platelets recover to normal function in subjects who have symptoms of a heart attack or unstable angina and who get a loading dose of prasugrel or clopidogrel for planned coronary angiography.
The purpose of this study is to evaluate whether 64-slice Computed Tomographic coronary angiography is useful for rapid diagnosis or exclusion of significant coronary artery disease in patients who present to the Emergency Department with chest pain.
