Efficacy of ivabradine in heart rate reduction after cardiac transplantation: Systematic review and meta-analysis.
Article in World journal of cardiology, 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
backgroundPersistent sinus tachycardia affects up to 40% of patients after heart transplantation and is linked with graft dysfunction, impaired diastolic filling, and increased morbidity. Conventional rate-limiting therapies such as beta-blockers and calcium channel blockers are quite often contraindicated due to risks of bradyarrhythmia or hypotension. Ivabradine, a selective I(f) channel inhibitor, reduces heart rate (HR) without negative inotropic or hypotensive effects.
aimTo evaluate the efficacy and safety of ivabradine in heart transplant recipients.
methodsA comprehensive search of PubMed, EMBASE, Scopus, Cochrane Library, and Google Scholar was conducted from inception to April 15, 2025. Eligible studies evaluated ivabradine in heart transplant recipient
resultsOf 415 records identified, four studies comprising 264 patients (126 ivabradine, 138 control) met the inclusion criteria. Ivabradine significantly reduced resting HR compared with controls (MD = -11.06 beats per minute; 95%CI: -19.50 to -2.62;
conclusionIvabradine reduces HR effectively in heart transplant recipients without added adverse outcomes, supporting its use as safe and well-tolerated alternative when conventional agents are unsuitable. Despite potential clinical benefit, small sample size and heterogeneity the need for larger randomized trials to confirm long-term outcomes and establish ivabradine's role in post-transplant care.
