Dilated cardiomyopathy is diagnosed after excluding conditions such as hyperthyroidism, hypertension, coronary heart disease, cardiac hypertrophy, or myocarditis as underlying causes. Generally, the exact cause of dilated cardiomyopathy is unknown, rendering causal treatment impossible. Once diagnosed with dilated cardiomyopathy, it is impossible to completely cure the condition. The only approach is to manage symptoms and prevent further progression of the disease. Typically, this involves the use of beta-blockers, ACE inhibitors, and diuretics. If the patient has severe cardiac dysfunction, drugs like digoxin, which strengthen heart function, may be considered. If medication does not adequately control the condition, other treatments like CRT might be considered, as well as the use of phosphodiesterase inhibitors, diuretics, or intravenous cardiotonic glycosides.
