Passive smoking is associated with early arterial damage, but the potential for reversibility of this damage is unknown.
To assess the reversibility of arterial endothelial dysfunction, a key marker of early atherosclerosis.
Academic medical center.
60 healthy persons 15 to 39 years of age: 20 with no exposure to active or passive smoking, 20 nonsmoking passive smokers (exposure to environmental tobacco smoke for ≥ 1 hour per day for ≥ 2 years), and 20 former passive smokers.
Arterial endothelial function measured by noninvasive ultrasonography.
Endothelium-dependent dilatation was significantly better in former passive smokers (5.1% ± 4.1% [range, −1.2% to 15.6%]) than in current passive smokers (2.3% ± 2.1% [range, −0.2% to 6.7%]) (P = 0.01), although both groups were significantly impaired compared with nonsmoking controls (8.9% ± 3.2% [range, 2.1% to 16.7%]) (P ≤ 0.01 for both comparisons).
In healthy young adults, arterial endothelial dysfunction related to passive smoking seems to be partially reversible.
