Very high HDL cholesterol 'may be risky' in patients with heart disease

There is a point beyond which HDL cholesterol is no longer protective, cardiologists warn

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.
