Perform a targeted exam: Vitals (including BP in both arms and legs), cardiac and chest wall exam, pulmonary exam, abdominal exam. Differential diagnosis: - Think about the five “cannot-miss” causes of chest pain: 1) ACS; 2) PE; 3) Aortic dissection; 4) Tension pneumothorax; 5) Esophageal rupture. - Then can consider a broader differential diagnosis by organ system (Table 1.5) Initial diagnostics: - ECG: Look for ST changes (ACS, pericarditis, demand), RV strain (PE), Q waves (evidence of prior ischemia) - CXR: Look for pneumonia, rib fractures, pneumothorax, widened mediastinum (can occur due to aortic dissection) - D-dimer: Use age-adjusted cutoff for patients >50 yr (age × 10 = upper limit cutoff); normal d-dimer can: Rule out PE in low to intermediate clinical probability situations Rule out aortic dissection in low risk patients (i.e., no connective tissue disease; no new murmur; no chest, abdominal, or back pain that is abrupt, severe, or ripping) CT scan: Timing of contrast differs slightly depending on whether the imaging focuses on the systemic or pulmonary arteries - CTA (CT angiography with arterial contrast) is used if most concerned for aortic dissection - CTPA (CT pulmonary angiography) is used if most concerned for PE ++Table Graphic Jump LocationTABLE 1.5Etiologies of Chest Pain by SystemView Table||Download (.pdf) TABLE 1.5 Etiologies of Chest Pain by System System Etiologies of Chest Pain Cardiac Angina: Pain due to myocardial tissue ischemia (aka supply/demand mismatch) Examples: ACS (STEMI, NSTEMI, unstable angina), stable angina, demand ischemia, vasospasm, spontanous coronary artery dissection (SCAD), myocardial infarction with non-obstructive coronary arteries (MINOCA) Characteristics: Especially concerning if “typical” features (i.e., substernal, exertional, improves with rest/nitroglycerin) Pericarditis: Pleuritic, sharp, retrosternal, relieved with sitting forward, +friction rub throughout the cardiac cycle Advanced heart failure or pulmonary hypertension (PAH): Pressure, often exertional dyspnea, syncope (with advanced PAH) Vascular Aortic dissection: Sudden onset tearing pain, radiates to the back, unequal pulses and discordant blood pressures in arms and/or legs, often occurs in the setting of hypertension or connective tissue disorders Pulmonary embolism (PE): Sudden onset, pleuritic, often associated with dyspnea Pulmonary Pneumonia/pleuritis: Lateral to midline, brief, often associated with dyspnea, cough, sputum production, fever Tracheobronchitis: Midline, burning discomfort, associated with coughing Pneumothorax: Sudden, pleuritic pain, dyspnea, decreased breath sounds. Spontaneous or associated with instrumentation (e.g., central line placement) GI Peptic ulcer disease: Burning, epigastric, relieved with food or antacids GERD: Burning, epigastric, worsened when lying flat after a meal Esophageal spasm: Pressure, tightness, retrosternal, mimics angina, often relieved by nitroglycerin (likely due to relaxant effect of nitrites on smooth muscle with resultant change in esophageal motility) Biliary disease: RUQ pain, may occur after meals Pancreatitis: Prolonged/intense epigastric/back pain, presence of certain risk factors (e.g., heavy alcohol use) Neuromuscular Costochondritis: Rare ...
