1

3 Kinds of Cardiomyopathy

-dilated cardiomyopathy
-hepertrophic cardiomyopathy
-Restrictive cardiomyopathy

2

Dilated cardiomyopathy & Prognosis

-ventricle dilation & severely impaired systolic function
-Majority of deaths w/n 5 years (L heart failure)

3

HCM

-hypertrophy of interventricular septum
-caused by HTN or valve disease

4

Treatment of HCM

-beta blockers (to decrease HR and work)

5

Dilated Cardiomyopathy Treatment

-salt restriction
-digitalis glycosides
-vasodilators
-diuretics
-anticoagulants

6

Restrictive Cardiomyopathy

-rigid, non-compliant myocardium
-from infiltrative disease

7

Causes of Restrictive Cardiomyopathy

-amyloidosis
-glycogen storage disease
-hemochromatosis

8

Treatment of Restrictive Cardiomyopathy

-none
-treat underlying cause

9

ASD

(atrial septal defect)
-patent foramen ovale
-R to L shunt (between atria)
-increased R heart workload

10

ASD detected as:

-detected at birth as murmur

11

ASD left untreated leads to:

R heart failure

12

PDA

(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

PDA can lead to:

-CHF

14

PDA Treatment

-surgery
-IV indeomethacin

15

6 developmental/congenital heart diseases

-ASD
-VSD
-PDA
-Coarction of the Aorta
-Tetralogy of Fallot
-Endocardial Cushion Defect

16

VSD

-most common congenital heart disease
-opening between ventricles
-blood goes from L to R vent (due to pressure)

17

VSD detected as:

-murmur

18

VSD can lead to:

-L &/or R heart Failure if not treated

19

Coarction of the Aorta

-fibrous constriction on descending aorta
-increase pressure above and decrease press below
-BP UE>BP LE

20

Treatment for Coarction of Aorta

-surgery

21

Coarction of Aorta can cause

-cor pulmonale & heart failure

22

2 Types of Valvular Disease

-stenosis
-regurgitation/insufficiency

23

Valve:
Stenosis

-stiffening of valves
-narrowing/constriction-->valves hard to open
-obstructs blood flow & chamber prior to valve works harder

24

Valvular Stenosis often due to:

-scar/abnormal deposits on valves
