Can a blood clot cause cor pulmonale?

Yes, a blood clot can cause cor pulmonale.

Cor pulmonale is a condition in which the right ventricle of the heart becomes enlarged and weakened due to increased pressure in the pulmonary artery. This can occur as a result of a blood clot in the pulmonary artery, known as a pulmonary embolism.

When a pulmonary embolism occurs, it blocks the flow of blood from the heart to the lungs. This can cause the pressure in the pulmonary artery to increase, which in turn puts a strain on the right ventricle of the heart. Over time, this can lead to the development of cor pulmonale.

Symptoms of cor pulmonale can include shortness of breath, fatigue, chest pain, and swelling in the legs and ankles. Treatment for cor pulmonale typically involves medications to reduce pressure in the pulmonary artery and improve heart function. In some cases, surgery may be necessary to remove the blood clot.
