不稳定性心绞痛冠状动脉病变与患者临床表现的相关性

４８例不稳定性心绞痛（ＵＰＡ）患者冠状动脉造影显示７４处有意义的冠状动脉狭窄（直径＜５０％），以前降支病变最常见。ＵＰＡ患者绝大多数（４５／４８、９３．７％）有明显冠状动脉病变，随年龄增长冠状动脉病变有增多趋势，３支病变的冠心病病程明显长于单支病变（Ｐ＜０．０５）。初发型劳累性心绞痛多数为单支病变，自发性心绞痛与恶化型劳累性心绞痛以单支、双支病变为多，混合型心绞痛以双支或３支病变为多。ＵＡ可发生冠状动脉闭塞。

The relativity between the clinical presentation of UA patients and the coronary lesions

The 74 significant coronary lesion were showed by coranary angiography in 48 unstable angina (UA) patients,in which LAD lesion was appeared much more. These results also showed that the majority of UA patients (45/48, 93.7%) have significant coronary lesion, the numbers of vessels with lesion had some relation with the age of patients,and the duration of the disease in patients with 3 vessel lesions was longer than in single vessel lesion (P<0.05). Most of the patients with initial onset exertional angina had single vessel lesion and the patients in progressive exertional angina and spotaneous angina hadalso many of single vessel and 2 vessel lesions,and put in mixed angina patients,2 vessel and 3 vessel lesion were much more, And in UA patients the occluded lesion were also occured.
