ABSTRACT

Objective To explore the influence of metabolic syndrome on the risks of cardiovascular disease ( CVD) events and all-cause mortality. Methods In this prospective cohort study, urban residents aged 40-79 years in Guiyang were followed-up for three years. The end-points were CVD events and all-cause mortality. COX proportional hazards model were used for the corresponding hazard ratios ( HRs ) of CVD events and all-cause mortality. Metabolic syndrome was defined according to the 2005 International Diabetes Federation ( IDF ) criteria. Results A total of 7313 subjects were included. 146 cases of CVD events and 80 cases of all-cause mortality were recorded. After adjusting for gender, age, smoking, alcohol consumption, and blood lipid levels, the metabolic syndrome increased the risks of CVD events and all-cause mortality. The HRs were 1.43 (P=0.037) and 1.25 (P=0.418) , respectively. As compared metabolic syndrome with non-metabolic syndrome, an increased risk of CVD events was found. The HR was 1.43 (P=0.013). No significantly increased risk of all-cause mortality was found in subjects with metabolic syndrome. Conclusion The metabolic syndrome was associated with increased risk of CVD events and there was no significant increase in all-cause mortality. Metabolic syndrome is an important risk factor for CVD events.
