A month ago was getting chest pain and shortage of breath with any kind of exersion. Dr performed heart cath, (had 80+ percent blockage in LAD) and baloon agioplasty. , my tissue had grown up in between 2 of the stents, could not restent the area, The previous stents were the medicene filled ones. Why is my tissue / scare tissue continuing to form new blockages?
