CVB Clinical Medicine (except MDM) Flashcards

1
Q

A 61 year old woman with a history of smoking and diabetes presents with crushing chest pain that started with walking to the kitchen in her apartment.

What diagnostic testing would you order?

A. None

B. Electrocardiogram (ECG)

C. Non-invasive Stress Testing

D. Coronary Angiogram

E. Coronary CT Scan

A

D. Coronary Angiogram

If you did a non-invasive stress test or a coronary CT, there is high pre-test probability that you would need to do a coronary angiogram anyway

(But you would need to do an ECG first, basically on the way to the cath lab)

A. None

B. Nuclear Stress Testing

C. Stress Echo

D. Regular Treadmill Stress Test

Q

How would you find a Right Ventricle Heave on physical exam?

If you found one, what pathology might be present?

A

Palpate with the heel of your hand along the left parasternal area

Normal = you don’t feel anything

RV heave = you can feel the RV contracting. This indicates pulmonary hypertension or RV hypertorphy

Q

If a patient is not fasted, what should you calculate instead of LDL-C?

A

Non-HDL-C

You cannot determine the LDL-C in a non-fasted patient because the Friedwald equation is not accurate when TG > 400 mg/dL

Use this instead:

Non-HDL-C = [Total cholesterol] - [HDL cholesterol]

Q

Are Point of Care Tests (POCTs) more or less accurate than central lab instrumentation?

A

Usually, POCTs are considered less acurate; the central lab result is considered the reference

However, POCTs have become more accurate in recent years, and some are considered diagnostic (rather than just screening tools)

Q

What is pulsus paradoxus?

How is it diagnosed?

A

If SBP on expiration is >10 mmHg higher than SBP on inspiration

  • Basically, you are taking blood pressure but letting the air out slower (2 mmHg/second)
    • Inflate the cuff
    • Gradually deflate until Korotkoff sounds are heard, but only on expiration (this is SPB on expiration)
    • Keep deflating until Korotkoff sounds are heard continuously (this is SBP on inspiration)
    • If there is >10 mmHg difference between these two numbers, pulsus paradoxus is present

Q

How can you calculate LDL cholesterol from total cholesterol?

A

No

No change in clinical management or outcomes

76

    • Carotid is palpable
    • Jugular is not
  • Pulsations?
    • Carotid has 1 puslation
    • Jugular has 2 peaks and 2 troughs per cycle (it flickers)
  • Changes?
    • Carotid pulse does not change with respiratory cycle
    • Height of jugular flicker will change with the patient’s position and decrease with inspiration
81
Q

What does a split S2 indicate?

A

No pathology!

Splitting of S2 occurs physiologically upon inspiration.

Inspiration -> More right sided filling -> takes longer to empy -> Pulmonary valve takes longer to close than aortic valve

82

Aortic regurgitation

83

  • Supine
    • Majority of auscultation
  • Left lateral Decubitus (LLD)
    • 3rd and 4th heart sounds
    • Mitral stenosis murmur

  • Changing position = changing pain
    • Relief with leaning forward
    • More severe when leaning back/lying down
  • Radiation to the back
  • ECG changes are often present
  • History of virus/fever
88
Q

When you palpate with the heel of your hand along the left parasternal area, what are you looking for?

RV heave

Normal = you don’t feel anything

RV heave = you can feel the RV contracting. This indicates pulmonary hypertension or RV hypertorphy

89
Q

What is a point of care test?

A

Any test that can be conducted at or near the site of patient care

(If the patient has to go down the hall or across the street to the lab, it is not a point of care test)

90
Q

Which murmurs (systolic vs. diastolic) are always pathologic?

A

Diastolic murmurs; any sound heard during diastole is pathogenic

  • Aortic regurgitation
  • Mitral stenosis
