Prevalence of diabetes mellitus in patients undergoing coronary artery bypass grafting in a Tertiary Care Hospital.

Objective: To find out the prevalence of diabetes mellitus in patients undergoing coronary artery bypass grafting (CABG). Methods: This retrospective study was conducted in Northwest General Hospital and Research center Hayatabad, Peshawar over a duration of 15 months (December 2020 - March 2022). Every patient was tested through regular laboratory investigations. Diabetes mellitus was established according to WHO standards of fasting plasma glucose >126 mg/dl or two hours postprandial glucose level of 200 mg/dl. Data were analyzed using SPSS. Mean and standard deviation was used for quantitative data. Frequency and percentages were used for qualitative data. Shapiro Wilk's test was done to find the normality of the data. Results: Out of a total of 360 candidates, 129 (36%) individuals were non-diabetic and 231 (64%) candidates were diabetic. Among the diabetic patients, 64 (28%) were female and 167 (72%) were males with a ratio of 1:2.6 respectively. Conclusion: Prevalence of diabetes was 64% among the CABG population. Since the prevalence of diabetes can significantly affect the outcomes of people undergoing CABG, it is essential to generate awareness regarding diabetes among healthcare workers as well as the general population. More extensive research is needed to be carried by various health care centers to figure out the prevalence of diabetes mellitus in cardiac surgery patients.

Modifiable Risk Factors associated with Post-Operative Bleeding and transfusion requirements in Cardiac Surgery.

Objectives: In this study we determine the modifiable factors related to bleeding and transfusion in post-cardiac surgery patients who underwent open heart surgery. Methods: This is a retrospective study that include two hundred patients who had undergone open heart surgery (OHS) at Northwest General Hospital and Research Center from December 2018 to July 2021. Platelet count and hemoglobin level were measured in the pre-operative period. Results: This study included both male and female patients. Postoperative platelets were counted as follow: 50-100 x109 L in 3.0% cases, 101-150 x109 L seen in 27.5% cases, and >150 x 109 L in 69.5% cases which required transfusion. We have also reported the increased requirement of transfusion of blood and blood products in patients with pre-operative hemoglobin (Hb) < 10 g/dl. Conclusion: Correction of pre-op Hb, post-op platelet count and total bypass time are the significant and preventable parameters in patients undergoing cardiac surgery if proper pre-op assessment of the patient is performed.

Frequency of intra-aortic balloon pump insertion and associated factors in coronary artery bypass Grafting in a tertiary care hospital.

OBJECTIVE: To find the incidence of intra-aortic balloon pump (IABP) induction and factors associated with its insertion in coronary artery bypass grafting (CABG). METHODS: This retrospective observational non interventional study was conducted at Cardiac Surgery Department, North West General Hospital and Research Center, Peshawar from December 2018 to March 2020. The total sample size was 360 patients who underwent coronary artery bypass grafting (CABG). The research was piloted in the cardiac operation theatre then cardiac intensive care unit (CICU) of Northwest General Hospital and Research center Hayatabad Peshawar. Data was collected from 360 patients scheduled for CABG. Total numbers of patients in whom IABP was inserted and factors associated with IABP insertions were noted. All the information was collected on a specifically prepared Form. Data was entered and evaluated in statistical package for social sciences form 25. RESULTS: In this study, a total of 360 patients were observed who underwent coronary artery bypass grafting (CABG). We determined the frequency of IABP induction and the factors related to it. Gender distribution among patients who were assisted with IABP was 43% female and 57% male. IABP induction was done for most of moderately to severely reduced ejection fraction patients. Other factors related to patients who required IABP support were previous myocardial infarction 100%, hypertension 86%, diabetes mellitus 64%, coronary end-arterectomy 21% and smoking 7%. The results were analyzed. We have used the (SPSS) version 25 and Chi-square test for analysis in which the P-value less than 0.00001 is statistically significant. CONCLUSION: Incidence of insertion of IABP among CABG population was 3.9% in our hospital. It is an essential support to post CABG patient with left ventricular dysfunction after cardiopulmonary bypass with moderate to severely reduced ejection fraction, Myocardial infarction, hypertension, diabetes mellitus. Smoking and endarterectomy were not significantly related to IABP induction in our study. Multicenter study is still required to find out the other factors governing the IABP insertion.
