Reports of coronary involvement by IgG4 RD are scarce and we could find only 16 case reports in the literature. Here, we present a case of a 61-year-old lady, with no known comorbidities, who presented with rapid progression of coronary artery stenosis. Initially, she presented with mild stenosis of left anterior descending which rapidly progressed to significant triple vessel disease in 3 months. Serological workup for antibodies was negative, except for raised serum IgG4 antibodies. She was managed effectively with steroids.<\/jats:p>","DOI":"10.1055\/s-0044-1791566","type":"journal-article","created":{"date-parts":[[2024,11,20]],"date-time":"2024-11-20T00:16:51Z","timestamp":1732061811000},"page":"485-489","source":"Crossref","is-referenced-by-count":0,"title":["CT
