Abstract

OBJECT I V E S This study explored whether an individual or a cluster of risk factors affects the extent of necrotic core (NC) assessed by intravascular ultrasound (IVUS) radiofrequency data (RFD) analysis. BACKGROUND Several systemic diseases contribute to the development of coronary artery disease. METHODS The Global Intravascular Radiofrequency Data Analysis Registry was a prospective, multicenter, nonrandomized database that enrolled 990 patients with coronary artery disease in whom 1 major coronary artery was imaged by IVUS-RFD. For the multivariable analysis, the population was divided into 4 classes: young women, young men (both 62 years). Mean NC area was categorized as 1: top quartile (>= 0.62 mm(2)) or as 0: lower 3 quartiles. RESULTS Young patients had less NC compared with older patients (0.40 +/- 0.36 mm(2) of NC vs. 0.50 +/- 0.46 mm(2) in old patients, p = 0.0007). Nondiabetic patients had less NC than diabetic patients (0.43 +/- 0.41 mm(2) of NC vs. 0.51 +/- 0.44 mm(2) in diabetic patients, p = 0.02). The NC area was lower in normotensive patients (0.40 +/- 0.36 mm(2)) than in hypertensive patients (0.48 +/- 0.44 mm(2)) (p = 0.02). In the bivariate analysis, age, hypertension, diabetes, and prior coronary artery bypass graft were statistically significant, however in logistic regression analysis, only age (odds ratio [OR]: 1.023, 95% confidence interval [CI]: 1.009 to 1.037, p = 0.001) and diabetes (OR: 1.636, 95% CI: 1.174 to 2.279, p = 0.004) remained statistically significant. In a per-class logistic regression analyses including only diabetes as covariate, the OR in young women was 2.1 (95% CI: 0.77 to 6.0, p = 0.14), in young men the OR was 1.6 (95% CI: 0.90 to 2.7, p = 0.11), in old women the OR was 2.3 (95% CI: 1.09 to 4.9, p = 0.03), and in old men the OR was 1.6 (95% CI: 0.96 to 2.7, p = 0.07). Further, when only patients with diabetes and hypertension were included, young men (OR: 2.0, p = 0.041), old women (OR: 3.04, p = 0.046), and old men (OR: 2.2, p = 0.025) were significant. CONCLUSIONS Individually and collectively, age and diabetes mellitus are associated with an increase in NC by IVUS-RFD analysis.
