All patients in the present study had been diagnosed with hypertension before, and treated with at least one or more antihypertensive agents. Despite aggressive treatment, BP control was considered to be inadequate by the K/DOQI guideline. The 12th annual report of the UK Renal Registry

(UKRR) indicated that 43.1% of HD patients achieve predialytic BP of <140/90 mmHg [13]. Strict control of BPs is often difficult, considering FK866 concentration the prevention of hypotension during HD. Davenport et al. [14] reported that intradialytic hypotension was significantly greater in centers that achieved better postdialysis BP targeting. The present data showed that predialysis systolic BPs were not correlated with any home BPs. Agarwal et al. [15] reported that BPs obtained before and after dialysis, even if obtained using standardized methods, agree poorly with selleck inhibitor interdialytic ambulatory BP. In contrast, home BP served as

a useful predictor of hypertension diagnosed by ambulatory BP monitoring. The difference between HD and non-HD morning MK5108 manufacturer BPs was weakly correlated with % interdialytic BW gain. This is reasonable because BPs in HD patients, in part, usually depend on an increase in fluid volume between dialysis. The present study demonstrated that LVMI had a significant positive correlation on univariate analysis with home BP, especially morning systolic BPs on HD and non-HD days. In contrast, predialysis BP did not correlate with LVMI. Multivariate analysis including several factors which could affect LVMI demonstrated that only morning systolic BPs on HD 4��8C and non-HD days were regarded as independent explanatory factors. LVMI has been reported as a critical indicator to predict mortality and CV outcomes in patients undergoing dialysis [16–19]. LVH regression in patients with ESRD has been shown to have a favorable and independent effect on patients’ all-cause and CV survival [20]. Agarwal et al. [10] reported that dialysis unit BPs in 140 HD patients were weak

correlates of LVH. On the other hand, systolic BPs outside the dialysis unit (1-week averaged home BP readings) were a stronger correlate of LVH. Diastolic BPs, regardless of the measurement technique, were of little use in detecting LVH. A more recent study reported that weekly averaged BP (WAB) was a useful marker that reflects BP variability during 1 week and correlates with target organ damage such as LVMI and brachial-ankle pulse wave velocity (PWV) [21]. Furthermore, systolic and diastolic WAB are almost completely consistent with BPs taken immediately after waking up on the next day after the middle dialysis session. The present data agree with these previous studies. It should be emphasized that home BPs, especially morning systolic BPs on HD days, play a pivotal role predicting LVMI. This phenomenon is considered to be reasonable because morning BPs on HD days can partly represent maximum volume overload to vasculature, thus affecting LVMI.
