【摘要】 目的 :探讨心绞痛对冠心病患者冠状动脉侧支循环形成及其预后的影响。方法 :对236例选择性冠状动脉造影的冠心病患者 ,分析既往心绞痛与冠状动脉侧支循环形成及左心室功能的关系 ,并进行12～48个月随访 ,了解其预后情况。结果 :236例中有心绞痛史168例 (A组 ) ,无心绞痛史68例 (B组 ) ,两组间不稳定型心绞痛、心肌梗死发生率差异无显著性 (P>0 05) ;A组形成侧支循环的比率显著高于B组 (P<0 01) ;A组左室射血分数 (LVEF)显著高于B组 (P<0 05) ;随访12～48个月 ,A组死亡率低于B组(P<0 05)。结论 :既往心绞痛可促进冠状动脉侧支循环的形成 ,对心功能有保护作用 ,并可减少死亡率 ,但不能减少不稳定型心绞痛和心肌梗死的发生更多还原

【Abstract】 Objective:To investigate the influences of angina pectoris on coronary collateral circulation and prognosis in patients with coronary heart disease(CHD).Methods:236CHD cases underwent selective coronary angiography.The relation of previous angina pectoris to coronary collateral circulation and left ventricular function were analyzed and prognoses of the cases were followed-up for12～48months.Results:In the236cases,there were168(71.2%)with previous angina pectoris(group A)and68(28.8%)without(group B).(1)There were no significant difference in unstable angina pectoris and myocardial infarction between group A and B;(2)Good collateral circulation was more likely to be presented in group A than that in group B(P<0.01).(3)The left ventricular ejection fraction was significantly increased in group A than that in group B(P<0.05).(4)All the patients were followed-up for12～48months,mortality of group A was lower than that in group B(P<0.05).Conclusion:In CHD petients,precious angina pectoris may have beneficial effects on coronary collateral circulation and left ventricular function and decrease the mortality but may have on beneficial effects on decreasing unstable angina pectoris and myocardial infarction.更多还原
