U can have an enlarged heart after a heart attack. Enlarged heart can also be seen in dilated cardiomyopathy which is a weakness of heart muscle fibers. There are other causes of enlarged heart like fluid overload, pulmonary hypertension, high BP for a long time can also cause an enlarged heart, heart valves narrowing or leaking, kidney failure all can cause enlarged heart. My advice to you is to get a 2d echo which will give an idea about the cause of enlarged heart. Further course can be decided after 2 D echo findings. Thank you </s>
