Sleep Disordered Breathing in Acute Congestive Heart Failure
Impact of Sleep Disordered Breathing on Cardiac Injury in Acutely Decompensated Congestive Heart Failure
Study Overview
Status
Detailed Description
Consecutive patients admitted to the hospital with acutely decompensated heart failure will be identified for potential enrollment in this study. Enrolled patients will first be asked to complete questionnaires to assess their symptoms and risk of having sleep apnea.
Relevant information will be obtained from the electronic medical record (age, gender, body mass index, co-morbidities, medications, prior echocardiography results). Subjects will then undergo a "type III" portable monitoring sleep study on the first or second night of their hospital admission, which measures respiratory effort, nasal airflow, oxyhemoglobin saturation, and heart rate. Blood samples will be collected on the evening before (08:00 PM +/- 2 hours), and the morning after (06:00 AM +/-2 hours) sleep apnea testing. If not otherwise obtained clinically, echocardiography will be obtained within 48 hours of admission. After a period of medical management for acutely decompensated heart failure, subjects will then have a second portable sleep apnea study (with associated pre and post-sleep blood draws) on the evening prior to discharge (approximately hospital day 5 or 6). Later, clinical outcomes such as incidence of renal dysfunction, hospital length of stay etc. will be collected from the electronic medical record. Blood samples will be processed, stored, and subsequently analyzed for high-sensitivity cardiac troponin T and I.
