May feel like pressure or squeezing in your chest
Pain also can occur in your shoulders, arms, neck, jaw, or back, may even feel like indigestion

Answer 6

angina

Question 7

angina types

Answer 7

Types
Stable
Unstable
Variant
Microvascular

Question 8

is a symptom of an underlying heart problem
may be a major warning sign
usually of coronary heart disease, but not a disease itself

Answer 8

angina

Question 9

Most common type of angina
Occurs when the heart is working harder than usual
Has a regular pattern (referring to how often and severity)

Answer 9

stable angina

Question 10

Doesn’t follow a pattern
May occur more often and be more severe than stable angina
Can occur with or without physical exertion, often when sleeping or resting, comes as a surprise
Rest or medicine may not relieve the pain
Very dangerous and requires emergency treatment
Is a sign that a heart attack may happen soon

Answer 10

unstable angina

Question 11

rare and can be severe
spasm in a coronary artery causes this type of angina
usually occurs while sleeping at night
Medicine can relieve this type of angina

Answer 11

variant angina (Printzmetal’s)

Question 12

can be more severe and last longer than other types

Medicine may not relieve this type of angina

Answer 12

microvascular angina

Question 13

Often referred to as heart disease

Coronary Blood Supply
Coronary arteries supply the heart muscle with nutrients and oxygen by circulating blood.
Coronary arteries can become diseased or damaged
Damage may be related to atherosclerosis
hardening of the arteries
plaque builds up inside the arteries
May cause heart attacks, ischemic strokes, heart failures, arrhythmias, heart valve problems

Answer 13

coronary artery disease

Question 14

Damage to the heart muscle
Due to lack of blood to the heart
Often occur as a result of coronary heart disease
Plaque can rupture, causing a blood clot to form
Large enough clot can completely block coronary artery
If not treated quickly, affected portion of heart muscle begins to die, and healthy heart tissue is replaced with scar tissue

Answer 14

heart attack (mechanical!)

Question 15

Heart Attack Symptom Progression

Answer 15

Heart attacks can start slowly
Symptoms can be mild, or more intense and sudden
Symptoms may also come and go over several hours

Question 16

Heart Attack Symptom: Men & Women

Answer 16

The most common symptom in both men and women, is chest pain or discomfort (angina)
In the center or left side of the chest
1/3rd who had heart attacks did not experience chest pain
these are more likely to be older, female, or diabetic

Upper body discomfort: one or both arms, back, shoulder, neck, jaw or upper part of stomach (above the belly button)
Shortness of breath
Breaking out in a cold sweat
Feeling unusually tired for no reason, sometimes for days
Nausea and vomiting
Light-headedness or sudden dizziness

***Women may likely have shortness of breath, nausea and vomiting, unusual tiredness, and pain

Question 17

Other Heart Attack Symptoms

Answer 17

Upper body discomfort
Pain or discomfort in one or both arms, back, shoulder, neck, jaw or upper part of stomach (above the belly button)
Shortness of breath
Breaking out in a cold sweat
Feeling unusually tired for no reason, sometimes for days
Nausea and vomiting
Light-headedness or sudden dizziness
Chest pain or discomfort (angina) that doesn’t go away or changes from its usual pattern

Question 18

Heart can beat too fast, too slow, or with an irregular rhythm
Typical heart rate (heartbeat) = 60 -100 times per minute
Can beat faster with exercise
Can slow down while sleep
Normal: slows down and speeds up
A heartbeat that is:
Too fast: tachycardia
Too slow: bradycardia
Sometimes heart is too slow and sometimes too fast: Tachycardia-bradycardia syndrome

Answer 18

Heart Arrhythmias

Question 19

Symptoms:
Feeling faint/tired
Light-headed or passing out
Shortness of breath
Chest pain or discomfort
Palpitations (skipped beats that feel like thumping, fluttering, racing heart)
May have no symptoms

Answer 19

heart arrthymias

Question 20

Causes of this
Heart disease
Infections or fever
Physical/emotional stress
Drugs and other stimulants (caffeine, tobacco, alcohol, amphetamines, etc.)
Genes

Answer 20

heart arrythimias

Question 21

impact of arrthymias

Answer 21

Can be serious or even life threatening
heart may not be able to pump enough blood to the body
atria to quiver instead of contract

Question 22

Two types: Heart Arrhythmias

Answer 22

Ventricular: Starts from heart’s ventricles
Supraventricular: Starts outside or above the ventricles
- Atrial fibrillation

Question 23

Heart Arrhythmias tests

Answer 23

EKG: Records the heart’s rhythm
Ultrasound: Picture of the heart’s structure and function

Question 24

Treatment for Heart Arrhythmias

Answer 24

Cardiac ablation (heart tissue causing faulty heartbeat is removed)
Cardioverter defibrillator (ICD): inserted in chest; resets the heart rhythm

Question 25

Atrial Fibrillation (AF or AFib)

Answer 25

”Fibrillate“ definition = super fast HR!
AFiB can
Increase the risk of forming blood clots leading to strokes, or heart failure because of blood pools in the atrium
Cause chest pain or heart failure

Cardiac ablation
works by scarring or destroying tissue in your heart that triggers an abnormal heart rhythm

Question 26

Sudden Cardiac Arrest (SCA)

Answer 26

Heart suddenly and unexpectedly stops beating
Is an electrical malfunction of the heart, disrupting the heart’s normal rhythm
If untreated, this abrupt loss of heart function results in sudden cardiac death

95% of people who have SCA die from it - most within minutes
SCA is not the same as a heart attack
Heart attack occurs if blood flow to the heart muscle is blocked
During a heart attack, the heart usually does not stop beating
However, SCA may occur after a heart attack

Question 27

Symptoms of SCA

Answer 27

Symptoms:
Prior: Racing heartbeat, dizziness, or nothing
During: sudden collapse, loss of conscious, no pulse, no breathing

Question 28

Heart conditions that can lead to SCA

Answer 28

CAD
Enlarged heart
Valvular heart disease
Congenital heart disease
Electrical 

The most common heart rhythm at the time of cardiac arrest is an arrhythmia in a ventricle causing the ventricle to quiver instead of pumping blood

Question 29

Risk Factors of SCA

Answer 29

illegal drugs such as cocaine, nutritional imbalance (low potassium), chronic apnea, chronic kidney disease
More common in males

Question 30

Heart Valve Disease

Answer 30

Birth defects, age-related changes, infections, or other conditions cause one or more heart valves to not open fully or close; blood leaks back into the heart
Congenital heart valve disease: valves don’t form properly (not enough tissue flaps, wrong size/shape, may have an opening in which blood can get through)
Many people do not have any symptoms until middle-age or older

Question 31

3 Types of heart valve disease problems:

Answer 31

Regurgitation (backflow) occurs if a valve doesn’t close tightly
Backflow is most often caused by prolapse (flap of the mitral valve flop or bulge back into an upper atrium)

Stenosis occurs if the flaps of a valve thicken, stiffen, or fuse together

Atresia occurs if a heart valve lacks an opening for blood to pass through

Question 32

Heart Valve Disease Symptoms

Answer 32

The main sign of heart valve disease is a heart murmur (abnormal heart sound)

fatigue, SOB especially under exertion
swelling in your ankles (lower extrem) + neck

Question 33

Congestive Heart Failure

Answer 33

fails to properly pump blood

Form of cardiovascular disease that results in the decreased ability of the heart to pump blood forward or the ability to fill the heart with blood in a cyclical manner
= organ damage

In addition, fluid will start to accumulate in the lungs, SOB = tissue damage

Heart failure can result from a heart attack, but also from chronic uncontrolled high blood pressure, or heart valve disease

Question 34

Congestive Heart Failure Symptoms

Answer 34

Dyspnea (shortness of breath)
Blood “backs up” in the pulmonary veins because the heart can’t keep up, causes fluid to leak into the lungs
Persistent coughing or wheezing
Body edema
As blood flow out of the heart slows, returning blood in the veins backs up, causing fluid to build up in the tissues.
Tiredness, fatigue
Heart can’t pump enough blood to meet the needs of body tissues
Lack of appetite, nausea
Digestive system receives less blood, causing problems with digestion

Question 35

Heart Disease Diagnostics

Answer 35

Electrocardiogram (EKG or ECG)
measures electrical activity of the heartbeat. With each beat, an electrical “wave” travels through the heart.
A normal heartbeat on ECG will show the timing of the top and lower chambers

Holter Monitoring or Ambulatory ECG or Ambulatory EKG
Documents and describes abnormal electrical activity in the heart during daily activities to help doctors determine the condition of the heart.

Chest x-ray
Determines whether the heart is enlarged or if fluid is

Echocardiogram (echo)
Device placed on the chest that uses ultrasound to produce images of heart
images size, structure and motion
Helps gather information about arrhythmias
Cardiac tomography (CT or CAT scan)
Diagnostic-imaging tests to gather images of the heart.
creates three-dimensional (3-D) images that can show blockages caused by calcium deposits in coronary arteries
Exercise stress test
Treadmill test to monitor heart function while walking on a treadmill
Heart rate, breathing, blood pressure, and how tired you become when exercising

Question 36

Cardiac Catheterization known as

Answer 36

Cardiac Catheterization (Cath) is also known as Heart Cath, Angiogram (Angio) or Arteriogram

Question 37

Coronary angioplasty or stents known as

Answer 37

percutaneous coronary intervention

Question 38

Coronary angioplasty or stents

Answer 38

is a procedure used to open clogged heart arteries
by inserting and inflating a tiny balloon to the clogged artery to widen the artery
Often combined with the permanent placement of a small wire mesh tube (stent) to help prop the artery open and decrease the chance of it narrowing again.
Some stents are coated with medication to help keep the artery open
Can also be used during a heart attack to quickly open a blocked artery

Question 39

Coronary Bypass Surgery

Answer 39

Coronary artery bypass surgery (CABG)
Open chest surgical procedure - one or more blocked coronary arteries are bypassed by a blood vessel graft
restores blood flow to the heart
goals of the procedure:
to relieve symptoms of coronary artery disease (including angina)
enable the patient to resume a normal lifestyle
to lower the risk of a heart attack or other heart problems

Question 40

Types of bypass grafts

Answer 40

Internal mammary arteries
most common, best results

Radial (arm) artery
ulnar and radial arteries
Most people receive blood to their arm from the ulnar artery and will not have any side effects if the radial artery is used

Saphenous veins
Minimally invasive saphenous vein removal does not require a long incision. One to two incisions are made at the knee and a small incision is made at the groin

Question 41

During CABG Surgery

Answer 41

During surgery, the heart-lung bypass machine (called “on-pump” surgery) takes over for the heart and lungs
allows blood flow
while heart’s beating is stopped so the bypass procedure can be performed
Or off-pump procedure (see notes)

Question 42

Heart Valve Disease Treatment

Answer 42

valve repair or valve replacement

Valve repair preserves the patient’s valve and leaflets
Repair is most often possible for mitral or tricuspid valve regurgitation.

Question 43

Congestive Heart Failure Treatment

Answer 43

Lifestyle measures
1st steps may include limits on the amount of fluids consumed (including alcohol)
and reductions in dietary sodium (less than 2,000 mg per day)
And regular exercise
Medications. Medications will depend on your specific condition (see notes)
