Remote Ischemic Postconditioning During Percutaneous Coronary Interventions
Overview
Angioplasty is a commonly performed procedure for treating blockage of the blood vessels in the heart. Although this procedure is usually successful, it is often accompanied by a small degree of damage to the heart (i.e., small heart attack). The purpose of this study is to find out if inflating a blood pressure cuff on the arm or the leg at the time of angioplasty for several minutes has a beneficial effect. Patients will be assigned to one of three treatment groups: inflating blood pressure cuff on the arm, inflating blood pressure cuff on the leg and a control group.
Full Title of Study: “Remote Ischemic Postconditioning During Percutaneous Coronary Interventions.”
Study Type
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Prevention
- Masking: Double (Care Provider, Outcomes Assessor)
- Study Primary Completion Date: June 2014
Interventions
- Procedure: remote ischemic postconditioning
- Three 5- minute cycles of blood pressure cuff inflation according to the assigned group. The cuff is inflated to 200 mm Hg (and at least 20 mmHg above the systolic blood pressure) for 5 minutes followed by a 5-minute deflation (reperfusion).
