BACKGROUND: Angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEis/ARBs) and mineralocorticoid receptor antagonists (MRAs) have been shown to benefit patients with heart failure with reduced ejection fraction (HFrEF). However, there is a lack of information on the advantages of these drugs for patients with chronic kidney disease (CKD), and this gap is especially pronounced in elderly patients.
OBJECTIVE: The objective of this study was to assess the role of treatment consisting of ACEi/ARBs and MRAs in patients ≥ 75 years of age with CKD.
METHODS: From January 2008 to July 2014, 390 consecutive patients ≥ 75 years of age with an ejection fraction ≤ 35% and a glomerular filtration rate (GFR) ≤ 60 mL/min/1.73 m2 were included. We analyzed the relationship between treatment with ACEi/ARBs and MRAs and mortality or cardiovascular events.
RESULTS: Three hundred and ninety patients were included, with a mean age of 82.6 ± 4.1 years. Mean ejection fraction was 27.9 ± 6.5%. Renal dysfunction was mild (GFR 45-60 mL/min/1.73 m2) in 50.3% of patients, moderate (GFR 30-44 mL/min/1.73 m2) in 37.4%, and severe (GFR < 30 mL/min/1.73 m2) in 12.3%. After 32 ± 23 months, 68.7% of patients were receiving ACEi/ARBs and 40% were receiving MRAs; 65.9% developed a cardiovascular event and 54.4% had died. After multivariate Cox regression analysis, ACEi/ARB treatment was independently associated with a decreased rate of cardiovascular events (hazard ratio 0.71 [95% confidence interval 0.50-0.98]) and MRAs were not associated with a decrease in cardiovascular events or total mortality.
CONCLUSIONS: Treatment with ACEi/ARBs in elderly patients with HFrEF and CKD was associated with a lower rate of cardiovascular events, though MRA treatment failed to reduce the risk of morbidity and mortality in our population.
