High cholesterol levels. Computer artwork of balls of cholesterol in a blood vessel. When there are high levels of low density lipoprotein (LDL) cholesterol in the blood it builds up on the sides of blood vessels hardening them,a condition named atherosclerosis. This narrows the blood vessels and may even block them,causing a heart attack if the blocked vessel is in the heart,or a stroke if it is in the brain. A group of drugs called statins can be taken to lower LDL-cholesterol. Statins inhibit the enzyme in the liver that synthesises LDL-cholesterol. They also act on the blood vessels,reducing the risk of hardened vessels rupturing or becoming blocked | |
