myocardial protection
Strategies used during cardiac surgery to prevent heart muscle damage during ischemia.
Full Definition
Myocardial protection encompasses the various techniques and strategies used during cardiac surgery to minimize myocardial injury while the heart is stopped for surgical repair. This includes the use of cardioplegia solutions (blood or crystalloid), hypothermia, and topical cooling to reduce metabolic demand and preserve cellular function. Adequate myocardial protection is critical for post-operative cardiac function and patient outcomes, and documentation should include the type of cardioplegia used, temperatures achieved, and any complications.
Usage
Usage note: Broader term than cardioplegia, which is one method of myocardial protection.
