Overview
Dilated cardiomyopathy (DCM) relates to a group of heterogeneous myocardial disorders and is characterized by dilatation and impaired contraction and systolic function of the left or both ventricles. Atrial and/or ventricular arrhythmias can occcur, and there is a risk for sudden death. [1] The weight of the heart is increased but the maximal thicknesses of the left ventricular free wall and septum are usually normal as a result of the abnormally dilated chambers.[2]
Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.[3]
- Life-threatening causes:
- Common causes:
- Idiopathic
- Myocarditis
- Ischemic heart disease
- Infiltrative disease
- Peripartum cardiomyopathy
- Hypertension
- Human immunodeficiency virus (HIV) infection
- Connective tissue disease
- Substance abuse
- Doxorubicin
- Other
