Predictors of IVO are not well established. Methods:149 patients were studied at rest and during DSE. The normal range of the left ventricular outflow tract (LVOT) velocities was investigated in 68 healthy patients. Results: 19 patients (13%) developed IVO (peak LVOT velocity > 271 cm/sec). A significant linear correlation was observed between peak LVOT velocity during DSE and the following rest parameters: LV end-diastolic dimension (r=−0.20,P = 0.018), LV end-systolic dimension (r = − 0.27, P = 0.001), relative wall thickness (r = 0.23, P = 0.006), shortening fraction (r = 0.24, P = 0.004), LVOT diameter (r = − 0.20, P = 0.023) and LVOT velocity (r = 0.29, P < 0.0001). Only relative wall thickness (P = 0.012) and LVOT diameter (P = 0.027) were independent predictors of IVO. As a dichotomous variable, a relative wall thickness ≥0.44 was the only independent predictor of IVO (OR 5.7, 95% CI 1.6–20, P = 0.006), with sensitivity,specificity, negative predictive value, and positive predictive value of 77%, 62%, 95%, and 21%,respectively, and global accuracy of 63% (area under the ROC curve = 0.7). IVO was significantly associated with general cardiovascular symptoms (P = 0.0006) and with chest pain (P = 0.008). Conclusions: Relative wall thickness and LVOT diameter were independent predictors of obstruction. As a dichotomous variable, a relative wall thickness ≤ 0.44 was the only independent predictor of dynamic IVO.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-06-20T20:23:56Z No. of bitstreams: 1 (80)j.1540-8175.2009.00953.x.pdf: 243845 bytes, checksum: 4579fcb65cc1c84c054d799bb1b2b9b7 (MD5)Made available in DSpace on 2012-06-20T20:23:56Z (GMT).
