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.
The aim of the present study will be to identify different phenotypes of microvascular dysfunction and their associations with the severity of anginal symptoms assessed through the Seattle Angina Questionnaire(SAQ-7).
The role of soluble circulating suppression of tumorigenicity 2 biomarker (sST2) in the ischemic heart disease patient is a debatable point. Therefore the aims of this study are to assess the plasma level of sST2 in ischemic heart disease patients versus non-ischemic ones, the acute changes in its level after percutaneous coronary intervention (PCI) and its relation to the severity of ischemia.
In patients with 50-90% stenosis of the coronary artery, the coronary roadmap (dynamic roadmap) is performed when the conventional fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are performed. coronary roadmap system) to confirm the effectiveness of the function.
The goal of this randomized controlled clinical trial in asymptomatic individuals with risk factors for cardiovascular disease is to investigate whether a preventive treatment strategy guided by computed tomography coronary angiography (CTCA) provides a patient-centered approach, which ensures optimal protection against serious cardiovascular disease. The main question it aims to answer is: Does preventive treatment guided by CTCA reduce the risk of heart attacks or cardiovascular death as compared to using conventional cardiovascular risk scores. Participants will be randomized to preventive medical therapy and/or invasive intervention guided by either CTCA (intervention group) or Systematic COronary Risk Evaluation (SCORE) 2 model for cardiovascular risk prediction (control group).
The goal of this observational study is to test the feasibility of intracoronary adenosine administration during coronary flow reserve(CFR) and index of microcirculatory resistance(IMR) assessment in a population with angina. The main questions it aims to answer are: - Repeatability of CFR and IMR assessment while hyperemia with intracoronary adenosine was administered. - Evaluate the correlation of the intrinsic signal of coronary waveform versus physiologic ischemia, while defined by fractional flow reserve(FFR) and CFR respectively. - The predictive value of FFR, CFR, and IMR on major adverse cardiovascular outcomes in 3 years Participants will undergo FFR, CFR, and IMR assessments in the catheterization laboratory of the National Taiwan University Hospital Hsin-Chu Branch, then clinical events follow up for 3 years.
The FAVOR V AMI study is a prospective, multicenter, blinded, randomized, sham-controlled trial comparing the long-term clinical outcomes of the "Functional and Angiography-derived Strain inTegration (FAST)" technique (next-generation quantitative flow ratio [μQFR] and radial wall strain [RWS]) guided percutaneous coronary intervention (PCI) strategy, with standard treatment strategy, in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary disease (MVD).
