Introduction: Some patients with coronary heart disease are diagnosed with severe aortic stenosis. For further treatment, coronary angiography is performed in these patients. For intermediate lesions, obtaining coronary artery physiological data can facilitate clinical decision-making regarding revascularization.

Using a mutant form of a DNA polymerase enables tracking its signature in the replicated DNA. Here, we used the allele encoding the catalytic subunit of Pol ε to analyse its contribution to DNA replication in yeast with the allele of an essential gene encoding a subunit of the GINS complex.

Aim: To assess the relationship between operator experience and procedural outcomes of patients treated with PCI and rotational atherectomy (RA).
Methods: Data for conducting the current analysis were obtained from the national registry of percutaneous coronary interventions (ORPKI) maintained in cooperation with the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society.
DNA replication is performed by replisome proteins, which are highly conserved from yeast to humans. The CMG [Cdc45-Mcm2-7-GINS(Psf1-3, Sld5)] helicase unwinds the double helix to separate the leading and lagging DNA strands, which are replicated by the specialized DNA polymerases epsilon (Pol ε) and delta (Pol δ), respectively. This division of labor was confirmed by both genetic analyses and in vitro studies.

Aims: The aim of the study was to evaluate the trends in the percentage of sexes in the subsequent years, to compare demographic characteristics between men and women, and to identify factors associated with the risk of periprocedural complications and death.
Methods: We analyzed data on 751 113 patients treated with PCI between 2014 and 2020 from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI).
