Abstract
Nondipper hypertension is associated with increased cardiovascular morbidity and mortality. Speckle tracking echocardiography is a novel and promising tool for detecting early changes in left atrial (LA) myocardial dysfunction. Our aim was to evaluate the LA mechanical function and stiffness in nondipper hypertensive patients by two-dimensional speckle tracking echocardiography strain parameters. This study included 80 hypertensive patients. Hypertensive patients were divided into two groups: 50 dipper patients (29 male, mean age 51.5 ± 8 years) and 30 nondipper patients (17 male, mean age 50.6 ± 5.4 years). LA volume indices, mitral annular velocities, and global longitudinal LA strain were measured. The ratio of E/e' to LA strain was used as an index of LA stiffness. Patients with nondipper hypertension showed increased LA volume indices and decreased LA global strain (25.3 ± 5.5 vs. 39.6 ± 9.9%, P < 0.001). LA stiffness was increased in patients with nondipper than in the dipper subjects (0.41 ± 0.15 vs. 0.19 ± 0.14, P < 0.001), and LA strain and LA stiffness were related to LA volume indices. Patients with nondipper hypertension have decreased LA global strain and increased stiffness, in comparison with dipper group. LA sti...Continue Reading
