Trends in Conventional Heart Failure Therapy in a Real-World Multinational ATTR-CA Cohort.
Article in Journal of cardiovascular development and disease, 2025. 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
backgroundConventional HF treatment in transthyretin cardiac amyloidosis (ATTR-CA) resulting in restrictive cardiomyopathy is debated due to absent trial evidence in this specific sub-population of heart failure (HF) patients. Current European Society of Cardiology guidelines recommend the use of diuretics and mineralocorticoid receptor antagonists (MRAs). However, beta-blockers (BBs) and angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARBs) are often discontinued due to hypotension or bradycardia. This study assesses real-world HF treatment patterns and their impact on survival in a multinational ATTR-CA cohort.
methodsA retrospective analysis of 794 ATTR-CA patients examined baseline BB, ACEi/ARB, and MRA prescriptions. The cohort was divided based on guideline publication dates.
resultsPatients were predominantly male (73.2%) with a median age of 78 years. Prescription of diuretics (52.8%) and disease-modifying therapy (44.9%), mostly tafamidis, was common. BBs (43.7%) and ACEi/ARBs (41.2%) were prescribed more often in patients with higher NYHA class, elevated NT-proBNP, and more comorbidities. Blood pressure and heart rate were similar regardless of BB or ACEi/ARB use. BB prescription and combination therapy with BB and ACEi/ARB increased over time. Neither BB nor ACEi/ARB use significantly impacted mortality when analyzed in a multivariate Cox proportional hazard regression.
conclusionsUse of BBs and ACEi/ARBs has increased over time, particularly in advanced-stage ATTR-CA patients, and although these therapies appear to be reasonably tolerated, survival was not significantly altered.
