Heart failure treatment in the last years of life: A nationwide study of 364 000 individuals.

AIMS: In patients with heart failure, treatment patterns in the last years of life have not been assessed at large scale. We aimed to assess whether heart failure treatment patterns up to 5 years prior to death changed over time.

METHODS AND

RESULTS

In a cohort study covering the whole Swedish population, we assessed all heart failure patients who died between 1 July 2007 and 31 December 2020 for evidence-based treatments. The proportion on the respective treatment at the time of death was examined by year of death using binomial regression. Looking back in time, treatment discontinuation rates were estimated using Poisson regression on time-split data. Combining these models, the proportion on each medication was estimated up to 5 years prior to death. A total of 364 480 patients died with heart failure during the study period. Half were women, and the median (interquartile range) age at death was 86 (79-90). The use of all heart failure treatments decreased gradually closer to death, but the discontinuation rate of beta blockers decreased over time, resulting in an increasing proportion of patients on treatment at the time of death.

CONCLUSION

In patients with heart failure, a changing pattern of medical treatment during the last years of life was observed, most notably with an increasing use of beta blockers. This may in part be due to a changing pattern of comorbidities over time, with an increase in e.g. hypertension and atrial fibrillation, but a decline in ischaemic heart disease.
