Background:
The mucopolysaccharidoses (MPS) are a group of rare inherited metabolic diseases that can cause damages in various organs including the heart. This study aimed to review the medical records of Taiwanese patients with MPS in order to evaluate the cardiovascular involvement in those patients.
Methods:
From 2000 to 2012, the medical records of 60 patients with MPS in a tertiary medical center in Taiwan were retrospectively reviewed. Data on cardiac measurements and functions were obtained from previously performed echocardiograms and electrocardiograms. Cardiac parameters were analyzed according to MPS types and patients' age.
Results:
The most frequent MPS type was type II (43%). Overall, heart conditions such as thick interventricular septum (55%), asymmetric septal hypertrophy (42%) and mitral valve prolapse (33%) were common, while cardiac enlargement was infrequently seen. Valvular stenosis/regurgitation and cardiac hypertrophy were more common in patients with MPS I, II, and VI when compared with other MPS types. Cardiovascular abnormalities including valvular deformation and thickening, thick interventricular septum and diastolic dysfunction were found to progress with age.
Conclusions:
The anatomical changes of cardiovascular systems were common in all types of MPS patients, especially in MPS I, II, and VI. Echocardiography and electrocardiography can provide us good tools for early detection and long-term follow-up for these patients.
Insights
Mucopolysaccharidoses (MPS) patients frequently experience cardiovascular issues like thickened heart walls and valve problems. Early detection via echocardiography and electrocardiography is crucial for managing these inherited metabolic diseases.
Area of Science:
- Cardiology
- Genetics
- Metabolic Disorders
Background:
- Mucopolysaccharidoses (MPS) are rare inherited metabolic diseases.
- MPS can lead to significant damage in various organs, including the heart.
Purpose of the Study:
- To evaluate cardiovascular involvement in Taiwanese patients with MPS.
- To analyze cardiac manifestations based on MPS type and patient age.
Main Methods:
- Retrospective review of medical records for 60 MPS patients (2000-2012).
- Analysis of echocardiogram and electrocardiogram data.
- Cardiac parameters assessed by MPS type and age.
Main Results:
- Type II was the most frequent MPS type (43%).
- Common cardiac findings included thickened interventricular septum (55%), asymmetric septal hypertrophy (42%), and mitral valve prolapse (33%).
- Valvular issues and cardiac hypertrophy were more prevalent in MPS I, II, and VI and progressed with age.
Conclusions:
- Anatomical cardiovascular changes are common in all MPS types, particularly MPS I, II, and VI.
- Cardiovascular abnormalities progress with age.
- Echocardiography and electrocardiography are valuable tools for early detection and long-term follow-up of MPS patients.
