Background: Atrial fibrillation (AF) persistence is associated with molecular remodeling that fuels electrical conduction abnormalities in atrial tissue. Previous research revealed DNA damage as a molecular driver of AF.
Objectives: This study sought to explore the diagnostic value of DNA damage in atrial tissue and blood samples as an indicator of the prevalence of electrical conduction abnormalities and stage of AF.
Biomarkers of Importance in Monitoring Heart Condition After Acute Myocardial Infarction.

Cardiothoracovascular Department, Azienda Sanitaria Universitaria Giuliano Isontina, 34100 Trieste, Italy.
Despite notable advancements in cardiovascular medicine, morbidity and mortality rates associated with myocardial infarction (MI) remain high. The unfavourable prognosis and absence of robust post-MI protocols necessitate further intervention. In this comprehensive review, we will focus on well-established and novel biomarkers that can provide insight into the processes that occur after an ischemic event.

We investigated the accuracy of predicting preload responsiveness by means of a passive leg raising test (PLR) using the perfusion index (PI) in critically ill patients showing signs of hypoperfusion in a resource-limited setting. We carried out a prospective observational single center study in patients admitted for sepsis or severe malaria with signs of hypoperfusion in Chattogram, Bangladesh. A PLR was performed at baseline, and at 6, 24, 48, and 72 h.

Department of Cardiology, The Affiliated Hospital of Xuzhou Medical University, No.99 West Huaihai Road, Quanshan District, Xuzhou, 221000, China.
Background: MicroRNAs (miRNAs) are closely related to cardiovascular diseases, including chronic heart failure (CHF). Endothelial dysfunction can lead to heart failure. The purpose of this study was to evaluate the clinical significance of miR-1285-3p in CHF patients, with the aim of identifying a novel and effective biomarker for CHF.

School of Medicine, University of Split, 21000 Split, Croatia.
: Pulmonary embolism (PE) is a potentially serious condition characterized by the blockage of blood vessels in the lungs, often presenting significant diagnostic challenges due to its non-specific symptoms. This study aimed to evaluate the utility of the alveolar-arterial (A-a) oxygen gradient as a diagnostic tool for PE, hypothesizing that it could enhance early detection when combined with other clinical markers. : We retrospectively analyzed 168 patients at the University Hospital Center Split.
