Abstract:
Objective To assess the left ventricular(LV)segmental function by velocity vector imaging(VVI)in uremic patients with diffferent quantity of parathyroid hormone(PTH).Methods Sixty patients with uremia were divided into 2 groups according to the value of PTH:group A with PTH less than 3 times of upper normal limit,group B with PTH more than 3 times of upper normal limit.Normal control group was 30 healthy subj ects.All people were evaluated by VVI.The parameters,including the longitudinal systolic strain rate(SSR),diastolic strain rate(DSR),were analysed among the three groups.Results Compared with normal group,in group A and B,SSR,DSR in all segments were lower.Compared with group A,in group B,DSR were all significantly lower(P＜0.05),SSR in apex of laternal wall,medium of anterior septum wall,posterior wall,medium and apex of posterior septum wall and superior wall,base,medium and apex of anterior wall were significantly lower(P＜0.05).There was no statistically significant difference of left ventricular ejection fraction between the two groups(P＞0.05).Conclusions VVI is a viable objective tool to quantitatively assess LV segmental function damaged by different quantity of PTH.
