Mitral valve prolapse in psoriatic arthritis

Area of Science:

• Rheumatology
• Cardiology
• Genetics

Background:

• Seronegative arthropathies, including psoriatic arthritis, are associated with aortic valve lesions.
• Echocardiography is a key diagnostic tool for evaluating cardiac structures.

Purpose of the Study:

• To investigate the prevalence of aortic valve lesions in patients with psoriatic arthritis.
• To assess the incidence of mitral valve prolapse (MVP) in this patient cohort.

Main Methods:

• Echocardiography was performed on 25 patients diagnosed with psoriatic arthritis.
• Patient demographics, disease characteristics, and HLA tissue typing were recorded.
• A control group of 32 psoriatic patients without arthritis was included for comparison.

Main Results:

• No aortic valve lesions were identified in the psoriatic arthritis group.
• Mitral valve prolapse (MVP) was detected in 14 patients (56%) with psoriatic arthritis, significantly higher than the control group (6.4%).
• No significant differences in age, psoriasis duration, or arthritis duration were observed between patients with and without MVP.

Conclusions:

• Psoriatic arthritis is not associated with aortic valve lesions.
• Mitral valve prolapse (MVP) is highly prevalent in patients with psoriatic arthritis.
• Further research is warranted to understand the link between psoriatic arthritis and MVP.
