A 55-year-old woman who is obese comes to the physician because of daytime drowsiness, early morning headaches, and swollen ankles. During the interview, she says, "My husband tells me I snore too loudly. He can't get any sleep because of it." Echocardiography shows an enlarged right ventricle and poor right ventricular function. Which of the following is most likely responsible for the development of right ventricular failure in this patient?
A. Increased pulmonary artery pressure
B. Increased right ventricular preload
C. Pulmonary embolism
D. Pulmonary valve stenosis
E. Transient hypoxia in right ventricular myocardium
