Table 2. Analysis of risk factors for MACEs in patients with coronary heart disease.

Variable	B value	Standard error	Wald	P value	RR (95% CI)
Age ≥80 years	2.517	0.392	41.295	<0.001	12.39 (5.75–26.69)
LVEF <50%	2.167	0.385	31.589	<0.001	8.73 (4.10–18.58)
Coronary artery plaque burden >33.3%	1.452	0.331	19.188	<0.001	4.27 (2.23–8.18)
FAI (HU)	0.077	0.015	26.238	<0.001	1.08 (1.05–1.11)
Multivessel CAD	1.143	0.322	12.566	<0.001	3.14 (1.67–5.90)

33.3% was the median of the coronary artery plaque burden. CAD, coronary artery disease; CI, confident interval; FAI, fat attenuation index; HU, Hounsfield units; LVEF, left ventricular ejection fraction; MACE, major adverse cardiovascular event; RR, relative risk.
