I have had a heart attack due to a spasm and some minor blockage. I am in very good shape. I exercise at high levels in order to reach my target heart rate .my resting rate is about 54. In fact rehab nurses couldn’t believe how high in watts.
But I still have heart disease even though my stress test is perfect and my heart is working better than most men my age. I’m still at risk because I have plaque in my arteries and I am subject to spasms that can tighten my arteries.
I remember coach Ditka of the Chicago Bears had a heart attack caused by spasms. I think that was 30 years ago?
