Induction of cyclooxygenase-2 (COX-2) in ischemic myocardium is thought to increase the production of proinflammatory prostanoids and contribute significantly to the ischemic inflammation. Left ventricular myocardial infarction (MI) was created by ligating the left coronary artery in Lewis rats. Hemodynamic measurements at 4 weeks showed better cardiac function in the group treated with a selective COX-2 inhibitor (DFU; 5 mg/kg/day) for 2 weeks after induction of MI compared to the vehicle treated group. These results suggest that induction of COX-2 contributes to myocardial dysfunction, and that selective inhibition of COX-2 could constitute an important therapeutic target for the treatment of MI.

Bioprinting approaches in cardiac tissue engineering to reproduce blood-pumping heart function.

The heart, with its complex structural and functional characteristics, plays a critical role in sustaining life by pumping blood throughout the entire body to supply nutrients and oxygen. Engineered heart tissues have been introduced to reproduce heart functions to understand the pathophysiological properties of the heart and to test and develop potential therapeutics. Although numerous studies have been conducted in various fields to increase the functionality of heart tissue to be similar to reality, there are still many difficulties in reproducing the blood-pumping function of the heart.

Background: Cardiac autonomic neuropathy (CAN) is a significant complication in chronic kidney disease (CKD), leading to increased morbidity and mortality. Early detection is essential for managing CKD patients effectively, especially those on hemodialysis. This study evaluated the prevalence CAN in CKD and diagnostic accuracy of Bellavere's Score in predicting CAN in CKD patients, including those undergoing hemodialysis.

Department of Cardiology, Leiden University Medical Center, Leiden, the Netherlands.
Background: Epicardial fat tissue (EFT) is an active organ that can affect cardiac function and structure through endocrine, paracrine, and proinflammatory mechanisms. We hypothesized that greater thickness of EFT may harm the recovery of left ventricular (LV) systolic function in patients with severe aortic stenosis (AS) and reduced LV ejection fraction (EF ≤ 50 %) undergoing transcatheter aortic valve implantation (TAVI).
Methods: A sixty six patients with severe AS and 20 % ≥ LVEF ≤ 50 % who underwent TAVI were included.

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.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.
