Impact of smoking on coronary atherosclerosis and remodeling as determined by intravascular ultrasonic imaging.

Using preintervention intravascular ultrasound among patients with coronary artery disease, the current study indicates that patients who smoked had a similar degree of reference and lesion site arterial area, plaque burden, lumen compromise, attenuated adaptive vascular remodeling response, and less lesion site calcification as nonsmokers.
