Abstract:
Objective To investigate the relationship of serum adiponectin (APN) with left ventricular hypertrophy (LVH) and carotid athcrosclerosis (AS),and to observe the change of serum adiponectin levels in patients with hypertension and obesity.Methods Patients with essential hypertension (50 cases) were divided into simple hypertension group (23 cases) and hypertension with obesity group(27 cases),and 45 normotensives were divided into control group (24 cases) and simple obesity group (21 cases).The levels of serum adiponectin were determined by enzyme immunoassay.Common carotid artery intima-media thickness (CCA-IMT),carotid artery diameter (CADIA) and left ventricular relevant index were measured by color doppler ultrasonography,and left ventricular mass index (LVMI) was calculated.Results In control group,simple obesity group,simple hypertension group and hypertension with obesity group,serum APN levels were decreased by turn,CADIA reduced gradually,LVMI values were increased by turn,CCA-IMT values were increased gradually (F=28.34,10.26,36.52,14.73,all P＜0.01).Correlation analysis showed that serum APN levels were significantly negatively correlated with LVMI and CCA-IMT(r=-0.870,-0.710,both P＜0.01),and were positively related with CADIA (r=0.742,P＜0.00).APN,SBP and BMI were the main influencing factors on left ventricular hypertrophy (β =-0.909,0.126,-0.053).Conclusions The presence of both hypertension and obesity may play a synergistic role in accelerating the process of left ventricular hypertrophy and atherosclerosis.Lower APN levels and/or rising BMI may accelerate occurrence and development of LVH and AS in aged patients with hypertension and obesity.
