Left ventricular systolic and diastolic function by echocardiogram in pseudoxanthoma elasticum

Area of Science:

• Cardiology
• Genetics
• Connective Tissue Diseases

Background:

• Pseudoxanthoma elasticum (PXE) is an inherited systemic disorder affecting connective tissue.
• Cardiac involvement is a potential complication of PXE.
• Early detection of cardiac abnormalities in PXE is crucial.

Purpose of the Study:

• To investigate cardiac function in patients with PXE.
• To identify subclinical cardiac abnormalities in PXE patients without a history of heart disease.

Main Methods:

• Echocardiography with standard measurements and tissue Doppler imaging were performed.
• Nineteen patients with PXE and no history of cardiac disease were enrolled.
• Analysis focused on systolic and diastolic function parameters.

Main Results:

• Systolic function was preserved in all patients.
• Abnormal diastolic parameters were detected in 7 out of 19 patients (37%).
• These findings suggest subclinical diastolic dysfunction in PXE.

Conclusions:

• PXE patients may exhibit diastolic dysfunction even without overt cardiac symptoms.
• Potential causes include silent myocardial ischemia or direct effects on cardiac elastic tissue.
• Further research is warranted to understand the long-term cardiac implications of PXE.
