Dyspnea is a common symptom of heart failure frequently relied upon to assess clinical functioning. The purpose of this study is to explore a broad range of medical, psychological, and social factors that correlate with dyspnea in heart failure patients. Seventy-six participants ranged from well-compensated, ambulatory subjects to those with recent hospitalization for acutely decompensated heart failure. The sample was predominantly male, mean age of 63.5 years, with mild depressive symptoms in 25%. Correlation analysis revealed that dyspnea significantly correlated with depression, fatigue, and overall health perception. Standard regression analyses indicated that depression, fatigue, and overall health perception uniquely contributed to dyspnea, explaining 38.0% of the total variance. The present study confirms that dyspnea is multifactorial, with links to psychological distress and overall health perception.
呼吸困难是心力衰竭的常见症状，常被用于评估临床功能。本研究的目的是探讨与心力衰竭患者呼吸困难相关的广泛医学、心理和社会因素。76名参与者涵盖了代偿良好、可走动的受试者至近期因急性失代偿性心力衰竭住院的患者。样本以男性为主，平均年龄63.5岁，25%有轻度抑郁症状。相关性分析显示，呼吸困难与抑郁、疲劳和总体健康感知显著相关。标准回归分析表明，抑郁、疲劳和总体健康感知对呼吸困难有独特影响，解释了总方差的38.0%。本研究证实，呼吸困难是多因素的，与心理困扰和总体健康感知有关。
