Not to be confused with hypertrophic cardiomyopathy or any other cardiomyopathy. Dilated cardiomyopathy or DCM is a condition in which the heart becomes enlarged and cannot pump blood efficiently. The decreased heart function can affect the lungs, liver, and other body systems. DCM is one of the cardiomyopathies, a group of diseases that affect primarily the myocardium (the muscle of the heart). Different cardiomyopathies have different causes and affect the heart in different ways. In DCM a portion of the myocardium is dilated, often without any obvious cause. Left or right ventricular systolic pump function of the heart is impaired, leading to progressive cardiac enlargement and hypertrophy, a process called ''remodeling''. Dilated cardiomyopathy is the most common form of non-ischemic cardiomyopathy. It occurs more frequently in men than in women, and is most common between the ages of 20 and 60 years. About one in three cases of congestive heart failure (CHF) is due to dilated cardiomyopathy.〔 Dilated cardiomyopathy also occurs in children. ==Signs and symptoms== (詳細はquality of life. A minority of people can experience significant symptoms. These might include: * Shortness of breath * Syncope * Angina, but only in the presence of ischemic heart disease A person suffering from dilated cardiomyopathy may have an enlarged heart, with pulmonary edema and an elevated jugular venous pressure and a low pulse pressure. Signs of mitral and tricuspid regurgitation may be present. A fast heart rate with no change during the respiratory cycle may also be found. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dilated cardiomyopathy」の詳細全文を読む スポンサード リンク
