| Objective:The purpose of this study was to investigate the prognosis of patients with heart failure after myocardial infarction in different BMI groups,so as to explore the effects of different BMI on survival rate,incidence of cardiovascular events,and readmission rate of cardiovascular events in patients with heart failure after myocardial infarction,and to discuss weight control recommendations for patients with heart failure after myocardial infarction in clinical practice.Methods:We collected patients between 2014.01 to 2014.12 in the first affiliated hospital of shanxi medical university first option for heart failure after myocardial infarction,cardiac function grade III-IV,underwent coronary angiography and heart colour to exceed check,clear diagnosis of myocardial infarction,rule out congenital heart disease,rheumatic heart disease,valvular disease,enlarge,poorly controlled hypertension for years,persistent atrial fibrillation,hyperthyroidism may increase a risk factor for the development of heart failure with non cardiovascular prognosis of patients with chronic diseases but the impact of such as COPD,chronic renal failure,tumor disease patients,a total of 123 cases followed up to December 2018,Patients' age,gender,previous disease,smoking history,number of re-hospitalization within 5 years,occurrence of major cardiovascular events(acute exacerbation of heart failure re-hospitalization,new myocardial infarction,malignant arrhythmia,all-cause death,etc.)and the time from diagnosis to cardiovascular events were collected.SPSS24.0 software was used to conduct correlation statistical processing for all data in the hospital,and normality test was performed.Natural logarithm transformation was performed for non-normal distribution data.The baseline measurement data was described by mean(standard deviation)if it was in line with the normal distribution,the data between groups were compared by t test,and the data between groups with non-normal distribution was compared by Spearman mass correlation.Classification variables were expressed by the number of cases(%).The data between the two groups were compared by test,and the prognostic analysis was performed by COX regression analysis.The difference in the prognosis of patients with ischemic heart failure at different BMI levels was analyzed by P < 0.05.Results:The results of this study showed that 123 patients were followed up for an average of 57 months,among which 91 patients had major cardiovascular events and 32 patients had no major cardiovascular events.16(13%)in the low-weight group,64(52%)in the normal-weight group,36(29.3%)in the super-recombinant group,and 7(5.7%)in the obese group.The number of re-hospitalization within 5 years in the low-weight group was 2(2),the number of re-hospitalization within 5 years in the normal-weight group was 1(2),the number of re-hospitalization within 5 years in the super-recombinant group was 2(2),and the number of re-hospitalization within 5 years in the obesity group was 3(2).For each increase in BMI,the prognostic risk of the patients was reduced by about 12%.In addition,the results showed that age and diabetes were also associated with the prognosis of patients with heart failure after myocardial infarction,and the difference was statistically significant(P<0.05).The risk increased by about 6% for every 1 year of age,and the risk increased by about 40% for patients with diabetes compared with those without diabetes.At the same time,the results showed that the increase of BMI was not significantly correlated with the time of cardiovascular events(P=0.462).Conclusion:The increase of BMI had a protective effect on the prognosis of patients with heart failure after myocardial infarction,but the number of readmissions and the time of major cardiovascular events were not significantly improved with the increase of BMI. |
