Recurrent cardiac ischemia after coronary artery bypass graft surgery occurs in a significant proportion of patients, prompting repeat investigations and incurring significant clinical and financial costs. Noninvasive investigations to identify graft occlusion and quantify graft stenosis are desirable due to the complications, cost, and patient inconvenience of invasive coronary angiography. The increasing use of 64-slice multislice computed tomography has led to multiple reports on its accuracy in graft stenosis and occlusion. This review focuses on image acquisition and manipulation techniques, interpretative pitfalls, and the diagnostic performance of 64-slice multislice computed tomography in coronary artery bypass graft imaging across the medical literature.

Cardiac disease refers to diseases that affect the heart such as coronary artery diseases, arrhythmia and heart defects and is amongst the most difficult health conditions known to humanity. According to the WHO, heart disease is the foremost cause of mortality worldwide, causing an estimated 17.8 million deaths every year it consumes a significant amount of time as well as effort to figure out what is causing this, especially for medical specialists and doctors.

Purpose: To study the effects of breathing exercises on preventing pulmonary complications in patients undergoing coronary artery bypass graft surgery.
Methods: Observing whether preoperative breathing exercises can reduce the incidence of postoperative pulmonary complications in patients undergoing coronary artery bypass graft surgery; observing whether these exercises can improve postoperative arterial oxygen pressure, oxygen saturation, and the distance walked in a six-minute walk test after surgery; as well as reduce hospital stay duration, lower treatment costs, and improve the quality of life as measured by the Short Form-36 Health Survey (SF-36).
Design: The study population includes patients undergoing coronary artery bypass graft surgery under general anesthesia; the research center is Capital Medical University Xuanwu Hospital; the sample size is 120.

Introduction: Chronic inflammation is a major risk factor for coronary artery disease (CAD). Currently, the inflammatory cardiovascular risk is assessed via C-reactive protein (CRP) levels measured using a high-sensitivity assay (hsCRP). Monomeric CRP (mCRP) is a locally produced form of CRP that has emerged as a potential biomarker of inflammation.

Background: Fatty liver disease or steatotic liver disease (SLD) affects 25% of the global population and has been associated with heart disease. However, there is a lack of postmortem studies in the context of sudden cardiac death (SCD).
Objectives: To investigate the relationship between SLD and SCD.

Objective: To explore the risk factors associated with postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCABG) and to construct a nomogram predictive model.
Methods: In this retrospective cohort study, clinical data of 193 patients who received OPCABG in Huai'an First People's Hospital Affiliated to Nanjing Medical University from June 2021 to November 2023 were retrospectively analyzed. Based on the established diagnosis of POAF, patients were divided into the POAF group (n=75) and the non-POAF group (n=118).
