Atrio-Ventricular Plane Displacement in Ischemic Heart Disease

Background- Whether atrio-ventricular plane displacement (AVPD) in echocardiography findings may help to diagnose ischemic heart disease (IHD) in the presence of normal systolic function is not clear. This study aimed to assess the relationship between AVPD and ischemic heart disease (IHD) in a group of IHD patients. Method- One hundred two outpatients (65 male and 37 female) aged 58.9±11.4 were examined for IHD by echocardiography, stress test and angiography, and 61 patients were found to have IHD. Echocardiographic findings, including AVPD, LVEF and RWMA, were compared in normal and IHD patients. Results- Comparison of echocardiography findings in the ischemic patients to the normal subjects showed that the subjects with IHD had significantly lower AVPD, LVEF and higher RWMA. Results of a logistic regression analysis indicated that AVPD was an independent predictor of IHD (OR=0.61, 95%CI= 0.46-0.79). Conclusion- These data suggested that low AVPD was associated with increased risk of IHD. AVPD may help diagnose IHD when more sophisticated techniques are not available and/or applicable
