Abstract

Myocardial revascularisation is now an integral part of the treatment of unstable angina. Trials comparing the efficacy of coronary surgery and medical therapy date back to the end of the 1970s. They showed a clear benefit of revascularisation on functional status but a less pronounced effect on survival. Thus, at 10 years, half of the patients in the Veterans Administration series initially treated medically, underwent surgery; however the initial therapeutic choice was not a significant prognostic factor except in patients with triple vessel disease and those with left ventricular dysfunction whose survival was better when treated surgically. In the last 10 years, coronary angioplasty has become increasingly important in the treatment of unstable angina. The short-term results are very encouraging although complications are more common during the phase of clinical instability than when symptoms have been managed. The addition of thrombolytics to the conventional heparin and aspirin treatment during angioplasty seems to be potentially harmful rather than beneficial. However, new antithrombotic agents (platelets antiaggregants such as antiglycoprotein IIB-IIIA antibodies or direct inhibitors of thrombin such as hirudin or hirul...Continue Reading

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.
