  Figure 1. Flowchart of patient enrolment. CAG = coronary angiography; TyG = triglyceride–glucose; Hs-CRP = high-sensitivity C-reactive protein.

  Figure 2. Pearson correlation between variables and adverse outcomes. Within the plot, the triangular portion highlights the correlations between variables. Dark blue squares denote positive correlations, and orange squares denote negative correlations. The size of each square corresponds to the absolute value of Pearson’s correlation coefficient. The higher-right section depicts the correlation between variables and adverse outcomes. Purple indicates significant correlation (p < 0.05), gray indicates non-significant correlation (p ≥ 0.05), thicker lines indicate larger absolute values of the correlation coefficient, solid lines indicate positive correlation, dashed lines indicate negative correlation. Significance levels are denoted as follows: * p < 0.05, ** p < 0.01, *** p < 0.001. TC = total cholesterol; EF = ejection Fraction; Cr = serum creatinine; FPG = fasting plasma glucose; CTI = C-reactive protein–triglyceride–glucose index; Hs-CRP = high-sensitivity C-reactive protein; LDL-C = low-density lipoprotein–cholesterol; ALB = albumin; TyG = triglyceride–glucose; and BMI = body mass index.

  Figure 3. RSC showing the connection between the CTI and adverse outcomes. (A) MACEs; (B) cardiac death; (C) all-cause death; (D) myocardial infarction. CTI = C-reactive protein–triglyceride–glucose index; MACEs = major adverse cardiac events. The pink shaded area represents the 95% confidence interval. The pink solid line shows the trend of the estimated hazard ratio (HR) with changes in CTI. The black dashed line indicates the horizontal reference line HR = 1.

  Figure 5. Subgroup analyses of the associations of the CTI with myocardial infarction across the subgroups of covariates, dichotomously or medially. CTI = C-reactive protein–triglyceride–glucose index; BMI = body mass index; TG = triglyceride; TC = total cholesterol; LDL-C = low-density lipoprotein–cholesterol; HDL-C = high-density lipoprotein–cholesterol; and MACEs = major adverse cardiac events.
