限制心力衰竭病人活动的症状很难加以评定。病人对气促的感觉因人而异。传统的说法认为,心脏病病人呼吸困难是由于左心房压升高,活动时心输出量不足而引起疲劳。这种简单的观点对于急性心力衰竭可能是正确的。可以肯定,呼吸困难和肺水肿的发生确与左心房压相关。降低左心房压的药物一般能解除呼吸困难。引起慢性心力衰竭临床综合征的主要现象是心室机能障碍。因此,医师推测活动量可能与左心室机能障碍严重程度有关有其一定的理由,但最近的研究表明以上看法并不确实。对心力衰竭病人进行测定时,不能依 Symptoms that limit the activity of patients with heart failure are difficult to assess. The patient’s feeling of shortness of breath varies. The traditional view that patients with heart disease, dyspnea due to elevated left atrial pressure, cardiac output caused by lack of activity caused by fatigue. This simple point of view may be correct for acute heart failure. To be sure, the occurrence of dyspnea and pulmonary edema is indeed associated with left atrial pressure. Drugs that lower left atrial pressure generally relieve dyspnea. The main symptom of clinical syndromes that cause chronic heart failure is ventricular dysfunction. Therefore, physicians speculate that activity may have something to do with the severity of left ventricular dysfunction, but recent research suggests the above is not true. Heart failure patients can not be measured when measured
