Objective To investigate the relationship between body mass index(BMI) and carotid plaque in population at high risk for stroke. Methods The clinical data of 546 cases at high risk for stroke in our hospital were analyzed. Color Doppler was used to examine the number of carotid plaque. The correlation between BMI level combined with other risk factors and carotid plaque. Results High BMI was the independent risk factor for carotid plaque formation(OR = 1.653,95% Cl: 1.063~2.572, P =0.026). The formation rat...
