缺血性心肌病住院患者的臨床特征及其預(yù)后因素分析
[Abstract]:Objective: To investigate the clinical characteristics of inpatients with ischemic cardiomyopathy (ICM) by retrospective analysis, to explore the related factors and independent risk factors of all-cause mortality within one year, and to provide useful guidance for the prevention and treatment of ICM. The patients'general data and auxiliary examinations were collected and followed up for one year. The patients were divided into event group and non-event group according to whether all-cause deaths occurred. The data of the two groups were analyzed by single factor analysis. The factors that might affect the occurrence of ICM events were screened out. P? Result: 1. Through screening, 363 patients, including 224 males and 139 females, met the enrollment criteria. The 1-year survival rate of the above patients was followed up, including 46 patients with incomplete data and 10 patients without follow-up (missing). The follow-up rate was 3.15%. Among 307 patients, 189 were male and 118 were female. The average length of stay was 8.04 (+ 4.36) days, and the total mortality rate was 37.67%. 2. Comparing with NYHA grade III and IV, the incidence of diabetes mellitus was higher in NYHA grade IV patients, and the heart rate was faster at admission. The duration of hospitalization was longer, and the difference was statistically significant between the two groups (P 0.05); NYHA grade IV patients, left atrial diameter and left atrial diameter index increased significantly, the degree of anemia worsened, hemoglobin level, hemoglobin concentration and content decreased, and the difference between the two groups was statistically significant (P 0.05). With the deterioration of heart function, chronic inflammation. The percentage and absolute value of leukocytes and neutrophils in patients with cardiac function grade IV were significantly higher than those in patients with cardiac function grade III (P 0.05). There was significant difference between the two groups (P 0.05). The serum sodium and calcium in the event group were significantly lower than those in the non-event group, and the difference between the two groups was statistically significant (P 0.05). The level of white blood cells and neutrophils in the event group was significantly higher than that in the non-event group (P 0.05). The e-GFR in the event group was significantly lower than that in the non-event group (P 0.05). The index of left atrial diameter and diameter was significantly higher than that of non-event group (P 0.05). There was a significant difference between the two groups (P 0.05). Multivariate analysis showed that diastolic pressure, frequent premature and short ventricular tachycardia, alkaline phosphatase, albumin, lymphocyte percentage, left ventricular posterior wall, and left atrial diameter index were independent risk factors for prognosis of all-cause death. The 1-year survival rate of patients with myopathy was significantly lower than that of patients with myopathy (P 0.05). Anemia, increased liver and kidney damage, increased left atrial volume, increased mortality. 2. All-cause mortality within one year was 37.67%. Diastolic blood pressure, left ventricular posterior wall, frequent premature and short ventricular tachycardia, alkaline phosphatase, lymphocyte percentage, serum albumin, and left atrial diameter index were independent risk factors for 1-year mortality in patients with ischemic cardiomyopathy. Risk factors. 3. Music score has a predictive value for the prognosis of patients with grade III and IV ischemic cardiomyopathy. Patients with score 20.5 have a significantly increased risk of all-cause mortality.
