摘　　要：目的:探讨冠心病危险因素与冠状动脉侧枝循环形成的相关性。方法:收集冠心病患者(148例)的危险因素资料,并作冠状动脉病变Gensini积分和侧枝循环Rentrop分级,分析危险因素与冠状动脉侧枝循环形成的关系。结果:Gensini积分与侧枝循环的形成独立正相关;简单相关显示:Rentrop分级与高血压病史、收缩压、Gensini积分显著正相关;多元逐步回归显示:Rentrop分级与吸烟年数和高血压病史独立正相关。结论:冠状动脉病变程度是侧枝循环的独立影响因素,也是侧枝循环形成程度的相关因素,此外吸烟年数,高血压病促进了侧枝循环的形成。Objective：To investigate the relationship between the risk factors for coronary artery disease（CAD）and coronary collateral circulation.Methods：The clinical data were gathered in patients with CAD.The coronary artery score was recorded according to Gensini while the coronary collateral class according to Rentrop.The relationship between every variable and collateral circulation was analysed.Results： Gensini score was independently and positively related to coronary artery collateral circulation;Simple correlation showed there was a positive correlation between Rentrop class and hypertension history,Gensini score.Multiple stepwise regression analysis showed that Rentrop class was independently and positively correlated with the years of smoking and hypertension history.Conclusion： The severity of coronary stenosis predicts coronary collateral circulation and is associated with the degree of collateral circulation.In addition,the years of smoking and hypertension influence the degree of collateral circulation.
