Hypertension Flashcards
Normal blood pressure:
120
80
Prehypertension: 120–____ mm Hg systolic, 80–___ mm Hg diastolic
139
90
Stage 1 HTN: ________ mm Hg systolic, _______ mm Hg diastolic
140–159
91–99
Stage 2 HTN: ______ mm Hg systolic, _____ mm Hg diastolic
≥160
≥100
______________ correlates with the stroke volume and the compliance of the aorta
Systolic blood pressure
Name the Primary determinants of the stroke volume.
Preload
Afterload
Contractility of the heart
Compliance of the aorta _________ with age because of reduced elasticity in the aorta
decreases
Increase in SBP is caused by three factors. Name them.
Increase in preload
Increase in contractility
Decrease in the compliance of aorta
Decrease in SBP is caused by three factors. Name them.
Decrease in preload
Decrease in contractility
Increase in afterload
Name the condition in which afterload in increased.
Severe Aortic stenosis
_____________ correlates with the volume of blood in the aorta during diastole
Diastolic blood pressure
Diastolic BP depends on three factors. Name them.
State of contraction (tonicity) of the SMCs in the PVR
arterioles
The viscosity of blood
The heart rate (HR)
What factors increase DBP?
Vasoconstriction of SMCs Increased viscosity (poycythemia) Increased heart rate
Increasing heart rate ________ (increases/decreases) filling of the coronary arteries, leaving a _________ (greater/lesser) volume of blood in the aorta during diastole.
decreases
greater
What factors decrease DBP?
Vasodilation of the PVR arterioles
Severe anemia, which decreases the viscosity of blood
Decreasing the heart rate (HR)
