Dilated cardiomyopathy as a presenting feature of Cushing's syndrome
Insights
Cushing's syndrome rarely causes systolic heart failure, typically due to left ventricular hypertrophy. This case highlights a unique presentation of heart failure from dilated cardiomyopathy, resolving after treatment.
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Cushing's syndrome is a hormonal disorder with diverse clinical manifestations.
- Cardiac involvement in Cushing's syndrome usually involves left ventricular hypertrophy (LVH).
- Dilated cardiomyopathy is an uncommon cardiac complication of this endocrine condition.
Observation:
- A patient presented with predominant symptoms of systolic heart failure and proximal myopathy.
- Echocardiography revealed dilated cardiomyopathy, not the typical LVH.
- Hormonal evaluation confirmed Cushing's syndrome.
Findings:
- The patient exhibited systolic ventricular failure attributed to dilated cardiomyopathy.
- Proximal myopathy was a significant clinical feature.
- Successful treatment of Cushing's syndrome led to complete symptom regression.
Implications:
- This case expands the spectrum of cardiac presentations in Cushing's syndrome.
- It underscores the importance of considering dilated cardiomyopathy in affected patients.
- Effective management of the underlying endocrine disorder is crucial for cardiac recovery.
Abstract:
Patients with Cushing's syndrome can rarely present with systolic heart failure as the mainstay feature. In these patients, heart failure is usually secondary to left ventricular hypertrophy (LVH) and not to dilated cardiopathy. We herewith report a patient with Cushing's syndrome, who presented with systolic ventricular failure secondary to dilated myocardiopathy and signs of proximal myopathy as predominant features. All symptoms regressed after successful treatment.
