I know you’ve probably done it already, but pin your Cardiologist to the wall and discover EXACTLY what caused your issues. They’re often reluctant to go into detail, yet once you know the precise causes you can tailor your rehab to ensure the chances of a repeat are minimised.
Don’t believe anything you’re told. CHECK EVERYTHING yourself. The NHS is not what it was in my day.
Stay positive, keep smiling, hope to see you in the flesh one day 🙂
