Rheumatoid Arthritis Revealed by Myocardial Infarction in a Type 1 Diabetic Patient

The association of rheumatoid arthritis (RA), Hashimoto thyroiditis and type 1 diabetes mellitus (T1D) is rarely reported. Herein, we report the case of a sixty-year old female, with a history of non-complicated type 1 diabetes and well-substituted Hashimoto thyroiditis who had a myocardial infarction at the age of 48 year-old. Our patient did not have classical risk factors for coronary heart disease, clinical and laboratory investigations showed the diagnosis of rheumatoid arthritis. The association of RA and the autoimmune endocrinopathies is not a fortuitous finding and coronary disease in well equilibrated T1D patient should encourage physician to search another aetiology.
