Randomized Controlled Trial Multicenter StudyRelationship between ST-segment recovery and clinical outcomes after primary percutaneous coronary intervention: the HORIZONS-AMI ECG substudy report.
In patients with ST-segment elevation myocardial infarction undergoing thrombolytic therapy, the degree of ST-segment resolution (STR) correlates with long-term cardiovascular mortality. The long-term predictive value of STR after primary percutaneous coronary intervention (PCI) is less well understood. We sought to determine the long-term prognostic value of STR after primary PCI in ST-segment-elevation myocardial infarction. ⋯ In this large international study, absent STR 60 minutes after primary PCI was present in ≈1 in 5 patients with ST-segment-elevation myocardial infarction and was a significant independent predictor of major adverse cardiovascular events and target vessel revascularization at 3 years.
