Dilated Cardiomyopathy (DCM)
CardiovascularCanineFelineNew
Key Points
  • Dilated cardiomyopathy (DCM) is a myocardial disease characterised by ventricular dilation and impaired systolic function, leading to reduced cardiac output
  • It’s most commonly seen in dogs
  • Typically asymptomatic until secondary CHF or arrhythmias develop
  • Echocardiography is the best tool for diagnosis
  • Pimobendan is used to delay the onset of CHF
    • Diuretics, ACE inhibitors and antiarrhythmics are added in later-stage disease
  • Taurine deficiencies are associated with development of secondary DCM, so feeding a complete diet is essential for cardiac health
Differential Diagnoses
  1. Myxomatous mitral valve disease (MMVD)
  2. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
  3. Pericardial effusion
  4. Heartworm disease
