Renal dysfunction was present in 58.0% of patients with chronic heart failure and was significantly associated with older age, hypertension, diabetes mellitus, and advanced NYHA functional class.

More than half of patients with chronic heart failure in this cohort had renal dysfunction, highlighting the high burden of cardiorenal syndrome and the need for routine renal assessment.
Chronic heart failure is a major global health problem associated with substantial morbidity and mortality, and its close interaction with renal function through the cardiorenal syndrome significantly influences disease progression and outcomes. Renal dysfunction is commonly encountered in patients with chronic heart failure and is known to be associated with adverse prognosis; however, its burden in routine clinical settings, particularly in local populations, remains insufficiently characterized. The purpose of this study was to determine the prevalence of renal dysfunction among patients with chronic heart failure and to examine its association with key clinical variables. To achieve this, a hospital-based cross-sectional study was conducted in the Department of Cardiology at Satkhira Medical College and Hospital, Bangladesh, including 150 patients diagnosed with chronic heart failure. Relevant demographic and clinical data were collected, and renal function was assessed using estimated glomerular filtration rate calculated by the CKD-EPI equation. Statistical analysis was performed to evaluate the relationship between renal dysfunction and selected variables. The findings demonstrated that renal dysfunction was present in 58.0% of patients, with moderate impairment being the most common pattern, and was significantly associated with older age, hypertension, diabetes mellitus, and advanced NYHA functional class. In conclusion, this study highlights the substantial burden of renal dysfunction among patients with chronic heart failure and emphasizes the importance of routine renal function assessment for early identification and improved clinical management in this high-risk population.
