Abstract: Background: Critical limb ischemia (CLI) represents the most advanced stage of peripheral arterial disease (PAD) and remains associated with substantial morbidity and mortality. Data from Sub-Saharan Africa are scarce despite a rapidly increasing burden of disease. Objective: To evaluate the epidemiological characteristics, therapeutic strategies, and outcomes of patients treated for CLI in a tertiary cardiovascular surgery center. Methods: A retrospective study was conducted from January 2020 to December 2023, including 65 patients managed for CLI. Epidemiological, clinical, imaging, therapeutic, and outcome variables were analyzed. Results: Mean age was 65.3 years; 54% were male. Hypertension (58%), smoking (38%), and diabetes (34%) were the most common risk factors. Trophic lesions were present in 80% of cases. Endovascular therapy was performed in 70.7% of patients, bypass surgery in 15.4%, and thrombo-endarterectomy in 13.8%. Perioperative complications occurred in 37%. Mortality reached 14%. A total of 56 amputations were performed (25 minor, 31 major). Diabetes was significantly associated with minor amputation, while diabetes, hypertension, and smoking predicted major amputation. Primary patency was 61.5% at 1 month and 52.3% at 1 year. Conclusion: CLI remains a severe condition with high rates of complications, amputation, and mortality. Endovascular therapy was the predominant strategy with acceptable early patency. Earlier diagnosis and improved cardiovascular risk management are essential to improve outcomes in Sub-Saharan Africa.

Abstract: 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.
