Relevance. The ability of patient to recover following coronary artery bypass grafting (CABG) is denoted by the term “rehabilitation potential” (RP). RP is crucial for arranging further referrals and developing of tailored rehabilitation program, which would comply with patient’s needs and capabilities to the greatest possible extent. Use of rehabilitation potential in routine medical practice is impeded by lack of commonly accepted definition and plausible set of assessment criteria. Objective. To determine parameters from those available to rehabilitation center physician at initial evaluation that are most representative of patient RP in phase II of rehabilitation following CABG. Materials and Methods. 703 discharge summaries and 450 inpatient medical charts of patients in cardiorehabilitation phase II were analyzed. Information that was present in ≥ 95 % of discharge summaries of a given patient was considered available information. Multifactor analysis was conducted to obtain impact level values for the parameters that influence the outcome of cardiorehabilitation phase II and are available at initial patient evaluation. Results. Patient RP is mainly determined by the level of daily physical activity before surgery, target level of physical activity achieved in phase I of rehabilitation, patient’s age, body mass index, severity of concomitant disorders and post-surgery complications, hemoglobin level, treatment adherence, history of myocardial infarction, diagnosed hypertensive heart disease and diagnosed chronic heart failure. Conclusion. Rehabilitation potential in patients in phase II of cardiorehabilitation following CABG can be assessed by 11 parameters with the highest levels of impact on rehabilitation outcome available to the physician at initial patient evaluation.
