Serum lipids and regulation of tissue factor-induced coagulation in middle-aged men

Thrombosis Research

Abstract

Formation of an occlusive thrombus by exposure of tissue factor (TF) to circulating blood and subsequent triggering of coagulation by TF-activated factor VII (FVIIa) complexes on ruptured atherosclerotic plaques is thought to be a key event in myocardial infarction. Tissue factor pathway inhibitor (TFPI) is a potent inhibitor of TF-induced coagulation in which the anticoagulant function most probably is restricted to free TFPI in human plasma. The present study was undertaken to assess the interrelations between serum lipids and components of TF-induced coagulation in 234 apparently healthy men aged 36-56 years recruited from the general population. Plasma free TFPI antigen (Ag) was positively correlated (P < .001) with total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, apolipoprotein B (apoB-100), fibrinogen, total amount of FVII (FVIIam), coagulation activity of factor VII (FVIIc), and FVIIa. The significant predictors for free TFPI Ag were total cholesterol, triglycerides, fibrinogen, FVIIc, and age, which explained 33% of the plasma variation in free TFPI Ag assessed by multiple regression analysis. A highly significant (P < .0001) linear trend for increase in atherogenic lipids (i.e., total choles...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

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.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
