Aim: This study aimed to explore the prognostic value of leukocyte telomere length (LTL) in patients with coronary artery disease (CAD). Materials & methods: We enrolled 366 CAD patients and 76 healthy subjects in this study. LTL was measured. All subjects were followed up for 6 months for further analysis regarding major adverse cardiac events (MACEs). Results: CAD patients had a significantly shortened LTL compared with healthy subjects (p < 0.05). The area under the curve for LTL prediction of MACEs was 0.769 (p < 0.001), with a shorter LTL being an independent predictor of MACEs (Cox proportional hazards regression, hazard ratio: 2.866; p < 0.001). Conclusion: LTL could be considered as an independent predictor of short-term MACEs in CAD.
