Abstract:
Objective To evaluate the clinical application of ultrasonic integrated backscatter(IBS) parameters and assess the lesion of myocardium in patients with different left ventricular geometric patterns.Methods Four groups were analyzed according to left ventricular mass index and relative wall thickness in 146 essential hypertensive patients,including group 1(n=64),group 2(n=18),group 3(n=20),group 4(n=44).Myocardial IBS,normalized IBS (IBS%),cyclic variation of IBS(CVIB) and transmural gradient of IBS(TGIB) of interventricular septum(IVS) and post wall(PW) were measured in 4 groups and 32 normal control subjects.Results Among the four groups,IBS% of IVS and PW were the highest in group 3 ( 53.6%? 9.8%, 52.8%? 8.3%,respectively) and next higher in group 2 ( 49.8%? 7.2%, 49.6%? 9.0%,respectively) and group 4 ( 49.0%? 7.7%, 48.9%? 8.2%,respectively),and was low in group 1 ( 42.3%? 8.4%, 41.8%? 9.1%,respectively) (P
