A study of 45 patients with chronic obstructive bronchitis by the method of radionuclide ventriculography with 99mTc showed that even the early stages of the disease were characterized by an inhibition of the contractile function of the left cardiac ventricle. With progression of respiratory insufficiency, maintaining of the left cardiac ventricle stroke volume is achieved by increase of the final-diastolic and final-systolic volumes. Appearance of signs of cardiac decompensation is accompanied by a breakdown of this compensatory mechanism accompanied by a reduction of the strike volume and diminished rate of contraction of the circular fibers of the left ventricle myocardium.
一项采用99mTc放射性核素心室造影法对45例慢性阻塞性支气管炎患者进行的研究表明，即使在疾病的早期阶段，左心室的收缩功能也受到抑制。随着呼吸功能不全的进展，左心室的每搏输出量通过舒张末期和收缩末期容积的增加得以维持。心脏代偿失调迹象的出现伴随着这种代偿机制的崩溃，随之而来的是每搏输出量的减少以及左心室心肌环形纤维收缩速率的降低。
