I had three stents and an angioplasty done on a smaller artery. Had 95%; two blockages on the Left outside descending artery and 85% on the right coronary artery. I now have no wall motion from the front mid-wall down to the bottom where the ventricles are. I have Congestive heart failure; Ischemia and high lipid count. Caused mostly from cigarettes. Yes the heart attack was the wake-up call and haven't smoked one since March 30th 2012. I smoked since 1963; quit about four times before so I smoked for about 45 yrs.
I am very fortunate to be alive today to even discuss this and i hope your nephew the most success. It was not easy; but it is worth it.
