Experiencia clínica con sacubitrilo/valsartán en pacientes con insuficiencia renal: la visión del nefrólogo

Abstract

Background and objectivesSacubitril/valsartan reduces cardiovascular morbidity and mortality in patients with systolic dysfunction. The aim of the present study was to assess the evolution of chronic kidney disease (CKD) patients after initiating sacubitril/valsartan. Material and methodsWe included 66 consecutive CKD patients with systolic dysfunction followed up in outpatient care. Patients had to meet the inclusion criteria of having a New York Heart Association class ii to iv, receiving maximum tolerated doses of optimal medical therapy and CKD stages 1 to 4. At baseline, comorbidities and epidemiological data were collected and low doses of sacubitril/valsartan were initiated. At month 1 and 3, doses of sacubitril/valsartan were increased up to the maximum doses if tolerated. In each visit, renal function and cardiac biomarkers were recorded. All the data were analyzed at the end of follow up (6 months). ResultsOf the 66 patients, 42 (63%) were men, with a mean age of 73±15 years. Mean creatinine at baseline was 1.42±0.5 mg/dL (glomerular filtration rate estimated by CKD-EPI was 50±19 mL/min/1.73 m2) and mean left ventricular ejection fraction (LVEF) was 31±9%. At the end of follow up, LVEF improved from 31±9% to 39±15% (P <0.001). After one month of treatment, renal function improved up to 53±21 mL/min/1.73 m2, P=0.005. For the remaining follow-up time, glomerular filtration rate remained stable (mean at end of follow-up 51±18 mL/min/1.73 m2). Seven patients (10.6%) withdrew from treatment. ConclusionIn our experience, sacubitril/valsartan is safe in CKD, offering stability in CKD progression after 6 months.
