I was 49 when I had my SCAD heart attack in 2011.
It was a Sunday and I had done some cardio work at the gym followed by an arm weights machine. I then did a fast walk on the treadmill and after a couple of minutes felt a pain in the centre of my chest and my left hand and forearm were numb. I stopped exercising, thinking I had pulled a muscle when using the arm weights. By the time I had showered and changed the pain had gone.
