- Abstract
Background: The prognostic value of ST-segment elevation in lead V1 (STE in V1) in anterior ST-segment elevation myocardial infarction (STEMI) has not been elucidated., Methods: We performed a retrospective analysis of 190 consecutive first anterior STEMI patients. STE in V1 ≥0.1mV was recorded. Major adverse cardiac events (MACE) were defined as a composite of all-cause death, recurrent myocardial infarction, or target vessel revascularization., Results: Among 190 patients, 42 patients did not have STE in V1. The patient without STE in V1 had a higher peak creatine kinase value and a higher incidence of 1-year MACE (36% vs. 13%, p<0.001), driven by a higher mortality (24% vs. 5%, p<0.001). The absence of STE in V1 was an independent predictor for 1-year MACE (odds ratio 3.16; 95% confidence interval 1.28-7.83; p=0.01)., Conclusion: The absence of STE in V1 was an independent predictor for worse long-term outcomes in patients with first anterior STEMI., (Copyright © 2015 Elsevier Inc.
