1

More common in men. More common over 40.

Atherosclerosis

2

Has high cholesterol content.

LDL (low density lipoprotein)

3

Good lipoprotein

HDL (high density lipoprotein)

4

There is insufficient oxygen for the needs of the heart muscle.

Coronary Artery Disease (CAD)

5

Degeneration in small arteries and arterioles. Loss of elasticity, walls thick and hard, lumen narrows.

Arteriosclerosis

6

Decrease risk for blood clot formation, decrease platelet adhesion, and blocks coagulation process.

Anticoagulant (Heparin, Coumadin, ASA)

7

Decrease LDL and cholesterol by blocking synthesis in the liver.

Cholesterol or lipid reducing drugs. Lipitor and Zocor.

8

Chest pain that occurs when there is a deficit of oxygen for the heart muscle.

Angina Pectoralis

9

Coronary artery is obstructed.

Myocardial Infarction (MI). Heart Attack.

10

Blood clot that goes throughout the body.

Embolus

11

ACE Inhibitors treat?

Hypertension, CHF

12

Remove excess water, sodium ions, block reabsorption in kidneys, and treat high BP, CHF.

Diuretics

13

Decrease BP to normal levels.

Antihypertensive drugs

14

Treats angina, hypertension, arrhythmias, prevent SNS from increasing heart activity, SLOWS HEART RATE.

Beta-blockers

15

Deviation from normal HR or rhythm.

Cardiac Arrhythmias (Dysrhthmias)

16

Block movement of calcium ions into cardiac and smooth muscle fibers.

Calcium ion channel blockers (Verapamil)

17

Provide better balance of xylem supply and demand in heart muscle.

Vasodilators (Nitroglycerin)

18

Heart sounds using stethoscope.

Auscultation

19

Assess general cardiovascular function.

Exercise stress test

20

Shows size, shape of heart.

Chest X-Ray

21

Visualization of blood flow in coronary artery.

Angiography

22

Passes catheter through a vein in the arm or leg.

Cardiac Catheterization

23

PNS - Parasympathetic

Rest and digest system.

24

CNS- Sympathetic

Heart rate goes up in this system, fight or flight.

25

HR 100-160 beats per minute

Tachycardia

26

HR 160-350 beats per minute

Atrial Flutter

27

HR over 350 beats per minute

Atrial Fibrillation

28

Extra contraction of ectopic beats of atria.

Premature Atrial Contraction (PAC)

29

Heart unable to pump sufficient blood to meet metabolic needs of body.

Congestive Heart Failure (CHF)

30

Cessation of all activity in the heart. No conduction of impulses.

Cardiac Arrest
