Very high levels of HDL cholesterol are paradoxically associated with a near twofold greater mortality risk in patients with coronary artery disease, according to new research.

The U-shaped association suggests that HDL cholesterol levels above 2.0mmol/L (80mg/dL) are not necessarily protective in this clinical setting, US cardiologists say.
