RESUMO

Objective: Is to find out which revascularization methods have less of risk factors and complications after the surgery and long-term period. Method(s): From January 2018 to December 2019 were operated 134 patients with LAD CTO. 48 of them underwent MIDCAB: 36 (75%) males and 12 (25%) females;aged 58.7 +/-8.7;7 (14.6%) with previous diabetes;10 (20.8%) with previous PCI of LAD with drug-eluting stent. In the PCI group there were 86 patients: 52 (60.5%) males and 34 (39.5%) females;aged 64.8 +/-8.3;23 (26.7%) with previous diabetes. Result(s): Hospital mortality was 0 (0%) in MIDCAB unlike 1 (1.2%) in PCI. Myocardial infarction was 0 (0%) in both the groups. In MIDCAB the number of conversions to onpump and sternotomy was 0 (0%), there were 6 (12.5%) pleuritis with pleural puncture and 3 (6.2%) with long wound-aches. The hospitalization period was 10.7+/-2.9 days for MIDCAB and 9.9 +/-3.9 days for PCI. In the PCI group 2.0 +/-1.0 drug-eluting stents were used. In-hospital costs were higher for PCI 3809 unlike 3258 for MIDCAB. After one year in MIDCAB group died 2 (4.2%) patients, from noncardiac causes. In PCI group died 3 (3.5%) patients, all from cardiac causes. Because of pandemic COVID-19 were checked only 48 patients by angiography and general clinical examination: 25 after MIDCAB and 23 after PCI. 5 patients have a graft failure, caused by surgical mistakes. 4 patients have stents restenosis and 1 has LAD's reocclusion. Conclusion(s): Both methods of revascularization for LAD CTO are demonstrated similar results. EuroSCORE II (P = 0.008) and glomerular filtrating rate (P = 0.004) are significant potential risk factors for mortality in both groups, age is potential risk factor for graft failure (P = 0.05). Dyslipidemia is significant risk factor for LAD restenosis in PCI group (P = 0.02). MIDCAB is associated with lower incidence of revascularization repeat and in-hospital mortality in the literature data and it costs lower than PCI for LAD CTO as our study has shown.

RESUMO

Cough is a frequent manifestation of COVID-19 (COronaVIrus Disease 2019), therefore, it has an important diagnostic value. There is little information about the characteristics of cough of COVID-19 patients in the literature. To perform a spectral analysis of cough sounds in COVID-19 patients in comparison with induced cough of healthy individuals. Methods. The main group consisted of 218 COVID-19 patients (48.56% - men, 51.44% - women, average age 40.2 (32.4;50.1) years). The comparison group consisted of 60 healthy individuals (50.0% men, 50.0% women, average age 41.7 (31.2;53.0) years) who were induced to cough. Each subject had a cough sound recorded, followed by digital processing using a fast Fourier transform algorithm. The temporal-frequency parameters of cough sounds were evaluated: duration (ms), the ratio of the energy of low and medium frequencies (60 - 600 Hz) to the energy of high frequencies (600 - 6 000 Hz), the frequency of the maximum sound energy (Hz). These parameters were determined in relation to both the entire cough and individual phases of the cough sound. Results. Significant differences were found between some cough parameters in the main group and in the comparison group. The total duration of the coughing act was significantly shorter in patients with COVID-19, in contrast to the induced cough of healthy individuals (T = 342.5 (277.0;394.0) - in the main group;T (c) = 400.5 (359.0;457.0) - in the comparison group;p = 0.0000). In addition, it was found that the cough sounds of COVID-19 patients are dominated by the energy of higher frequencies as compared to the healthy controls (Q = 0.3095 (0.223;0.454) - in the main group;Q (c) = 0.4535 (0.3725;0.619) - in the comparison group;p = 0.0000). The maximum frequency of cough sound energy in the main group was significantly higher than in the comparison group (Fmax = 463.0 (274.0;761.0) - in the main group;Fmax = 347 (253.0;488.0) - in the comparison group;p = 0.0013). At the same time, there were no differences between the frequencies of the maximum energy of cough sound of the individual phases of cough act and the duration of the first phase. Conclusion. The cough of patients with COVID-19 is characterized by a shorter duration and a predominance of high-frequency energy compared to the induced cough of healthy individuals.Copyright © 2022 Budnevsky A.V. et al.
