Q

What is angina?

A
  • Angina is chest pain or discomfort caused when your heart muscle doesn’t get enough oxygen-rich blood. It may feel like pressure or squeezing in your chest. The discomfort also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. But, angina is not a disease.

What is orthopnea?

A

Orthopnea or orthopnoea is shortness of breath (dyspnea) that occurs when lying flat, causing the person to have to sleep propped up in bed or sitting in a chair.

Q

What is paroxysmal nocturnal dyspnea (PND)?

A

Paroxysmal nocturnal dyspnea or paroxysmal nocturnal dyspnoea (PND) refers to attacks of severe shortness of breath and coughing that generally occur at night. It usually awakens the person from sleep, and may be quite frightening.

Q

What is cyanosis?

A

Cyanosis refers to bluish discoloration of skin, nail beds and mucous membranes. Normally haemoglobin carries most of the oxygen in blood. This oxygen carrying capacity of haemoglobin in the blood (present in the arteries) is called oxygen saturation.

20
Q

What is pallor?

A

an unhealthy pale appearance

21
Q

What is edema?

A

Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema.

Edema happens when your small blood vessels become “leaky” and release fluid into nearby tissues. That extra fluid builds up, which makes the tissue swell.

22
Q

What is nocturia?

A

Nocturia is a condition in which you wake up during the night because you have to urinate. This condition becomes more common as people age and occurs in both men and women, sometimes for different reasons.

23
Q

What are some risk factors for cardiovascular disease?

A 
Elevated serum cholesterol 
Elevated blood pressure
Blood sugar levels above 130
Diabetes Mellitus
Obesity
Smoking
Sedentary lifestyle
Stress/depression
Low socioeconomic status
Diet high in saturated fat
Family history
24
Q

Which gender is more at risk for coronary artery disease?

A

-females
Coronary artery disease leading cause of death in women
1 out of 2.4 due to cardiovascular disease
1 out of 29 breast cancer (women perceive breast cancer as greater risk)

All women should be screened for risk factors

25
Q

What atypical symtoms are women experiencing when they have heart disease or myocardial infarction?

A 
Angina: hot/cold burning sensation; tender to touch in back shoulders, arms or jaw
Often no chest discomfort or pain
Nausea vomiting, indigestion, shortness of breath or extreme fatigue
Throbbing above waist
Breathlessness
Cold sweat
Feeling of impending doom
Edema
26
Q

What is the assessment order for a cardiovascular assessment?

A 
Assessment Order
Inspection
Precordium and neck vessels
Palpation
Precordium and neck vessels
Extremities
Auscultation
Heart sounds
27
Q

What side of the heart does the jugular vein tell you about?

A

right side of the heart

observe for distention

28
Q

What are the expected findings when palpating the carotid artery (remember one side at a time)?

A

smooth contour
amplitude is 2+ moderate
equal bilaterally

29
Q

What are the abnormal findings when palpating the carotid artery?

A

diminished pulse (decreased stroke volume, 1+)
significantly strong pulse (4+)
unequal bilaterally

30
Q

When palpating the precordium what are the expected and unexpected findings?

A
  • precordium is the outer aspect of the heart so palpate apex, left sternal border, and base
  • expected: nothing
  • abnormal: thrill: vibration (purring cat): indicates turbulent blood flow. heave: sustained forceful thrust
31
Q

What are the expected and unexpected findings when auscultating the carotid artery?

A 
Lightly place the bell on the carotid
At the angle of the jaw
At the midcervical area
At the base of the neck
Expected findings
Hear nothing
Abnormal findings
Bruit – blowing swishing sound; turbulent blood flow
32
Q

What pattern is used in the auscultation of heart sounds?

A

utilize the diaphragm and bell in a z pattern

33
Q

What are the expected findings when auscultating heart sounds?

A 
S1 (lub) 
Closure of AV valves
Start of systole (contraction)
Loudest at apex
Can coordinate with carotid pulse
S2 (dub) 
Closure of semilunar valves (aortic/pulmonic)
End of systole
Loudest at base
Split can be normal with inspiration, especially in young patients
Rate and Rhythm
Regular – sinus rhythm
Sinus arrhythmia: irregular rate in young adults and children; increases with inspiration, decreases with expiration
60-100 bpm
34
Q

What are the unexpected findings when auscultating heart sounds?

A

Irregular rhythm or rate:
Bradycardia is less than 60
Tachycardia is greater than 100
Arrhythmias: irregularity of rhythm
EXTRA HEART SOUNDS (Diastolic)
S3
Heard immediately after S2, early in diastole (filling)
Difficulty with filling causes vibration when AV valves open
S4
Heard immediately before S1, end of diastole
Ventricles resistant to filling
Clicks
May indicate valve dysfunction
Opening snaps
Valve having difficulty opening; stenosis
Prosthetic heart sounds
Sounds made by artificial valves; check history
Pericardial friction rub
Grating sound; inflammation of pericardium; very painful

35
Q

What are murmurs?

A

whooshing sound as a result of turbulent bloodflow

36
Q

What is a stenosis?

A

flow through a constricted area/vessel

37
Q

What is a mitral valve prolapse?

A

Regurgitant (Regurgitant fraction is the percentage of blood that regurgitates back through the aortic valve to the left ventricle due to aortic insufficiency, or through the mitral valve to the atrium due to mitral insufficiency.) or backward flow

38
Q

What is shunting?

A

septal wall defects

39
Q

What are the causes of murmurs?

A

Whooshing sound as a result of turbulent blood flow
3 basic types of flow “pathology”
Flow through a constricted area/vessel (i.e. stenosis)
Regurgitant or backward flow (i.e. mitral valve prolapse)
Shunting (i.e. septal wall defects)
Other non-pathological causes of murmurs
Exercise
Decreased blood viscosity

40
Q

How are abnormal heart sounds described?

A 
Location 
Timing
Duration
Frequency
Intensity
Quality
Change with reposition?
41
Q

What are some causes of heart failure?

A

decreased cardiac output

kidney’s compensatory mechanism

42
Q

What is decreased cardiac output going to cause?

A

Heart fails as a pump; Circulation becomes backed up and congested

Heart unable to pump enough blood to meet metabolic demands

43
Q

What are the kidney’s compensatory mechanisms?

A

Abnormal retention of sodium and water to compensate
for the decreased cardiac output increases blood volume
and venous return, causing further congestion

44
Q

What are some acute causes of heart failure?

A 
Myocardial infarction (heart attack), dysrhythmias, pulmonary emboli
causes direct damage to the heart’s contracting ability
45
Q

What are some chronic causes of heart failure?

A

Hypertension, coronary artery disease (CAD), valve disorders
Chronically working against increased pressure

46
Q

What are the clinical manifestations of left sided heart failure?

A 
Left ventricular dysfunction
Back up into pulmonary veins: LUNGS
Pulmonary edema, crackles, wheezes
S3 & S4 sounds
Weakness, fatigue
Dyspnea
Shallow resp; rate 32-40, dry cough; low O2 sat
Paroxysmal Nocturnal dyspnea, orthopnea
Nocturia
47
Q

What are the clinical manifestations of right sided heart failure?

A 
Less common
Right ventricular dysfunction
Back up into systemic circulation: ABDOMEN
JVD, liver spleen, GI, peripheral edema
Weight gain, ascites
Anasarca
Fatigue
Dependent, bilateral edema
Nausea
Anorexia, bloating
