The Impact of Sleep-disordered Breathing on the Incidence of Postoperative Acute Kidney Injury in Patients Undergoing Valvular Heart Surgery

2019-09-12 02:34:42 | BioPortfolio


Sleep-disordered breathing has a prevalence of 30~80% in patients with heart diseases. Various studies have revealed a correlation between the incidence and various diseases such as heart failure, hypertension, diabetes, and cerebral infarction. Postoperative acute kidney injury after heart surgery is one of the major complications with incidence with 40~50%, however, there has been no preventive method or treatment yet. Recently, several studies have been published that have shown a correlation between sleep-disordered breathing and renal impairment. In general, sleep-disordered breathing can be regulated easily with continues positive expiratory pressure, which means that early diagnosis and treatment of sleep-disordered breathing might help to reduce the incidence of postoperative acute kidney injury and improve patients' prognosis.

In this study, the investigators investigate the impact of sleep-disordered breathing (diagnosed by oxygen desaturation index ≥15) on the incidence of postoperative acute kidney injury in patients undergoing valvular heart surgery.

Medical and Biotech [MESH] Definitions

Cardiac manifestation of systemic rheumatological conditions, such as RHEUMATIC FEVER. Rheumatic heart disease can involve any part the heart, most often the HEART VALVES and the ENDOCARDIUM.

Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).

Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144.

The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.

Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
