Most likely not related to your heart, but you should ask a doctor to be safe. When just one limb like one arm or one leg is swelling, it's very unlikely to be related to your heart. Usually it's due to vascular insufficiencies or as stated above a lymphatic issue. Also, with arm pain, have you injured your arm? The vessels of the lymphatic system are very weak so any swelling can cause them to close off and fluid to back up.
