Prognostic Value of Myocardial Blush Grade in Patients With ST-Segment Elevation Myocardial Infarction (STEMI) Undergoing Primary Percutaneous Coronary Intervention (PCI): Association With Reperfusion Success and In-Hospital Outcomes.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMyocardial blush grade (MBG) is a simple angiographic tool for assessing microvascular perfusion in patients with ST-segment elevation myocardial infarction (STEMI). While restoration of epicardial flow by primary percutaneous coronary intervention (PCI) is critical, microvascular reperfusion determines true myocardial salvage. Limited data are available from Pakistan regarding the prognostic value of MBG in predicting in-hospital outcomes.
objectiveThis study aimed to evaluate the prognostic significance of MBG in STEMI patients undergoing primary PCI, with emphasis on reperfusion success and in-hospital adverse events.
methodsThis prospective observational study was conducted at Lady Reading Hospital Medical Teaching Institution, Peshawar, Pakistan, from January to December 2024. A total of 200 consecutive STEMI patients treated with primary PCI were included. MBG was assessed by two independent interventional cardiologists, and patients were stratified into low MBG (0-1) and high MBG (2-3) groups. Baseline demographics, angiographic findings, and in-hospital outcomes were compared using appropriate statistical tests. Multivariate logistic regression was applied to adjust for confounders.
resultsAmong 200 patients, 80 (40%) had MBG 0-1 and 120 (60%) had MBG 2-3. Patients with low MBG were older, were more likely to present with anterior wall myocardial infarction
conclusionMBG is a powerful and independent predictor of reperfusion success and in-hospital outcomes in STEMI patients undergoing primary PCI. Its routine use in clinical practice can aid in early risk stratification, especially in resource-limited settings such as Pakistan. Future multicenter studies with long-term follow-up are warranted to confirm these findings.
