Hi, I just turned 56, I had triple bypass in April 2010 in a German hospital. 2 months later back in the States I had chest pain again, I was admitted and found out the new LIMA that was placed closed(failed entirely) therefore they put two stents one month and another two stents a monther after and ballooned the lower diagonal in my LAD, the bad artery. In Feb. 2011 I received another stent between the others and ballooned the side diagonal, what a mess!! Doctors have no clue why this is happening, they are puzzled as I am. However, my main concern is, my sex life has been altered since the surgery and of course all the medications I have been taking, I was very active prior to that. I just can t get up as often as I want and it does not get as hard. Your diagnosis is much appreciated
