Pulmonary embolism (PE) is a potentially lethal condition, although frequently diagnosed, and is rarely associated with transit on initial presentation. Heparin-induced thrombocytopenia (HIT) can cause both arterial thrombus formation and venous thromboembolism. The two forms of HIT must be differentiated in order to guide management. We present a complex and unique case of PE in transit secondary to HIT diagnosed in a patient with a negative serotonin assay.

Background/aim: Atrial fibrillation (AF) and heart failure (HF) commonly co-occur, significantly increasing morbidity and mortality. Poorly controlled AF can contribute to complications like HF and is associated with conditions, such as stroke and pulmonary embolism (PE). This report involves a man with AF who had persistent respiratory symptoms and left-sided chest pain, initially suspected to be PE, but eventually diagnosed as HF.

Background: Epidemiological studies have consistently demonstrated a robust association between long-term exposure to air pollutants and respiratory diseases. However, establishing causal relationships remains challenging due to residual confounding in observational studies. In this study, Mendelian randomization (MR) analysis was used to explore the causal and epigenetic relationships between various air pollutants and common respiratory diseases.
