Abstract

ABSTRACT Background In the USA, heart disease is the leading cause of death for women and men. Coronary artery disease (CAD) is the most common type of heart disease. Purpose To investigate the association between behavioral and non-behavioral risk factors associated with subclinical atherosclerosis. Methods Patients referred for a CT angiography completed a demographic/behavioral questionnaire and medical history interview for CAD risk factors. Risk factor data were correlated with CAD subclinical atherosclerosis scores for 521 participants. Results Frequency among four levels of CAD revealed: no disease 38%, mild atherosclerotic 20%, moderate atherosclerotic 30%, and severe atherosclerosis 12%. Significant (p ≤ .05) demographic variables were as follows: age, race, marital status, and employment status. Significant predictive behavioral variables were as follows: tobacco use, daily water intake, sodium consumption, exercise days per week, and junk food consumption. Risk factors significantly associated with subclinical CAD included hypertension, diabetes, sleep apnea, and abnormal coronary calcium score. Discussion Multi-slice CT angiography allows early reliable evaluation of subclinical atherosclerosis and correlation with behavioral/non-behavioral risk factors with level of CAD, instrumental to primary and secondary CAD prevention, limiting tertiary CAD treatment. Translation to Health Education Practice Study results have implications for Health Educators with regard to intervention research planning, implementation, and evaluation.
