AbstractObjective:Toinvestigatethecorrelationbetweencarotidplaquestabilityassessedbyultrasoundandnocturalblood presure fluctuations inelderly patients with obstructive sleepapnea-hypopnea sydrome(OSAHS).Methods:Atotalof72elderlypatients withOSAHSwhowereadmitedtoJiangsuTaihuRehabilitation Hospital fromJuly2O23 toApril2O25 wereselectedas studyparticipants.Allpatientswerediagnosedbypolysomnography.According totheapnea-hypopnea index(AHI）,patints were divided into three groups : mild group( 5⩽AHI30,n=30 ). Carotid ultrasonographyand 24-hour ambulatory blood pressre monitoring were performed forallpatients to analyze thecorrelationbetweencarotid plaquestabilityandnocturalblood pressreflutuations.Results:WiththeincreaseofH,the microarousal index gradually increased among the three groups( P
