Smoking and Coronary Atherosclerosis: Disproportionate Impact on the Right Coronary Artery.

ABSTRACT:

We aimed to study the long-term effect of smoking on coronary atherosclerosis progression at the segmental level.

Methods

Angiographic data (1989-2017) on current, former, and nonsmokers were collected from the Swedish Coronary Angiography and Angioplasty Registry.
