NCT01466218
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
NCT01744210
Historically, transthoracic Doppler echocardiography has been unable to provide interpretable data of blood flow within the lung parenchyma because of air attenuation of Doppler signals. Recently, a transthoracic Doppler system known as the Sonara/tek Transcranial Doppler (TCD) System has been developed that can identify parenchymal pulmonary blood flow (PPBF) signals. The ability to non-invasively collect information regarding the pulmonary aspect of the cardio-pulmonary system may provide valuable information and new insights into the structural and functional characteristics of the lung parenchyma and vasculature in health and disease states.
NCT01272453
This is a prospective, controlled observational trial of patients undergoing clinically indicated cardiothoracic computed tomography (CT), including pulmonary or aortic angiography and coronary CT angiography (CCTA).
