Pulmonary Edema Cases Higher Among Community Athletes

Recent findings published in the Journal of the Royal Society of Medicine reveals that extreme fitness commonly seen in athletes can sometimes be unexpectedly deadly.

"Swimming-induced pulmonary edema is a well-documented but relatively rare condition that may be misdiagnosed," said British cardiologist and lead study author, Dr. David MacIver, in a news release. "If an accurate diagnosis and appropriate advice are not given individuals are at increased risk of future life threatening episodes and drowning."

For the study, researchers examined statistics that showed increasing numbers of swimming-induced pulmonary edema cases in community triathletes and army trainees. Furthermore, findings revealed that the condition was more likely to develop in highly fit individuals undertaking strenuous or competitive swims, particularly in cold water.

Researchers also found that highly trained individuals were more susceptible to swimming-induced pulmonary edema as they likely experienced a mismatch in the ventricles' stroke volume as the heart beats, with results in excess accumulation of fluid in the lungs.

"If the athlete is in open water and unable or unwilling to rest while there is ongoing stroke volume difference, pulmonary edema can take place with potentially fatal consequences."

Fortunately, researchers said they believe that an increased awareness of this risk can help swimming-induced pulmonary edema, particularly among those dealing with the health issue.
