The functional result of aortic valve replacement has been assessed in patients treated for isolated aortic incompetence. Using maximal oxygen uptake as an index of myocardial function, a significant difference (p less than .05) exists between the patients who had Q fever endocarditis on the one hand and those who had bacterial endocarditis or rheumatic fever on the other hand. We believe that permanent myocardial damage occurs as a result of bacterial endocarditis and rheumatic fever but because of the biological properties of Coxiella burnetii the myocardium is spared in Q fever endocarditis.
对单纯主动脉瓣关闭不全患者进行主动脉瓣置换后的功能结果进行了评估。以最大摄氧量作为心肌功能指标，患Q热心内膜炎的患者与患细菌性心内膜炎或风湿热的患者之间存在显著差异（p<0.05）。我们认为，细菌性心内膜炎和风湿热会导致永久性心肌损伤，但由于伯氏考克斯体的生物学特性，Q热心内膜炎患者的心肌得以幸免。
