Objectives: To evaluate the characteristics and outcomes of patients with a chronic total occlusion (CTO) in a Non-ST Elevation Myocardial Infarction (NSTEMI) cohort.

Background: There is limited data on the clinical characteristics, revascularisation strategies and outcomes of patients presenting with a NSTEMI and a CTO.

Methods: Retrospective analysis of a six-centre percutaneous coronary intervention (PCI) registry in the UK between January 2015 and December 2020 was performed. Patients with a NSTEMI with and without a CTO were compared for baseline characteristics and outcomes.

Results: There were 17,355 NSTEMI patients in total of whom 1813 patients had a CTO (10.4 %). Patients with a CTO were more likely to be older (CTO: 67.8 (±11.5) years vs. no CTO: 67.2 (±12) years, p = 0.04), male (CTO: 81.1 % vs.71.9 %, p < 0.0001) with a greater prevalence of cardiovascular risk factors. All-cause mortality at 30 days: HR 2.63, 95 % CI 1.42-4.84, p = 0.002 and at 1 year: HR: 1.87, 95 % CI 1.25-2.81, p = 0.003 was higher in the CTO cohort. CTO patients who underwent revascularisation were younger (Revascularisation 66.4 [±11.7] years vs. no revascularisation 68.4 [±11.4] years, p = 0.001). Patients with failed CTO revascularisation had lower survival (HR 0.21, 95 % CI 0.10-0.42, p < 0.0001). The mean time to revascularisation was 13.4 days. There was variation in attempt at CTO revascularisation between the 6 centres for (16 % to 100 %) with success rates ranging from 65 to 100 %.

Conclusions: In conclusion, the presence of a CTO in NSTEMI patients undergoing PCI was associated with worse in-hospital and long-term outcomes.

Unlabelled: Problem of the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe during performance of professional, military or official duties and / or living on radiation-contaminated areas, additional exposure not through their own fault but due to a radiation accident, caused the development of a special form of medical expertise as part of the of medical social protection system for suffered contingents in the remote postaccidental period.

Objective: To study and characterize the structure of the survivor categories (clean-up workers and victims) of the Chernobyl Catastrophe in the remote post-accident period (2013-2024) regarding the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe based on the materials of expert cases of the Central Interdepartmental Expert Commission of the Ministry of Health of Ukraine (CIEC).

Material And Methods: The work was performed in the design of a retrospective study that based on analysis of the structure of all categories of Chornobyl NPP accident (ChNPP) survivors during 2008-2024 years and studying of 58,137 medical expert cases, including 19,524 postmortem cases, which were considered by CIEC during 2013-2023 to establish a causal relationship between the disease and influence of radiation exposure and other harmful factors and conditions during ChNPP accident.

Objective: To assess the functional state and age-related characteristics of autophagy in peripheral blood leukocytes as a risk factor for the development of inflammaging using the example of the servicemen of the DefenseForces of Ukraine and clean-up workers of the Chornobyl accident.

Materials And Methods: A total of 103 male patients aged 28-77 (56,48 ∓ 9,05) years were examined. They included: the main group - 23 servicemen of the Defense Forces of Ukraine aged 44-59 (50,21 ∓ 5,13) years; the comparison group - 57 clean-up workers of the Chornobyl accident aged 56-63 (60,31 ∓ 1,78) years; and the control group -23 civilians aged 28-77 (53,26 ∓ 15,98) years.

Fontan-associated liver disease (FALD) may be caused by chronic liver congestion due to high central venous pressure (CVP). Recently, the usefulness of liver native T1 mapping in magnetic resonance imaging (MRI) in adulthood has been reported. To evaluate the usefulness of native liver T1 mapping in children with congenital heart disease (CHD), we investigated the utility of native liver T1 relaxation time (LT1) in pediatric Fontan patients in comparison to other CHDs.
