Overnight sleeping induced daily repetitive left ventricular systolic and diastolic dysfunction in obstructive sleep apnoea: quantitative assessment using tissue Doppler imaging

摘要

Aims Although left ventricular (LV) diastolic dysfunction is frequently observed in patients with obstructive sleep apnoea (OSA), the effects of overnight sleeping on LV function remain unclear. The aim of this study was to determine acute effects of overnight sleeping on LV function in OSA patients.
