  Purpose

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.

Arms Assigned Interventions
Active Comparator: 1
Leg postconditioning
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).
Active Comparator: 2
Arm postconditioning
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).
Placebo Comparator: 3
Control group
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).
