Impact of age on clinical outcomes and response to serelaxin in patients with acute heart failure: An analysis from the RELAX‐AHF‐2 trial

Aims Acute heart failure (AHF) is a major cause of hospitalizations and death in the elderly. However, elderly patients are often underrepresented in randomized clinical trials. We analysed the impact of age on clinical outcomes and response to treatment in patients enrolled in Relaxin in Acute Heart Failure (RELAX‐AHF‐2), a study that included older patients than in previous AHF trials. Methods and results The RELAX‐AHF‐2 randomized patients admitted for AHF to infusion of serelaxin or placebo. We examined the association of pre‐specified clinical outcomes and treatment effect according to age categories [(years):
