BACKGROUND: The aim of this study was to investigate the association between the monocyte-to-high-density lipoprotein-cholesterol ratio(MHR) and the outcomes of patients with coronary artery disease(CAD) who were treated with percutaneous coronary intervention(PCI).

METHODS: A total of 5679 CAD patients from CORFCHD-PCI, a retrospective cohort study (Identifier: ChiCTR-ORC-16010153), who underwent PCI were included in the study and divided into three tertiles according to their MHR values. The primary outcome was long-term mortality after PCI. The main secondary endpoints were stroke, readmission, and major adverse cardiovascular events(MACEs), defined as the combination of cardiac death, recurrent myocardial infarction, and target vessel reconstruction. The average follow-up time was 35.9±22.6 months.

RESULTS: Patients were divided into 3 groups according to MHR tertiles: the 1st tertile (MHR<0.4;n=1290), 2nd tertile(MHR≥0.4 to 0.61; n=1878) and 3rd tertile(MHR>0.61;n=1870). The all-cause mortality(ACM) incidence was significantly lower in the 1st and 2nd tertiles than in the 3rd tertile(adjusted HR=0.658, [95%CI:0.408-0.903],P=0.009 and HR=0.712, [95%CI: 0.538-0.941], P=0.017, respectively). Cardiac mortality(CM) occurred in 235 patients: 60(3.1%) in the 1st tertile group, 74(3.9%) in the 2nd tertile group and 101(5.4%) in the 3rd tertile group. There was a significant difference in the CM incidence between the 1st tertile group and the 3rd tertile group(HR=0.581, [95% CI: 0.406-0.832], P=0.003), and there was also a difference in the CM incidence between the 2nd tertile group and the 3rd tertile group (HR = 0.690, [95%CI:0.506-0.940], P=0.019).

CONCLUSION: The present study indicated that an increased MHR was independently associated with long-term mortality in CAD patients who have undergone PCI.
