Triglyceride-glucose index is associated with poor prognosis in acute coronary syndrome patients with prior coronary artery bypass grafting undergoing percutaneous coronary intervention

Table 4 Predictive value of TyG index for MACCE in different Cox proportional hazards models

	TyG index as a continuous variable^a			TyG index as a categorical variable^b
	HR	95% CI	p value	HR	95% CI	p value
Crude model	1.28	1.09–1.51	0.003	1.45	1.17–1.79	< 0.001
Model 1	1.21	1.02–1.45	0.034	1.35	1.08–1.69	0.008
Model 2	1.42	1.10–1.83	0.008	1.49	1.14–1.94	0.004
Model 3	1.42	1.09–1.83	0.008	1.49	1.14–1.95	0.003
Model 4	1.42	1.09–1.86	0.009	1.53	1.16–2.01	0.003

Model 1: adjusted for age, male, BMI, SBP, current smoking, family history of CAD, hypertension, dyslipidemia, T2DM, prior MI, prior PCI, prior stroke, PAD, HF and CKD
Model 2: adjusted for variables in Model 1 and clinical diagnosis, Hb, hs-CRP, eGFR, TC, LDL-C, HDL-C, HbA1c and LVEF
Model 3: adjusted for variables in Model 2 and DAPT, ACEI/ARB, ARNI, antidiabetic agents and statins at discharge
Model 4: adjusted for variables in Model 3 and LM disease, multivessel disease, CTO, thrombotic disease, in-stent restenosis, target vessel selection, PTCA, number of stents, interval time from CABG to PCI and PCI success
a The HR was examined by per 1-unit increase of TyG index
b The HR was examined regarding the low TyG index group as reference
TyG, triglyceride-glucose; HR, hazard ratio; CI, confidence interval; other abbreviations as in Table 1
