Former President Bill Clinton's heart surgery last winter has prompted a renewed focus on treating heart disease. Heart disease is the leading cause of death among both men and women in the United States and Europe. Over 500,000 American women die of the disease each year - twice the number of deaths from all cancer combined. In February 2010, Clinton, who has a history of heart disease, underwent a procedure to procedure to insert stents to widen narrowed his coronary arteries. The procedure is common, according to the American Heart Association, with over 70% of coronary angioplasty procedures including stenting.
Coronary angioplasty is a procedure that involves placing a catheter with a small balloon on its tip into the patient's narrowed artery under angiographic guidance. When properly positioned, the balloon is inflated and deflated, moving the plaque build-up further against the artery wall and thereby improving the flow of blood. This procedure may also be called percutaneous transluminal coronary angioplasty (PCTA), coronary artery balloon dilation or balloon angioplasty. Coronary angioplasty may be followed by stenting, a procedure in which a stent (expandable wire mesh tube) is permanently inserted into the artery to keep it open and restore normal blood flow.
