A 55 year old man’s blood pressure is controlled below 140/90mmHg and above 140/90mmHg is considered high blood pressure. If conditions allow it can be controlled at the ideal blood pressure, which is below 120/80mmHg. Many 55 year old men will have progressively higher blood pressure as they get older, and keeping it below 140/90mmHg is a good range. Some 55 year olds whose blood pressure has reached the diagnostic criteria for hypertension, but is grade 1 hypertension, will need to have strict control of poor lifestyle habits, and if, on the basis of therapeutic lifestyle interventions, the blood pressure is still higher than 140/90mmHg, then medication is recommended to keep the blood pressure within the normal range.
