Inflammatory Biomarkers Predict Pulmonary Outcomes in Coronary Artery Bypass Grafting

Coronary Artery DiseaseChronic Obstructive Pulmonary Disease

The primary objective of this pilot study is to identify and quantify inflammatory and genetic markers from bronchoalveolar lavage fluid (BALF) and serum in patients with a history of chronic obstructive pulmonary disease (COPD) undergoing elective coronary revascularization (CABG) to determine the risk of developing post operative respiratory failure. To achieve this objective, this proposal outlines the following specific aims: Aim #1. To identify from BALF and serum, the change in inflammatory and genetic markers in patients with a history of COPD undergoing CABG. BALF and serum samples will be obtained at the time of intubation immediately prior to surgery and again upon skin closure immediately after the surgical procedure. Aim #2. To determine the extent to which inflammatory and/or genetic markers correlate with post-operative pulmonary complications defined as prolonged mechanical ventilation (> 24 hours), pneumonia, and/or tracheostomy. Aim #3. To inform the development and implementation of a large pivotal trial which may impact clinical decision-making during the initial pre-operative outpatient assessment of COPD patients undergoing CABG.

Pulmonary DiseaseChronic Obstructive

This is a 3 year longitudinal study to identify novel endpoints and compare these with standard measures such as forced expiratory volume in 1 second (FEV1) for their ability to measure and predict COPD (Chronic Obstructive Pulmonary Disease) severity and its progression over time. Control subjects (smokers and never smokers) will be recruited as comparators with the COPD subjects.

An Observational Study to Assess RSV-associated Illness in Adults With COPD and/or CHF

Respiratory Syncytial VirusChronic Obstructive Pulmonary Disease1 more

The primary objective of this observational study is to determine the incidence of medically attended (inpatient or outpatient) acute respiratory illnesses or events leading to worsening cardiorespiratory status (ie, acute exacerbations of chronic obstructive pulmonary disease [AECOPD] or worsening CHF) associated with RSV infections in high-risk adults (ie, those with severe COPD and/or advanced CHF) across multiple consecutive RSV seasons.
