Pre-angiography total ST-segment resolution is not a reliable predictor of an open infarct-related artery.

Background: While the cutoffs of predictive value for ST-segment elevations resolution (STSR) following thrombolysis and/or primary PCI were well documented, the impact of pre-angiography STSR has not been established yet.

Objectives: The aim of this study is to assess prognostic utility of pre-angiography STSR to predict pre-procedural TIMI flow in the infarct-related artery (IRA) and infarct size in STEMI patients undergoing primary PCI.

Methods: A prospective study was performed, including 310 patients, admitted within 12h of symptom onset and who underwent primary PCI.

Initial TIMI flow ≥ 2 and pre-angiography total ST-segment resolution predict an aborted myocardial infarction in patients undergoing primary percutaneous coronary intervention.

Background: Studies on the treatment of patients with an acute ST-segment elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI) have shown a high rate of aborted MI despite a relatively long delay from the onset of symptoms to reperfusion.

Aim: To assess predictors of aborted MI in patients undergoing primary PCI.

Methods: 310 STEMI patients referred for primary PCI within 12 h of symptom onset were included into a prospective study.

[Transient left ventricular dysfunction syndrome or an aborted myocardial infarction? Analysis of six cases].

Unlabelled: Transient left ventricular dysfunction (LVDS) is a syndrome of unknown etiology resembling acute coronary syndrome (ACS). The aim of this study was to prospectively assess the course of the acute phase of illness, recovery and prognosis after LVDS.

Material And Methods: We prospectively evaluated six women hospitalized due to suspected ACS who have had: elevated levels of troponin T the absence of critical stenoses of coronary arteries in coronary angiography, and akinesis of apical and adjacent segments in ventriculography and/or echocardiography.
