Sleep duration, PSQI, history ofdiabetes, LDL-C, and CRP were identified as independent predictors of TCFA inpatients with stable angina [Sleep duration: OR = 0.764, 95% CI (0.625–0.932);PSQI: OR = 1.233, 95% CI (1.108–1.372); diabetes: OR = 2.081, 95% CI(1.078–4.015); LDL-C: OR = 2.222, 95% CI (1.109–4.453); CRP: OR = 1.543, 95%CI (1.097–2.172)]. Here, CRP is linked to diabetes mellitus.
