The impact of the coronavirus pandemic on patients hospitalized due to acute coronary syndrome.

The coronavirus disease 2019 (COVID-19) pandemic significantly increased mortality worldwide. However, only part of the excess mortality is related directly to the infection. Local healthcare accessibility, time to reach medical care and patients' reluctance to seek medical aid strongly affected the treatment results in many fields.

Del Nido versus cold blood cardioplegia in adult patients with impaired ejection fraction undergoing valvular and complex heart surgery.

Background: There is sparse evidence on the efficacy of del Nido cardioplegia in high-risk patients with reduced ejection fraction undergoing valvular or complex heart surgery, and further investigation is required.

Methods: An institutional registry was searched for patients who underwent valvular or complex heart surgery and had an ejection fraction <40%. Subjects who received del Nido cardioplegia (DNC) and cold blood cardioplegia (CBC) were selected.

Use of del Nido cardioplegia in acute coronary syndrome cases with decreased ejection fraction.

Background: There has been increasing interest in using del Nido cardioplegia in adult cardiac surgery. However, there is limited evidence for its efficacy in patients with acute coronary syndrome and reduced ejection fraction.

Methods: This study examined patients with decreased ejection fraction (EF < 40%) who were hospitalized due to acute coronary syndrome and received either del Nido (DN) or cold blood cardioplegia (CB).

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.

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.
