Seasonal Physical Activity in Patients With Heart Failure With Cardiac Implantable Electronic Devices

The aim of this observational study is to determine the effect of seasonal changes on physical activity levels in heart failure patients with cardiac implantable electronic devices. Patients with heart failure who have a cardiac implantable electronic device will be evaluated throughout the year.

Evaluation of Chronic Postsurgical Pain Risk in Patients Undergoing CIED Implantation Using an AID Support System

Chronic postsurgical pain (CPSP) remains a significant clinical and public health challenge despite major advances in surgical and anesthetic techniques. Patients receiving cardiac implantable electronic devices (CIEDs)-including pacemakers, implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy devices (CRTs)-constitute a unique population with high rates of multimorbidity, psychological vulnerability, and limited analgesic options due to cardiovascular comorbidities. Insufficient postoperative pain management in this group may lead to persistent pain at the generator site, neuropathic pain features, reduced quality of life, and increased healthcare utilization. The present study aims to evaluate the prevalence, risk factors, and clinical predictors of CPSP following CIED implantation using both subjective and objective pain assessments. Pain intensity will be measured using validated self-report scales (Visual Analog Scale and DN-4 questionnaire), and objective pain thresholds will be determined using a calibrated digital pressure algometer. Quality of life will be assessed with the validated Turkish version of the Short Form-12 (SF-12) instrument. This prospective observational study will include 180 adult patients who underwent first-time CIED implantation at Istanbul University-Cerrahpaşa, Cardiology Institute. Participants will be evaluated at 3, 6, and 12 months post-implantation. Collected data will include preoperative, intraoperative, and postoperative variables such as demographics, comorbidities, anesthesia type, surgical duration, and acute postoperative pain control. Using the obtained data, an artificial intelligence-based clinical decision support system will be developed to predict individual CPSP risk before implantation. The model will integrate subjective scales, objective algometric data, and clinical factors to generate personalized risk estimates. Ultimately, this system aims to improve early detection and prevention of CPSP, optimize postoperative pain management strategies, and enhance patient quality of life.

Proactive Risk Evaluation for Cardiac Implantable Electronic Device Strategy Using AI-ECG

The goal of this clinical trial is to learn whether an artificial intelligence-enhanced electrocardiogram (AI-ECG) strategy improves timely intervention of patients requiring cardiac implantable electronic devices (CIEDs), compared with standard clinical care.

Evaluation of the Validity and Reliability of the '6 Minute Pegboard and Ring Test' Unsupported Arm Function Exercise Test in Patients Using Pacemakers

Recently, the use of Cardiac Implantable Electronic Devices (CIED) is becoming widespread due to the improvement of patients' symptoms, reduction of sudden cardiac death and improved quality of life. Although implantation of the device is considered a minor invasive procedure, possible but often underestimated dysfunction of the same side upper extremity may develop after implantation. This increase in the number of device implantations makes shoulder dysfunction after pacemaker implantation a major health problem. In the current research in the literature, arm dysfunction is evaluated by measuring range of motion with a dynamic goniometer, scales scored independently of shoulder pathology and the effect of activities of daily living. This indicates that there is no objective functional assessment method used to evaluate arm function in CIED patients. Therefore, the point of this study is to find out how reliable and valid the 6 Minute Pegboard and Ring Test (6PBRT) is for testing the functional capacity of the upper extremity in people who have had CIED implanted.
