Background:There is an increase of risk of coronary artery disease about 4-fold with diabetes
mellitus, and ischemic heart disease is liable for diabetes-related deaths. In this study, we
examined the association between glycemic control, as determined by Hemoglobin A1c, and the
incidence of periprocedural complications in diabetic patients who had coronary artery bypass
graft (CABG) undergoing percutaneous coronary intervention (PCI).
Aim of the study:To assess the effect of control of DM on the outcome of PCI in patients who
underwent CABG.

Background:Coronary artery disease is higher in risk with diabetes mellitus, and diabetesrelated
deaths can lead to ischemic heart disease. We examined the relationship between the
glycemic regulation as determined by Hemoglobin A1c and the occurrence of periprocedural
complications in patients who performed percutaneous coronary intervention (PCI) and had
Coronary artery Bypass Graft (CABG)
Objective: To identify associated complications and their sites with Percutaneous Coronary
Intervention in diabetic patientswho performed Coronary Artery Bypass Graft.
Methods:The cross-sectional analysis was performed at the cardiology department in Zagazig
University Hospital in which all 24 CABG & DM patients were included during the period
between January 2019 and January 2020 divided into 12 patients with controlled
DM(HbA1c>7)&12 patients with uncontrolled DM (HbA1c<7).Both patients had a complete
medical history, a detailed clinical evaluation, and preoperative laboratory work: role of the
renal, completion of blood counts as a marker for regulation of DM, ECG, and ECHO.
Glycosylated Hemoglobin HbA1c was used.

Background: Postoperative atrial fibrillation (POAF) is a common and potentially morbid
complication following cardiac surgery. It was reported to be associated with greater inhospital
mortality; prolonged hospital stays. In addition, the long-term survival was worse in
patients who developed POAF. Patients who develop POAF incur additional hospital
treatment cost and 2-to-4-fold increased risk of major adverse cardiac events.
Objective: To determine the possible predictors of POAF after coronary artery bypass
surgery and its impact on outcome.
Methods: Two hundred patients were enrolled; they were divided into 2 groups; Group I (n =
100 patients) developed POAF and group II (n = 100 patients) did not developed POAF. All
patients were subjected to history, examination, ECG, echocardiography, laboratory
investigation as CBC, coagulation profile, kidney function tests, liver enzymes and high
sensitivity troponin and coronary angiography to assess severity of coronary artery disease by
SYNTAX score.
Results: POAF score which contain 9 variables: Age >60 y, Smoking, COPD, CP bypass time
(min) >86.5, Vent. Time <23.5, PLR >113.4, LVEF <53.5, RV function by TAPSE <2.15 and
Syntax score >34.5. Each variable takes points according to multivariate analysis with total
score 20. ROC curve analysis was done to pick up the best cut off value of POAF Score and
incidence of POAF which revealed POAF Score more than 10 has sensitivity 99 % and
specificity 86% Area under the curve 0.99. Conclusion: POAF after CABG is associated with
higher morbidity and mortality, prolonged recumbence in the hospital. Prediction of POAF
might be useful in detection of patients at risk for these complications using POAF risk
score.
