EARLY SCREENING DIAGNOSTIC TECHNIQUE FOR HUMORAL TRANSPLANTED HEART REJECTION Russian patent published in 2015 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: common carotid artery (CCA) is scanned. A peak systolic blood flow velocity in the CCA and the beginning of the systolic peak to peak time, a final diastolic blood flow velocity in the CCA, systolic and diastolic CCA diameters are determined. The value K is determined by formula K=(Vs-Vd)·Dd²:[AT·(Dd²-Ds²)], wherein Vs, Vd is the peak systolic and final diastolic blood flow velocities in the CCA respectively, cm/s; Ds, Dd are systolic and diastolic CCA diameters, cm; AT is the time from the beginning of the systolic peak blood flow to its peak, s. If the value K is more than 8,500, the humoral transplanted heart rejection is diagnosed.

EFFECT: method enables increasing the early diagnostic accuracy of the humoral heart rejection by assessing the reliable diagnostic value that is a hardness of the vascular wall of the common carotid artery, and avoiding the invasive diagnostic intervention.
