A middle-aged woman presented with chest pain, elevated troponin-T of 1037 ng/L (normal <14 ng/L; to convert to micrograms per liter, multiply by 1), and anterior T-wave inversion on electrocardiography. She was a smoker with hypertension and kidney dysfunction, with a history of left-sided paresthesia.

Coronary angiography demonstrated unobstructed coronary arteries. Cardiovascular magnetic resonance (CMR) imaging revealed subendocardial midinferolateral late gadolinium enhancement with corresponding hypokinesis consistent with a partial-thickness myocardial infarction. Prolonged Holter monitoring showed no evidence of atrial fibrillation.
