CABG

((82)) patients scheduled to undergo elective CABG by the same surgical team will be allocated randomly by computer-generated random numbers into two equal groups (n= 41). Study groups: Group S (Stellate Ganglion Block Group): Patients will receive an ultrasound-guided Left stellate ganglion block prior to induction of general anesthesia. The block will be performed at the C6 level under strict aseptic precautions using 5 mL of 0.25% bupivacaine. Successful blockade will be confirmed by the appearance of ipsilateral Horner's syndrome. Group C (Control Group): Patients will receive standard perioperative care without stellate ganglion block and will undergo the same anesthetic and surgical management protocol as Group S.

This study aims to determine whether starting respiratory physiotherapy one hour after removal of the breathing tube following elective coronary artery bypass graft (CABG) surgery leads to better recovery than the current standard approach, in which physiotherapy begins on the first postoperative day. The study will evaluate whether earlier physiotherapy improves lung function, reduces postoperative pulmonary complications, shortens intensive care unit and hospital stay, decreases pain and anxiety, and improves overall recovery after surgery. The main question is whether very early postoperative respiratory physiotherapy provides additional benefits for patients recovering from elective heart surgery compared with standard postoperative care.

The goal of this prospective, multicenter, randomized clinical trial is to learn whether a nonintubated supraglottic airway anesthesia strategy with early restoration of spontaneous breathing can reduce postoperative pulmonary complications and improve early recovery in adults undergoing elective cardiac surgery with cardiopulmonary bypass. The main questions it aims to answer are whether, compared with conventional endotracheal fast-track anesthesia, the nonintubated strategy can reduce pulmonary complications within 30 days after surgery, reduce the need for postoperative invasive mechanical ventilation and other respiratory support, and shorten the time spent in the intensive care unit. Participants will be randomly assigned to undergo cardiac surgery using either a standardized nonintubated supraglottic airway anesthesia strategy with early restoration of spontaneous breathing or a conventional endotracheal fast-track anesthesia strategy. Both groups will receive standardized perioperative care, with objective criteria for airway removal and readiness for discharge from the intensive care unit. Endotracheal intubation or escalation of respiratory and circulatory support will be performed whenever clinically necessary. Participants will be followed from screening through hospitalization, at 30 days after surgery, and for up to 1 year. Routine perioperative data and key postoperative outcomes, including pulmonary complications, respiratory support, intensive care unit stay, major organ complications, safety events, recovery, rehospitalization, and survival, will be collected.

Coronary artery bypass grafting (CABG) may be associated with prolonged recovery, particularly in high-risk patients. Although preoperative rehabilitation has shown promising results, evidence remains limited because of heterogeneous intervention protocols and variations in postoperative care. This study aims to investigate the effects of a structured inpatient physiotherapy program initiated at least two days before surgery and continued postoperatively, compared with the same structured physiotherapy program provided only during the postoperative period, in high-risk CABG patients. The primary outcome is hospital length of stay. Secondary outcomes include intensive care unit length of stay, C-reactive protein, neutrophil-to-lymphocyte ratio, hemoglobin, dyspnea, and fatigue.

Myocardial protection during surgical myocardial revascularization is crucial for reducing perioperative myocardial injury and improving postoperative outcomes. Blood cardioplegia represents the standard method in many centers, while del Nido cardioplegia, originally developed for the pediatric population, is increasingly being used in adult patients as well.

The primary goals of this study are to compare the differences in tissue-resident Treg gene signature for activation, proliferation, and suppressive function using single-cell/-nucleus RNA sequencing in patients treated with ld-IL-2 compared to control grouped by individual tissue beds from in and around the heart. Additionally, tissue-resident Tregs will be compared to peripheral blood Tregs from the same patient to assess the differential effect of ld-IL-2 on the two compartments.

The purpose of this study is to evaluate whether the application of soft foam dressings can reduce the occurrence of surgery-related pressure injuries among patients undergoing cardiac surgery. Specifically, this research aims to investigate differences in pressure injury outcomes before and after the intervention, and to assess the preventive effectiveness of soft foam dressings as an adjunctive skin-protection strategy.

Cardiovascular disease (CVD) remains the leading cause of death worldwide. Prevention of CAD by targeting modifiable factors remains a key public health priority. L-Ascorbic Acid (Vitamin C - Vit. C) and Omega 3 fatty acids, Eicosapentaenoic / Docosahexaenoic Acid (EPO/DHA), powerful but also necessary antioxidants for the human body, after observational studies as well as randomized studies seem to have a beneficial effect in the direction of the prevention of CVD with pleiotropic mechanisms. Lignin, a polymer of plant origin that is considered a dietary fiber, has a developed porous structure and can retain exogenous and endogenous toxins, and pathogenic microorganisms. Lactulose considered a prebiotic provides a selective substrate for the metabolism of saccharolytic bacteria with bifidogenic activity and multiple benefits to the host's gut health. Coronary artery bypass grafting (CABG) is an established surgical intervention and treatment of symptoms of myocardial ischemia that improves patient survival Optimal Medical Therapy (OMT) after coronary arterial bypass grafting (CABG) as described in current clinical practice could be made even better by the addition of these beneficial food supplements. A randomized controlled trial is proposed in an intervention group of 54 post-CABG patients who will be given daily orally in addition to the usual medication, 1000 mg Vitamin C, 840 mg EPO/DHA, 2130 mg Lignin \& 720 mg Lactulose and a control group of 54 patients (Control Group) in which only usual medication will be administered. The intervention will take place from the 15th postoperative day when CAGB patients are discharged and lasts for 2.5 months (10 weeks) postoperatively. The data will be collected on the 15th, 80-90th postop day in 6 months and 12 months postop and then the statistical analysis of the data will be performed. Considering the number of CABG surgeries performed electively in our clinic, this study is expected to be completed in approximately 2-3 years from the day of initiation. The expected knowledge through the expected results such as these will emerge from this study is the potentially beneficial effect of our food supplements administration (intervention), i.e. Vitamin C, EPO/DHA, Lignin \& Lactulose, on the postoperative course of our patients. Some degree of improvement in the well-being and clinical picture of our patients postoperatively is expected, which will be thoroughly investigated in each phase of the study.

This randomized multicenter trial compares coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) in 358 patients with ischemic left ventricular dysfunction and multivessel coronary disease. The study evaluates differences in survival, major cardiovascular events, and quality of life over 4 years, and contributes to the international STICH 3.0 collaboration assessing long-term outcomes.

This randomized controlled trial will compare the effectiveness of elliptical exercise training and Swiss ball exercise therapy in post-CABG patients. A total of 32 participants will be recruited through convenient sampling and randomly allocated into two groups (16 each). Group A will receive supervised elliptical exercise training, while Group B will perform Swiss ball exercises, with sessions conducted three times per week for 6-8 weeks. Outcomes including functional exercise capacity (Six-Minute Walk Test), resting heart rate (pulse oximetry), dyspnea (Modified Borg Scale), and quality of life (SF-36) will be assessed at baseline and post-intervention. Data will be analyzed using SPSS to determine the more effective rehabilitation approach for improving recovery after CABG.

Coronary artery disease (CAD) is a heart disease caused by the buildup of plaque inside the coronary arteries that restricts blood flow to the heart which leads to heart attack. If it involve more than one artery it will be more critical so the preferred treatment will be coronary artery bypass graft. Respiratory failure after Coronary Artery Bypass Grafting (CABG) is a serious complication with multifactorial causes i.e. pneumonia and atelectasis in inpatients. Postoperative pulmonary complications will be diagnosed using the Melbourne Group Scale (MGS), applied daily from postoperative day 1 to day 7. A score of ≥4 positive criteria will be used to identify PPCs. The scale's criteria will include chest radiograph findings, oxygen saturation, sputum characteristics, inflammatory markers, and ventilation data, physician diagnosis of pneumonia, readmission to ICU for respiratory reasons, prolong ventilation\> 24 hours, unplanned use of non-invasive ventilation.

This study aims to evaluate whether daily low-dose colchicine (0.5 mg), administered in addition to the standard secondary prevention regimen recommended in clinical guidelines after coronary artery bypass grafting (CABG), can further prevent graft failure after CABG through a prospective, randomized, double-blind, placebo-controlled clinical trial.

The purpose of this study is to learn more about a tool called Transit-Time Flow Measurement (TTFM). TTFM uses sound waves during surgery to check how well blood is flowing through blood vessels. This helps doctors see if the blood flow is good during coronary artery bypass grafting (CABG), which is a type of heart surgery

Neurocognitive decline has long been suspected to be a potential long-term complication of coronary artery bypass grafting surgery (CABG), with reports of post-operative cognitive dysfunction by objective testing approaching 15-50% of patients in the year following surgery. To determine the true rate of long-term cognitive dysfunction following CABG compared to percutaneous coronary intervention (PCI or coronary stent placement), we propose a multi-center, two-group, non-randomized study using computer-based customized neurocognitive testing (Cogsate), prior to the procedure and then at 30 days, 1-year and 2-years after revascularization to evaluate cognitive function vital for the maintenance and advancement of professional and personal activities. It is anticipated that the study will document a higher rate of cognitive dysfunction in the CABG group, that the landmark study will provide both the patient and physician with the information necessary to make an informed decision regarding the cognitive risks of CABG versus PCI when faced with the need for coronary revascularization, and that these results will change the clinical practice of recommending CABG as a primary revascularization option for those wishing to preserve cognitive function.

PROFILE-HF is a multicenter, observational, prospective study of the clinical course and outcomes of chronic heart failure (HF) and coronary artery disease (CAD) in patients undergoing coronary artery bypass grafting (CABG). The objective of the study is to develop a method for assessing the risk of adverse cardiovascular events in patients with CAD and HF who have undergone CABG, based on preoperative GDF-15 concentrations. The study will have a 12-month follow-up period; one in-person visit is planned at the end of the follow-up period. If it is not possible to visit a doctor in person, information will be collected through telephone contact with the patient or his relative or person caring for the patient.

Obesity has become a major public health problem in both developed and developing countries, with a continuous increase particularly since the 1980s. Moreover, it is a well-established metabolic risk factor for diabetes mellitus, hypertension, and various types of cancer, as well as cardiovascular diseases such as heart failure and coronary artery disease. Body mass index (BMI) is calculated by dividing body weight in kilograms by the square of height in meters and is widely used as an indicator of obesity. However, BMI does not quantitatively reflect body fat distribution and fails to account for components such as skeletal muscle and bone mass. Therefore, interest in assessing body fat distribution has increased, and in recent years, studies evaluating the correlation between anthropometric, biochemical, and anatomical measurements and clinical outcomes have become more frequent. In particular, it is acknowledged that abdominal obesity cannot be accurately represented by BMI alone and is primarily associated with visceral adipose tissue (VAT). The aim of this study is to evaluate the association between preoperative visceral and subcutaneous adipose tissue measurements (VAT and SAT), assessed by ultrasonography in patients scheduled for open-heart surgery, and the development of postoperative atrial fibrillation.

The goal of this clinical trial is to study postoperative analgesia in patients undergoing CABG. And learn if tafalgin (tyrosyl-D-arginyl-phenylalanyl-glycine amid) treats pain not inferiory then morphine. The main questions it aims to answer are: Does tafalgin (tyrosyl-D-arginyl-phenylalanyl-glycine amid) lower the VAS score same way as a morphine? What medical problems do participants have when taking tafalgin (tyrosyl-D-arginyl-phenylalanyl-glycine amid)? Participants will: Group (1)- subcutaneous single dose of morphine 10 mg would be administred based on VAS score \> 3 during 24 hours after CABG. Exprimental group (2)- subcutaneous single dose of tafalgin (tyrosyl-D-arginyl-phenylalanyl-glycine amid) - 0.4 mg would be administred based on VAS score \> 3 during 24 hours after CABG. Efficacy was assessed using the VAS scale decreassion. Hemodynamic parameters and arterial blood gases were also assessed.

The study aimed to assess the efficacy of customized pressure-guided elastic bandages (CPG-EB) in preventing postoperative edema and complications in Coronary Artery Bypass Graft (CABG) patients. While compression therapy, like compressive stockings, has benefits in preventing edema, concerns about affordability persist. CPG-EB provides optimal sub-bandage pressure, proven effective in venous leg ulcers. Implementing CPG-EB post-CABG could enhance venous blood flow, reducing complications and improving outcomes. Patients were divided into two groups: one with CPG-EB and the other standard post-CABG care. Data collected at 1, 2, and 6 weeks post-surgery assessed swelling and wound complications. Comparative analysis used standardized criteria.

The introduction of synthetic opioids in 1960 to general anesthesia together with sedative hypnotics and muscle relaxants allowed the appearance of the concept of multimodal balanced anesthesia. Although they help in achieving hemodynamic stability during anesthesia of open heart surgeries, their administration consequences are neither scarce nor benign to the patient. Perioperative opioids are associated with increased incidence of respiratory depression, prolonged mechanical ventilation, nausea and vomiting, prolonged sedation, Postoperative ileus (POI), urine retention, Postoperative cognitive dysfunction (POCD), immune depression and hyperalgesia (Beloeil et al., 2018). Coronary artery bypass graft surgery with cardiopulmonary bypass (CPB) is particularly vulnerable to the above-mentioned complications. Indeed, some of the side effects of this surgery overlap with the adverse effects of opioids. Postoperative pulmonary complications are observed in up to 50% of patients (Fisscher et al., 2022) and POCD or delirium in 4-54% according to studies (Bhushan et al., 2021). Whereas major gastrointestinal complications are estimated to occur in around 3% of patients, essentially acute pancreatitis, postoperative ileus (Marsoner et al., 2019). Opioid-free anesthesia (OFA) strategies have emerged to avoid intraoperative opioid use. It is based on the fact that a sympathetic reaction evidenced by hemodynamic changes in an anesthetised patient does not systematically reflect pain. In addition, a sleeping patient will not recall pain, while hormonal stress and sympathetic and inflammatory reactions can be controlled by therapeutic classes

It will be a randomized clinical trial with a sample size of 66. A convenient sampling technique will be used to recruit the CABG phase II patients for the study. Then, they will be divided into three groups by block randomization. Weight-bearing Liuzijue Qigong will be given as a baseline treatment to all groups. In group A, patients will engage in multimodal circuit training while simultaneously viewing the nature scenes through VR in a clinical setting, in group B, patients will be given multimodal circuit training in a clinical setting while in group C, patients will be given multimodal circuit training through telerehabilitation. The dyspnea 12 Questionnaire will be used for measuring dyspnea, Cooper's 12-minute test will be used to assess cardiorespiratory fitness, echocardiography will be used to assess Left ventricular ejection fraction, EQ-5D-5L will be used to assess quality of life, and Pittsburgh Sleep Quality Index (PSQI) will be used to assess the quality of sleep. Data will be entered and analyzed through SPSS version 21.

The goal of this pilot trial is to to evaluate the preliminary effect of oral colchicine therapy on graft outcomes in patients underwent primary isolated CABG. The main questions it aims to answer is: 1. Whether the oral colchicine therapy may reduce the failure outcome of grafts after CABG. 2. Whether it is feasible to construct a muticenter powered trial to test the superiority hypothesis. Researchers will compare colchicine to none to see if colchicine works. Participants will 1. Take oral colchicine (0.5mg daily) therapy for 12 months after CABG. 2. Clinical follow-up at Month 1, 6, and 12 after CABG. 3. Protocol-driven CCTA at Week 1 and Month 12 after CABG.

The goal of this clinical trial is to evaluate whether the CA330 cytokine adsorption column can reduce perioperative severe bleeding adverse events in patients receiving anticoagulant and/or antiplatelet therapy who undergo non-elective cardiac surgery with cardiopulmonary bypass. The main questions it aims to answer are: * Does the use of the CA330 cytokine adsorption column lower the incidence of perioperative severe bleeding compared with standard care? * Does the intervention improve short-term clinical outcomes, such as transfusion requirements, reoperation rates for bleeding, or overall postoperative recovery? If there is a comparison group: Researchers will compare patients treated with the CA330 cytokine adsorption column versus patients receiving standard cardiopulmonary bypass management to see if cytokine adsorption provides additional safety and efficacy benefits. Participants will: * Undergo non-elective cardiac surgery requiring cardiopulmonary bypass. * Be randomly assigned to receive either the CA330 cytokine adsorption column integrated into the CPB circuit (intervention arm) or standard CPB management without the device (control arm). * Be monitored for perioperative bleeding outcomes, transfusion needs, reoperation rates, and overall postoperative prognosis.

aims to compare the efficacy of the posterior pericardial window versus retro-cardiac drain in preventing postoperative atrial fibrillation and pericardial complications following CABG, while assessing their impact on hospital and ICU stay, pericardial effusions, re exploration for bleeding, post-operative blood transfusions, and mortality.

The goal of this study aims to investigate the use of artificial intelligence to analyze and evaluate the characteristics and proficiency of surgeons during vascular anastomosis in coronary artery bypass grafting (CABG) procedures. The main question it aims to answer is: Consistency assessment between AI evaluation scores and human expert evaluation scores for surgeons during left anterior descending (LAD) artery anastomosis.

The RECOVER study, titled Cardiac Rehabilitation Cohort at the Medicine Campus Davos for Exploration of Recovery, is a prospective, non-interventional, monocentric cohort study conducted at the Hochgebirgsklinik Davos. The study is sponsored by Medicine Campus Davos AG and the Kühne Foundation, with an estimated start date in July 2025 and planned completion by December 2034, with the possibility of extension. The principal investigator of the study is PD Dr. David Niederseer from Hochgebirgsklinik Davos, who also represents the study. The research team includes co-investigators such as Prof. Dr. Stefan Blankenberg and Prof. Dr. Andreas Ziegler from Cardio-CARE, Medicine Campus Davos, as well as Dr. Jan Vontobel from Hochgebirgsklinik Davos. The study will enroll patients referred to Hochgebirgsklinik Davos for cardiac rehabilitation who provide informed consent. Cardiac rehabilitation is an evidence-based therapy for patients with heart disease, including those who have undergone cardiac procedures or surgeries. The primary objectives are to evaluate baseline patient characteristics, rehabilitation strategies, predictors of recovery, and clinical outcomes during and after rehabilitation. To support this, a detailed database and biobank will be established to allow for comprehensive phenotyping, extensive clinical assessments, and long-term follow-up. RECOVER seeks to gain translational insights into how patient-specific factors - such as genetics, plasma, digital and clinical biomarkers, and comorbidities - influence long-term clinical outcomes. The goal is to identify modifiable risk factors to optimize individualized therapeutic approaches in cardiac rehabilitation.
