Long Term Cardiovascular Outcome Based on Aspirin and Clopidogrel Responsiveness Status in Young ST-Elevated Myocardial Infarction Patients

Impact of Stress Hyperglycemia on the Timing of Complete Revascularization in Non-diabetes Patients with ST Elevation Myocardial Infarction and Multivessel Disease

Background: Stress hyperglycemia (SHG) is related to an increased risk of mortality in diabetic patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). However, data are limited in non-diabetic patients especially in patients with multivessel disease (MVD). Methods and Results: In this retrospective study, 742 non-diabetic patients with STEMI and MVD were divided into SHG group and non-SHG group. The overall incidence of SHG was 24.9%. The incidence of no-reflow (NR) phenomenon (18.4% vs 11.8%; P = .024) and in-hospital mortality (1.6% vs .2%; P = .020) in SHG group were significantly higher than those in non-SHG group. SHG was associated with 30-day MACE (hazard ratio, 4.265; 95% confidence interval (CI), 1.354-13.439; P = .013), but not 1-year. Multivariate logistic analysis showed that SHG (odds ratio: 1.691, 95% CI: 1.072-2.667, P = .024) was an independent predictor of NR. If complete revascularization (CR) was performed during PPCI, the incidence of NR would be significantly higher. Conclusion: In non-diabetic patients with STEMI and MVD, SHG is associated with increased SF-NR and short-term adverse events, and CR during PPCI further increases the risk of NR.
