%X Immersion pulmonary edema (IPE) is a serious complication of water immersion during SCUBA diving. Myocardial ischemia can occur during IPE that worsened outcome. Because myocardial injury impacts the therapeutic management, we aim to evaluate the profile of cardiac markers (creatine phosphokinase (CPK), BNP, troponin T (TnT-hs) and troponin I (TnI-us) of divers with IPE. 12 male SCUBA divers admitted for suspected IPE were included. The collection of blood samples was performed at hospital entrance (T0) and 6 hours later (T0+6 hours). Diagnosis was confirmed by echocardiography or computed-tomography-scan. Mean±SD BNP (pg/mL) was 348± 324 at T0 and 223±177 at T0+6 hours (p<0.01), while mean CPK (IU), and mean TnT-hs (pg/mL) increased in the same times 238±200 vs 545±39, (p=0.008) and 128±42vs269±210, (p=0.01) respectively; no significant change was observed concerning TnI-us (pg/mL):110±34vs330±77, p=0.12. At T0+6 hours, 3 patients had high TnI-us while 6 patients had high TnT-hs. Mean CPK was correlated with TnT-hs but not with TnI-us. Coronary angiographies were normal. The increase in TnT during IPE may be secondary to the release of troponin from non-cardiac origin. The measurement of TnI in place of TnT permit in some cases to avoid additional examinations, especially unnecessary invasive investigations.<br><br>©2018 The Author(s).<p /> <p>Language: en</p>
