Experts suggest analyzing lipoproteins INC 'protective' to improve diagnosi

newindicatorscrdiovascularMEXICO CITY (20/OCT/2012.) - Researchers at the National Institute of Cardiology "Ignacio Chavez" (INC), determined that the "protective" for cardiovascular risks of high density lipoprotein (HDL by its acronym in English) , is related to its structure and composition.

High density lipoproteins are composed of cholesterol, phospholipids, and triglycerides, and its main function is to transport fats through the blood to the liver, where they are processed and eliminated.

In the words of Dr. Oscar Perez Mendez, head of the project, high-density lipoprotein may be protective according to their size and the amount of lipids (fats) they contain.

The study was conducted in Mexican patients divided into three categories: no coronary calcium (equivalent to absence of a lesion in the coronary arteries), with limited reservoir of calcium and high calcium in coronary arteries to measure the amount of high density lipoprotein, and determine the structure.

The results found that patients with high coronary calcium, are those with increased risk of atherosclerosis and cardiovascular problems. This is because low levels of high density lipoproteins, as these are identified structure larger and less phospholipids and cholesterol.

In patients without coronary events levels of high density lipoproteins were normal and their size was smaller.

The specialist of the National Cardiology Institute said the study suggests studying the different components of high density lipoproteins to reach a better cardiovascular risk assessment.

INC Research also led HDL phospholipids used as markers to identify the presence of kidney damage, in this case the experts at this institution are in the process of evaluating these results.
