Hello. Thank you for your question and welcome to HCM. I read your query and understood your concern.
Globally, the blood pressure levels accepted as normal, are as follows: 100-139 mmHg systolic and 60-89 mmHg diastolic. Every figure within this range is considered normal.
Plain physical activity or programmed exercise should be a substantial part of everyday life of every human being, since it provides a lot of physiological and psychological benefits. I would recommend you a 60-minute a day physical activity, not necessary vigorous activity, but walking, jogging, biking, swimming etc.
The thing that worried me, actually, is the blood pressure figures you provided while on a treadmill. This is a normal person's normal blood pressure at rest. Blood pressure goes up when we exercise or engage on another physical activity. A failure of blood pressure to rise during physical activity can be a sign of coronary
artery problem. Therefore, I would recommend you to do an EKG and a cardiac
stress test.
I hope I was helpful. Best regards.
Dr. Meriton
