Abstract
BACKGROUND: Diabetes mellitus causes ischemic heart disease (IHD) through macrovascular or microvascular involvement. Diabetes-associated hypertension, dyslipidemia, and obesity further increase coronary artery disease risk and can cause left ventricular hypertrophy leading to heart failure with preserved ejection fraction independent of IHD. This study was undertaken to evaluate the differences in demographics, clinical characteristics, Echocardiographic parameters, management, and outcomes between non-ischemic cardiomyopathy (NICM) and ischemic cardiomyopathy (ICM) patients in cohort of diabetes patients. METHODS: This retrospective study included diabetes patients with reduced ejection fraction (≤40) who were hospitalized with heart failure between January 2014 and February 2020. Patients were divided into two groups: group 1; ICM and group 2; NICM. Data obtained on above mentioned features including mortality and heart failure readmissions were compared between the two groups. RESULTS: A total of 612 diabetes patients admitted with acute heart failure were screened of which 442 were included. Group 1 (ICM) had 361 patients (81.7%) and group 2 (NICM) had 81 patients (18.3%). Patients in group 1 were older, predominantly males and with higher prevalence of hypertension, smoking and insulin dependent Diabetes while group 2 patients had higher BMI and higher prevalence of cardiac rhythm problems. No significant difference was detected in 5-year-mortality between the two groups (P=0.165). However, heart failure associated hospitalizations were higher in group 2 though it was not statistically significant (P=0.062). CONCLUSION: There was no difference in 5-years mortality between ICM and NICM in diabetes patients. However, NICM patients had higher prevalence of obesity and rhythm problems. AJCD
