本文对三种冠状动脉综合征(穿壁性心肌梗塞,心内膜下心肌梗塞,心绞痛)的侧枝循环进行分析,以了解这三种冠状动脉综合征的临床—造影联系,明确局部侧枝循环是否对梗塞后的临床症状起有作用,以及明确局部侧枝循环对心绞痛患者亚极量运动试验时是否出现缺血性心电图起有作用。方法:300例在出现典型冠心病症状一年内(平均23周)作过冠状动脉造影的患者分为三个临床组:(1)穿壁性心肌梗塞组。73例,其中43例为前壁梗塞,30例为下壁梗塞。(2)心内膜下心肌梗塞组。63例,其中33例为前壁、30例为下壁心内膜下心肌梗塞;32％患者心肌梗塞时血清酶有诊断意义的升高,68％患者血清酶无明显升高。(3)单纯
Collateral circulation in three types of coronary syndromes (transmural myocardial infarction, subendocardial myocardial infarction, angina pectoris) was analyzed in this paper to understand the clinical-angiographic associations of these three coronary syndromes and to determine whether local collateral circulation is The clinical symptoms of infarction have a role, and clear the local collateral circulation in patients with angina pectoris ischemic ECG plays a role. METHODS: Three hundred patients who underwent coronary angiography in one year (mean 23 weeks) with typical coronary heart disease symptoms were divided into three clinical groups: (1) Wearing a myocardial infarction group. 73 cases, of which 43 cases of anterior wall infarction, 30 cases of inferior wall infarction. (2) subendocardial myocardial infarction group. Sixty-three cases were anterior wall and 30 cases were inferior wall subendocardial infarction. Serum enzyme in 32% patients had diagnostic significance, while 68% patients had no significant increase in serum enzyme. (3) Simple
