Introducción: Cardiovascular complications are among the leading causes of mortality in chronic renal failure patients. Detecting heart failure in early stages of asymptomatic patients has become a challenge and new strategies are needed to prevent and provide these patients with proper management. Since early recognition is crucial, echocardiography has become the cornerstone when used in chronic renal failure patients undergoing dialysis. The standard of care recommends early assessment in the first three months after dialysis started. Methods: A cross-sectional study was conducted at Carlos Andrade Marín Hospital with 61 patients having Renal Replacement Therapy. Brain Natriuretic Peptide (BNP) levels were compared to resting echocardiography for early identification of patients at risk of heart failure. Results: A 29% (95% CI: 0.15 to 0.43) prevalence of heart failure was observed in this group of patients. BNP sensitivity was 58% (95% CI: 0.32 to 0.81), specificity 62% (95% CI: 0.44 – 0.77), PPV 39% (95% CI: 0.16 – 0.61) and NPV 78% (95% CI: 0.61 to 0.95) to identify H.F. As much as 93% of our patients had cardiovascular problems identified by echocardiography. The most frequent abnormality was left ventricular diastolic dysfunction in 36% of cases. Discusion: There is a high prevalence of asymptomatic heart failure patients among dialytic users that should be recognized earlier. Regardless of the absolute BNP values, biomarkers are unsuitable to identify heart failure in renal patients. Echocardiography remains as a useful tool to assess here at function in renal patients.
