Abstract
Background: The sodium-glucose co-transporter 2 inhibitors (SGLT2i) have improved the outcomes of patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). However, their effects in cardiac resynchronization therapy (CRT) recipients are relatively scarce. This study has investigated the impact of SGLT2i treatment on clinical and echocardiographic outcomes in CRT patients at long-term follow-up.
Methods: Patients with HF, New York Heart Association (NYHA) II-III class, and LVEF ≤ 35% referred for CRT implant were enrolled. Patients were grouped in non-SGLT2i (1st group) and SGLT2i treatment (2nd group) cohorts. Clinical and echocardiographic outcomes were evaluated at 24 months. Patients were classified as CRT responders if they remained alive without HF hospitalization, experienced an improvement of at least one NYHA class, and had left ventricular end-systolic volume reduction ≥ 15%.
Results: A total of 82 patients were enrolled. At 24-month follow-up, 22 of 41 (53.6%) patients in the 1st group and 32 of 41 (78.0%) in the 2nd group were classified as CRT responders (p = 0.019). In multivariable analysis, the left bundle branch block eligible to Strauss criteria (LBBBS) (odds ratio (OR) 9.58; confidence interval (CI) 95% 1.71-53.53; p = 0.01) and SGLT2i treatment (OR 3.32; CI 95% 1.18-9.30; p = 0.022) were independent predictors of CRT response.
Conclusion: The SGLT2i treatment in CRT patients improves the combined CRT response at long-term follow-up. In our patient cohort, the CRT response is associated with LBBBS morphology and SGLT2i treatment.
期刊介绍：
The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
