Dilated cardiomyopathy generally refers to dilated cardiomyopathy, and even early dilated cardiomyopathy is usually not reversible. Dilated cardiomyopathy is generally irreversible. Patients cannot return to a normal state after their heart is enlarged and can only be treated aggressively to relieve symptoms and maintain normal heart function. Dilated cardiomyopathy has a poor prognosis, as patients can die from heart failure and severe arrhythmias, and some may experience sudden death. The treatment of dilated cardiomyopathy is aimed at stopping the underlying etiology-mediated myocardial damage, blocking the neurohumoral mechanisms that cause exacerbation of heart failure, removing the triggers for exacerbation of heart failure, controlling arrhythmias and preventing sudden death, preventing the development of various complications, such as thromboembolism, and improving clinical cardiac function, quality of life, and prolonging survival. Dilated heart disease need to be timely to the hospital to receive formal diagnosis and treatment.
