Abstract 16990: Empagliflozin Therapy is Associated With Improved Left Ventricular Diastolic Function in Patients With Transthyretin Amyloid Cardiomyopathy
Abstract
Introduction:
Although SGLT-2 inhibitors demonstrated beneficial clinical effects in patients with heart failure with preserved ejection fraction, their role in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) remains undefined.
Hypothesis:
We investigated the effects of empagliflozin on myocardial function in patients with ATTR-CM.
Methods:
In a prospective single-center non-randomized cohort study we enrolled 15 consecutive patients with ATT-CM receiving tafamidis 61 mg qd and standard heart failure therapy for at least six months prior to enrolment. At the time of inclusion, all patients started receiving empagliflozin 10 mg qd. Biochemical and echocardiographic parameters were evaluated at baseline and again at 6-months.
Results:
At the time of inclusion, the average age of patients was 74.8±5.7 years, 14 (93%) were male, and 14 (93%) had NYHA class II symptoms; 10 (67%) patients were receiving ARNI/ACEI/ARB, 5 (33%) were treated with beta blockers, and 3 (20%) were receiving mineralocorticoid receptor antagonists. At 6-months follow-up we found no change in NT-proBNP levels (1694±1237 ng/L at baseline vs. 1549±1203 ng/L at follow up; P=0.78), hs-Troponin I levels (33±19 ng/L vs. 39±26 ng/L; P=0.50), or eGFR (65.9±14.4 mL/min vs. 64.9±14.8 mL/min; P=0.87). Furthermore, we observed no changes in LVEDV (84±19 mL vs. 88±17 mL; P=0.61), LVEF (57±8% vs. 57±7%; P=0.94), LV mass (265±74 g vs. 279±88 g; P=0.67), or RVIDd (39±8 mm vs. 36±7 mm; P=0.39). However, at 6…
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: 15 participants or records.
