Overview, Causes, & Risk Factors
Pulmonary edema is usually caused by heart failure that results in increased pressure in the pulmonary (lung) veins. However, problems within the lungs themselves can also result in fluid accumulation.
Pulmonary edema can be a complication of a heart attack, leaking or narrowed heart valves (mitral or aortic valves), or any disease of the heart that either results in weakening and/or stiffening of the heart muscle (cardiomyopathy). The failing heart transmits its increased pressure to the lung veins. As pressure in the lung veins rises, fluid is pushed into the air spaces (alveoli). This fluid then becomes a barrier to normal oxygen exchange, resulting in shortness of breath.
Pulmonary edema can also be caused by direct lung injury from toxins including heat and poisonous gas, severe infection, or an excess of body fluid as seen in kidney failure.
