Predicting 3-year mortality after myocardial infarction in a structured care program: A comparative analysis of Cox regression and machine learning models

Cyntia Szymańska-Łyczkowska, R Dankowski, Julita Fedorowicz, Joanna Loda et autres

BACKGROUND: Accurate risk stratification after myocardial infarction (MI) remains essential for optimizing long-term management. The advantage of machine learning (ML) over conventional statistical models in real-world clinical settings remains uncertain. AIMS: Our aim was to compare the performance of Cox proportional hazards …

Loop Diuretic Dose and Nutritional Status of Patients with Heart Failure with Reduced Ejection Fraction

Filip Sawczak, Aleksandra Soloch, Maria Cierzniak, Alicja Szubarga et autres

Background/Objectives: Loop diuretics are among the most commonly used drugs in patients with heart failure with reduced ejection fraction (HFrEF). Higher doses of these diuretics are associated with poorer clinical status and may contribute to malnutrition. The study aims to assess the …

Intravascular Ultrasound for the Prevention of Coronary Artery Occlusion During Transcatheter Aortic Valve Replacement

Helena Krysztofiak, Krzysztof Krawczyk, Witold Gwóźdź, Jerzy Sacha

Predicting coronary artery occlusion after transcatheter aortic valve replacement (TAVR) is usually based on computed tomography angiography (CTA). The primary risk factors seem to be a low coronary artery take-off and a small aortic root. However, CTA sometimes provides ambiguous risk assessment, …

Correlations between soluble ST2 concentration and the nutritional status in patients with heart failure with reduced ejection fraction — cross-sectional study

Marta Kałużna‐Oleksy, Filip Waśniewski, Magdalena Szczechla, Filip Sawczak et autres

BACKGROUND: Heart failure (HF) is a global problem that stimulates research on markers associated with the diagnosis and course of the disease. Soluble suppression of tumorigenicity-2 (sST2) is a receptor for interleukin-33 and is associated with increased mortality rates in HF patients. …

SARS-CoV-2 vaccine hesitancy in patients with heart failure: relationship with patient characteristics and pre-pandemic quality of life – a cohort study

Filip Sawczak, Agata Kukfisz, Maria Cierzniak, Alicja Szubarga et autres

Heart failure (HF) patients are vulnerable to a complicated course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This research analysed the relationship between the decision not to be immunised against SARS-CoV-2, clinical and epidemiological factors, and the pre-pandemic health-related quality …
