Beta-blockers in chronic treatment after acute myocardial infarction.

Journal of Cardiovascular Pharmacology

Abstract

Postinfarction treatment trials have demonstrated that beta-blockers are beneficial after myocardial infarction (MI), significantly reducing postinfarction cardiac mortality and nonfatal reinfarction, aside from bringing about an improved quality of life. Such cardioprotective action is probably mediated by both antiarrhythmic and anti-ischemic effects of these drugs. Beta-Blockers without ISA seem to be more effective in reducing cardiac mortality than those with ISA, which is probably due to their different effects on heart rate. Patients deriving major benefit from beta-blocker therapy after MI should be "high risk," elderly, and, perhaps, hypertensive patients. The suitable duration of postinfarction beta-blocker therapy is unknown: results from recent long-term trials speak in favor of continuous postinfarction beta-blocker therapy.

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.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
