不稳定型心绞痛危险性分度的临床研究

目的 探讨不稳定型心绞痛（ＵＡ）的临床表现与冠状动脉病变形态学特性及近期预后的关系。方法 根据Ｂｒａｕｎｗａｌｄ分极积分标准确定ＵＡ患者的临床分级及积分，并将９６例ＵＡ患者分为Ａ（积分〉３，ｎ＝１８）、Ｂ（积分≤３，ｎ＝１５）两组，对照分析两组患者冠状动脉造影结果、住院４周内心脏事件发生率及病死率。结果 ①冠状动脉造影结果分析显示：冠状动脉复杂性病变（偏心性狭窄或伴有溃疡、弥温性不规则血栓形成及完

CLINICAL STUDY OF THE SEVERITY OF UNSTABLE ANGINA

Objective To investigate the relation between clinical presentation and coronary morphology as well as acutein- hospital prognosis in patients with unstable angina (UA). Methods The UA score was obtained on basis of the clinicalclassification by Brraunwald, and 96 patients with UA were divided into two groups according to their clinical classificationand scoring of UA. They were Group A (UA scores>3, n = 81) and Group B (UA scores≤3, n = 15). Comparative analysiswas carried out about their angiogrphic findings and the incidence of cardiac events as well as mortality within 4 weeks duringtheir hospitalization. Results Coronary morphology indicated that the patients of Group A had a significantly higher lesioncompleity score (asymmetric luminal narrowing with irregular borders including lesion ulceration or diffuse irregularities, aswell as intracoronary thrombus and total occlusion) than did those in Group B (2. 458 ± 1.14 vs 1. 444 ± 0.88, P< 0.05).The incidence of cardiac events within 4 weeks was higher in Group A than those in Group B (23.5 % vs 6.7 %, P > 0.05).Conclusion The UA score previously presented has significance value in predicting the lesion complexity of ischemia - ralatedvesel and acute in- hospital prognosis in patients with UA.
