Coronary vasospasm associated with uncontrolled carcinoid tumour

We report on a 74-year-old carcinoid patient who, following acute myocardia l infarction (MI) and percutaneous transluminal coronary angioplasty, suffe red recurrent episodes of chest pain and ST-segment elevation on ECG. This was accompanied by elevation of urinary 5-hydroxy-indole acetic acid. A rev iew of the patient's file revealed that during the 3 weeks prior to the MI, she had been treated inadvertently with a fivefold lower dosage of octreot ide. Following the correction of octreotide dosage, episodes of chest pain resolved immediately. We therefore suggest that this patient suffered from recurrent coronary vasospasm due to uncontrolled carcinoid tumour.
