Acute myocardial infarction in a young man with ankylosing spondylitis: A case report.

BACKGROUND: Ankylosing spondylitis (AS) is a chronic progressive inflammatory disease that mainly affects the spine and sacroiliac joints. To the best of our knowledge, AS with acute myocardial infarction (AMI) has rarely been reported. Here, we report an unusual case of AS with AMI in a young patient.

CASE SUMMARY: A 37-year-old man was admitted to the Department of Rheumatology and Immunology of our hospital on March 14, 2020, for low back pain. Further evaluation with clinical examinations, laboratory tests, and imaging resulted in a diagnosis of AS. Treatment with a non-steroidal anti-inflammatory drug and a tumor necrosis factor inhibitor partially improved his symptoms. However, his back pain persisted. After 6 wk of treatment, he was admitted to the emergency room of another hospital in this city for sudden-onset severe chest pain consistent with a diagnosis of AMI. Angiography revealed severe narrowing of the coronary arteries. Surgical placement of two coronary stents completely relieved his back pain.

CONCLUSION: AS can cause cardiovascular diseases, including AMI. It is important to consider the cardiovascular risks in the management of AS.
