ABSTRACT
BACKGROUND:
Transthyretin cardiomyopathy (ATTR-CM) was an exclusion criterion in randomized clinical trials of sodium-glucose cotransporter 2 inhibitors (SGLT2i).OBJECTIVES:
This study sought to assess the effectiveness and tolerability of SGLT2i in patients with ATTR-CM.METHODS:
Data of 2,356 consecutive ATTR-CM patients (2014-2022) were analyzed 260 (11%) received SGLT2i. After comparing the groups according to the treatment, 14 variables were significantly different-age and N-terminal pro-B-type natriuretic peptide were included in the model. A propensity score reflecting the likelihood of being treated with SGLT2i for each patient was determined using 16 variables.RESULTS:
The study comprised 220 patients treated with SGLT2i (age 77 ± 2 years; 82.3% wild-type ATTR-CM; left ventricular ejection fraction 45.8% ± 11%) and 220 propensity-matched control individuals. Adequacy of matching was verified (standardized differences <0.10 between groups). Discontinuation rate for SGLT2i was 4.5%; at 12 months, SGLT2i treatment was associated with less worsening of NYHA functional class, N-terminal pro-B-type natriuretic peptide, estimated glomerular filtration rate, and fewer new initiations of loop diuretic agent therapy. Over 28 months (Q1-Q3 18-45 months), SGLT2i therapy was associated with lower all-cause mortality (HR 0.57; 95% CI 0.37-0.89; P = 0.010), cardiovascular mortality (HR 0.41; 95% CI 0.24-0.71; P < 0.001), heart failure (HF) hospitalization (HR 0.57; 95% CI 0.36-0.91; P = 0.014), and the composite outcome of cardiovascular mortality and HF hospitalization (HR 0.57; 95% CI 0.38-0.84; P = 0.003).CONCLUSIONS:
SGLT2i treatment in ATTR-CM patients was well tolerated and associated with favorable effects on HF symptoms, renal function, and diuretic agent requirement over time. SGLT2i treatment was associated with reduced risk of HF hospitalization and cardiovascular and all-cause mortality, regardless of the ejection fraction, despite the effect size being likely overestimated. In the absence of randomized trials, these data may inform clinicians regarding the use of SGLT2i in patients with ATTR-CM.Mots clés
