Progression of hypertrophic cardiomyopathy to congestive cardiomyopathy: case report
The New Zealand Medical Journal
|November 27, 1985
Insights
Hypertrophic cardiomyopathy can progress to dilated cardiomyopathy over 18 years, leading to heart failure and arrhythmias. This case highlights the dynamic nature of cardiac remodeling in hypertrophic cardiomyopathy.
Area of Science:
- Cardiology
- Clinical Medicine
- Pathophysiology
Background:
- Hypertrophic cardiomyopathy (HCM) is a primary cardiac condition.
- It is characterized by unexplained left ventricular hypertrophy.
Observation:
- A patient with HCM presented with chest pain and dyspnea.
- Over 18 years, a progressive loss of cardiac murmurs was noted.
- In the final year, the patient developed dilated cardiomyopathy.
Findings:
- The progression culminated in congestive heart failure.
- Supraventricular and ventricular tachyarrhythmias were observed.
- This suggests a potential transition from a restrictive to a dilated phenotype.
Implications:
- HCM may undergo significant remodeling over time.
- This progression can lead to end-stage heart failure.
- Understanding these transitions is crucial for managing HCM patients.
Abstract:
A case of hypertrophic cardiomyopathy presenting with chest pain and dyspnoea was followed for 18 years. During this time the patient showed a progressive loss of cardiac murmurs and over the last 12 months of life developed a dilatated cardiomyopathy associated with congestive heart failure, supraventricular and ventricular tachyarrhythmias.
