The Impact of Coronary Ischemia Assessment on Outcomes in Those With Scar-Dependent Ventricular Tachycardia.
Article in Journal of cardiovascular electrophysiology, 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
backgroundGuidance and outcomes of coronary ischemia assessment (IA) in those with structural heart disease (SHD), presenting with monomorphic ventricular tachycardia (MMVT) is unclear.
objectivesTo assess the impact of IA on arrhythmic and non-arrhythmic outcomes in those with SHD.
methodsPatients presenting with MMVT over a 6-year period to a tertiary center were retrospectively analyzed. Propensity score-matched analysis was performed comparing those undergoing IA to those who did not. The primary endpoint was a composite of VT recurrence, appropriate ICD therapy, heart failure hospitalization, and death. Secondary analysis of the individual components of the composite was performed. Kaplan-Meier, univariate and multivariate analysis was performed to compare the two groups and derive predictors of poor outcomes.
resultsTwo hundred and seventeen patients (57.6% ICM) were analyzed. 55.8% underwent IA. Following propensity score-matching, 120 patients remained. At 12 months, freedom from the primary endpoint was 68.3% of those undergoing IA versus 43.3% who did not, p < 0.001, multivariate HR 0.56 (0.34-0.92). This was driven by a reduction in all-cause mortality, with a 12-month survival of 98.3% in those undergoing IA versus 86.5% in those not undergoing IA (p < 0.01). Coronary intervention was associated with a significantly higher event-free 12-month survival compared to those who did not undergo intervention (82.4% vs 51.5%, respectively, p = 0.01).
conclusionsPatients with SHD presenting MMVT who undergo an IA have significantly improved freedom from VT recurrence, appropriate ICD therapies, HF hospitalization, and death compared to those who do not, driven by a reduction in mortality.
