BACKGROUND: Acute transmural ischemia due to left anterior descending artery (LAD) occlusion changes precordial R and Q wave durations owing to depressed intramyocardial activation. We investigated the prognostic value of sum of precordial Q wave duration/sum of precordial R wave duration ratio (Q/R) in patients with first acute anterior myocardial infarction (AAMI) treated with primary percutaneous coronary intervention (PPCI).
METHODS: In this prospective analysis, we evaluated the no-reflow predictive value of Q/R on 403 patients with first AAMI. Patients were divided into two as no-reflow group (n=32) and control (n=371) group according to post-PPCI flow status.
RESULTS: The patients in the no-reflow group had significantly higher Q/R on admission electrocardiography (ECG) compared to patients in the control group (p<0.001). When admission ECG parameters were compared according to no-reflow prediction, Q/R was stronger than other well-accepted parameters. The best cut-off value of the Q/R to predict no-reflow was 1.08 with 76% sensitivity and 73% specificity (AUC: 0.78; 95% CI: 0.72-0.83; p<0.001).
CONCLUSION: In patients with first AAMI treated with PPCI, Q/R in admission ECG may have a role as an independent predictive marker of no-reflow.
