Key result
Hospitalized LV failure and cardiomyopathy linked to ~7% in-hospital mortality, driven by arrhythmias and renal complications.
Why the study?
The global prevalence and incidence of heart failure are rising, with limited data on prevalence and outcomes of left ventricular failure and cardiomyopathy in tertiary hospitals in Bangladesh.
Observational (n=250)

Left ventricular failure and cardiomyopathy carry a significant burden in Bangladeshi tertiary hospitals, with a 7.2% in-hospital mortality rate and frequent complications like arrhythmias and renal impairment.
Background: The global prevalence and incidence of heart failure have been steadily rising, approaching epidemic levels, with a substantial impact on morbidity, mortality, and healthcare costs, and Bangladesh is experiencing a parallel rise in cardiovascular disease amid epidemiological transition. The purpose of the study is to determine the prevalence and clinical outcomes of left ventricular failure and cardiomyopathy in patients admitted to a tertiary care hospital. Objectives: The aim of the study was to determine the prevalence and clinical outcomes of left ventricular failure and cardiomyopathy in patients admitted to a tertiary care hospital. Methods & Materials: A retrospective study at the Department of Cardiology, Noakhali Medical College, Noakhali, Bangladesh (July 2024–June 2025) included 250 adults with left ventricular failure or cardiomyopathy, collecting demographics, clinical features, comorbidities, echocardiography, hospital stay, mortality, and complications; data were analyzed using SPSS v26 with descriptive statistics. Results: Among 250 patients (mean age 55.1 years; 70.4% male), left ventricular failure was most common (64.8%), dyspnoea was the predominant symptom (84%), and hypertension the leading comorbidity (52.8%). The mean LVEF was 38.9%, LV dilatation occurred in 52.8%, and the median hospital stay was 4 days. In-hospital mortality was 7.2%, with arrhythmias (10.4%), renal impairment (8.4%) and hyponatremia (15, 6.0%) being the major complications. Conclusion: Left ventricular failure and cardiomyopathy remain major causes of tertiary hospital admissions, presenting with typical heart failure features and comorbidities, and leading to measurable complications and mortality despite standard inpatient management.

Kabir et al. (2026) conducted an observational in Left ventricular failure and cardiomyopathy (n=250). Left ventricular failure or cardiomyopathy was evaluated on In-hospital mortality. Left ventricular failure and cardiomyopathy in hospitalized adults were associated with a 7.2% in-hospital mortality rate, with arrhythmias (10.4%) and renal impairment (8.4%) as major complications.
