临床研究已证明:当心绞痛发作时,前列腺素和血栓素释放入冠状循环。暂时性心肌缺血的病人,血浆前列腺素浓度升高。作者观察急性心肌梗塞病人32例(男21,女11,年龄32～83岁,平均62.7岁),于临床症状发作后的第1天和第3天,经留置中心静脉导管取上腔静脉血;第7天用22号针头穿刺取肘前静脉血,测定前列腺素。二法对比研究,结果一致。以相对稳定的前列环素(PGI_2)和血栓素A_2 Clinical studies have shown that when angina pectoris occurs, prostaglandins and thromboxanes are released into the coronary circulation. Temporary myocardial ischemia in patients with elevated plasma concentrations of prostaglandin. The authors observed 32 patients (21 males and 11 females, aged 32-83 years, mean age 62.7 years) with acute myocardial infarction. Venous venous blood was collected via indwelling central venous catheters on days 1 and 3 after the onset of clinical symptoms On the 7th day, the needle blood was taken from the front of the elbow by puncturing needle 22 and the prostaglandin was measured. Comparative study of two laws, the results are consistent. With relatively stable prostacyclin (PGI_2) and thromboxane A_2
