Hypertension Flashcards
How do we find BP?
BP = CO x SVR
How do we find pulse pressure?
Pp = Psystolic - Pdiastolic
90-95% of people with hypertension have
Essential hypertension
When we are younger, the most important contributor to BP is
Cardiac Output
When we get older, the most important contributor to BP becomes
TPR
Stage 1 hypertension is classified as
130-139/90-99
The SBP, pulse pressure, and pulse wave velocity increase with lower
Compliance
The change in pressure of a structure with a change in volume
Compliance
Systolic BP will increase and diastolic BP will decrease with
Low compliance
Tends to increase linearly with age
Systolic BP
People with elevated SBP are at higher risk for CHD if they have higher
Pulse pressure (meaning lower diastolic pressure)
Each increment of 20/10mmHg doubles the risk of CVD across the entire BP range, starting from
115/75 mmHg
