Descrizione dettagliata
Successful restoration of epicardial coronary artery patency in acute myocardial infarction (AMI) does not always guarantee adequate myocardial tissue perfusion or effective salvage of ischemic myocardium. In a substantial proportion of patients, microvascular dysfunction persists despite successful recanalization after percutaneous coronary intervention (PCI), limiting the expected clinical benefit of reperfusion therapy. This condition, known as the no-reflow phenomenon, is characterized by inadequate myocardial perfusion in the absence of angiographic evidence of mechanical vessel obstruction. No-reflow occurs in 2-60% of patients with ST-segment elevation myocardial infarction (STEMI) and is strongly associated with adverse ventricular remodeling, malignant arrhythmias, heart failure, and increased short- and long-term mortality.
Distal embolization of thrombus and plaque debris during PCI is a major mechanism underlying microvascular obstruction and no-reflow, emphasizing the importance of identifying high-risk coronary lesions before intervention. The SYNTAX score, an angiographic tool reflecting coronary lesion complexity, has been shown to predict clinical outcomes and the occurrence of no-reflow in patients undergoing PCI. Patients with type 2 diabetes mellitus (T2DM) represent a particularly vulnerable group, as they frequently exhibit more complex coronary lesions and a higher incidence of no-reflow.
Insulin resistance (IR) plays a central role in endothelial dysfunction, vascular inflammation, and atherothrombosis. The triglyceride-glucose (TyG) index, a simple and reliable surrogate of IR, has been associated with adverse cardiovascular outcomes and has recently been shown to predict the occurrence of no-reflow in STEMI patients with T2DM undergoing PCI.

Assessment of the association between the triglyceride-glucose (TyG) index and the SYNTAX score in patients with type 2 diabetes mellitus undergoing primary PCI for STEMI. Scale details: Minimum value: 0 Maximum value: No fixed maximum (the score is unbounded and increases according to the number, complexity, and location of coronary lesions). Interpretation: Higher SYNTAX scores indicate greater coronary artery disease complexity and worse angiographic severity. |
