Every year, nearly one million Americans are implanted with cardiac stents. These tiny, wiry tubes of woven metal help open the coronary arteries that supply the heart muscle with blood. Although it seems that more blood flow to the heart is always better, the final verdict on stents is more complicated. In some cases, it's better to simply say no.
Stents have become commonplace because in some cases they are really lifesaving. In most heart attacks, one of the coronary arteries completely clogs and can not deliver oxygenated blood to the heart. If the artery is not reopened immediately, the affected part of the heart degenerates into useless porridge. Because stents are the most efficient and durable arterial reopening tools, they are almost always the best treatment for heart attacks. The sooner a stent can be used, the more likely the result is likely to be. So the next time you develop pancreatic pains, do not waste time and call for an ambulance.
