Objective To explore the risk factors of hemodynamic abnormalities in patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI)and to determine the contribution of these factors.Methods A total of 150 CHD patients undergoing PCI in our de-partment from January 2021 to December 2023 were prospectively recruited in the study.Accord-ing to the hemodynamic conditions,they were divided into a normal group(104 cases)and an abnor-mal group(46 cases).The causes of hemodynamic abnormalities were analyzed,and attributable risk percentage and population attributable risk percentage of these factors were estimated with logistic regression analysis.Results The hemodynamic abnormalities incidence was 30.7％.The abnormal group had significantly larger proportions of diabetes,smoking,and failures to take medication on time and in the prescribed dosage after surgery,longer stent length,and more stents,but lower level of high density lipoprotein cholesterol(HDLC)when compared with the normal group(P＜0.05,P＜0.01).Multivariate logistic regression analysis identified the following risk factors,estimated attributable risk percentage and population attributable risk percentage,diabetes,HDL-C,stent length,smoking,number of stents,and postoperative medication use in turn accord-ing to their contribution levels.Conclusion Rather complex causes lead to hemodynamic abnor-malities in CHD patients after PCI.In order of the contribution levels from high to low,they are diabetes,HDL-C,stent length,smoking,number of stents,and postoperative medication use.
