Aims: To evaluate diagnostic accuracy of quantitative flow ratio (QFR). A novel method was used for non-invasive functional assessment of intermediate coronary lesions. Fractional flow reserve (FFR) is the gold standard for functional assessment of intermediate lesions.

The OCULUS study aimed to evaluate the effectiveness of the three-dimensional (3D) movie in teaching patients about the consequences of AF and pharmacological stroke prevention.
Methods: The study was based on a questionnaire and included 100 consecutive patients (38% women, 62% with AF history).
Background: The post-cardiac arrest (CA) period is often associated with secondary damage of the brain that leads to severe neurological deficits. The current practice guidelines recommend the use of therapeutic hypothermia (TH) to prevent neurological deficit and improve survival.
Objectives: The aim of the study was to investigate the implementation of medical guidelines in clinical practice and to evaluate the barriers for implementation of TH in cardiology units in Poland.
Background: Coronary artery disease (CAD) and degenerative aortic stenosis often coexist. However, the impact of CAD and its management on the prognosis after transcatheter aortic valve implantation (TAVI) remains uncertain. We sought to evaluate the impact of obstructive CAD, SYNTAX score (Ss), and percutaneous coronary intervention (PCI) prior to TAVI on short-term outcome.

Among platelet indices, mean platelet volume (MPV) has proven to be a valuable predicting factor in cardiac patients. However, platelet distribution width (PDW) is reported to be a more specific marker of platelet reactivity.

Heart team decision supported by different risk score calculations is advisable to estimate the individual procedural risk before TAVI.
Methods: One hundred and fifty-six consecutive patients (n = 156, 48% female, mean age 80.
