OBJECTIVES Significantly increased risk for developing cardiovascular disease in post-menopausal women is linked with the fall of oestrogen. Although supraphysiological levels of oestrogen may inhibit oxygen free radical mediated low-density lipoprotein (LDL) oxidation, the effect of physiological level of oestrogen on LDL oxidation is unknown. METHODS(More)
Lipoprotein(a) [Lp(a)], which combines structural elements of the lipid and fibrinolytic systems, is a major independent risk factor for the development of coronary heart disease. Eighty-four consecutive patients with peripheral vascular disease (of whom 42 had concomitant ischaemic heart disease) and 43 healthy controls were enrolled in a case-control(More)
BACKGROUND The purpose of the study was to investigate the relation of lipoprotein(a) and serum lipid parameters to restenosis after percutaneous transluminal coronary angioplasty (PTCA) and to assess the association of these same biochemical markers to coronary artery disease (CAD) in individuals with angiographically defined normal and diseased coronary(More)
AIMS Vitamin C (ascorbic acid) is a powerful antioxidant but there is limited information on its ability to prevent LDL oxidation and its interaction with other natural antioxidants in vivo. We assessed the effect of 4 weeks pharmacological supplementation with vitamin C 1 g day(-1) on copper induced LDL oxidation and lipid peroxidation. METHODS Blood(More)
OBJECTIVE To assess changes in lipid-lipoprotein profile in postmenopausal women taking tibolone and estrogen-progestin, compared with untreated controls. METHODS Sixty-three women were randomized to take a combined estrogen-progestin preparation (n = 31) or tibolone (n = 32), and 50 other women acted as controls. Fasting lipid-lipoprotein levels were(More)
Psoriasis is a common condition in the western world, but is uncommon in populations with a low prevalence of atherosclerosis such as Japanese, Blacks and indigenous North Americans. Psoriasis appeared to be more prevalent amongst patients attending our lipid clinic compared to the general population. Lipoprotein (a) (Lp(a)) is elevated in conditions such(More)
AIMS The use of oestrogen containing hormone replacement therapy (HRT) is related to a significantly reduced atherosclerotic cardiovascular risk in postmenopausal women. Oestrogen is thought to be antioxidant and may inhibit low-density lipoprotein (LDL) oxidation in vitro. We investigated the effect of combined oestrogen and progestogen HRT on LDL(More)
OBJECTIVES To compare lipoprotein(a) [Lp(a)] and albumin concentrations in patients with chronic renal disease receiving different forms of treatment and to determine, if any, the relationship between these variables. DESIGN A prospective cross-sectional, case-controlled study. SETTING A tertiary referral nephrology and dialysis unit. SUBJECTS(More)
BACKGROUND Vitamin E supplementation is associated with a reduced risk of developing atherosclerotic events; probably because it inhibits low-density lipoprotein (LDL) oxidation, an initial step in atherosclerosis. Metal ion-dependent LDL oxidation is a commonly used method to estimate oxidizability of LDL, but the effect of antioxidant supplementation on(More)
