Background And Objective: Dysfunction of the right ventricle (RV) is a parameter of severity in acute pulmonary embolism (PE). Echocardiographic assessment is not always possible in accident and emergency, hence the need to predict the presence of RV dysfunction using easily measurable parameters. To analyse the value of NT-proBNP and troponin T as markers of RV dysfunction in patients with acute PE. Secondarily, to assess the relationship between RV failure and clinical parameters related to PE.
Material And Method: Analytical, observational, cross-sectional and retrospective study comparing the values NT-proBNP, troponin T and presenting symptoms of PE among patients with and without RV dysfunction.
Results: One hundred seventy-two patients (52 with RV failure,120 without) were included. All symptoms occurred with similar frequency between the 2groups except dyspnea and syncope (more common in the group with RV failure). Both NT-proBNP and troponin T had significantly higher values in the group of patients with RV dysfunction. However, in the multivariate analysis, NT-proBNP had a higher explanatory value for RV failure than troponin T.
Conclusion: NT-proBNP is a diagnostic parameter of RV dysfunction with higher sensitivity in the context of acute PE.

Background: Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a rare and progressive mitochondrial disorder characterized by multi-systemic involvement. This disease manifests in various clinical manifestations, with heart and kidney disorders being among the most common. Accurate diagnosis of MELAS often necessitates a range of complex investigations.

Background: COVID-19 is associated with intense systemic inflammation and abnormal coagulation profile leading to an increased incidence of pulmonary embolism (PE). This study investigates whether PE in COVID-19 patients has different clinical, laboratory and radiological characteristics when compared to traditional PE in COVID negative patients.
Methods: We conducted an observational, multicentric, cross-sectional study on consecutive patients diagnosed with PE at admission or during hospital stay from February 21 2019 to February 20 2021.

: 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.

Background: Cardiovascular disease (CVD) remains the leading cause of death in pregnant and peripartal women in western countries. Physiological changes during pregnancy can lead to cardiovascular complications in the mother; women with pre-existing heart disease may not tolerate these changes well, increasing their susceptibility to adverse cardiovascular outcomes during pregnancy. The aim of this study is to characterize pregnancy-induced changes in cardiac function, biomarker concentrations and cardiovascular outcomes in women with CVD during pregnancy at a tertiary care hospital in Germany.

Background: Vanadium (VAN) is a significant trace element, but its higher exposure is reported to cause severe organ toxicity. Tectochrysin (TEC) is a naturally derived flavonoid which demonstrates a wide range of pharmacological properties.
Aim: The current study was planned to assess the cardioprotective potential of TEC against VAN induced cardiotoxicity in rats via regulating biochemical, and histological profile.
