2. Fig 1
Baseline (preischemic) concentrations of important metabolites in the normal right ventricle (hatched bars) compared with the hypertrophic left ventricle (open bars). Mean ± standard error. *p less than 0.05 compared with right ventricular biopsy. (ADP = adenosine diphosphate; Ala = alanine; AMP = adenosine monophosphate; ATP = adenosine triphosphate; Glu = glutamate.)

3. Fig 2
Concentrations (nmol/mg protein) of myocardial metabolites in ventricular biopsies from left and right ventricles of patients in the antegrade group, collected before ischemia (solid bars) and after reperfusion (open bars). Mean ± standard error *p less than 0.05 compared with corresponding value in control biopsy. (Ala/Glu = alanine-glutamate ratio; ATP = adenosine triphosphate.)

4. Fig 3
Concentrations (nmol/mg protein) of myocardial metabolites in ventricular biopsies from left and right ventricles of patients in the retrograde group, collected before ischemia (solid bars) and after reperfusion (open bars). Mean ± standard error *p less than 0.05 compared with corresponding value in control biopsy. **p less than 0.05 versus control and left ventricle. (Ala/Glu = alanine-glutamate ratio; ATP = adenosine triphosphate.)
