Treatment with renin‐angiotensin system inhibitors and prognosis of heart failure with preserved ejection fraction: A propensity‐matched study in the community

Aims There is currently no consensus on the effect of treatment with angiotensin‐converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), on the prognosis of patients with heart failure and preserved ejection fraction (HFpEF). Therefore, we have analysed the relationship of commencing treatment with ACEIs or ARBs and the prognosis of patients with incident HFpEF. Methods Retrospective study over 15 years on 3864 patients with HFpEF (GAMIC cohort). Main outcomes were mortality (all‐cause and cardiovascular) and hospitalisations for HF. The independent relationship between CT‐RASIs and the prognosis, stratifying patients for cardiovascular comorbidity after propensity score‐matching was analysed. Results During a median follow‐up of 7.94 years, 2960 died (76.6%) and 3138 were hospitalised (81.2%). Therapy with RASIs was associated with a lower mortality, all‐cause (RR [95% CI] for ACEIs: 0.76 [0.66‐0.86], and RR for ARBs: 0.88 [0.80‐0.96]; P
