Latest pharmaceutical approaches across the spectrum of heart failure.

Despite major advances in prevention and medical therapy, heart failure (HF) remains associated with high morbidity and mortality, especially in older and frailer patients. Therefore, a complete, guideline-based treatment is essential, even in HF patients with conditions traditionally associated with a problematic initiation and escalation of the medical HF therapy, such as chronic kidney disease and arterial hypotension, as the potential adverse effects are overcome by the overall decrease of the absolute risk. Furthermore, since the latest data suggest that the benefit of a combined medical therapy (MRA, ARNI, SGLT2i, beta-blocker) may extend up to a LVEF of 65%, further trials on these subgroups of patients (HFmrEF, HFpEF) are needed to re-evaluate the guideline-directed medical therapy across the HF spectrum. In particular, the use of SGLT2i was recently extended to HFpEF patients, as evidenced by the DELIVER and EMPEROR-preserved trials. Moreover, the indication for other conservative treatments in HF patients, such as the intravenous iron supplementation, was accordingly strengthened in the latest guidelines. Finally, the possible implementation of newer substances, such as finerenone, in guideline-directed medical practice for HF is anticipated with great interest.

Safety and Efficacy of Traditional Heart Failure Therapies in Patients With Cardiac Amyloidosis and Heart Failure.

Randomized controlled trials have demonstrated mortality benefits for several medication classes in patients with heart failure (HF), especially with reduced ejection fraction (EF). However, the benefit of these traditional HF therapies in patients with HF from cardiac amyloidosis is unclear. our study aimed to evaluate the safety and efficacy of traditional HF therapies in patients with cardiac amyloidosis and HF with reduced EF or HF with mid-range EF (HFmrEF). We conducted a single-center retrospective study. Patients were included if they were diagnosed with cardiac amyloidosis and HF with reduced EF or HF with mid-range EF between January 2012 and 2022. The primary outcomes of interest were medication use patterns (for ß blockers [BB], angiotensin-converting enzyme inhibitors [ACEI], angiotensin receptor blockers [ARBs], angiotensin receptor neprilysin inhibitors [ARNI], and mineralocorticoid receptor antagonists [MRAs]); potential medication side effects (symptomatic bradycardia, fatigue, hypotension, lightheadedness, and syncope); hospitalization; and death. The associations of BB, ACEI/ARB/ARNI, and MRA use with clinical outcomes were evaluated using Kaplan-Meier and Cox proportional hazards regression. A total of 82 patients met study criteria. At time of cardiac amyloidosis diagnosis, 63.4% were on a BB, 51.2% were on an ACEI/ARB/ARNI, and 43.9% were on an MRA. At last follow-up, 51.2% were on a BB, 35.4% were on an ACEI/ARB/ARNI, and 43.9% were on an MRA. There were no statistically significant differences in rates of potential medication side effects in patients on the medication class compared with those who were not. There was no association with hospitalization or mortality for baseline or follow-up BB, ACEI/ARB/ARNI, or MRA use. In conclusion, BBs, ACEI/ARB/ARNIs, and MRAs may be safely used in this population. However, their use does not appear to improve mortality or hospitalization.
