Concentric remodeling and the metabolic-associated steatotic liver disease in patients with type 1 diabetes: an exploratory study.

INTRODUCTION: Diabetic cardiomyopathy in young patients with type 1 diabetes (T1D) usually presents as asymptomatic diastolic heart dysfunction with left ventricle (LV) remodeling. Its prevalence seems to be underestimated. One of the factors seemingly influencing LV remodeling is a metabolic-associated steatotic liver disease (MASLD), which was extensively investigated in patients with type 2 diabetes but not with T1D. This study aimed to describe the correlation between MASLD risk and relative wall thickness (RWT) in young patients with T1D without heart failure symptoms or treatment. MATERIALS AND METHODS: Study participants were recruited at the inpatient diabetology department, in admission order. Patients underwent a set of laboratory tests and echocardiographic examinations. The risk of MASLD was estimated using fatty liver index (FLI). Acquired data was then statistically analyzed. RESULTS: The study group consisted of 55 patients. 25 participants had RWT > 0.42, suggesting LV remodeling. Study participants did not differ in HbA1c, NT-proBNP, HDL, LDL, non-HDL, and uric acid concentrations. However, patients with RWT > 0.42 had higher FLI (40.97 vs. 13.82, p < 0.01) and BMI (27.3 vs. 22.5, p < 0.01) and differed in transaminase concentrations. Moreover, patients with RWT > 0.42 had significantly higher LV mass index (85.6 vs. 68.2 g/m2) and altered mitral ring velocities. In univariable logistic regression, FLI correlated with LV remodeling risk (OR 1.028, p = 0.05). The optimal cutoff point for FLI predicting the RWT > 0.42 was 26.38 (OR 10.6, p = 0.04, sensitivity 0.857, specificity 0.657). CONCLUSIONS: FLI correlates with RWT in patients with T1D independently of diabetes metabolic control and hypothetically may support recognizing T1D patients with a higher risk of LV remodeling.

Insulin resistance may accelerate typical changes in heart function among type 1 diabetes patients, particularly in overweight patients: a preliminary study.

Introduction: Type 1 diabetes (T1D) is a metabolic disease characterized by insulin deficiency and subsequent hyperglycemia. Cardiovascular diseases are the prime cause of mortality and morbidity among patients with T1D. Accumulating metabolic disturbances and accelerated cardiac fibrosis fuel the development of heart dysfunction. As insulin resistance (IR) is a risk factor for the development and worsened course of heart failure, this study aimed to assess its impact on heart function in patients with T1D. Methods: Adult participants were recruited prospectively. The inclusion criteria included a diagnosis of T1D. The exclusion criteria were other types of diabetes, symptoms/treatment of heart failure, AST and/or ALT exceeding the upper reference limit by ≥2x, hepatitis, alcoholism, metformin treatment, and pregnancy. The participants underwent a medical interview, physical examination, biochemical test, and echocardiography. Results: The mean age in the study group was 38 ± 9.6 years, and the mean diabetes duration was 21.8 ± 11.3 years. The median BMI in the study cohort was 23.39 kg/m2. Patients with IR had significantly lower mitral E/A ratio and left ventricular and left atrial volume ratio (LVLAVR), higher LV mass index, and presented with altered mitral annular velocities. Conclusions: IR seems to accelerate the pattern of typical changes in heart function among patients with T1D, especially in the overweight subgroup.

Geographical variation in patient characteristics and outcomes in heart failure with mildly reduced and preserved ejection fraction.

AIMS: Compared to heart failure (HF) with reduced ejection fraction, HF with preserved ejection fraction (HFpEF), and HF with mildly reduced ejection fraction (HFmrEF) are increasing in prevalence, yet little is known about the geographic variation in patient characteristics, treatments and outcomes among these two HF phenotypes. The aim of this study was to investigate geographic differences in HFpEF and HFmrEF. METHODS AND RESULTS: We conducted an individual patient analysis of five clinical trials enrolling patients with HFpEF or HFmrEF from North America (NA), Latin America (LA), Western Europe (WE), Central/Eastern Europe and Russia (CEER), and Asia-Pacific (AP). We compared regions using descriptive statistics and multivariable regression models. Among the 19 959 patients included, 4066 (23.1%) had HFmrEF and 15 353 (76.9%) HFpEF. Regardless of HF phenotype, patients from WE were oldest, and those in CEER youngest. LA had the largest portion of females and NA most black patients. Obesity and diabetes were most prevalent in NA and hypertension and coronary heart disease most common in CEER. Self-reported health status varied strikingly and was the worst in NA and best in AP. Among patients with HFmrEF, rates of the primary composite endpoint (cardiovascular death or HF hospitalization) were: NA 12.56 per 100 patient-years (/100py), AP 11.67/100py, CEER 10.12/100py, LA 8.90/100py, and WE 8.43/100py, driven by differences in the rate of HF hospitalization. The corresponding values in HFpEF were 11.47/100py, 7.80/100py, 5.47/100py, 5.92/100py, and 7.80/100py, respectively. CONCLUSIONS: There is substantial geographic variation in patient characteristics, treatment and outcomes among patients with HFpEF and HFmrEF. These findings have implications for interpretation and generalizability of trial results, design and conduct of future trials, and optimization of care for these patients.

Examining the Nutrition of Cardiological Patients in Hospitals: Evaluating the Discrepancy between Received Diets and Reference Diet Based on ESC 2021 Guidelines-Hospital Diet Medical Investigation) (HDMI) Study.

Cardiovascular diseases (CVDs) are the leading causes of death worldwide. CVDs have become the dominant cause of death and have been a significant health challenge since the second half of the 20th century in the Polish population. The aim of our HDMI (hospital diet medical investigation) study was to examine the quality of the hospital diets given to cardiac patients and assess how much they adhere to the European Society of Cardiology (ESC) 2021 guidelines. By comparing the diets received by patients with the recommended dietary patterns outlined in the ESC 2021 guidelines, we sought to identify discrepancies. The study was conducted in two steps: creating a 7-day model menu and comparing it with the received diets and then making comparisons with ESC 2021 guidelines. Additionally, we designed a survey to obtain the characteristics of the hospitals. The results show that the nutrition in hospitals remains substandard. None of the diets had an appropriate salt supply or predominance of plant-based food patterns. Only 1/7 diets avoided sweetened beverages, and 2/7 diets had an appropriate amount of fiber. This underscores a gap in the healthcare system to improve patients' health by implementing dietary interventions that foster the development of healthy eating habits.

Impact of COVID-19 in patients with heart failure with mildly reduced or preserved ejection fraction enrolled in the DELIVER trial.

AIM: COVID-19 may affect clinical risk in patients with heart failure. DELIVER began before and was conducted during the COVID-19 pandemic. This study aimed to evaluate the association between COVID-19 and clinical outcomes among DELIVER participants. METHODS AND RESULTS: Participants with chronic heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) were randomized to dapagliflozin or placebo across 350 sites in 20 countries. COVID-19 was investigator-reported and the contribution of COVID-19 to death was centrally adjudicated. We assessed (i) the incidence of COVID-19, (ii) event rates before/during the pandemic, and (iii) risks of death after COVID-19 diagnosis compared to risks of death in participants without COVID-19. Further, we performed a sensitivity analysis assessing treatment effects of dapagliflozin vs. placebo censored at pandemic onset. Of 6263 participants, 589 (9.4%) developed COVID-19, of whom 307 (52%) required/prolonged hospitalization. A total of 155 deaths (15% of all deaths) were adjudicated as definitely/possibly COVID-19-related. COVID-19 cases and deaths did not differ by randomized assignment. Death rate in the 12 months following diagnosis was 56.1 (95% confidence interval [CI] 48.0-65.6) versus 6.4 (95% CI 6.0-6.8)/100 participant-years among trial participants with versus without COVID-19 (adjusted hazard ratio [aHR] 8.60, 95% CI 7.18-10.30). Risk was highest 0-3 months following diagnosis (153.5, 95% CI 130.3-180.8) and remained elevated at 3-6 months (12.6, 95% CI 6.6-24.3/100 participant-years). After excluding investigator-reported fatal COVID-19 events, all-cause death rates in the 12 months following diagnosis among COVID-19 survivors (n = 458) remained higher (aHR 2.46, 95% CI 1.83-3.33) than rates for all trial participants from randomization, with censoring of participants who developed COVID-19 at the time of diagnosis. Dapagliflozin reduced cardiovascular death/worsening HF events when censoring participants at COVID-19 diagnosis (HR 0.81, 95% CI 0.72-0.91) and pandemic onset (HR 0.72, 95% CI 0.58-0.89). There were no diabetic ketoacidosis or major hypoglycaemic events within 30 days of COVID-19. CONCLUSION: DELIVER is one of the most extensive experiences with COVID-19 of any cardiovascular trial, with >75% of follow-up time occurring during the pandemic. COVID-19 was common, with >50% of cases leading to hospitalization or death. Treatment benefits of dapagliflozin persisted when censoring at COVID-19 diagnosis and pandemic onset. Patients surviving COVID-19 had a high early residual risk. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03619213.

The role of pneumococcal vaccination in reducing cardiovascular risk in cardiac patients: Expert opinion of the Prevention Committee of the Polish Cardiac Society supported by the Polish Vaccinology Society.

Respiratory diseases have been the fourth most common cause of death in Poland in recent years. Respiratory infection, especially pneumonia, can lead to exacerbation of chronic cardiovascular disease.Streptococcus pneumoniae is the most common bacterial pathogen causing community-acquired pneumonia. Pneumococci are also the most common pathogen complicating the course of infection with the influenza virus. Pneumonia, especially invasive pneumococcal disease, is associated with risk of death in the course of respiratory failure or sepsis and also with worsening of the prognosis for existing cardiovascular disease. Despite those facts, recommendations for pneumococcal vaccination are still not well established in cardiovascular guidelines. This expert opinion aims to summarize current knowledge on the importance of preventing invasive pneumococcal disease in cardiac patients.

Pharmacotherapy of heart failure A.D. 2023. Expert opinion of Working Group on Cardiovascular Pharmacotherapy, Polish Cardiac Society.

Heart failure (HF) remains one of the most common causes of hospitalization and mortality among Polish patients. The position of the Section of Cardiovascular Pharmacotherapy presents the currently applicable options for pharmacological treatment of HF based on the latest European and American guidelines from 2021-2022 in relation to Polish healthcare conditions. Treatment of HF varies depending on its clinical presentation (acute/chronic) or left ventricular ejection fraction. Initial treatment of symptomatic patients with features of volume overload is based on diuretics, especially loop drugs. Treatment aimed at reducing mortality and hospitalization should include drugs blocking the renin-angiotensin-aldosterone system, preferably angiotensin receptor antagonist/neprilysin inhibitor, i.e. sacubitril/valsartan, selected beta-blockers (no class effect - options include bisoprolol, metoprolol succinate, or vasodilatory beta-blockers - carvedilol and nebivolol), mineralocorticoid receptor antagonist, and sodium-glucose cotransporter type 2 inhibitor (flozin), constituting the 4 pillars of pharmacotherapy. Their effectiveness has been confirmed in numerous prospective randomized trials. The current HF treatment strategy is based on the fastest possible implementation of all four mentioned classes of drugs due to their independent additive action. It is also important to individualize therapy according to comorbidities, blood pressure, resting heart rate, or the presence of arrhythmias. This article emphasizes the cardio- and nephroprotective role of flozins in HF therapy, regardless of ejection fraction value. We propose practical guidelines for the use of medicines, profile of adverse reactions, drug interactions, as well as pharmacoeconomic aspects. The principles of treatment with ivabradine, digoxin, vericiguat, iron supplementation, or antiplatelet and anticoagulant therapy are also discussed, along with recent novel drugs including omecamtiv mecarbil, tolvaptan, or coenzyme Q10 as well as progress in the prevention and treatment of hyperkalemia. Based on the latest recommendations, treatment regimens for different types of HF are discussed.

Hyponatraemia and changes in natraemia during hospitalization for acute heart failure and associations with in-hospital and long-term outcomes - from the ESC-HFA EORP Heart Failure Long-Term Registry.

AIMS: To comprehensively assess hyponatraemia in acute heart failure (AHF) regarding prevalence, associations, hospital course, and post-discharge outcomes. METHODS AND RESULTS: Of 8298 patients in the European Society of Cardiology Heart Failure Long-Term Registry hospitalized for AHF with any ejection fraction, 20% presented with hyponatraemia (serum sodium <135 mmol/L). Independent predictors included lower systolic blood pressure, estimated glomerular filtration rate (eGFR) and haemoglobin, along with diabetes, hepatic disease, use of thiazide diuretics, mineralocorticoid receptor antagonists, digoxin, higher doses of loop diuretics, and non-use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and beta-blockers. In-hospital death occurred in 3.3%. The prevalence of hyponatraemia and in-hospital mortality with different combinations were: 9% hyponatraemia both at admission and discharge (hyponatraemia Yes/Yes, in-hospital mortality 6.9%), 11% Yes/No (in-hospital mortality 4.9%), 8% No/Yes (in-hospital mortality 4.7%), and 72% No/No (in-hospital mortality 2.4%). Correction of hyponatraemia was associated with improvement in eGFR. In-hospital development of hyponatraemia was associated with greater diuretic use and worsening eGFR but also more effective decongestion. Among hospital survivors, 12-month mortality was 19% and adjusted hazard ratios (95% confidence intervals) were for hyponatraemia Yes/Yes 1.60 (1.35-1.89), Yes/No 1.35 (1.14-1.59), and No/Yes 1.18 (0.96-1.45). For death or heart failure hospitalization they were 1.38 (1.21-1.58), 1.17 (1.02-1.33), and 1.09 (0.93-1.27), respectively. CONCLUSION: Among patients with AHF, 20% had hyponatraemia at admission, which was associated with more advanced heart failure and normalized in half of patients during hospitalization. Admission hyponatraemia (possibly dilutional), especially if it did not resolve, was associated with worse in-hospital and post-discharge outcomes. Hyponatraemia developing during hospitalization (possibly depletional) was associated with lower risk.

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.

IGFBP-7 and Outcomes in Heart Failure With Reduced Ejection Fraction: Findings From DAPA-HF.

BACKGROUND: Insulin-like growth factor-binding protein-7 (IGFBP-7) has been proposed as a potential prognostic biomarker in heart failure (HF), but the association between elevation in IGFBP-7 and HF outcomes in ambulant patients with heart failure with reduced ejection fraction (HFrEF) is unknown. OBJECTIVES: The authors addressed this question in a post hoc analysis of the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial. METHODS: The primary outcome was a composite of cardiovascular death or a worsening HF event. The risk of adverse outcome was compared across tertiles of IGFBP-7 concentration by means of Cox proportional hazard models adjusted for N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (hsTnT). The efficacy of randomized treatment across IGFBP-7 tertiles was assessed. Change in IGFBP-7 at 12 months was compared with the use of geometric means. RESULTS: A total of 3,158 patients had IGFBP-7 measured at baseline, and 2,493 had a repeated measure at 12 months. Patients in the highest tertile of IGFBP-7 had evidence of more advanced HFrEF. The adjusted HR for the primary endpoint in tertile 3, compared with tertile 1, was 1.48 (95% CI: 1.17-1.88). There was no modification of the benefit of dapagliflozin by baseline IGFBP-7 (P interaction = 0.34). Dapagliflozin did not change IGFBP-7 levels over 1 year (P = 0.34). CONCLUSIONS: Higher IGFBP-7 in patients with HFrEF was associated with worse clinical profile and an increased risk of adverse clinical outcomes. IGFBP-7 provided prognostic information incremental to clinical variables, NT-proBNP, and hsTnT. The benefit of dapagliflozin was not modulated by IGFBP-7 level.

Inhibitors of sodium-glucose transport protein 2: A new multidirectional therapeutic option for heart failure patients.

Several mechanisms have been suggested to explain positive cardiovascular effects observed in studies with sodium-glucose co-transporter 2 (SGLT2) inhibitors. The reduction in glucose reabsorption in proximal tubuli induced by SGLT2 inhibitors increases urinary glucose and sodium excretion resulting in increased osmotic diuresis and consequently in decreased plasma volume, followed by reduced preload. In addition, the hemodynamic effects of SGLT2 inhibition were observed in both hyper and euglycemic patients. Due to the complex and multidirectional effects induced by SGLT2 inhibitors, this originally antidiabetic group of drugs has been successfully used to treat patients with heart failure as well as for subjects with chronic kidney disease. Moreover, their therapeutic potential seems to be even broader than the indications studied to date.

Association between sacubitril/valsartan initiation and changes in left ventricular ejection fraction: Insights from ARIADNE registry.

AIMS: We tested the hypothesis that initiation versus non-initiation of sacubitril/valsartan is associated with a more favorable subsequent change in left ventricular ejection fraction (LVEF) in a real-world setting. METHODS: A prospective, non-randomized, double-arm, open-label, cohort study had been conducted across 687 centers in 17 European countries enrolling HFrEF patients aged ≥18 years with symptoms of HF (New York Heart Association [NYHA] II-IV) and "reduced LVEF". For the current analysis, 2602 patients with LVEF measured at baseline and follow-up were chosen, of which 860 (33%, mean age 67 years, 26% women) were started on sacubitril/valsartan at baseline and 1742 (67%, 68 years, 23% women) were not. Patients started on sacubitril/valsartan had higher NYHA class and lower LVEF. RESULTS: LVEF increased from mean 32.7% to 38.1% in the sacubitril/valsartan group versus from 35.9% to 38.7% in the non-sacubitril/valsartan group (mean difference in increase 2.6%, p < 0.001). LVEF increased from baseline in 64% versus 53% of patients and increased by ≥5% (absolute %) in 50% versus 35% of patients in the sacubitril/valsartan versus non-sacubitril/valsartan groups, respectively. In the overall cohort, initiation of sacubitril/valsartan was independently associated with any increase in LVEF (adjusted odds ratio [OR] 1.49 [1.26-1.75]) and with increase by ≥5% (OR 1.65 [1.39-1.95]). CONCLUSION: Initiating versus not initiating sacubitril/valsartan was independently associated with a greater subsequent increase in LVEF in this real-world setting. Reverse cardiac remodeling may be one mechanism of benefit of sacubitril/valsartan.
