Correlation between plasma angiopoietin-1, angiopoietin-2 and matrix metalloproteinase-2 in coronary heart disease

Correlation between plasma angiopoietin-1, angiopoietin-2 and matrix metalloproteinase-2 in coronary heart disease

Angiopoietin-2 (Ang-2) plays a critical role in inducing tumor cell infiltration, and this invasive phenotype is caused by up-regulation of matrix metalloproteinase (MMP)-2. The relationship between Ang-2 and MMP-2 in atherosclerosis has not been reported yet. The aim is to measure the plasma concen...

description Angiopoietin-2 (Ang-2) plays a critical role in inducing tumor cell infiltration, and this invasive phenotype is caused by up-regulation of matrix metalloproteinase (MMP)-2. The relationship between Ang-2 and MMP-2 in atherosclerosis has not been reported yet. The aim is to measure the plasma concentrations of Ang-1, Ang-2 and MMP-2 and assess the correlation between the concentrations of these factors in coronary heart disease (CHD) patients. The testing was done in a cross-sectional study. We prospectively enrolled 42 individuals with acute myocardial infarction, 42 individuals with unstable angina pectoris, 42 individuals with stable angina pectoris and 45 healthy control subjects. Concentrations of Ang-1, Ang-2 and MMP-2 were measured using the enzyme-linked immunosorbent assay (ELISA) method. Spearman's rank correlation was calculated to evaluate the relationships between MMP-2 and Ang-1, and MMP-2 and Ang-2 in patients with CHD. Patients with acute myocardial infarction and unstable angina pectoris had higher Ang-2 and MMP-2 levels compared with stable angina patients and healthy control subjects ( < 0.05), while concentrations of Ang-1 were not statistically different between the groups. Spearman's rank correlation showed that Ang-2 levels positively correlated with MMP-2 in patients with CHD ( = 0.679, < 0.001). Plasma Ang-2 and MMP-2 levels but not Ang-1 levels were increased in patients with CHD. Ang-1 correlated weakly with MMP-2, whereas the Ang-2 and MMP-2 correlation was strong in patients with CHD. Ang-2 may play a role in atherosclerosis, and have an interaction with MMP-2.
