RESUMO
(1) Background: The validation of new lines of therapy for the elderly is required due to the progressive ageing of the world population and scarce evidence in elderly patients with HF with reduced ejection fraction (HFrEF). The purpose of our study is to analyze the effect of SGLT2 inhibitors (SGLT2i) in this subgroup of patients. (2) Methods: A single-center, real-world observational study was performed. We consecutively enrolled all patients aged ≥ 75 years diagnosed with HFrEF and for treatment with SGLT2i, and considered the theoretical indications. (3) Results: A total of 364 patients were recruited, with a mean age of 84.1 years. At inclusion, the mean LVEF was 29.8%. Median follow-up was 33 months, and there were 122 deaths. A total of 55 patients were under SGLT2i treatment. A multivariate Cox logistic regression test for all-cause mortality was performed, and only SGLT2i (HR 0.39 [0.19-0.82]) and glomerular filtration rate (HR 0.98 [0.98-0.99]) proved to be protective factors. In parallel, we conducted a propensity-score-matched analysis, where a significant reduction in all-cause mortality was associated with the use of SGLT2i treatment (HR 0.39, [0.16-0.97]). (4) Conclusions: Treatment with SGLT2i in elderly patients with HFrEF was associated with a lower rate of all-cause mortality. Our data show that SGLT2i therapy could improve prognosis in the elderly with HFrEF in a real-world study.
RESUMO
BACKGROUND: Beta-blockers (BBs) remain underused in elderly patients with reduced ejection fraction (REF). Our aim was to determine the prognostic impact of different doses of BB in this setting. METHODS AND RESULTS: A single-center observational study was conducted. Inclusion criteria were age≥75 and EF≤0.35. Six months after diagnosis, patients were divided into 3 groups depending on BB dose: no BB (NBB), low dose (<50% of the target dose) (LD), and high dose (≥50%) (HD). Two different analytical approaches were employed: multivariate Cox model and propensity-score (PS) matching. Outcomes were all-cause death and heart failure (HF) admission. We included 559 patients (134 NBB, 259 LD, and 166 HD) with median follow-up of 29.9months. There were 212 deaths (NBB: 70 (52.2%); LD: 94 (36.3%); and HD: 48 (28.9%)) and 171 HF admissions (NBB: 42 (31.3%); LD: 85 (32.8%); and HD: 44 (26.5%)). On multivariate analysis, both LD and HD were associated with improved survival, with no differences between them (HD vs. NBB=0.67, 95% CI=[0.46-0.98], p=0.037; HD vs. LD=1.03, 95% CI=[0.72-1.46], p=0.894; and LD vs. NBB=0.65, 95% CI=[0.48-0.90], p=0.009). However, BB therapy failed to show benefits in HF admissions (p=NS, for each comparison). PS-matched analysis included 198 patients, with similar results to those mentioned above. CONCLUSIONS: BB therapy was associated with a significant reduction in mortality among elderly patients with REF, regardless of dose. Nevertheless, it was not associated with a decrease in HF admissions. Further studies are needed to determine the optimal BB dose in these patients.

A previously non-described cause of mitral regurgitation is presented. An asymptomatic 50-year old male who was casually diagnosed of mitral valve Barlow's disease underwent cardiac surgery due to severe mitral regurgitation. In the operating theatre, a longitudinal fissure of 1.5-2.0 cm length, along the posterior mitral leaflet, was found responsible for the insufficiency. This defect had features of a potential congenital origin and it was successfully repaired with direct suture. Whether it is an atypical mitral cleft, a variation of Barlow's morphology spectrum or a new congenital heart defect remains unclear.
