Exercise-induced pulmonary edema in the athlete, or couch potato?

摘要

The authors (1) discuss evidence for/against exercise-induced pulmonary edema in "human athletes." As noted by Hopkins (1), pulmonary artery wedge pressure (PAWP; said to reflect mean left-atrial pressure and pulmonary venous pressure) increases with exercise. Reeves and Taylor (3) have shown that 80% of the variance in pulmonary artery pressure (PAP) during exercise is explained by PAWP. In other words, the higher the PAWP, the higher the PAP (and the more likely to develop pulmonary edema).
