Filter by:Abstract Anaesthetic support for cardiac surgery significantly influences the course of the intraoperative period and the success of the postoperative period. Total intravenous anaesthesia and inhalation anaesthesia are the traditional methods of anaesthesia in cardiac surgery. However, there are few studies assessing the effectiveness of surgical aggression protection in cardiac surgery. Objectives: To study the effectiveness of body protection against surgical aggression by TIVA and inhalational anaesthesia in cardiac surgery. Materials and methods. The examination and treatment data of 89 patients were included in the study. All patients underwent coronary artery bypass grafting, mitral valve replacement/plasty, aortic valve replacement cardiopulmonary bypass conditions. The patients were divided into 2 groups according to the type of disease: the first (1) group with coronary heart disease. The second (2) group with valvular heart disease. There were 65 patients in the first group and 22 in the second. Both groups were divided into 3 subgroups according to the type of anaesthesia: patients anaesthetised with propofol, with sevoflurane, with isoflurane.
Abstract Cardiac surgery in adults is associated with the occurrence of post-operative complications. Even minor complications can increase the cost of their treatment. Given the potentially preventable nature of a number of these postoperative complications, preventive methods should be used to improve outcomes after cardiac surgery. One of them, is the choice of anaesthetic technique. Objectives: To evaluate the effects of sevoflurane, isoflurane and propofol on blood oxygen transport function and body energy expenditure during cardiac surgery in adults. Materials and methods. A total of 90 patients were included in the study. All patients were divided into 3 groups: 1- (n=30) included patients who were anesthetized with propofol. The second group (n=30) consisted of patients who underwent sevoflurane inhalation anaesthesia. Group 3 (n=30) was treated with isoflurane. All patients underwent coronary artery bypass grafting under cardiopulmonary bypass.
Conventionally, long-axis in-plane (LA-IP), short-axis out-of-plane (SA-OOP) and dynamic needle tip positioning based on SA-OOP views are commonly used method to image the target vessel during cannulation under US guidance. A modified SA-OOP that add developing line on the ultrasonic probe improve the success rate of cannula insertion into the radial artery on the first attempt.
Background and aims: One of the investigated possible modulators of serum fetuin-A, associated with the risk of developing coronary artery disease (CAD), is omega-3 fatty acids (FAs). This study aims to evaluate the effects of omega-3 FA supplementation on serum fetuin-A concentration in patients with CAD. Methods: The study was carried out on 34 male volunteer patients aged 35-75 years, newly diagnosed with CAD by conventional coronary angiography. Patients with CAD were divided into the "Omega-3 Group (n:16)" and "Control Group (n:18)". Low-fat diet principles were explained to both groups at baseline. While 1.560 mg/day omega-3 FA supplementation was given to the patients in the omega-3 group for eight weeks, but not in the control group. Food intake was recorded using six-day food records.
Besides being at least as effective as prasugrel in inhibiting platelet aggregation, ticagrelor has been shown to have additional properties potentially affecting coronary microcirculation. We sought to compare the effects of ticagrelor and prasugrel on absolute coronary blood flow (Q) and microvascular resistance (R) in patients with stable coronary artery disease (CAD) undergoing elective percutaneous coronary intervention (PCI). The PROMICRO-3 study shows that in patients with stable CAD undergoing PCI pre-treatment with a loading dose of ticagrelor compared with prasugrel improves post-procedural coronary flow and microvascular function and seems to reduce the related myocardial injury.
A single center, prospective, observational study to investigate the impact of intravascular ultrasound (IVUS) on the functional percutaneous coronary intervention (PCI) result (assessed with fractional flow reserve (FFR)) and one-year target vessel failure (TVF) rate after percutaneous treatment of long coronary artery lesions
The goal of this observational study is to determine the diagnostic accuracy of peripheral whole blood transcriptomes analyzed by an artificial intelligence algorithm to detect the presence and extent of coronary calcification in individuals without a history of known cardiovascular disease. The main question it aims to answer is: 1. Will the proposed method predict the presence and extent of coronary artery calcification from the peripheral whole-blood transcriptomes?
Ischemic heart disease is the leading cause of death in the United States and worldwide (Nowbar et al., 2019). Exercise has been shown to be effective in preventing repeat heart attacks, hospitalizations and death among heart attack survivors (Lawler et al., 2011). But, few heart attack survivors -- particularly women -- get the recommended amount of physical activity (Minges et al., 2017; Gorczyca et al., 2017). The goal of this pilot study is to test the potential of an innovative new doctor-led exercise program to improve physical activity and quality of life for women who have had heart attacks in the past. Women who take part in the study will be randomly assigned to participation in the exercise program (which will consist of three 45-minute exercise sessions on Zoom per week) or usual care (attending medical appointments and following doctors' recommendations). All participants will be asked to wear Fitbit activity trackers to track steps every day, to use blood pressure cuffs to measure blood pressure at home, and complete a brief set of surveys at the beginning of the study, after 4 weeks, and after 12 weeks.
Investigating the myocardial effects of cold blood cardioplegia and del nido cardioplegia solution, which are routinely used in clinical practice, will contribute to the studies in the literature on the safety and efficacy of these two methods. For this purpose, patients with coronary artery disease that going to be Coronary Artery Bypass Graft (CABG) surgery will be classified within the scope of the SYNTAX score, the level of exposure to cardioplegia change in proportion to their score will be examined. Also, left ventricular muscle mass will be calculated in patients who will undergo Aortic Valve replacement (AVR) due to Aortic Stenosis, and myocardial protection level proportional to muscle mass will be examined, and cardioplegia efficiency will be compared.
About 200000 cardiac operations are performed in China every year. Cardiopulmonary bypass is the basic strategy of open-heart surgery, which may lead to myocardial ischemia-reperfusion injury and low cardiac output syndrome. It will inevitably affect the patient's postoperative recovery. A number of studies have shown that dexmedetomidine, as an auxiliary sedative, has the effects of inhibiting stress response, antiarrhythmia and cardiac protection.Dexmedetomidine has been widely used in anesthesia in cardiac surgery. However, at present, few clinical studies pay attention to its mechanism. In this study, dexmedetomidine will be used in cardiac surgery with cardiopulmonary bypass to explore the mechanism of cardiac ischemia-reperfusion injury and the protective effect of dexmedetomidine.
