The Effect of Peri-percutaneous Coronary Intervention Oxygenation on

Status Completed

Clinical Trial Summary

Elective percutaneous coronary intervention (PCI) is often associated with myocardial necrosis evidenced by peri-procedural troponin release. This is a surrogate for subsequent cardiovascular events. There is no study on the effect of peri-PCI oxygenation in in myocardial protection and cardiopulmonary fitness outcome. Patients with higher baseline cardiopulmonary fitness will have lower mortality.

This study is to assess the utility of oxygen to reduce ischaemia in patients with significant stable coronary artery disease scheduled for elective PCI. The secondary objective is to evaluate further effect of peri- PCI oxygenation on cardiovascular fitness and autonomic response.

Clinical Trial Description

OBJECTIVE: This study is to assess the utility of oxygen to reduce ischaemia in patients with significant stable coronary artery disease scheduled for elective PCI. The secondary objective is to evaluate further effect of peri- PCI oxygenation on cardiovascular fitness and autonomic response.

STUDY DESIGN: Randomized double blinded prospective pilot study SAMPLE SIZE: 30 patients scheduled for elective for PCI randomized to 2 groups, oxygen group ( 15L/min) and air group METHOD: Patient whom fulfil inclusion criteria were recruited and randomized to 2 groups via computer allocation system. The assigned inhaled gas will be delivered via high-flow mask at 15L/min for a minimum of 30 minutes immediately prior to and continued throughout the PCI procedure. Patients were blinded throughout the procedure but the practising cardiologist and staff nurses were not blinded. Routine care continued post PCI. Blood sampling for Troponin I was taken at 6 hours and 24 hours following stent implantation. Patients were discharged one day after the procedure as per current routine practice.

Patients were given routine follow up with the cardiac rehabilitation clinic in 4 weeks time post discharge. EST was arranged 6 weeks post procedure PRIMARY OUTCOME MEASURE: Troponin I at 6 and 24 hours SECONDARY OUTCOME MEASURE: METs, Heart Rate Recovery, Chronotropic Index ;

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.
