Percutaneous Revascularization in Infarction With Late Presentation and Absence of Viability: Effects on Left Ventricular Remodeling and Contractility

The purpose of this study is to evaluate whether late recanalization in patients with ST elevation myocardial infarction (STEMI) without Viability on Cardiovascular Magnetic Resonance can reduce the reverse remodeling through the reduction of the End Systolic Volume (ESV) at 6 months and through the improvement in segmental contractility of infarcted related artery at MRI.
