title: High Stroke Volume Variation Is an Independent Predictor for Decreased Blood Pressure During Hemodialysis.
abstract: It currently remains unclear whether stroke volume variation (SVV) before hemodialysis (HD) is an independent predictor of decreased blood pressure (BP) during HD. Fifty-two patients were divided into two groups (Decreased BP during HD group: N = 10, Non-decreased BP group: N = 42). Fractional shortening was lower, and mean arterial pressure (MAP) and SVV were higher in the Decreased BP during HD group. A multiple logistic regression analysis identified low fractional shortening, high MAP, and high SVV as independent predictors of decreased BP during HD. The areas under the ROC curves were as follows: 0.849 for MAP, 0.712 for SVV, and 0.893 for MAP and SVV. Optimal threshold values were 93.0 mm Hg for MAP and 17.3 % for SVV. A multivariate regression analysis identified anemia and a longer dialysis vintage as independently related factors for higher SVV. Our results suggest that high SVV is an independent predictor for decreased BP during HD.
