DIAGNOSTIC TECHNIQUE FOR DIABETIC CARDIOVASCULAR AUTONOMOUS NEUROPATHY IN FEMALES SUFFERING FROM TYPE 2 DIABETES MELLITUS BY MEANS OF CONTINUOUS-WAVE DOPPLER ULTRASOUND OF MICROVASCULATURE Russian patent published in 2015 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: microvasculature is assessed by continuous-wave Doppler ultrasound. The Minimax-Doppler K apparatus measures linear blood flow velocities initially and with functional test of reactive hyperaemia, and a percentage of a peak coetaneous blood flow gain and an arteriolar blood flow reduction. That is followed by assessing the functional state of vegetative regulation of the cardiac rhythm by isolating 3 degrees of severity of cardiovascular neuropathy. A mild degree is shown by the peak coetaneous blood flow gain of less than 10%, the 8-minute arteriolar blood flow reduction of less than 15%. A moderate degree of severity is accompanied by the peak coetaneous blood flow gain of more than 10%, and the 8-minute arteriolar blood flow reduction of less than 15%. Severe cardiovascular neuropathy is stated if observing the peak coetaneous blood flow gain of less than 10%, the 8-minute arteriolar blood flow reduction of less than 15%.

EFFECT: technique enables early diagnosing of diabetic cardiac neuropathy, assessing its severity for the purpose of determining the therapeutic approach and working capacity examination.
