Abstract

To investigate the changes of inflammatory factors and hemostatic variable in plasma after a high-fat meal in normocholesterolemic patients with essential hypertension. A total of 60 hypertensive patients were randomly assigned to accept a single high-fat meal (group 1, n=40) or not (group 2, n=20) in the morning after an overnight fast, and 20 healthy participants (group 3) consumed a single high-fat meal on the same day. Plasma lipid profiles, high-sensitivity C-reactive protein (hsCRP), tumor necrosis factor alpha (TNFalpha), soluble P-selectin and plasminogen activator inhibitor type 1 (PAI-1) antigen levels were measured at fasting and 4 h after meal ingestion. Postprandial triglyceride levels increased significantly in groups 1 and 3 (P<0.01), whereas levels were higher in group 1 (P<0.001). Postprandial plasma TNFalpha, hsCRP, soluble P-selectin and PAI-1 antigen levels increased in group 1 (P<0.001) but not in group 3. Postprandial plasma triglyceride level was correlated with log(hsCRP) (P<0.001), TNFalpha (P<0.001), soluble P-selectin (P<0.01) and PAI-1 antigen (P<0.05) levels, respectively. Both postprandial plasma level of soluble P-selectin and that of PAI-1 antigen were positively and significantly correlated with...Continue Reading
