Effects of Stress Ball Use During Femoral Catheter Removal After Coronary Angiography

This study aimed to evaluate the effects of using a stress ball during femoral catheter removal on quality of recovery, patient comfort, and pain in adults undergoing coronary angiography. The study was conducted at a hospital in Istanbul, Türkiye, between November 2024 and May 2025. A total of 84 patients participated in this randomized controlled trial. Participants were randomly assigned to one of two groups, with 42 patients in each group. Patients in the intervention group were asked to repeatedly squeeze and release a stress ball during femoral catheter removal. Patients in the control group received routine clinical care without the stress ball intervention. Pain was assessed 15 minutes after catheter removal. Quality of recovery and patient comfort were evaluated before discharge using standardized assessment scales. The study was designed to determine whether stress ball use could improve recovery and comfort and reduce pain during care following coronary angiography.

Breathing Meditation and VR Nature Videos in Angiography Patients: Effects on Anxiety, Comfort, and Physiology

This study was designed to evaluate the effects of breathing meditation, accompanied by virtual reality (VR)-enhanced nature videos, on anxiety, comfort, pain, and physiological parameters in patients undergoing angiography. Prior to the procedure, pain levels in patients in both groups will be assessed using the Visual Analog Scale (VAS); the State Anxiety Inventory and the General Comfort Scale will be administered; and physiological parameters will be recorded. Patients in the intervention group will be fitted with VR headsets 5 minutes before the start of the angiography procedure and will undergo breathing meditation accompanied by nature videos. Patients in the control group, on the other hand, will receive routine standard nursing care and will not undergo the VR intervention. During the procedure, pain levels and physiological parameters will be assessed in patients from both groups. Following the angiography, the VAS, State Anxiety Inventory, and General Comfort Scale will be re-administered in both groups, and physiological parameters will be recorded again. By comparing the data obtained from both groups at the same measurement points, the effect of VR-supported nature video-guided breathing meditation on patients' anxiety, comfort, pain, and physiological parameters will be determined.

The Effect of Using Virtual Reality Glasses During Coronary Angiography

Coronary angiography (CAG) is a diagnostic method used as the gold standard in the diagnosis of coronary artery disease (CAD), which is increasingly prevalent in developed and developing countries and is one of the leading causes of morbidity and mortality in the world. Although coronary angiography is one of the best diagnostic methods of CAD, it can cause psychological problems such as stress, fear, anxiety in patients; It also causes physical problems such as bleeding, hematom and pain. Pharmacological and non-pharmacological methods are used by nurses to solve problems of patients, to ensure their relaxation and to improve their quality of life. With the development of technology, virtual reality (VR) glasses have been used to have fun at first, and later to provide pain management and to solve anxiety problems. VR glasses are an advanced technology that allows the patient to move into a virtual world and focus his attention on other thoughts, giving less attention to pain and anxiety. During literature search, no studies were found about the effect of using SG glasses on pain and anxiety during CAG. This research will be conducted to determine the effect of VR glasses used during CAG on pain, anxiety and hemodynamic parameters of patients who will experience coronary angiography for the first time.

HEMOSTATİC PAD AND SANDBAG

The aim of this study is to compare bleeding outcomes, pain, comfort levels, sleep quality, and associated factors among patients receiving a chitosan-based hemostatic pad versus a sandbag following femoral coronary angiography (CAG) and percutaneous coronary intervention (PCI). Femoral coronary angiography (CAG) and percutaneous coronary intervention (PCI) are widely performed procedures for the diagnosis and treatment of coronary artery disease (CAD), which remains the leading cause of mortality worldwide (Batmaz \& Cengiz, 2023; Wardiyana et al., 2024). Hemostasis following CAG and PCI is critical for preventing life-threatening complications, ensuring procedural success, and facilitating recovery. Vascular complications at the femoral arterial puncture site are among the most common adverse events associated with these procedures (Chen et al., 2021). Inadequate hemostasis may result in serious complications such as pseudoaneurysm, arteriovenous fistula, and retroperitoneal hemorrhage, all of which may pose significant risks to patient safety (Sauer et al., 2016). Effective bleeding control is particularly important in patients receiving intensive anticoagulant therapy. Following manual compression, sandbag application is commonly used to maintain hemostasis at the femoral access site. Typically, a sandbag weighing between 2.3 and 5 kilograms is placed over the puncture site, requiring patients to remain in a supine position with restricted mobility for approximately four to six hours (Batmaz \& Cengiz, 2023). Although prolonged bed rest and sandbag application contribute to hemostasis, they may also lead to adverse patient experiences, including pain, discomfort, urinary retention, restlessness, and impaired sleep quality (Batmaz \& Cengiz, 2023). Advances in medical technology have led to the development of hemostatic devices designed to rapidly control bleeding independently of the body's natural coagulation mechanisms. Among these, chitosan-based hemostatic pads, derived from crustacean shells, have attracted increasing attention. Due to their positive electrical charge, chitosan molecules attract negatively charged erythrocytes and platelets, facilitating the rapid formation of a mechanical barrier and clot within seconds (Arbel et al., 2010; Kılıç et al., 2024). Previous studies have demonstrated that chitosan-based pads may reduce manual compression time and vascular complications such as ecchymosis and hematoma (Ginanjar et al., 2018; Kılıç et al., 2024; Qian et al., 2024). Furthermore, they have been associated with improved patient comfort, earlier mobilization, and shorter hospital stays (Kılıç et al., 2024; Liu, 2025). The responsibilities of nurses following CAG and PCI extend beyond bleeding control and include comprehensive monitoring of vital signs, early detection of complications, and the promotion of patient comfort and well-being (Batmaz \& Cengiz, 2023; Rodrigues et al., 2024). While existing studies have primarily focused on the effectiveness of chitosan-based pads in reducing hematoma formation (Bektaş et al., 2017), evidence regarding their effects on broader patient-centered outcomes remains limited. Therefore, this study seeks to provide a comprehensive evaluation of chitosan-based hemostatic pads and conventional sandbag application with respect to bleeding outcomes, pain, patient comfort, and sleep quality. Accordingly, the present study aims to compare bleeding, pain, comfort levels, sleep quality, and related factors among patients undergoing femoral CAG and PCI who receive either a chitosan-based hemostatic pad or a sandbag for post-procedural hemostasis. The sample size was calculated using a power analysis based on an effect size of 0.40, a significance level of 5% (α = 0.05), and a statistical power of 80% (1-β = 0.80). According to the analysis, a total of 480 participants will be recruited, including 240 patients in the chitosan-based hemostatic pad group and 240 patients in the sandbag group.

Hypnosis Efficacy for the Prevention of Anxiety During a Coronary Angiography

The purpose of this study is to confirm the utility for hypnosis in the coronary angiographic examination. The technique would be an alternative to prevent the consumption of anesthesic drugs.

Timing of Anticoagulant Administration During Radial Access Percutaneous Coronary Intervention: the HERA-PCI Study (Heparin Early for Radial Access Percutaneous Coronary Intervention)

While the reduced hemorrhagic risk of radial access for percutaneous coronary intervention compared to femoral access is well-established, its main complication remains radial artery occlusion, which can occur in up to 30% of patients. Anticoagulation is the primary preventive measure recommended in clinical practice to reduce the risk of this complication, typically involving heparin injection during the procedure in most centers. However, data on the effect of the timing of heparin injection are limited. The investigators hypothesize that injection of heparin before sheath insertion may reduce the rate of radial artery occlusion compared with injection after sheath insertion.

Incidental Findings on Coronary Computed Tomography Angiography

Coronary CT angiography (CCTA) is increasingly used for ischemic heart disease diagnosis. The rising number of CCTA tests has led to a significant increase in the number of finding unexpected incidental extracardiac diseases.
