Is Carvedilol Effective in Preventing and Modulating Concentric Cardiac Remodelling? A Comprehensive Systematic Review and Meta-Analyses.

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
Background: Carvedilol, commonly used to treat hypertension and known for its vasodilatory and pleiotropic effects, has been studied in various patient populations. However, its specific impact on diastolic dysfunction and heart failure with preserved ejection fraction (HFpEF) remains unclear. Aim: The aim of the study is to evaluate carvedilol's efficacy in preventing concentric cardiac remodelling in at-risk individuals and modulating it in patients with HFpEF. Methods: In adherence to PRISMA guidelines, we searched PubMed and ScienceDirect up to March 2024 using terms related to carvedilol and HFpEF. We included randomised controlled trials and prospective cohort studies published in English. Outcomes include changes in natriuretic peptides and echocardiography parameters of diastolic function. Exclusion criteria encompassed non-English studies, nonhuman studies and studies not using carvedilol or exclusively involving HFrEF patients. Risk of bias was assessed using the revised Cochrane tool and Newcastle-Ottawa Scale. Data synthesis was performed using a random-effects meta-analysis with sensitivity analyses and a leave-one-out procedure to explore heterogeneity. Results: Eighteen studies involving 2233 participants were included. Various populations were included: those with HFpEF or undergoing cardiotoxic chemotherapy. Meta-analysis did not reveal significant effects of carvedilol on echocardiography parameters such as E/A ratio (mean difference 0.04, 95% CI -0.01 to 0.08), E/e' ratio (mean difference -0.50, 95% CI -1.39 to 0.39) and LVMI (mean difference 0.21, 95% CI -3.13 to 3.55), with substantial heterogeneity observed in LVEF, LVMI and BNP. Conclusion: Carvedilol does not significantly impact diastolic dysfunction across various populations. However, the diversity of study populations and outcomes contributes to the heterogeneity of results.
