A middle-aged male with a blood pressure reading of 180/80 mmHg may be described as:

The reading of 180/80 mmHg indicates that the individual falls within the category of hypertension. According to medical guidelines, hypertension is defined as having a systolic blood pressure (the first number) that is 130 mmHg or higher or a diastolic blood pressure (the second number) that is 80 mmHg or higher. In this case, while the diastolic number is 80 mmHg, the extremely high systolic number of 180 mmHg classifies this individual as hypertensive, specifically in the hypertensive crisis category (stage 3 hypertension).

This reading suggests that the person has an increased risk of cardiovascular issues, and even immediate medical intervention may be necessary, depending on the context and any accompanying symptoms. Therefore, describing the patient as hypertensive is accurate and reflects the seriousness of the condition.
