[Echocardiographic study of heart function in systemic scleroderma]
Insights
Echocardiography reveals frequent cardiac abnormalities in systemic scleroderma patients, including reduced left ventricular function and high rates of pericarditis. Mitral valve prolapse was also notably more common.
Area of Science:
- Cardiology
- Rheumatology
- Medical Imaging
Background:
- Systemic scleroderma is a complex autoimmune disease with potential multi-organ involvement.
- Cardiac complications are a significant cause of morbidity and mortality in systemic scleroderma patients.
- Echocardiography is a crucial non-invasive tool for assessing cardiac structure and function.
Observation:
- Echocardiographic evaluation of 65 systemic scleroderma patients identified frequent abnormalities.
- Lowered left ventricular sizes and central hemodynamic indices were common, particularly in advanced disease stages (II-III).
- Pericarditis was observed in a high proportion of patients (40%), with 3/4 of those examined showing signs.
Findings:
- Specific cardiac findings included asymmetric obstructive cardiomyopathy in one patient.
- Valvular abnormalities were noted, such as mitral stenosis (1 patient), mitral insufficiency (1 patient), and aortic insufficiency (1 patient).
- Mitral valve prolapse occurred in 10.9% of patients, twice the general population prevalence.
Implications:
- Echocardiography effectively elucidates the cardiac pathology in systemic scleroderma.
- The study highlights the high prevalence of pericarditis and mitral valve prolapse in this patient cohort.
- Findings underscore the importance of routine echocardiographic screening for early detection and management of cardiac involvement in systemic scleroderma.
Abstract:
Echocardiographic investigation of 65 patients with systemic scleroderma showed that the left ventricular sizes and indices of central hemodynamics were frequently lowered in them; an increase in sizes was observed mainly in the patients with stage II-III of disease. In 3/4 of the same patients pericarditis was revealed; on the whole, it was detected in 26 (40%) examinees. One patient had changes which were typical of asymmetric obstructive cardiopathy. In location of the valvular apparatus signs of mitral stenosis were found in one patient, those of mitral insufficiency in one patient and those of aortic insufficiency in one patient. Signs of mitral prolapse were noted in 7 (10.9%) patients, i.e. twice more frequently than in the entire population. Echocardiography made it possible to specify the nature of cardiac pathology and brought to light some additional features of the involvement of different heart membranes in systemic scleroderma.
