HRT ups BP; risk of hypertension higher with longer duration of use

Penrith, Australia – A large new study of over 40,000 postmenopausal women has found that use of hormone replacement therapy (HRT) is associated with an increased risk of high blood pressure. The results also show, for the first time, that the risk of hypertension rises with longer duration of HRT use, say Dr Christine L Chiu (University of Western Sydney, Penrith, Australia) and colleagues in PLoS One.

And importantly, “the association between using HRT and high blood pressure was more prominent for younger postmenopausal women, aged 45-55 years,” senior author Dr Joanne M Lind (University of Western Sydney) told heartwire.

“By the time women reached their 70s, the impact was not significant anymore.”

We recommend that doctors take into consideration the fact that HRT could increase the odds of having high BP and if possible minimize the length of time that women take it.

Lind notes that it is “still only an association, we don’t know the direct cause. But we do know that of the women who’d used HRT, more of them had high BP compared with the women who’d never used it. We recommend that doctors take into consideration the fact that HRT could increase the odds of having high BP and if possible minimize the length of time that women take it.” She and her fellow authors also recommend that BP should be closely monitored both during and after use of hormone therapy, and that women be made aware that hypertension is a possible risk of HRT use.Source: www.theheart.org
