Exercise-induced pulmonary hemorrhage (EIPH) occurs commonly in horses undergoing strenuous exercise. Reported risk factors include racing in cold temperatures and wearing of bar shoes. In horses with documented moderate to severe EIPH, increasing the interval between races and adopting a negative race pace strategy may reduce the severity of EIPH in subsequent races. EIPH seems to have an impact on performance only when moderate to severe. This occurs in a small number of starters, approximately 6%. EIPH often is erratic in severity from race to race, although across a population it is weakly progressive over increasing race starts.

Background: RV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).

Objectives: To investigate the value of exercise challenge testing (ECT) in the diagnosis of cough variant asthma (CVA) in children.
Methods: A prospective study was conducted on 78 children with chronic cough who were admitted between January 2023 and January 2024. ECT was performed, and clinical data were collected.

Unlabelled: Exercise-induced pulmonary arterial hypertension (EiPH) is often treated with off-label use of pulmonary arterial hypertension-targeted therapy (PH-targeted therapy). Most measures of PAH severity are normal in patients with EiPH, posing challenges in evaluating for physiological improvement in patients treated for EiPH. In this study, we used non-invasive cardiopulmonary exercise testing (CPET) to assess for objective improvement in patients treated for EiPH.

Exercise intolerance is a hallmark symptom in adults with repaired tetralogy of Fallot (TOF). This may be attributed to the disease-related impairment in RV systolic function, augmentation in right ventricular (RV) load, and their combined effect on altering left ventricular (LV) hemodynamics. To further elucidate these mechanisms, we examined oxygen uptake (VO) by indirect-calorimetry and cardiac hemodynamics by echocardiography in 34 TOF (48 ± 14 yrs) and 29 healthy controls (41 ± 15 yrs), at rest and during exercise.

Background: The prognostic factors in mild fibrosing interstitial lung disease (FILD) have not been established.
Methods: We retrospectively attempted to identify predictive factors of annual progression in mild FILD with gender-age-physiology (GAP) score of 3 or less using logistic regression analysis. Annual FILD progression was defined as meeting any two or more of the following conditions: 1, more than 10% decrease in forced vital capacity (FVC) or 15% decrease in diffusing capacity of the lungs for carbon monoxide (D); 2, worsening of dyspnea; 3, worsening of fibrotic change on CT at 1 year after admission.
