初发型及稳定型心绞痛和急性心梗患者冠脉病变的变化

本文分析了初发型心绞痛（NAP）、无并发症的稳定型心绞痛（SAP）患者和以急性心肌梗塞（AMI）为冠心病首发症状患者的冠脉病变的严重性和范围，以探讨急性冠脉综合症与血管病变的关系。结果表明：无并发症的SAP组冠脉病变明显重于AMI与NAP组，无论是病变血管数、狭窄数、闭塞数还是病变范围，前者均重于后两组。SAP组81．3％为2支和3支血管病变，而AMI和NAP组大多数为单支血管病变（两组分别为88．2％和60．0％），各组冠心病危险因素相似。结论：急性冠脉综合症患者的冠脉病变的严重性无法预测能否发生急性冠脉综合症。

Comparison of Coronary Angiograms in Stable Angina Pectoris, New - onset Angina Pectoris, and Acute Myocardial Infarction

We studied characteristics of Coronary lesions on coronary angiograms in patients with uncomplicatedstable angina pectoris (SAP), new- onset angina pectoris (NAP), and in thae with myocardial infarction (AMI)as the first event of their cornary heart disease. The patients in SAP group had more narrowed arteries, more stenoses and occlusions, and a greater extent scores than those in AMI and NAP groups, the numbers of patients with1 - vessel disease were higher in AMI and NAP groups (88. 2% and 60% ), whereas 2 - vessle and 3 - vessel disease were more common in SAP(81. 3%) group. In conlusion, coronary atherosclerosis in patients with AMI andNAP was less extensive, the severity of coronary atherosclerosis could not predict acute coronary syndrome.
