Brief Summary:
Patients with end-stage renal disease (ESRD) are at significantly higher risk for death due to cardiovascular disease. Those with paradoxical increases in blood pressure (BP) during hemodialysis (HD), defined as intradialytic hypertension (IDH), are at even greater risk of cardiovascular mortality. This study seeks to determine the mechanisms that underlie IDH, and whether mindfulness meditation might improve BP during dialysis in these patients. The investigators will first determine if increased adrenaline levels during volume removal contributes to IDH. The investigators will then determine lack of suppression of adrenaline levels in the setting of a high BP also contributes to IDH. This will be done by manipulating blood pressure by using small amounts of vasoactive drugs, and determining if an appropriate response in adrenaline levels occurs. Lastly, the investigators will determine if an intradialytic mindfulness meditation program improves BP and adrenaline levels in ESRD patients with IDH.

Arms and Interventions

Arm Intervention/treatment
Experimental: Mindfulness Meditation
After individual instruction, participants in this arm will perform meditation by following a series of MM recordings during hemodialysis for the next 4 to 8 weeks.The MM instructor will also meet with the participants weekly to provide continued instruction. Participants will also be encouraged to perform MM using the MP3 player at home on non-dialysis days, and asked to keep a log of these sessions.
 Other: Mindfulness Meditation
Placebo Comparator: Health Education
Participants randomized to the control condition will undergo a 4 to 8 week health education series, with a parallel protocol as the MBSR intervention. Monitoring of adherence will be same as above.
 Other: Health Education
