His father had a history of hypertension and passed away from a stroke. A follow-up appointment showed a blood pressure of 150 over 90. Alicia is a 30 year old female who came in because she’s concerned that she might be pregnant. Her pregnancy test is negative, however, her blood pressure is 170 over 90.

Okay so all three people present with hypertension. Now normal blood pressure is less than 120 systolic over 80 diastolic. According to the recent 2017 American Heart Association and American College of Cardiology guidelines, hypertension is currently defined as a blood pressure over 130 systolic and 80 diastolic. Now, typically, both systolic and diastolic pressures tend to rise or fall together, but that’s not always the case. Sometimes, you can have systolic or diastolic hypertension. This is referred to as isolated systolic hypertension or isolated diastolic hypertension.
