Patients with heart failure and reduced ejection fraction: A sub-analysis from the 3-year Coordinated Myocardial Infarction Care Program (KOS-MI) registry.

Background: The Coordinated Care Program after Myocardial Infarction (KOS-MI) implemented in Poland has shown significant improvement in patient prognosis, ended in nationwide success, and got international attention. A similar program and methodology may be an attractive option for patients with heart failure (HF).

Aims: This study aimed to analyze whether a similarly structured program would also be beneficial for HF patients after myocardial infarction.

Long-term outcomes of the Coordinated Care Program in Patients after Myocardial Infarction (KOS-MI).

Background: The Coordinated Care in Myocardial Infarction Program (KOS-MI) was introduced to improve prognosis for patients after myocardial infarction (MI). The program includes complete revascularization followed by unrestricted access to rehabilitation, electrotherapy, and cardiac care.

Aim: This study aimed to assess major adverse cardiac and cerebrovascular events (MACCE) of patients enrolled in the KOS-MI at 3-year follow-up.

Safety and feasibility of minimally invasive coronary artery bypass surgery early after drug-eluting stent implantation due to acute coronary syndrome.

Background: The evidence on performing minimally invasive coronary artery surgery early after drug-eluting stent (DES) implantation due to acute coronary syndrome (ACS) is limited.

Aim: The study aimed to determine the safety and feasibility of this approach.

Methods: This registry included 115 (78% male) patients treated from 2013 to 2018, who underwent non-left anterior descending (LAD) percutaneous coronary intervention (PCI) due to ACS with contemporary DES implantation (39% diagnosed with myocardial infarction at baseline), followed by endoscopic atraumatic coronary artery bypass (EACAB) surgery within 180 days, after temporary P2Y12 inhibitor discontinuation.

Temporal, biomechanical evaluation of a novel, transcatheter polymeric aortic valve in ovine aortic banding model.

Objectives: The aim of the study is to evaluate the functionality, durability, and temporal biocompatibility of a novel, balloon-expandable polymeric transcatheter heart valve (ATHV) system (InFlow, CardValve Consortium, Poland). Along with expanding TAVI indications, the demand for new transcatheter valves is increasing.

Methods: A surgical ascending aortic banding model was created in 20 sheep.

Incidence and course of acute coronary syndrome cases after the first wave of the COVID-19 pandemic.

Background: The collateral damage caused by the COVID-19 pandemic affected cardiovascular disease patients, mainly acute coronary syndrome (ACS) cases. Additionally, lockdown caused treatment-related concerns and reluctance to seek medical help, factors that can delay treatment.

Aim: We aimed to analyze the incidence and course of ACS after the first COVID-19 wave.

One-stage hybrid coronary revascularization for the treatment of multivessel coronary artery disease- Periprocedural and long-term results from the "HYBRID-COR" feasibility study.

Background: The constant growth of interest in hybrid coronary artery revascularization (HCR) is apparent. Yet, few studies report outcomes of the one-stage HCR. Consequently, the status of such procedures is not adequately supported in clinical guidelines.

The impact of first wave of the SARS-CoV-2 2019 pandemic in Poland on characteristics and outcomes of patients hospitalized due to stable coronary artery disease.

Background: An investigation of baseline characteristics, treatment, and outcomes in patients with stable coronary disease after the first wave of the severe acute respiratory syndrome coronavirus 2 (SARS- -CoV-2) pandemic may provide valuable data and is beneficial for public health strategy in upcoming years.

Methods: A multi-institutional registry, including 10 cardiology departments, was searched for patients admitted from June 2020 to October 2020. The baseline characteristics (age, gender, symptoms, comorbidities), treatment (non-invasive, invasive, surgical), and hospitalization outcome (mortality, myocardial infarction, stroke, composite endpoint - major adverse cardiac and cerebrovascular events [MACCE]) were evaluated.

6-Month Evaluation of a Transcatheter Aortic Valve (Myval) in a Novel Ovine, Supra-Aortic Banding Model.

The aim of the study was to evaluate a balloon expandable transcatheter heart valve (THV) system (Myval) at 6-month follow-up in ovine banding model. Eleven THV systems were implanted via carotid approach. There were 2 procedure-related deaths and 2 premature deaths.
