From the present review, it may be concluded that myocardial ischemia results in far more complicated syndromes than previously realized. Although not all aspects of the issues discussed in this review are currently a clinical reality in the daily practice of cardiovascular anesthesiologists, the understanding and application of these concepts are growing rapidly. Indications for revascularization procedures will be adjusted in patients with evidence of hibernating myocardium. In the future, postoperative myocardial dysfunction may be diminished by the prevention of myocardial stunning, for instance by altering the composition of the cardioplegic solution and other interventions. Finally, additional advances may involve reduction of the extent of perioperative myocardial infarctions by application of ischemic preconditioning.

D006348 Cardiac Surgical Procedures Surgery performed on the heart. Cardiac Surgical Procedure,Heart Surgical Procedure,Heart Surgical Procedures,Procedure, Cardiac Surgical,Procedure, Heart Surgical,Procedures, Cardiac Surgical,Procedures, Heart Surgical,Surgical Procedure, Cardiac,Surgical Procedure, Heart,Surgical Procedures, Cardiac,Surgical Procedures, Heart
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000787 Angina Pectoris The symptom of paroxysmal pain consequent to MYOCARDIAL ISCHEMIA usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the MYOCARDIUM exceed that supplied by the CORONARY CIRCULATION. Angor Pectoris,Stenocardia,Stenocardias
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001145 Arrhythmias, Cardiac Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction. Arrhythmia,Arrythmia,Cardiac Arrhythmia,Cardiac Arrhythmias,Cardiac Dysrhythmia,Arrhythmia, Cardiac,Dysrhythmia, Cardiac
D015428 Myocardial Reperfusion Injury Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm. Reperfusion Injury, Myocardial,Injury, Myocardial Reperfusion,Myocardial Ischemic Reperfusion Injury,Injuries, Myocardial Reperfusion,Myocardial Reperfusion Injuries,Reperfusion Injuries, Myocardial
D015906 Angioplasty, Balloon, Coronary Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply. Angioplasty, Coronary Balloon,Angioplasty, Transluminal, Percutaneous Coronary,Coronary Angioplasty, Transluminal Balloon,Percutaneous Transluminal Coronary Angioplasty,Balloon Dilation, Coronary Artery,Transluminal Coronary Balloon Dilation,Angioplasties, Coronary Balloon,Balloon Angioplasties, Coronary,Balloon Angioplasty, Coronary,Coronary Balloon Angioplasties,Coronary Balloon Angioplasty
D017682 Myocardial Stunning Prolonged dysfunction of the myocardium after a brief episode of severe ischemia, with gradual return of contractile activity. Hibernation, Myocardial,Myocardial Hibernation,Stunned Myocardium,Myocardium, Stunned,Stunning, Myocardial
D019157 Ischemic Preconditioning, Myocardial Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ISCHEMIA or REPERFUSION. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes.
