Filter by:Introduction: Coronary Artery Bypass Graft (CABG) performed with open heart surgery technique is a successful operation in the treatment of cardiovascular diseases. Incision of the sternum region, saphenous vein graft, sternal retraction, presence of chest and mediastinal tubes cause pain. The pain experienced by the patients, the complications related to the disease they have, and the stress they experience cause an increase in sleep problems. In addition, the increase in sympathetic activity after surgery and nursing care interventions also affect sleep quality. The literature reports that sleep disorders affect the working physiology of the heart in patients with cardiac disease, adversely affect heart health and affect postoperative recovery. In addition, since sleep disorders are also associated with cardiovascular diseases, it is of great importance to improve the sleep quality of this group of patients. One of the non-pharmacological nursing interventions is the eye patch. The eye patch is an instrument made of fabric, with an elastic strap, aimed at pure darkness by diverting all light from the patient's eyes. The main physiological purpose of using an eye patch is to adjust the hormones melatonin and cortisol, which affect the circadian rhythm. As a result, it is thought that the eye patch will prevent patients from being exposed to excessive light in the hospital environment, the regulation of hormones and sleep quality will improve, and the pain will decrease. Purpose: The aim of this study is to examine the effect of eye patch applied to patients undergoing coronary artery bypass graft surgery on sleep quality and pain. Method: Individuals who have undergone coronary artery bypass graft surgery in accordance with the sampling inclusion criteria will be randomly assigned to the experimental and control groups by block randomization. After determining the groups, each patient in the experimental and control groups, whose written consent was obtained, will have the first researcher fill out the Descriptive Characteristics Form, Richards-Campbell Sleep Questionnaire and Numerical Pain Scale on the morning of the first night they spent in the clinic. Patients in the experimental group will be given the "standard care" and "eye patch" application in the clinic on their 2nd and 3rd nights in the clinic. The patients in the control group will only be provided with the "standard care" in the clinic on their 2nd and 3rd nights in the clinic. Patients in both groups will be asked to fill out the Richards-Campbell Sleep Questionnaire and Numerical Pain Scale forms in the mornings of the 2nd and 3rd nights.
The goal of this clinical trial is to compare two guiding catheters in patients with coronary artery disease during a percutaneous coronary intervention between Guidex® Guiding catheter (DEMAX) and Launcher™ coronary guide catheters (Medtronic). The main question[s] it aims to answer are: - Aren't the safety of medical devices inferior to each other? - Aren't the efficacyof medical devices inferior to each other? Participants will be randomized (1:1) and have a percutaneous coronary interventionwith one of the two guiding catheters.
When performing coronary angiography in a stable situation, the identification of an intermediate coronary lesion (between 50 and 70%) is common, and requires additional functional evaluation. The gold standard for this evaluation is Fractional Flow Reserve (FFR). FFR is a flow ratio transformed into a pressure ratio by simplification, neglecting some parameters, especially microcirculatory resistance. The aim of this study is to investigate hemodynamic and structural assessment induced in specific conditions, and their repercussion on functional assessment by FFR to implement the diagnostic approach and personalize it for each patient.
The present case-control study is designed to investigate the disease characteristics of IR-CAD by comparing the demographics, clinical features, lab results, imaging findings, and prior treatment between 20 patients with IR-CAD and 10 patients with AS-CAD.
[The Purpose of the Clinical Study] The purpose of this randomized comparison study is to compare the 1-stent strategy with a drug-eluting balloon and the 2-stent strategy in patients with non-LM coronary true-bifurcation lesions. [Hypothesis] In this study, the researchers intend to verify the hypothesis that the 1-stent strategy with a drug-eluting balloon is non-inferior to the 2-stent strategy in terms of target lesion failures (cardiac death, target vessel MI, or target vessel revascularization).
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
This is a prospective pilot study to evaluate the safety, tolerability and efficacy of utilizing precise computer controlled gas challenge in healthy subjects for identification of coronary artery disease.
This is a prospective, multi-center, single-group study aims to evaluate the safety and efficacy of Alveo HP Balloon Dilatation Catheter for balloon dilatation of coronary artery stenosis. Pre-dilation with Alveo balloon dilatation catheter followed by conventional PCI, and follow-up will be carried out. During the trial, the enrollment, treatment and follow-up of the subjects will be recorded, and the safety and efficacy of the investigational device will be evaluated.
In order to perform heart surgery, a machine called cardiopulmonary bypass (CPB), or more commonly known as a heart-lung machine, is used to maintain the circulation of oxygenated blood needed by the rest of the body and its organs. Historically, when a patient is connected to CPB, their body is cooled below the normal body temperature. This is known as hypothermia. This is because scientific studies have previously shown that reduced body temperature lowers metabolism and therefore offers more protection to the brain and other organs due to the reduced oxygen requirement. The evidence supporting this practice, however, has been challenged throughout the history of cardiac surgery, with studies supporting that normothermia, or normal body temperature, is a safe alternative. Despite this, the practice of hypothermia has persisted. Published data from a survey of 139 cardiac surgeons in the United Kingdom showed that 84% still routinely employ hypothermic CPB during surgery. To assess whether normothermic or hypothermic CPB is safer, a clinical trial requiring a large sample size and high recruitment rates will be required. Therefore, the investigators aim to assess firstly the feasibility of trial recruitment and allocation adherence in this study. 100 adults across 10 different cardiac surgery centres in the United Kingdom will be recruited to a multicentre feasibility randomised controlled trial comparing normothermia (active comparator) against hypothermia (control comparator) during cardiopulmonary bypass in cardiac surgery. This study will also test the ability of the Cardiothoracic Interdisciplinary Research Network (CIRN), a trainee-led research collaborative, to collect pilot data on Major Adverse Cardiac and Cerebrovascular Events (MACCE) using a regulation-approved electronic application HealthBitⓇ. Participants will also be asked to complete quality of life surveys. The results of this study will subsequently inform a large, adequately powered randomised controlled trial for optimal temperature management during CPB.
Early detection of coronary atherosclerotic disease facilitates adequate prevention. The purpose of this study is to compare an assessment of coronary atherosclerotic disease burden by positron emission tomography / computed tomography (NaF-PET/CT) with those of conventional and ultra-high-resolution-CT (UHR-CT) in patients with suspected coronary artery disease. For this purpose, the investigators plan to include 33 patients with symptoms concerning for CAD who have been referred for cardiac CT testing.
