Words can only go so far in describing the pain of an acute attack of angina pectoris. The real thing is an experience no one wants to have. But last year 6.2 million Americans were stricken with the condition. These restrictions result from fatty deposits building up on the arterial walls. Excessive dietary fat, lack of exercise, smoking, and genetics may all contribute to the disease.
Coronary bypasses reroute the arteries around the restricted vessels.
Arterial deposits may continue to build after a bypass as well. That percentage is expected to increase over the next decade as a swell of baby boomers enter their 60s. This was unexpected when these procedures were initiated. Refractory angina patients are increasingly elderly, have less chance of successful operations, and a greater risk of complications and death. While genetic factors may play a part in arteries clogging again, the chief culprit is the patient's lifestyle and diet.
