I had a stent put in July 2009. This year I had 3 more stents put in July 2010. Has anyone had stents that close together? I ask when in the hospital if this was unusual. I was told it was not the norm, and they do not know why some people do this. I do not have high blood pressure, cholesterol good, thin, and exercise. They told me it was the genes. They told me I was a complicated case. I also had open heart surgery 2006. Those grafts were about 50% blocked. They did not put stents in them. I am not sure what someone can do when their genes are the problem.
