Abstract

Background and aimsWe aimed to investigate whether neck circumference (NC) can predict metabolic syndrome (MetS), coronary calcification and lesion, and major adverse cardiovascular events (MACEs). MethodsA total of 867 patients with acute coronary syndrome (ACS) over 60 years old from the Second Hospital of Shandong University, who had undergone coronary computed tomography, were randomly selected for a retrospective analysis. The subjects were divided into male and female groups, NC quartile 1–4 groups (Q1-Q4 groups), non-multivessel coronary disease (non-MVCD) and multi-vessel coronary disease (MVCD) groups. ResultsAfter adjusting for potential confounders, NC was associated with risk factors promoting coronary artery disease (CAD) and coronary artery calcification score (CACS). The severity of CAD increased by 0.202 times and 0.372 times for each unit of NC in male and female groups, respectively. Compared with the lower CACS group, the risk of coronary calcification increased by 0.139 times, and MVCD increased 0.268 times, with each unit increase of NC. Except for all-cause death, there were significant differences between the Q1-Q4 groups in the prevalence of all primary endpoints, cardiogenic death, unexpected re-hospitalization of heart failure, ACS recurrence or unplanned revascularization, and non-fatal stroke (p log-rank <0.01). In view of the overall trend, with the increase of NC quartiles, the prevalence of MACEs gradually increased (all p < 0.01). ConclusionsNC is closely associated with MetS and its components, coronary calcification and lesion degree, and MACEs. NC could be used as surrogate of CACS to predict the coronary condition and prognosis of elderly patients with ACS.
