Effect of anti-fibrotic therapy on regression of myocardial fibrosis after TAVI: design and rationale of the Reduce-MFA DZHK25 trial.
Trial report in ESC heart failure, 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
aimsMyocardial fibrosis (MF) represents a key player in transition to heart failure in aortic stenosis (AS), and AS patients with high baseline MF are at increased risk to die within 12 months after transcatheter aortic valve implantation (TAVI). Therefore, the objective of the Reduce-MFA DZHK25 trial is to assess the impact of anti-fibrotic therapy on regression of AS-induced MF after TAVI in patients with high baseline fibrotic burden. Key secondary objectives include reverse LV remodelling, symptomatic improvement, and reduction of mortality and cardiac hospitalizations.
methodsReduce-MFA represents a national, prospective, randomized, parallel group, controlled, open-label interventional multi-centre trial with blinded outcome assessment (PROBE design) enrolling patients with severe AS scheduled for TAVI. The anti-fibrotic principles employed are spironolactone and low-dose dihydralazine (epigenetic reactivation of anti-fibrotic genes). Baseline burden and course of MF are assessed by cardiac MRI (CMR). Since CMR-derived extracellular volume fraction (ECV%) ≥ 25.9% emerged as independent mortality predictor, only patients above this cut-off are randomized into three parallel groups: (i) Standard of Care alone, (ii) + spironolactone, (iii) + spironolactone + low-dose dihydralazine, each for 12 months. To assess MF regression, CMR is repeated after 12 months. MF is assessed by quantification of the ECV-derived LV matrix volume using T1 mapping. Additionally, measures of heart failure (Kansas City Cardiomyopathies Quality of Life Questionnaire, 6MWT, NT-proBNP, NYHA class) and reverse cardiac remodelling are evaluated at 6 and 12 months. Mortality and cardiac hospitalizations are recorded. The recruitment was recently completed with 384 enrolled and 153 randomized patients.
conclusionsThe study findings have the potential to inform the development of a novel adjuvant therapy to improve the prognosis of specific AS patients.
