Linear regression analysis identified the former two as independent predictors of QTVN. In conclusion, elevated repolarization lability is directly associated with sympathetic cardiac activation in patients with essential hypertension.]]> Sat 24 Mar 2018 08:16:04 AEDT ]]> Atrial shunt device for heart failure with preserved and mildly reduced ejection fraction (REDUCE LAP-HF II): a randomised, multicentre, blinded, sham-controlled trial https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47964 70 mm Hg associated with worse outcomes]), right atrial volume index (pinteraction=0·012 [≥29·7 mL/m2, worse outcomes]), and sex (pinteraction=0·02 [men, worse outcomes]). There were no differences in the composite safety endpoint between the two groups (n=116 [38%] for shunt device vs n=97 [31%] for sham procedure; p=0·11). Interpretation: Placement of an atrial shunt device did not reduce the total rate of heart failure events or improve health status in the overall population of patients with heart failure and ejection fraction of greater than or equal to 40%.
