Tiny particles in polluted air can increase the risk of cardiovascular and pulmonary morbidity and mortality for people exercising outdoors, said Professor Patrick De Boever from the Centre for Environmental Sciences, Hasselt University, Hasselt, Belgium. However, on a population level, the positive effects of exercise offset the hazards of air pollution.

Carotid artery reactivity may help assess cardiovascular risk

8 days ago

Lower carotid artery reactivity (CAR%) correlates with older age and cardiovascular risk factors, whereas CAR% demonstrates positive association with coronary artery responses to the cold pressor test (CPT), a recent study has found.

Researchers used ultrasound to measure both resting and peak carotid artery diameters during the CPT, with CAR% being calculated as the relative change from baseline (%). CAR% was compared between young (n=50; 24 ±3 years) and older participants (n=44; 61 ±8 years); the relationships between CAR% and traditional cardiovascular risk factors in 50 participants (44 ±21 years) were also evaluated.

Using transthoracic Doppler echocardiography, a fundamental instrument to understand heart damage during essential arterial hypertension, researchers then compared the left anterior descending (LAD) artery velocity with carotid artery diameter (ie, CAR%) during the CPT (n=33; 37 ±17 years). [J Cardiovasc Med (Hagerstown) 2007;8:997-1006]

CAR% was significantly larger in young compared with older healthy participants (4.1 vs 1.8; p<0.001). Participants with no cardiovascular risk factors showed greater CAR% than those with at least two risk factors (2.9 vs 0.5; p=0.019).

During CPT, both the carotid artery diameter and LAD velocity increased (p<0.001). Carotid diameter (r=0.486; p<0.004) and change in velocity (r=0.402; p<0.02) were both associated with LAD velocity.

“Therefore, CAR% may represent a valuable technique to assess cardiovascular risk, while CAR% seems to reflect coronary artery vasodilator function,” according to researchers.

CAR%, which involves carotid artery diameter responses to a CPT, is a noninvasive measure of conduit artery function in humans, they added.
