Cholesterol fat particles. Cholesterol is mainly carried in the bloodstream by lipoproteins. When there are high levels of low density lipoproteins (LDL,bad cholesterol) in the blood it builds up on the walls of the blood vessels,hardening them (atherosclerosis). This narrows the blood vessels and may block them,causing high blood pressure and an increased risk of heart attack | |
