Filter by:This study aimed to compare the efficacy of isolated coronary artery bypass grafting and coronary artery bypass grafting + mitral valve repair in moderate ischemic mitral regurgitation patients through a cohort and explore the potential risk factors of the clinical outcomes.
The goal of this clinical trial is to assess the effect of walking exercise on functional capacity and productivity in patients after Coronary Artery Bypass Graft who have completed phase II cardiac rehabilitation. The main question it aims to answer are: 1. What is the effect of walking exercise on functional capacity and productivity in patients after Coronary Artery Bypass Graft? Participants performed the exercise on the day agreed upon with the researcher. Respondents did walking exercises 3 times per week for 4 weeks with a duration of 10 minutes of warm-up, 30 minutes of walking exercises, and 10 minutes of cooling down. Respondents also did leg straightening every day for 4 weeks with a frequency of 1 time a day for 10 minutes. Researchers compared between intervention and control group to see if the effect between respondents who did walking and leg straightening exercises and also respondents who only did leg straightening.
Review the data of patients who underwent coronary artery bypass grafting (CABG) at the Department of Cardiovascular Surgery in Ruijin hospital from March 2020 to May 2022, including medical history, head and neck CTA, head CT scan, and early postoperative (within 7 days after surgery) neurological complications (defined as a composite of stroke, delayed awakening and severe delirium) . Case-control and retrospective cohorts were built to explore risk factors of early postoperative neurological complications, And its association with baseline carotid-cerebral vascular disease. Describe the epidemiological data of early postoperative neurological complications (stroke, delayed awakening, and severe delirium) after CABG surgery (within 7 days after surgery); explore independent risk factors of compound neurological complications, build predictive models; compare the effects of carotid-cerebral artery disease on early postoperative compound neurological complications.
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.
Up to 15% of operations in cardio-pulmonary by-pass are complicated by excessive postoperative blood loss, which negatively affects the outcomes. Recently, it has been demonstrated that fibrin clot susceptibility to lysis is a modulator of postoperative blood loss after cardiac surgery for aortic stenosis. Earlier, a preliminary study showed a negative association of postoperative blood loss after coronary artery by-pass grafting (CABG) with fibrin clot lysis time, reflecting susceptibility to fibrinolysis. In CABG, postoperative blood loss may depend on the operative technique with respect to left internal mammary artery (LIMA) harvesting. LIMA is taken down in virtually all CABG procedures, but harvesting technical details remain at surgeons discretion (skeletonization without opening the pleural cavity vs. pedicled graft with pleura wide open). The investigators decided to test the hypothesis that fibrin clot properties modulate the postoperative drainage following CABG strongly enough to attenuate the influence of surgical technique by randomizing the patients undergoing CABG with regard to LIMA harvesting technique.
This prospective randomized study elucidates the effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit for cardioprotection against ischemia-reperfusion injury during coronary artery bypass graft surgery with cardiopulmonary bypass.
Glyceryl trinitrate is used in coronary artery bypass grafting surgery. This surgery frequently employs hypothermic cardiopulmonary bypass, where the whole body is cooled down to 28-32 °C to arrest the heart, and protect the organs from ischemic insult. When the cardiac repair or grafting is done, the body is warmed to 37 °C. During this "rewarming period", the heart has to beat against the vessels, all of which are constricted due to hypothermia. To overcome this constriction of the vessels, and decrease the workload of the heart, glyceryl trinitrate is infused. This drug causes significant dilatation in arteries and veins, which allows the heart to pump the blood with less force. The dilatation of the vessels also allows the body to rewarm more easily. The investigators' concern is whether increased infusion rates of glyceryl trinitrate may cause uncontrolled rewarming of the brain or not. The investigators will measure the temperature of the brain using a temperature probe located in the nasal cavity. The temperature will be recorded at each minute during the the rewarming period. Results of two commonly used infusion rates of glyceryl trinitrate will be compared.
