Cardiomyopathy refers to heart muscle disorders, in which the heart becomes enlarged, thick or rigid. As the disease develops, the patient’s heart becomes weaker and can’t pump blood through the body effectively and keep a normal electrical rhythm. Possible results are arrhythmias and heart failure. Dilated cardiomyopathy Dilated cardiomyopathy (DCM) is the most common type of the disease which mostly occurs in adults. It affects ventricles and atria respectively. DCM starts in the left ventricle with dilation of the heart muscle. The inside of the left ventricle is enlarged and the condition gradually spreads to the right ventricle and then the atria. With dilated chamber(s), the heart muscle can’t contract normally, causing arrhythmias, blood clots, heart valve problems and heart failure. Hypertrophic cardiomyopathy Hypertrophic cardiomyopathy (HCM) is a very common type of the disease that can affect people at any age. In HCM, heart muscle cells enlarge, leading to a thicker wall of the ventricle (usually the left ventricle) while its size stays the same. This can block the outflow of blood in the left ventricle. Symptoms such as chest pain, shortness of breath, dizziness, or fainting can appear in this condition.   Keywords: dilated hypertrophic cardiomyopathy     Related FAQs: http://healthtopquestions.com/?p=4639   http://healthtopquestions.com/?p=4425
