| Objectives:Retrospective analysis of the factors related to the rehospitalization of STEMI patients after emergency PCI due to MACE events,such as gender,length of stay,smoking,alcohol abuse,number of vascular lesions,laboratory examination,etc.2.MACE events and clinical significance of rehospitalization patients were studied.The relevant influencing factors of rehospitalization were obtained through data analysis,and the clinical characteristics of the rehospitalization patients were analyzed,so as to provide a basis for secondary prevention and reduction of rehospitalization rate after PCI for STEMI patients and save valuable medical resources.Methods:A total of 1580 patients with acute st-segment elevation myocardial infarction who were hospitalized in the cardiovascular disease diagnosis and treatment center of the first Bethune hospital of jilin university from January 1,2016 to December 31,2016 were collected.A total of 560 patients who met the requirements were screened according to the inclusion and exclusion criteria.560 patients were followed up by telephone to observe whether they were admitted to hospital for the first time due to MACE events within 1 year and their detailed information.Among them,76 patients(rehospitalization group)were admitted for the first time due to MACE events within 1 year after discharge,and 484 patients(non-admission group)were not admitted for MACE events.The information of inpatients was collected through the electronic medical record system,and the influence of gender,length of stay,smoking,alcohol abuse,number of vascular lesions,laboratory examination and other factors on the readmitted patients and the general clinical characteristics of the readmitted patients were analyzed retrospectively.Results:1.A total of 560 eligible patients were included in this study.There were no significant differences in alcohol addiction,mean systolic and diastolic blood pressure,type 2 diabetes mellitus,hyperlipidemia,onset to admission time,onset to IRA opening time,related infarct artery(IRA),CK-MB and LVDDD between the rehospitalization group and non-admission group(p > 0.05).There were no significant differences in creatinine,total cholesterol,low density lipoprotein,high density lipoprotein,serum albumin,serum potassium,serum sodium,serum calcium,intravenous glucose,white blood cells,platelets,neutrophils,lymphocyte and NLR between the two groups(p > 0.05).2.Univariate analysis showed statistically significant differences in gender,age,smoking index,length of stay,hypertension complications,number of vascular lesions,triglyceride,CTnI Max,LVEF,and hemoglobin between the rehospitalization group and the non-admission group(p<0.05).3.Multivariate Logistic regression analysis showed that CTnI Max,total white blood cell count,length of stay and number of vascular lesions were independent risk factors for readmission of STEMI patients after PCI,and hemoglobin was a protective factor.4.The rehospitalization rate was 13.57%(76/560),including 4.46%(25 cases),7.50%(42 cases)and 9.64%(54 cases)within 1 month,3 months and 6 months,respectively.5.According to the analysis of specific MACE events in the rehospitalization group,angina pectoris was 74%(56/76),heart failure was 18%(14/76),cardiogenic death was 7%(5/76),and arrhythmia was 1%(1/76).Conclusions:1.Age,gender,smoking index,length of stay,number of vascular lesions,hypertension,CTnI Max,LVEF,triglycerides,and hemoglobin are the relevant influencing factors for rehospitalization after PCI for STEMI patients.2.CTnI Max,Leukocyte count,length of stay,and number of vascular lesions were independent risk factors for rehospitalization after PCI for STEMI patients,and hemoglobin was the protective factor for rehospitalization.3.The peak period of rehospitalization was within 1 month after discharge;The incidence of angina pectoris was the highest among all the re-admitted patients with MACE events. |
