Novel insights into no-reflow post-PCI: The predictive value of coronary sinus hemodynamics.
Article in Global cardiology science & practice, 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
backgroundCoronary no-reflow (NR) represents a significant complication associated with increased mortality in patients with acute myocardial infarction undergoing percutaneous coronary intervention (PCI). The identification of novel predictors for early recognition and timely management warrants investigation in order to improve patient outcomes.
aimThe coronary sinus has emerged as a versatile tool in various diagnostic and therapeutic interventions. Accordingly, we aimed to measure coronary sinus filling time (CSFT) in patients who developed NR during primary PCI and evaluate its potential role in NR prediction.
methodsA total of 180 patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI were enrolled in this study. Patients were stratified into two groups based on the occurrence of no-reflow phenomenon: the NR group (
resultsNR developed in 38.3% of patients. CSFT was significantly prolonged in the NR group compared with the normal reflow group (69.13 ± 12.20 vs. 60.19 ± 23.22 frame counts,
conclusionCoronary sinus filling time represents an underutilized yet potentially valuable tool for the prediction and early identification of the no-reflow phenomenon during PCI. Our findings suggest that prolonged CSFT correlates with impaired microvascular perfusion and may serve as an early physiological indicator of impending no-reflow.
