Neurohormonal Therapy in Patients With Transthyretin Cardiac Amyloidosis: Is it an Option?
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNeurohormonal therapy is strongly recommended for heart failure with reduced left ventricular ejection fraction (LVEF). However, its role in transthyretin cardiac amyloidosis remains uncertain given concerns regarding tolerability and the perception that systolic dysfunction reflects an irreversible situation. CASES SUMMARY: We report 3 patients with wild-type transthyretin cardiac amyloidosis (wtATTR-CA) who initially presented with heart failure and reduced LVEF (≤35%). Guideline-directed medical therapy was initiated and was carefully titrated. During follow-up, these patients experienced clinical improvement and recovery of LVEF to ≥50%, allowing subsequent initiation of tafamidis, which is only approved for LVEF ≥50% in our country. DISCUSSION: These cases suggest that neurohormonal therapy may be feasible and beneficial in selected patients with wtATTR-CA and reduced LVEF, challenging the traditional paradigm of irreversible systolic dysfunction. TAKE-HOME MESSAGES: Guideline-directed medical therapy may be considered on an individualized basis in patients with wtATTR-CA and reduced LVEF. Some patients may tolerate treatment and experience improvement.
