Effects of Exergaming in Patients with Cardiovascular Disease Compared to Conventional Cardiac Rehabilitation: A Systematic Review and Meta-Analysis.
2022
Background: Exercise-based cardiac rehabilitation (CR) programs are used for improving prognosis and quality of life in patients with cardiovascular disease (CVD). Nonetheless, adherence to these programs is low, and exercise-based CR programs based on virtual reality (i.e., exergaming) have been proposed as an alternative to conventional CR programs. However, whether exergaming programs are superior to conventional CR programs in patients with CVD is not known. Objective: This systematic review with meta-analysis was conducted to explore whether exergaming enhances exercise capacity, quality of life, mental health, motivation, and exercise adherence to a greater extent than conventional CR…
Factors affecting short- and long-term survival of patients with acute coronary syndrome treated invasively using intravascular ultrasound and fracti…
2023
Background: Intravascular ultrasound (IVUS) and fractional flow reserve (FFR) are invasive procedures increasingly used in acute coronary syndrome (ACS). Aims: The aim of this study was to evaluate the prevalence of IVUS and FFR use in patients with ACS in Poland and to assess the safety of these procedures, as well as their impact on short- and long-term survival. Methods and results: The retrospective study included 103849 patients enrolled in the PL-ACS registry in 2017-2020. IVUS was performed in 1,727 patients, FFR in 1,537 patients, both procedures in 37 patients. The frequency of performing FFR in ACS over the years increased from 1.3% to 1.8% (p <0.0001) and IVUS from 1.7% to 2.3% (…
Gender-related differences in men and women with ST-segment elevation myocardial infarction and incomplete infarct-related artery flow restoration: a…
2018
Introduction: Little is known about gender-related differences in ST-segment elevation myocardial infarction (STEMI) and incomplete infarct-related artery (IRA) reperfusion after primary percutaneous coronary intervention (pPCI). Aim: To evaluate gender-related differences in clinical characteristics and prognosis in patients with STEMI and incomplete IRA reperfusion after pPCI. Material and methods: From 42,752 STEMI patients hospitalized between 2009 and 2011 in Poland we analyzed a group of 984 (36%) females and 1,746 (64%) males with less than Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow following pPCI. Results: Women were older than men (72.0 ±11.3 vs. 64.0 ±11.7 years; p …

Transitioning from Preclinical to Clinical Heart Failure with Preserved Ejection Fraction: A Mechanistic Approach.
2020
International audience; To better understand heart failure with preserved ejection fraction (HFpEF), we need to better characterize the transition from asymptomatic pre-HFpEF to symptomatic HFpEF. The current emphasis on left ventricular diastolic dysfunction must be redirected to microvascular inflammation and endothelial dysfunction that leads to cardiomyocyte remodeling and enhanced interstitial collagen deposition. A pre-HFpEF patient lacks signs or symptoms of heart failure (HF), has preserved left ventricular ejection fraction (LVEF) with incipient structural changes similar to HFpEF, and possesses elevated biomarkers of cardiac dysfunction. The transition from pre-HFpEF to symptomati…
Right Ventricular Dysfunction Staging System for Mortality Risk Stratification in Heart Failure with Preserved Ejection Fraction
2020
Right ventricular dysfunction (RVD) parameters are increasingly important features in heart failure with preserved ejection fraction (HFpEF). We sought to evaluate the prognostic impact of a progressive RVD staging system by combining the tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (TAPSE/PASP) ratio with functional tricuspid regurgitation (TR) severity. We prospectively included 1355 consecutive HFpEF patients discharged for acute heart failure (HF). Of them, in 471 (34.7%) patients, PASP could not be accurately measured, leaving the final sample size to be 884 patients. Patients were categorized as Stage 1: TAPSE/PASP &ge
Enhanced Permeability and Retention-like Extravasation of Nanoparticles from the Vasculature into Tuberculosis Granulomas in Zebrafish and Mouse Mode…
2018
The enhanced permeability and retention (EPR) effect is the only described mechanism enabling nanoparticles (NPs) flowing in blood to reach tumors by a passive targeting mechanism. Here, using the transparent zebrafish model infected with Mycobacterium marinum we show that an EPR-like process also occurs allowing different types of NPs to extravasate from the vasculature to reach granulomas that assemble during tuberculosis (TB) infection. PEGylated liposomes and other NP types cross endothelial barriers near infection sites within minutes after injection and accumulate close to granulomas. Although similar to 100 and 190 nm NPs concentrated most in granulomas, even similar to 700 nm liposo…
Operācijas rezultātu korelācija ar miega artērijas revaskularizācijas metodēm

Anotācija Miega artēriju stenozes ķirurģiskai korekcijai karotīdu endarterectomijai ir būtiska nozīme insulta profilaksē. Promocijas darba mērķis: Izvērtēt miega artērijas endarterektomiju operāciju rezultātus, ņemot vērā intima-media slāņa biezumu un pacienta dzīves kvalitāti. Promocijas darbā autore veikusi pētījumu, kas atspoguļo karotīdu endarterektomijas operāciju rezultātus (komplikācijas, dzīves kvalitātes izmaiņas) un intīmas hiperplāzijas attīstību postoperatīvā periodā. Izveidota speciāla dzīves kvalitātes novērtēšanas anketa pacientiem ar miega artērijas sašaurinājumu. Pētījuma materiālu veido 104 pacienti, kuriem veiktas karotīdu endarterektomijas.

Pressor amines in coronary artery bypass grafting procedure with and without the use of extracorporeal circulation
2017
Wstęp: Operacje rewaskularyzacji mięśnia sercowego są najczęściej wykonywanymi procedurami w praktyce kardiochirurgicznej. Rozwój technik pomostowania tętnic wieńcowych bez użycia krążenia pozaustrojowego spowodował, iż modyfikacjom uległy również techniki znieczulenia. W prowadzeniu znieczulenia do zabiegów typu OPCA B anestezjolog musi szczególnie szybko reagować na częste, czasem nieprzewidywalne zmiany sytuacji hemodynamicznej. Cel pracy: Celem pracy było porównanie zastosowania amin presyjnych wśród pacjentów poddanych chirurgicznej rewaskularyzacji mięśnia sercowego z krążeniem pozaustrojowym i bez niego. Materiał i metody: Badanie miało charakter retrospektywny. Badaniem objęto 80 ch…
Underweight and obesity are related to higher mortality in patients undergoing coronary angiography: The KARDIO invasive cardiology register study
2022
Background: In patients with some cardiovascular disease conditions, slightly elevated body mass index (BMI) is associated with a lower mortality risk (termed “obesity paradox”). It is uncertain, however, if this obesity paradox exists in patients who have had invasive cardiology procedures. We evaluated the association between BMI and mortality in patients who underwent coronary angiography. Methods: We utilised the KARDIO registry, which comprised data on demographics, prevalent diseases, risk factors, coronary angiographies, and interventions on 42,636 patients. BMI was categorised based on WHO cut-offs or transformed using P-splines. Hazard ratios (HRs) with 95% confidence intervals (CI…
