The respiratory disorders in various kinds of heart defects were studied in 226 patients with acquired heart defects. The following indices were determined: external respiration, alveolar ventilation, alveolar-capillary diffusion, functional and real intrapulmonary shunts and acid-base state. The complex studies via numerous indices, juxtaposed in the separate defects, revealed various stages of manifestation of the respiratory disorders according to the kind of defect, at identical degree of cardiac insufficiency. The lightest proved to be the respiratory disorders in combined aortic defects and most manifested--in biaxial defects (mitral and aortic). In mitral defects with predominant stenosis, the respiratory disorders are better manifested as compared with those with predominant insufficiency, and for some of the indices--they are considerable.
对226例后天性心脏缺陷患者的各类心脏缺陷所伴发的呼吸紊乱进行了研究。测定了以下指标：外呼吸、肺泡通气、肺泡-毛细血管弥散、功能性和真性肺内分流以及酸碱状态。通过对众多指标进行综合研究，并将其并列于不同的缺陷类型中，发现在相同程度的心功能不全情况下，根据缺陷类型不同，呼吸紊乱表现出不同阶段。结果表明，合并主动脉缺陷时呼吸紊乱最轻，而双轴缺陷（二尖瓣和主动脉）时最为明显。在以狭窄为主的二尖瓣缺陷中，与以关闭不全为主的情况相比，呼吸紊乱表现得更明显，而且就某些指标而言，差异相当大。
