Cardiac Remote Ischemic Preconditioning Before Elective Major Vascular Surgery (CRIPES)

This study is currently recruiting participants. (see Contacts and Locations)

  Purpose

Vascular surgery is considered a high-risk operation with an anticipated risk of major cardiovascular complications in excess of 5%. The occurrence of a cardiovascular complication after surgery carries a long-term higher mortality risk. The main objective of this investigation is to reduce the proportion of patients having major cardiovascular complications during surgery through a clinical protocol of remote preconditioning that is safe, effective and reproducible.

Primary Outcome Measures:
  • Troponin I elevation above the URL [ Time Frame: Within 1 week after surgery ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: July 2011
Estimated Study Completion Date: July 2015
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Control
Blood pressure cuff inflated in the right or left arm to 40-50 mmHg
Other: Control
A Blood Pressure cuff inflated to 40-50 mmHg
Active Comparator: Preconditioning
The RIPC protocol will consist of three cycles of the following: 5-minute inflation of a blood pressure cuff around the right upper arm to 200 mmHg (or 20 above the systolic blood pressure if baseline BP > 200 mmHg) to allow for external compression of the brachial artery resulting in transient arm ischemia, followed by a 5-minute interval of cuff deflation to allow for reperfusion. The total duration of the protocol is 30 minutes equally divided between ischemia and reperfusion. The protocol is to be applied in the patient room the morning of the operation.

Criteria

Inclusion Criteria:
