When we think about heart health, many of us are familiar with the idea of "hardening" arteries or the buildup of calcium in the blood vessels. But there's another, more dangerous culprit lurking within your arteries that often goes unnoticed: soft plaque. Unlike its calcified counterpart, soft plaque can be more unpredictable and potentially life-threatening, even when you feel perfectly healthy.

Lp(a), or Lipoprotein(a), can be thought of as a tiny package of cholesterol in your blood, wrapped in a unique protein called apolipoprotein(a). It's a wildcard in heart health— Lp(a) levels are mostly determined by genes and don't change much with diet or exercise.

High levels of Lp(a) can increase your risk of heart attack, but there's a catch: the amount of risk associated with high levels of Lp(a) depends on your ethnicity.

Most doctors will tell you a LDL Cholesterol of 100 mg/dL is "good", leading many of us to believe that we have eliminated the risk of this disease if we hit this number. But this one-size-fits-all approach grossly oversimplifies the complexity of cardiovascular risk and leaves many of us unknowingly at high risk for heart-related events.
