I had a nuclear stress test last December along with a ultrasound of my heart. I got a great report and found my heart actually pumps above average.
I do have a right carotid artery I have to watch. Otherwise okay.
I had all those tests for years because I had my first heart attack at 44. I was with a heart group at Eisenhower Medical Center in Palm Desert CA, the hospital that was built for Ike. They found nothing as I had check ups every six months. I finally got to the point I couldn't walk across a room with out setting down, all this was happening and I had no chest pain at all. I insisted an Angiogram be done and it was revealed that I had 95% blockage of the main artery that demanded surgery. I refused surgery and they sent the Stent man in who spent a couple hours drilling the artery out enough to get the stent tool in, which he did and 4 hours later I was at a poker tournament. I was 70 years old at the time and I am now 81 so maybe you should take their advice with a grain of salt. Do the stents and don't believe all he non invasive test results, the only way to know for sure is to look inside.
PS I went back the next day to do all the smaller blockages and they gave me the before and after pictures, so I have proof. I had a redo of the Angio a couple years ago and seem to be doing fine.
