1

What are the three types of Carditis?

1. Pericarditis
2. Myocarditis
3. Endocarditis

2

What is Pericarditis and the ETIOLOGY?

inflammation of pericardium -the outside layer of heart (saclike imembrane around heart)

etiology: 1. RHEUMATIC FEVER makes you at risk
2. idiopath (unknown cause)

3

What is Myocarditis?

inflammation of cardiac muscle and conduction system without evidence of MI

4

What is the etiology of Myocarditis?

1. viral or bacterial infection

5

What is the treatment for Myocarditis?

Antibiotics

6

S&S of Myocarditis?

1. dypsnea - difficulty breathing
2. fatigue
3. palpitation or racing heartrate
4. may have had an infection

7

What are the S&S of Pericarditis?

1. sharp sudden pain (pleuric) in chest from layers rubbing while breathing
2. Orthopnea
3. Pallor

8

What is Endocarditis?

inflammation of membrane lining the valves and chamber of heart

9

S&S of Endocarditis?

1. night sweats - fever for weeks
2. fatigue
3. weekness

10

Etiology of Endocarditis?

infection - group A strep bacteria

11

Treatment of Endocarditis?

1. eliminate infecting organ
2. surgery to repair valve

12

Treatment of Pericarditis?

Treat symptoms
bed rest with chest elevated w/analgesics

13

How to diagnose Pericarditis?

P=Auscultation may reveal grating sound as hear beats.

14

Diagnose Myocarditis?

Medical history - reveal upper respiratory infection.

15

Diagnose Endocarditis?

medical history reveal predisposing factors and new heart murmur

16

What is Mitral Insufficiency?

blood from left ventricle flowing back in the left atrium

17

What is Mitral Stenosis?

blood flow is obstructed from left atrium to left ventricle

18

What is the etiology of Mitral Insufficiency/Stenosis?

1. Childhood Rhuematic fever
2. infective endocarditis

19

S&S of Mitral Insufficiency/Stenosis?

1. Difficulty breathing when laying down (orthopnea)
2. large jugular veins

20

Treatment for Mitral Insufficiency?

surgical replacement with artificial valve

21

What is Aortic insufficiency?

blood flowing back into the left ventricle causing it to swell (causing left ventricular hypertrophy)

22

What is Aortic Stenosis?

Prevents blood from flowing freely from left ventricle to the Aorta. (Valve has become

23

What is the etiology of Aortic Insufficiency/Stenosis?

1. Rheumatic Fever
2. endocarditis
3. hypertension

24

What are the S&S of Aortic Insufficiency/Stenosis and how to diagnose?

S = may be asymptomatic,
1. angina - severe pain in chest
2.
D = Auscultation may reveal murmur

25

How to treat Aortic Insuff/Stenosis?

1. surgical replacement of aortic valve
2. Balloon valvuloplasty
3. assess yearly with ECG and echocardiogram

26

What is Essential Hypertension?

High blood pressure without a cause
(pressure exerted against the vessel wall)

27

Etiology of Essential Hypertension?

1. idiopathic
2. more common in african americans, obese, and stressed people

28

S&S of Essential Hypertension?

1. tinnitus (ringing in ears)
2. nocturia (urinating at night)
3. light headedness
4. tire easily

29

Diagnose Essential Hypertension?

1. blood pressure greater than 140/90mm
2. auscultation - hear abnormal sound (bruits)
3. ECG and chest x-ray will detect cardio damage

30

Treatment of Essential Hypertension?

1. lifestyle and diet changes
2. Vasodialators-relax vessels
