在没有左心衰竭的心梗病人中,钙的拮抗药异搏停(Verapamil)能减少心肌梗塞面积近3%,同时也能减少心房压力。54名未并发心源性休克或左室衰竭的急性心肌梗塞的病人被随意指定为在症状出现后8小时内接受静脉注射异搏定(5~10mg/h连续两天)或是不接受特殊治疗。这两组病人在年龄、梗塞面积、入院时心肌酶水平和从心肌梗塞发作到治疗介入的时间间隔上都近似。治疗组肌酸激酶(ck)的峰值和肌酸
Verapamil, an antagonist of calcium, can reduce myocardial infarct size by nearly 3% and can also reduce atrial pressure in myocardial infarction patients without left ventricular failure. Fifty-four patients with acute myocardial infarction who did not develop cardiogenic shock or left ventricular failure were arbitrarily assigned to receive intravenous verapamil (5 to 10 mg / h for two consecutive days) within 8 hours of symptom onset or to receive no special treatment. The two groups of patients were similar in terms of age, infarct size, level of myocardial enzymes on admission, and interval from onset of myocardial infarction to treatment intervention. The peak of creatine kinase (ck) and creatine in the treatment group
