Key result
Microscopic polyangiitis can rarely manifest as dilated cardiomyopathy with apical sparing on strain imaging.
Why the study?
The report aims to describe a case of dilated cardiomyopathy with severe systolic dysfunction in a young patient with MPA, highlighting an apical sparing GLS pattern.

No
This case highlights the importance of systematic cardiovascular evaluation, including echocardiography with GLS, for early detection of myocardial involvement and apical sparing patterns in patients with ANCA-associated vasculitis.
Apical sparing GLS may aid diagnosis and monitoring in MPA cardiomyopathy; hypothesis-generating and requires validation in larger cohorts.
In this context, the aim of this report is to describe a case of dilated cardiomyopathy with severe systolic dysfunction in a young patient with MPA, highlighting the finding of an apical sparing GLS pattern and its diagnostic and follow-up implications.

Costa et al. (2026) conducted a case report in Microscopic Polyangiitis and Dilated Cardiomyopathy (n=1). Microscopic Polyangiitis was evaluated on Cardiac manifestation. Microscopic polyangiitis can rarely present with dilated cardiomyopathy and severe systolic dysfunction, characterized by an apical sparing pattern on global longitudinal strain.
