Cardiovascular Pathophysiology Flashcards
1
Q
3 Kinds of Cardiomyopathy
A
- dilated cardiomyopathy
- hepertrophic cardiomyopathy
- Restrictive cardiomyopathy
2
Q
Dilated cardiomyopathy & Prognosis
A
- ventricle dilation & severely impaired systolic function
- Majority of deaths w/n 5 years (L heart failure)
3
Q
HCM
A
- hypertrophy of interventricular septum
- caused by HTN or valve disease
4
Q
Treatment of HCM
A
-beta blockers (to decrease HR and work)
5
Q
Dilated Cardiomyopathy Treatment
A
- salt restriction
- digitalis glycosides
- vasodilators
- diuretics
- anticoagulants
6
Q
Restrictive Cardiomyopathy
A
- rigid, non-compliant myocardium
- from infiltrative disease
7
Q
Causes of Restrictive Cardiomyopathy
A
- amyloidosis
- glycogen storage disease
- hemochromatosis
8
Q
Treatment of Restrictive Cardiomyopathy
A
- none
- treat underlying cause
9
Q
ASD
A
(atrial septal defect)
- patent foramen ovale
- R to L shunt (between atria)
- increased R heart workload
10
Q
ASD detected as:
A
-detected at birth as murmur
11
Q
ASD left untreated leads to:
A
R heart failure
12
Q
PDA
A
(patent ductus arteriosus)
- opening between pulm trunk and aorta
- remains open due to hypoxemia or premature birth
- L to R Shunt (aortic press>pulm press)
13
Q
PDA can lead to:
A
-CHF
14
Q
PDA Treatment
A
- surgery
- IV indeomethacin
15
Q
6 developmental/congenital heart diseases
A
- ASD
- VSD
- PDA
- Coarction of the Aorta
- Tetralogy of Fallot
- Endocardial Cushion Defect
