• Target enrollment: 0
• Participant gender: All

Summary

forty patients with age ranged between 40-70 years undergoing elective coronary artery bypass graft surgery with cardiopulmonary bypass will be included, they will divided into two groups.

Ozone Group: in which Ozone will be added to cold blood cardioplegia. Control Group: in which in which only cold blood cardioplegia

Primary outcome:

Pattern of recovery of myocardium after declamping of Aorta

1. Time of cardiac rhythm return after declamping.

2. type of cardiac rhythm after declamping and rate of DC use.

Secondary outcome:

A-cardiac parameters

• Incidence of post operative cardiac dysrhythmias

• postoperative ejection fraction (EF)

• Postoperative parameters of myocardial ischaemia

• a- Troponin levels
