Values are mean ± SD.
ANOVA = analysis of variance; AWTd = left ventricular anterior wall thickness in diastole; AWTs = left ventricular anterior wall thickness in systole; C+D = caffeine + dobutamine; FS = left ventricular fractional shortening; LVIDd = left ventricular diameter in diastole; LVIDs = left ventricular diameter in systole; PWTd = left ventricular posterior wall thickness in diastole; PWTs = left ventricular posterior wall thickness in systole.
