Right ventricular dysfunction in patients with obstructive sleep apnoea syndrome.
There is conclusive evidence that obstructive sleep apnoea syndrome (OSAS) influences right heart haemodynamics and can also induce pulmonary hypertension. It is not known, however, whether right ventricular dysfunction can occur in patients with OSAS in the absence of lung disease. We studied 107 patients (94 males, 13 females, mean age 55 +/- 11 yrs) with polysomnographically verified OSAS in...
متن کاملVentilatory control in patients with sleep apnoea and left ventricular dysfunction: comparison of obstructive and central sleep apnoea.
Sleep apnoea is common in patients with heart failure. While most patients have central sleep apnoea (CSA), a minority have obstructive sleep apnoea (OSA). The pathophysiology of CSA is not well understood. We hypothesized that central chemosensitivity would be an important pathophysiological factor in patients with CSA, and not in OSA. The aim of this study was to compare ventilatory responses...
متن کاملCerebral metabolic impairment in patients with obstructive sleep apnoea: an independent association of obstructive sleep apnoea with white matter change.
OBJECTIVES To determine the relation between severity of obstructive sleep apnoea (OSA) and degree of cerebral metabolic impairment. METHODS Fifty five patients with habitual snoring and excessive daytime sleepiness underwent standard overnight polysomnography and magnetic resonance spectroscopy separately. Proton MR spectra were measured with two dimensional chemical shift imaging (repetitio...
متن کاملControl of breathing in hypercapnic patients with obstructive sleep apnoea.
We read with great interest the article by LIN [1] recently published in the Journal. The author described six patients with pure obstructive sleep apnoea (OSA), initially presenting with hypercapnia, which was resolved after 2 weeks of continuous positive airway pressure (CPAP) treatment. It is well-known that hypercapnia is more frequent in patients with OSA and co-existing chronic obstructiv...
متن کاملObstructive sleep apnoea inhibits the recovery of left ventricular function in patients with acute myocardial infarction.
AIMS It has been suggested that obstructive sleep apnoea syndrome (OSA) may be a direct cause of left ventricular (LV) systolic dysfunction. This study was designed to examine our hypothesis that OSA inhibits the recovery of LV function in patients with acute myocardial infarction (AMI). METHODS AND RESULTS Our 86 consecutive first-AMI patients underwent primary percutaneous coronary interven...
