numbers in blood pressure
This is an old saying for blood pressure levels and comes from a time when doctors understood less about the risks of high blood pressure. It is not true â an optimal blood pressure level is 120/80mmHg or lower, and high blood pressure is 140/90 mmHg or higher, whatever your age. The lower your blood pressure the lower your risk of heart attack, heart failure, stroke and kidney disease will be. For a blood pressure chart of readings, click here.
