ABSTRACT
Background: Landiolol, a highly cardioselective agent with a short half-life (2.4-4 min), is commonly used as a perfusor or bolus application to treat tachycardic arrhythmia. Some small studies suggest that prior oral ß-blocker use results in a less effective response to intravenous ß-blockers. Methods: This study investigated whether prior chronic oral ß-blocker (Lß) or no prior chronic oral ß-blocker (L-) intake influences the response to intravenous push-dose Landiolol in intensive care patients with acute tachycardic arrhythmia. Results: The effects in 30 patients (67 [55-72] years) were analyzed, 10 (33.3%) with and 20 (66.7%) without prior oral ß-blocker therapy. Arrhythmias were diagnosed as tachycardic atrial fibrillation in 14 patients and regular, non-fluid-dependent, supraventricular tachycardia in 16 cases. Successful heart rate control (Lß 4 vs. L- 7, p = 1.00) and rhythm control (Lß 3 vs. L- 6, p = 1.00) did not significantly differ between the two groups. Both groups showed a significant decrease in heart rate when comparing before and after the bolus administration, without significant differences between the two groups (Lß -26/min vs. L- -33/min, p = 0.528). Oral ß-blocker therapy also did not influence the change in mean arterial blood pressure after Landiolol bolus administration (Lß -5 mmHg vs. L- -4 mmHg, p = 0.761). Conclusions: A prior chronic intake of ß-blockers neither affected the effectiveness of push-dose Landiolol in heart rate or rhythm control nor impacted the difference in heart rate or mean arterial blood pressure before and after the Landiolol boli.
ABSTRACT
BACKGROUND: Out-of-hospital cardiac arrest (OHCA) complicated by refractory ventricular fibrillation (VF) is associated with poor outcome. Beta-1-receptor selective blockade might overcome refractory VF and improve survival. This trial investigates the efficacy and safety of prehospital landiolol in OHCA and refractory VF. METHODS: In this randomized, double-blind, placebo-controlled pilot trial, patients with OHCA and recurrent or refractory VF (at least 3 defibrillation attempts and last rhythm shockable), pretreated with epinephrine and amiodarone, were allocated to receive add-on treatment with landiolol or placebo. Landiolol was given as a 20 mg bolus infusion. The primary efficacy outcome was time from trial drug infusion to sustained return of spontaneous circulation (ROSC). Safety outcomes included the onset of bradycardia and asystole. RESULTS: A total of 36 patients were enrolled, 19 were allocated to the landiolol group and 17 to the placebo group. Time from trial drug infusion to sustained ROSC was similar between treatment groups (39 min [landiolol] versus 41 min [placebo]). Sustained ROSC was numerically lower in the landiolol group compared with the placebo group (7 patients [36.8%] versus 11 patients [64.7%], respectively). Asystole within 15 min of trial drug infusion occurred significantly more often in the landiolol group than in the placebo group (7 patients [36.8%] and 0 patients [0.0%], respectively). CONCLUSION: In patients with OHCA and refractory VF who are pretreated with epinephrine and amiodarone, add-on bolus infusion of landiolol 20 mg did not lead to a shorter time to sustained ROSC compared with placebo. Landiolol might be associated with bradycardia and asystole.

AIMS: Direct oral anticoagulants (DOACs) are increasingly used off-label to treat patients with left ventricular thrombus (LVT). We analysed available meta-data comparing DOACs and vitamin K antagonists (VKAs) for efficacy and safety. METHODS: We conducted a systematic search and meta-analysis of observational and randomized data comparing DOACs vs. VKAs in patients with LVT. Endpoints of interest were stroke or systemic embolism, thrombus resolution, all-cause death, and a composite bleeding endpoint. Estimates were pooled using a random-effects model meta-analysis, and their robustness was investigated using sensitivity and influential analyses. RESULTS: We identified 22 articles (18 observational studies, 4 small randomized clinical trials) reporting on a total of 3587 patients (2489 VKA vs. 1098 DOAC therapy). The pooled estimates for stroke or systemic embolism [odds ratio (OR): 0.81; 95% confidence interval (CI): 0.57, 1.15] and thrombus resolution (OR: 1.12; 95% CI: 0.86, 1.46) were comparable, and there was low heterogeneity overall across the included studies. The use of DOACs was associated with lower odds of all-cause death (OR: 0.65; 95% CI: 0.46, 0.92) and a composite bleeding endpoint (OR: 0.67; 95% CI: 0.47, 0.97). A risk of bias was evident particularly for observational reports, with some publication bias suggested in funnel plots. CONCLUSION: In this comprehensive analysis of mainly observational data, the use of DOACs was not associated with a significant difference in stroke or systemic embolism, or thrombus resolution, compared with VKA therapy. The use of DOACs was associated with a lower rate of all-cause death and fewer bleeding events. Adequately sized randomized clinical trials are needed to confirm these findings, which could allow a wider adoption of DOACs in patients with LVT.

BACKGROUND: Postoperative atrial fibrillation (POAF) represents the most common complication following cardiac surgery. Approximately one-third of patients experiencing POAF transition to atrial fibrillation within a year, challenging the notion of POAF as merely a transient event. Soluble ST2 (sST2) is an established biomarker regarding fibrosis and myocardial stretch, however, its role in predicting the onset of POAF remains unclear. METHODS: Preoperative sST2 levels have been assessed in 496 individuals with no prior history of AF who underwent elective cardiac surgery, including valve, coronary artery bypass graft surgery, or a combined procedure. RESULTS: The average age was 70 years, and 29.4 % were female. Overall, 42.3 % developed POAF. sST2 levels were found to be significantly higher in patients with POAF. Interestingly, sST2 was only predictive of POAF in females with an adjusted OR of 1.894 (95 %CI:1.103-3.253; p = 0.021) and not males (OR:1.091; 95 %CI:0.849-1.402; p = 0.495). Furthermore, within a linear regression model it was observed that for every 1 ng/mL increase in sST2 levels, the average POAF duration extended by 39.5 min (95 %CI:15.8-63.4 min; p = 0.001). CONCLUSION: sST2 predicts the onset of POAF in women but not men undergoing cardiac surgery. Furthermore, sST2 levels were associated with the subsequent burden of POAF. Thus, assessment of sST2 in addition to clinical risk factors could improve risk stratification for development of POAF following elective cardiac surgery.

BACKGROUND: Strategies to reach out-of-hospital cardiac arrests (called cardiac arrest) in residential areas and reduce disparities in care and outcomes are warranted. This study investigated incidences of cardiac arrests in public housing areas. METHODS: This register-based cohort study included cardiac arrest patients from Amsterdam (the Netherlands) from 2016 to 2021, Copenhagen (Denmark) from 2016 to 2021, and Vienna (Austria) from 2018 to 2021. Using Poisson regression adjusted for spatial correlation and city, we compared cardiac arrest incidence rates (number per square kilometer per year and number per 100â 000 inhabitants per year) in public housing and other residential areas and examined the proportion of cardiac arrests within public housing and adjacent areas (100-m radius). RESULTS: Overall, 9152 patients were included of which 3038 (33.2%) cardiac arrests occurred in public housing areas and 2685 (29.3%) in adjacent areas. In Amsterdam, 635/1801 (35.3%) cardiac arrests occurred in public housing areas; in Copenhagen, 1036/3077 (33.7%); and in Vienna, 1367/4274 (32.0%). Public housing areas covered 42.4 (12.6%) of 336.7 km2 and 1â 024â 470 (24.6%) of 4â 164â 700 inhabitants. Across the capitals, we observed a lower probability of 30-day survival in public housing versus other residential areas (244/2803 [8.7%] versus 783/5532 [14.2%]). The incidence rates and rate ratio of cardiac arrest in public housing versus other residential areas were incidence rate, 16.5 versus 4.1 n/km2 per year; rate ratio, 3.46 (95% CI, 3.31-3.62) and incidence rate, 56.1 versus 36.8 n/100â 000 inhabitants per year; rate ratio, 1.48 (95% CI, 1.42-1.55). The incidence rates and rate ratios in public housing versus other residential areas were consistent across the 3 capitals. CONCLUSIONS: Across 3 European capitals, one-third of cardiac arrests occurred in public housing areas, with an additional third in adjacent areas. Public housing areas exhibited consistently higher cardiac arrest incidences per square kilometer and 100â 000 inhabitants and lower survival than other residential areas. Public housing areas could be a key target to improve cardiac arrest survival in countries with a public housing sector.

Cardiac emergencies in women, such as acute coronary syndromes, acute heart failure, and cardiac arrest, are associated with a high risk of adverse outcomes and mortality. Although women historically have been significantly underrepresented in clinical studies of these diseases, the guideline-recommended treatment for these emergencies is generally the same for both sexes. Still, women are less likely to receive evidence-based treatment compared to men. Furthermore, specific diseases affecting predominantly or exclusively women, such as spontaneous coronary dissection, myocardial infarction with non-obstructive coronary arteries, takotsubo cardiomyopathy, and peripartum cardiomyopathy, require specialized attention in terms of both diagnosis and management. In this clinical consensus statement, we summarize current knowledge on therapeutic management of these emergencies in women. Key statements and specific quality indicators are suggested to achieve equal and specific care for both sexes. Finally, we discuss several gaps in evidence and encourage further studies designed and powered with adequate attention for sex-specific analysis.
ABSTRACT
Although cardiovascular diseases (CVDs) are the leading cause of death worldwide, their pharmacotherapy remains suboptimal. Thus, there is a clear unmet need to develop more effective and safer pharmacological strategies. In this review, we summarize the most relevant advances in cardiovascular pharmacology in 2023, including the approval of first-in-class drugs that open new avenues for the treatment of atherosclerotic CVD and heart failure (HF). The new indications of drugs already marketed (repurposing) for the treatment of obstructive hypertrophic cardiomyopathy, hypercholesterolaemia, type 2 diabetes, obesity, and HF; the impact of polypharmacy on guideline-directed drug use is highlighted as well as results from negative clinical trials. Finally, we end with a summary of the most important phase 2 and 3 clinical trials assessing the efficacy and safety of cardiovascular drugs under development for the prevention and treatment of CVDs.

Quality indicators serve as a tool to measure and improve evidence-based health care. Often the transition from inpatient to outpatient care is not sufficiently included. The focus of this work was to develop and to evaluate methods to define relevant cross-sector quality indicators based on Austrian claims data, using myocardial infarction as tracer.

BACKGROUND: Trauma is the leading cause of death in patients <45 years living in high-resource settings. However, penetrating chest injuries are still relatively rare in Europe - with an upwards trend. These cases are of particular interest to emergency medical services (EMS) due to available invasive treatment options like chest tube placement or resuscitative thoracotomy. To date, there is no sufficient data from Austria regarding penetrating chest trauma in a metropolitan area, and no reliable source to base decisions regarding further skill proficiency training on. METHODS: For this retrospective observational study, we screened all trauma emergency responses of the Viennese EMS between 01/2009 and 12/2017 and included all those with a National Advisory Committee for Aeronautics (NACA) score ≥ IV (= potentially life-threatening). Data were derived from EMS mission documentations and hospital files, and for those cases with the injuries leading to cardiopulmonary resuscitation (CPR), we assessed the EMS cardiac arrest registry and consulted a forensic physician. RESULTS: We included 480 cases of penetrating chest injuries of NACA IV-VII (83% male, 64% > 30 years old, 74% stab wounds, 16% cuts, 8% gunshot wounds, 56% inflicted by another party, 26% self-inflicted, 18% unknown). In the study period, the incidence rose from 1.4/100,000 to 3.5/100,000 capita, and overall, about one case was treated per week. In the cases with especially severe injury patterns (= NACA V-VII, 43% of total), (tension-)pneumothorax was the most common injury (29%). The highest mortality was seen in injuries to pulmonary vessels (100%) or the heart (94%). Fifty-eight patients (12% of total) deceased, whereas in 15 cases, the forensic physician stated survival could theoretically have been possible. However, only five of these CPR patients received at least unilateral thoracostomy. Regarding all penetrating chest injuries, thoracostomy had only been performed in eight patients. CONCLUSIONS: Severe cases of penetrating chest trauma are rare in Vienna and happened about once a week between 2009 and 2017. Both incidence and case load increased over the years, and potentially life-saving invasive procedures were only reluctantly applied. Therefore, a structured educational and skill retention approach aimed at both paramedics and emergency physicians should be implemented. TRIAL REGISTRATION: Retrospective analysis without intervention.

BACKGROUND: In TAVI procedural stroke is one of the most feared complications and for this reason also extensively studied. But there is a lack of data concerning the impact of previous stroke on procedural stroke and on long-term survival. The aim of this registry-based cohort study is to evaluate the prevalence of previous stroke in TAVI patients and its impact on procedural stroke risk as well as long-term outcome. METHODS: We included all patients treated with TAVI between January 2007 and December 2020 and investigated concerning previous stroke in their medical history. Among 958 patients, 55 patients had previous stroke and were included in the present analysis. RESULTS: The salient finding of the present study is that previous stroke is significantly associated with higher all-cause mortality and has established itself as a predictor for poor outcome after TAVI. This is also observed after adjusting for confounders like EuroSCORE II (European system for cardiac operative risk evaluation) and AF (atrial fibrillation) as one of the main underlying diseases for cerebrovascular insult (CVI). However, previous stroke is not associated with higher rates of procedural CVI. CONCLUSION: A history of stroke is significantly associated with higher all-cause mortality and has established itself as a predictor for poor outcome after TAVI without higher rates of procedural stroke.

BACKGROUND: Although one-half of all public out-of-hospital cardiac arrests (OHCAs) occur outside private homes in residential neighborhoods, their characteristics and outcomes remain unexplored. OBJECTIVES: The authors assessed interventions before ambulance arrival and survival for public OHCA patients in residential neighborhoods. METHODS: Public OHCAs from Vienna (2018-2021) and Copenhagen (2016-2020) were designated residential neighborhoods or nonresidential areas. Interventions (cardiopulmonary resuscitation [CPR], automated external defibrillator [AED] attached, and defibrillation) and 30-day survival were compared using a generalized estimation equation model adjusted for age and time of day and presented as ORs. RESULTS: We included 1,052 and 654 public OHCAs from Vienna and Copenhagen, respectively, and 68% and 55% occurred in residential neighborhoods, respectively. The likelihood of CPR, defibrillation, and survival in residential neighborhoods vs nonresidential areas (reference) were as follows: CPR Vienna, 73% vs 78%, OR: 0.78 (95% CI: 0.57-1.06), CPR Copenhagen, 83% vs 90%, OR: 0.54 (95% CI: 0.34-0.88), and CPR combined, 76% vs 84%, OR: 0.70 (95% CI: 0.53-0.90); AED attached Vienna, 36% vs 44%, OR: 0.69 (95% CI: 0.53-0.90), AED attached Copenhagen, 21% vs 43%, OR: 0.33 (95% CI: 0.24-0.48), and AED attached combined, 31% vs 44%, OR: 0.53 (95% CI: 0.42-0.65); defibrillation Vienna, 14% vs 20%, OR: 0.61 (95% CI: 0.43-0.87), defibrillation Copenhagen, 16% vs 36%, OR: 0.35 (95% CI: 0.24-0.51), and defibrillation combined, 15% vs 27%, OR: 0.46 (95% CI: 0.36-0.61); and 30-day survival rate Vienna, 21% vs 26%, OR: 0.84 (95% CI: 0.58-1.20), 30-day survival rate Copenhagen, 33% vs 44%, OR: 0.65 (95% CI: 0.47-0.90), and 30-day survival rate combined, 25% vs 36%, OR: 0.73 (95% CI: 0.58-0.93). CONCLUSIONS: Two-thirds of public OHCAs occurred in residential neighborhoods with fewer resuscitative efforts before ambulance arrival and lower survival than in nonresidential areas. Targeted efforts to improve early CPR and defibrillation for public OHCA patients in residential neighborhoods are needed.

PURPOSE: Acute heart failure (AHF) represents a critical and life-threatening condition characterized by the sudden onset or exacerbation of symptoms, such as dyspnea and fluid retention, due to impaired cardiac function. Despite advances in the treatment of chronic heart failure (HF), the management of AHF remains challenging, with limited therapeutic options available. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as a promising drug class in AHF management. METHODS/RESULTS: The objective of this article was to conduct a comprehensive review of the existing literature in the domain of SGLT2 inhibitors and their relevance in the context of AHF. CONCLUSION: The existing evidence underscores the importance of SGLT2 inhibitors in enhancing decongestive therapy for AHF patients. Early initiation appears both practical and beneficial, leading to improved and sustained decongestion, a reduction in heart failure-related events, enhanced quality of life, and decreased mortality rates, all while maintaining a favorable safety profile. Consequently, it should be considered to initiate SGLT2 inhibitor treatment as early and as safely as possible to facilitate effective decongestion. However, careful patient selection and monitoring are essential when considering the use of these drugs in the management of AHF.
ABSTRACT
Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) improve cardiovascular outcomes in patients with type 2 diabetes mellitus (T2DM) and heart failure (HF). In consideration of emerging evidence that there are clinically relevant sex-related differences in the course of T2DM and subsequent cardiovascular outcomes, it is unknown if SGLT2i therapy is sex-independently utilized in daily clinical practice. Methods: Patients with T2DM and HF admitted to a tertiary academic center between January 2014 and April 2020 were identified through a search of electronic health records. Data on antidiabetic therapy were acquired at discharge and were screened for SGLT2i prescription. Results: Overall, 812 patients (median age 70 years, 29.7% female) were included in the present analysis. Only 17.3% of the study population received an SGLT2i. In comparison between sexes, females show lower rates of SGLT2i prescription (11.2% vs. 19.8%, p = 0.003), despite comparable patient characteristics. Furthermore, male HF patients showed a significantly higher probability of SGLT2i prescription with an adjusted odds ratio of 2.59 (95% confidence interval 1.29-5.19; p = 0.008). Females who did not receive an SGLT2i showed higher rates of chronic kidney disease (25.2% vs. 7.4%, p = 0.039) and greater levels of N-terminal pro b-type natriuretic peptide (NT-proBNP; 2092 vs. 825 pg/mL, p = 0.011) as compared to female SGLT2i recipients, which did not explain the observed sex-related disparities. Conclusion: SGLT2i are potentially underutilized in female patients with HF and T2DM, despite an overall increasing prescription trend during the observation period. Reasons for withholding therapy could not be objectified. The present data indicate a major need to increase awareness of guideline-directed therapy, especially in female HF patients.

First responders are an essential part of the chain (-mail) of survival as they bridge and reduce the time to first chest compressions and defibrillation substantially. However, in the peri-mission phase before and after being sent to a cardiac arrest, these first responders are in danger of being forgotten and taken for granted, and the potential psychological impact has to be remembered. We propose a standardized first responder support system (FRSS) that needs to ensure that first responders are valued and cared for in terms of psychological safety and continuing motivation. This multi-tiered program should involve tailored education and standardized debriefing, as well as actively seeking contact with the first responders after their missions to facilitate potentially needed professional psychological support.
ABSTRACT
BACKGROUND: Purinergic signaling receptor Y12 (P2Y12) inhibitors are a fundamental part of pharmacological therapy in acute coronary syndrome (ACS) for preventing recurrent ischemic events. Current guidelines support the use of prasugrel over ticagrelor-however, ticagrelor is widely used for preclinical loading during ACS due to its ease of administration. In this regard, it remains unknown whether the preclinical loading with P2Y12 inhibitors impacts decision-making for the long-term dual antiplatelet strategy, as well as cardiovascular outcomes, including re-percutaneous coronary intervention in real-world settings. METHODS: Within this population-based prospective observational study, all patients with ACS who received medical care via the Emergency Medical Service (EMS) in the city of Vienna between January 2018 and October 2020 were enrolled. Patients were stratified according to their P2Y12 inhibitor loading regimen. Subsequently, the association of P2Y12 inhibitor loading on long-term prescription at discharge and outcome was assessed. RESULTS: The entire study cohort consisted of 1176 individuals with ST-elevation myocardial infarction (STEMI), of whom 47.5% received prasugrel and 52.5% ticagrelor. The likelihood of adhering to the initial P2Y12 inhibitor strategy during the clinical stay was high for both ticagrelor (84%; OR: 10.00; p < 0.001) and prasugrel (77%; OR: 21.26; p < 0.001). During patient follow-up (median follow-up time three years), 84 (7.1%) patients died due to cardiovascular causes, and 82 (7.0%) patients required re-PCI. Notably, there was no difference in cardiovascular mortality (6.6% ticagrelor vs. 7.7% prasugrel) or re-PCI rates (6.6% ticagrelor vs. 7.3% prasugrel) addressing the P2Y12 inhibition strategy. CONCLUSION: We observed that, regardless of the initial antiplatelet inhibitor strategy, the in-hospital P2Y12 adherence was exceedingly high, and there was a minimal occurrence of switching to another P2Y12 inhibitor. Most importantly, no significant difference in cardiovascular death/re-PCI between ticagrelor and prasugrel-based preclinical loading has been observed. Consequently, the choice of high potent P2Y12 did not influence the cardiac outcome from a long-term perspective.
ABSTRACT
BACKGROUND: The highly ß1-selective beta-blocker Landiolol is known to facilitate efficient and safe rate control in non-compensatory tachycardia or dysrhythmia when administered continuously. However, efficacy and safety data of the also-available bolus formulation in critically ill patients are scarce. METHODS: We conducted a retrospective cross-sectional study on a real-life cohort of critical care patients, who had been treated with push-dose Landiolol due to sudden-onset non-compensatory supraventricular tachycardia. Continuous hemodynamic data had been acquired via invasive blood pressure monitoring. RESULTS: Thirty patients and 49 bolus applications were analyzed. Successful heart rate control was accomplished in 20 (41%) cases, rhythm control was achieved in 13 (27%) episodes, and 16 (33%) applications showed no effect. Overall, the heart rate was significantly lower (145 (130-150) vs. 105 (100-125) bpm, p < 0.001) in a 90 min post-application observational period in all subgroups. The median changes in blood pressure after the bolus application did not reach clinical significance. Compared with the ventilation settings before the bolus application, the respiratory settings including the required FiO2 after the bolus application did not differ significantly. No serious adverse events were seen. CONCLUSIONS: Push-dose Landiolol was safe and effective in critically ill ICU patients. No clinically relevant impact on blood pressure was noted.
