METHOD FOR PREDICTING THE RISK OF DEVELOPING A "NO-REFLOW" PHENOMENON IN PERCUTANEOUS CORONARY INTERVENTIONS IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION WITH ST SEGMENT ELEVATION Russian patent published in 2020 - IPC A61B5/02 G01N33/49 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to X-ray endovascular diagnostics and treatment, cardiology. Clinical anamnestic data are collected: age in years (AGE); time from onset of pain syndrome to revascularization, h, (T), laboratory data – neutrophil count in blood, *10⁹/l, (NEU); blood glucose level, mmol/l, (GL), angiographic data: initial blood flow by TIMI scale: BL=0 – blood flow by TIMI 0-1, BL=1 – blood flow by TIMI 2-3. During the percutaneous coronary intervention, the possibility of performing direct stenting of the infarction-related coronary artery is evaluated: D=0 – it is impossible to perform direct stenting, D=1 – it is possible to perform direct stenting. Presence or absence of the risk of the "no-reflow" phenomenon is determined by the total scoring value of the scorecard values calculated according to the original formulas. If the total score (TOTscore) is equal to or more than 35, the risk of "no-reflow" phenomenon is stated, and if the value is less than 35, "no-reflow" phenomenon development is not predicted.

EFFECT: method enables high-accuracy, rapid and simple prediction of the risk of developing the phenomenon of "no-reflow" in the percutaneous coronary interventions in the patients with acute myocardial infarction with ST segment elevation, which enables timely prevention of this complication.
