A 36-year-old man presents to his primary care physician because of shortness of breath. He is an office worker who has a mostly sedentary lifestyle; however, he has noticed that recently he feels tired and short of breath when going on long walks with his wife. He also has had a hacking cough that seems to linger, though he attributes this to an upper respiratory tract infection he had 2 months ago. He has diabetes that is well-controlled on metformin and has smoked 1 pack per day for 20 years. Physical exam reveals a large chested man with wheezing bilaterally and mild swelling in his legs and abdomen. The cause of this patient's abdominal and lower extremity swelling is most likely due to which of the following processes?

Right ventricular dysfunction secondary to pulmonary hypertension

A 61-year-old man comes to the physician for shortness of breath and chest discomfort that is becoming progressively worse. He has had increasing problems exerting himself for the past 5 years. He is now unable to walk more than 50 m on level terrain without stopping and mostly rests at home. He has smoked 1–2 packs of cigarettes daily for 40 years. He appears distressed.

Which of the following is the most likely cause of this patient's symptoms?

Perforation of the esophageal wall

Obstruction of the pulmonary arteries

Fibrofatty plaque in the aortic wall

Dynamic left ventricular outflow tract obstruction
