Hämeenlinna Metabolic Syndrome Research Program: Oxidized LDL and Arterial Elasticity in Metabolic Syndrome and Controls (HMS-01)

2014-07-23 21:09:22 | BioPortfolio

Summary

Mechanisms that link metabolic syndrome to atherosclerosis are incompletely understood. As a part of Hämeenlinna Metabolic Syndrome Research Program (HMS), 40 men with metabolic syndrome and their 40 physically active controls (age: 30 to 65 years) are compared in a cross-sectional study. Except routine laboratory parameters, arterial elasticity and levels of oxidized LDL are determined.

Study hypothesis: Levels of oxidized LDL and findings in arterial elasticity may differ between subjects with metabolic syndrome and controls explaining the elevated risk for cardiovascular diseases among patients with metabolic syndrome.

Description

Accumulation of oxidized low-density lipoproteins in the intimae of arteries together with risk factors known to enhance atherosclerosis, damage the endothelium of the arterial wall. Dysfunction of the endothelium leads into loss of elasticity of the artery. Especially a reduction in the elasticity of small arteries has been found prominent in atherosclerosis and is believed to serve as a marker for early stages of atherosclerosis.

In this study, we investigate whether the levels of oxidized LDL and arterial elasticity differ between patients with metabolic syndrome and their physically active controls. Oxidized LDL is assessed by a two-site ELISA immunoassay (Mercodia, Uppsala, Sweden). The capacitive elasticity of large arteries (C1) and the reflective elasticity of small arteries (C2) are automatically assessed by the CR-2000 as a mean of five most similar pulse waves appearing during the measurement. C1 identifies the elastic properties of aorta and other large arteries, C2 the endothelial function of the microvascular circulation. Proper statistical methods are used to reveal possible differences and their significance between the patients and controls.

Medical and Biotech [MESH] Definitions

A cluster of metabolic risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome X include excess ABDOMINAL FAT; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state. (from AHA/NHLBI/ADA Conference Proceedings, Circulation 2004; 109:551-556)

A cluster of symptoms that are risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome include ABDOMINAL OBESITY; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state.

ANGINA PECTORIS or angina-like chest pain with a normal coronary arteriogram and positive EXERCISE TEST. The cause of the syndrome is unknown. While its recognition is of clinical importance, its prognosis is excellent. (Braunwald, Heart Disease, 4th ed, p1346; Jablonski Dictionary of Syndromes & Eponymic Diseases, 2d ed). It is different from METABOLIC SYNDROME X, a syndrome characterized by INSULIN RESISTANCE and HYPERINSULINEMIA, that has increased risk for cardiovascular disease.

A condition of metabolic imbalance that is caused by complications of initially feeding a severely malnourished patient too aggressively. Usually occurring within the first 5 days of refeeding, this syndrome is characterized by WATER-ELECTROLYTE IMBALANCE; GLUCOSE INTOLERANCE; CARDIAC ARRHYTHMIAS; and DIARRHEA.

Acquired or inborn metabolic diseases that produce brain dysfunction or damage. These include primary (i.e., disorders intrinsic to the brain) and secondary (i.e., extracranial) metabolic conditions that adversely affect cerebral function.
