Logistic analysis showed that body mass index (BMI) ≥ 24.0 kg/m2 (24.0 kg/m2 vs. 18.5–23.9 kg/m2, odds ratio (OR): 1.361, 95% confidence interval (CI): 1.112–1.666, p = 0.003), advanced age (≥ 65/<65, OR:1.303, 95% CI: 1.060–1.602, p = 0.012), history of smoking (OR: 1.830, 95% CI: 1.379–2.428, p < 0.001), diabetes mellitus (OR: 1.380, 95% CI: 1.119–1.702, p = 0.003), hyperlipidemia (OR: 1.773, 95% CI: 1.392–2.258, p < 0.001), and APOE ɛ3/ɛ4 genotype (ɛ3/ɛ4 vs. ɛ3/ɛ3, OR: 1.514, 95% CI: 1.133–2.024, p = 0.005) were associated with coronary atherosclerosis in hypertensive patients. The gene discussed is APOE; the disease is hyperlipidemia.
