Lipid peroxides and atherosclerosis
Abstract
Plasma lipid peroxide concentrations were measured in 100 patients with occlusive arterial disease proved angiographically (50 patients with ischaemic heart disease, 50 with peripheral arterial disease) and compared with values in 75 control patients with no clinical evidence of atherosclerosis. Lipid peroxide concentrations were significantly higher in patients both with ischaemic heart disease (median 4.37 mumol/l (interquartile range 3.85-5.75 mumol/l); p less than 0.001) and with peripheral arterial disease (median 4.37 mumol/l (3.88-5.21 mumol/l); p less than 0.001) than in controls (median 3.65 mumol/l (interquartile range 3.29-3.89 mumol/l). Overall there was a significant but weak correlation between plasma lipid peroxide and plasma triglyceride concentrations (rs = 0.25; p less than 0.001) but not between plasma lipid peroxide and plasma total cholesterol concentrations. Furthermore, hypertension, obesity, diabetes, smoking, positive family history, and intake of beta blockers and thiazide diuretics were not associated with significant differences in lipid peroxide values. This study provides clinical support to experimental data indicating that peroxidised lipids may be important in atherogenesis and its complications...Continue Reading

Cardiovascular Diseases: Risk Factors
Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
Atherosclerosis Disease Progression
Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
Antihypertensive Agents: Mechanisms of Action
Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
