Resistin might not be a risk factor for carotid artery atherosclerosis in elderly Chinese males / 老年心脏病学杂志（英文版）

ABSTRACT

Objective To investigate the correlation between the serum resistin level and carotid artery atherosclerosis in elderly Chinese males. Methods The study enrolled 235 elderly Chinese males [median age 76 (range 60-97) years] scheduled for ultrasound examination of carotid artery plaque and determination of carotid artery intima-media thickness (CIMT). They were divided into carotid atherosclerotic plaque (CAP) and carotid atherosclerotic plaque-free (CAP-free) groups according to the ultrasound results. Their clinical profiles were col-lected, and the serum resistin and other blood biochemistry levels were determined.Results The CAP group was older and had a thicker mean CIMT than the CAP-free group. However, there was no difference in the serum resistin level between the groups. CIMT was positively correlated with age (r = 0.299,P< 0.001). The serum resistin level was not correlated with CIMT, even after controlling for age. Multiple linear regression analysis revealed that age (β = 0.001,P< 0.001) and body mass index (β = 0.002,P= 0.015) were significantly and posi-tively correlated with the mean CIMT. Only age [odds ratio (OR) 1.159; 95% confidence interval (CI) 1.078-1.183,P< 0.001] was associ-ated with the presence of carotid artery atherosclerotic plaque. The serum resistin level was not correlated with the mean CIMT or associated with the presence of carotid artery atherosclerotic plaque.Conclusion The results suggest that resistin might not be a risk factor for atherosclerosis in elderly Chinese males.
