Abstract/OtherAbstract:
1. Coronary endothelial function and brachial-ankle pulse wave velocity (baPWV) are independent predictors of cardiovascular events. Thus, in the present study we examined the relationship between baPWV and endothelium-dependent and -independent coronary vasodilatory functions. 2. Sixty-five patients (12 diabetic and 53 non-diabetic) with no significant stenosis of the coronary artery were studied and baPWV determined. After cardiac catheterization, graded doses of bradykinin (BK; 0.2, 0.6 and 2.0 μg/min), nitroglycerin (NTG; 250 μg) and papaverine (Pa; 12 mg) were administered into the left anterior descending coronary artery. Coronary blood flow (CBF) was measured using a Doppler flow wire. 3. In the 65 patients, an inverse correlation was found between baPWV and the percentage change in epicardial coronary artery diameter (Δ%CoD), as well as the percentage change in CBF (Δ%CBF), following administration of BK (endothelium-dependent vasodilator). Moreover, inverse correlations were found between baPWV and Δ%CoD following administration of NTG (endothelium-independent vasodilator) and Δ%CBF following administration of Pa (endothelium-independent vasodilator). 4. Multivariate analysis revealed diabetes to be independently and significantly associated with baPWV, BK-induced Δ%CBF and Δ%CoD and Pa-induced Δ%CBF. 5. In conclusion, the results of the present study suggest that increased baPWV is associated with endothelium-dependent and -independent coronary vasodilatory dysfunction. Non-invasive and straightforward baPWV measurement may be useful for the assessment of coronary risk factors, particularly in diabetic patients.
