| Sumario: | BACKGROUND Limited data are available on the long-term trajectory of estimated glomerular filtration rate (eGFR) in patients with chronic heart failure. OBJECTIVES The authors evaluated eGFR dynamics using the 2009 Chronic Kidney Disease Epidemiology Collaboration equation and its prognostic signi ficance in a real -world cohort over a 15 -year follow-up. METHODS A prospective observational registry of ambulatory heart failure outpatients was conducted, with regular eGFR assessments at baseline and on a 3 -month schedule for #15 years. Urgent kidney function assessments were excluded. Locally weighted error sum of squares curves were plotted for prede fined subgroups. Multivariable longitudinal Cox regression analyses were conducted to assess associations with all -cause and cardiovascular death. RESULTS A total of 2,672 patients were enrolled consecutively between August 2001 and December 2021. The average age was 66.8 +/- 12.6 years, and 69.8% were men. Among 40,970 creatinine measurements, 28,634 were used for eGFR analysis, averaging 10.7 +/- 8.5 per patient. Over the study period, a signi ficant decline in eGFR was observed in the entire cohort, with a slope of -1.70 mL/min/1.73 m 2 per year (95% CI: -1.75 to -1.66 mL/min/1.73 m 2 per year). Older patients, those with diabetes, a preserved ejection fraction, a higher baseline eGFR, elevated hospitalization rates, and those who died during follow-up experienced more pronounced decreases in the eGFR. Moreover, the decrease in kidney function correlated independently with all -cause mortality and cardiovascular death. CONCLUSIONS These findings highlight the sustained decline in eGFR over 15 years in patients with heart failure, with variations based on clinical characteristics, and emphasize the importance of regular eGFR monitoring in this population.
