[Characteristics of the regulation of coronary circulation in progressive disorders of coronary perfusion].
Coronary failure was demonstrated to be followed by impaired coronary circulation regulation in the hypoperfused area, as manifested by quantitative (incomplete realization of dilator reserve) or qualitative (greater coronary resistance) alterations of coronary responses to ischemia. The disorders detected were shown to be directly related to the manifestations of limited coronary flow, predominant with its 70% decrease and represent an essential mechanism of further progression of coronary failure.
