Observational Study of Sleep-disordered Breathing One Year After Lung Transplantation

What this Trial Is About

Sleep-disordered breathing (SDB) involves repeated pauses in breathing during sleep, leading to daytime tiredness and reduced quality of life. This research focuses on people who have received a lung transplant, as they often face chronic health problems and weight gain that may affect sleep. The study aims to understand how common SDB is after lung transplantation and to explore its types and links to heart and lung health, kidney function, and graft failure. Participants will undergo diagnostic polysomnography, a sleep study, one year after their lung transplant to detect SDB and determine its type, whether central or obstructive. Researchers will also assess heart function with echocardiography, lung function, blood tests, and 24-hour blood pressure monitoring at the same time to examine how SDB relates to these factors. During the study, participants will be monitored one year post-transplant with sleep tests and various health assessments. The main measurement is the number of participants with SDB and its type at that time. Secondary outcomes include heart and lung function and blood pressure. The study involves no treatment intervention and focuses on observation and data collection over this period.
