Pseudohypertension (Osler’s Sign) Isolated systolic hypertension (ISH):

1. Pseudohypertension is when only systolic blood pressure (>140) is elevated.

2. Pseudohypertension is almost always found in older patients.

3. As people get older, the walls of the arteries sometimes get very thick, and calcium may be deposited in the arterial wall (arteriosclerosis). This makes the arteries very stiff and difficult to compress.

4. Because measuring blood pressure depends on measuring how much force it takes to compress an artery, having thick, difficult-to-compress arteries falsely elevates the sphygmomanometer reading.

5. It is not benign Q: It has doubles risk of MI, triples risk of CVA

Treatment: Diuretics, Calcium channel blocker
