研究概览
简要总结
The overall goal is to evaluate the predictive accuracy of a measure of autoregulatory adequacy derived from CVInsight and compare it with other measures in recognizing hypotensive events during hemodialysis..
详细描述
Specific Aims are as follows:
- Assess the accuracy of a new rule set for CVInsight® in predicting intradialytic hypotensive episodes.
- Assess the comparative predictive accuracy of CVInsight® to other measures with regard to intradialytic hypotensive events.
- Assess estimated dry weight goals by monitoring post-dialytic vascular refill using CVInsight® and other measures.
- Assess hemodialysis(HD)-induced myocardial injury by monitoring the occurrence and frequency of arrhythmias and the levels of cardiac Troponin T.

入选标准
- •Eligibility shall consist of the following:
- •Age ≥ 20 years old
- •Speaks and understands English, Spanish or Chinese
- •Provides Informed Consent
- •Patients with 20% intradialytic hypotensive events over the last two months.
- •Exclusion criteria for both groups:
- •Unstable hemodialysis patients per judgment of the clinician prior to the start of the treatment
- •Patients unable to have blood pressure cuff measured on the upper arm
- •Inability to wear monitor on forehead
- •Patients treated with sodium or ultrafiltration profiling and the patient's nephrologist is unwilling to alter this for the study treatments
- •Patients unwilling to shave the anterior chest
- •Patients with active infection of the upper chest wall tissue.
- •Patients with a deep brain stimulator, as it may disrupt the quality of the ECG data.

结局指标
主要结局
Number of intradialytic hypotensive (IDH) episodes that can be detected by the new rule set for CVInsight.
时间窗: 3-4 hours, for two hemodialysis session, or 6-8 hours total
IDH defined by at least one of the following: 1) Symptoms of hypotension: dizziness, cramping, altered consciousness, nausea +/- vomiting (new since beginning of session), chest pain, shortness of breath, seizure, diaphoretic. 2) Intervention administered due to IDH; relevant interventions:a) a reduction in ultrafiltration (UF) goal programmed at start of treatment (tx); b) admin. of IV fluid, e.g. saline, mannitol or hypertonic saline; c) stopping tx early due to IDH symptoms or event. 3) A significant drop in blood pressure, regardless of symptoms, defined as: * For pts w/ a pre-dialysis systolic blood pressure (SBP) \>110 mm Hg, an intra or post-dialysis SBP \<90 mm Hg, or a drop of \>40 mm Hg over 30 min. * For pts w/ a pre-dialysis SBP \<110, a decline in SBP \<85 mm Hg or 15 mm Hg or lower than their starting BP.
次要结局
- Amount of post-dialytic vascular refill as separately indicated by both CVInsight® and CRIT-LINE III.(At the end of each dialysis session after the ultrafiltration rate (UFR) has turned off.)
- The comparative, predictive accuracy of CVInsight® and CRIT-LINE III with regard to intradialytic hypotensive events.(3-4 hours, for two hemodialysis session, or 6-8 hours total)
- The occurrence and frequency of arrhythmias as indicated on the Zio ECG Patch and the levels of cardiac Troponin T, taken prior to each HD treatment. which are indicative HD-induced myocardial injury..(24 hours before first session of monitored dialysis to at least 24 hours after the second session on monitored dialysis sessions.)
