Lipid Changes Around the Final Menstrual Period Predict Carotid Subclinical Disease in Postmenopausal Women.

ABSTRACT: Atherogenic changes in lipids occur among women around the time of the natural menopause, that is, within 1 year of the final menstrual period (FMP). We investigated whether lipid changes around the FMP are related to carotid intima-media thickness, interadventitial diameter, and plaque in postmenopausal women.A total of 863 natural postmenopausal women with no history of heart attack or stroke underwent carotid ultrasound scans at follow-up year 12 or 13 of the Study of Women's Health Across the Nation. Estimates of their annual change in lipids were segmented into the year before and after the FMP, before the year before FMP, and 1 year after FMP. Multivariate analyses were adjusted for sociodemographic characteristics, time from FMP to scan, baseline body mass index and systolic blood pressure, and use of medications for hypertension and diabetes mellitus at the scan.Smaller increases in high-density lipoprotein cholesterol and apolipoprotein A1 within 1 year of the FMP were related to greater interadventitial diameter, ? (SE)=-0.036 (0.015), P=0.02, and ? (SE)=-0.035 (0.013), P=0.006, respectively. Greater increases in low-density lipoprotein cholesterol within 1 year of FMP were related to greater likelihood of plaque scores ?2, odds ratio, 1.071; 95% confidence interval, 1.018-1.127; P=0.009. Magnitude of associations was reduced but remained significant with further adjustment for premenopausal lipid levels. The difference in probability of elevated plaque scores was 50% between those in the highest and lowest low-density lipoprotein cholesterol change tertiles.Changes in lipids as women approach the FMP provide useful clinical information for understanding postmenopausal carotid indices.

Project description:ObjectivesAlthough carotid artery intima media thickness (CIMT) is a widely used determinant of subclinical atherosclerosis, gray-scale median of the intima-media complex (IM-GSM) of the common carotid artery is a relatively novel measure of echogenicity reflecting composition of the arterial wall. It is important to compare cardiovascular disease (CVD) risk factor correlates across CIMT and IM-GSM to determine whether these measures reflect distinct aspects of atherosclerosis.MethodsBaseline information from a completed randomized clinical trial of 643 healthy postmenopausal women without clinically apparent CVD was included in this cross-sectional study. The women were on average ± SD 61 ± 7 years old, and predominantly non-Hispanic White. CIMT and IM-GSM were measured by high-resolution B-mode ultrasonogram in the far wall of the right common carotid artery. CVD risk factors including age, race, body mass index (BMI), smoking, weekly hours of physical activity, systolic (SBP) and diastolic blood pressure (DBP), lipids, glucose, and inflammatory markers were measured at baseline. Linear regression models were used to assess associations of CVD risk factors with CIMT and IM-GSM. Multivariable models included groups of risk factors added one at a time with and withoutbasic demographic factors (age, race, BMI, physical activity) with model R2 values compared between CIMT and IM-GSM.ResultsIn multivariable analysis, age, Black race, BMI, SBP, and DBP were associated with CIMT (all P < .05), whereas age, Hispanic race, BMI, SBP, physical activity, LDL-cholesterol, and leptin were correlates of IM-GSM (all P < .05). Adjusted for age, race, BMI, and physical activity, the R2 value for SBP was greater for CIMT association, whereas R2 values for lipids, glucose, inflammatory markers, and adipokines were greater for IM-GSM associations.ConclusionsCIMT and IM-GSM assess different attributes of subclinical atherosclerosis. Integrating both measures may provide improved assessment of atherosclerosis in asymptomatic individuals.
