L-Carnitine
It has been shown in studies to reduce the extent of heart damage after a heart attack as well as provide symptom relief to some people with circulatory leg pain.
Left Atrium
The upper left chamber of the heart. It receives oxygen-rich (red) blood from the lungs via the four pulmonary veins, and then sends this blood to the left ventricle.
Left Ventricle
The lower left chamber of the heart. It receives oxygen-rich (red) blood from the left atrium and pumps it into the aorta, which takes the blood to the body. The left ventricle must be strong and muscular in order to pump enough blood to the body to meet its requirements.
Left Ventricular Assist Device (LVAD)
A mechanical device that can be placed outside the body or implanted inside the body. A LVAD does not replace the heart - it assists or helps it pump oxygen-rich blood from the left ventricle to the rest of the body.
Lipid
A fatty substance that is insoluble (cannot be dissolved) in the blood.
Lipoprotein
A lipid surrounded by a protein; the protein makes it so the lipid is soluble (can be dissolved) in the blood.
Low Density Lipoprotein (LDL)
The body's primary cholesterol-carrying molecule. High blood levels of LDL increase a person's risk of heart disease by promoting cholesterol attachment and accumulation in blood vessels; hence, the popular nickname ‘bad cholesterol.’
Lumen
The hollow area within a tube, such as a blood vessel.
