Table 1 Hemodynamics. Compiled hemodynamic data across tested conditions (mean ± standard deviation; HR = heart rate, AoP = aortic blood pressure, LVEDP = left ventricular end-diastolic pressure, QLAD Peak = left anterior descending coronary artery peak Doppler blood flow rate, dP/dTmax, dP/dTmin = maxima and minima of LV pressure derivative with respect to time, RPP = rate pressure product). Symbols denote p < 0.05 via one-way ANOVA († versus baseline, ‡ versus mild stenosis, § versus mild stenosis + dobutamine, ¶ versus moderate stenosis)

From: Regional myocardial strain analysis via 2D speckle tracking echocardiography: validation with sonomicrometry and correlation with regional blood flow in the presence of graded coronary stenoses and dobutamine stress
