Summary
Cardiac assessment in polymyositis-dermatomyositis (PM-DM) revealed infrequent cardiac involvement. Non-invasive techniques showed minimal abnormalities in a small patient cohort, suggesting limited cardiac impact.
Area of Science:
- Cardiology
- Rheumatology
- Immunology
Background:
- Polymyositis-dermatomyositis (PM-DM) is an idiopathic inflammatory myopathy.
- Cardiac complications can occur in autoimmune diseases, but their prevalence in PM-DM requires further elucidation.
Purpose of the Study:
- To prospectively assess cardiac involvement in patients diagnosed with polymyositis-dermatomyositis (PM-DM).
- To evaluate the frequency and type of cardiac abnormalities using non-invasive methods in this patient group.
Main Methods:
- Prospective study involving fourteen patients with PM-DM.
- Cardiac assessment utilized non-invasive techniques, including electrocardiography and echocardiography.
Main Results:
- One patient exhibited electrocardiographic findings consistent with Long-Ganong-Levine syndrome and supraventricular premature beats.
- Echocardiography revealed late systolic prolapse of the posterior mitral leaflet in one patient and paradoxical interventricular septal movements in another.
Conclusions:
- Cardiac involvement appears to be infrequent in patients with polymyositis-dermatomyositis.
- Non-invasive cardiac assessments in PM-DM patients showed a low incidence of significant cardiac abnormalities.
