Mental health is correlated with lipoprotein(a) levels in male patients with premature coronary heart disease

High levels of lipoprotein(a) (Lp(a)) is an independent risk factor for premature coronary heart disease (PCHD). It is also considered a residual risk for controlled low density lipoprotein cholesterol (LDL-C). Dietary control, exercise, and drugs have limited effects on the levels of Lp(a). Recently, mental health was found to be associated with lipid levels and increased risk of PCHD. However, the relationship between mental health and Lp(a) is still unknown. This study explored the association between mental health and Lp(a) levels in men with PCHD. A retrospective, observational study was conducted. A total of 226 male patients with PCHD, aged 49.65±3.68 years, was included in this study. The control group consisted of 230 age-matched healthy male volunteers. Serum Lp(a) levels ≥30 mg/dL, as measured by the immunoturbidimetry method, were considered high. All participants received health related quality of life (HRQoL) scores using the self-assessed 36-Item Short Form Health Survey (SF-36). The HRQoL includes both a physical component summary (PCS) and a mental component summary (MCS). Patients with PCHD were found to have higher levels of Lp(a) (51.61±33.39 vs. 26.42±21.93, P
