Hypothyroidism, Raynaud's phenomenon, and acute myocardial infarction in a young woman

We describe an acute inferior myocardial infarction in a 29-year-old woman with normal coronary arteries. She has suffered from Raynaud's phenomenon in the fingers for several years. Manifest thyroid deficiency was discovered during hospitalization. A functional-type link between hypothyroidism and myocardial infarction via vasospasm manifested as Raynaud's phenomenon is proposed as one possible etiology for the syndrome of myocardial infarction in young women.
