2. Fig 1
Effects of (A) St. Thomas’ solution (St. T) and (B) pinacidil cardioplegia (PIN) on left ventricular (LV) myocardial contractility as assessed by preload-recruitable stroke work relationships (PRSW) before (PRE, solid line) and after (POST, broken line) ischemia. Results are expressed as the mean ± the standard error of the mean. (Lw = PRSW x-intercept; Mw = PRSW slope; r = correlation coefficient.)

3. Fig 2
Effects of (A) St. Thomas’ solution (St. T) and (B) pinacidil cardioplegia (PIN) on left ventricular end-diastolic pressure (LVEDP)–dimension relationships before (PRE) and after (POST) ischemia. Results are expressed as the mean ± the standard error of the mean. (α and β = nonlinear regression coefficients of exponential LVEDP–dimension relationship EDP = α × eβ × V [see Data Acquisition and Analysis section for details]; LV = left ventricular; r = correlation coefficient.)

4. Fig 3
Effect of St. Thomas’ solution (St. T) and pinacidil cardioplegia (PIN) on myocardial tissue water prior to ischemia (PRE), after 2 hours of ischemia (ISC) and after reperfusion (POST). Results are expressed as the mean ± the standard error of the mean. One-way repeated-measures analysis of variance was used.
