Systemic factors and blood flow velocity related to atherosclerosis have been examined mainly separately or by in vitro studies. The aim of our study was to investigate the association between local coronary blood flow (corrected TIMI frame count, CTFC) and systemic atherosclerosis-related inflammatory parameters such as soluble intercellular adhesion molecule-1 (sICAM-1), interleukin-6 (Il-6), high sensitivity C-reactive protein (hsCRP) and von Willebrand factor (vWF) in humans. We enrolled the following groups of ischemic heart disease (IHD) patients: patients with coronary stenosis and stable (CAD, n = 96) or unstable angina (ACS, n = 27), patients with documented myocardial ischemia and normal coronary angiogram (NEG, n = 68). Patient groups showed only marginal differences in CTFC or sICAM-1 levels. In contrast, when IHD patients were studied individually, general positive correlation was found between CTFC and sICAM-1 level (r = 0.33; in NEG r = 0.25; in CAD r = 0.37; in ACS r = 0.61), being the strongest in ACS. The relation was independent from age, gender, BMI, smoking, hypertension, diabetes, previous myocardial infarction, family history of IHD, medication, hsCRP, IL-6 and vWF levels. (odds ratio, OR = 6.4; CI 95%: 2.43-16.84; p < 0.05). Nevertheless, correlation between CTFC and IL-6, hsCRP, vWF levels was not found. These results indicate inverse correlation between coronary blood flow and adhesion molecule production independently from conventional cardiovascular risk factors and inflammatory markers.

In recent years new biomarkers able to measure the coronary atherosclerotic burden have been investigated. The aim of the present study was: i) to measure plasma levels of four biomarkers: C reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1), interleukin 6 (IL-6), 8-isosprostane (8-ISO), in a series of patients undergoing coronary angiography; ii) to assess the power of the biomarkers to predict critical coronary stenosis detected by angiography. The study population consisted of a group of 438 subjects undergoing coronary angiography; 160 patients with 0, 1, 2, or 3 critical vessels were selected, and biomarkers plasma levels were measured in plasma samples obtained before the procedure. The most predictive biomarker was then assayed in 120 patients with critical stenosis and 120 unmatched patients without stenosis. CRP, sICAM-1, IL-6 and 8-ISO plasma levels increased with the number of diseased vessels. All biomarkers were good predictors of critical stenosis (receiver-operator-curve [ROC] areas; CRP = 0.880, IL-6 = 0.936, sICAM-1 = 0.907, 8-ISO = 0.873). IL-6 was confirmed in an expanded sample of 240 subjects to be the best predictor with a ROC area = 0.959. With a threshold of 3.6 ng/l, a 100% sensitivity (120/120) and a 90% specificity (108/120) was observed. In conclusion, IL-6, sICAM-1, CRP and 8-ISO are predictive of CAD. IL-6 predicts critical coronary stenosis with the highest sensitivity and specificity.

The objective of this study was to evaluate the expression of cell adhesion molecule (CAM) receptors (integrins) on monocyte subsets in heart failure (HF) and examine their prognostic implication.Increased levels of soluble CAMs have been observed in patients with HF, but the precise mechanism of monocyte adhesion to the vascular endothelium remains unknown. Patients with acute HF (AHF, n=51) were compared to those with stable HF (SHF, n=42) and stable coronary artery disease (CAD, n=44) without HF. Expression of integrins-receptors to intercellular adhesion molecule-1 (ICAM-1R) and vascular CAM-1 (VCAM-1R) on monocyte subsets was assessed by flow cytometry. Monocyte subsets were defined as CD14++CD16-CCR2+ ('classical', Mon1), CD14++CD16+CCR2+ ('intermediate', Mon2), and CD14+CD16++CCR2- ('non-classical', Mon3). Compared to patients with SHF, those with AHF had significantly higher expression of ICAM-1R on Mon2 (p=0.01). Compared to those with stable CAD, patients with SHF had a significantly higher expression of ICAM-1R on Mon2 (p=0.025).Compared to SHF, patients with AHF had a similar expression of VCAM-1R on both Mon1 and Mon3 but significantly higher expression on Mon2 (p=0.019). There were no significant differences between SHF and CAD in monocyte expression of VCAM-1R. In multivariate Cox regression analysis, VCAM-1R expression on Mon2 was associated with adverse clinical outcome (death or rehospitalisation) in AHF [HR 1.07 (1.01-1.14), p=0.029]. In conclusion, HF is associated with increased monocyte expression of integrins-receptors to both ICAM-1 and VCAM-1, being particularly linked to Mon2 subset. Expression of VCAM-1R on Mon2 may have prognostic value in patients with AHF.
