Prognosis of individuals with atrial fibrillation

The Canadian Journal of Cardiology

Abstract

Patients with AF have a mortality rate about twice that of age-and sex-matched individuals without AF, and a stroke rate that is about fivefold greater. Patients less than 60 years of age with lone AF have an extremely low risk of stroke. Patients less than 65 years of age who do not have diabetes, a history of hypertension, a previous TIA or stroke, or heart failure have an annual risk of stroke of about 1% per year. Unfortunately, patients older than 65 or younger patients with any of the four risk factors have an annual risk of stroke of 4% or greater. Transthoracic and transesophageal echocardiography may be able to refine the risk stratification further, but additional studies are needed to establish their role.

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.

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.
