Do results from major clinical trials indicate a change in management in the acute phase of myocardial infarction?

Abstract

Since introduction of modern Coronary Care Units, hospital mortality has been reduced by about 50%. This is most likely due to a number of treatments that today are well established. Those include detection and treatment of serious arrhythmias with antiarrhythmic agents and electrical conversion, and more aggressive early treatment of congestive heart failure, of chest pain, and of atrioventricular (AV) block and bradyarrhythmias. The new goals in early management of suspected acute myocardial infarction must aim at prevention and limitation of ischemic damage. The use of beta-blockers has been widely studied. Data from 27 randomized trials with a total of about 27,000 patients have convincingly shown that early beta-blockade reduces mortality, prevents and limits infarct development and arrhythmias, and reduces infarct complications. Three large trials, the Göteborg and MIAMI Trials on metoprolol and the ISIS Trial on atenolol, have demonstrated significant beneficial effects and good tolerance. Thrombolytic therapy in patients with signs of acute myocardial infarction, mainly streptokinase, has demonstrated significant reduction of short-term mortality. The large Italian GISSI Trial, including almost 12,000 patients, showed v...Continue Reading

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.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias 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.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

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.
