Primary Cardiac Involvement in Systemic Sclerosis: Best Approach to Diagnosis

Primary cardiac involvement in systemic sclerosis (SSc) is an important cause of morbidity and mortality. Abnormalities of cardiac structure and function can be detected on routine cardiopulmonary screening that is the standard of care for SSc monitoring. Cardiovascular magnetic resonance-extracellular volume (indicating diffuse fibrosis) and cardiac biomarkers may identify at-risk patients who would benefit from further evaluation including screening for atrial and ventricular arrhythmias with implantable loop recorders. The role of algorithm-based cardiac evaluation both before and after therapeutic initiation is one of the many unmet needs for SSc clinical care.
