Differential Diagnosis for Chest Pain in a 40-year-old Female

Single Most Likely Diagnosis

  • Myocardial Bridging or Microvascular Coronary Dysfunction: Given the high troponin level (Trop 3000) and an unremarkable cardiac catheterization for coronary artery disease (CAD), myocardial bridging or microvascular coronary dysfunction could be a plausible explanation. These conditions can cause chest pain and elevated troponin levels without showing significant blockages on a cardiac catheter.

Other Likely Diagnoses

  • Pericarditis: This condition can cause chest pain and elevated troponin levels. The pain is often sharp and can be relieved by sitting up and leaning forward.
  • Pulmonary Embolism (PE): Although less likely given the context, PE can cause chest pain and elevated troponin if there is associated right ventricular strain.
  • Acute Coronary Syndrome (ACS) with Spontaneous Coronary Artery Dissection (SCAD): SCAD can occur without significant atherosclerotic disease and may not always be visible on initial cardiac catheterization.

Do Not Miss Diagnoses

  • Aortic Dissection: A life-threatening condition that requires immediate diagnosis and treatment. The chest pain is often described as tearing or ripping.
  • Pulmonary Embolism (PE): Repeated here because, although mentioned under other likely diagnoses, it is crucial not to miss due to its high mortality rate if untreated.
  • Esophageal Rupture: A rare but potentially fatal condition that can mimic cardiac chest pain.

Rare Diagnoses

  • Takotsubo Cardiomyopathy (Stress Cardiomyopathy): A condition where the heart muscle becomes weakened and cannot function properly due to extreme emotional or physical stress.
  • Coronary Artery Spasm: Also known as variant angina, this condition involves recurrent chest pain due to transient coronary artery spasm.
  • Mitral Valve Prolapse with Regurgitation: While not typically causing chest pain directly, in rare cases, it can lead to complications that result in chest pain.
