<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 60-year-old obese man comes to the emergency department with tightness in his chest and lower extremity edema. He has a history of heart failure that has gotten worse over the last several years. He takes finasteride, lisinopril, and albuterol. He does not use oxygen at home. He has mildly elevated blood pressure, and he is tachycardic and tachypneic. Physical examination shows an overweight man having difficulty speaking with 2 pitting edema on his lower extremities up to his thighs. The attending asks you to chart out the patients theoretical cardiac function curve from where it was 5 years ago when he was healthy to where it is right now. What changes occurred in the last several years without compensation?? A: Cardiac output went up, and right atrial pressure went down, B: Cardiac output went down, and right atrial pressure went up, C: Cardiac output went down, and right atrial pressure went down, D: Cardiac output went up, and right atrial pressure went up, E: Both cardiac output and right atrial pressures are unchanged,  <response>: This is a question about heart failure pathophysiology. The patient described has a history of worsening heart failure over several years. Key findings include lower extremity edema, difficulty speaking, tachycardia, tachypnea, and a history of worsening heart failure. In heart failure, the heart is unable to pump out enough blood to meet the bodys needs. This leads to a decrease in cardiac output. Fluid backs up behind the failing heart, leading to an increase in filling pressures like right atrial pressure.So over the past several years in this patient, as his heart failure worsened without compensation, his cardiac output decreased and his right atrial pressure increased.B: Cardiac output went down, and right atrial pressure went up
