SGLT2 Inhibitors Are Associated with Left Ventricular Reverse Remodeling in Patients with Non-Compaction Cardiomyopathy—A Prospective Observational Cohort Trial
Abstract
Background/Objectives: Sodium glucose co-transporter 2 inhibitors (SGLT2is) improve outcomes in heart failure; however, data in left ventricular non-compaction cardiomyopathy (LVNC) patients are limited. We sought to analyze the clinical effects of the SGLT2is dapagliflozin and empagliflozin in patients with LVNC. Methods: Thirty consecutive LVNC patients diagnosed by CMR were prospectively enrolled. Clinical, biochemical and echocardiography data were obtained at the initiation of the SGLT2is and at the 12-month follow-up. All patients were on stable guideline-directed medical therapy. A response to SGLT2i therapy was defined as an improvement in LVEF ≥ 5% at 12 months. Results: Of the 30 enrolled patients, 25 were male, with a mean age of 49 ± 16 years and few comorbidities. Dapagliflozin 10 mg was prescribed to 23 patients and empagliflozin 10 mg to 7 patients. Five patients experiened an adverse event during follow-up (one sudden cardiac death; four heart transplantations or LVAD implantations). During follow-up, significant improvements were observed in LVEF (32.1 ± 6.9% vs. 43.5 ± 9.7%; p = 0.003), LVOT VTI (14.8 ± 6.5 cm vs. 17.6 ± 3.3 cm; p = 0.008), E/e′ (14.8 ± 4.7 vs. 10.0 ± 4.1; p < 0.001), and TAPSE (2.0 ± 0.4 cm vs. 2.3 ± 0.4 cm; p = 0.012). NT-proBNP levels decreased significantly (2025 ± 2198 pg/mL vs. 582 ± 803 pg/mL; p = 0.005). Eighteen patients responded favorably to SGLT2i therapy (Group A), whereas seven showed no significant LVEF improvement (Group B).…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 30 participants or records.
