Myocardial preconditioning using adenosine: review and clinical experience

Abstract

Adenosine is an endogenous nucleotide and a breakdown product of adenosine triphosphate. Adenosine has been proposed as a mediator of the ischaemic preconditioning phenomenon. Ischaemic reperfusion injury incurred during and following cardiopulmonary bypass contributes to depressed myocardial function after cardiac surgery. It is believed that administering adenosine via the aortic root, immediately following aortic crossclamping as well as just prior to removal of the aortic crossclamp, provides myocardial preconditioning resulting in improved cardiac protection during ischaemic arrest and retarding ischaemic reperfusion injury. A retrospective analysis was done utilizing consecutive patients undergoing coronary artery bypass grafting performed by the same surgeon. Some of the patients received myocardial preconditioning with adenosine. A comparison was made in postoperative cardiac function between patients who underwent myocardial preconditioning and those who did not receive adenosine. Results demonstrate a greater improvement in postoperative cardiac function, when compared to preoperative values, in those patients receiving myocardial preconditioning with adenosine.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
