What is lipoprotein a?
Lipoprotein A, commonly called Lp(a), is a major independent genetic risk factor for cardiovascular disease (CVD) and atherosclerosis. It is a relative of LDL or bad cholesterol. The difference between Lp(a) and low-density lipoproteins (LDL) is apolipoprotein apo(a), a glycoprotein structurally similar to plasminogen, the precursor of plasmin, the fibrinolytic enzyme. The optimum laboratory level should be under 20 mg/dl and preferably under 14 mg/dl.
