Proceed from the analysis of coronarographies of patients with cardiac ischemia and cardiac syndrome X, an approximate method is developed to allow cardiologists to find (with satisfactory precision and speed) both changes in the blood flow rate in larger coronary arteries, caused by the appearance of their planar pathological tortuosity, and a hemodynamic significance of those changes based on the data taken from the appropriate coronarographies only. This method is based on replacement of real blood flows in the originally healthy and subsequently pathologically tortuous artery with the corresponding cross-sectionally averaged ones, and subsequent calculation of the blood flow characteristics of interest in terms of the corresponding averaged flow characteristics. It allows one not to take account of a number of identical factors for the originally healthy and subsequently pathologically tortuous segment of the coronary artery under investigation, and gives one the possibility to determine the blood flow parameters of concern at any time after carrying out a coronarography. In addition, the developed method is not associated with solving complicated technical problems, and does not require special facility to be used, special professional training and significant expences. It was successfully tested in laboratory conditions and then successfully applied to appropriate patients.
