Moreover, it is a well-established metabolic risk factor for diabetes mellitus, hypertension, and various types of cancer, as well as cardiovascular diseases such as heart failure and coronary artery disease. Body mass index (BMI) is calculated by dividing body weight in kilograms by the square of height in meters and is widely used as an indicator of obesity. However, BMI does not quantitatively reflect body fat distribution and fails to account for components such as skeletal muscle and bone mass. Therefore, interest in assessing body fat distribution has increased, and in recent years, studies evaluating the correlation between anthropometric, biochemical, and anatomical measurements and clinical outcomes have become more frequent. In particular, it is acknowledged that abdominal obesity cannot be accurately represented by BMI alone and is primarily associated with visceral adipose tissue (VAT). The aim of this study is to evaluate the association between preoperative visceral and subcutaneous adipose tissue measurements (VAT and SAT), assessed by ultrasonography in patients scheduled for open-heart surgery, and the development of postoperative atrial fibrillation.",[24,25,26],"CABG","Visceral Adipose Tissue","Atrial Fibrillation (AF)",[26,25,24],"NOT_YET_RECRUITING","2026-03-08",{"date":31,"type":32},"2026-03-12","ACTUAL",{"date":34,"type":20},"2026-04-01",{"date":36,"type":20},"2027-01-22",{"name":38,"class":39},"Kartal Kosuyolu Yuksek Ihtisas Education and Research Hospital","OTHER_GOV",{"id":41,"slug":42,"hasResults":11,"nctId":43,"briefTitle":44,"officialTitle":45,"acronym":4,"eligibilityCriteria":46,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":47,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":49,"conditions":50,"keywords":4,"overallStatus":57,"whyStopped":4,"lastUpdateSubmitDate":58,"lastUpdatePostDateStruct":59,"startDateStruct":61,"completionDateStruct":62,"leadSponsor":64,"locationsCount":5},"100622998","gls-in-difficult-cpb-weaning-100622998","NCT07390903","GLS in Difficult CPB Weaning","Global Longitudinal Strain as a Predictor of Difficult Separating From Cardiopulmonary Bypass","Inclusion Criteria\n\n* Age \\> 18 years.\n* Scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CPB).\n* Provided written informed consent to participate.\n* Eligible surgical procedures include:\n\n  * Isolated mitral valve replacement or repair.\n  * Isolated aortic valve replacement or repair.\n  * Isolated coronary artery bypass grafting (CABG).\n  * Combined valve and CABG surgery.\n  * Multiple valve replacement or repair.\n  * Surgery involving the ascending aorta or aortic arch.\n\nExclusion Criteria\n\n* Emergency cardiac surgery.\n* Redo cardiac surgery.\n* Contraindications to transesophageal echocardiography (TEE).\n* Critical preoperative conditions, including:\n\n  * Ongoing inotropic drug therapy.\n  * Preoperative mechanical circulatory support (e.g., IABP, ECMO, VAD).\n  * Requirement for mechanical ventilation.\n  * Preoperative atrial fibrillation.",{"count":48,"type":20},213,"The goal of this observational study is to learn whether global longitudinal strain (GLS), measured by echocardiography, can predict difficulty separating from cardiopulmonary bypass (CPB) in adults undergoing elective cardiac surgery.\n\nThe main questions it aims to answer are:\n\n* Can preoperative GLS measurement predict difficult separation from CPB?\n* Are GLS values associated with outcomes such as intensive care unit (ICU) stay, hospital stay, cardiac biomarkers, or 30-day mortality?\n\nParticipants will:\n\n* Undergo standard cardiac surgery requiring CPB\n* Have echocardiographic assessments (TTE before and after surgery)\n* Have their recovery and outcomes monitored, including ICU and hospital stay, postoperative labs, and survival within 30 days",[51,52,53,54,55,56],"Cardiopulmonary Bypass","Coronary Artery Bypass","Heart Valve Diseases","Echocardiography","Intraoperative Complications","Postoperative Complications (Cardiopulmonary)","RECRUITING","2026-02-01",{"date":60,"type":32},"2026-02-05",{"date":60,"type":20},{"date":63,"type":20},"2026-08-30",{"name":38,"class":39},""]
