This comprehensive review synthesizes current knowledge on the pathophysiology, diagnosis, and treatment of coronary no-reflow, highlighting future directions like AI-based predictive modeling.
The coronary no-reflow phenomenon remains a daunting and unresolved barrier during percutaneous coronary procedures, especially for acute coronary syndrome. Despite successful epicardial artery patency restoration, decreased microvascular perfusion leads to unfavorable outcomes such as ventricular remodeling, progression of heart failure, and increased mortality. This review provides a new, integrative informative perspective by combining multifactorial pathophysiology, which includes systemic inflammation, thrombogenicity, ischemia-reperfusion injury, and distal embolization, with advances in diagnostic imaging, such as cardiac magnetic resonance and computed tomography. Therapeutic options, including antithrombotic regimes, vasodilators, and mechanical adjuncts, are evaluated in the context of developing debates and unmet clinical needs. Importantly, we provide feasible future directions for artificial intelligence-based predictive modeling and targeted microvascular treatments. This comprehensive review fills a significant gap, aiming to inform personalized approaches and improve both short- and long-term outcomes in this high-risk patient population.
