METHOD FOR EARLY IDENTIFICATION OF RISK OF DEVELOPING IMPAIRED GLUCOSE TOLERANCE IN PATIENTS WITH STABLE EFFORT ANGINA WITH UNDERLYING ADMINISTERING BETA-ADRENERGIC BLOCKING AGENTS WITH NO ADDITIONAL VASODILATING PROPERTIES Russian patent published in 2014 - IPC A61B5/402 A61B5/15 A61K31/138 A61K31/7004 A61P9/10 A61P43/00 G01N33/50 

FIELD: medicine.

SUBSTANCE: invention can be used to identify a high risk of developing impaired glucose tolerance in patients with stable effort angina with underlying administering beta-adrenergic blocking agents with no additional vasodilating properties. Therapy is preceded by conducting 2 exercise tests on the same day to achieve a threshold load power according to the same protocol, initially and 2 hours after administering a single dose of the beta-adrenergic blocking agents. If observing an interval gain of 120 seconds and more from the beginning of the load to the angina attack and/or reduction of an ischemic ST segment on the electrocardiogram not less than 1 mm at the 2nd load as compared to the 1st load, a risk of impaired glucose tolerance is considered to be high. A glucose tolerance test is carried out in these patients 4-5 weeks after the scheduled administration of the beta-adrenergic blocking agents. If impaired glucose tolerance is detected, administering the beta-adrenergic blocking agents is withdrawn. If the 2nd load as compared to the 1st load shows an interval to the angina attack and/or reduction of the ischemic ST segment on the electrocardiogram at a depth not less than 1 mm increasing less than by 120 seconds, a risk of developing impaired glucose tolerance is considered to be negligible. Treatment of these patients with the beta-adrenergic blocking agents is continued without the glucose tolerance test required.

EFFECT: method provides preventing carbohydrate metabolic disorders by the early identification of the high risk of developing impaired glucose tolerance in the given patients by detecting a compensatory increase of the glucose consumption with insulin resistance and a lower availability of free fatty acids to provide myocardial energy needs.
