  1. Data are mean ± SD. Group legends in hypothermia series: controls subjected to 180-min ischemia and 120-min reperfusion (CON-22), cardioplegia with modified Krebs-Henseleit buffer-based cardioplegic solution (mKHB-22), cardioplegia with St Thomas’ Hospital cardioplegic solution №2 (STH2-22). Group legends in normothermia series: controls subjected to 60-min ischemia and 120-min reperfusion (CON-37), cardioplegia with modified Krebs-Henseleit buffer-based cardioplegic solution (mKHB-37), cardioplegia with St Thomas’ Hospital cardioplegic solution №2 (STH2-37).
  2. “-” - persistent ventricular fibrillation/asystole in all hearts.
