Hypertensive Heart Disease and Cor Pulmonale Flashcards
HYPERTENSIVE HEART DISEASE PART 1
HYPERTENSIVE HEART DISEASE PART 1
What is Poiseuille’s Law?
-Q=ΔP X r4
Flow=pressure gradient* radius^4
- If the radius decreases, the resistance to blood flow __________ and blood flow _________.
- How can we preserve blood flow if r decreases? What effect does this have on the heart?
- increases
- decreases
-Increase ΔP which means the heart has to work harder.
Why do we want to control BP?
Associated with decreased incidence of adverse cardiac events/disease.
- Systolic BP is the ________ pressure exerted against the wall of a blood vessel, while diastolic BP is the _________ pressure exerted against the wall of a blood vessel.
- What is a normal BP?
- Maximum, Minimum
- 120/80
- What is Double Product?
- What is the formula?
- Noninvasive way of measuring heart work.
- DP = HR * SBP
- What happens to the heart with HTN?
- Why is this problematic?
- The heart myocardium will hypertrophy in an effort to meet the demands of HTN.
- Problematic because it can lead to
List the BP Categories.
Normal = <120/<80 (AND) Elevated = 120-129/<80 (AND) High (Stage 1 HTN) = 130-139/80-89 (OR) High (Stage 2 HTN) = >140/>90 (OR) Hypertensive Crisis = >180/>120 AND/OR)
List some pharmalogical management of HTN.
- Diuretics
- Beta Blockers
- Calcium Channel Blockers
- ACEi
- Alpha1 blockers
- Central agents
- Aldosterone receptor blocker
What are the guidelines for using HTN medicine?
Using enough anti-HTN as needed to control BP.
- Only __% of patients seeking care for stubborn high blood pressure take all the medicine they’re supposed to be taking
- Another __% are not taking any of their blood pressure medications
- __% are somewhere in the middle!!!
- 20%
- 20%
- 60%
Why do people stop taking their anti-HTN medication?
- Side effects (orthostatic hypotension)
- Sexual function (B-blockers)
- Cost
- Doesn’t change the way they feel
- Increased age
- Gender: women greater non-adherence
- African American race
What are the 2 types of HTN?
- Essential
- Secondary
- What is the cause of essential HTN?
- It represents __% of all HTN cases.
- Unknown
- 90%
- What is the cause of secondary HTN?
- It represents __% of all HTN cases and treatment focuses on management of what?
- Caused by conditions of the kidneys, arteries, heart, or endocrine system.
- 10%, underlying cause
