49 years old, family of five, and own my own software company. Had heart attack in Nov 08. Blocked artery. No idea I had it. Angioplasty and drug eluding stent. Put on Plavix, Aspirin, Coumadin, Simvastatin, Lisiniprol. Went through cardiac rehab for three months. Rehab went great. In best shape of my life. Then two months after heart attack, with one month to go in rehab, started to get terrible constriction in my throat - around my adams apple.
