What is this article about?
Heart failure (HF) is typically described as left or right HF, which is somewhat simplistic since the functions of the left and right ventricles are inextricably intertwined. However, the terminology is still useful since it points out which ventricle (left or right) is primarily affected. In left HF, the left ventricle fails, defaulting on its duties as a pump to the periphery. The patient is left with a highly ineffective blood transport system for the body. In right HF, the right ventricle is the chief culprit. Blood does not flow properly to the lungs; this results in a reduction in gas exchange in the alveoli. Pulmonary hypertension in left heart disease (PH-LHD) is the most common form of pulmonary hypertension.
