Abstract:
Objective:To compare the distribution characteristics of left ventricular configuration in Chinese adult patients with hypertension under Chinese and international standard using echocardiography.
Methods:A total of 201 patients with primary hypertension were included in the study.Left ventricular end systolic left atrial diameter (LAD), ascending aortic diameter (AO), left ventricular end diastolic diameter (LVDd), left ventricular posterior wall thickness (PWTd) and ventricular septal thickness (IVSd) were measured and then relative wall thickness (RWT), left ventricular mass (LVM), left ventricular mass index (LVMI) were calculated. Left ventricular systolic left atrial volume (LAV) was measured by Simpson′s biplane method and left atrial volume index (LAVI) was then calculated. Ganau classification was done according to Chinese and international standard respectively. The differences of left ventricular configuration in hypertension were compared.
Results:According to the Chinese standard, the analytic results of left ventricular configuration showed that there were 103 cases (51.2%) in normal configuration (NG) group, 28 cases (13.9%) in concentric remodeling (CR) group, 52 cases (25.9%) in eccentric hypertrophy (EH) group and 18 patients (9.0%) in hypertrophic (CH) group, respectively. Whereas, according to the international standard, there were 47 cases (23.4%) in NG group, 93 cases (46.3%) in CR group, 18 cases (8.9%) in EH group and 43 cases (21.4%) in CH group.Each group in the configuration analysis had significant difference between Chinese and international standard (P<0.01). Patients with left atrial enlargement according to the Chinese and international standard had statistical difference in the EH and CH groups (P<0.05).
Conclusions:Analysis of left ventricular configuration according to the Chinese and international standard has significant difference. According to Chinese standard, it may be more accurate to reflect the changes of left ventricular configuration in Chinese hypertensive population, so as to evaluate the changes of left heart structure and function more accurately.
