A study was made of pulmonary function tests in patients averaging 2 years post MI, who did not present evidence of chronic bronchitis or other types of primary pneumopathy. The influence of smoking and moderate pulmonary congestion due to heart failure were studied. We found a significant inverse relation between dyspnea and the forced one second expiratory volume, as an expression of bronchial obstruction. There was a significant increase in the respiratory volume in patients after MI. This alteration was particularly evident in patients who smoked. On the contrary, in pulmonary congestion the tendency was towards a decrease in respiratory volume. We confirmed the importance of pulmonary function tests for the evaluation of subjective symptoms, this was confirmed by the finding of a decrease in the dynamic pulmonary volumes, specially in smokers, which demonstrates the unfavorable influence of smoking. Heart failure did not significantly influence static or dynamic parameters, although the residual functional capacity showed a tendency to decrease with the degree of congestion.
对平均在心肌梗死(MI)后2年的患者进行了肺功能测试研究,这些患者没有慢性支气管炎或其他类型原发性肺病的证据。研究了吸烟和心力衰竭引起的中度肺充血的影响。我们发现呼吸困难与作为支气管阻塞表现的用力一秒呼气量之间存在显著的负相关。心肌梗死后患者的呼吸量显著增加。这种改变在吸烟患者中尤为明显。相反,在肺充血时,呼吸量有减少的趋势。我们证实了肺功能测试对评估主观症状的重要性,这一点通过动态肺容量的减少得到了证实,特别是在吸烟者中,这表明了吸烟的不利影响。心力衰竭对静态或动态参数没有显著影响,尽管残余功能能力有随着充血程度而降低的趋势。
