Abstract
- Mental stress-induced myocardial ischemia is common and a prognostic factor of adverse cardiovascular outcomes in patients with coronary artery disease (CAD). The present study aimed at examining associations between mental stress-induced myocardial annular velocity (MAV) and cardiovascular outcome in patients with CAD. MAV, specifically, diastolic early (e'), diastolic late (a'), and systolic (s') velocities were obtained at rest and during mental stress testing in 224 patients with clinically stable CAD. Using Cox regression models, age, sex, and baseline-adjusted mental stress-induced MAV measures were examined as predictors of a priori defined composite event term that comprised all-cause mortality and/or nonfatal cardiovascular events, resulting in an unplanned hospitalization (major adverse cardiovascular events [MACE]). Median follow-up was 4 years. The sample was predominantly male, Caucasian with New York Heart Association functional class I and a mean age of 63 ± 10.2 years. MS-induced changes in e' (hazard ratio [HR] = .73) and s' (HR = .73) were significant (p <0.05) predictors of MACE, and the change in a' (HR = .74) was marginal (p = 0.05). The pattern of the relation for each MAV measure was such that patients with a greater decrease in e' and/or s' velocity had a higher probability of experiencing an MACE, and the association of the change in a' and MACE was marginal (p = 0.05), but the same tendency. The associations between MS-induced values of e' and a' for MACE were independent of resting levels. Mental stress-induced MAV changes independently predict an adverse cardiovascular outcome in patients with stable CAD.<br /> (Copyright © 2017 Elsevier Inc. All rights reserved.)
