LPA and coronary artery disorder: Notably, within this study, the observation that no difference was found between low (<30 mg/dl) and elevated (30–50 mg/dl) Lp(a) in ACS risk differs from recent findings, where Lp(a) levels over 30 mg/dl contributed to an increased risk of coronary heart disease (44) and a linear relationship with both fatal and nonfatal cardiovascular risk (45, 46).
