JUBANY, LEANDRO et al. Persistencia del supradesnivel del ST postangioplastia primaria exitosa y morbimortalidad intrahospitalaria. Rev.Urug.Cardiol. [online]. 2010, vol.25, n.2, pp.76-80. ISSN 1688-0420.

Summary Introduction: in the context of acute myocardial infarction with ST elevation, the recovery of ST segment is a reperfusion indicator after a successful primary angioplasty (PCI). Persistent ST segment elevation in patients who achieved adequate restoration of epicardial coronary flow is related to microcirculation injury. Methods: we prospectively studied all patients who underwent successful PCI in the first 12 hours of an infarction with ST elevation in Casa de Galicia’s Cardiovascular Center since 1 July 2009 to 30 September 2009. It was considered significant a ST recovery greater than or equal to 50% comparing the electrocardiogram (ECG) 1 hour after PCI with ECG prior to it. The main objective was to study the association between persistent ST segment elevation and major adverse cardiovascular events during hospitalization. Results: 55 patients were included. There was persistence of ST elevation in 27.3% (15). No association was found between ST persistence and events separately, but it was found association between the persistence and the combined end point. The cumulative incidence of events in patients without ST significant recovery is 46.6% versus 17.5% in those with ST recovery; RR 2,67 (CI 95% 1.12 to 6.32), Chi² (Mantel Haenszel) 4.80 p = 0.028. Conclusions: the persistence of ST segment elevation after successful PCI has prognostic implication in terms of in-hospital cardiovascular complications in patients with acute myocardial infarction with ST segment elevation
