Limitation of coronary perfusion of different degree induces inhomogeneous changes in resistance of vessels in the hypoperfusing zone: an adequate dilatory regulatory reaction may be followed by an increase in resistance of the coronary vessels. An active component of diastolic coronary resistance used to analyze vascular reactions, rate and character of changes in resistance under conditions of coronary perfusion as well as histological and electron-microscopic estimation of the vascular wall state testify to reversibility and active character of the observed changes in coronary resistance including its increase. This increase is pathogenetically significant as it may induce further development of the coronary perfusion disorder.
在充分的扩张调节反应之后，冠状动脉阻力可能会增加。用于分析血管反应的舒张期冠状动脉阻力的活性成分、冠状动脉灌注条件下阻力变化的速率和特征，以及血管壁状态的组织学和电子显微镜评估，都证明了观察到的冠状动脉阻力变化（包括其增加）的可逆性和活性特征。这种增加在发病机制上具有重要意义，因为它可能会导致冠状动脉灌注障碍的进一步发展。
