Abstract:【Objective】To explore the influencing factors of disease progression and repeated hospitalization in patients with coronary heart disease(CHD),so as to provide basis for clinical diagnosis and treatment.【Methods】Clinical evaluation and Gensini score of coronary angiography were used to comprehensively analyze the clinical and coronary angiography data of patients with coronary heart disease who had been hospitalized for two consecutive unplanned return visits.The patients were divided into progressive group(116 cases)and nonprogressive group(200 cases),and the average age of the two groups were 61.23±10.32 years and 60.06±10.06 years,respectively.【Results】After the first myocardial infarction,22 patients(6.96%)were admitted to the hospital for the second time due to recurrent acute myocardial infarction;there were significant differences in the course of diabetes,the severity of three vessel disease(Gensini score),the presence or absence of diffuse vessels,complete occlusion and stent placement between the two groups(P<0.05).Compared with nonprogressive group,progressive group had longer duration of diabetes,severe changes in vascular disease and higher triglyceride levels,with a higher ratio of coronary artery occlusion,diffuse lesions and stent placement(P<0.05).There was no statistically significant difference in gender,age,course of hypertension,low-density lipoprotein cholesterol level,stent stenosis,thrombosis,calcification,diameter and length of stent placement,elective surgery and taking drugs according to doctor’s advice between the two groups(P>0.05).Multivariate logistic regression analysis showed that duration of diabetes mellitus and diffuse coronary artery disease were independent risk factors for disease progression and repeated hospitalization in patients with coronary heart disease(P<0.05).【Conclusion】Active control of blood glucose and effective control of the course of diabetes can slow down the process of coronary artery disease,and early intervention of diffuse coronary artery disease can reduce repeated hospitalization.
