After undergoing a battery of tests, Clinton received two stents in a coronary artery. The low-risk procedure involved inserting small metal mesh tubes into the artery to prop it open. The stents will remain within the artery permanently as scaffolding, allowing the vessel to stay open and accommodate blood flow. (See pictures of Clinton's North Korea rescue mission...
Clinton underwent quadruple-bypass surgery in 2004 at New York Presbyterian Hospital. That procedure was also prompted by symptoms of chest pain.

In 2005, the former President underwent another operation to remove scar tissue and fluid that had built up in his body - complications of the bypass procedure.

...Thursday, a series of tests, including an angiogram, an electrocardiogram and blood tests, showed no evidence of heart attack or damage to the heart. However, one of the four bypass grafts Clinton received six years ago was completely blocked. Doctors stented one of Clinton's coronary arteries to increase blood flow to the heart...
...important to remember that blocked blood vessels are not an event but a disease," says Dr. Clyde Yancy, president of the American Heart Association, who is not involved in Clinton's care but spoke in general about what to expect after bypass surgery. "We know blockages have their own natural history, and this just highlights the need to always be at the ready...
...reducing stress to maintain heart health - new vessels can become blocked again, Yancy says, simply because heart disease is a progressive condition that is not cured by surgery. But it is that much more crucial for bypass patients to control risk factors, maintain healthy weight, lower cholesterol and blood pressure and not smoke in order to decrease the risk of future heart events. "This is a chronic condition," said Schwartz. "We don't have a cure...
