Cardiologist is calling it a major breakthrough in cardiac medicine. Doctors will now change the way they open narrowed arteries of about 800-thousand Americans. The cypher stent will now be used in most heart patients to allow blood to flow freely in areas previously clogged or narrowed by fat, cholesterol and smoking. Although stents have been used for several years by cardiologist, the cypher stent is coated with a drug that will help reduce reblockage in the vessel. In a U.S. study , researchers found that only 9 percent of the cypher recipients experienced reblockage compared to 25 percent of those who did not have it. With these impressive results, Genesis has decided to use the new stent on area patients as early as this week. The cypher stent was approved by the Food And Drug Administration this past Thursday.
