That sounds promising. Did you change your lifestyle in any way like food etc? I am throwing all the bad stuff outHang in there Thunderstick, you will recover. I know because I had a similar experience back in 2006. My wife was away and I was building a rock wall beside our house when I suddenly had chest pains ,shortness of breath and broke out in a cold sweat, and felt completely drained of energy. I had to sit down for about 15 min before I felt that I could walk to the house door about 20 feet away. We live 25 miles from the hospital out on a lake and there was no other houses around so I drove my truck to the hospital. They gave me somethings and then quickly sent me to Halifax by ambulance, where they wipped me on the table and inserted 2 stints to clear blockages. Up to that point of the attack I had no idea that anything was wrong with me.That was 16 years ago and I have had no problems since. I'm 82 now and I feel great and do whatever I feel like doing. I too was a non drinker, non smoker and was what I thought in good shape before it happened.
