Summary
Cardiac sarcoidosis can cause focal left ventricular perfusion defects, which may resolve over time. However, persistent defects and reduced ejection fraction indicate a poorer prognosis, especially in fatal cases.
Area of Science:
- Cardiology
- Immunology
- Pathology
Background:
- Sarcoidosis is a multisystem inflammatory disease.
- Cardiac involvement in sarcoidosis can lead to significant morbidity and mortality.
- Early detection and monitoring of cardiac sarcoidosis are crucial.
Purpose of the Study:
- To investigate cardiac involvement in patients with sarcoidosis.
- To assess the prognostic significance of left ventricular perfusion defects.
- To correlate imaging findings with electrocardiographic abnormalities and serological markers.
Main Methods:
- Investigated 41 patients with sarcoidosis for cardiac involvement.
- Utilized Thallium-201 Myocardial Perfusion Scintigraphy (TMPS) to assess perfusion defects.
- Performed echocardiography and Holter ECG monitoring.
- Measured Serum Angiotensin-Converting Enzyme (SACE) activity.
Main Results:
- Focal left ventricular perfusion defects were identified in 5 of 41 patients.
- Defects resolved in 4 patients over 3 years, but persisted in a fatal case.
- Reduced left ventricular ejection fraction was observed in 14 patients.
- Echocardiography showed wall dysfunction only in the fatal case.
- Holter ECG revealed abnormalities in 13 of 32 patients.
- Elevated SACE activity correlated with perfusion defects in some patients.
Conclusions:
- Left ventricular perfusion defects in cardiac sarcoidosis can be dynamic.
- Persistent defects and reduced ejection fraction are associated with poor outcomes.
- SACE activity may serve as a biomarker for cardiac sarcoidosis activity.
