Association between idiopathic mitral valve prolapse and panic disorder

Area of Science:

• Cardiology
• Psychiatry
• Clinical Psychology

Background:

• Idiopathic mitral valve prolapse (IMVP) is a common cardiac condition.
• Panic disorder is a prevalent anxiety disorder.
• The relationship between IMVP and panic disorder requires further investigation.

Purpose of the Study:

• To investigate the association between idiopathic mitral valve prolapse and panic disorder.
• To compare the prevalence of panic disorder in patients with IMVP versus healthy controls.
• To assess psychometric differences among patients with IMVP, panic disorder, and healthy controls.

Main Methods:

• A comparative study involving 50 patients with IMVP, 50 with panic disorder, and 50 healthy controls.
• Echocardiographic evaluation for IMVP assessment.
• Structured Clinical Interview for DSM-IV Axis I Disorders for psychiatric diagnosis.
• Administration of Symptom Check List, Beck Depression Inventory, and State and Trait Anxiety Inventory for psychometric evaluation.

Main Results:

• Panic disorder prevalence was significantly higher in the IMVP group (16%) compared to healthy controls (2%) (p=0.03).
• Patients with panic disorder exhibited the highest psychometric scores, followed by the IMVP group, which scored significantly higher than controls (p<0.001).
• Both IMVP and panic disorder groups showed similar panic attack symptoms, with no significant differences in psychometric evaluations or clinical symptoms between panic disorder cases with and without IMVP.

Conclusions:

• A potential comorbidity exists between panic disorder and idiopathic mitral valve prolapse.
• Clinicians should consider the possibility of co-occurring panic disorder when evaluating patients with IMVP, and vice versa.
• Further research may elucidate the underlying mechanisms of this association.
