Effect of Remote Ischemic Preconditioning on Electrophysiological and Biomolecular Parameters in Non-valvular Paroxysmal Atrial Fibrillation: RIPPAF Study (RIPPAF)

August 17, 2017 updated by: Jedrzej Kosiuk

The aim of the study is to examine the effect of RIPC on physiological parameters in non-valvular paroxysmal atrial fibrillation. Furthermore the study will provide a unique bio-date base for further analysis of molecular and genetic mechanisms responsible for observed results.

The potential effect of RIPC on AF inducibility and/or prothrombotic activity might be implemented as additional treatment component to reduce AF burden and minimize thromboembolic risk.

Interim Analysis will be done after 73 patients.

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: RIPC-Group
After randomization patients will undergo 3 sessions of RIPC (Remote ischemic preconditioning) intervention: I) on preoperative day, II) 1 h before and III) directly before the blood sample collection and invasive measurement of electrophysiological parameters.
RIPC will be induced by the application of 3 short episodes (5 minutes) of forearm ischemia by cuff sphygmomanometer inflation separated by 5 minutes of reperfusion.
Placebo Comparator: Control-Group
After randomization patients will undergo 3 sessions of sham-intervention: I) on preoperative day, II) 1 h before and III) directly before the blood sample collection and invasive measurement of electrophysiological parameters.
In the control group the cuff will be inflated for 3 times at 10 mm Hg for 5 minutes with 5-minute intervals
