摘要
Background The Kidney Disease Improving Global Outcomes (KDIGO) classification integrates both estimated glomerular filtration rate(eGFR) and urine-albumin-creatinine-ratio to stratify risk more comprehensively in patients with chronic kidney disease. There are limited data assessing whether this classification system is associated with prognosis and treatment response in heart failure populations. Methods PARADIGM-HF was a global RCT evaluating sacubitril/valsartan vs. enalapril in patients with HFrEF. Patients were classified according to low, moderate, and high/very high KDIGO risk. Treatment responses were assessed according to baseline KDIGO risk. The primary outcome was a composite of CV death or HF hospitalization. A renal composite outcome was defined as sustained decline in eGFR by ≥40% or end stage kidney disease. Results Among 1,910 (23% of total) participants with available data, 42%, 32%, and 26% were classified as low, moderate, and high/very high KDIGO risk, respectively. Patients in the highest KDIGO risk categories experienced the highest rates of the primary composite outcome (7.6[6.5-9.0], 9.4[7.9-11.2], 14.9[12.7-17.6] per 100py; P<0.001). Sacubitril/valsartan had a similar safety profile and similarly reduced the risk of both the primary outcome (PInteraction=0.31) and the renal composite outcome (PInteraction=0.50) across the spectrum of KDIGO risk. Conclusion One in 4 patients with HFrEF were classified as at least high KDIGO kidney risk; these individuals faced concordantly the highest risks of CV events. Sacubitril/valsartan exhibited consistent CV and kidney protective benefits as well as safety across the spectrum of baseline kidney risk. These data further support initiation of sacubitril/valsartan in HFrEF across a broad range of kidney risk.
