08 in CLI and -0.15 in non-CLI; P = 0.01). The larger baseline intima-media (IMT) in the CLI group allowed to predict a greater number of reintervention (P = 0.01) and major adverse event rates (P = 0.03). CLI patients presented larger decrease in the Rutherford scale compared to non-CLI (P < 0.001).

Baseline IMT was predictive for re-interventions and major adverse event rates. Although neither of groups exhibited significant changes in endothelial function, we proved differences between them regarding to changes in RHI.

According to the European Society of Cardiology guidelines, self-care is a key part of treatment for patients with heart failure. A large evidence base has been accumulated regarding the direct impact of self-care on the outcome of patients with heart failure. In order to assess self-care in patients with heart failure and to evaluate the effectiveness of the interventions taken, a reliable and culturally acceptable instrument is required. The Revised Self-care of Heart Failure Index (SCHFI) is a new tool for assessing self-care in patients with heart failure.

Our aim was to test the reliability of the Polish version of the Revised SCHFI.

The standard forward-backward translation procedure was used to translate the Revised SCHFI questionnaire into Polish. selleck chemicals llc The reliability of the SCHFI was assessed based on Cronbach's α, item-total correlation, exploratory factor analysis, and confirmatory factor analysis.

A total of 127 patients with heart failure (mean [SD] age, 68.5 [11.2] years) completed the questionnaire. The mean (SD) total self-care score in the study group was 51.92 (22.0). Patients scored the highest in terms of self-care confidence (mean [SD] score, 65.63 [21.0] points), and the lowest in symptom perception (mean [SD] score, 54.64 [18.28] points). The Revised SCHFI had satisfactory psychometric properties in all subscales (self-care maintenance α = 0.790, symptom perception α = 0.790, self-care management α = 0.705).

The Polish version of the Revised SCHFI is a reliable and valid instrument for assessing self-care level in heart failure patients.

Fibrin accumulation within the stenotic leaflets associated with impaired fibrinolysis was observed in severe aortic stenosis (AS). Little is known about fibrin clot properties in patients scheduled for transcatheter aortic valve implantation (TAVI).

We investigated whether TAVI patients display a more prothrombotic state, including suppressed fibrinolytic capacity compared to those undergoing surgery.

We enrolled patients with advanced AS without significant atherosclerotic vascular disease scheduled for TAVI (n = 45) or surgical aortic valve replacement (SAVR, n = 59). Plasma fibrin clot features, including clot permeability (Ks) reflecting an average pore size, and lysis potential (Lys50), along with thrombin generation were determined off anticoagulation within 12 hours before the procedure.

TAVI patients compared to SAVR had prolonged Lys50 (median 420 [interquartile range, 337-480] vs 379 [337-428] s, P = 0.045) and formed denser clots, reflected by lower Ks (3.66 [3.05-4.84] vs 4.36 [3.6-5.27] increased thromboembolic risk following TAVI.
Transesophageal echocardiography (TEE) allows detailed characterization of atrial fibrillation (AF) substrate and could be valuable for predicting pulmonary vein isolation (PVI) procedure outcomes.

We aimed to assess the value of TEE-derived left atrial (LA) and LA appendage (LAA) features as prognostic markers for AF recurrence after cryoballoon-based ablation.

Patients were enrolled using prospective database of consecutive PVI procedures performed over a 7-year period. Following TEE-derived parameters were investigated LAA emptying flow velocity (LAA-FV), presence of patent foramen ovale (PFO), LA spontaneous echo contrast and mitral regurgitation. Diagnosis of AF recurrence was based on scheduled and symptoms triggered ECG monitoring. Cox's regression model and Kaplan-Meier survival curves were applied for statistical analysis.

A total of 417 consecutive patients who underwent their first PVI using cryoballoon were analysed (mean age 59 years). AF recurrence was noted in 25.7 % of patients (median in planning the ablation strategy.
In the current pandemic, Health Care Workers (HCWs) are at a high risk of developing COVID-19. Preventive methods like the use of personal protective equipment, isolation, social distancing, and chemoprophylaxis show limited benefit. Despite standard prophylaxis, many of the HCWs develop COVID-19. Medical ozone therapy has immunomodulatory, antioxidant and antiviral effect, and, therefore, it can be explored as prophylaxis for COVID-19.

We conducted a retrospective controlled cohort study. IV ozonized saline was administered once a day for a total of 4 days in one month in addition to standard prophylaxis for COVID-19 to HCWs in a dedicated COVID hospital. Fresh ozonized saline was prepared for every administration and was given over 1 hour.

There were 235 HCWs, 64 received the ozone prophylaxis and 171 did not. The incidence of COVID-19 was significantly (p=0.04) lesser in HCWs that received ozone prophylaxis (4.6%) as compared to those who did not (14.03%). The benefit was seen irrespective of the risk of exposure. In the red zone, 8.69% of the HCWs who received ozone prophylaxis tested positive as opposed to 15.3% of those who did not. In the orange zone, 4.34% of the HCWs who received ozone prophylaxis tested positive, remarkably lesser than those who did not (20%). In the green zone, none of the HCWs who received ozone prophylaxis tested positive; however, 3.4% of the HCWs who did not receive ozone prophylaxis tested positive. No major adverse events were noted.

IV ozonized saline can be used in addition to the standard prophylactic regimen for the prevention of COVID-19 in HCWs. Prospective larger studies are required to establish the potency of IV ozonized saline as prophylaxis.
