Coronary Aneurysm-like Dilation with Stenosis, Anti-phospholipid Antibody Syndrome, Nephrotic Syndrome, and Polycystic Kidney: A Case Report

Abstract

Here we report a case that a young man had early onset myocardial infarction. Coronary angiography showed coronary aneurysm-like dilation and thromboembolism. After stents were implanted, his condition was complicated with repeated stent restenosis. Polycystic kidney, nephrotic syndrome and antiphospholipid antibody syndrome were also present. Antiphospholipid antibody syndrome, a risk factor for recurrent coronary thrombosis, can lead to nephrotic syndrome. Polycystic kidney can be characterized by nephrotic syndrome and may be combined with aneurysmal lesions due to genetic abnormalities. According to the multidisciplinary discussion and follow-up results, the patient was diagnosed as connective tissue diseases and secondary anti-phospholipid antibody syndrome, nephrotic syndrome, and coronary artery lesions. The patient's symptoms improved after treatment for the original disease. The management of this patient broadened our understanding of the etiology of coronary artery disease in young patients and demonstrated the importance of multidisciplinary clinical thinking.
