چکیده مقاله:

Deferred versus conventional stent implantation in patients with ST-segment elevation myocardial infarction Timely primary percutaneous coronary intervention (PCI) with balloon dilatation and stent implantation is the standard treatment for patients with ST-segment elevation myocardial infarction (STEMI).Despite successful treatment of the culprit artery lesion by primary percutaneous coronary intervention (PCI) with stent implantation, thrombotic embolisation occurs in some cases, which impairs the prognosis of patients with ST-segment elevation myocardial infarction.Eligible patients (aged > 18 years) had acute onset symptoms lasting 12 h or less, and ST-segment elevation of 0∙1 mV or more in at least two or more contiguous electrocardiographic leads or newly developed left bundle branch block.composite of all-cause mortality, hospital admission for heart failure, recurrent infarction, and any unplanned revascularisation of the target vessel may differ between two groups.At one study events comprising the primary endpoint occurred in 109 (18%) patients who had standard PCI and in 105 (17%) patients who had deferred stent implantation (hazard ratio 0∙99, 95% CI 0∙76–1·29; p=0∙92). Procedure-related myocardial infarction, bleeding requiring transfusion or surgery, contrast-induced nephropathy, or stroke occurred in 28 (5%) patients in the conventional PCI group versus 27 (4%) patients in the deferred stent implantation group, with no significant differences between groups.In patients with STEMI, routine deferred stent implantation did not reduce the occurrence of death, heart failure, myocardial infarction, or repeat revascularization compared with conventional PCI. Results from ongoing randomized trials might shed further light on the concept of deferred stenting in this patient population.
