Abstract

Warfarin is an oral anticoagulant for treatment and prevention of venous and arterial thromboembolism. It requires regular monitoring and patient adherence to a variety of lifestyle factors that can influence its effect. Dabigatran is an oral direct thrombin-inhibitor recently approved for stroke prevention in atrial fibrillation. The primary advantages of dabigatran are freedom from monitoring, a short duration of action, and a limited number of factors influencing its effect. Primary disadvantages of dabigatran compared with warfarin are that less is known about its use, cost, and poor gastrointestinal tolerability. Clinical studies have revealed both agents to be effective, with comparable rates for major bleeding. Divergent recommendations have been offered by consensus guidelines. A patient-specific approach involving the perspectives of informed patients is most reasonable.

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 Filbrillation

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

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.

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
