Flashcards in heart failure and heart muscle disease Deck (20):
1

def. heart failure

clinical syndrome with multiple causes
- inability to pump blood forward at suff, rate to meet body demands

2

3 functional classes of HF

1. HF with reduced ejection fraction - dilated heart
2. HF with preserved EF - stiff heart
3. R HF
- can be pure, but often in combo

3

causes of HF

often the end stage of multiple patho processes
- patho changes are due to attempted changes
- these changes beget further changes

4

what are 2 main types of cardiomyopathies

primary - usually genetic
secondary
- many ways to damage the myocytes

5

3 classic STRUCTURAL forms of cardiomyopathies

1. dilated pattern - large chamber
2. hypertrophied pattern - chamber small, wall thick
3. restrictive pattern - stiff heart - amyliod
- can all be caused by many different disease processes

6

what is hypertrophic cardiomyopathy

specific type of heart muscle disease - genetic basis
- other forms of hypertrophy can make a hypertrophied pattern - aquired
1. hypertensive
2. fabry's disease
3. LVH due to aortic valve disease

7

features of dilated cardiomyopathy

- remodelling and hypertrophy
- forward and backward failure
- can be prmary or secondary

8

what is major complication of dilated chambers

development of mural thrombi

9

what might be seen in patho of different causes of DCM

- amyloid
- hemochromatosis - Fe
- myocardidis - lymphocytes

10

what is most common pattern of hypertrophic cardiomyopathy

asymettric septal hypertrophy
- scar common

11

what is issue with scarring

arrythmogenic foci
- prone to sudden death

12

what is hypertrophic obstructive cardiomyopahy

- clincial diagnosis
- mitral valve agaisnt septum causing obs. to blood flow

13

2 variants of obstructive

1. apical - at base only
2. concentric - all around base

14

2 Tx opf obstructive

1. alcolohol ablation of the vein supplying the muscle
2. shave it off in surg

15

what is hypertrophied heart

NOT hypertrophic cardiomyopathy
- due to HT
- common in pop

16

what is restrictive cardiopyopathy

infiltration of fibrois tissue or other substance into wall andmakes it stiff
- sarcoidosis
- amyoidosis

17

what is HF with preserved ejection fraction (4 feat.)

diastolic HF
1. impaired relaxation - can't fill
2. incr. LV stiffness -
3. atrial dysfunction - esp if dilated
4. F>M

18

what is another type of cardiomyopathy

arrythmogenic RV cardiomyopathy - ARVC

19

what is aRVC

fibro-fatty depostion into the R and L vent
- maybe heritable

20

what is another name for R sided HF

cor pulmonale
- typically secondary to pulm disease or congenital heart disease with R to L shunt
