Myocardial no-reflow may negate the benefit of urgent coronary revascularization in patients with acute ST-elevation myocardial infarction (STEMI). Among its pathogenetic mechanisms, distal embolization is of prominent importance and several studies have shown that a high coronary thrombotic burden is associated with distal embolization. We...

Background No reflow after primary percutaneous coronary intervention is a dynamic process and its reversibility may affect left ventricular (LV) remodeling. We aimed at assessing in-hospital evolution of angiographic no reflow, predictors of its reversibility, and its impact on LV function at follow-up (FU). Methods Fifty-three consecutive...

Background Angiographic and electrocardiographic (ECG) indexes of microvascular obstruction (MVO) have been described. We aimed at assessing by cardiac magnetic resonance (CMR) anatomical features underlying concordance between them. Methods Forty-one patients were enrolled. Patients presented with neither angiographic nor ECG indexes of MVO...

Aims Thromboxane A2 (TXA2) is a key mediator of platelet activation and aggregation, and an important mediator of platelet-induced coronary artery constriction. We sought to investigate whether baseline plasma levels of TXA2 are associated with coronary no-reflow after primary percutaneous coronary intervention (PPCI). Methods and results A...
