Objective The Japan Atherosclerosis Society (JAS) has recommended serum lipid management goals (SLMGs) based on the coronary heart disease (CHD) risk classification included in its 2007 guidelines for the diagnosis and prevention of atherosclerotic cardiovascular disease in the Japanese population (JAS GL 2007). The Japan Society of Ningen Dock created a database of subjects receiving annual health examinations. Using this database, we evaluated the lifestyles of patients with dyslipidemia by identifying risk factors for CHD development based on the JAS recommendations. Methods A total of 223,407 adults (men: 138,435; women: 84,972) aged between 20 and 79 years were enrolled in the analysis. Those who were already being treated for dyslipidemia and had a history of CHD were excluded. CHD risk factors in the JAS GL 2007, such as an advanced age, hypertension, diabetes mellitus, smoking habits, a family history of coronary artery disease, and low high-density lipoprotein cholesterol levels, were used for the evaluation. The subjects were categorized into three groups (Categories I, II and III) according to the number of risk factors other than the low-density lipoprotein cholesterol (LDL-C) level. We evaluated the percentage of goals met during primary prevention in each group. The serum LDL-C levels were calculated using the Friedewald formula. The LDL-C levels were measured using a direct homogeneous assay if the triglyceride level was ≥400 mg/dL. Results Overall, 72.9% of the subjects achieved their SLMGs. Most subjects (>90%) with no CHD risk factors other than the LDL-C level in Category I achieved their SLMGs, while less than half of the subjects in Category III achieved their goal. Conclusion Smoking cessation and medication administration should be considered in patients in Categories II and III.
