Acute chest pain. Aggravated by movement and/or breathing. Physical exam reveals tenderness to palpation. Likely diagnosis?
  • Costochondritis
  • M: Treatment? (1)
    • Analgesics (e.g. NSAIDs, acetaminophen) along with reassurance that it should resolve within a few weeks

Acute chest pain. Incited by exertion/stress. Relieved with rest. Likely diagnosis?
  • Stable Angina
  • M: First-line treatment? (+2 Others?)
    • Beta-blockers. Other options include nondihydropyridine CCBs or nitrates.
Acute chest pain. Not relieved with rest or nitroglycerin. EKG reveals ST-depressions. Labs show negative cardiac enzymes. Likely diagnosis?
  • Unstable Angina
  • M: Initial treatment? (5)
    • MONA BASH: Nitrate, antiplatelets, beta-blocker, statin, and heparin
    • Optional: Morphine if severe pain, oxygen if SaO2 less than 90, lasix if pulmonary edema without hypovolemia
    M: Definitive treatment within 24-72 hours?
    • Reperfusion (e.g. percutaneous coronary intervention)
Acute chest pain. Episodic and often occurs suddenly at night. Resolves spontaneously after several minutes. Likely diagnosis?
  • Vasospastic (Prinzmetal) Angina
  • A: Risk factors? (3)
    • Risk factors include cigarettes, cocaine, and triptans.
    P: Mechanism?
    • Intrinsic hypercontractility of coronary artery smooth muscles that leads to vasospasms
    D: Possible finding on an EKG? (1)
    • ST segment elevation
    M: Treatment to abort an episode? (1)
    • Nitroglycerin
    M: Treatment for prophylaxis? (1)
    • Calcium channel blockers (CCBs)
Acute chest pain. EKG reveals ST-depressions. Labs show elevated cardiac enzymes. Likely diagnosis?
  • Non-ST Elevation Myocardial Infarction (NSTEMI)
  • Subendocardial infarction
  • myocardial infarction patterns, CC-BY-3.0
Acute chest pain. EKG reveals ST-elevations. Labs show elevated cardiac enzymes. Likely diagnosis?
  • ST Elevation Myocardial Infarction (STEMI
  • Transmural infarction
  • myocardial infarction patterns, CC-BY-3.0

Shortness of breath. Aggravated by laying flat. Sometimes wake up at night gasping for air. Exam reveals wheezes and bibasilar crackles. Likely diagnosis?
  • Acute Decompensated Heart Failure (ADHF)
  • C: Common findings on physical examination?
    • Physical examination can reveal bibasilar crackles and/or wheezes on auscultation, peripheral edema, jugular venous distention, S3 or S4 heart sounds
    M: Treatment?
    • LMNOP: Lasix (furosemide), morphine, nitroglycerin, oxygen supplementation, positioning (sitting upright)

Palpitations. EKG reveals “early P waves that differ in morphology from normal sinus P waves”. Likely diagnosis?
  • Premature Atrial Complexes
  • premature atrial contraction, public domain
