Structural-and-functional alterations in the arterial wall and clinical manifestations of nonspecific aortoarteritis.
The authors studied structural-and-functional properties of the arterial wall, also assessing elastic properties of the common femoral artery and the brachial artery flow-dependent dilatation (FDD) index in a total of thirty-six patients presenting with nonspecific aortoarteritis (NAA). The overwhelming majority of the patients, i. e., twenty-four (89%), showed a statistically significant decrease in the FDD as compared with the control-group patients (P<0.05). We revealed a statistically reliable (P=0.0005) inverse correlation between the level of systolic arterial pressure and an increase in the rigidity index of the common femoral artery wall. Also determined was a correlation of the femoral artery wall rigidity (systolic AP equalling 140 mm Hg and higher) and the brachial artery flow-dependent dilatation index (r=-0.61). All the patients suffering from non-specific aortoarteritis were diagnosed as having a decrease in the elasticity values, accompanied by an increase in systolic arterial pressure (r=0.36; P=0.07). Comparing the level of systolic arterial pressure with the values of the distensibility coefficient and compliance coefficient revealed a weak inverse correlation (r=-0.28 and 0.21, respectively). Evaluating the impact of duration of the disease on the distensibility coefficient, compliance coefficient and the rigidity index made it possible to detect a statistically significant (P=0.0039) direct correlation between the rigidity index and the duration of non-specific aortoarteritis. To a leaser degree, the duration of the inflammatory process influenced the distensibility coefficient and compliance coefficient (r=-0.28; r=-0.30, respectively; P=0.06).
