Cor Pulmonale is pulmonary heart disease, which causes failure of the right ventricle. This comes as a result of high blood pressure within the lungs. Pulmonary edema is fluid accumulation in the lungs, often as a result of congestive heart failure. Both diseases would be unfortunate and difficult to deal with, but pulmonary edema would be preferable. There are medications and treatments that can be used in order to reduce the fluid in the lungs and keep the congestive heart failure at bay. The Cor Pulmonale, though, will damage the heart's right ventricle, and there is nothing that can be done to restore function to it.
