Dilated cardiomyopathy (DCM) is a common cardiac diagnosis that may result as a consequence of a variety of pathologies. The differential diagnosis remains quite broad since many pathologies can present as DCM, and as a result the approach to diagnosis may, at times, be quite difficult. This review article discusses genetic and acquired causes of DCM, pathophysiology of myocardial damage, pathology, and diagnostic criteria. An approach to management is also included, in the hope of informing physicians of a clinical entity that afflicts a substantial number of people worldwide.
