Strategies of Revascularization in Patients With ST-segment Elevation Myocardial Infarction (STEMI) and Multivessel Disease

Complete Revascularization Or streSS Echo in Patients With Multivessel Disease and ST-segment Elevation Acute Myocardial Infarction

Multivessel disease has been reported to occur between 40 and 60% of patients with ST-segment elevation myocardial infarction (STEMI) and has been associated to a worse prognosis. Multivessel revascularization offers a myriad of potential advantages as enhance of the collateral blood flow, greater myocardial salvage, the stabilization of other lesions that can be potentially vulnerable, and the achievement of a complete revascularization, factor that is associated with a better prognosis. On the other hand, the prolongation of procedural duration, the hazard of contrast induced nephropathy and the peri-procedural complications can limit the widespread of this practice. To date, very few observational studies have focused in the multivessel revascularization with disparity of results. Whereas ones have observed an increase of adverse cardiovascular events and thus not recommend it, others have shown neutral results. Stress echocardiography has been shown to be an adequate technique for the diagnosis of coronary artery disease and could be an appropriate tool for selecting the lesions that need to be revascularized because they induce large areas of ischemia. However, this technique has also limitations like the high operator-dependence. Therefore, the investigators sought to study if the complete multivessel revascularization of patients with STEMI treated by means of primary percutaneous coronary intervention (PCI) has an impact on prognosis compared to a strategy of treating only those non-culprit lesions that produce large areas of ischemia in a stress test.

After a successful primary PCI these patients will undergo complete revascularization of non-culprit lesions in a staged procedure during the index admission

after successful primary PCI, this group will undergo a stress echo to evaluate the significance of non-culprit lesions. If large area of ischemia is demonstrated, the artery supplying that are will be revascularized.
