I am 33 years old, I had open heart surgery in Aug '09 to correct a birth defect in my heart, I didn't know that I had until then. One of my main arteries had to be removed, rerouted and reimplanted. Since then I had to have a stent put in Jan. '10 due to scar tissure in the artery. I've been having trouble since. My meds I'm now taking Plavix 75mg daily, Asprin 325mg daily, hydrochlorot 12.5mg daily, metoprol 25mg twice daily and I just started Ranexa 500mg twice daily. I have no energy, if I exert myself in any way the chest pain/pressure starts with sharp pains and then they radiate to the left arm and up the left side of my neck. All of my test have come back normal. This is scarring me to death and as a coal miner I'm afraid I'm going to lose my job. I just don't know what to do they said the Ranexa is kinda a last option, I have a wife and three kids to take care of, I really need help to find out whats causing this.
