[Deferred versus immediate stenting in patients with ST - segment elevation myocardial infarction and residual large thrombus burden reclassified in the culprit lesion].

Background: Reclassification of a large thrombus burden is an independent predictor of major adverse cardiac events and no-reflow in patients with ST- segment elevation myocardial infarction (STEMI). Patients with a greater residual thrombus burden have worse microvascular dysfunction and greater myocardial damage.

Methods: A retrospective analysis was performed on 833 STEMI patients who underwent primary percutaneous coronary intervention.
