Analysis of Clinical Features and Prognostic Factors of Type 2 Myocardial Infarction
Objective To analyze the clinical features of type 2 myocardial infarction(T2MI)and the risk factors affecting its poor prognosis.Methods 182 T2MI patients admitted to our hospital from March 2021 to January 2023 were selected and followed up for 1 year.According to the follow-up results,the patients were divided into death group(n=48 cases)and survival group(n=134 cases).The clinical characteristics of T2MI patients were analyzed,and the basic clinical data of the two groups were compared.Univariate and multivariate Logistic regression analysis models were used to analyze the risk factors affecting the poor prognosis of patients with T2MI.Results The majority of patients were over 50 years old,and the proportion between 70 and 80 years old reached 37.91％.The proportion of female patients was higher than that of men.Patients with a history of smoking accounted for 26.92％.Gender,body mass(BMI),diabetes mellitus,smoking history,infarct vessels,number of lesions,left ventricular end-diastolic diameter(LVEDD)and low density lipoprotein cholesterol(LDL-C),white blood cell count(WBC),hemoglobin(HB),serum creatinine(Scr),C-reactive protein(CRP)water in the death and survival groups There was no statistical significance(P＞0.05).Age,proportion of patients with arrhythmia,proportion of patients with hypertension,proportion of≥Ⅱ in heart failure grading(Killip grading)and the levels of troponin(cTn)and brain natriuretic peptide(NT-proBNP)in death group were higher than those in survival group(P＜0.05).The proportion and LVEF level of Killip grade Ⅰ were lower than those of survival group(P＜0.05).Logistic regression analysis model showed that old age,arrhythmia,hypertension,high levels of NT-proBNP and cTn were risk factors for death(P＜0.05).Conclusion Elderly and female patients accounted for a large proportion of T2MI patients,with more underlying diseases and high mortality.Old age,hypertension and high concentration of NT-proBNP and cTn are risk factors for poor prognosis of T2MI.
