Parameters of high-density lipoproteins in patients with arterial hypertension in combination with other components of metabolic syndrome

Abstract

Parameters of HDL (concentrations of cholesterol, apoprotein A1, and phospholipids and phospholipid composition) determining their functional properties were studied in patients with arterial hypertension in combination with other components of metabolic syndrome (abdominal obesity, hyperlipidemia, and impaired glucose tolerance). Patients with isolated arterial hypertension did not differ from the control group by the concentration of apoprotein A1 and HDL cholesterol, but had lower content of HDL phospholipids and changed phospholipid composition: lower ratio of phosphatidylcholine and higher relative contents of lysophosphatidylcholine, sphingomyelin, and phosphatidylethanolamine. Parameters of HDL in patients with arterial hypertension associated with other components of metabolic syndrome did not differ from those in patients with isolated arterial hypertension. The observed changes in HDL in patients with arterial hypertension alone or in combination with other components of metabolic syndrome can impair functional capacity of HDL in reverse cholesterol transport, which increases the risk of atherosclerosis.
