1. Objective According to the 2021 European Resuscitation Council (ERC) Guidelines, sudden cardiac arrest is the third leading cause of death in Europe. Accurate and reliable data on the epidemiology of sudden cardiac arrest are essential for better understanding its causes and for analyzing treatment outcomes. Currently, comprehensive statistics on cardiac arrest in Poland are unavailable, resulting in limited knowledge about the scale of this medical issue. This study aims to examine the frequency and clinical characteristics of out-of-hospital cardiac arrests occurring nationwide in 2023. 2. Materials and Methods The analysis will include Emergency Medical Activity Cards from the year 2023. Data for the study will be obtained from the National Center for Monitoring Emergency Medical Services via the Department of Emergency Medical Services of the Polish Ministry of Health and from the Polish Medical Air Rescue. Data will be anonymized by data administrators before being provided to the research team. The analysis of the obtained results will be supplemented with publicly available data from the Central Statistical Office (GUS). The analyzed Emergency Medical Activity Cards will be evaluated according to the Utstein Out-of-Hospital Cardiac Arrest Registry template from 1991, with subsequent updates, the latest being in 2024, published under the title: "Cardiac arrest and cardiopulmonary resuscitation outcome reports: 2024 update of the Utstein Out-of-Hospital Cardiac Arrest Registry template - ILCOR Scientific Statement." 3. Study Population Adults who experienced out-of-hospital cardiac arrest in 2023. 4. Inclusion and Exclusion Criteria Exclusion Criteria: Age under 18 years. Inclusion Criteria: Emergency Medical Activity Cards containing at least one of the following criteria: In section IV DIAGNOSIS with ICD-10 codes: I46, R98, R96.

This project is based on a predictive alghorithm (Multifactorial Dynamic Perfusion Index-MDPI) already published and covered by a patent. The MDPI is based on a dynamic collection of 7 different variables during cardiopulmonary bypass (CPB) and provides a probability index for postoperative acute kidney injury. The study design is a multicenter observational prospective trial developed through 3 work packages, addressing (1) external validation of the MDPI in a series of 800 adult cardiac surgery patients collected in 2 Institutions (2) development of a novel MDPI to be applied in infants \< 20 kg undergoing cardiac surgery (200 patients) and (3) verification of of other possible outcomes that may be predicted by the MDPI. Since many of the predictive variables are modifiable by the perfusionist/anesthesiologist during CPB, it is a tool that allows therapeutic manouvres. Ultimately, the MDPI will be incorporated in a dedicated monitor to provide an on-line "flight control" during CPB. Work package 1 will be performed at Units 1 and 2; the parameters composing the MDPI will be collected using the existing CPB monitors that routinely measure the hematocrit, the oxygen delivery, the time of exposure to a pre-defined critical oxygen delivery, the mean arterial pressure, and the CPB duration. Blood lactates and transfusions will be manually inputed. The MDPI will be calculated off-line and tested for association and predictivity (discrimination and calibration) with respect to postoperative AKI defined according to the K-DIGO classification. Workpackage 2 is dedicated to infants, with the purpose of developing an MDPI dedicated to low-weight infants (I-MDPI). This will be develop in Unit 1 that performs congenital heart surgery. The same variables of the MDPI will be collected, plus additional variables specific for infants (blood to prime the oxygenator, plasma for the same purpose; venous oxygen saturation, and others). The variables being independently associated with AKI will enter a logistic regression equation that will be the basis for the I-MDPI. Workpackage 3 considers that AKI is associated with a prolonged mechanical ventilation time, prolonged stay in the intensive care unit and in the hospital; and mortality. Therefore, the MDPI may be predictive of other postoperative complications, apart from AKI, and even of mortality. Some of the factors included in the MDPI may directly (low hematocrit) or indirectly (prolonged CPB duration, excessive hemodilution, low mean arterial pressure) affect the hemostatic system and/or trigger packed red cells transfusions. Additionally, CPB itself is a determinant of a coagulophatic state with associated postoperative bleeding which, in turns, increases the mortality. The specific aim 3 is to confirm the hypothesis that the MDPI may be predictive of one or more of this non-AKI postoperative complications and of 30-days mortality. In the same series of work package and aim 1, these complications will be collected and the MDPI tested for predictive ability of each one of these complications and 30-days mortality. At present, the MDPI can only be calculated off-line, and this greatly limits its applicability. The last step of the aim 3 is based on the involvement of software experts and partnership with companies interested in including the MDPI into their existing monitors; as such, the MDPI patent would be given under licence of the existing patent owned by the IRCCS Policlinico San Donato.
NCT06707116
The goal of this observational study is to understand the role of health literacy in shaping the relationship between gender differences, illness identity, and self-efficacy in geriatric patients with cardiac diseases. The main question it aims to answer is: Does health literacy mediate the relationship between gender, illness identity, and self-efficacy in elderly cardiac patients? Participants with diagnosed cardiac conditions, will complete online surveys assessing their health literacy, illness identity, and self-efficacy over a one-year period. Structural Equation Modeling (SEM) will be used to analyze the relationships among these variables.
NCT02802254
The aim of this study is to evaluate the efficiency of a minimal intervention on risk perception of physical inactivity in patients with known coronary heart disease (CHD) and patients at risk for CHD. Therefore half of the patients (intervention group) get a personal feedback on their individual level of physical activity measured by pedometers and self-report questionnaires plus information about the risk factor 'physical inactivity' for heart diseases. Following the hypotheses the feedback should increase the patients risk perception of physical inactivity and furthermore increase physical activity.

This study will be a retrospective study. The patient data from the electronic medical records and existing database will be collected and analyzed. Primary endpoints will be postoperative mortality (within 30 days) and overall complications and length of hospital stay. The secondary endpoints will be myocardial infarction, cardiac death, CHF, arrhythmia, ischemia, stroke, neurological complications, length of ICU stay, re-admission rate, infections, pulmonary complications, length of intubation time, length of ventilation time, and acute renal failure.
NCT00296738
Myocardial scintigraphy with 123I-MIBG allows for visual and semi-quantitative assessment of sympathetic cardiac innervation using the hear to mediastinum ratio (HMR). Impaired cardiac MIBG clearance may occur in patients with congestive heart failure (CHF). The purpose of present study was to develop and validate a quantitative index for the assessment of cardiac MIBG uptake kinetics using SPECT/CT for diagnosis of CHF

A new, innovative software image processing method, wide beam reconstruction (WBR), utilizes resolution recovery and incorporates Poisson noise-reduction into the reconstruction process of NM images. This method facilitates the reconstruction of low count density myocardial perfusion SPECT images. Preliminary research indicates that SPECT acquisition time consequently can be reduced by 60% (less than 5 minutes) for rest and by 75% (just over 3 minutes) for stress, while tomographic image quality is maintained, or even improved. Such a decrease in image acquisition time decreases patient discomfort during the tomographic acquisition, decreases the opportunity for patient motion, and improves laboratory efficiency.
