Clinical profile, treatment patterns and one-year outcome of heart failure patients admitted in tertiary care hospital of North India.

Introduction: Because of wide heterogeneity in the epidemiology of heart failure among different populations, it is imperative to establish population-specific databases.

Aims And Objectives: To describe the clinical profile, treatment patterns, and outcomes of heart failure patients admitted to our tertiary care hospital.

Material And Methods: The study was a prospective observational study conducted over two years at our tertiary care hospital. It included patients admitted with acute and acute-on-chronic heart failure.

Results: We recruited 264 patients. Mean age of the study population was 57.8 ± 15.14 years. Males were 157 (59.5%). Dilated cardiomyopathy was the most common cause followed by ischemic heart disease. Most common risk factors were hypertension, tobacco use, anemia, and diabetes. Heart failure with reduced ejection fraction was present in 154 (62%) patients. Acute de novo heart failure was present in 91 (34.5%) patients. The most common precipitant for heart failure exacerbation was infection, followed by ischemic causes and non-adherence to drugs. The mean duration of hospital stay was 7.5 ± 3.1 days. The in-hospital mortality was 8.7%, and cumulative six-month and one-year mortality was 23% and 28%, respectively. In multivariate analysis, renal failure, readmission, and not being on guideline-directed medical treatment were significant predictors of mortality.

Conclusion: Our patients were younger, predominantly males, with dilated and ischemic cardiomyopathy as commonest etiology. Hypertension and tobacco smoking were most common risk factors, with infections as most common precipitants. Only one-third of patients were on guideline-directed medical therapy. The one-year mortality was 28% and was higher in those without guideline-directed medical therapy.
