Background

Inpatients presenting with ST-elevation myocardial infarction (STEMI) andsuccessfully achieving TIMI 3 flow after urgent percutaneous coronaryintervention (PCI), myocardial perfusion remains heterogeneous. The myocardialblush grade (MBG) provides an angiographic marker of microvascular reperfusion,but its prognostic significance for in-hospital mortality is less well established.

Methods

All consecutive patients presenting with STEMI diagnosis and undergoing urgent PCI in a major tertiary care center in Tunisia from 2020 to 2024 were included prospectively. Patients were categorized according to final MBG: low MBG (grade 0–1, n = 26) and high MBG (grade 2–3, n = 332). Primary endpoint was in-hospital mortality. MBG was included in a multivariate analysis model to determine independent predictors of in-hospital death.

Results

A total of 358 patients were included. Mean age was 59.5 ¡¾ 11.6 years and 89.7% were male. Prevalence of diabetes, hypertension and tobacco smoking was 39.4%, 30.7% and 72.1%,respectively. Patients with low MBG had significantly lower mean left ventricular ejection fraction compared with those with high MBG (43.0% ¡¾ 11.9vs. 49.8% ¡¾ 10.1, p = 0.001). In multivariable logistic regression, independent predictors of in-hospital mortality were cardiogenic shock at admission (OR26.8, 95% CI 4.9–144.2, p < 0.001), three-vessel disease (OR 5.5, 95% CI1.2–25.9, p = 0.031), no-reflow phenomenon (OR 8.1, 95% CI 1.1–60.9, p =0.043), and pulmonary edema at admission (OR 6.2, 95% CI 1.6–24.2, p = 0.009). Importantly, a high MBG (2–3) was independently protective against in-hospital mortality (OR 0.07, 95% CI 0.02–0.31, p < 0.001).

Conclusion

Among STEMI patients achieving TIMI 3 flow after urgent PCI, a low MBG (0–1) is associated with impaired left ventricular function and higher in-hospital mortality. Final MBG is an independent and powerful predictor of short-term prognosis, underscoring the importance of myocardial perfusion beyond epicardial flow restoration.
