cardiomegaly <\/a>is not a disease, it\u2019s usually a sign of an underlying cardiovascular disorder. Doctors test for the presence of cardiomegaly, using chest x-rays or MRI scans to complete a diagnosis. This disorder can occur due to a variety of conditions and is not always a permanent condition. <\/span><\/p>\n\n\n\nPregnant women can develop cardiomegaly, due to the increased need for circulation to supply the fetus with oxygenated blood during the pregnancy. An expectant mother typically experiences a reduction in symptoms shortly after giving birth. Cardiomegaly can place pressure on the lungs as it expands in the chest cavity, leading to shortness of breath. <\/span><\/p>\n\n\n\nHowever, in some cases, cardiomegaly can be a sign of coronary artery disease or heart valve problems, where the heart expands to deal with the loss of capacity. Specific disorders and diseases cause the heart chambers to thicken and dilate, enlarging the heart. Doctors treat cardiomegaly using medications, or in advanced cases, surgery.<\/span><\/p>\n\n\n\n\n\n\n\n\r\n<\/div>
