Ascending aorta dilatation reduces the influence of elevated pulse pressure on left ventricular hypertrophy: findings from a Chinese elderly hypertensive population.

ABSTRACT:

Objective

To determine the role of ascending aorta dilatation in the relationship between pulse pressure (PP) and left ventricular (LV) hypertrophy.

Methods

A total of 1556 Chinese elderly hypertensive patients were retrospectively studied. Transthoracic echocardiography was used to obtain the aortic and cardiac structure measurements. In addition, brachial blood pressure was measured, and total arterial compliance, systemic vascular resistance, arterial elastance, and end-systolic LV elastance were calculated. The participants were divided into four groups according to the status of ascending aortic diameter and PP.

Results

LV mass index increased in succession in the four groups, i.e., the group with the normal aorta and lower PP, with the normal aorta and higher PP
