First, you have to tell a little more detail of your mothers symptoms like breathlessness on exertion or at rest or on lying down that relieves on sitting up. In addition, any complaints of chest pain on exertion or at rest. Any past history of high BP or diabetes. Sometimes cough in a patient with heart enlargement is due to weakening of heart. So she should undergo an EKG and echocardiography for assessing the heart function. </s>
