Özet
Objective: Ascending aortic aneurysms (AAA) are a leading cause of morbidity and mortality. Nevertheless, their effects on global cardiac functions are yet to be fully understood. Myocardial performance index (MPI) has been widely used to quantitatively assess myocardial functions. The aim of this study was to evaluate left ventricular (LV) functions in patients with AAA using tissue Doppler (TD) echocardiography and MPI in addition to conventional echocardiographic methods. Methods: Fifty patients with AAA (33 men, 17 woman; mean age 55.5+/-7.90 years) were included, and 106 patients without aortic dilatation (mean age 54.1+/-8.18 years) were included as the control group. LV systolic and diastolic functions were analyzed using 2-dimensional, M-mode, and TD echocardiography. Results: Patients with AAA had significantly higher MPI (0.5+/-0.04 vs 0.4+/-0.05, p<0.001), TD-MPI (0.5+/-0.02 vs 0.4+/-0.03, p<0.001), and reduced aortic elasticity, as indicated by reduced aortic distensibility (AD) (1.7+/-1.27 vs 3.1+/-1.25, p<0.001). Multivariate linear regression analysis showed that TD-MPI was independently correlated with reduced aortic distensibility (B=-0.006, p=0.019, 95% confidence interval,-0.011 to -0.001). Conclusion: MPI and TD-MPI indicated impairment of global cardiac functions in patients with AAA, which may be attributed to reduced aortic elasticity.
