BACKGROUND: Coronary artery calcification (CAC) is highly prevalent among dialysis patients and is associated with increased cardiovascular and all cause mortality. Magnesium (Mg) inhibits vascular calcification in animal and in-vitro studies but whether the same effect occurs in humans is uncertain. METHODS: A single centre cross-sectional study of 80 prevalent peritoneal dialysis (PD) patients; on PD only for a minimum of 3 months. A radiologist blinded to patient status calculated their abdominal aortic calcification (AAC) scores on lateral lumbar spine radiographs, a validated surrogate for CAC...

BACKGROUND AND AIMS: Elevated levels of lipoprotein(a) [Lp(a)] and oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB) predict the progression of pre-existing mild-to-moderate calcific aortic valve stenosis (CAVS). Whether indirect markers of oxidation-specific epitopes (OSE) are also predictive is not known. The association between IgG and IgM autoantibodies and malondialdehyde-modified low density lipoprotein (MDA-LDL) and IgG and IgM apolipoprotein B immune complexes (apoB-IC), and the hemodynamic progression rate of CAVS was determined in the ASTRONOMER (Aortic Stenosis Progression Observation: Measuring Effects of Rosuvastatin, NCT00800800) trial...

OBJECTIVES: In ankylosing spondylitis (AS) patients, cardiac and vascular involvement may manifest as atherosclerosis and coronary artery disease. Systemic inflammation, oxidative stress, increased low-density lipoprotein (LDL) cholesterol and decreased high-density lipoprotein (HDL) cholesterol constitute a significant risk for atherosclerosis. This study investigated the relationship between carotid intima-media thickness (CIMT), LDL/HDL ratio, total oxidant status (TOS; an indicator of oxidative stress) and ischemic modified albumin (IMA; an ischemic marker in AS patients)...

BACKGROUND: Rheumatoid arthritis is associated with a 50% increased risk in cardiovascular mortality. Inflammation is thought to accelerate atherosclerosis and might also lead to an inflammatory rupture-prone plaque phenotype. We tested the hypothesis that patients with active rheumatoid arthritis also have carotid plaque inflammation and that plaque inflammation correlates with clinical and serological markers of inflammation. METHODS: Patients with active rheumatoid arthritis, defined as the Disease Activity Score in 28 joints (DAS28) score of more than 3·2, were recruited to a single centre study in the UK...

Cerebrovascular accident or stroke is defined by an abrupt onset of neurological deficit that is attributable to a focal vascular cause. Stroke is a major cause of morbidity and mortality worldwide. This may result from brain infarction or hemorrhage. Carotid atherosclerosis is a reasonable risk factor for cerebral ischemic stroke. Deranged lipid metabolism due to various modifiable and non-modifiable risk factors leads to the pathogenesis of atherosclerosis. This study is intended to find out any association between altered lipid metabolism (Cholesterol, Triglycerides, LDL : HDL ratio) and development of cerebral ischemia...

INTRODUCTION: Our prior publication suggested that elevated serum concentrations of low-density lipoprotein (LDL) was protective against the development of acute mountain sickness (AMS) while an inflammatory response was contributory to its development. The use of 3-hydroxy-3-methylglutaryl-coenzyme-A-reductase inhibitors ("statins") may be of interest to those traveling to altitude-these medications will lower serum LDL concentrations, but are also reported to have anti-inflammatory properties...
