Even though not all findings have been equally positive, many retrospective studies seem to have shown an incremental survival improvement by increasing the number of arterial grafts. Multiple arterial (MultArt) grafting is only currently used in a small number of coronary arteries bypass grafting (CABG) surgeries, despite the convincing and comprehensive information in the published literature. The goal of the study is to compare the incidence of in-hospital mortality in patients following CABG with single versus multiple arterial grafts and to evaluate the frequency of single and multiple CABG arterial grafts in patients undergoing CABG for coronary arteries diseases (CAD). Following institutional review board permission, this descriptive case series was carried out at Jinnah Hospital's heart surgery department in Lahore. 250 patients receiving CABG under general anaesthesia were a part of this study. The quantity of arteries grafted was recorded during CABG. It was observed whether there were one or several arterial grafts. A single surgical team carried out every procedure, under general anaesthesia. Patients were moved to post-surgical wards after surgery. Following surgery, patients were monitored there for 7 days. In-hospital mortality is defined as when a patient dies while receiving treatment in the hospital. In this study, inpatient mortality affected 7 (or 5.9%) of patients treated with single grafts and just 1 (or 0.8%) of patients treated with multiple grafts (p=0.022). Patients who received single graft CABG had a considerably greater incidence of in-hospital mortality. The superiority of multiple arterial graft CABG in terms of lower hospital mortality rate was demonstrated by the study's findings.

To treat coronary artery disease, coronary artery bypass graft (CABG) surgery is done worldwide (CAD). Before harvesting the radial artery for cardiac bypass surgery, Allen's test is frequently used to evaluate the hand's ulnar collateral blood supply. Using Doppler Ultrasonography as a gold standard, this study was created to evaluate the diagnostic precision of Allen's test for the ulnar collateral flow of the donor limb before radial arteryharvesting. This cross-sectional study was conducted from January 2015 to September 2017 at the Jinnah Hospital in Lahore's Cardiac Surgery department. The consecutive sampling/non-probability method was employed. A signed consent form was obtained, and specific demographic data (name, age, and gender) was gathered. SPSS version 21 was used to enter and analyze all of the data. The patients in our study had a mean age of 50.91±9.13 years. The ratio of men to women was 1.3:1. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of Allen’s test was 77.05%, 81.36%, 81.03%, 77.42% & 79.17% taking Doppler test as gold standard. Allen's test, which uses Doppler ultrasonography as the gold standard, is a reliable and valid screening test for the ulnar collateral flow of the donor limb before radial artery harvesting, according to the findings of our study.

Preoperative use of aspirin in coronary artery bypass graft surgery (CABG) might rely more on surgeon’s preference rather than on evidence-based approach. Conflicting guidelines and lack of reliable recommendations make ambiguous the preoperative aspirin administration before elective CABG. This study was conducted to compare the outcome with or without aspirin in patients undergoing coronary artery bypass surgery. The aim of the study was to compare the outcome with or without aspirin in patients undergoing coronary artery bypass surgery. This Randomized controlled trial was conducted at the Department of Cardiac Surgery, AFIC/ NIHD, Rawalpindi from 11th Dec 2018 to 10th June 2019. One hundred and fifty patients fulfilling inclusion criteria underwent through CABG were divided into two groups. In group A, 75 patients continued aspirin, while in group B, aspirin was stopped 5 days before surgery. Patient’s demographic features, comorbid conditions, Postoperative bleeding, perioperative MI and need for blood transfusion were noted. The mean age and BMI of patients were 61.41 ± 3.09 and 63.96 ± 7.64 years and 28.98 ± 2.46 and 32.61 ± 1.98 Kg/m2 in group A and B, respectively. Male to female ratios were 3.41:1 and 4.35:1 in group A and B, respectively.  Diabetes and hypertension were seen in 67(89.34%) and 59(78.67%) patients and 69(90.67%) and 70(93.34%) patients in group A and B, respectively. Perioperative MI and blood transfusion were statistically significant among both groups (5.34% vs. 9.34% patients; p=0.0001 and 5.34% vs. 1.34%; p=0.0003). Mean postoperative bleeding was 401.39 ± 121.04 and 389.21 ± 101.13 ml/24 hr. in group A and B, respectively. The continuation of aspirin therapy in patients undergoing elective CABG reduces perioperative MI, increases quantity of postoperative bleeding and need for blood transfusion. There is a significant difference in outcome with or without aspirin in patients undergoing coronary artery bypass surgery.
