[Predicting the results of rehabilitation treatment of patients with acute myocardial infarction who underwent coronary artery stenting: focus on the rehabilitation potential].

The search for ways to assess the rehabilitation potential (RP) in patients with acute myocardial infarction (AMI) who have undergone stenting remains relevant, which will allow personalizing approaches to prescribing treatment complexes necessary for a particular patient, increasing their effectiveness and reducing the likelihood of complications.

Objective: To develop a method for assessing RP in patients in the acute period of myocardial infarction and to evaluate its role in predicting the effectiveness of therapeutic measures in the early recovery period.

Material and methods: The study consisted of two parts. In the first part, a method for assessing the RP of patients with AMI was created using mathematical modeling methods. For this purpose, the analysis of discharge epicrisis of 137 patients (training sample) with AMI aged from 34 to 85 years (average age 59.4±2.1 years) was carried out. In the second part of the study, the results of rehabilitation measures were analyzed in these patients who, after the intensive care unit and intensive care unit, were transferred to the cardiology department of Angara Clinical Resort JSC. At the end of the II stage of rehabilitation, a multidisciplinary team evaluated the effectiveness of treatment of patients using integral indicators characterizing the clinical condition of a patient who has undergone acute coronary syndrome and stenting.

Results: In the first part of the study, devoted to the development of a mathematical model for assessing the RP of patients with AMI, an algorithm of methodology was created: a formalized patient map was formed, the evidence base was represented by 109 indicators; certain indicators were assigned the values of coefficients of linear classification functions, depending on which the patient fell into one of three groups: group 1 - high RP; group 2 - medium RP; group 3 - low RP. The second part of the study was devoted to determining the value of RP for predicting the effectiveness of therapeutic measures in the early recovery period (stage II of medical rehabilitation). When testing patients at the end of treatment at the resort, it was found that the greatest effect was observed in group 1 patients with high RP. A lesser effect was observed in patients of group 2 and, especially, group 3.

Conclusion: The use of a method for assessing RP based on mathematical modeling in AMI patients who have undergone stenting allows predicting the results of medical rehabilitation of patients at stage II in the conditions of the resort.
