急性冠脉综合征患者临床及冠状动脉造影分析

目的 初步探讨急性冠脉综合征患者的冠脉病变及临床特点。方法 对42例急性冠脉综合征及20例稳定型心绞痛患者的临床资料及选择性冠状动脉造影的结果进行分析。结果 急性冠脉综合征患者中 ,危险因素≥2个者占88.1% ;不稳定型心绞痛组多支病变比率占65.2% ;与稳定型心绞痛组比较 ,不稳定型心绞痛组冠状动脉狭窄程度无显著性差异(p>0.05) ,B型、C型病变的比例在急性心肌梗塞组与不稳定型心绞痛组明显增高(p<0.01)。 结论 急性冠脉综合征的致病过程 ,并不完全取决于冠脉狭窄程度 ,还与粥样斑块病理学稳定性破坏有关

Analysis of coronary angiograph and clinic character of patients with acute coronary syndrome

Objective To evaluate coronary angiographic finding and the clinic character in the patients with acute coronary syndrome. Methods 42 cases with acute coronary syndrome and 20 cases with stable angina pectoris were performed by the angiography. Results The ratio of patients with multiple-risk factors in acute coronary syndrome was 88.1%. The ratio of multi-vascular lesions in the unstable angina pectoris group was 65.2%. Compared with stable angina pectoris group, the degree of the coronary artery stenosis was no significantly different in the unstable angina pectoris (p>0.05),but the ratio of B and C type atheroma was significantly increased in the patients with acute coronary syndrome(p<0.01).Conclusion The pathogenesis of acute coronary syndrome is not only due to the degree of coronary artery narrowing, but owing to the rupture of unstable plaque.
