Remote Ischemic Preconditioning in ad Hoc Percutaneous Coronary

Status Completed

Clinical Trial Summary

Elective percutaneous coronary intervention (PCI) is associated with troponin release in approximately one third of cases. Myocardial necrosis may result from downstream embolization of atheromatous material, coronary side-branch occlusion and may involve ischemia/reperfusion injury. The investigators hypothesized that a single remote ischemic preconditioning cycle would reduce peri-procedural troponin release.

Clinical Trial Description

Elective percutaneous coronary intervention (PCI) is associated with troponin release in approximately one third of cases, which is a sensitive and specific marker of myocyte necrosis. Myocardial necrosis may result from downstream embolization of atheromatous material, coronary side-branch occlusion and may involve ischemia/reperfusion injury. A number of studies have demonstrated that procedure-related troponin release is associated with subsequent cardiovascular events and a worst prognosis, especially in those patients with the most marked elevation in troponin concentration.

Recently, 3 cycles of 5-minute ischemia followed by 5-minute reperfusion of the upper extremities were shown to reduce troponin release in elective PCI. However, this ischemic preconditioning (IPC) protocol requires 30 minutes and is of limited use in the context of PCI at the time of initial cardiac catheterization (ad hoc coronary intervention).

Since experimental evidence suggests that IPC is a graded than an "all-or-nothing" phenomenon, and even a short, single IPC cycle may have protective effects in the myocardium, the investigators hypothesized that patients undergoing ad hoc coronary intervention would have reduced peri-procedural troponin release if subjected to a single, remote IPC cycle, between diagnostic catheterization and coronary intervention. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
