ABSTRACT In Taiwan, the Chin-Shan Community Cardiovascular Cohort (CCCC) was assessed prospectively to determine whether the changes in cardiovascular risk factors for women age 45--54 years are due to menopause. The average paired percentage changes that occurred between baseline (1990-1991) and follow-up (4 years later) in fasting serum lipids were compared in three groups of women including groups of 59 and 224 who were pre- and postmenopausal, respectively, and a group of 118 who had spontaneously stopped menstruating. Postmenopausal women had the least gain in body mass index (BMI), whereas, mainly premenopausal women had increased systolic blood pressure (P<0.05). All women had elevated total cholesterol (TC) levels, with the greatest elevation in women transitioning into menopause (P<0.001). Low-density lipoprotein cholesterol (LDL-C) levels increased before and during the transition to menopause, but decreased after menopause (P<0.01). Age had significant association with changes in TC, triglyceride (TG) and LDL-C levels, whereas BMI had significant association with changes in TG, LDL-C, and high-density lipoprotein cholesterol (HDL-C) levels (P<0.05). After controlling for age and BMI, only differences in TC remained significant, with the greatest gain in women who stopped menstruating (12.9%) followed by pre- (6.5%) and postmenopausal women (4.8%). Changes in both systolic and diastolic blood pressures, and TG and HDL-C levels were not significantly different, but HDL-C levels declined between 11.5 and 14.7% in all groups. This study suggests an unfavorable effect of menopause on lipid metabolism, especially on the TC level, which was predominantly elevated during the transition to menopause. The decline of HDL-C is of concern.

    ABSTRACT: Non-communicable diseases such as cancer, atherosclerosis and diabetes are responsible for major social and health burden as millions of people are dying every year. Out of which, atherosclerosis is the leading cause of deaths worldwide. The lipid abnormality is one of the major modifiable risk factors for atherosclerosis. Both genetic and environmental components are associated with the development of atherosclerotic plaques. Immune and inflammatory mediators have a complex role in the initiation and progression of atherosclerosis. Understanding of all these processes will help to invent a range of new biomarkers and novel treatment modalities targeting various cellular events in acute and chronic inflammation that are accountable for atherosclerosis. Several biochemical pathways, receptors and enzymes are involved in the development of atherosclerosis that would be possible targets for improving strategies for disease diagnosis and management. Earlier anti-inflammatory or lipid-lowering treatments could be useful for alleviating morbidity and mortality of atherosclerotic cardiovascular diseases. However, novel drug targets like endoglin receptor, PPARα, squalene synthase, thyroid hormone analogues, scavenger receptor and thyroid hormone analogues are more powerful to control the process of atherosclerosis. Therefore, the review briefly focuses on different novel targets that act at the starting stage of the plaque form to the thrombus formation in the atherosclerosis.

    ABSTRACT: Blood lipids are cardiovascular health indicators. High LDL cholesterol values and/or high total cholesterol (TC)/HDL cholesterol ratios are positively related with cardiovascular mortality. Evidence suggests that a Mediterranean diet can reduce the incidence of cardiovascular diseases. Adherence to the Mediterranean diet is often measured by the Mediterranean Diet Score (MDS). However, the association between the Mediterranean diet and blood lipid profiles seems still inconclusive. The aim of this study was to investigate the relationship between the MDS, its different components and blood lipid profiles.

    ABSTRACT: Abstract Objective: It has been widely known that cardiovascular disease (CVD) risk is increased in menopause. The aim of the study was to evaluate whether this risk was elevated in young women with diminished ovarian reserve (DOR). Methods: A hundred women with DOR and 100 women with normal ovarian reserve (NOR) attending the infertility unit at Suleymaniye Maternity, Research &Training Hospital, were enrolled in the study. CVD risk markers such as insulin resistance (defined by the homeostasis model assessment ratio [HOMA-IR]), C-reactive protein (CRP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), and triglyceride (TG) were assessed. Results: HOMA-IR, CRP, TG, LDL levels were higher and HDL was lower among patients with DOR compared to the controls (p < 0.05 for all). There were positive associations between DOR and HOMA-IR, CRP, TG, LDL levels and a negative correlation with HDL (p < 0.05 for all). However, multivariate logistic regression analysis showed that HOMA-IR, CRP, TG, and HDL were independent variables that were associated with DOR. Conclusions: CVD risk markers were increased in women with DOR. Further studies with larger groups are needed to investigate the nature of the link in these patients.
