Understanding cardiopulmonary interactions through esophageal pressure monitoring

open access: yesFrontiers in Physiology, 2023
Esophageal pressure is the closest estimate of pleural pressure. Changes in esophageal pressure reflect changes in intrathoracic pressure and affect transpulmonary pressure, both of which have multiple effects on right and left ventricular performance ...

Cardioprotective effects of early intervention with sacubitril/valsartan on pressure overloaded rat hearts

open access: yesScientific Reports, 2021
Left ventricular remodeling due to pressure overload is associated with poor prognosis. Sacubitril/valsartan is the first-in-class Angiotensin Receptor Neprilysin Inhibitor and has been demonstrated to have superior beneficial effects in the settings of ...
