Roger is a 59 year old Caucasian male who presented to his GP for a general check-up and had no particular symptoms of concern. In addition to a number of blood tests, Roger was examined by the doctor, including recording of his blood pressure.
The doctor measured a blood pressure of 150/100mmHg.  The GP discussed hypertension with Roger and discussed the importance of following this up.


Case questions:


1. Hypertension (in addition to a number of medical conditions) may be considered as primary or secondary. Explain these concepts giving 3 examples of secondary hypertension and their pathophysiology.


2. Roger was asymptomatic and only came for a check-up. Why is it important for this "silent disease" to be detected and appropriately treated?
