Left ventricular hypertrophy and arterial stiffness in essential hypertension

Abstract

AIM: The aim of this study was to evaluate the association between an increase in arterial stiffness and the development of left ventricular hypertrophy in essential hypertension patients. MATERIALS AND METHODS: One hundred forty essential hypertension patients were included in the study. Patients were divided into two groups based on echocardiographic measurements; with left ventricular hypertrophy (n=70) and without left ventricular hypertrophy (n = 70). The criterion for hypertrophy was accepted as an intraventricular septum and posterior wall thickness in diastole of 11 mm or above. Aortic stiffness values of the patients groups were measured noninvasively by arteriography through the brachial artery. Pulse wave velocity (PWV) measurements were used as indicators of arterial stiffness. RESULTS: When compared to the group without left ventricular hypertrophy, elevated systolic blood pressure, mean blood pressure, and pulse pressure were located in the left ventricular hypertrophy group at a signifi cant level (p > 0.01). A statistically signifi cant difference was not observed in the diastolic blood pressure and pulse measurements of the groups. Pulse wave velocity, the indicator of arterial stiffness, was elevated to a signifi cant degree in the left ventricular hypertrophy group (p > 0.01). While a positive correlation was found between pulse wave velocity and left ventricle mass index, microalbuminuria, high sensitive C-reactive protein (Hs-CRP), and left ventricle enddiastolic volume, a negative correlation was found between pulse wave propagation velocity and left ventricle E/A. CONCLUSIONS: In conclusion, pulse wave analysis is a valuable method for predicting cardiac hypertrophy in essential hypertension (Tab. 6, Ref. 25). Text in PDF www.elis.sk.

Senescent cells: a therapeutic target for cardiovascular disease

“…The normal aging heart employs several mechanisms to maintain resting systolic function and ejection fraction despite increased afterload (56). Structurally, the left ventricle (LV) thickens to normalize tension across the LV wall but does not increase in mass (48), instead shortening across the long axis.…”

Arterial Stiffness: Pathophysiological and Genetic Aspects

“…Thus, arterial stiffness is associated with increased post-load of the left ventricle and decrease in mean coronary perfusion pressure 10 , which occurs mainly in the diastole. These changes result in hypertrophy of the left ventricle 11 , worsening of coronary ischemia 12 and increased stress in the vascular wall 13 which, in turn, may facilitate the rupture of atherosclerotic plaques. …”

The evaluation of arterial stiffness of essential hypertension and white coat hypertension in children: a case-control study

“…Thanks to the evaluation of arterial stiffness in patients with essential hypertension, much information related to cardiovascular disease risks was revealed. [22][23][24] Nonetheless, there a large number of studies involving children have been carried out. In once such study conducted by Liu et al, arterial stiffness was assessed in hypertensive children and no significant difference was determined compared with the control group.…”
