BACKGROUND: Inflammation is the key process underlying the clinical course of coronary artery disease (CAD). C-reactive protein (CRP) and interleukin-6 (IL-6) participate in the pathophysiology and act as biomarkers. We sought to examine whether known single nucleotide polymorphisms (SNPs) impact the progression of CAD, reflecting higher inflammatory activity. METHODS: We retrospectively evaluated coronary angiographies of patients with already established CAD who were re-investigated for stable/unstable angina after a time interval >12 months...

Oral administration of crushed ticagrelor tablets turned out to be an efficacious method that improves its pharmacokinetics and pharmacodynamics. This strategy, however, is unlikely to eliminate the drug-drug interaction in patients receiving intravenous morphine, as the impairment of the P2Y12 inhibitor absorption related to decreased propulsive motility of the gastro-intestinal tract is the most likely mechanism of interaction. Thus, we designed a pharmacokinetic and pharmacodynamic study setting the feasibility of platelet inhibition with a loading dose of ticagrelor given as crushed tablets sublingually compared with two other ticagrelor loading dose administration strategies: integral tablet given orally and crushed tablet given orally in patients with unstable angina...

BACKGROUND: Clopidogrel is a prodrug, the minority of which is converted to an active metabolite by hepatic cytochrome P450 (CYP2C19), however, most of it is metabolized to inactive substance by hepatic carboxylesterase1 (CES1). Meanwhile angiotensin-converting enzyme inhibitors (ACEIs) are mostly metabolized by CES1. We aimed to assess the impact of ACEIs on platelet inhibition by clopidogrel. METHODS: We genotyped variants CES1, CYP2C19*2 and *3 in 502 patients with acute coronary syndrome (ACS) receiving clopidogrel therapy, and analyzed the effects of ACEIs on responsiveness to clopidogrel by the vasodilator-stimulated phosphoprotein (VASP) phosphorylation assay and ADP-stimulated impedance whole blood platelet aggregation assay...

BACKGROUND: Cardiac troponin (T and I) are considered the standard markers for detection of myocardial damage and the diagnosis of acute coronary syndrome (ACS) among patients who present to an emergency department with chest pain. However, these markers can be released in other situations and may be associated with short- and long-term clinical outcomes. In this study, we examine late mortality rates among patients presenting with a suspected ACS due to an unstable coronary plaque and those patients having a non-ACS...

BACKGROUND: It is unknown how the contemporary burden of atherosclerotic cardiovascular disease (ASCVD) compares with historical trends. METHODS: As part of the Cardiovascular Health in Ambulatory Care Research Team "big data" initiative, we used information from multiple population-based databases to study 20-year temporal trends in hospitalizations and deaths from ASCVD. We calculated hospitalization rates for 6 ASCVD events (acute myocardial infarction, unstable angina, stroke, transient ischemic attack, peripheral arterial disease, and congestive heart failure) and death rates resulting from ischemic heart disease, cerebrovascular disease and circulatory and noncirculatory causes in adults aged 20-105 years in Ontario, Canada from 1994-2014 (to 2012 for deaths)...
