Prevalence of diastolic heart failure in patients with type 2 Diabetes mellitus in a tertiary care hospital: A study from Kolkata.

Introduction: Heart failure is one of the most common reasons for hospital admission in those aged 65 and over with consequent high costs for the healthcare system. Despite improvements in the treatment of patients with chronic HF with reduced EF, the survival of the patients hospitalized for HF remains poor, with one-year mortality of 30% and 5-year mortality up to 50%. Objective: To determine the prevalence of diastolic heart failure in patients with type 2 Diabetes mellitus in a tertiary care hospital. Methodology: This study was hospital based Cross-sectional observational study conducted in In-patient and outpatient department of Apollo Gleneagles Hospitals Kolkata involving 85 patients between 40-65 years of age both males and females from the general medical inpatient and outpatient pool of Apollo Gleneagles Hospitals Kolkata. Results: Prevalence of diastolic dysfunction was 63.5% among the patients with type-2 DM. Only 14.8% and 7.4% of the patients had Grade-III and Grade-IV DD respectively. Chi-square test showed that there was significant association between age and Diastolic Dysfunction of the patients (p<0.0001). Chi-square test showed that there was significant association between gender and DD of the patients (p=0.019). Chi-square test showed that there was significant association between obesity and DD of the patients (p=0.002). Conclusion: There was significant association between age and diastolic dysfunction of patients (p<0.0001). Obesity is a strong risk factor for heart failure. Chi-square test showed that there was significant association between obesity and DD of patients (p=0.002). There was significant association between level of HbA1c and DD of the patients. Prevalence of DD increases with value of HbA1c. [ABSTRACT FROM AUTHOR]
