Abstract:
A 51-year-old female patient with a recent hospital admission reported to the emergency room (ER) with progressive worsening of fatigue, dyspnoea and chest discomfort. She had been recently admitted and discharged with the diagnosis of pericarditis and medicated with non-steroidal anti-inflammatory drugs and diuretics. She returned to the ER with persisting symptoms. Echocardiography was repeated and showed signs of elevated right ventricular systolic pressure and a slightly increased moderate/severe pericardial effusion without signs of cardiac tamponade. The patient was admitted and further evaluation confirmed an underlying case of advanced systemic sclerosis with skin, vascular, pulmonary and cardiac involvement. The patient was referred to specialised consults in autoimmune pathology and pulmonary arterial hypertension. She was started on bosentan and corticosteroids, presenting a favourable clinical evolution although symptoms of exertional dyspnoea persist.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
