Lecture 16: High BP Flashcards
What is Hypertension?
sustained elevation of systemic arterial blood pressure
1 in 3 adults have it
What is “Systolic Hypertension?”
Elevated BP with normal Diastolic
aka (isolated systolic hypertension)
What is “Systolic/Diastolic Hypertension?”
Elevated Sys and Dia BP
What is “Primary Hypertension?”
Elevated BP which causes other conditions
What is “Secondary Hypertension?”
a condition caused by a systemic disease process that raises peripheral vascular resistance or cardiac output
When the ventricles _____, to force open the _______ valves, they must generate sufficient _____ to exceed the BP in the major arteries
contract
semilunar
pressure
What is “Hypertrophy?”
an enlarged organ
The heart may be able to compensate for a sustained increase in _______ by hypertrophy. This enables it to _____ more forcefully and maintain a normal ____ _____ despite an abnormal impediment to ______
afterload
contract
stroke volume
ejection
What are 10 factors associated with Primary Hypertension?
1) family history of it
2) Advancing age
3) gender (males <55 and woman >74)
4) black race
5) High sodium intake
6) glucose intolerance
7) cigarette smoking
8) obesity
9) heavy alcohol consumption
10) low intake of calcium, potassium and magnesium
why does large amount of Sodium cause hypertension?
- reduces the kidney’s ability to remove water
why does cigarette smoking cause hypertension?
nicotine is a vasoconstrictor which can elevated sys and dia BP

True
Moderate Drinkers have a lower blood pressure than BOTH heavy drinkers and abstinent drinkers?
T/F
True

sympathetic
catecholamines
(epinephrine and norepinephrine)
neurotransmitters
RAA System
_______ is responsible for the _______ of the myocardium associated with hypertension
Angiotension II
