    Abstract : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).

    Abstract : Background: Acute pulmonary embolism (PE) is the third most common cardiovascular disease following myocardial infarction and stroke. Despite diagnostic improvements, the diagnosis of PE is still associated with many difficulties, as the symptoms of an acute PE are nonspecific. READ MORE

    Abstract : Pulmonary hypertension (PH) is a pathophysiological state associated with several medical conditions, leading to progressive rise in pulmonary vascular resistance (PVR) and right ventricular failure. The clinical PH classification encompasses five main World Health Organization (WHO) groups; pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxia, chronic thromboembolic PH, and PH with unclear multifactorial mechanisms.
