Abstract
In a multicentre study 711 patients were randomised to a group receiving calcium-heparin, 12 500 U, subcutaneously (360), or to a group receiving no heparin (351), beginning within 24 h of the onset of symptoms. 433 of these patients, admitted within 6 h, were given intravenous streptokinase (SK). Results were analysed for the in-hospital period. Calcium-heparin had no significant effects on the frequency of electrocardiographically documented ischaemic episodes or non-fatal reinfarction in the whole series; in the subgroup receiving SK, transient ischaemic episodes recurred in 14·2% of those treated with heparin vs 19·6% of the controls (p = 0·08). Mortality was significantly lower in the calcium-heparin treated patients, both in the overall groups (21/360 vs 35/351, p=0·03) and in the SK subgroups (10/218 vs 19/215, p=0·05). In 200 patients with first anterior myocardial infarction, it was possible to assess the effect of heparin on left ventricular mural thrombosis. On predischarge two-dimensional echocardiography, the prevalence of thrombus was significantly lower in the heparin group than in the control group (19/107 vs 34/93). Heparin also greatly reduced the incidence of thrombus formation in those who were thrombus-free on admission. Complications of heparin treatment were few.
