[The secretory phospholipase A2 and transport of lipids by lipoproteins in patients with the risk of cardio-vascular pathology (the system "score") of lower and average degree. The diagnostic significance of the test].

The clinical and pathomorphologic data demonstrate that the most frequent cause of cardiac infarction is the formation of "soft" atheromatosis plaques in the intima of arteries. Their rupture results in thrombosis of coronary arteries. The plaques are characterized by higher content of triglycerides. On the basis of the research data, it is possible to validly consider that the detection of secretary phospholipase content A2 conjugated with lipoproteins is the test of systemic inflammatory response. This response is formed under atherosclerosis in vivo as a feedback to the accumulation in the intercellular medium of the endogenic flogogens (initiators of biological reaction of inflammation)--lipoproteins of lower density subclass A. Their utilization in the intima, as a pool of local interstitial tissue, by the resident macrophagocytes transformed from monocytes result in the formation of doth soft and disposed to laceration atheromatosis plaques and the atherothrombosis of coronary arteries and rarer of carotids. Concurrently, the increase of lipoproteins content in blood plasma is supposed to be the test of proliferation of cells in vivo, the smooth muscle cells of medium in particular. The simultaneous detection of content of secretory associated with lipoproteins phospholipase A2 and lipoprotein (a) can be considered as a valid risk factor of atherosclerosis and atherothrombosis--atheromatosis of intima of arteries with the formation of "soft" plaques in the intima, their laceration and thrombosis of coronary arteries and clinical presentation of cardiac infarction. The diagnostic triad of formation of soft plaques in the intima can be composed of the higher level of triglycerides, the content of protein of phospholipase A2 and lipoprotein (a).
