BACKGROUND We investigated the prognostic value of precordial total Q wave amplitude/precordial total R wave amplitude ratio (Q/R) in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PPCI). METHODS We evaluated the in-hospital prognostic impact of Q/R on 354 patients with first acute anterior MI. Patients were stratified by tertiles of admission Q/R, clinical outcomes were compared between those groups. RESULTS In-hospital univariate analysis revealed notably higher rates of in-hospital death for patients in tertile 3, as compared to patients in tertile 1 (OR 9.7, 95% CI 2.8-33.5, p. CONCLUSION Q/R in admission ECG in patients with first acute anterior MI provide an independent prognostic marker of in-hospital outcomes.
