Objectives: This study aimed to investigate the 10-year risk of cardiovascular disease (CVD) by Framingham risk score (FRS) who classified as “healthy group”by Korean Occupational Safety and Health Agent (KOSHA)’ s cardiovascular risk assessment.
Methods: The subjects of this study were 1,781 male workers in a large steel company. Health status was obtained periodically through medical examinations and questionnaires. We assessed cardiovascular risk using KOSHA guidelines and calculated the 10-year risk of cardiovascular disease using the Framingham risk score for those categorized to the “healthy group”by KOSHA guideline. A closer examination of cardiovascular risk factors was performed in 62 subjects paradoxically placed in the “healthy group”by KOSHA guidelines and the“ high- risk group”by FRS.
Results: Among the “healthy group”by KOSHA’s cardiovascular risk assessment, 230(15.8%) subjects had more than 3 CVD risk factors and 62(4.2%) subjects were high risk group (more than 20%) in 10-years risk of CVD by Framingham risk score. Modifiable risk factors included cigarette smoking (96.8%), high serum total cholesterol (82.3%), high serum triglyceride (66.1%), insufficient physical activity (66.1%), and obesity (58.1%).
Conclusions: Among subjects with normal blood pressure, it seems that KOSHA guidelines underestimate CVD risk, identified by the Framingham risk score. For the effective prevention and management of CVD, modifiable risk factors, such as cigarette smoking, dyslipidemia, and obesity, need to be constructively controlled.
