充血性心力衰竭患者的焦虑是普遍存在的？

You are evaluating the degree of congestive heart failure in a preoperative patient with dyspnea on exertion. Increased sympathetic tone in congestive heart failure may be indicated by______

(A) memory loss     (B) weakness

(C) fatigue             (D) confusion

(E) anxiety

(E) The anxiety seen in patients with congestive heart failure is due to increased sympathetic activity. The increased sympathetic activity is a compensatory mechanism, and it is not directly related to the low flow state, as are the other options. Memory loss, weakness, fatigue, and confusion are directly caused by low output.

第一句：The anxiety seen in patients with congestive heart failure is due to increased sympathetic activity.充血性心力衰竭患者的焦虑是由于交感神经活动增加所致。那么我是不是可以理解：充血性心力衰竭患者的焦虑是普遍存在的,因为充血性心力衰竭患者的交感神经活动增加是普遍存在的
