Cardiac abnormalities in mixed connective tissue disease
Insights
Mixed connective tissue disease (MCTD) patients often show cardiovascular issues like pericarditis. Noninvasive tests reveal a high prevalence of cardiac abnormalities in these individuals.
Area of Science:
- Cardiology
- Rheumatology
- Internal Medicine
Background:
- Mixed connective tissue disease (MCTD) is an autoimmune disorder with diverse clinical manifestations.
- Cardiovascular involvement is a recognized but not fully characterized complication of MCTD.
Purpose of the Study:
- To assess the prevalence and types of cardiovascular abnormalities in patients with MCTD using noninvasive techniques.
- To identify the most common cardiac findings in this patient population.
Main Methods:
- Noninvasive cardiovascular diagnostic methods were employed.
- Electrocardiography (ECG) and echocardiography were utilized to evaluate cardiac structure and function.
Main Results:
- Cardiovascular abnormalities were detected in 38% of the 16 MCTD patients studied.
- Common findings included pericarditis, asymmetric septal hypertrophy, and left ventricular (LV) dilatation.
- Borderline abnormalities were noted in 31%, while 31% showed normal results across all techniques.
- Steroid-responsive pericarditis was the most frequent clinical abnormality, observed in 25% of cases.
Conclusions:
- MCTD patients exhibit a significant prevalence of cardiovascular abnormalities detectable by noninvasive methods.
- Pericarditis, often responsive to steroids, is a key cardiac manifestation in MCTD.
- Routine noninvasive cardiac evaluation may be warranted for patients diagnosed with MCTD.
Abstract:
Sixteen patients with mixed connective tissue disease (MCTD) were studied using noninvasive cardiovascular techniques. Cardiovascular abnormalities including pericarditis, asymmetric septal hypertrophy, and LV dilatation were found in 38 percent of the study group. Borderline ECG and echocardiographic abnormalities were present in 31 percent of the study group, and the remaining 31 percent were normal by all study techniques. MCTD patients have a high prevalence of cardiovascular abnormalities when studied noninvasively. The most common clinical abnormality is a steroid-responsive pericarditis, present in 25 percent of our series.
