HDL good, LDL bad: High density lipoprotein cholesterol (HDL) is protective and low density lipoprotein cholesterol (ldl) is a risk factor for heart disease. Total cholesterol is more or less a sum of these two values plus a contribution from triglycerides.

Lipids: In general HDL helps keep fatty deposits from forming in blood vessels and LDL helps form fatty deposits in blood vessels. Blocked heart blood vessels by fatty deposits and their evolution cause heart disease.
