Incidence, predictors and outcomes of subacute stent thrombosis following primary stenting for ST-elevation myocardial infarction

Background/PurposeKnowledge concerning subacute stent thrombosis (SST) following primary stenting for ST-elevation myocardial infarction (STEMI) is not widely available. We studied the incidence, predictors, and clinical outcomes of SST following STEMI.MethodsWe analyzed data from 455 consecutive patients who underwent primary stenting for STEMI. Baseline clinical characteristics, coronary angiographic features, medication and outcome were compared in patients with and without SST.ResultsSST occurred in 17 patients, and the incidence was 3.7%. Univariate predictors of SST were being a current smoker (53.0% vs. 82.4%, p = 0.01), Killip class ≥ II (38.4% vs. 58.8%, p = 0.05), no coronary re-flow after stenting (6.2% vs. 17.6%, p = 0.05) and lack of coprescription with a statin (39.5% vs. 5.9%, p
