The Effect of GRAVITY on Physiological Measurements During Invasive Coronary Angiography and Intervention

NCT03097172 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 22

No results posted yet for this study

Summary

This is a single centre observational study on the impact of change in patient position and hence gravity, on physiological measurements in coronary arteries.

When patients present with heart attacks involving completely occluded heart arteries, there are signs anecdotally and in literature that arteries sitting higher up with the patient lying flat, receive less blood supply than arteries sitting lower down.

The investigators believe this effect is due to the pull of gravity on the flow of blood through the heart arteries. If this is indeed the case, changing position from lying supine (patient on their back) to lying prone (patient on their front) could reverse these anatomical positions and change measurements obtained during a coronary angiogram. These measurements include pressure and flow.
