Lung and Heart Function Across Decades of Life in Health

This is an observational study to recruit and thoroughly characterize 200 age- and gender-matched healthy controls without a history of exposure to airborne hazards. The childhood health and disease profiles of participants will also be evaluated to provide assessment of their physical fitness as adolescents. The participants will undergo detailed clinical, physiological, and radiological evaluations that will match the PDCEN Core Clinical Evaluation, which includes administration of health, environmental and occupational exposures, respiratory, and physical fitness questionnaires, pulmonary function testing (PFT), forced oscillometry (FOT), cardiopulmonary exercise testing (CPET) with maximum effort, dynamic hyperinflation, and exercise-induced bronchospasm protocols, methacholine challenge testing, transthoracic echocardiography, and computer tomography (CT) of chest, as well as pulmonary and systemic biomarker analysis including fractional exhalation of nitric oxide (FeNO) and peripheral blood sampling for blood count and metabolic panel including liver and kidney function.
