Figure 2 Experimental Protocol
Hemodynamic data, echocardiographic measurements, and sonomicrometry were recorded during control and ischemic conditions, at rest, and during dobutamine infusion. Stabilization periods of 15 min was defined for dobutamine stress measurements and 30 min after the end of the dobutamine infusion to return to resting condition. Dob = dobutamine; FLS 25% = flow-liming stenosis with 25% reduction in LAD resting flow; H = hemodynamic measurements; LAD = left anterior descending coronary artery mean; NFLS 40% = nonflow-limiting stenosis with 40% reduction in LAD hyperemic flow.
