Little evidence of cardiac involvement in Mild and Moderate Swimming- Induced Pulmonary Oedema (SIPE)

Abstract

Objectives: Swimming-induced pulmonary oedema (SIPE) is a potentially fatal condition associated with open-water swims. We sought to quantify the contribution of cardiac dysfunction to SIPE. Design: We aimed to assess the incidence of SIPE during an endurance cold water swim. We determined associations between SIPE and changes in cardiac function through a SIPE questionnaire, lung ultrasound (LUS), cardiac biomarkers (N-Terminal pro-B-type natriuretic peptide (NT proBNP) and cardiac troponin I (cTnI)) and transthoracic echocardiograms (TTE). Methods: Twenty open-water swimmers (10 males) underwent a TTE, LUS for pulmonary oedema and cardiac biomarkers before, 2-hours and 24-hours after an 8-..
