Questions for Discussion:
- What additional questions regarding past medical history are important to ask?
- What portions of the physical examination are essential in the evaluation of this patient?
Further history reveals that the patient's mother developed chronic hypertension when she was 45 years old. The remainder of the history is unrevealing and the physical examination discloses no abnormalities. Repeat blood pressure at the end of the physical examination is 144/100 mmHg.
- What might explain the elevated blood pressure other than chronic hypertension?
- What is your management plan at this stage and why?
Over the next two months several blood pressure readings by the office nurse
average 150/96 mmHg.
- What is your diagnosis at this point? Answer
- What would you tell the patient at this point regarding his blood pressure?
- What laboratory tests would you order and why?
- How would you approach the management of this patient's elevated blood pressure?
- What is your goal for this patient's blood pressure and why?
After two months blood pressure multiple blood pressure determinations average 144/94 mmHg. LDL is 140 mg/dL. The EKG suggests LVH.
- How would you treat his hypertension now? Justify your choice.
- Select an initial antihypertensive agent, including dose, for each of the following patients. (Note: there is no one correct answer but be prepared to justify your choice).
- An 85 y.o. women with a persistently elevated BP of 185 / 85 mmHg.
