Factors affecting hospitalization and mortality in a retrospective study of elderly patients with heart failure

Björklund, Johan ; Pettersson, Louise LU orcid and Agvall, Björn LU orcid (2024) In BMC Cardiovascular Disorders 24(1).
Abstract

Background: Heart failure (HF) has a high prevalence in an elderly population and leads to a substantial hospitalization and mortality. The objective of this study was to investigate factors that affect hospitalization and mortality in an elderly population. Methods: A retrospective observational study was conducted of HF patients aged 76–95 years residing in Region Halland, Sweden. Between 2013 and 2019, a total of 3134 patients received a novel diagnosis of HF and were subsequently monitored for one year using data from a healthcare database. The patients were categorized into HF-phenotypes according to ejection fraction (EF) and those with HF diagnose solely based on clinical criteria with no defined EF. Cox regression analysis for...

Background: Heart failure (HF) has a high prevalence in an elderly population and leads to a substantial hospitalization and mortality. The objective of this study was to investigate factors that affect hospitalization and mortality in an elderly population. Methods: A retrospective observational study was conducted of HF patients aged 76–95 years residing in Region Halland, Sweden. Between 2013 and 2019, a total of 3134 patients received a novel diagnosis of HF and were subsequently monitored for one year using data from a healthcare database. The patients were categorized into HF-phenotypes according to ejection fraction (EF) and those with HF diagnose solely based on clinical criteria with no defined EF. Cox regression analysis for hospital admissions and mortality was evaluated adjusted for pharmacotherapies, healthcare utilization and clinical characteristics. Results: Echocardiogram was performed in 56% of the patients and 51% were treated with recommended HF pharmacotherapy with betablockers combined with renin-angiotensin-aldosterone-system inhibition. The average number of inpatient days was 10.7 while the average number of visits to primary care physician was 5.4 and 8.7 to primary care nurse respectively. A Cox regression analysis for hospital admissions and mortality revealed that an eGFR < 30 ml/min was associated with a hazard ratio (HR) of 1.88 (confidence interval [CI] 1.56–2.28), elevated NT-proBNP with an HR of 2.09 (CI 1.59–2.76), diabetes with an HR of 1.31 (CI 1.13–1.52), and chronic obstructive pulmonary disease with an HR of 1.51 (CI 1.29–1.77). Having a primary care physician visit was associated to an HR of 0.16 (CI 0.14–0.19), and the use of recommended heart failure pharmacotherapy was associated with an HR of 0.52 (CI 0.44–0.61). Conclusions: In a Swedish elderly population with HF, factors such as advancing age, kidney dysfunction, elevated NT-proBNP levels, diabetes, and COPD were associated with an increased risk of both mortality and hospitalization. Conversely, patients who received recommended heart failure treatment and made regular visits to their primary care physician were associated with a decreased risk. This indicates that elderly patients with HF benefit from recommended HF treatment and highlights that follow-ups in primary care could be advantageous.
