Vocal Changes
Cor pulmonale may cause vocal changes. An individual might sound hoarse. The voice may be softer, quieter or at a lower pitch, and it can sound strained or raspy.
Hoarseness can arise as a cor pulmonale symptom if the pulmonary artery is stretched. When wider, this artery can put pressure on a nerve called the recurrent laryngeal nerve. This nerve is responsible for sending signals between the brain and the muscles of the larynx, or voice box.
