What is LDL-C (and why is it called bad cholesterol)?

LDL-C stands for low-density lipoprotein cholesterol. Over time, high levels of LDL-C can lead to a buildup of plaque in the arteries, which can burst and cause reduced blood flow to the heart or brain. If high levels of LDL-C are left unchecked, this may lead to serious cardiovascular events, like heart attack or stroke.

If I already had a heart
attack or stroke, am I still
at risk
of another?

Yes. If you have cardiovascular disease, you’re still at risk for future heart attacks or strokes, especially if your LDL-C is too high. Your risk level depends on different factors, including your medical history and whether you have additional conditions. Your doctor can help you determine your risk level.

Am I at very high risk?

Different factors can put you at very high risk for another heart attack or stroke (see the full chart below for some of the most common ones). If you are at very high risk, an LDL-C below 55 mg/dL is recommended by the American College of Cardiology, along with the American Heart Association and other Medical Societies to reduce the risk of another heart attack or stroke.
