Abstract
This prospective observational study was conducted in National Heart Institute of Egypt.
One hundred patients with multi-vessel CAD indicated for CABG were included in the study, and divided into two groups
group I: patients with no history of previous PCI.
group II: patients with history of PCI before CABG.
Patients with single vessel disease, combined CABG with other cardiac procedures, emergency CABG patients, and significant stenosis of carotid arteries with CABG were excluded from the study.
Preoperative coronary angiography (CA) for both groups was studied for number, and site of diseased vessels. Conventional general anaesthesia, standard median sternotomy, standard cardiopulmonary bypass, and antegrade warm blood cardioplegia were done in all patients.
There was statistical difference in age between the two groups, but Regarding sex distribution P value was not significant for, No statistical differences were found in any of the risk factors.
There was no statistical difference in all New York Heart Association (NYHA) class of dyspnea between the two groups. Regarding preoperative comorbidities they showed no statistical difference between both groups but Previous myocardial infarction (MI) were higher in group II.
Echocardiography showed no difference in mean end-systolic diameter (ESD), resting segmental wall motion abnormalities (RSWMA) or ejection fraction (EF) between the two groups, however mean end-diastolic diameter (EDD) was higher in group II.
