Cardiac dyspnea, especially if present only with exercise, is often confused with asthma and exercise-induced bronchospasm. Cardiac dyspnea or asthma is the consequence of pulmonary edema due to pulmonary venous hypertension and not due to asthmatic bronchoconstriction. In overt, acute congestive heart failure, the diagnosis may be readily made by history and physical examination and pertinent laboratory and imaging data.
心源性呼吸困难，特别是仅在运动时出现的呼吸困难，常与哮喘和运动诱发的支气管痉挛相混淆。心源性呼吸困难或哮喘是由于肺静脉高压导致肺水肿的结果，而不是由于哮喘性支气管痉挛。在明显的急性充血性心力衰竭中，通过病史、体格检查以及相关的实验室和影像学数据可以很容易地做出诊断。
