Already low drug dose antagonism of the renin-angiotensin aldosterone system decreases 1-year mortality and rehospitalization in old heart failure patients - 10/09/22
Abstract |
Aims |
Hospitalization for heart failure treatment (HHF) is an incisive event in the course of HF. Today, the large majority of HHF patients is ≥ 65 years and discharge HF drugs are most often not applied at dose levels acknowledged to provide prognostic benefit. This study therefore aims to investigate the treatment effect size of discharge HF drugs in old HHF patients.
Methods |
Drugs are analyzed according to pharmacological class. Individual discharge HF drug dose is reported as percentage of guidelines-recommended target dose. Primary endpoint was 1-year all-cause mortality (ACM) after discharge; the secondary endpoint combined 1-year ACM and first cardiovascular hospitalization within 1 year after discharge. Comparison between 65–80 years and > 80 years old study participants tested the relative treatment effect size as a function of respective age group.
Results |
The 875 consecutive HHF patients had a median age of 82 years [76–87 years]; 48.6 % were females. Betablocker and diuretic treatment did not change the incidence of endpoints. Inhibition of the renin-angiotensin system (RASi), when compared to no treatment, decreased the incidence of endpoints both at the 1–25 % and the > 25 % target dose level. Antagonists of the mineralocorticoid receptor (MRA), when compared to no treatment, decreased the secondary endpoint at the 1–25 % target dose level but not at the > 25 % target dose level. The relative treatment effect size of RASi or MRA corresponded between the age strata for both endpoints.
Conclusion |
Low-dose RASi and MRA had beneficial effects in these old HHF patients.

Highlights |
• | Low dose renin-angiotensin system inhibition reduces 1-year mortality and the composite 1-year mortality or cardiovascular hospitalization . |
• | Very low target dose level of mineralocorticoid receptor antagonism decreases the composite endpoint in the >80 years old subgroup. |
• | Low percentage target dose of loop diuretics decreases 1-year mortality in the 65-80 years old subgroup. |
