  • Title: [Right ventricular myocardial infarction. Prognostic significance of ST elevation in right chest leads V3R-V7R in patients with acute inferior/posterior myocardial infarction].
    Author: Andersen HR, Nielsen D, Lund O, Falk E.
    Journal: Ugeskr Laeger; 1989 Jul 31; 151(31):1984-6. PubMed ID: 2773113.
    Abstract:
    The prognostic significance of ST-elevation greater than or equal to 1 mm in right chest leads V3R-V7R during inferior/posterior acute myocardial infarction (AMI) was evaluated in 86 consecutive patients with their first inferior/posterior AMI, and compared with the prognosis for 72 patients with first anterior AMI. At follow-up, the maximum observation time was 3.0 years (mean 1.8 years). A total of 49 patients died. Using Cox multivariate analysis, ST-elevation in right chest leads during inferior/posterior AMI was found to be an independent predictor of the prognosis in patients surviving the initial ten days after infarction (n = 129). For these patients, the cumulative survival was better after inferior/posterior AMI with ST-elevation in V3R-V7R (n = 25) compared with; (1) all other infarcts (n- 104, p = 0.05), (2) inferior/posterior AMI without ST-elevation in these leads (n = 45, p = 0.09), and (3) anterior AMI (n = 59, p = 0.08).
