Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study.

AIMS: We aimed to determine the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and to identify clinical factors associated with their use in patients with heart failure (HF) in a real-life setting. METHODS: Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study is a multicentre, cross-sectional and observational study that included HF patients in the outpatient setting regardless of ejection fraction from 19 cardiology centres between August 2023 and December 2023. RESULTS: The study population consisted of 1923 patients with HF, predominantly men (61.2%), with a median age of 66 (range: 19-101) years. Overall, 925 patients (48.1%) were receiving SGLT2is. Among the study population, 22.1% had HF with preserved ejection fraction, 21.5% had HF with mildly reduced ejection fraction, 56.4% had HF with reduced ejection fraction and the use of SGLT2is was 42.0%, 47.9% and 50.6% in each group, respectively (P = 0.012). The use of SGLT2is was 76.6% in patients with HF and diabetes, 19.8% in patients with HF and chronic kidney disease and 26.8% in patients without diabetes and chronic kidney disease (P < 0.001). Higher education level [odds ratio (OR): 1.80; 95% confidence interval (CI): 1.06-3.05; P = 0.027], higher household income (OR: 3.46; 95% CI: 1.27-9.42; P = 0.015), New York Heart Association functional class IV (OR: 2.72; 95% CI: 1.16-6.35; P = 0.021), diabetes (OR: 9.42; 95% CI: 6.72-13.20; P < 0.001), the use of angiotensin receptor-neprilysin inhibitors (ARNis) (OR: 4.09; 95% CI: 2.39-7.01; P < 0.001), the use of mineralocorticoid receptor antagonists (MRAs) (OR: 2.02; 95% CI: 1.49-2.75; P < 0.001), the use of loop diuretics (OR: 1.62; 95% CI: 1.18-2.22; P = 0.003) and the use of thiazide diuretics (OR: 1.72; 95% CI: 1.30-2.29; P < 0.001) were independently associated with the use of SGLT2is. Conversely, atrial fibrillation (OR: 0.63; 95% CI: 0.45-0.88; P = 0.008), chronic kidney disease (OR: 0.53; 95% CI: 0.37-0.76; P = 0.001), the use of dihydropyridine calcium channel blockers (OR: 0.68; 95% CI: 0.48-0.98; P = 0.042) and the use of statins (OR: 0.67; 95% CI: 0.49-0.91; P = 0.010) were independently associated with the non-use of SGLT2is. CONCLUSIONS: The RED-HEART study provided comprehensive real-world data about implementing SGLT2is in patients with HF. These results suggest that there is a need for organized action and close collaboration between healthcare providers to improve the implementation of SGLT2is, especially in patients with HF with preserved ejection fraction and chronic kidney disease.

Association of Pan Immune-Inflammation Value with Long Term Outcomes of Acute Decompensated Heart Failure. / Associação do Valor Pan-Imune-Inflamatório com Desfechos de Longo Prazo na Insuficiência Cardíaca Agudamente Descompensada.

BACKGROUND: Although there have been significant improvements in the treatment of heart failure (HF) in recent decades, its prognosis remains poor. Although there are many biomarkers that can help predict the prognosis of patients with HF, there is a need for simpler, cheaper, and more easily available biomarkers. OBJECTIVE: To evaluate the predictive value of pan-immune-inflammation value (PIV) in patients with acute decompensated HF. METHODS: We analyzed 409 patients with HF with reduced ejection fraction who were hospitalized for acute decompensated HF. Patients were divided into 3 groups according to tertiles of PIV: tertile 1 (PIV < 357.25), tertile 2 (PIV ≥ 357.25 and < 834.55), and tertile 3 (PIV ≥ 834.55). P values < 0.05 were considered statistically significant. Kaplan-Meier curves and Cox proportional hazards regression models were used to evaluate the association between PIV and all-cause mortality. The primary outcome was 5-year all-cause mortality, and the secondary outcomes were in-hospital 30 days,, 180-day, and 1-year all-cause mortality. RESULTS: We showed that higher PIV value was associated with both primary and secondary outcomes. The Kaplan-Meier curve showed that patients with higher PIV values had an increased risk of short- and long-term all-cause mortality (log-rank p < 0.001). In the multivariate analysis, PIV was identified as an independent predictor of long-term all-cause mortality in patients with acute decompensated HF, and we observed a 1.96-fold increase in the hazard of an event (odds ratio: 1.96, 95% confidence interval: 1.330 to 2.908, p = 0.001). CONCLUSIONS: Our study showed that the novel biomarker PIV can be used as a predictor of prognosis in patients with acute decompensated HF.

FUNDAMENTO: Embora tenha havido melhorias significativas no tratamento da insuficiência cardíaca (IC) nas últimas décadas, seu prognóstico permanece desfavorável. Embora existam muitos biomarcadores que podem ajudar a prever o prognóstico de pacientes com IC, há necessidade de biomarcadores mais simples, menos dispendiosos e mais facilmente disponíveis. OBJETIVO: Avaliar o valor preditivo do valor pan-imune-inflamatório (PIV, do inglês pan-immune-inflammation value) em pacientes com IC agudamente descompensada. MÉTODOS: Analisamos 409 pacientes com IC com fração de ejeção reduzida internados por IC aguda descompensada. Os pacientes foram divididos em 3 grupos de acordo com os tercis de PIV: tercil 1 (PIV < 357,25), tercil 2 (PIV ≥ 357,25 e < 834,55) e tercil 3 (PIV ≥ 834,55). Foram considerados estatisticamente significativos valores de p < 0,05. Curvas de Kaplan-Meier e modelos de regressão de riscos proporcionais de Cox foram utilizados para avaliar a associação entre PIV e mortalidade por todas as causas. O desfecho primário foi mortalidade por todas as causas em 5 anos, e o desfecho secundário compreendeu a mortalidade por todas as causas intra-hospitalar em 30 dias, em 180 dias e em 1 ano. RESULTADOS: Mostramos que valores mais elevados de PIV estavam associados a desfechos primários e secundários. A curva de Kaplan-Meier mostrou que pacientes com valores mais elevados de PIV apresentaram risco aumentado de mortalidade por todas as causas em curto e longo prazo (log-rank p < 0,001). Na análise multivariada, o PIV foi identificado como um preditor independente de mortalidade por todas as causas em longo prazo em pacientes com IC aguda descompensada, e observamos um aumento de 1,96 vezes no risco de um evento (razão de chances: 1,96; intervalo de confiança de 95%: 1,330 a 2,908; p = 0,001). CONCLUSÕES: Nosso estudo mostrou que o novo biomarcador PIV pode ser usado como preditor de prognóstico em pacientes com IC aguda descompensada.

Ticagrelor Induced Cheyne-Stokes Respiration and Asystolic Ventricular Standstill: A Case Report.

Ticagrelor is a potent, direct-acting, and reversible P2Y12­adenosine diphosphate receptor blocker. It has a rapid onset of action and an intense and consistent platelet reactivity inhibition that has been demonstrated to be superior to clopidogrel in decreasing major adverse events in acute coronary syndrome (ACS). Although ticagrelor is well tolerated in ACS patients, it has side effects, such as dyspnea and bradyarrhythmia, as reported in the Platelet Inhibition and Patient Outcomes (PLATO) study. Furthermore, it was reported that ticagrelor's bradyarrhythmic potential was transient and not clinically significant beyond the acute initiation phase. Nor was there a difference in rates of syncope or need for pacemaker insertion during 30 days of follow-up. Here we report a case of ticagrelor associated with Cheyne-Stokes respiration and asystolic ventricular standstill in a patient with ACS who required resuscitation and insertion of a temporary pacemaker.

Comparison of artificial intelligence-assisted informed consent obtained before coronary angiography with the conventional method: Medical competence and ethical assessment.

Objective: At the time of informed consent (IC) for coronary angiography (CAG), patients' knowledge of the process is inadequate. Time constraints and a lack of personalization of consent are the primary causes of inadequate information. This procedure can be enhanced by obtaining IC using a chatbot powered by artificial intelligence (AI). Methods: In the study, patients who will undergo CAG for the first time were randomly divided into two groups, and IC was given to one group using the conventional method and the other group using an AI-supported chatbot, chatGPT3. They were then evaluated with two distinct questionnaires measuring their satisfaction and capacity to understand CAG risks. Results: While the satisfaction questionnaire was equal between the two groups (p = 0.581), the correct understanding of CAG risk questionnaire was found to be significantly higher in the AI group (<0.001). Conclusions: AI can be trained to support clinicians in giving IC before CAG. In this way, the workload of healthcare professionals can be reduced while providing a better IC.

Door to Balloon Time of Non-ST Elevation Myocardial Infarction May be Reconsidered According to Systemic Immune-Inflammation Index.

Aim    Early diagnosis and treatment is very important in acute coronary syndromes (ACS). Previous studies showed that not all non-ST elevation myocardial infarction (NSTEMI) patients should be considered and treated in the same way. The systemic immune-inflammation index (SII), which is an easily accessible, rapidly computed, and cost-effective parameter, was evaluated in this study to determine the optimal intervention time for NSTEMI.Material and methods    469 patients diagnosed with ACS were included to the study. STEMI and NSTEMI patients were compared according to their SII. Univariate and binary logistic regression analysis were performed to determine which parameters have a significant effect on the discrimination of types of myocardial infarction.Results    The mean age of the patients was 61.43±11.52 yrs, and 348 (74.2 %) were male. NSTEMI patients with an SII value higher than 768×109 / l may be assumed to be STEMI (p<0.001). Univariate analysis and binary logistic regression showed that only SII and hypertension had statistically impact on differentiation of STEMI and NSTEMI. In addition, SII value of 1105×109 / l was the cut-off point for discrimination of cardiovascular survival (p<0.001, AUC =0.741). This study was performed to find out which NSTEMI patients should be treated percutaneously immediately after first medical contact according to SII. It was found that, SII value of higher than 768×109 / l is related with STEMI.Conclusion    In conclusion, NSTEMI patients with a SII value higher than 768×109 / l may be considered as STEMI and treated with in 120 min after first contact. In addition, SII was found to be a cardiovascular mortality predictor after myocardial infarction, and this may be used for identifying high-risk patients after percutaneous coronary intervention.

Real-World Evaluation of Anticoagulant Treatment Patterns in Patients with Atrial Fibrillation: Data from Multicenter ROTA Study.

OBJECTIVE: Oral anticoagulant therapy is the cornerstone of atrial fibrillation management to prevent stroke and systemic embolism. However, there is limited real-world information regarding stroke and systemic embolism prevention strategies in patients with atrial fibrillation. The aim of the ROTA study is to obtain the real-world data of anticoagulant treatment patterns in patients with atrial fibrillation. METHODS: The ROTA study is a prospective, multicenter, and observational study that included 2597 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January 2021 and May 2021. RESULTS: The median age of the study population was 72 years (range: 22-98 years) and 57.4% were female. The median CHA2DS2-VASc and HAS-BLED scores were 4 (range: 0-9) and 1 (range: 0-6), respectively. Vitamin K antagonists and direct oral anticoagulants were used in 15.9% and 79.4% of patients, respectively. The mean time in therapeutic range was 52.9% for patients receiving vitamin K antagonists, and 76% of those patients had an inadequate time in therapeutic range with <70%. The most common prescribed direct oral anticoagulants were rivaroxaban (38.1%), apixaban (25.5%), and edoxaban (11.2%). The rate of overuse of vitamin K antagonists and direct oral anticoagulants was high (76.1%) in patients with low stroke risk, and more than one-fourth of patients on direct oral anticoagulant therapy were receiving a reduced dose of direct oral anticoagulants. Among patients who were on direct oral anticoagulant treatment, patients with apixaban treatment were older, had higher CHA2DS2-VASc and HAS-BLED scores, and had lower creatinine clearance than the patients receiving other direct oral anticoagulants. CONCLUSIONS: The ROTA study provides important real-world information about anticoagulant treatment patterns in patients with atrial fibrillation.time in therapeutic range with <70%.

Relationship between left atrial functions and ambulatory blood pressure variability in patients with heart failure and preserved ejection fraction.

Aim    The aim of this study was to investigate the relationship between left atrial (LA) abnormalities and ambulatory blood pressure variability (BPV) in heart failure with preserved ejection fraction (HFpEF) patients.Material and methods    In this single-center, prospective study, we included 187 patients with HFpEF. Eighteen patients with poor image quality were excluded from the study. BPV was evaluated using 24-h ambulatory blood pressure (BP) monitoring. The standard deviation of systolic BP (SBP-SD) was calculated to assess BPV. The patients were classified into two groups according to median SBP-SD (10.5 mm Hg).Results    Overall, 169 HFpEF patients (69.2% women, mean age 69.2±11 yrs) were evaluated. There were 98 patients (57.9%) with a SBP-SD greater than 10.5 mm Hg. Patients with higher SPB-SD had significantly higher left atrial stiffness (LASt) and lower LA reservoir strain (LASr) than those with low SPB-SD. LASt was correlated with 24 hr SBP-SD in both sinus rhythm (r= 0.35, p= 0.015) and atrial fibrillation patients (r= 0.32, p= 0.005). There were significant correlations between night-time SBP-SD and LASr (r=-0.23, p=0.045) in HFpEF with sinus rhythm. For all HFpEF patients, multiple regression analyses showed that 24-hr SBP-SD was correlated with LASt (coeff.=0.40, 95%CI= 0.52-5.25, P= 0.017).Conclusions    High BPV is associated with impaired LA function, especially for LASt and LASr. This study may provide insight for larger multicenter studies to evaluate the effects on outcomes in HFpEF.

Left atrial structure and function: association with blood pressure variability in pregnant women.

BACKGROUND: The aim of this study was to investigate the relationship between left atrial (LA) abnormalities and ambulatory blood pressure variability (BPV) in pregnant women and their relationship with hypertension-related clinical outcomes in pregnancy. METHODS: This single-center, prospective study included 119 pregnant women. All participants underwent 24-h ambulatory blood pressure (BP) monitoring and echocardiographic examination before 20 weeks of gestation. BPV was evaluated using 24-h ambulatory BP monitoring. SD of the mean of SBP (SBP-SD) and DBP variability was calculated as 24-h, daytime and nighttime SBP and DBP. The patients were classified into two groups based on median 24-h SBP-SD (11.3 mmHg). LA features of the patients were compared according to the high and low BPV groups. RESULTS: One hundred and nineteen pregnant women (mean age, 28.6 ± 5.2 years) were included in the study. The mean office SBP and DBP were 108.7 ± 15.4 mmHg and 68.2 ± 10.2 mmHg, respectively. In pregnant women with high BPV, even though BP is normal, reservoir and conduit LA functions have decreased and LA stiffness has increased. Gestational hypertension and composite outcomes were more common in pregnant women with high BPV. Among the LA parameters, the most associated with composite outcome was conduit LA function. CONCLUSION: In pregnancy, higher BPV is associated with worse LA function. The LA conduit strain offers potential value in predicting hypertension-related clinical outcomes in pregnancy.

Comparison of pan-immune-inflammation value with other inflammation markers of long-term survival after ST-segment elevation myocardial infarction.

BACKGROUND: Atherosclerosis is a process that causes coronary artery disease and is associated with the inflammatory response. In this study, we aimed to evaluate the association of Pan-Immune-Inflammation Value (PIV) with in-hospital and long-term mortality in STEMI patients. METHODS: A total of 658 patients who were admitted to the emergency department of two tertiary centers with the diagnosis of STEMI and underwent percutaneous coronary intervention (PCI) between 2018 and 2022 were retrospectively enrolled. PIV and other inflammation parameters were compared for the study population. The primary outcome was one-year all-cause of mortality. RESULTS: The mean age was 58.7 ± 17.1 years and 507 (76.9%) were male. The mean duration of the follow-up was 18.8 ± 8.5 months (median 18.9 months). PIV was superior to the neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and systemic immune-inflammation index for the prediction of primary and secondary outcomes in STEMI. CONCLUSION: Our study reveals that PIV is a better predictor of mortality in STEMI patients. Prospective studies are needed to validate this biomarker.

Association between Pfizer-BioNTech mRNA vaccine and myocardial infarction: clinical and angiographic insights.

OBJECTIVE: With the widespread administration of the BioNTech mRNA-based COVID-19 vaccine, there is a need to evaluate its potential effects on cardiovascular health, particularly its association with myocardial infarction (MI). This study aimed to investigate the relationship between BioNTech vaccination and MI, as well as its impact on clinical and angiographic parameters. METHODS: A retrospective analysis was conducted at the Eskisehir Osmangazi University, Eskisehir City Hospital, between April 2020 and May 2023 on a cohort of 1 151 patients hospitalised with MI. The patients were stratified into a BioNTech+ (vaccinated) and a BioNTech- (unvaccinated) groups. Medical records were reviewed for demographic information, clinical data and angiographic findings. Statistical analyses were performed, including logistic regression models adjusting for potential confounders. RESULTS: The BioNTech- group had a higher mean number of percutaneous transluminal coronary angioplasty procedures and stents compared to the BioNTech+ group. Haematological parameters and lipid profiles showed some discrepancies between the two groups. The BioNTech- group had higher white blood cell and platelet counts, while also exhibiting a higher mean low-density lipoprotein cholesterol level. The prevalence of co-morbidities and cardiovascular risk factors differed between the groups. CONCLUSION: This study found associations between the BioNTech vaccination and clinical and angiographic parameters in patients with MI.

PrevAleNce and Associated factors of inappropriaTe dosing of direct Oral anticoaguLants In pAtients with Atrial Fibrillation: the ANATOLIA-AF Study.

PURPOSE: Inappropriate dosing of direct oral anticoagulants is associated with an increased risk of stroke, systemic embolism, major bleeding, cardiovascular hospitalization, and death in patients with atrial fibrillation. The main goal of the study was to determine the prevalence and associated factors of inappropriate dosing of direct oral anticoagulants in real-life settings. METHODS: This study was a multicenter, cross-sectional, observational study that included 2004 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January and May 2021. The main criteria for inappropriate direct oral anticoagulant dosing were defined according to the recommendations of the European Heart Rhythm Association. RESULTS: The median age of the study population was 72 years and 58% were women. Nine-hundred and eighty-seven patients were prescribed rivaroxaban, 658 apixaban, 239 edoxaban, and 120 dabigatran. A total of 498 patients (24.9%) did not receive the appropriate dose of direct oral anticoagulants. In a logistic regression model, advanced age, presence of chronic kidney disease and permanent atrial fibrillation, prescription of reduced doses of direct oral anticoagulants or edoxaban treatment, concomitant use of amiodarone treatment, and non-use of statin treatment were significantly associated with potentially inappropriate dosing of direct oral anticoagulants. CONCLUSION: The study demonstrated that the prevalence of inappropriate direct oral anticoagulant dosing according to the European Heart Rhythm Association recommendations was 24.9% in patients with atrial fibrillation. Several demographic and clinical factors were associated with the inappropriate prescription of direct oral anticoagulants.

Comparison of long-term outcome of patients with ST-segment elevation myocardial infarction between pre-COVID-19 and COVID-19 era.

AIMS: To compare major cardiovascular and cerebrovascular events (MACCE) rates between patients in the pre-COVID-19 era and COVID-19 era, and to assess the impact of the presence of COVID-19 (+) on long-term MACCE in ST-segment elevation myocardial infarction (STEMI) in Turkey. METHODS: Using the TURSER study (TURKISH ST-segment elevation myocardial infarction registry) data, the current study included 1748 STEMI patients from 15 centres in Turkey. Patients were stratified into COVID-19 era (March 11st-May 15st, 2020; n = 723) or pre-COVID-19 era (March 11st-May 15st, 2019; n = 1025) cohorts. Long-term MACCE rates were compared between groups. In addition, the effect of COVID-19 positivity on long-term outcomes was evaluated. The primary outcome was the occurrence of MACCE at long-term follow-up, and the secondary outcome was hospitalization with heart failure. RESULTS: The MACCE and hospitalization with heart failure rates between pre-COVID-19 era and COVID-19 era were 23% versus 22% (p = .841), and 12% versus 8% (p = .002), respectively. In the COVID-19 era, the rates of MACCE and hospitalization with heart failure COVID-19-positive versus COVID-19-negative patients were 40% versus 20%, (p < .001), and 43% versus 11% (p < .001), respectively. CONCLUSION: There was no difference between the pre-COVID-19 era and the COVID-19 era in terms of MACCE  in STEMI patients in Turkey. In the COVID-19 era, STEMI patients positive for COVID-19 had a higher rate of MACCE and heart failure hospitalization at the long-term follow-up.

Clinical characteristics and in-hospital outcomes of COVID-19 patients with history of heart failure: a propensity score-matched study.

BACKGROUND: Data on the clinical course and outcomes of COVID-19 disease among patients with a history of heart failure (HF) are scarce. Therefore, the aim of this study was to assess the clinical characteristics, prognostic biomarkers and in-hospital outcomes of patients with a history of HF hospitalised with confirmed COVID-19. METHODS: A total of 8321 consecutive patients hospitalised with suspected COVID-19 disease were screened. Furthermore, 3849 patients with laboratory-confirmed SARS-CoV-2 infection were included in the study. Two hundred and forty COVID-19 patients with a history of HF and 240 without HF paired with PSM were evaluated. RESULTS: Mean age was 72.7 ± 9.90 years, and 64.6% were men. Oxygen saturation, systolic and diastolic blood pressure at admission were significantly lower and heart rate was significantly higher in patients with a history of HF compared to those without. Patients with HF, compared to those without, had significantly higher leukocyte count, D-dimer, CRP, procalcitonin, hsTnI, lactate and lower albumin and lymphocyte. Compared with patients without HF, those with previous HF had a longer length of stay at ICU (6.22 d vs. 3.71 d; p < 0.001), increased risk of mechanical ventilation (42.1% vs. 15.4%; p < 0.001), in-hospital death (39.2% vs. 15.4%; p < 0.001) and composite outcomes (52.9% vs. 17.1%; p < 0.001). CONCLUSION: History of HF is associated with a higher risk of mechanical ventilation, cardiogenic shock, mortality and longer ICU stay in patients hospitalised for COVID-19, therefore the diagnosis of HF alone is important for predicting clinical outcomes.
