is there an increase in ultrasound comets after intense exercise?
['Healthy athletes developed subclinical increase in pulmonary water content immediately after an Ironman race at sea level, as shown by the increased number of ULCs related to cardiac changes occurring during exercise.', 'Increased EVLW is associated with estimated PCWP and indices of left ventricular systolic and diastolic dysfunction. The additional exercise-induced increase of PCWP, the worsening of left ventricular diastolic function, and extensive wall-motion abnormalities correlate with variations of EVLW.', ' Among them chest ultrasonography can detect and quantify the extravascular lung water, creating "comet-tail" ultrasound artefacts (ULCs) from water-thickened pulmonary interlobular septa.', ' In top-level breath-hold divers, chest sonography frequently reveals an increased number of ULCs after immersion, indicating a relatively high prevalence of (often subclinical) reversible extravascular lung water accumulation.']
['Strenuous exercise and exercise perfomed in extreme conditions provoke increase in interstitial pulmonary water content as shown by the increased number of ultrasuond comets']
