A 43-year-old woman has congestive heart failure after a myocardial infarction. Before the myocardial infarction, she had a cardiac output of 5 L/min and a right atrial pressure of 0 mm Hg at rest. The solid curve in the graph shows the relationship between right atrial pressure and cardiac output in a normal heart. Which of the following lettered points best represents the change in this relationship after the development of congestive heart failure?
