RESUMEN
INTRODUCTION: Although several guidelines recommend that patients with heart failure with reduced ejection fraction (HFrEF) be treated with angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEI/ARB) or angiotensin receptor - neprilysin inhibitors (ARNI), beta-blockers, mineralocorticoid receptor antagonists (MRA), and sodium-glucose cocotransporter-2 inhibitor (SGLT2i), there are still several gaps in their prescription and dosage in Colombia. This study aims to describe the use patterns of HFrEF treatments in the Colombian Heart Failure Registry (RECOLFACA). METHODS: Patients with HFrEF enrolled in RECOLFACA during 2017-2019 were included. Heart Failure (HF) medications prescription and daily dose were assessed using absolute numbers and proportions. Therapeutic schemes of patients treated by internal medicine specialists were compared with those treated by cardiologists. RESULTS: Out of 2528 patients in the registry, 1384 (54.7%) had HFrEF. Among those individuals, 88.9% were prescribed beta-blockers, 72.3% with ACEI/ARBs, 67.9% with MRAs, and 13.1% with ARNIs. Moreover, less than a third of the total patients reached the target doses recommended by the European HF guidelines. No significant differences in the therapeutic schemes or target doses were observed between patients treated by internal medicine specialists or cardiologists. CONCLUSION: Prescription rates and target dose achievement is sub-optimal in Colombia. Nevertheless, RECOLFACA had one of the highest prescription rates of beta-blockers and MRAs compared to some of the most recent HF registries. However, ARNIs remain underprescribed. Continuous registry updates can improve the identification of patients suitable for ARNI and SGLT2i therapy to promote their use in clinical practice.
