摘要
目的:探讨冠状动脉造影对伴有不同冠心病危险因素不典型心绞痛患者的临床价值。方法:130例不典型心绞痛患者,根据伴有冠心病危险因素不同分为三组:A组36例,无危险因素:B组52例,含1～2个危险因素;C组42例,含3个或以上的危险因素。全部患者均行冠状动脉造影,血管狭窄为血管内径狭窄≥50％。结果:冠状动脉狭窄共48例(37％),其中男40例,占男性患者的53％(40/76),女8例,占女性患者的15％(8/54),男女间差异显著(P<0.001)。根据危险因素不同,A组有2例(4％)血管狭窄、B组14例(27％)、C组32例(76％),各组间差异显著(P<0.001)。32例糖尿病患者有21例(65％)出现冠状动脉狭窄,其中2～3支病变16例(76％)。结论:随冠心病危险因素的增多,不典型心绞痛患者血管狭窄的发生率增加,伴糖尿病患者血管狭窄发生率更高,且多为多支血管病变。
To evaluate the clinical value of coronary angiography in atypical angina. Method: 130 cases of atypical angina were allocated into 3 groups according to the risk factors, 36 cases with no risk factors in group A, 52 cases with 1-2 risk factors in group B, 42 cases with 3 or more risk factors in group C. All patients were examined with angiography, artery stenosis was defined as reduction of diameter> 50%. Result: There were 48 cases of patients with significant vascular lesions. 2(4%) of 36 cases be revealed significant vascular lesions in group A, 14(27%) of 52 cases in group B, and 32(76%) of 42 cases in group C. The significant lesions were much more in male patients (40/76) than in female patients (8/54) (P <0.001). There are 21 cases (65%) with stenosis in 32 patients accompanied with diabetes. Conclusions: The incident rate of stenosis is more and more along with more risk factors, especially in diabetic patients.
