Effect of acute changes in aortic pressure on the coronary reserve.
The aim was to evaluate the effect of acute changes in aortic pressure on the coronary reserve and hyperaemic response. ⋯ The results suggest that coronary reserve increases during intra-aortic balloon pumping and decreases during aortic regurgitation; these changes could be attributed to the effect of the pressure changes on the hyperaemic flow.
