Suggests temporal dissociation between congestion and edema with acute LA pressure rise; leaves open clinical implications for human heart failure.
Does acute elevation of left atrial pressure >25 mmHg cause a time lag between pulmonary congestion and pulmonary edema in a canine model?
This study demonstrates a 30 to 60 minute time lag between acute left atrial pressure elevation causing pulmonary congestion and the subsequent development of pulmonary edema, explaining potential clinical discrepancies.
