Abstract:
Objective To explore the relationship between obstructive sleep apnea syndrome(OSAS)and the left ventricular diastolic dysfunction.Methods 20 consecutive newly diagnosed middle-aged OSAS patients(OSAS group)with neither controllable factors nor conditions affecting left ventricular diastolic function and 15 healthy control subjects(control group)were examined with echocardiography.Results The OSAS group exhibited left ventricular diastolic dysfunction compared with the control group,including increase of isovolumic relaxation time(P<0.05)and mitral deceleration time(P<0.05),decrease of E/A.There was no difference between tow groups in interventricular systolic thickness,posterior wall thickness,left ventricular systolic diameter,left ventricular diastolic diameter and others.Conclusion OSAS may be related with the left ventricular diastolic dysfunction.
