Background: Increased blood hepcidin may be associated with the presence and promotion of atherosclerosis, the association of hepcidin with mortality among coronary artery disease (CAD) patients remains unknown. We sought to assess the relationship of hepcidin and all-cause and cardiovascular disease (CVD) mortality among CAD patients with and without acute coronary syndrome (ACS).
Methods And Results: This study included 759 patients with ACS and 526 patients with stable CAD. After an average follow-up of 4.1 years, 154 deaths were recorded, 114 were due to CVD. After adjusting for CVD risk factors and inflammatory markers, the plasma hepcidin was positively associated with all-cause and CVD mortality in the ACS patients, the multivariable-adjusted hazard ratios (HRs) across tertiles of hepcidin were 1.00, 2.18 (95% CI 1.23-3.94), and 2.82 (95% CI 1.59-5.12) for all-cause mortality (=0.006), and 1.00, 2.20 (95% CI 1.12-4.05), and 2.64 (95% CI 1.41-5.65) for CVD mortality (=0.01). The C-index and net reclassification improvement when including hepcidin in traditional CVD models were 1.6% and 21.5% for all-cause mortality, 1.4% and 23.5% for CVD mortality, respectively, (<0.001).
Conclusions: Plasma hepcidin was positively associated with mortality in ACS patients. Hepcidin may be a potential biomarker for risk prediction in ACS patients.

Introduction: Cardiovascular disease (CVD) is a leading cause of mortality on a global scale, with a higher prevalence observed among men. This study investigated the protective effect of vitamin D supplementation on CVD.
Methods: A cohort of thirty mice was divided into three groups: control, T1 diabetic, and T1 diabetic groups that received vitamin D treatment.

Background: Cardiac rehabilitation programs are planned to reduce the physiological and psychological stress of Cardiovascular Disease, decrease the risk of mortality secondary to CVD, improve cardiovascular function, and help patients to achieve their highest quality of life. However, data on the safety and efficacy of exercise training (ET) in patients with implantable cardioverter defibrillators (ICDs) is sparse. Exercise interventions in those with an ICD have not been extensively studied.

Background: Abdominal aortic calcification (AAC) is considered as a strong predictor of cardiovascular disease (CVD) events. Our study aimed to investigate whether the predicted risk for cardiac death with the Framingham risk score (FRS) could be further improved with the addition of AAC score in general population aged ≥ 40 years.
Methods: A total of 2971 participants aged ≥ 40 years in the National Health and Nutrition Examination Surveys (NHANES) 2013-2014 were followed up.

Lipid variability (LV) has been studied and proposed as a potential predictor for cardiovascular disease (CVD), and increased LV may contribute to adverse clinical outcomes. This study aimed to investigate the association of various LV parameters with the risk of long-term major adverse cardiovascular events (MACE) among the Thai population. The study used data from the CORE-Thailand Registry, a prospective multicentre study of adults with high cardiovascular risk or established CVD.

Positive results from cancer screenings, like a cancer diagnosis, can increase the risk of cardiovascular disease (CVD) mortality due to heightened psychological stress. However, positive screening results may also serve as a teachable moment to encourage the adoption of a healthier lifestyle. Consequently, the overall association between positive screenings and CVD mortality risk remains unclear.
