Introduction: Heart failure represents a major challenge for healthcare systems worldwide. Rehabilitation is recommended as an important pillar of therapy for these patients, especially for those with reduced left ventricular ejection fraction (HFrEF: heart failure with reduced ejection fraction).
Methods: The data collected in this multi-center project provide information on the rates of patients with HFrEF who were treated in five German rehabilitation facilities and whether the patients adhered to drug therapy at 3-/6-month follow-up. The project was supported by an unrestricted grant from Novartis-Pharma-GmbH.
Results: The mean age of the 234 patients included was 63.4 ± 10.6 years and 78% were male. The mean LVEF was 31 ± 8% at admission and 36 ± 10% at discharge. Only 20.6% of the patients were assigned to rehabilitation with the main indication HF. The most frequent main indication was acute coronary syndrome (46.6%). A high proportion of patients was already on the recommended drug therapy upon admission (94% beta blockers, 100% angiotensin-effective drugs, 70% mineralocorticoid receptor antagonists, etc.). This was optimized, in particular by a higher proportion of patients treated with sodium-glucose cotransporter-2 inhibitors (35% admission vs. 45% discharge) and sacubitril/valsartan (49% admission vs. 64% discharge), which was further optimized during the 6-month follow-up (e.g., 50% SGLT2 inhibitors, 67% sacubitril/valsartan).
Discussion: These data illustrate the effect of rehabilitation in terms of optimizing drug therapy, which stabilized over the course of 6 months. Furthermore, only a few patients with the main diagnosis HFrEF are referred for cardiac rehabilitation, although it is an essential part of guideline-based therapy.
