Insights
Inflammation markers, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), are elevated in patients with coronary artery ectasia (CAE). These findings suggest a role for vascular inflammation in the development of CAE.
Area of Science:
- Cardiology
- Vascular Biology
- Inflammation Research
Background:
- Coronary artery ectasia (CAE) involves abnormal coronary artery dilation.
- The role of inflammation in CAE pathogenesis is not well understood.
- Soluble adhesion molecules, ICAM-1 and VCAM-1, are key inflammatory markers.
Purpose of the Study:
- To investigate plasma levels of ICAM-1 and VCAM-1 in patients with CAE.
- To determine the association between these adhesion molecules and CAE, with or without obstructive coronary artery disease (OCAD).
Main Methods:
- Study included 67 participants across four groups: normal coronary artery (NCA), isolated CAE, OCAD, and combined OCAD with CAE.
- Plasma levels of ICAM-1 and VCAM-1 were measured.
- Statistical analyses, including multivariate logistic regression, were performed.
Main Results:
- ICAM-1 and VCAM-1 levels were significantly higher in patients with isolated CAE compared to NCA.
- Patients with CAE (with or without OCAD) showed elevated ICAM-1 and VCAM-1 compared to OCAD-only patients.
- A positive correlation was found between CAE presence and ICAM-1/VCAM-1 levels.
Conclusions:
- Elevated plasma ICAM-1 and VCAM-1 are observed in patients with CAE.
- These findings indicate that heightened vascular wall inflammation may contribute to CAE development.
- Adhesion molecules could serve as potential biomarkers for CAE.
Background:
Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation of the coronary arteries. There are scarce data about the role of inflammation in CAE. In the present study, the plasma soluble adhesion molecules intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) levels in CAE were investigated.
Methods:
The study population (n = 67) consisted of four groups. Group 1: patients with normal coronary artery (NCA); group 2: patients with isolated ectasia without stenotic lesion; group 3: patients with obstructive coronary artery disease (OCAD) without CAE; group 4: patients with both OCAD and CAE.
Results:
Plasma concentrations of ICAM-1 and VCAM-1 were higher in patients with isolated ectasia than in cases with NCA (p < 0.001 and p < 0.001, respectively). Compared with OCAD patients, patients with CAE had significantly elevated concentrations of ICAM-1 and VCAM-1 (p < 0.001 and p < 0.05, respectively). The levels of ICAM-1 and VCAM-1 of the CAE and OCAD group were higher than in patients in the OCAD group (p < 0.05 and p < 0.05, respectively). We detected a positive correlation between the presence of CAE and the levels of ICAM-1 and VCAM-1. Multivariate logistic regression analyses revealed a significant independent relation between the presence of CAE and ICAM-1 and VCAM-1.
Conclusion:
We found elevated plasma levels of ICAM-1 and VCAM-1 in patients with CAE and OCAD + CAE compared with subjects with NCA and OCAD. These data strongly suggest that more severe vascular wall inflammation may play a role in the pathogenesis of CAE.
