Besides both being ex-presidents, that is…
Both have now had coronary stents implanted.
News came today that George W. underwent a surgical procedure to have a coronary stent placed. The stent was placed because of narrowing in one coronary artery. Bush was not having any symptoms, but the diagnosis was made after a stress test done as part of a routine check-up.
Many were surprised by this announcement as President Bush was felt to be very physically fit. He exercised nearly everyday, even as president, and continued his exercise routine after he left office.
The ex-president did well with the procedure and is expected to be released from the hospital tomorrow.
It occurs when the blood vessels that supply blood to the heart muscle itself (the coronary arteries) become narrowed by a build up of plaque. Plaque is made up of cholesterol, fat, calcium and other substances from the blood.
Narrowing of the arteries leads to a decrease in blood supply to the heart muscle. This can lead to the symptoms of chest pain (angina) or even heart attack if the narrowing is severe enough, or if part of the plaque breaks off and blocks a smaller part of the artery.
In a coronary artery bypass, surgeons connect a blood vessel (taken from elsewhere in the body) to either side of a blocked artery to allow blood to flow freely again.
With an angioplasty, a catheter is inserted into the large artery in the groin, and is threaded up into the coronary arteries. The catheter has a small balloon on its tip. The balloon is inflated at the blockage site in the artery to flatten the plaque against the artery wall. After treatment, the guide wire, catheter, and balloon are removed. The hospital stay and recovery time for angioplasty is shorter than that of bypass. But about 35% of patients are at risk for more blockages in the treated area.
A stent procedure is frequently used along with balloon angioplasty. This involves placing a mesh-like metal device into an artery at a site narrowed by plaque. The stent is mounted onto the balloon-tipped catheter, threaded through an artery, and positioned at the blockage.
When the balloon is inflated, stent is opened. Then, the catheter and deflated balloon are removed, leaving the stent in place. The opened stent keeps the vessel open and stops the artery from collapsing.
Here’s a great video showing how the procedure is done:
