ST-segment resolution assessed immediately after primary percutaneous coronary intervention correlates with infarct size and left ventricular function in cardiac magnetic resonance at 1-year follow-up.
BACKGROUND
Little is known about the predictive value of electrocardiographic ST-segment resolution (STR) assessed immediately after primary percutaneous coronary intervention (PCI). The aim of the study was to analyze the value of STR and maximum single-lead ST-segment elevation assessed immediately after primary PCI in prediction of infarct size and left ventricular function in cardiac magnetic resonance (CMR) at 1-year follow-up.


RESULTS
A total of 28 patients with anterior wall ST-segment elevation myocardial infarction treated with primary PCI entered the study. There was a significant correlation of STR and maximum single-lead ST-segment elevation assessed immediately after primary PCI and CMR infarct size and left ventricular function after 1 year. When analyzed according to standard optimal reperfusion cutoff (70% for STR and 1 mm for single-lead elevation), both electrocardiographic parameters were also good predictors of CMR infarct size and left ventricular function after 1 year.


CONCLUSIONS
ST-segment resolution and the single-lead maximum ST-segment elevation assessed immediately after primary PCI for ST-segment elevation myocardial infarction are good predictors of infarct size and left ventricular function in 1-year follow-up.
