Fat is an essential nutrient used by the body for many functions including energy, thermal insulation, vital organ protection, cell structure, and function. It is recommended that less than 30% of food calories come from dietary fats, which are present in foods of both animal and vegetable origin. (See also Saturated Fat; Monounsaturated Fat; Polyunsaturated Fat; and Omega-3 Fatty Acids.)
Femoral
Pertaining to the femur or groin. An incision in the femoral artery allows a physician to insert a treatment device - such as a balloon catheter with stent - and place it at the site of a lesion.
Femoral Artery
The femoral artery starts at the top of the thigh, runs along the front, before passing to the back of the thigh, and running behind the knee.
Fibrillation
Fibrillation is when the heart beats so quickly and chaotically that it cannot effectively pump blood. Atrial fibrillation is a frequent cause of arrhythmia and often stems from hypertensive heart disease or pericarditis. It can usually be treated with drug therapy. Ventricular fibrillation is a much more serious condition, which can lead to cardiac arrest or death of heart muscle (myocardial infarction).
