- Background. Echocardiographically determined left atrioventricular plane displacement (AVPD) is strongly related to prognosis in patients with chronic heart failure and in postmyocardial infarction patients. We aimed at exploring whether AVPD, unlike ejection fraction, is related to mortality in patients with stable coronary artery disease (CAD). Methods and results. Atrioventricular plane displacement was assessed by two dimensionally guided M-mode echocardiography in the four and two chamber views, in 333 consecutive patients with stable CAD and an abnormal coronary angiogram. Patients were followed up for an average of 41 months. AVPD was lower in patients who died (n = 30, 9.0 %) compared with survivors (9.0 +/- 2.2 vs. 11.5 +/- 2.1 mm, P < 0.0001). Amongst patients with prior myocardial infarction (n = 184) AVPD was 8.7 +/- 2.3 mm in those who died (n = 17) and 11.2 +/- 2.3 mm in the survivors (P < 0.0001). In patients without prior myocardial infarction (n = 149), AVPD was 9.4 +/- 2.1 (n = 13) and 11.8 +/- 1.8 mm, respectively (P < 0.0001). Age, AVPD and four other echocardiographical variables correlated significantly with prognosis in univariate logistic regression analysis. In multiple logistic regression analysis only AVPD (P < 0.0001) correlated independently with mortality. Conclusion. Echocardiographically determined AVPDis a clinically useful, independent prognostic tool in patients with stable CAD. The presence of a documented previous myocardial infarction does not influence this observation.
