Abstract

The optimal long-term antithrombotic treatment of patients with stable coronary artery disease (CAD) and atrial fibrillation (AF) is a challenge in daily practice. We sought to determine the prevalence of hemorrhagic complications and ischaemic events depending on antithrombotic strategy in patients with stable CAD and AF. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of cardiovascular mortality, myocardial infarction and ischaemic stroke. The subsequent risks of MACCE and clinically significant bleedings requiring hospitalisation (major safety outcome) were analyzed in a propensity score-matched analysis by adjusted Cox regression models. Six hundred and six patients with high thrombotic and bleeding risks (mean age 73.4 ± 9.8 years, 25.2% female, CHA2DS2-VASc score:4.7 ± 1.5, and HAS-BLED score:3.1 ± 1.0) were included, and 127 propensity-matched pairs were analyzed. At inclusion, 172 patients (28.4%) were on oral anticoagulation (OAC) alone (75.6% on VKA and 24.4% on DOAC) and 434 patients (71.6%) on OAC + single antiplatelet therapy (SAPT) (71.9% on VKA and 28.1% on DOAC). At 5-year follow-up, MACCE rate did not significantly differ in both groups (30.9% in OAC + SAP...Continue Reading

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
