Association between smoking status and subclinical coronary atherosclerosis in asymptomatic Korean individuals.

ABSTRACT:

Objectives

In this study, we sought to evaluate the association between smoking status and subclinical coronary atherosclerosis, as detected by coronary computed tomography angiography (CCTA), in asymptomatic individuals.

Methods

We retrospectively analyzed 9,285 asymptomatic participants (mean age, 53.7±8.0 years; n=6,017, 64.8% male) with no history of coronary artery disease (CAD) who had undergone self-referred CCTA. Of these participants, 4,333 (46.7%) were considered never smokers, 2,885 (31.1%) former smokers, and 2,067 (22.3%) current smokers. We assessed the degree and characteristics of subclinical coronary atherosclerosis using CCTA, with obstructive CAD defined as a diameter stenosis of at least 50%.

Results

Compared with never-smokers, former smokers exhi
