The search for methods to assess the rehabilitation potential (RP) of patients with ischemic heart disease (IHD) who underwent coronary artery bypass surgery (CABS), which will allow to personalize approaches to the administration of necessary for the certain patient treatment complexes, increasing their effectiveness and reducing the probability of complications, remains relevant.
OBJECTIVE
To develop a method for RP evaluation in patients with IHD who underwent CABS and to assess its role in predicting the effectiveness of therapeutic activities in the early rehabilitation period.
MATERIAL AND METHODS
The study consisted of two parts. A method for RP assessment in 118 patients with IHD aged 36—85 years (mean age 62.3±2.0 years) who underwent CABS was developed in the 1st part based on the analysis of hospital discharge reports using mathematical modeling methods. The results of rehabilitation activities were analyzed in the 2nd part of the study in patients who were transferred to the cardiovascular department of the Angara Clinical Resort after the cardiovascular surgery department for the second stage of rehabilitation. The multidisciplinary team evaluated the effectiveness of patients’ treatment after the rehabilitation completion using integral indicators characterizing clinical condition of the patient who underwent CABS.
RESULTS
A methodological algorithm was created in the 1st part of the study, namely a formalized patient chart was formed, the evidence base was represented by 99 indicators. The values of linear classification functions’ coefficients were assigned to certain indicators, according to which the patient was classified into one of four groups: the 1st group — without RP; the 2nd group — with medium RP; the 3rd group — with high RP and the 4th group — with low RP. The values of RP were determined in the second part of the study for predicting the effectiveness of therapeutic measures in the early rehabilitation period (the second stage of medical rehabilitation). It has been found that the greatest effect was observed in subjects of the 3rd group with high RP in the patients’ testing after treatment at the health resort. The lesser effect has been noted in patients of the 2nd group and especially of the 4th group.
CONCLUSIONS
The use of RP assessment method based on mathematical modeling in patients who underwent CABS allows to predict the results of patients’ medical rehabilitation at the second stage in the health resort conditions.
