Filter by:The purpose of this study is to determine if ticagrelor is as effective as clopidogrel in rate of onset and degree of platelet inhibition for patients with non-ST elevation of acute coronary syndrome undergoing ad hoc PCI with bivalirudin.
The investigators hypothesized that ticagrelor may enhance endothelial healing after DES implantation by increasing adenosine concentrations by the inhibition of adenosine uptake into erythrocytes, compared to clopidogrel. Thus, the investigators will evaluate the extent of endothelialization (stent strut coverage) and neointimal hyperplasia (neointimal thickness) 3 months after DES implantation by optical coherence tomography (OCT)
Evaluating safety and PK parameter of APD-791 when co-administered with aspirin and clopidogrel.
The aim of the study is to evaluate surgery-related bleeding and mortality in patients needing acute coronary artery bypass grafting with or without valve replacement during dual antiplatelet therapy with aspirin and a P2Y12 receptor blocker (Clopidogrel, Prasugrel, Ticagrelor)
Fractional flow reserve (FFR) is a test that can be performed at the time of heart catheterization. It measures the change in pressure across a narrowing in the heart artery during high flow situation, and provides reliable information about the functional severity of the narrowing. FFR measurements accurately predict whether a stent is needed, and is considered an excellent test before placement of stents to treat narrowed heart arteries. However, FFR is not used in every case because of the extra time needed and the associated device costs. Cardiac Services BC (an agency of Provincial Health Services Authority) is sponsoring this study to find out if FFR should be used in most cases (routine), rather than the current selective approach.
The investigators are attempting to determine if the response to aspirin in women is related to the level of estrogen and progesterone that a woman has.
- The purpose of this study is to determine the efficacy and safety of an evaluation strategy based on utilization of high sensitivity cardiac troponin T (hscTnT), followed by coronary computed tomography angiography (CCTA) in patients with low-intermediate risk chest pain consistent with a possible acute coronary syndrome compared to a standard of care (SOC) strategy. - Unicentric, randomized, controlled, open label clinical trial that will compare a fast strategy (hscTnT followed by CCTA) with a SOC strategy (serial ECG and cardiac biomarkers followed by stress/rest imaging study).
Aim: to verify if after the acute phase of ACS acute coronary syndrome (1-months), from 1 to 12 months the reduction of maintenance dose of prasugrel from 10 mg to 5 mg/day may reduce the bleeding events (5 mg vs 10 mg). All patients will be treated with 325 mg of aspirin followed by a maintenance dosage of 100 mg of aspirin for at least 1 year. At baseline (after 60 mg loading dose of prasugrel) and after 1 month (7 days after the randomization at 10 or 5 mg of prasugrel) all patients will undergo light transmittance aggregometry (LTA) test to evaluate residual platelet reactivity (pharmacodynamic effects).
The investigators will test if upfront dosing of Ranolazine can reduce myocardial biomarker release (CK-MB, Troponin) post percutaneous coronary intervention (PCI).
The primary objective of this study ist to test the hypothesis that ticagrelor is superior to Aspirin (ASA) fort he prevention of major cardio- and cerebrovascular events (MACCE) in patients undergoing artery bypass operation. The primary efficiacy MACCE-endpoint is the composite of cardiovascular death, myocardial infarction, recurent revascularisation, and stroke at twelve month after coronary artery bypass operation.
