Coronary Artery Bypass Graft CABG

Frailty is a major predictor of adverse outcomes following coronary artery bypass grafting (CABG), being associated with increased postoperative complications, prolonged hospitalization, delayed functional recovery, and reduced quality of life. Although minimally invasive coronary surgery (MICS) through left minithoracotomy has been associated with reduced surgical trauma and faster recovery in selected patients, its benefits have not been evaluated in a randomized trial specifically involving frail patients. The MINI FRAGILE trial is a prospective, multicenter, randomized, open-label clinical trial designed to compare minimally invasive CABG performed through left anterior minithoracotomy with conventional median sternotomy in patients aged 60 years or older with pre-frailty or frailty undergoing surgical coronary revascularization. Eligible participants will be randomized in a 1:1 ratio to either surgical approach. The primary objective is to determine whether minimally invasive CABG improves functional recovery, assessed by the change in the physical component of the SF-36 Health Survey 30 days after surgery. Secondary outcomes include major adverse cardiovascular events, mortality, intensive care unit and hospital length of stay, duration of mechanical ventilation, return to usual activities, surgical site infection, perioperative complications, postoperative pain, readmission, and adherence to enhanced recovery measures. The results of this trial are expected to provide high-quality evidence regarding the optimal surgical approach for frail patients requiring coronary artery bypass grafting.

This randomized, double-blind clinical trial aims to evaluate the impact of photobiomodulation therapy on postoperative outcomes in patients undergoing coronary artery bypass grafting (CABG). The study will compare two techniques for saphenous vein graft harvesting: the conventional technique and the no-touch technique. Participants will be randomly allocated into four groups: conventional harvesting with placebo, conventional harvesting with photobiomodulation, no-touch harvesting with placebo, and no-touch harvesting with photobiomodulation. The primary objective is to evaluate the effects of photobiomodulation on wound healing and postoperative complications related to the saphenous vein harvesting site. Secondary outcomes include clinical outcomes and functional capacity after surgery. The results may contribute to improving postoperative recovery and optimizing surgical strategies in patients undergoing myocardial revascularization.

Background: After heart surgery, patients require temporary chest tubes - plastic drains placed inside the chest to prevent fluid building up around the heart and lungs. These tubes are often very painful and can limit breathing, coughing, and movement, which necessitates usage of painkiller medication (opioids and non-steroidal anti-inflammatory drugs (NSAIDs)) that have negative side effects and can prolong hospital recovery. Despite this common problem, routine care lacks simple, add-on strategies that directly numb pain at the chest tube sites rather than relying solely on whole-body painkiller medicine. Purpose: To determine whether injecting a long-acting numbing medicine (bupivacaine 0.5%) through chest tubes safely reduces pain and lowers opioid and NSAID use compared with placebo. Objective: With ethics approval, data access, and study procedures already in place before May, the specific objective for this studentship is to collect and analyze data to evaluate the short-term effect of bupivacaine versus placebo on: * Mean pain scores from initial recovery to chest tube removal * Total mean opioid and NSAID use Methods: This single-centre, 1:1 block randomized, double-blind, placebo-controlled trial will enroll 60 adults undergoing coronary artery bypass (procedure to bypass blocked blood vessels supplying heart muscle using healthy blood vessels) at the Foothills Medical Centre. Patients receive either 10 mL bupivacaine 0.5% or normal saline (saltwater placebo) through chest tubes by heart surgeons whenever pain hits ≥3/10 using the Numeric Rating Scale (0 = no pain; 10 = most intense pain), from initial recovery to chest tube removal. Standard pain care will continue for all patients. The study team will record pain scores, opioid and NSAID doses, and any side effects for each group. Interval pain reduction will be measured 30, 60, 120 and 240 minutes post injection. Mean pain reduction and total painkiller use will be compared between the two groups.

Postoperative pain following coronary artery bypass grafting (CABG) via median sternotomy remains a significant clinical problem and is associated with increased opioid consumption and postoperative complications. Fascial plane blocks have emerged as part of multimodal analgesia strategies in cardiac surgery. This prospective, randomized, controlled, single-blinded study aims to evaluate the effect of an induction-time multimodal fascial plane block package-consisting of bilateral superficial parasternal block, bilateral serratus anterior plane block, and adductor canal block-on postoperative analgesia, opioid consumption, and clinical outcomes in patients undergoing elective isolated CABG with saphenous vein graft harvesting. Patients will be randomized in a 1:1 ratio to receive either the multimodal fascial plane block package in addition to standard postoperative analgesia or standard postoperative analgesia alone. The primary outcome is total opioid consumption within the first 24 postoperative hours. Secondary outcomes include pain scores, time to first opioid requirement, extubation time, postoperative pulmonary complications, atrial fibrillation, and length of ICU and hospital stay.

To explore surgical strategies that reduce perioperative neurologic complications in cardiovascular surgery, with the aim of improving perioperative outcomes and quality of life while reducing the socioeconomic burden. Specifically: This multicenter, randomized controlled clinical trial will evaluate the benefits of a novel aortic no-touch technique in reducing perioperative silent brain infarction(SBI) among patients undergoing surgical treatment for coronary artery disease. The findings are expected to provide a safe and effective myocardial revascularization strategy for individuals at high risk of cerebral ischemia.

This prospective, non-blinded, single-center, translational research study aims to validate a multimodal advanced imaging exam for cardiac viability. The protocol utilizes three distinct imaging modalities: Single Photon Emission Computed Tomography Myocardial Perfusion Imaging (SPECT MPI), 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and Hyperpolarized Carbon-13 (HP-13C) Pyruvate Magnetic Resonance Imaging (MRI). Under this protocol, the SPECT MPI and FDG-PET exams will be used in combination to comprehensively assess myocardial viability. Concurrently, the HP-13C Pyruvate MRI will be utilized to provide additional insights into myocardial metabolism. The study will evaluate healthy volunteers to establish baseline parameters and patients with ischemic cardiomyopathy (ICM) before and after surgical revascularization.

This study will be conducted to compare between incentive spirometry verses inspiratory muscle training preoperatively on (ABG) after coronary artery bypass graft surgery. Is there any significant difference of preoperative incentive spirometry verses inspiratory muscle training on Arterial blood gases (ABG) after coronary artery bypass graft surgery? Participants will: Group A (incentive spirometry group ) Group B (Inspiratory muscle trainer group ) for 5 days before operative Group C (control group) and group a , b will have routinely postoperative

The Saudi CABG Audit and Registry (SCAR) is a prospective, multicenter national clinical quality registry designed to systematically collect perioperative and long-term outcome data for all patients undergoing coronary artery bypass grafting (CABG) in Saudi Arabia. The registry will begin with a pilot phase in selected tertiary cardiac centers and will progressively expand to national coverage. SCAR captures detailed information on patient demographics, cardiac status, operative techniques, postoperative outcomes, and 1-year follow-up, including patient-reported quality-of-life measures (EQ-5D and SF-36). The aim is to establish a standardized national platform for benchmarking, quality improvement, and real-world evidence generation to support clinical decision-making and health policy development in cardiac surgery. Data are collected prospectively through secure electronic systems, anonymized before central storage, and analyzed using standardized definitions aligned with international registries such as STS and E-CABG.

The basic concept of prehabilitation is to increase the functional capacity of the individual to withstand an expected injury. It embodies the idea of being proactive against the common reactive approach of rehabilitation. While the initial prehabilitation model was limited to physical training, it has now evolved into a multimodal entity that includes nutritional optimisation, psychosocial preparation and smoking cessation in addition to exercise programmes. In the last decade, there has been an increasing effort to coincide prehabilitation with surgery, as surgery is rightly perceived as a stressor for human structural and physiological functions.

A review of the literature suggests that high-intensity intermittent inspiratory muscle training (IMT) combined with the Otago exercise program may provide positive effects on early post-discharge recovery of patients aged 65 years and older undergoing coronary artery bypass graft (CABG) surgery. No studies have yet examined the effects of high-intensity intermittent IMT combined with the Otago exercise program on patients undergoing CABG surgery. This study is the first to evaluate the effects of high-intensity intermittent IMT combined with the Otago exercise program on pulmonary function, functional capacity, muscle strength, functional mobility, balance, anxiety and depression levels, frailty, and quality of life in elderly patients undergoing CABG surgery.
