Association of Presystolic Wave with Subclinical Left Ventricular Dysfunction in Obstructive Sleep Apnea Syndrome
Obstructive sleep apnea syndrome (OSAS) is associated with subclinical myocardial dysfunction. This study aimed to evaluate the association between presystolic wave (PSW) and left ventricular global longitudinal strain (GLS) in patients with confirmed OSAS and to determine whether PSW may serve as a simple echocardiogr...
