A

Myocarditis

32
Q

What is the BEST way to differentiate between Myocarditis and Pericarditis?

A 
Myocarditis = Increased Cardiac Enzymes
Pericarditis = Cardiac Enzymes Normal

**Because cardiac enzymes are in the muscles!

  • Post-Viral
  • Feels better leaning forward
  • JVD, distant heart sounds, rub
35
Q

This is a cause of chest pain common in post-menopausal women. The pain is anginal in quality. It is due to DECREASED coronary flow reserve at microvascular level (versus obstructive dz in larger coronary arteries).

A

Microvascular Dysfunction (Syndrome X)

36
Q

This is a cause of chest pain commonly precipitated by emotional or physical stress. Classic anginal symptoms in patients with or without risk factors. It will show positive cardiac enzymes. It could be triggered by a sympathetic storm. Sometimes called Takotsubu CM.

A

Stress-Induced CM

Commonly after being drunk we see this

37

  • Worse with inspiration, cough, position, directly pressing on it
  • Sharp, stabbing, ripping, shredding
61
Q

Review: Hx of CP

Precipitating Factors

A
  • Exertion – think angina, esophageal
  • Eating – think upper GI disease; postprandial, GI or cardiac
  • Swallowing – likely esophageal
  • Position – pleuritic when supine, moving, coughing; think: pneumonia, pneumothorax, pleurisy
62
Q

Review: Hx of CP

Mitigating Factors

A
  • Antacids – GI
  • Nitro – cardiac, GI
  • “GI cocktail”
  • Leaning forward – pericarditis
63
Q

Review: Hx of CP

Radiation

A
  • Cholecystitis – R shoulder with concomitant RUQ pain
  • Aortic Dissection – interscapular pain
  • Neck, jaw, throat, teeth, upper extremity – ischemia (may be GI as well)
64
Q

Review: Hx of CP

Severity

A
  • Pain intensity does not correlate to severity of ischemia
  • Relief with nitro does not ensure that it’s a cardiac cause and…
  • Vice versa
65
Q

Review: Hx of CP

Assc Symptoms

A
  • Diaphoresis more common in MI than esophageal

- Nausea, belching, vomiting, dysphagia may be seen in MI or GI

66
Q

Review: Hx of CP

Physical Exam Findings

A
  • Tachypnea, tachycardia, vitals
  • Hyperventilation
  • Carotid arteries, elevated JVP
  • Lung exam: hyperresonance, absent breath sounds, trachea, crackles
  • Cardiac exam: impulse location, parasternal heave, murmur, friction rub
  • Abdomen: check epigastric area, RUQ
  • Extremities: bilateral blood pressures in upper & lower ext
67
Q

Review: Hx of CP

Normal EKG

A
  • Reduces pretest probability of acute MI but not unstable angina
  • Dissection, PE classically normal
68
Q

Review: Hx of CP

Abnormal EKG

A
  • ST elevation, Q-waves is predictive of current/old MI
  • Non-specific findings (ST depression, T-inversion)
    • May lead to noncardiac diagnoses
69
Q

Review: Hx of CP

Chest Radiograph

A
  • Rule out pneumothorax, dissection, pneumomediastinum
  • Pulmonary infiltrate, mass, adenopathy
  • Pulmonary edema suggestive of CHF from acute LV dysfunction from a myocardial infarction

Q

T/F: Most routine tests for chest pain (EKG, CXR, enzymes) are sufficient to exclude this condition!!!

A

False, they are not.
