A Proposal for the Optimal Management Target for Serum Non-High-Density Lipoprotein Cholesterol Level in Low-Risk Japanese Workers
Open accessAbstract
AIM: The Japan Atherosclerosis Society Guidelines for the Diagnosis and Prevention of Atherosclerotic Cardiovascular Diseases 2012 (JAS Guidelines 2012) indicate that the management target for serum non-high-density lipoprotein cholesterol (non-HDLC) level is 30 mg/dL higher than that for low-density lipoprotein cholesterol (LDLC) level. However, it remains unclear whether this value is applicable to subjects at a low risk of cardiovascular disease. This study aimed to propose the optimal management target for serum non-HDLC level in low-risk Japanese subjects. METHODS: Among 20,909 subjects who underwent annual medical checkup at a Japanese company in 2008, we analyzed the data of 17,023 subjects (14,352 men, mean age 37.8±8.6 years) in risk category I according to the JAS Guidelines 2012. The correlation between LDLC and non-HDLC levels was examined. RESULTS: A strong correlation was found between LDLC and non-HDLC levels (r=0.95, p<0.001). The following regression equation for calculation of non-HDLC was obtained from linear regression analysis: non-HDLC (mg/dL)=1.09×LDLC (mg/dL)+7.79. According to this equation, the optimal management target for non-HDLC level corresponding to that for LDLC level (160 mg/dL) was 180 mg/dL. A multiple logistic regression analysis revealed that age, obesity, habitual alcohol intake, and current smoking were significantly associated with non-HDLC ≥180 mg/dL. CONCLUSIONS: The management target for non-HDLC level is recommended to be set at 20 mg/dL higher than that for the LDLC level (i.e., 180 mg/dL) in low-risk Japanese subjects.

A decrease in the incidence of cardiovascular events is proportionate to the decrease in LDL-C level, regardless of pretreatment LDL-C level and individual absolute risk.
“Meta-analyses conducted by the Cholesterol Treatment Trialists' Collaboration on large-scale clinical trials using statins confirmed that a decrease in the incidence of cardiovascular events was proportionate to the decrease in LDL-C level, regardless of pretreatment LDL-C level and individual absolute risk177–179, 348).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
