Air pollution contributes to the premature death of approximately 428,000 citizens of Europe every year. The adverse effects of air pollution can be observed in respiratory, circulatory systems but also in renal function. We decide to investigate the hypothesis indicating that we can observe not only long- but also short-term impact of air pollution on kidney function. We used linear, log-linear, and logistic regression models to assess the association between renal function and NO2, SO2, and PMs. Results are reported as beta (β) coefficients and odds ratios (OR) for an increase in interquartile range (IQR) concentration. 3554 patients (median age 66, men 53.2%) were included into final analysis. Chronic kidney disease (CKD) was diagnosed in 21.5%. The odds of CKD increased with increase in annual concentration of PM2.5 (OR for IQR increase = 1.07; 95% CI 1.01–1.15, P = 0.037) and NO2 (OR for IQR increase = 1.05; 95% CI 1.01–1.10, P = 0.047). The IQR increase in weekly PM2.5 concentration was associated with 2% reduction in expected eGFR (β = 0.02, 95% CI − 0.03; − 0.01). Medium- and short-term exposure to elevated air pollution levels was associated with a decrease in eGFR and development CKD. The main pollutants affecting the kidneys were PM2.5 and NO2.

Left atrial appendage (LAA) occlusion devices have the potential to influence the clinical approach to stroke prevention in patients with atrial fibrillation. A number of percutaneous techniques have been proposed, including various intracardiac plugs and also external ligation. Several devices have been already used in Poland. One of them has been evaluated in randomised controlled trials compared with the current standard of care. Others are less well studied but quite commonly used in Eu-rope. It is anticipated that the use of LAA occlusion technologies in clinical practice will expand. This Consensus Document prepared jointly by Association of Cardiovascular Interventions (AISN) and Heart Rhythm Section (HRS) of Polish Cardiac Society seeks to highlight the critical issues surrounding LAA occlusion therapies and to facilitate the alignment of multiple interests, including those of primary care physicians, general cardiologists and procedural specialists (electrophysiologists and interventional cardiologists) but also other medical professionals. The article summarises current evidence and provides spe-cific recommendations on organisation and conduct of LAA therapy in patients with atrial fibrillation in Poland and defines also operator and institutional requirements fundamental to the establishment of successful LAA occlusion programmme.

Access-site vascular complications in patients undergoing transradial coronary procedures are rare but may have relevant clinical consequences. The aim of the study was to evaluate: (1) radial artery’s (RA) patency immediately after the procedure and in long-term observation, (2) factors influencing the frequency of radial artery’s occlusion (RAO) after percutaneous coronary intervention (PCI) procedures performed via transradial access in the group of 220 patients with acute coronary syndromes (ACS). RA ultrasound was performed 48–72 h after the procedure and in those who were diagnosed with RAO-again after 6–12 months. According to the ultrasonographic findings, the patients were divided into two sub-groups: 187 pts (85 %) with patent RA after PCI and 33 pts (15 %) with RAO. Both sub-groups significantly statistically differed with regard to the frequency of local hematomas—15 versus 27.3 % (p = 0.02), the frequency of applying IIbIIIa inhibitors in PCI—6.4 versus 15.1 % (p = 0.015) and procedure duration—0.59 ± 0.37 versus 0.77 ± 0.38 (p = 0.014), respectively. In a multifactorial analysis the only factor influencing RA patency promptly after the procedure was PCI duration (p < 0.05, r = −0.22). In the follow-up, right RA remained still obstructed in 28 patients (12.7 %) whereas in five patients (2.3 %) the regular flow in RA was resumed. The chronic RAO was clinically silent. Due to insignificant frequency of the occurrence of RAO after PCI procedure in patients with ACS as well as practically lack of clinical consequences of this artery’s occlusion in long-term observation, we do not see any implications to routine ultrasound periprocedural RA evaluation.
