Hydrocortisone induced hypertrophic cardiomyopathy
International Journal of Cardiology
|January 5, 2010
Summary
Steroid administration in a preterm infant caused recurrent hypertrophic obstructive cardiomyopathy (HOCM). The condition resolved upon drug cessation, indicating a direct link between steroids and HOCM development in neonates.
Area of Science:
- Neonatal Medicine
- Pediatric Cardiology
- Pharmacology
Background:
- Broncho-pulmonary dysplasia is a common complication in preterm infants.
- Steroids are sometimes used to manage broncho-pulmonary dysplasia.
- Hypertrophic obstructive cardiomyopathy (HOCM) is a cardiac condition characterized by thickening of the heart muscle.
Observation:
- A preterm infant receiving hydrocortisone for broncho-pulmonary dysplasia developed HOCM.
- Echocardiography revealed left ventricular hypertrophy and outflow tract obstruction.
- The cardiac abnormalities resolved after discontinuing hydrocortisone.
Findings:
- Recurrent HOCM developed in the infant following a second course of hydrocortisone.
- This suggests a causal relationship between steroid administration and HOCM in this patient.
- The findings highlight a potential adverse effect of steroids in preterm neonates.
Implications:
- Steroid therapy in preterm infants may pose a risk for developing HOCM.
- Careful cardiac monitoring is warranted in neonates treated with steroids.
- Further research is needed to understand the mechanisms and prevalence of steroid-induced HOCM.

01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:29Cardiomyopathy V: Interprofessional Care
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
01:30Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
01:25Cardiomyopathy I: Introduction and Classification
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
01:29Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
