Outcome measures for heart involvement in systemic sclerosis

Area of Science:

• Cardiology
• Rheumatology
• Medical Imaging

Background:

• Primary myocardial involvement is frequent in Systemic Sclerosis (SSc).
• Cardiac involvement in SSc is linked to focal ischemic injury and myocardial fibrosis.
• Early detection of cardiac dysfunction is vital due to its poor prognostic implications.

Purpose of the Study:

• To review current diagnostic modalities for cardiac involvement in SSc.
• To highlight the importance of pre-clinical identification of myocardial damage.
• To discuss the role of advanced imaging and biomarkers in SSc-related heart disease.

Main Methods:

• Echocardiography with pulsed tissue Doppler for heart assessment.
• Radionuclide ventriculography for ventricular function evaluation.
• Cardiac MRI for comprehensive assessment of ventricular function, perfusion, and tissue characteristics.
• 24-h ambulatory Holter ECG for arrhythmias.
• Natriuretic peptides for early heart dysfunction detection.

Main Results:

• Echocardiography is a cornerstone, while cardiac MRI offers comprehensive multi-parametric assessment.
• Cardiac MRI is poised to become the gold standard, surpassing SPECT for myocardial perfusion.
• Conduction abnormalities are common but generally benign; arrhythmias pose a significant risk.
• Natriuretic peptides may aid in identifying early cardiac dysfunction, especially in primary heart involvement.

Conclusions:

• Cardiac involvement in SSc necessitates thorough evaluation using a combination of imaging and monitoring techniques.
• Cardiac MRI provides unparalleled insights into SSc-related myocardial pathology.
• Prompt identification and management of cardiac dysfunction are essential for improving outcomes in SSc patients.
