Hospital mortality in patients with heart failure in Germany – cross-sectional study
Prof. Dr. re. medical habil. Karel Kostev MA / Dipl.-Inf. Oliver Laduch / Prof. Dr. med. Mark Lüdde MHBA
The aim of this study was to investigate the prevalence and factors associated with in-hospital mortality in patients with heart failure (HF). This multicenter cross-sectional study was based on data from HF patients from fourteen hospitals across Germany. A total of 19,288 inpatients (15,431 patients) were included (mean age: 79.4 years, 49.9% female). Mortality was 9.7%, increasing from 4.2% in the age group ≤65 years to 15.1% in the age group >90 years. Left heart failure with symptoms at rest, acute renal failure, respiratory failure, pneumonia, and pleural effusion were associated with an increased risk of death. Paradoxically, several chronic cardiovascular and metabolic diseases—including hypertensive heart disease, essential hypertension, pulmonary heart disease, obesity, dyslipidemia, and diabetes—were associated with a lower risk of death as secondary diagnoses. While our study provides a comprehensive snapshot of in-hospital mortality in HF patients, it also highlights the need for further studies to better understand the complex interplay of various risk factors.

Abstract: Krankenhaussterblichkeit bei Patienten mit Herzinsuffizienz in Deutschland – Querschnittsstudie
Ziel dieser Studie war es, die Prävalenz und die Faktoren zu untersuchen, die mit der Krankenhaussterblichkeit von Patienten mit Herzinsuffizienz (HI) assoziiert sind. Die multizentrische Querschnittsstudie basierte auf Daten von HI-Patienten aus vierzehn Krankenhäusern in ganz Deutschland. Insgesamt wurden 19.288 stationäre Fälle (15.431 Patienten) eingeschlossen (Durchschnittsalter: 79,4 Jahre, 49,9% weiblich). Die Sterblichkeit betrug 9,7% und stieg von 4,2% in der Altersgruppe ≤65 Jahre auf 15,1% in der Altersgruppe >90 Jahre an. Linksherzinsuffizienz mit Symptomen in Ruhe, akute Niereninsuffizienz, respiratorische Insuffizienz, Lungenentzündung und Pleuraerguss waren mit einem erhöhten Sterberisiko assoziiert. Paradoxerweise waren mehrere chronische kardiovaskuläre und metabolische Erkrankungen – darunter hypertensive Herzkrankheit, essenzielle Hypertonie, pulmonale Herzkrankheit, Adipositas, Fettstoffwechselstörungen und Diabetes – als Nebendiagnosen mit einem geringeren Sterberisiko assoziiert. Unsere Studie liefert zwar eine umfassende Momentaufnahme der Krankenhaussterblichkeit von HI-Patienten, macht aber auch deutlich, dass weitere Studien notwendig sind, um das komplexe Zusammenspiel verschiedener Risikofaktoren besser zu verstehen.
Abstract: In-hospital mortality in patients hospitalized with heart failure in Germany – cross-sectional study
The goal of this study was to investigate the prevalence of and the factors associated with the in-hospital mortality of patients hospitalized with heart failure (HF). This multicenter cross-sectional study was based on data of HF patients cases from fourteen hospitals across Germany. A total of 19,288 hospitalized cases (15,431 patients) were included (mean age: 79.4 years, 49.9% female). The mortality rate was 9.7% and increased from 4.2% in the age group ≤65 years to 15.1% in the age group >90 years. Left ventricular failure with symptoms at rest, acute renal failure, respiratory failure, pneumonia, and pleural effusion were associated with a higher mortality risk. Paradoxically, several chronic cardiovascular and metabolic diseases as secondary diagnoses including hypertensive heart disease, essential hypertension, pulmonary heart disease, obesity, lipid metabolism disorders, and diabetes were associated with lower mortality risk. While our study provides a comprehensive snapshot of in-hospital mortality in HF patients, it also highlights the need for ongoing research to deepen our understanding of the intricate interplay between various risk factors.
