Though I've not read that watching weight and blood pressure is recommended, it may be best to keep active according to your doctor's advice, as well as waching your diet to prevent the gain in weight that so many of us experience as we age, same too with keeping cholesterol within the guidelines provided by your doctor.

I've been afflicted by PVCs all my life, I can't smoke cigarettes, drink alcohol or coffee, eat much chocolate, take cold medicines, and a bunch of other limitations.

Keep in touch with your doctor and ask if you should be doing anything different to protect your future health proactively.
