Long-term outcomes following drug-eluting balloon or thin-strut drug-eluting stents for treatment of in-stent restenosis stratified by duration of dual antiplatelet therapy (DEB-Dragon Registry).

Introduction: Data regarding the duration of dual antiplatelet therapy (DAPT) in patients with drug-eluting stent restenosis (DES-ISR) treated with percutaneous coronary intervention (PCI) and drug-eluting balloons (DEB) or DES are not unambiguous.

Aim: To evaluate the relationship between long-term outcomes and the length of DAPT in patients treated with PCI due to DES-ISR with DEB or DES.

Material And Methods: Overall, a total of 1,367 consecutive patients with DES-ISR, who underwent PCI with DEB or DES between 2008 and 2019 entered the study.

Frequency and predictors of diagnostic coronary angiography and percutaneous coronary intervention related to stroke.

Background: Stroke related to percutaneous coronary interventions (PCIs) is an infrequent complication, which can be potentially life-threatening and can lead to serious disability.

Aims: This study aimed to assess the relationship between the type of coronary procedure and incidence of stroke, as well as its predictors.

Methods: This retrospective analysis was performed on prospectively collected data gathered in the Polish National Registry of Percutaneous Coronary Interventions (ORPKI) between January 2014 and December 2019 and included 1177 161 coronary procedures.

Long-Term Prognostic Significance of High-Sensitive Troponin I Increase during Hospital Stay in Patients with Acute Myocardial Infarction and Non-Obstructive Coronary Arteries.

A topic already widely investigated is the negative prognostic value regarding the extent of high sensitive troponin I (hs-TnI) increases among patients with myocardial infarction (MI) and obstructive coronary atherosclerosis compared to a group of patients with MI and non-obstructive coronary atherosclerosis (MINOCA). Thus, the aim of this study was to evaluate the prognostic value concerning the extent of hs-TnI increase on clinical outcomes among patients with a MINOCA working diagnosis. We selected 337 consecutive patients admitted to hospital with a working diagnosis of MINOCA.

Effect of day- and night-time admissions on long-term clinical outcomes of patients with acute myocardial infarction treated with percutaneous coronary intervention.

Introduction: It has been suggested that the time of admission during the day and night may influence the clinical outcomes of patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI).

Objectives: The aim of this study was to assess the impact of day- and night‑time admissions on the clinical outcomes of patients with AMI undergoing PCI.

Patients And Methods: This retrospective cohort study was based on the data on PCIs performed in Poland from January 2014 to December 2017, prospectively collected in the National Registry of Invasive Cardiology Procedures (ORPKI).

The relationship between increased air pollution expressed as PM concentration and the frequency of percutaneous coronary interventions in patients with acute coronary syndromes-a seasonal differences.

The aim of the presented study was to assess the relationship between air pollution expressed as particulate air matters less than 10 μm (PM) and acute coronary syndromes (ACSs). In this observational study, we selected regions with low pollution according to PM (non-polluted) and with the highest pollution (polluted). The occurrence of percutaneous coronary interventions (PCIs) in patients with ACSs was matched according to the location.

Age and gender differences in clinical outcomes of patients with heavy-calcified coronary artery lesions treated percutaneously with rotational atherectomy.

Background: Rotational atherectomy (RA) used in elderly patients treated with percutaneous coronary interventions (PCI) could enable revascularization or the omission of cardiac surgery. Knowledge about factors affecting the prognosis may improve the results of treatment.

Objectives: We aimed to assess the relationship of gender and age with long-term clinical outcomes expressed as major adverse cardiac and cerebrovascular events (MACCEs).

Association between the mortality rate and operator volume in patients undergoing emergency or elective percutaneous coronary interventions.

Background: Previous studies have suggested that low operator and institutional volume may be associated with an increased risk of adverse events in patients undergoing percutaneous coronary intervention (PCI).

Aims: The aim of the study was to assess the relationship between operator volume and procedure- -related mortality in the emergent and elective settings.

Methods: Data were obtained from a national registry of PCIs, maintained in cooperation with the Association of Cardiovascular Interventions of the Polish Cardiac Society.
