Triad of palpitation, angina, and murmur in a non-cardiac patient.

The triad of palpitation, angina, and murmur is a classical feature of cardiac pathology. However, their presence sometimes uncovers a thyroid etiology. Identification well in time decreases out-of-pocket expenditures on illness and suffering. We report a case of a 40-year-old woman who presented with fever with chills, vomiting, palpitations, and shortness of breath for the past month. Also, she described chest pain as typical of angina. Multiple diagnoses were made elsewhere, but none of the treatments resulted in the resolution of symptoms. ST changes were suggestive of ischemic pathology, cardiac MRI done showed up hypertrophied myocardium. After a negative blood culture for infective endocarditis and serology sought for fever work-up, suspicious cardiac examination with a murmur, and an abnormal thyroid profile with a thyroid scan, led to a diagnosis of Graves' disease. This case defines the triad in a noncardiac patient and emphasizes what a thyroid disease does to the heart.
