Objective: This study aims to develop a novel risk assessment tool for coronary artery disease (CAD) based on data of patients with chest pain in outpatient and emergency department, thereby facilitating the effective identification and management of high-risk patients.
Methods: A retrospective analysis was conducted on patients hospitalized for chest pain. Patients were divided into a control group and a CAD group based on angiographic results. Logistic regression was used to identify factors associated with CAD, and R-Studio was utilized to construct the CAD risk prediction model.
Results: Multivariate logistic regression analysis indicated that age, gender, diabetes, ECG (electrocardiogram) ST-T changes, neutrophils (NE), coronary artery calcification (CAC), and typical chest pain were independent factors associated with CAD. Based on the results of multifactorial logistic analysis, the CAD risk prediction model built with R-Studio had a highest C-index of 0.909, and a validation cohort C-index of 0.897, demonstrating excellent predictive ability. Decision Curve Analysis showed that the model significantly outperformed others in terms of clinical net benefit.
Conclusion: The present study successfully developed a CAD risk assessment model based on Chinese population. This novel model could be used to assess CAD risk in patients with chest pain, optimize clinical decision making, and improve patient outcomes, regardless of whether it is applied in large hospitals or resource-limited Community Healthcare Center.

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is a rare condition caused by an immune response associated with over-reactivity of the immune system, triggered by adjuvants. The most common adjuvants are aluminium salts but can also be bioimplants or infectious agents. It may lead to the development of various autoimmunologic diseases.

Background And Objective: Cardiovascular disease (CVD), one of the chronic non-communicable diseases (NCDs), is defined as a cardiac and vascular disorder that includes coronary heart disease, heart failure, peripheral arterial disease, cerebrovascular disease (stroke), congenital heart disease, rheumatic heart disease, and elevated blood pressure (hypertension). Having CVD increases the mortality rate. Emotional stress, an indirect indicator associated with CVD, can often manifest through facial expressions.

Background And Aim: Removing the chest tube in cardiac patients after surgery is one of the worst experiences of hospitalization in the intensive care units. Various pharmacological and non-pharmacological methods are available to control pain in these patients. This study aimed to investigate the combined effect of reflexology massage and respiratory relaxation on pain following chest tube removal in cardiac surgery patients of Shahid Beheshti Hospital in Shiraz, Iran, in 2023.
