Abstract
The relation between left ventricular (LV) hypertrophy and LV function is well known. However, less is known about the vascular changes influenced by LV geometry. We sought to investigate the relationship of LV geometry to carotid arterial and LV function. A total of 476 hypertensive patients were prospectively recruited. All subjects underwent echocardiography and carotid ultrasound. LV geometry is categorized into four groups according to relative wall thickness (RWT) and LV mass index (LVMI). Concentric LV geometry was associated with increased carotid intima-media thickness (IMT), β-stiffness, and lower strain. All of the carotid parameters showed a stepwise change according to RWT of LV, whereas LV function was worse in hypertrophic geometry, as reflected by significantly lower systolic mitral annular velocity, higher left atrial volume index and E/E′ ratio (P<0.001). By multivariate analysis after adjustment for clinical and laboratory parameters, IMT was independently associated with RWT, whereas myocardial function was independently associated with LVMI. Carotid arterial function and IMT showed worse values in concentric geometry, whereas LV systolic and diastolic function were worse in hypertrophic geometry, suggesting a discrepancy between carotid arterial and LV function in hypertensive patients.
