1

Angina

caused by ischemia--> caused by Athersclerousis

2

Symptoms of MI

elbow pain, nausea, pressure in the chest,

3

MI

Death of Myocardial tissue

4

3 Types of Angina

1. Chronic stable angina- exersize induced
2. Unstable angina- Happens while resting
3. Vasospastic- Chest pain when under stressed

5

Heart Failure

prevent after MI

6

Nitrates

Dilates the coronary artery, and the periphery--> resulting in decrease work load on the heart muscle.

7

Nitrate Forms

1. trans dermal patches- remember to remove old patch, make sure since is intact to prevent increased absorption. Place on upper chest.
2. Sub lingual- causes headaches, 1 every 5 minutes up to 3 times for treatment of angina, causes burning and stinging under the tongue, make sure the patient lets it completely dissolve, assess for therapeutic effect. store in a dark place and good for 3 months after opened.

Coronary Artery disease

Nursing role with

10

Beta Blockers

-Decrease the heart rate
-Effect the myocardial contractility
-Used after an MI to reduce sudden death arrhythmia

11

Beta Blocker Indications

-Angina
-Antihypertensive
-Protect heart after MI

12

Beta Blocker Adverse effects

Bradycardia- do not give if HR is below 60 and contact provider.
Hypotension- 90/60 too low
AV Block- Monitor EKG, Heart sounds or irregular HR
Hyper/Hypo-glycemia- DM patients are at high risk (Monitor CBG)
Impotence- biggest cause of non-compliance
Depression-

13

Calcium Channel Blockers (CCB)

Increases O2 through coronary artery vasodilation, and help in the periphery. As a result supply will equal demand

14

CCB Indications

-Angina
-Hypertension
-Supraventricular tachycardia when HR goes above 120
-Coronary artery Spasms
-Short term help with A-fib

15

A-Fib

The heart is not contracting properly

16

CCB Adverse effects

-Hypotension, dizzyness
-Palpatations- from the increase in HR
-Bracycardia-
-Constipation and Nausea

17

Heart Failure-Right

Right sided is secondary to left failure right sided major causes of Right sided heart failure is COPD and Right heart infarctions.

18

Heart Failure- definition

The heart is unable to pump blood to meet the bodies needs.

19

Heart failure causes

MI
Valve deficiency
CAD
Pulmonary Hypotention
DM
Hypertention

20

Therapy for heart failure

-Positive of inotropic effect- showing signs of mypcardial contractions
- Positive chronotropic effect- Increase heart rate
Negative chronoptropic effect
Positive Dromotropic- increases rate of cardiac conduction
Negative dromotropic effect slows the conduction

21

ACE inhibitors

Prevents sodium and H2O absorption, potassium is reabsorbed.

22

Antiotensin 2 receptor blockers

block angiotensin 2 and cause vasodilation- used short term

23

Phosphodiesterase Inhibitor (Milrinone)

primarily used in ED
Positive inotropic effect
increased stroke volume
decreased preload

24

Inotropic

Muscle contractions

25

Chronotropic

Affecting the rate of rhythmic movements, such as the heartbeat.

26

Dromotropic

Relating to or influencing the conductivity of nerve fibers or cardiac muscle fibers.

27

Digoxin

+inotropic, -chronotropic, -dromotropic
