Chinese researchers studied all their cases of autoimmune necrotizing myopathy (AINM) over the period 2011-2022 with a focus on possible cardiac complications:
- Fifty-seven patients with AINM were included in the study,
- 56% had anti-SRP autoantibodies, 21% had anti-HMGCR autoantibodies and 23% were seronegative,
- almost half had abnormalities on cardiological check-up including cardiac rhythm and/or ventricular function disorders.
These data confirm the results of previous studies and should encourage clinicians to carry out a full cardiological check-up in the event of a diagnosis of AINM.
