Figure 1 Perioperative outcomes are complex traits, characteristically involving multiple gene-gene interactions and gene-environment interactions to produce a final clinical phenotype (presence/absence and severity of an adverse event). CPB = cardiopulmonary bypass; OR = operating room.

Figure 3 The degree of perioperative myocardial injury is a result of the balance between injurious and cardioprotective (endogenous and exogenous) biological mechanisms, mediated via a wide array of biochemical pathways with extensive genetic variability. AR = adrenergic receptor; CPB = cardiopulmonary bypass; EC = endothelial cells; PMN = polymorphonuclear neutrophils; RNS = reactive nitrogen species; ROS = reactive oxygen species.
