Abstract

Objective: To evaluate the prognostic role of postprocedural single-lead residual ST-segment deviation for electrocardiographic evaluation of myocardial perfusion in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary angioplasty.

Design: Prospective observational clinical cohort study.

Setting: Tertiary referral centre.

Patients: 1660 patients treated with primary angioplasty for STEMI.

Main outcome measure: Mortality at 1-year follow-up.

Results: Single-lead ST-segment deviation significantly correlated with infarct size, predischarge ejection fraction, distal embolisation and myocardial blush grade 3. At 1-year follow-up, 63 patients had died. The method correlated well with 1-year mortality. At multivariate analysis, after correction for baseline demographic, clinical and angiographic variables, postprocedural single-lead ST-segment deviation showed better accuracy than residual single-lead ST-segment elevation or resolution and residual 12-lead ST-segment deviation.

Conclusions: This study showed that maximal residual ST-segment deviation in a single lead at 3 hours after the procedure is an easy and accurate predictor of 1-year mortality after primary angioplasty for STEMI.
