Abstract

Two hundred and thirty-one patients admitted to hospital within 5 hours of the onset of symptoms of a primary myocardial infarction were randomised into 2 groups: one received thrombolytic therapy [anisoylated plasminogen streptokinase activator complex (APSAC): 30 IU in 5 minutes] and the other was given conventional heparin therapy (5,000 IU). Heparin was given to both groups 4 hours later (500 IU/kg/day); the APSAC (N = 119) was identical with respect to age, location of infarct, Killip classification, delay before randomisation (188 +/- 62 minutes). Coronary angiography and ventriculography were performed after 3.4 +/- 1.2 days, and angioscintigraphy and myocardial scintigraphy after 19 +/- 2.5 days to determine the size of the infarct and the quality of left ventricular function. Coronary patency was much higher in the APSAC group (77%) than the heparin group (37%) (p less than 0.001). The angiographic ejection fraction was significantly greater in the thrombolytic group than in the heparin group (53 +/- 13% vs 47 +/- 12%, p less than 0.002), the difference being statistically significant in the anterior and inferior infarct subgroups. At the third week, the difference remained significant in the anterior infarct subgroup:...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.
