Association between triglyceride/HDL cholesterol ratio and carotid atherosclerosis in postmenopausal middle-aged women

Abstract

Abstract Background and objective The triglyceride/HDL cholesterol ratio, as a surrogate marker of insulin resistance, may be associated to presence of subclinical carotid atherosclerosis in postmenopausal women. The aim of this study was to explore this association. Patients and methods Women (last menstrual period ≥ 2 years) in primary prevention up to 65 years of age were recruited. Association between the triglyceride/HDL cholesterol (HDL-C) ratio and presence of carotid plaque, assessed by ultrasonography, was analyzed. ROC analysis was performed, determining the precision of this ratio to detect carotid plaque. Results A total of 332 women (age 57 ± 5 years) were recruited. Triglyceride/HDL-C ratio was 2.35 ± 1.6. Prevalence of carotid plaque was 29%. Women with carotid plaque had higher triglyceride/HDL-C ratios (3.33 ± 1.96 vs. 2.1 ± 1.2, p p p Conclusions In postmenopausal women in primary prevention, insulin resistance, estimated from the triglyceride/HDL-C ratio, was independently associated to a greater probability of carotid plaque. A value of such ratio greater than 2 may be used for assessing cardiovascular risk in this particular group of women.
