Abstract

Background: Circulating endothelial cells (CEC) may be used to find new strategies for the early di­agnosis of cardiovascular diseases. The major objective of the project is to broaden knowledge of CEC biology by determining their phenotypic characteristics. The additional aim is to clarify whether on the basis of these information it is possible to identify the origin of CEC release (from various cardiovascular compartments).

Methods: Circulating endothelial cells were collected from arterial blood prior to angiography, as well as from arterial and venous blood obtained after angiography/coronary angioplasty, from 18 patients with non-ST-segment elevation myocardial infarction (NSTEMI). CECs were quantified by flow cytometry and defined as Syto16 (dye)+, CD45dim/neg, CD31+ and CD146+. The additional CD36+ was establish as a marker of endothelial cells released from small vessels of the microcirculation.

Results: The total number of CECs increased significantly after the percutaneous transluminal coronary angioplasty (PTCA) in the arterial system. Number of CECs isolated at similar time points (after invasive procedure) did not differ significantly between arteries and veins, but the number of CD36+ CECs after coronary angioplasty was significantly higher in the venous system, than in the arterial system.

Conclusions: The number of CD36+ in artery samples obtained after coronary angioplasty (PTCA) had tendency to be decreased (in comparison to the sample obtained before angiography). It was major difference between those who had PTCA performed vs. those who had not.
