[Cardiac protection is a clinical evidence].
OBJECTIVE
Anaesthetics may have protective effect against myocardial ischemia. We aimed to investigate if sevoflurane administration could exert myocardial protection during following coronary occlusion in patients with coronary artery disease.


METHODS
a).


METHODS
prospective, randomized study. b).


METHODS
University Hospital, cardiac surgical operative theatre. c).


METHODS
42 patients with coronary artery disease, scheduled to undergo coronary surgery.


METHODS
severe coronary stenosis of anterior descending coronary artery; no collateral flow on angiography; at least two normokinetic segments in the myocardial region supplied by the vessel being bypassed. PATIENTS were randomized to receive (group S) or not (group C) sevoflurane administration for 15 min just before coronary occlusion. d).


METHODS
Transoesophageal Tissue Doppler echocardiographic examination of myocardial systolic and early diastolic velocities in both groups basally and 60 s after coronary occlusion by the surgeon. e).


METHODS
systolic and early diastolic velocities were registered by Tissue Doppler from a long-axis view of the interventricular septum or the anterior wall of the left ventricle.


RESULTS
In group C a significant reduction of systolic and diastolic intramyocardial velocities was found during myocardial ischemia due to coronary occlusion.


CONCLUSIONS
Treatment with sevoflurane before coronary occlusion seem effective in reducing functional myocardial impairment due to ischemia.
