Background and Goal of Study – non-cardiac surgery is assosiated with up to 1,5 % mortality rate and near 40 % of these are caused by cardiac complication (ESC/ESA Guidelines). The goal of study was to analise impact of multiple factors that can be assossiated with lethal prognosis in patients with cardiac pathology.
Materials and Methods. We have included 172 patients with documented cardiac pathology undergoing noncardiac surgery. Exclusion criterious were oncology, thraumatic injury and urgent surgery. We have analised surgical risk (SR) according to type of surgery, functional capacity (FC) of the patient, clinical risc factors (CRF) according to revised cardiac risk index (RCRI), ASA physical status, level of natriuretic peptide (NUP) before surgery and hs-troponins (hsTr) in patients with elevated NUP, myocardial performance index or Teiindex as combined marker of systolic and dyastolic
heart function assessed with heart sonography Results. 56 (32.56 %) patients had elevated NUP before surgery. 32 persons (18.61 %) among all died. But 28 deceased had an increased level of NUP. That is, half of patients with elevated NUP died. The average time of death was 30 days after surgery.
It should be noted that the level of troponins in the dynamics did not exceed the norm in any person with the initial elevation of NUP. In 4 persons without initial elevation of NUP the single jump of hsTr just after the surgery was revealed. Two of them had short clinical postoperative anginal symptoms but there was no changes on ECG or heart sonography. No peculiarities among SR, CRF was found. 20 patients (62.5 %) among deseased persons had ASA III status. Functional capacity turned out to be interesting – it was poor in 36 patients (20.93 %), and 28 among them died. The MPI, which according to the published data should be within 0.39±0,05 in norm, was significantly higher in all our patients – 0.60±0.09 (p˂0.05), that identified combined systolic and diastolic myocardial dysfunction. And, contrary to our expectations, MPI was 0.56±0.08 in those who died.
Conclusions. The results of our observation confirm the feasibility of determining the level of NUP in patients with concomitant cardiac pathology. Particular attention among them should be paid to persons with reduced functional capacity and higher class in the ASA physical status. Assessing of natriuretic peptide and/or troponins dynamic require some financial costs, while functional capacity assessment is an affordable clinical method that we should use more widely in routine practice to identify patients with increased cardiac risk.

Abstract. Rehabilitation of patients following an acute myocardial infarction remains one of the most urgent tasks of modern cardiology. Cardiac rehabilitation programs are aimed not only at improving the functioning of the cardiovascular system but also at ensuring the mental health of patients, restoring their working capacity, and returning to a full-quality life as soon as possible. Patients receive many benefits of cardiac rehabilitation from physical training. The main type of physical exercise in patients with cardiovascular diseases is aerobic training, which increases maximal oxygen consumption and improves cardiorespiratory endurance. The dosed training method is the basis of the development of the patient's functional adaptation to physical exertion in cardiovascular diseases. The objective was to develop and test the effectiveness of the physical therapy method proposed by the authors for the recovery of patients with acute myocardial infarction after stenting. Material and methods: clinical (standard) examination and interview of the patient, medical history, blood pressure (BP) and heart rate (HR) measurement, pulse oximetry with saturation (SpO2) determination, orthostatic test, 10-meter walk test (10MWT), the Timed Up and Go test (TUG), the 6 Minute Walk Test (6MWT). 16 patients were enrolled in the study which lasted 5 weeks. Sessions according to the developed methodology of physical therapy were conducted with each patient for 12 days. Inclusion criteria: age between 50-80 years old, medical diagnosis: myocardial infarction, after stenting, no contraindications to cardiac rehabilitation. The effectiveness of the developed method of physical therapy for the recovery of patients with acute myocardial infarction after stenting was assessed. Changes in the performance of 10MWT, 6MWT, and TUG tests indicated improved adaptation and tolerance of the respiratory and cardiovascular systems to exercise, as well as normalization of blood pressure, heart rate, and SpO2. Conclusions. Physical exercises, according to the developed program of physical therapy, improve the general physical condition of patients, increase their functional capabilities, improve indicators of cardiovascular and respiratory system and have a positive effect on life quality. The study confirmed the importance of physical therapy in the recovery of patients with acute myocardial infarction after stenting.

Abstract.

Introduction. Functional capacity is important parameter of activity of a person. It can be assessed with different methods, including interviewing, walk tests, cardiopulmonary exercise testing. According to the recommendations of the European Society of Cardiology, the assessment of functional capacity is an important step in the perioperative management of a patient with concomitant cardiovascular pathology during non-cardiac surgery. Purpose of our study was to implement assessing of functional capacity in clinical practice, including perioperative management of patients. And also, to compare the practical value of self-reported methods of assessing functional capacity and exercise testing. Materials and methods. 15 healthy men aged 33±5.4 years and 172 patients with documented pathology of the cardiovascular system aged 65±2.8 years were included in the study, among them 51% were male. We compared the value of different methods and the expediency of assessing the functional capacity of a patient with concomitant pathology of the cardiovascular system before planned non-cardiac surgery. Results. All healthy individuals gave a positive answer to the question about ability to climb two flights of stairs. The average Duke Activity Status Index score was 52.47±5.96, which corresponded to the calculated value of METs 9.19±0.73. During cardiopulmonary exercise testing, the average value of VO₂max in these individuals was 47.56±11.34 mL/(kg·min). A direct strong correlation between Duke Activity Status Index values and VO₂max was established (r=0.91, р˂0.01). 36 patients (21%) reported inability to climb two flights of stairs added. The average DASI in these persons was 12.84±4.38 and the level of NTproBNP was 1116±75. On the contrary in the rest of the patients the DASI was 28.18±7.72 and NTproBNP 302±42 with statistically significant difference (p˂0.01). The dynamics of troponins in the examined subjects did not show any increase in the postoperative period. The values of the EF in patients reported inability to climb two flights were lower by 9.78% compared with others (56.57±12.34% and 62.71±6.35%, p˂0.01). The average number of days spent in the hospital was 22 in patients with inability to climb two flights and 12 in the rest. 32 patients (19%) died, 28 deceased belonged to the group with inability to climb two flights of stairs. The average time of death was 29.86 days. Correlation analysis revealed a direct relationship of average strength between the Duke Activity Status Index and EF (0.42, p 0.007), an inverse relationship of average strength between the Duke Activity Status Index and NTproBNP (-0.42, p=0.01) and the number of days spent in a hospital (-0.39, p=0.005). In conclusion we found that healthy men with an active lifestyle have higher average VO₂max parameters and confirmed that the VO₂max obtained during the cardiopulmonary exercise testing was comparable to questionnaire methods for assessing functional capacity. One fifth of patients with confirmed cardiovascular pathology self-reported inability to climb two flights of stairs. These individuals had a lower EF, a higher concentration of NTproBNP, a longer stay in the hospital, and significantly higher mortality. the Duke Activity Status Index correlates with left ventricular systolic function and NTproBNP level.

Abstract.
Non-thyroidal illness syndrome (NTIS) also known as euthyroid sick syndrome or low T3 syndrome is hypothyroidism caused by peripheral changes in the metabolism and thyroid hormone transport caused by severe debilitating diseases, in particular, heart failure. Recent data indicate that chronic heart failure can result in thyroid hormone metabolism disruption, which contributes to a progressive decrease in the concentration of triiodothyronine. The objective was to evaluate the effectiveness and safety of hormone replacement therapy with low doses of thyroxine in congestive heart failure in patients with low triiodothyronine syndrome. The levels of thyroid-stimulating hormone, thyroxine-binding globulin, free thyroxine, total triiodothyronine, free triiodothyronine, and reversible triiodothyronine were measured by radioimmunological assay from samples obtained from 56 patients with chronic heart failure and 19 practically healthy individuals of the control group matched by age, gender, and body mass index. Patients with low triiodothyronine syndrome were prescribed hormone replacement therapy with low doses of thyroid hormones (thyroxine 12.5-25 mcg/day) until the euthyroid state was achieved. The values of total and free triiodothyronine were significantly lower in patients with heart failure, the level of thyroxine- binding globulin was also reduced, more than twofold increase in reversible triiodothyronine level was demonstrated compared to controls. Low triiodothyronine syndrome was diagnosed in 33.9% of patients with heart failure. Hormone replacement therapy resulted in a slight improvement in contractile function in individuals with low triiodothyronine levels, 2 (10.5%) patients manifested with signs of hyperthyroidism. Advanced stages of heart failure might be linked with NTIS. Hormone replacement therapy with low doses of thyroxine can contribute to a moderate improvement in contractile function, as evidenced by the improvement in left ventricular ejection fraction.
