摘要
Background: High carbohydrate antigen 125 (CA-125) level was reported to be associated with some cardiac dysfunctions, such as chronic heart failure, but the relationship between CA-125 level and coronary heart disease (CHD) risk remains unclear. The aim of this study was to explore the potential association in a Chinese older population. @@@ Methods: In a population-based case-control study conducted in a Chinese older population, serum CA-125 levels were measured in 1177 diagnosed CHD patients and 3531 age and sex matched control subjects without CHD. @@@ Results: Serum CA-125 level was significantly higher in CHD patients than controls (P < 0.001) with adjustment for age, gender, smoking, drinking, BMI, physical activity, hypertension, dyslipidemia, diabetes mellitus, medication history and family history of CHD and myocardial infarction. CHD risk was doubled (OR: 2.10, 95% CI: 1.69-2.60) among subjects in the highest quartile compared to those in the lowest quartile of CA-125 level (P-trend < 0.001). Furthermore, CA-125 levels were associated with CHD risks in subjects with age over 60 years (OR: 2.19, 95% CI: 1.75-2.73), current smokers (OR: 2.29, 95% CI: 1.50-3.49), current drinkers (OR: 2.35, 95% CI: 1.57-3.53) and subjects with hypertension (OR: 2.04, 95% CI: 1.71-2.43). @@@ Conclusions: Elevated serum CA-125 level might be associated with increased risk of coronary heart disease in the Chinese older population. Further investigations are needed to identify the possible biological role of CA-125 in CHD development in the future.
