Insights
Cardiac Munchausen syndrome involves patients feigning cardiac symptoms, leading to numerous unnecessary procedures and potential organ damage. Long-term prognosis remains poorly understood, highlighting a critical gap in medical knowledge.
Area of Science:
- Cardiology
- Psychiatry
- Medical Ethics
Background:
- Cardiac Munchausen syndrome is a rare factitious disorder where individuals feign cardiac symptoms.
- This condition leads to extensive and often unnecessary medical interventions.
Purpose of the Study:
- To review and characterize the clinical presentation of cardiac Munchausen syndrome.
- To understand the diagnostic challenges and patient behaviors associated with this condition.
Main Methods:
- A comprehensive literature search was conducted across all languages.
- Identified cases, case series, and related articles on cardiac Munchausen syndrome.
Main Results:
- Fifty-eight cases were identified, predominantly affecting middle-aged men (93%).
- Chest pain mimicking acute coronary syndrome was the most common presentation, leading to frequent hospital admissions (average 6 per patient) and invasive procedures.
- Patients often altered their stories and left against medical advice when confronted, with 95% exhibiting deceptive behaviors.
Conclusions:
- Cardiac Munchausen syndrome results in significant patient harm through unnecessary investigations and invasive procedures.
- There is a notable lack of information regarding the long-term prognosis and management of these patients.
Objective:
To examine the reports on cardiac Munchausen syndrome for clinical characteristics.
Methods:
Cases, case series, and related articles on the subject in all languages were identified through a comprehensive literature search.
Results:
Fifty-eight cases of cardiac Munchausen syndrome were identified. Mean +/- SD patient age was 44 +/- 12 years (range, 23 to 71 years). Fifty-four patients (93%) were men. The most common presenting complaint was chest pain simulating acute coronary syndrome (86%). Syncope and dyspnea were also reported. Mostly, these patients were admitted directly from the emergency department to the coronary care unit. Acute myocardial infarction was the most common admitting diagnosis. The other admitting diagnoses were cardiac arrest and arrhythmia. The average number of hospital admissions for cardiac symptoms was 6 per patient (range, 1 to > 29 admissions). Numerous procedures including cardiac catheterization, coronary angiography, peripheral arteriography, permanent pacemaker placement, electrophysiological studies, intra-aortic balloon insertion, pulmonary artery catheter insertion, and electrical cardioversion have been performed in these patients. Twenty-four patients (41%) had history of undergoing prior multiple invasive procedures, but only 10 of these patients admitted having undergone these procedures. Ninety-five percent of patients altered their stories, with many leaving the hospital against medical advice when confronted with possibility of cardiac Munchausen syndrome as the correct unifying diagnosis. None of the patients reported for follow-up.
Conclusion:
Cardiac Munchausen syndrome results in unnecessary investigations and organ damage from unneeded aggressive procedures. There is scarce information available on the prognosis of these patients, especially in the long term.
