Filter by:Acute kidney injury is a frequent complication after coronary artery bypass grafting (CABG). Roxadustat is a prolyl hydroxylase inhibitor (PHI) which can stabilize hypoxia-inducible factor (HIF) and improve the hypoxic tolerance of tissues. Roxadustat has shown effect in reducing acute kidney injury in animal studies. This study aims to evaluate the efficacy of administration of Roxadustat before surgery in the prevention of acute kidney injury after CABG.
Inadequate pain control after coronary artery bypass graft surgery increases mortality and results in a higher incidence of persistent poststernotomy pain syndrome. Our aim is to assess whether ultrasound-guided parasternal intercostal block (PSIB) or surgeon implied transversus thoracic muscle plane block (TTMPB) would improve the postoperative pain scores and decrease tramadol consumption better after coronary artery bypass graft surgery
Coronary artery disease has the highest mortality rate worldwide and coronary artery bypass grafting (CABG) is the most common cardiac surgery performed in patients with coronary artery disease to revascularize the heart. Despite of improvement in operation techniques, cardioplegia, cardiopulmonary bypass (CPB), myocardial injury related to on-pump CABG is still prominent. In patient with low ejection fraction undergone on-pump CABG, myocardial injury is related to worse outcome and prognosis during peri-operative and post-operative period. On-pump CABG patients with low ejection fraction has increased (up to four times higher) post-operative in hospital mortality rate compared to patient with normal ejection fraction. Administration of intravenous glutamine had been documented in reducing myocardial damage during cardiac surgery and previous studies indicated that glutamine can protect against myocardial injury by various mechanism during ischemia and reperfusion. The purpose of this study to determine whether intravenous glutamine could prevent the decline of plasma glutamine level, reduce myocardial damage, improve hemodynamic profile, and reduce morbidity of on-pump CABG in patients with low ejection fraction.
More than 20,000 patients benefit from coronary bypass surgery in France each year. Median discharge without complication is eight days postoperatively, whereas by day four after surgery, hospitalization is only necessary for medical supervision of the occurrence of complications (scar infection, atrial fibrillation, pericardial effusion), waiting for a downstream bed in cardiac rehabilitation. Some studies have shown the feasibility of a return home from day 4 after CABG in the United States and England under some conditions of selection and monitoring of patients. However, there is currently no validated telemonitoring tool for patients in early postoperative coronary bypass surgery. In this pilot study, during hospitalization for early postoperative coronary bypass surgery, a combination of connected devices for the measurement of physiological parameters and for clinical self-evaluation by the patient will be evaluated. The results of this project will be used as a basis for a future larger study in which an early home discharge can be proposed to patients.
The study is a two-arm parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness and feasibility of using high-quality medication reminder smartphone application as a tool for secondary prevention in patients undergone CABG with DM, including the change in quality of life, medication adherence improvement and clinical outcome. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive information of secondary prevention of CHD and medication alarm using a specific smartphone application, while the control group will receive usual care.
Acute renal failure is a frequent and severe postoperative complication of cardiac surgery performed under extracorporeal circulation. It is an independent risk factor for mortality and significantly increases the length of hospital stay. The origin of renal insufficiency after extracorporeal circulation is multifactorial (long duration of extracorporeal circulation, hemodynamic instability per and post-extracorporeal circulation, prolonged hypotension, transfusion ...). Nevertheless, an entirely different pathophysiological mechanism, though not recent, is less often mentioned but shows renewed interest. This is the concept of renal venous congestion which may be responsible for impaired renal function in the absence of cardiac dysfunction. Based on Guyton's circulatory model, the investigators approach this systemic venous hypertension through the measurement of the Pmsf-PVC gradient.
Coronary artery disease is one of the biggest health issue worldwide.The treatment, in a large part of the patients, implicates a so called bypass-operation, that consists in to connect new vascular conduits (grafts) beyond the narrowed coronary vessels to improve the blood supply to the heart. One of the graft that is commonly used is the saphenous vein from the leg. The disadvantage of the saphenous vein graft is the predisposition to early obstruction. The international literature shows the following grades of occlusion: 15% in the first year and 40% after 10 year. At the Cardio-Thoracic Clinic of the University hospital of Örebro has been developed a new method to harvest the saphenous vein together with the surrounding fat-tissue. This technique, called no-touch technique, has the advantage to reduce the damages to the vein during the harvesting, showing a substantially reduced risk for future occlusion (5% after 18 months and 10% after 8,5 years). The aim of the PhD project is to evaluate the results of the no-touch technique in compare to the conventional technique for the venous graft harvesting. The focus of the study is to analyse all the operated patients in our clinic who underwent a post-operative coronary angiography do to angina pectoris (heart pain). All the patients who received a stent during the post-operative angiography will be analysed in detail and one will compare the occlusion grade and the rate of major adverse cardiac events (MACE). This study is the first and the only one in the world that will examine the long-term results of the no-touch technique in particular after the stenting of the venous graft.
The purpose of this study is to compare the efficacy and safety for 12- vs. 1-month of pantoprazole treatment in preventing dual antiplatelet therapy (DAPT)-related upper gastrointestinal mucosal injury after coronary artery bypass grafting (CABG). To date, there has been no study using esophagogastroduodenoscopy (EGD) to compare the differences in upper gastrointestinal mucosal injury (including reflux esophagitis) after 6 and 12 months of PPI treatment combined with two different DAPT regimens (clopidogrel plus aspirin or ticagrelor plus aspirin).
The primary objective of this study is to assess the performance of an in silico designed alternative protocol for control of stress hyperglycemia of inpatients treated for Coronary Artery Bypass Graft (CABG) or valve replacement surgery in the University of Virginia cardiothoracic ICU.
