Thrombin generation, fibrin clot permeation and lysis in patients with severe mitral regurgitation undergoing transcatheter edge-to-edge mitral valve repair: Mitral Fibrin Study.

INTRODUCTION: The intricate management of heart failure (HF), especially in the context of reduced ejection fraction, is compounded by an elevated risk of thromboembolic events. Existing studies offer inconclusive insights into the interplay between MR and the coagulation system. OBJECTIVES: This study aimed to investigate the impact of transcatheter edge-to-edge repair (TEER) on specific coagulation parameters in HF patients. PATIENTS AND METHODS: A cohort of 31 HF patients with severe MR undergoing TEER underwent systematic evaluation at three time points (V1, V2, and V3). Coagulation parameters, including fibrinogen concentration, thrombin generation, fibrin clot permeability (Ks), and clot lysis time (CLT), were assessed (n = 27 [V2], and n = 25 [V3]). RESULTS: TEER induced changes in fibrinogen levels (P = 0.01, V3 vs. V2) and improved fibrin clot properties over a 50-day follow-up (Ks, P = 0.01, V3 vs. V2). No significant differences were observed among time points in analyzed blood clot parameters. Correlation analysis showed that baseline CLT was significantly associated with delta NT-proBNP, (P = 0.049; r = 0.40). Multivariable analysis demonstrated that baseline CLT was an independent predictor of the early post-TEER NT-proBNP change (R2 = 0.55, P = 0.02). CONCLUSIONS: We found that fibrinogen levels decreased, and permeation coefficient increased over a median 50-day post-TEER follow-up, compared to early post-procedure assessments. Other blood coagulation parameters remained unchanged from baseline to both follow-up periods after TEER. Finally, CLT was an independent predictor of early NT-proBNP increase, emphasizing its role as an indicator of the hemodynamic response to TEER.

Heart failure care in the Central and Eastern Europe and Baltic region: status, barriers, and routes to improvement.

Despite improvements over recent years, morbidity and mortality associated with heart failure (HF) are higher in countries in the Central and Eastern Europe and Baltic region than in Western Europe. With the goal of improving the standard of HF care and patient outcomes in the Central and Eastern Europe and Baltic region, this review aimed to identify the main barriers to optimal HF care and potential areas for improvement. This information was used to suggest methods to improve HF management and decrease the burden of HF in the region that can be implemented at the national and regional levels. We performed a literature search to collect information about HF epidemiology in 11 countries in the region (Bulgaria, Croatia, Czechia, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Serbia, and Slovenia). The prevalence of HF in the region was 1.6-4.7%, and incidence was 3.1-6.0 per 1000 person-years. Owing to the scarcity of published data on HF management in these countries, we also collected insights on local HF care and management practices via two surveys of 11 HF experts representing the 11 countries. Based on the combined results of the literature review and surveys, we created national HF care and management profiles for each country and developed a common patient pathway for HF for the region. We identified five main barriers to optimal HF care: (i) lack of epidemiological data, (ii) low awareness of HF, (iii) lack of national HF strategies, (iv) infrastructure and system gaps, and (v) poor access to novel HF treatments. To overcome these barriers, we propose the following routes to improvement: (i) establish regional and national prospective HF registries for the systematic collection of epidemiological data; (ii) establish education campaigns for the public, patients, caregivers, and healthcare professionals; (iii) establish formal HF strategies to set clear and measurable policy goals and support budget planning; (iv) improve access to quality-of-care centres, multidisciplinary care teams, diagnostic tests, and telemedicine/telemonitoring; and (v) establish national treatment monitoring programmes to develop policies that ensure that adequate proportions of healthcare budgets are reserved for novel therapies. These routes to improvement represent a first step towards improving outcomes in patients with HF in the Central and Eastern Europe and Baltic region by decreasing disparities in HF care within the region and between the region and Western Europe.

Clinical characteristics and long-term outcomes of patients with heart failure with improved ejection fraction. First Polish experience from LECRA-HF registry.

PURPOSE: Heart failure (HF) with improved ejection fraction (HFimpEF) is a new category of HF introduced in the newest European Society of Cardiology guidelines. However, clinical characteristics and long-term outcomes of HFimpEF patients remain insufficiently elucidated. We sought to characterize Polish HFimpEF patients and determine their long-term mortality. MATERIAL AND METHODS: Of 1186 patients enrolled in the single-center Lesser Poland Cracovian Heart Failure (LECRA-HF) registry between 2009 and 2019 and hospitalized due to HF decompensation, 340 (28.7%) were those with HF with reduced ejection fraction (HFrEF). Based on follow-up echocardiography, 61 (17.9%) of them were classified as HFimpEF and the remaining as HFnon-impEF. RESULTS: HFimpEF patients were more frequently females (P â€‹< â€‹0.001), had higher baseline left ventricular ejection fraction (LVEF, P â€‹< â€‹0.001), had less often a history of diabetes (P â€‹= â€‹0.024), severe chronic kidney disease (P â€‹= â€‹0.026) or prior myocardial infarction (P â€‹= â€‹0.008) than HFnon-impEF patients. By multivariable analysis the HFimpEF diagnosis was independently predicted by baseline NYHA I/II (odds ratio [OR] 2.347, 95% confidence interval [95%CI] 1.020-5.405), non-ischemic etiology (OR 3.096, 95%CI 1.587-6.024), lack of diabetes mellitus (OR 2.016, 95%CI 1.059-3.846) and higher baseline LVEF (OR 1.084, 95%CI 1.042-1.126, per 1%). Within the median 49 (25-77) months all-cause mortality was lower in HFimpEF than in HFnon-impEF (10.8 vs 16.4%/year, P â€‹= â€‹0.004). CONCLUSIONS: Our findings indicate that every sixth Polish patient with HFrEF has a chance to improve LVEF during follow-up and to become a HFimpEF patient. Baseline characteristics of HFimpEF patients are different from HFnon-impEF. Simultaneously, the HFimpEF diagnosis is associated with higher long-term survival.

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.

Coronary Slow-Flow Phenomenon in Takotsubo Syndrome: The Prevalence, Clinical Determinants, and Long-Term Prognostic Impact.

Patients with takotsubo syndrome (TTS) may present coronary slow flow (CSF) in angiography performed in the acute myocardial infarction (MI). However, the detailed clinical relevance and its long-term impact remain poorly understood. Among 7771 MI patients hospitalized between 2012 and 2019, TTS was identified in 82 (1.1%) subjects. The epicardial blood flow was assessed with thrombolysis in myocardial infarction (TIMI) scale and corrected TIMI frame count (TFC), whereas myocardial perfusion with TIMI myocardial perfusion grade (TMPG). CSF was defined as TIMI-2 or corrected TFC > 27 frames in at least one epicardial vessel. CSF was identified in 33 (40.2%) TTS patients. In the CSF-TTS versus normal-flow-TTS group, lower values of left ventricular ejection fraction on admission (33.5 (25-40) vs. 40 (35-45)%, p = 0.019), more frequent midventricular TTS (27.3 vs. 8.2%, p = 0.020) and the coexistence of both physical and emotional triggers (9.1 vs. 0%, p = 0.032) were noted. Within a median observation of 55 months, higher all-cause mortality was found in CSF-TTS compared with normal-flow TTS (30.3 vs. 10.2%, p = 0.024). CSF was identified as an independent predictor of long-term mortality (hazard ratio 10.09, 95% confidence interval 2.12-48.00, p = 0.004). CSF identified in two-fifths of TTS patients was associated with unfavorable long-term outcomes.

The Prognostic Significance of Atrial Fibrillation and Left Atrium Size in Patients with Aortic Stenosis.

Aim    Aortic stenosis increases left atrial (LA) pressure and may lead to its remodeling. This can cause supraventricular arrhythmia. The aim of this study was to determine if the size of the LA and the presence of atrial fibrillation are related to the prognosis of patients with aortic stenosis.Material and methods    Clinical evaluation and standard transthoracic echocardiographic studies were performed in 397 patients with moderate to severe aortic stenosis.Results    In all patients, LA dimension above the median (≥43 mm) was associated with a significantly higher risk of death [HR 1.79 (CL 1.06-3.03)] and a LA volume above the median of 80 ml was associated with a significantly higher risk of death [HR 2.44 (CI 1.12-5.33)]. The presence of atrial fibrillation was significantly associated with a higher risk of death (p <0.0001). The presence of atrial fibrillation [HR 1.69 (CI 1.02-2.86)], lower left ventricular ejection fraction [HR 1.23 (CI 1.04-1.45)], higher NYHA heart failure class [HR 4.15 (CI 1.40-13.20)] and renal failure [HR 2.10 (CI 1.31-3.56)] were independent risk factors of death in patients in aortic stenosis.Conclusion    The size and volume of the LA and the occurrence of atrial fibrillation are important risk factors for death in patients with aortic stenosis. The presence of renal dysfunction, low left ventricular ejection fraction, high NYHA functional class and atrial fibrillation are independent risk factors of poor prognosis in patients with aortic stenosis.

Spot Urinary Creatinine Concentration in Patients with Chronic Heart Failure Identifies a Distinct Muscle-Wasting Phenotype with a Strikingly Different Risk of Mortality.

BACKGROUND: There is a raising awareness that heart failure (HF) is a highly heterogeneous, multiorgan syndrome with an increasing global prevalence and still poor prognosis. The comorbidities of HF are one of the key reasons for presence of various phenotypes with different clinical profile and outcome. Heterogeneity of skeletal muscles (SMs) quantity and function may have an impact on patient's phenotype. AIM: We intended to compare clinical characteristics of phenotypes defined by a combination of various SM mass taken as a fat-free compartment from DEXA scans and different levels of SUCR (Spot Urinary Creatinine). All-cause mortality with mortality predicted by MAGGIC in such phenotypes were compared. METHODS: In 720 HF patients with reduced ejection fraction (age: 52.3 ± 10 years, female: 14%, NYHA: 2.7 ± 0.7, LVEF: 24.3 ± 7.3%), admitted to the hospital for heart transplantation candidacy assessment, morning SUCR along with body composition scanning (DEXA) was performed. All study participants were dichotomized twice, first by low or normal appendicular muscle mass index (ASMI) and second by SUCR (Spot Urinary Creatinine) < and ≥of 1.34 g/L. Four study groups (phenotypes) were created as combinations of lower or higher SUCR and low or normal ASMI. RESULTS: Low ASMI was found in 242 (33.6%) patients, while the remaining 478 had normal muscle mass. In 446 patients (61.9%), SUCR was <1.34 g/L. During 3 years of follow-up, 223 (31.0%) patients died (all-cause). The phenotype of lower both ASMI and SUCR was associated with the highest mortality. The death rate in phenotype with both low ASMI and SUCR exceeded by 70% the risk estimated by MAGGIC. This difference was significant as judged by the 95% confidence interval for MAGGIC estimation. In Cox regression analysis adjusted for MAGGIC and parameters known to increase risk, the relative risk of patients with phenotype of low both ASMI and SUCR was elevated by 45-55% as compared to patients with all other phenotypes. The protective role of higher SUCR in patients with muscle wasting was, therefore, confirmed in Cox analysis. CONCLUSIONS: Measurement of SUCR in HF patients can identify clinical phenotypes with skeletal muscle wasting but strikingly different risk of death that is actually not captured by MAGGIC score. The higher level of SUCR was associated with similar risk independently of presence of muscle wasting. As the analysis of SUCR is cheap and easy to perform, it should be further tested as a potentially useful biomarker, which may precisely phenotype HF patients independently of their skeletal muscle status.

Gender-related and PUFA-related differences in lipoprotein-associated phospholipase A2 levels in patients with type 2 diabetes and atherosclerotic cardiovascular disease.

BACKGROUND: Lipoprotein-associated phospholipase A2 (Lp-PLA2) may play an important role in the development of atherosclerotic cardiovascular disease (ASCVD). Increased plasma levels of Lp-PLA2 may predict future cardiovascular (CV) events in type 2 diabetes (T2D). The potential beneficial effects of polyunsaturated fatty acids (PUFA) on ASCVD have been widely investigated. However, the impact of different PUFA concentrations on Lp-PLA2 remains uncertain. OBJECTIVES: We sought to determine the intergender differences in a population of patients with both T2D and ASCVD regarding Lp-PLA2 mass and the association between Lp-PLA2 mass and plasma levels of PUFA. MATERIAL AND METHODS: In this cross-sectional study, we measured the Lp-PLA2 mass, PUFA concentrations and inflammatory markers in 74 patients (49 males and 25 females) with T2D and ASCVD. RESULTS: In this very high-risk population, males had, on average, 33.6% higher levels of Lp-PLA2 than females. The Lp-PLA2 mass was positively associated with interleukin 6 (IL-6) (r = 0.27, p = 0.019), creatinine (r = 0.29, p = 0.03) and triglyceride levels (r = 0.41, p = 0.002). Additionally, male gender and higher levels of triglycerides, leptin, oxidized low-density lipoprotein (oxLDL), and intercellular adhesion molecule 1 (ICAM-1) were independent predictors for an increased Lp-PLA2. Moreover, arachidonic acid (AA) negatively correlated with Lp-PLA2 (r = -0.26, p = 0.024), which was especially apparent in the female subgroup. CONCLUSIONS: In the population of patients with ASCVD and T2D, males present with higher plasma levels of Lp-PLA2 than females. Additionally, higher plasma levels of AA were associated with lower Lp-PLA2 levels. Our findings support the utilization of Lp-PLA2 as a novel biomarker in ASCVD risk assessment in a very high CV risk population.

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.

Hemodynamic parameters of aortic valve prostheses - KRAK-AS registry analysis.

Introduction: The treatment of choice for aortic stenosis is a valve replacement. Some patients have post-procedural increased pressure gradient on the implanted prosthesis because of patient-prosthesis mismatch (PPM), known to adversely influence prognosis. The PPM risk should be initially predicted and effort made to avoid this complication, specifically in large body size patients. Aim: To assess the frequency of PPM taking into account the valvular prosthesis type in a real-life population of consecutive patients included in the Krakow aortic stenosis registry. Material and methods: The KRAK-AS registry was conducted in July-October 2016. Patients were assessed before and after valve surgery and during the 3-year follow-up. Patients who underwent aortic valve intervention were clinically and echocardiographically evaluated within a month after surgery and divided into groups depending on the implanted prosthesis type. Analysis of patients with a smaller (< 23 mm) and larger than median (≥ 23 mm) valve diameter was performed. Results: The valve implantation was performed in 229 patients (42 mechanical, 139 biological, 48 transcatheter). No differences between patient groups compared by PPM occurrence was seen at baseline. Median age was 70 years; 55.5% were men. At least moderate PPM (iEOA ≤ 0.85 cm2/m2) was observed in 40% of mechanical valves, 33% of biological valves, and was significantly less frequent (10%) in patients after transcatheter valve implantation, p = 0.0001. Severe PPM (iEOA < 0.65 cm2/m2) was found in 17.6% of mechanical valve PPM patients, 4.3% of biological ones, and no patients after transcatheter procedure. Conclusions: PPM is a frequent phenomenon in the real-life population of patients undergoing surgical aortic valve replacement, being significantly less frequent in the case of a transcatheter procedure.

THE DIETARY HABITS AND NUTRITION BELIEFS OF PATIENTS WITH AORTIC STENOSIS.

OBJECTIVE: Aim: The analysis of dietary knowledge and habits of patients with aortic stenosis, both prior to and post valve implantation. PATIENTS AND METHODS: Materials and methods: Patient with diagnosed moderate or severe aortic stenosis were included into the study. Telephonic dietary interview was performed. It was based on the standard KomPAN questionnaire developed and validated by the Behavioural Nutrition Team, Committee of Human Nutrition of Polish Academy of Sciences. RESULTS: Results: The analysis was conducted in 94 consecutive patients. The pro-health diet index was 4.87 points (3.7; 5.96), while the optimal level was defined as 20 points. The 12.8% of the respondents had low knowledge about nutrition, 79.8% - moderate and 7.4% - good. From 94 patients, 37 had the patientprosthesis mismatch and overweight. The 35.1% of patients with the patient-prosthesis mismatch and overweight considered their nutritional habits as bad, 62.2% as moderate and 2.7% as good. In a group of patients without the patient-prosthesis mismatch the self-opinion about diet was bad in 20.8%, moderate in 72.9% and good in 6.3%. CONCLUSION: Conclusions: Dietary habits and nutritional knowledge in patients with aortic stenosis are inadequate. However, awareness of bad dietary habits in patients who are overweight and have patient-prosthesis mismatch is better compared to the remaining group of patients. The proper dietary education is needed in all patients with aortic stenosis.

Predictive value of metabolic score for insulin resistance and triglyceride glucose-BMI among patients with acute myocardial infarction in 1-year follow-up.

BACKGROUND: Recently two indicators - metabolic score for insulin resistance (METS-IR) and triglyceride glucose-BMI (TyG-BMI) have been proposed as surrogate markers of IR and potential cardiovascular risk factors. The aim of the study was to assess the predictive value of METS-IR and TyG-BMI concerning the incidence of major adverse cardiovascular events (MACE) and all-cause mortality in 1-year follow-up among patients admitted with acute myocardial infarction (AMI). METHODS: Two thousand one hundred fifty-three patients with a median age of 68 years were enrolled in the study. Patients were divided into two groups according to the type of AMI. RESULTS: MACE occurred in 7.9% of the patients in the ST-segment elevation myocardial infarction (STEMI) group and in 10.9% of the non-STEMI (NSTEMI) group. No significant difference in median MACE-IR and TyG-BMI between patients with and without incidence of MACE was found in both groups. None of the examined indices were predictors of MACE in the STEMI and NSTEMI groups. Moreover, both of them did not predict MACE in subgroups of patients classified according to the presence of diabetes. Finally, METS-IR and TyG-BMI were significant predictors of 1-year morality, however with low prognostic value and only in univariate regression analysis. CONCLUSION: METS-IR and TyG-BMI should not be used in predicting MACE among patients with AMI.
