Abstract

AF is the most common sustained cardiac rhythm disorder and an established risk factor for ischemic stroke. Ischemic strokes which occur in patients with AF are particularly severe and disabling. In addition, stroke recurrence is more common in patients with AF compared with those without it. Previous cerebrovascular events, age, hypertension, diabetes, and heart failure are risk factors for stroke in patients with AF. Various risk stratification schemes have been developed to quantify the risk for stroke in patients with AF. Currently, the most frequently used schemes to assess stroke risk in patients with AF are CHADS2, the ACC/AHA/ESC and American College of Chest Physicians (ACCP) schemes. Current risk scores are largely derived from risk factors identified from clinical trials and many potential risk factors have not been properly considered. Consequently, the stroke risk in many patients could be underestimated, and these patients could receive a suboptimal antithrombotic prophylaxis. There is substantial evidence for the benefit of vitamin K antagonists (VKA) in preventing stroke and reducing mortality. Novel oral anticoagulants are available for stroke prevention in patients with AF which overcome some of the difficulti...Continue Reading

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.

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.

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.

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.
