Association Between Hypertension and Coronary Artery Disease as Assessed by Coronary Computed Tomography

Multidetector row computed tomography (MDCT) enables the accurate noninvasive assessment of coronary artery stenosis and plaque imaging. The characteristics of patients who have coronary artery disease (CAD) as assessed by MDCT coronary computed tomography (CT) are not well known. Participants consisted of 513 consecutive patients with suspected CAD who underwent coronary CT. The authors quantified patient characteristics, including the prevalence of hypertension (HTN), hyperlipidemia and diabetes mellitus (DM), visceral fat area (VFA) and subcutaneous fat area using CT, and plasma levels of metabolic factors, including adiponectin and leptin. Although plasma levels of adiponectin in men and leptin in women were significantly associated with chronic kidney disease, there were no differences in these levels between patients with and without CAD. HTN was most significantly associated with the presence of CAD by multivariate logistic regression analysis (men, P=.002; women, P=.048). Finally, the percentage of CAD significantly increased as systolic blood pressure increased (trend, P=.0002) in men but not women. In conclusion, hypertension was significantly associated with CAD as assessed by coronary CT.
