[Arterial stiffness in patients with chronic obstructive pulmonary disease].
OBJECTIVE
To estimate arterial stiffness (AS) in patients with chronic obstructive pulmonary disease (COPD).


METHODS
A total of 112 COPD patients over 40 years of age entered a population-based trial. The patients with coronary heart diseases, peripheral vascular atherosclerosis, other severe chronic diseases in exacerbation were withdrawn. The control group consisted of 26 healthy volunteers matched by gender and age. AS was measured at arteriograph "Tensioclinic" ("Tensiomed", Hungary).


RESULTS
COPD patients, first of all elderly ones, had abnormal properties of arterial wall. Increased arterial rigidity and pulse wave reflection (accelerated pulse wave velocity and high index of augmentation) are strongly associated with elevation of central arterial pressure.


CONCLUSIONS
High arterial wall stiffness in COPD patients suggests an increased risk of cardiovascular diseases that necessitates examination in prospective studies.
