Impact of diabetes mellitus on disease severity and patient survival in idiopathic pulmonary arterial hypertension: data from the Polish multicentre registry (BNP-PL).

BACKGROUND: Recent studies revealed that alterations in glucose and lipid metabolism in idiopathic pulmonary arterial hypertension (IPAH) are associated with disease severity and poor survival. However, data regarding the impact of diabetes mellitus (DM) on the prognosis of patients with IPAH remain scarce. The aim of our study was to determine that impact using data from a national multicentre prospective pulmonary hypertension registry. METHODS: We analysed data of adult patients with IPAH from the Database of Pulmonary Hypertension in the Polish population (BNP­PL) between March 1, 2018 and August 31, 2020. Upon admission, clinical, echocardiographic, and haemodynamic data were collected at 21 Polish IPAH reference centres. The all-cause mortality was assessed during a 30-month follow-up period. To adjust for differences in age, body mass index (BMI), and comorbidities between patients with and without DM, a 2-group propensity score matching was performed using a 1:1 pairing algorithm. RESULTS: A total of 532 patients with IPAH were included in the study and 25.6% were diagnosed with DM. Further matched analysis was performed in 136 patients with DM and 136 without DM. DM was associated with older age, higher BMI, more advanced exertional dyspnea, increased levels of N-terminal pro-brain natriuretic peptide, larger right atrial area, increased mean right atrial pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and all-cause mortality compared with no DM. CONCLUSIONS: Patients with IPAH and DM present with more advanced pulmonary vascular disease and worse survival than counterparts without DM independently of age, BMI, and cardiovascular comorbidities.

European Society of Cardiology: cardiovascular disease statistics 2021.

AIMS: This report from the European Society of Cardiology (ESC) Atlas Project updates and expands upon the widely cited 2019 report in presenting cardiovascular disease (CVD) statistics for the 57 ESC member countries. METHODS AND RESULTS: Statistics pertaining to 2019, or the latest available year, are presented. Data sources include the World Health Organization, the Institute for Health Metrics and Evaluation, the World Bank, and novel ESC sponsored data on human and capital infrastructure and cardiovascular healthcare delivery. New material in this report includes sociodemographic and environmental determinants of CVD, rheumatic heart disease, out-of-hospital cardiac arrest, left-sided valvular heart disease, the advocacy potential of these CVD statistics, and progress towards World Health Organization (WHO) 2025 targets for non-communicable diseases. Salient observations in this report: (i) Females born in ESC member countries in 2018 are expected to live 80.8 years and males 74.8 years. Life expectancy is longer in high income (81.6 years) compared with middle-income (74.2 years) countries. (ii) In 2018, high-income countries spent, on average, four times more on healthcare than middle-income countries. (iii) The median PM2.5 concentrations in 2019 were over twice as high in middle-income ESC member countries compared with high-income countries and exceeded the EU air quality standard in 14 countries, all middle-income. (iv) In 2016, more than one in five adults across the ESC member countries were obese with similar prevalence in high and low-income countries. The prevalence of obesity has more than doubled over the past 35 years. (v) The burden of CVD falls hardest on middle-income ESC member countries where estimated incidence rates are ∼30% higher compared with high-income countries. This is reflected in disability-adjusted life years due to CVD which are nearly four times as high in middle-income compared with high-income countries. (vi) The incidence of calcific aortic valve disease has increased seven-fold during the last 30 years, with age-standardized rates four times as high in high-income compared with middle-income countries. (vii) Although the total number of CVD deaths across all countries far exceeds the number of cancer deaths for both sexes, there are 15 ESC member countries in which cancer accounts for more deaths than CVD in males and five-member countries in which cancer accounts for more deaths than CVD in females. (viii) The under-resourced status of middle-income countries is associated with a severe procedural deficit compared with high-income countries in terms of coronary intervention, ablation procedures, device implantation, and cardiac surgical procedures. CONCLUSION: Risk factors and unhealthy behaviours are potentially reversible, and this provides a huge opportunity to address the health inequalities across ESC member countries that are highlighted in this report. It seems clear, however, that efforts to seize this opportunity are falling short and present evidence suggests that most of the WHO NCD targets for 2025 are unlikely to be met across ESC member countries.

Longer Hospitalizations and Higher In-Hospital Mortality for Acute Heart Failure during the COVID-19 Pandemic in Larger vs. Smaller Cardiology Departments: Subanalysis of the COV-HF-SIRIO 6 Multicenter Study.

Background: The coronavirus disease-2019 (COVID-19) pandemic is surging across Poland, leading to many direct deaths and underestimated collateral damage. We aimed to compare the influence of the COVID-19 pandemic on hospital admissions and in-hospital mortality in larger vs. smaller cardiology departments (i.e., with ≥ 2000 vs. < 2000 hospitalizations per year in 2019). Methods: We performed a subanalysis of the COV-HF-SIRIO 6 multicenter retrospective study including all patients hospitalized in 24 cardiology departments in Poland between January 1, 2019 and December 31, 2020, focusing on patients with acute heart failure (AHF) and COVID-19. Results: Total number of hospitalizations was reduced by 29.2% in larger cardiology departments and by 27.3% in smaller cardiology departments in 2020 vs. 2019. While hospitalizations for AHF were reduced by 21.8% and 25.1%, respectively. The length of hospital stay due to AHF in 2020 was 9.6 days in larger cardiology departments and 6.6 days in smaller departments (p < 0.001). In-hospital mortality for AHF during the COVID-19 pandemic was significantly higher in larger vs. smaller cardiology departments (10.7% vs. 3.2%; p < 0.001). In-hospital mortality for concomitant AHF and COVID-19 was extremely high in larger and smaller cardiology departments accounting for 31.3% vs. 31.6%, respectively. Conclusions: During the COVID-19 pandemic longer hospitalizations and higher in-hospital mortality for AHF were observed in larger vs. smaller cardiology departments. Reduced hospital admissions and extremely high in-hospital mortality for concomitant AHF and COVID-19 were noted regardless of department size.

Gene Variants Related to Cardiovascular and Pulmonary Diseases May Correlate with Severe Outcome of COVID-19.

Background: Severe outcomes of COVID-19 account for up to 15% of all cases. The study aims to check if any gene variants related to cardiovascular (CVD) and pulmonary diseases (PD) are correlated with a severe outcome of COVID-19 in a Polish cohort of COVID-19 patients. Methods: In this study, a subset of 747 samples from unrelated individuals collected across Poland in 2020 and 2021 was used and whole-genome sequencing was performed. Results: The GWAS analysis of SNPs and short indels located in genes related to CVD identified one variant significant in COVID-19 severe outcome in the HADHA gene, while for the PD gene panel, we found two significant variants in the DRC1 gene. In this study, both potentially protective and risk variants were identified, of which variants in the HADHA gene deserve the most attention. Conclusions: This is the first study reporting the association between the HADHA and DRC1 genetic variants and COVID-19 severe outcome based on the cohort WGS analysis. Although all the identified variants are localised in introns, they may be correlated and therefore inherited along with other risk variants, potentially causative to severe outcome of COVID-19 but not discovered yet.

The Thousand Polish Genomes-A Database of Polish Variant Allele Frequencies.

Although Slavic populations account for over 4.5% of world inhabitants, no centralised, open-source reference database of genetic variation of any Slavic population exists to date. Such data are crucial for clinical genetics, biomedical research, as well as archeological and historical studies. The Polish population, which is homogenous and sedentary in its nature but influenced by many migrations of the past, is unique and could serve as a genetic reference for the Slavic nations. In this study, we analysed whole genomes of 1222 Poles to identify and genotype a wide spectrum of genomic variation, such as small and structural variants, runs of homozygosity, mitochondrial haplogroups, and de novo variants. Common variant analyses showed that the Polish cohort is highly homogenous and shares ancestry with other European populations. In rare variant analyses, we identified 32 autosomal-recessive genes with significantly different frequencies of pathogenic alleles in the Polish population as compared to the non-Finish Europeans, including C2, TGM5, NUP93, C19orf12, and PROP1. The allele frequencies for small and structural variants, calculated for 1076 unrelated individuals, are released publicly as The Thousand Polish Genomes database, and will contribute to the worldwide genomic resources available to researchers and clinicians.

BALLOON AORTIC VALVULOPLASTY WITH VALVER BALLOON CATHETER IN ADULTS WITH SEVERE AORTIC STENOSIS AS A BRIDGE OR PALLIATIVE TREATMENT.

OBJECTIVE: The aim: We aimed to assess the feasibility and safety of performing balloon aortic valvuloplasty (BAV) with Valver balloon catheter (Balton, Poland) in adults with severe aortic stenosis as a bridge or palliative treatment. PATIENTS AND METHODS: Materials and methods: We identified consecutive patients who underwent BAV procedures between May 2019 and March 2020 using Valver balloon catheters. Demographic data, medical history, and clinical characteristics were retrospectively collected in all study patients together with periprocedural data as well as 12-month follow-up data. RESULTS: Results: We included 18 patients. The mean population age was 78.1±8.9 years, and women were 61.1%. The most common co-morbidities were arterial hypertension (88.9%), dyslipidemia (83.3%), and coronary artery disease (72.2%). The baseline mean aortic valve pressure gradient was 49.94±27.02 mmHg and the mean aortic valve area (AVA) was 0.65±0.20 cm2. In all cases, the procedure was performed from the femoral access via the 8F sheath. Two Valver balloon catheter sizes were used 18x40mm (33.3%) and 20x40mm (66.7%). Three periprocedural complications were observed, and none was associated with the Valver balloon catheter per se. The transthoracic echocardiography after the procedure revealed a decrease in the mean pressure gradient of 11.1±8.85 mmHg, and an increase in AVA of 0.21±0.19 cm2. At 12-month follow-up, the mortality rate was 38.9%. CONCLUSION: Conclusions: BAV is a procedure increasingly performed in catheterization laboratories worldwide. This paper confirmed the relative safety of BAV with Valver balloon catheters in the modern era, showing a low incidence of valve and vascular complications.

An implantable pump Lenus pro® in the treatment of pulmonary arterial hypertension with intravenous treprostinil.

BACKGROUND: Subcutaneous treprostinil is a prostacyclin analogue used to treat pulmonary arterial hypertension (PAH). Due to local pain it can cause a deterioration of heart related quality of life (HRQoL) or even abandonment of treatment. The aim of this paper was to assess the feasibility of treatment with intravenous treprostinil administered by means of the Lenus Pro® implantable pump. METHODS: This was a retrospective, multi-center study involving 12 patients (8 females) with PAH treated with a subcutaneous infusion of treprostinil with intolerable pain at the infusion site. Clinical evaluation, including HRQoL assessment with SF-36 questionnaire was performed, before pump implantation and 2-9 months after. The median time of follow-up time was 14 months (4-29 months). RESULTS: After implantation of the Lenus Pro® pump, no statistically significant changes were observed in the 6-min walking distance and NT-proBNP. After implantation 50% of patients were in II WHO functional class (33% before, p = 0,59). There was a significant improvement in HRQoL within the Physical Component Score (28 ± 7 vs 38 ± 8 pts., p < 0,001) and in specific domains of SF-36 form: physical role (31 ± 7 pts. vs. 41 ± 12 pts., p = 0,03), bodily pain (31 ± 12 vs. 50 ± 14 pts., p = 0,02), and vitality (37 ± 8 pts. vs. 50 ± 14 pts., p = 0,03). During the periprocedural period, one patient developed a recurrent haematoma at the implantation site. During follow-up in one patient, the drug delivering cannula slipped out of the subclavian vein, what required repositioning repeated twice, and in another patient an unexpected increase in the drug administration rate was observed. CONCLUSIONS: In patients with PAH who do not tolerate subcutaneous infusion of treprostinil, the use of the Lenus Pro® implantable pump results in significant subjective improvement of vitality and physical aspect of the HRQoL with acceptable safety profile.

Viral Infection of the Heart: Pathogenesis and Diagnosis.

Viral infections of the heart cause serious clinical problems, either as infectious myocarditis, which usually is a consequence of acute infection or as idiopathic dilated cardiomyopathy, resulting rather from a chronic infection. This minireview presents an up-to-date view on pathomechanisms of viral infection of the heart tissues, the role of immune system in controlling infectious process at its various stages and current possibilities of recognizing viral infection of the heart with use of both cardiological and virological methods. Our goal was to present the variety of known viral agents causing heart infection, level of complexity in mutual virus-cell interactions, and consequent clinical scenarios.

Viral Nucleic Acids in the Serum Are Dependent on Blood Sampling Site in Patients with Clinical Suspicion of Myocarditis.

BACKGROUND: The meaning of viral nucleic acids in the myocardium in many cases is difficult for clinical interpretation, whereas the presence of viral nucleic acids in the serum is a marker of active infection. We determined the diagnostic value of viral nucleic acids in ventricular serum and peripheral serum samples in comparison with endomyocardial biopsy (EMB) specimens in patients with clinically suspected myocarditis. METHODS: The viral nucleic acid evaluation was performed in serum samples and EMB specimens by real-time PCR in 70 patients (age: 47 ± 16 years). The biopsy specimens were examined by histo- and immunohistochemistry to detect inflammatory response. RESULTS: The viral nucleic acids were detected in ventricular and peripheral serum, and EMB samples of 10 (14%), 14 (20%), and 32 (46%) patients, respectively. Notably, viral nucleic acids of the same virus as in the EMB sample were present more often in ventricular than in peripheral serum (60 vs. 7%, p = 0.01). A significant concurrence was observed between the positive and the negative results of viral nucleic acids present in EMB and ventricular serum (p = 0.0001). CONCLUSIONS: The detection of the same viral nucleic acid type in the myocardium and in ventricular serum being significantly more frequent than in the peripheral serum may suggest that the site of the blood collection is important for more precise and reliable confirmation of the active viral replication in the heart.

Arrhythmias and conduction disorders in patients with viral heart disease.

Viral heart disease comprises of two cardiovascular entities being evoked by viral infection: acute viral myocarditis and viral cardiomyopathy. Viral myocarditis may completely resolve leaving no traceable sign or cause ongoing inflammation with subsequent development of hypokinetic dilated/non-dilated cardiomyopathy. The exact epidemiology of viral myocarditis remains unknown due to its sometimes asymptomatic course, but according to the Global Burden of Disease Study 2019, the prevalence of myocarditis in young adults is estimated to range between 6.1 per 100,000 in men and 4.4 per 100,000 in women, with the most common viral etiology. According to the literature viral genome can be found in considerable percentage (up to 67,4%) of endomyocardial biopsy specimens obtained from patients with idiopathic left ventricular dysfunction- suggesting viral etiology of the cardiomyopathy. In this review we would like to enlighten most common types of arrhythmias and conduction disorders as well as their prevalence in patients with viral heart disease. Moreover, our paper depicts probable pathological mechanisms in which viruses induce arrhythmias and cardiac conduction system disease in both, acute viral infection and chronic viral disease. We would also like to highlight unresolved problem of sudden death protection in the course of acute myocarditis.

Identification and therapy for patients with heart failure with preserved ejection fraction: An expert opinion of the Heart Failure Association of the Polish Cardiac Society.

Diagnosis of heart failure with preserved ejection fraction (HFpEF) may be challenging owing to the heterogeneous clinical presentation and comorbidities in this population of patients, along with the limited availability of standard diagnostic tools, including natriuretic peptide tests and functional testing. This expert opinion summarizes the current state of knowledge on the identification and therapy for patients with HFpEF based on recent European and American recommendations. This expert opinion aims to aid clinicians in HFpEF management.

Advances in myocarditis management in the light of the latest research and recent guidelines of the European Society of Cardiology.

Myocarditis remains an unknown disease with varying clinical manifestations, often leading to heart failure. The latest 2021 and 2022 guidelines of the European Society of Cardiology (ESC) are the first official European documents updating knowledge on the diagnosis and treatment of myocarditis since the 2013 ESC expert consensus statement. These guidelines and new studies allow standardization and improvements to the management of myocarditis. In this review, we discuss the most important aspects of myocarditis diagnosis, therapies and follow-up based on current knowledge.

Sarcosine May Induce EGF Production or Inhibit the Decline in EGF Concentrations in Patients with Chronic Schizophrenia (Results of the PULSAR Study).

Sarcosine (N-methylglycine), a glutamatergic modulator, reduces the primary negative symptoms of schizophrenia. These beneficial changes might be mediated by trophic factors such as epidermal growth factor (EGF). We assessed associations between initial serum EGF levels or changes in serum EGF levels and symptom severity during the addition of sarcosine to stable antipsychotic treatment and thereby evaluated the associations between glutamatergic modulation, clinical changes and peripheral EGF concentrations. Fifty-eight subjects with a diagnosis of chronic schizophrenia with dominant negative symptoms, stably treated with antipsychotics, completed a prospective 6-month, randomized, double-blind, placebo-controlled study. Subjects received orally 2 g of sarcosine (n = 28) or placebo (n = 30) daily. Serum EGF levels and symptom severity (using the Positive and Negative Syndrome Scale (PANSS) and the Calgary Depression Scale for Schizophrenia (CDSS)) were assessed at baseline, 6-week and 6-month follow-up. Augmentation antipsychotic treatment with sarcosine had no effect on EGF serum levels at any time points. Only the sarcosine group showed a significant improvement in negative symptoms, general psychopathology subscales and the overall PANSS score. We found a reduction in serum EGF levels in the placebo group, but levels in the sarcosine remained stable during the study. Our data indicate that improvement in negative symptoms due to sarcosine augmentation is not directly mediated by EGF, but effective treatment may induce the production or block the decrease in EGF concentrations, which indicates the neuroprotective effect of treatment and confirms the relationship between neuroprotection and EGF levels.

Lower Preoperative Verbal Memory Performance Is Associated with Delirium after Coronary Artery Bypass Graft Surgery: A Prospective Cohort Study.

OBJECTIVE: Cognitive impairment constitutes one of the major risk factors of delirium after coronary artery bypass graft (CABG) surgery; however, it is unclear whether only patients with global cognitive decline are at increased risk for delirium or if individuals with preserved global cognitive functions but impairments in specific cognitive domains are also more vulnerable to developing delirium. Thus, this study aimed to analyze the neurocognitive status of patients scheduled for CABG surgery with the use of an advanced computerized cognitive battery (CNS Vital Signs) and to investigate possible associations between impaired performance in selective cognitive areas and the risk of postoperative delirium development. METHODS: The study enrolled 127 participants with a median age of 67 years (IQR: 63-71). Postoperative delirium developed in 32 (25%) patients.Before surgery, the patients were screened for global cognitive impairment with the use of the Mini-Mental State Examination Test, and the individuals were asked to perform the CNS Vital Signs battery to investigate 12 specific cognitive domains. The Confusion Assessment Method and the Memorial Delirium Assessment Scale were used to screen for a diagnosis of delirium postoperatively. RESULTS: In multivariate models, a lower score of verbal memory-assessed preoperatively was independently associated with the risk of postoperative delirium development. Other independent predictors of delirium included more advanced age, gender female, depression, postoperative pyrexia, and the presence of extracorporeal circulation. CONCLUSIONS: As decreased verbal memory constitutes an independent risk factor for postoperative delirium, a verbal memory test may be a useful predictor of postoperative delirium development.

Expert opinion of the Heart Failure Association of the Polish Society of Cardiology, the College of Family Physicians in Poland, and the Polish Society of Family Medicine on the peri discharge management of patients with heart failure.

Despite advances in the treatment of heart failure (HF), the rate of hospitalisation for exacerbations of the disease remains high. One of the underlying reasons is that recommended guidelines for the management of HF are still too rarely followed in daily practice. Disease exacerbation requiring inpatient treatment is always afactor that worsens the prognosis, and thus signals disease progression. This is also akey moment when therapy should be modified for HF exacerbation, or initiated in the case of newly diagnosed disease. Inpatient treatment and the peri­discharge period is the time when the aetiology and mechanism of HF decompensation should be established. Therapy should be individualised based on aetiology, HF phenotype, and comorbidities; it should take into account the possibilities of modern treatment. According to the recommendations of the European Society of Cardiology (ESC), patients with HF should receive multidisciplinary management. Cooperation between the various members of the multidisciplinary team taking care of patients with HF improves the efficiency and quality of treatment. This document expands and details the information on the peri­discharge management of HF contained in the 2021 ESC guidelines and the 2022 American Heart Association (AHA)/American College of Cardiology (ACC)/Heart Failure Society of America (HFSA) guidelines.

SARS-CoV-2 infection activating a novel variant of the NOTCH3 gene and subsequently causing development of CADASIL.

Introduction: In the following study we describe the diagnostic process and further case analysis of a 30-year-old woman admitted with typical COVID-19 symptoms, who subsequently developed additional symptoms suggesting cerebral autosomal dominant arteriopathy with sub-cortical infarcts and leukoencephalopathy (CADASIL). Material and methods: Other than the standard diagnostic procedures, whole genome sequencing (WGS) was used, which led to following findings. A new variant of the NOTCH3 gene, which led to CADASIL-like symptoms, was found, and it had been most likely activated by the SARS-CoV-2 infection. This novel variant in NOTCH3 has not been found in existing databases and has never been mentioned in research concerning CADASIL before. Results: Furthermore, after subjecting the patient's close relatives to WGS it was found that no other examined person demonstrated the same genetic mutation. Conclusions: It seems therefore that the new variant of NOTCH3 is of de novo origin in the patient's genome. Additionally, the relatively early onset of CADASIL and the unexpectedly severe COVID-19 infection suggest that the two occurred simultaneously: the infection with SARS-CoV-2 accelerated development of CADASIL symptoms and the unusual variant of the NOTCH3 gene contributed to the more severe course of COVID-19.

Comparison of reorganized versus unaltered cardiology departments during the COVID-19 era: A subanalysis of the COV-HF-SIRIO 6 study.

BACKGROUND: Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, numerous cardiology departments were reorganized to provide care for COVID-19 patients. We aimed to compare the impact of the COVID-19 pandemic on hospital admissions and in-hospital mortality in reorganized vs. unaltered cardiology departments. METHODS: The present research is a subanalysis of a multicenter retrospective COV-HF-SIRIO 6 study that includes all patients (n = 101,433) hospitalized in 24 cardiology departments in Poland between January 1, 2019 and December 31, 2020, with a focus on patients with acute heart failure (AHF). RESULTS: Reduction of all-cause hospitalizations was 50.6% vs. 21.3% for reorganized vs. unaltered cardiology departments in 2020 vs. 2019, respectively (p < 0.0001). Considering AHF alone respective reductions by 46.5% and 15.2% were registered (p < 0.0001). A higher percentage of patients was brought in by ambulance to reorganized vs. unaltered cardiology departments (51.7% vs. 34.6%; p < 0.0001) alongside with a lower rate of self-referrals (45.7% vs. 58.4%; p < 0.0001). The rate of all-cause in-hospital mortality in AHF patients was higher in reorganized than unaltered cardiology departments (10.9% vs. 6.4%; p < 0.0001). After the exclusion of patients with concomitant COVID-19, the mortality rates did not differ significantly (6.9% vs. 6.4%; p = 0.55). CONCLUSIONS: A greater reduction in hospital admissions in 2020 vs. 2019, higher rates of patients brought by ambulance together with lower rates of self-referrals and higher all-cause in-hospital mortality for AHF due to COVID-19 related deaths were observed in cardiology departments reorganized to provide care for COVID-19 patients vs. unaltered ones.

[Association of antithyroid peroxidase antibodies with cardiac function in euthyroid women with type 1 diabetes mellitus - assessment with two-dimensional speckle­tracking echocardiography].

INTRODUCTION: The presence of diabetes is associated with loss of cardioprotection in premenopausal women; however, the mechanisms involved remain unknown. Autoimmune factors are suspected to play a role in cardiovascular complications, especially in type 1 diabetes (T1DM). The aim of this pilot study was to explore whether antithyroid peroxidase antibody (aTPO) as a marker of increased immune activity is related to cardiac dysfunction in young, asymptomatic women with T1DM. MATERIAL AND METHODS: Eighty-eight euthyroid women (59 with T1DM and 29 healthy controls) underwent physical examination, laboratory tests, thyroid ultrasound, and two-dimensional speckle-tracking echocardiography. According to the antiperoxidase antibodies (aTPO) titre, the T1DM women were divided into an aTPO positive (T1DM aTPO+) (n = 34) and an aTPO negative (T1DM aTPO-) (n = 25) group. The relationship between thyroid autoimmunity parameters and echocardiographic parameters was evaluated. RESULTS: Global longitudinal strain (GLS) was slightly reduced in the T1DM aTPO+ group compared to T1DM aTPO- and significantly compared to controls (p = 0.051 and p = 0.015, respectively). Although, the lower values of longitudinal strain of left ventricular were found in the majority of segments in the T1DM aTPO+ group in comparison to T1DM aTPO- and controls, significant differences were only found in the two-chamber view (specifically in the anterior segments) between the T1DM aTPO+ and T1DM aTPO- groups (p = 0.030) and in the four-chamber view (specifically in the anterolateral segments) between the T1DM aTPO+ group and controls (p = 0.021). Echocardiographic parameters of diastolic and systolic function of both ventricles were significantly correlated with parameters of thyroid autoimmunity. A logistic regression analysis showed that Hashimoto's thyroiditis (HT) duration [odds ratio (OR): 0.997, 95% confidence interval (CI): 0.995-0.999, p = 0.008), the dose of levothyroxine (OR: 0.814, 95% CI: 0.689-0.960, p = 0.013), and reduced echogenicity on thyroid ultrasound (OR: 0.309, 95% CI: 0.120-0.793, p = 0.013) had a significant influence on reduced GLS. CONCLUSIONS: Our results suggest that coexistence of aTPO with T1DM was associated with poorer myocardial function, particularly in the anterior and anterolateral segments, which may be related to an autoimmune factor. The impaired function of these segments is probably the first sign of myocardial systolic dysfunction in women with T1DM, which needs to be confirmed in further studies.

A quasi-experimental study examining a nurse-led educational program to improve disease knowledge and self-care for patients with acute decompensated heart failure with reduced ejection fraction.

BACKGROUND: Nurse-led education can improve heart failure (HF) knowledge and self-care behaviors, and consequently lead to better patient outcomes. OBJECTIVES: To assess the effectiveness of "The Weak Heart" educational model in enhancing the level of disease knowledge and self-care behaviors among patients hospitalized with acute decompensated heart failure with reduced ejection fraction (HFrEF). MATERIAL AND METHODS: An evidence-based, standardized educational program was implemented for HF patients in Poland. We compared the initial level of HF knowledge - as rated using a self-developed questionnaire and self-care behaviors, evaluated according to the 9-item European Heart Failure Self-care Behavior Scale (9-EHFScBS) - to the results obtained at the 3-month follow-up period with a sample of patients (n = 231) hospitalized with acute decompensated HF (ADHF). RESULTS: The results showed a significant increase in total score of HF knowledge test depending on the time of measurement (χ2 = 356.526, p < 0.001) and in all individual questions on HF. The significant change of the 9-EHFScBS self-care questionnaire was also found in total score (Z = -7.317, p < 0.001), in all domains: autonomous-based adherence (Z = -5.870, p < 0.001); consulting behavior (Z = -7.238, p < 0.001); provider-based adherence (Z = -4.162; p < 0.001) and in relation to all individual statements except statement 7 ("I eat a low salt diet") and statement 9 ("I exercise regularly"). Within 3 months of hospital discharge, 84% (193 out of 231) of participants visited their primary care physician and 79% (183 out of 231) visited a cardiologist in accordance with their individual treatment plan. CONCLUSIONS: "The Weak Heart" educational model is effective in enhancing the level of HF knowledge and self-care behaviors among patients with decompensation of HFrEF.

An expert opinion of the Heart Failure Association of the Polish Cardiac Society on the 2021 European Society of Cardiology guidelines for the diagnosis and treatment of acute and chronic heart failure: Heart failure guidelines from a national perspective.

The Polish expert opinion of the Heart Failure Association of the Polish Cardiac Society on the 2021 European Society of Cardiology (ESC) guidelines for the diagnosis and treatment of heart failure points to differences in many aspects related to heart failure in Poland compared with other European countries. These differences include population issues, epidemiology, diagnostic and treatment options, or the organization of healthcare. This expert opinion also includes a review of new results of clinical trials completed after the publication of the ESC guidelines.
