Mortality from cardiogenic shock remains high and early recognition and risk stratification are mandatory for optimal patient allocation and to guide treatment strategy. The CardShock and the Intra-Aortic Balloon Counterpulsation in Acute Myocardial Infarction Complicated by Cardiogenic Shock (IABP-SHOCK II) risk scores have shown good results in predicting short-term mortality in cardiogenic shock. However, to date, they have not been compared in a large cohort of ischaemic and non-ischaemic real-world cardiogenic shock patients. The Red-Shock is a multicentre cohort of non-selected cardiogenic shock patients. We calculated the CardShock and IABP-SHOCK II risk scores in each patient and assessed discrimination and calibration. Results: We included 696 patients. The main cause of cardiogenic shock was acute coronary syndrome, occurring in 62% of the patients. Compared with acute coronary syndrome patients, non-acute coronary syndrome patients were younger and had a lower proportion of risk factors but higher rates of renal insufficiency; intra-aortic balloon pump was also less frequently used (31% vs 56%). In contrast, non-acute coronary syndrome patients were more often treated with mechanical circulatory support devices (11% vs 3%, p=0.001 for both). Both risk scores were good predictors of in-hospital mortality in acute coronary syndrome patients and had similar areas under the receiver-operating characteristic curve (area under the curve: 0.742 for the CardShock vs 0.752 for IABP-SHOCK II, p=0.65). Their discrimination performance was only modest when applied to non-acute coronary syndrome patients (0.648 vs 0.619, respectively, p=0.31). Calibration was acceptable for both scores (Hosmer-Lemeshow p=0.22 for the CardShock and 0.68 for IABP-SHOCK II). In our cohort, both the CardShock and the IABP-SHOCK II risk scores were good predictors of in-hospital mortality in acute coronary syndrome-related cardiogenic shock., Depto. de Medicina, Fac. de Medicina, TRUE, pub

Aims International guidelines give recommendations for the management of comatose out-of-hospital cardiac arrest (OHCA) survivors. We aimed to investigate adherence to guidelines and disparities in the treatment of OHCA in hospitals in Europe. Methods and results A web-based, multi-institutional, multinational survey in Europe was conducted using an electronic platform with a predefined questionnaire developed by experts in post-resuscitation care. The survey was disseminated to all members of the societies via email, social media, websites, and newsletters in June 2021. Of 252 answers received, 237 responses from different units were included and 166 (70%) were from cardiac arrest centres. First-line vasopressor used was noradrenaline in 195 (83%) and the first-line inotrope was dobutamine in 148 (64%) of the responses. Echocardiography is available 24/7 in 204 (87%) institutions. Targeted temperature management was used in 160 (75%) institutions for adult comatose survivors of OHCA with an initial shockable rhythm. Invasive or external cooling methods with feedback were used in 72 cardiac arrest centres (44%) and 17 (24%) non-cardiac arrest centres (P < 0.0003). A target temperature between 32 and 34 degrees C was preferred by 46 centres (21%); a target between 34 and 36 degrees C by 103 centres (52%); and <37.5 degrees C by 35 (16%). Multimodal neuroprognostication was poorly implemented and a follow-up at 3 months after discharge was done in 71 (30%) institutions. Conclusion Post-resuscitation care is not well established and varies among centres in European hospitals. Cardiac arrest centres have a higher coherence with guidelines compared with respondents from non-cardiac arrest centres. The overall inconsistency in approaches and deviation from recommendations could be a focus for improvement.

Aims Quality of care (QoC) is a fundamental tenet of modern healthcare and has become an important assessment tool for healthcare authorities, stakeholders and the public. However, QoC is difficult to measure and quantify because it is a multifactorial and multidimensional concept. Comparison of clinical institutions can be challenging when QoC is estimated solely based on clinical outcomes. Thus, measuring quality through quality indicators (QIs) can provide a foundation for quality assessment and has become widely used in this context. QIs for the evaluation of QoC in acute myocardial infarction are now well-established, but no such indicators exist for the process from resuscitation of cardiac arrest and post-resuscitation care in Europe. Methods and results The Association of Acute Cardiovascular Care of the European Society Cardiology, the European Resuscitation Council, European Society of Intensive Care Medicine and the European Society for Emergency Medicine, have reflected on the measurement of QoC in cardiac arrest. A set of QIs have been proposed, with the scope to unify and evolve QoC for the management of cardiac arrest across Europe. Conclusion We present here the list of QIs (6 primary QIs and 12 secondary Qis), with descriptions of the methodology used, scientific justification and motives for the choice for each measure with the aim that this set of QIs will enable assessment of the quality of postout-of-hospital cardiac arrest management across Europe., Aims Quality of care (QoC) is a fundamental tenet of modern healthcare and has become an important assessment tool for healthcare authorities, stakeholders and the public.

The use of mechanical circulatory support using percutaneous ventricular assist devices (pVAD) has increased rapidly during the last decade without substantial new evidence for their effect on outcome. In addition, many gaps in knowledge still exist such as timing and duration of support, haemodynamic monitoring, management of complications, concomitant medical therapy, and weaning protocols. This clinical consensus statement summarizes the consensus of an expert panel of the Association for Acute CardioVascular Care, European Society of Intensive Care Medicine, European Extracorporeal Life Support Organization, and European Association for Cardio-Thoracic Surgery. It provides practical advice regarding the management of patients managed with pVAD in the intensive care unit based on existing evidence and consensus on best current practice., The use of mechanical circulatory support using percutaneous ventricular assist devices (pVAD) has increased rapidly during the last decade without substantial new evidence for their effect on outcome.

Introduction: Myocardial infarction with ST-segment elevation (STEMI) is the coronary artery disease associated with the highest risk of morbimortality; however, this risk is heterogeneous, usually being evaluated by clinical scores. Risk assessment is a key factor in personalized clinical management of patients with this disease. Aim: The aim of this study was to assess whether some new cardiac biomarkers considered alone, combined in a multibiomarker model or in association with clinical variables, improve the short- and long-term risk stratification of STEMI patients. Materials and Methods: This was a retrospective observational study of 253 patients with STEMI. Blood samples were obtained before or during the angiography. The assessed biomarkers were C-terminal fragment of insulin-like growth factor binding protein-4 (CT-IGFBP4), high sensitive cardiac troponin T (hs-cTnT), N-terminal fragment of probrain natriuretic peptide (NT-proBNP), and growth differentiation factor 15 (GDF-15); they reflect different cardiovascular (CV) physiopathological pathways and underlying pathologies. We registered in-hospital and follow-up mortalities and their causes (cardiovascular and all-cause) and major adverse cardiac events (MACE) during a two year follow-up. Discrimination, survival analysis, model calibration, and reclassification of the biomarkers were comprehensively evaluated. Results and Discussion: In total, 55 patients (21.7%) died, 33 in-hospital and 22 during the follow-up, most of them (69.1%) from CV causes; 37 MACE occurred during follow-up. Biomarkers showed good prognostic ability to predict mortality, alone and combined with the multibiomarker model. A predictive clinical model based on age, Killip-Kimball class, estimated glomerular filtration rate (eGFR), and heart rate was derived by multivariate analysis. GDF-15 and NT-proBNP significantly improved risk assessment of the clinical model, as shown by discrimination, calibration, and reclassification of all

After experiencing an acute coronary syndrome (ACS), patients are at a high risk of suffering from recurrent ischaemic cardiovascular events, especially in the very early phase. Low density lipoprotein-cholesterol (LDL-C) is causally involved in atherosclerosis and a clear, monotonic relationship between pharmacologic LDL-C lowering and a reduction in cardiovascular events post-ACS has been shown, a concept termed 'the lower, the better'. Current ESC guidelines suggest an LDL-C guided, step-wise initiation and escalation of lipid-lowering therapy (LLT). Observational studies consistently show low rates of guideline-recommended LLT adaptions and concomitant low rates of LDL-C target goal achievement, leaving patients at residual risk, especially in the vulnerable post-ACS phase. In addition to the well-established 'the lower, the better' approach, a 'strike early and strike strong' approach in the early post-ACS phase with upfront initiation of a combined lipid-lowering approach using high-intensity statins and ezetimibe seems reasonable. We discuss the rationale, clinical trial evidence and experience for such an approach and highlight existing knowledge gaps. In addition, the concept of acute initiation of PCSK9 inhibition in the early phase is reviewed. Ultimately, we focus on hurdles and solutions to provide high-quality, evidence-based follow-up care in post-ACS patients.

Aims Cardiogenic shock (CS) is a life-threatening condition burdened by mortality in up to 50% of cases. Few recommendations exist with intermediate-low level of evidence on CS management and no data on adherence across centres exist. We performed a survey to frame CS management at multinational level. Methods and results An international cross-sectional survey was created and approved by European Society of Cardiology-Acute Cardiovascular Care Association board. A total of 337 responses from 60 countries were obtained. Data were assessed by the hospital level of care of the participants. The most common cause of CS was AMI (AMI-CS-79.9%) with significant difference according to hospital levels (P = 0.001), followed by acutely decompensated heart failure (HF) (13.4%), myocarditis (3.5%), and de novo HF (1.75%). In 37.8%, percutaneous coronary intervention (PCI) is performed to all CS-patients as a standard approach, whereas 42.1% used PCI if electrocardiogram suggestive of ischaemia and 20.1% only if Universal definition of myocardial infarction criteria are fulfilled. Management (catecholamine titration and mechanical circulatory support escalation) is driven by mean arterial pressure (87.1%), echocardiography (84.4%), and lactate levels (83.4%). Combination of vasopressor and inotrope is chosen with the same frequency (37.7%) than inotrope alone as first-line pharmacological therapy (differences amongst hospital levels; P > 0.5). Noradrenaline is first-line vasopressor (89.9%) followed by dopamine (8.5%), whereas dobutamine is confirmed as the first-line inotrope (65.9%). Conclusion Cardiogenic shock management is heterogenous and often not adherent to current recommendations. Quality improvement on an international level with evidence-based quality indicators should be developed to standardize diagnostic and therapeutic pathways.

Aims: Optimal outcome after cardiogenic shock (CS) depends on a coordinated healing response in which both debris removal and extracellular matrix tissue repair play a crucial role. Excessive inflammation can perpetuate a vicious circle, positioning leucocytes as central protagonists and potential therapeutic targets. High levels of circulating Triggering Receptor Expressed on Myeloid cells-1 (TREM-1), were associated with death in acute myocardial infarction confirming excessive inflammation as determinant of bad outcome. The present study aims to describe the association of soluble TREM-1 with 90-day mortality and with various organ injuries in patients with CS. Methods and results: This is a post-hoc study of CardShock, a prospective, multicenter study assessing the clinical presentation and management in patients with CS. At the time of this study, 87 patients had available plasma samples at either baseline, and/or 48 h and/or 96–120 h for soluble TREM-1 (sTREM-1) measurements. Plasma concentration of sTREM-1 was higher in 90-day non-survivors than survivors at baseline [median: 1392 IQR: (724–2128) vs. 621 (525–1233) pg/mL, p = 0.008), 48 h (p = 0.019) and 96–120 h (p = 0.029). The highest tertile of sTREM-1 at baseline (threshold: 1347 pg/mL) was associated with 90-day mortality with an unadjusted HR 3.08 CI 95% (1.48–6.42). sTREM-1 at baseline was not associated to hemodynamic parameters (heart rate, blood pressure, use of vasopressors or inotropes) but rather with organ injury markers: renal (estimated glomerular filtration rate, p = 0.0002), endothelial (bio-adrenomedullin, p = 0.018), myocardial (Suppression of Tumourigenicity 2, p = 0.002) or hepatic (bilirubin, p = 0.008). Conclusion: In CS patients TREM-1 pathway is highly activated and gives an early prediction of vital organ injuries and outcome. Graphic abstract: [Figure not available: see fulltext.].

Acute kidney injury (AKI) is a frequent form of organ injury in cardiogenic shock. However, data on AKI markers such as plasma proenkephalin (P-PENK) and neutrophil gelatinase-associated lipocalin (P-NGAL) in cardiogenic shock populations are lacking. The objective of this study was to assess the ability of P-PENK and P-NGAL to predict acute kidney injury and mortality in cardiogenic shock. P-PENK and P-NGAL were measured at different time points between baseline and 48 h in 154 patients from the prospective CardShock study. The outcomes assessed were AKI defined by an increase in creatinine within 48 h and all-cause 90-day mortality. Mean age was 66 years and 26% were women. Baseline levels of P-PENK and P-NGAL (median [interquartile range]) were 99 (71-150) pmol/mL and 138 (84-214) ng/mL. P-PENK > 84.8 pmol/mL and P-NGAL > 104 ng/mL at baseline were identified as optimal cut-offs for AKI prediction and independently associated with AKI (adjusted HRs 2.2 [95% CI 1.1-4.4, p = 0.03] and 2.8 [95% CI 1.2-6.5, p = 0.01], respectively). P-PENK and P-NGAL levels at baseline were also associated with 90-day mortality. For patients with oliguria < 0.5 mL/kg/h for > 6 h before study enrollment, 90-day mortality differed significantly between patients with low and high P-PENK/P-NGAL at baseline (5% vs. 68%, p < 0.001). However, the biomarkers provided best discrimination for mortality when measured at 24 h. Identified cut-offs of P-PENK > 105.7 pmol/L and P-NGAL > 151 ng/mL had unadjusted hazard ratios of 5.6 (95% CI 3.1-10.7, p < 0.001) and 5.2 (95% CI 2.8-9.8, p < 0.001) for 90-day mortality. The association remained significant despite adjustments with AKI and two risk scores for mortality in cardiogenic shock. High levels of P-PENK and P-NGAL at baseline were independently associated with AKI in cardiogenic shock patients. Furthermore, oliguria before study inclusion was associated with worse outcomes only if combined with high baseline levels of P-PENK or P-NGAL. High le

Cardiogenic shock (CS) is a life-threatening emergency. New biomarkers are needed in order to detect patients at greater risk of adverse outcome. Our aim was to assess the characteristics of miR-21-5p, miR-122-5p, and miR-320a-3p in CS and evaluate the value of their expression levels in risk prediction. Circulating levels of miR-21-5p, miR-122-5p, and miR-320a-3p were measured from serial plasma samples of 179 patients during the first 5-10 days after detection of CS, derived from the CardShock study. Acute coronary syndrome was the most common cause (80%) of CS. Baseline (0 h) levels of miR-21-5p, miR-122-5p, and miR-320a-3p were all significantly elevated in nonsurvivors compared to survivors (p < 0.05 for all). Above median levels at 0h of each miRNA were each significantly associated with higher lactate and alanine aminotransferase levels and decreased glomerular filtration rates. After adjusting the multivariate regression analysis with established CS risk factors, miR-21-5p and miR-320a-3p levels above median at 0 h were independently associated with 90-day all-cause mortality (adjusted hazard ratio 1.8 (95% confidence interval 1.1-3.0), p = 0.018; adjusted hazard ratio 1.9 (95% confidence interval 1.2-3.2), p = 0.009, respectively). In conclusion, circulating plasma levels of miR-21-5p, miR-122-5p, and miR-320a-3p at baseline were all elevated in nonsurvivors of CS and associated with markers of hypoperfusion. Above median levels of miR-21-5p and miR-320a-3p at baseline appear to independently predict 90-day all-cause mortality. This indicates the potential of miRNAs as biomarkers for risk assessment in cardiogenic shock.

Current electrocardiographic algorithms lack sensitivity to diagnose acute myocardial infarction () in the presence of left bundle branch block. A multicenter retrospective cohort study including consecutive patients with suspected and left bundle branch block, referred for primary percutaneous coronary intervention between 2009 and 2018. Pre-2015 patients formed the derivation cohort (n=163, 61 with ); patients between 2015 and 2018 formed the validation cohort (n=107, 40 with ). A control group of patients without suspected was also studied (n=214). Different electrocardiographic criteria were tested. A total of 484 patients were studied. A new electrocardiographic algorithm ( algorithm) was derived and validated. The algorithm is positive in the presence of deviation ≥1 mm (0.1 mV) concordant with polarity, in any lead, or deviation ≥1 mm (0.1 mV) discordant with the , in leads with max (R $s ) voltage (the voltage of the largest deflection of the , ie, R or S wave) ≤6 mm (0.6 mV). In both the derivation and the validation cohort, the algorithm achieved the highest sensitivity (93%-95%), negative predictive value (96%-97%), efficiency (91%-94%) and area under the receiver operating characteristic curve (0.92-0.93), significantly higher than previous electrocardiographic rules (P <0.01); the specificity was good in both groups (89%-94%) as well as the control group (90%). In patients with left bundle branch block referred for , the algorithm was specific and highly sensitive for the diagnosis of , leading to a diagnostic accuracy comparable to that obtained by in patients without left bundle branch block.

BACKGROUND: Although the lungs are potentially highly susceptible to post-cardiac arrest syndrome injury, the issue of acute respiratory failure after out-of-hospital cardiac arrest has not been investigated. The objectives of this analysis were to determine the prevalence of acute respiratory failure after out-of-hospital cardiac arrest, its association with post-cardiac arrest syndrome inflammatory response and to clarify its importance for early mortality.METHODS: The Post-Cardiac Arrest Syndrome (PCAS) pilot study was a prospective, observational, six-centre project (Poland 2, Denmark 1, Spain 1, Italy 1, UK 1), studying patients resuscitated after out-of-hospital cardiac arrest of cardiac origin. Primary outcomes were: (a) the profile of organ failure within the first 72 hours after out-of-hospital cardiac arrest; (b) in-hospital and short-term mortality, up to 30 days of follow-up. Respiratory failure was defined using a modified version of the Berlin acute respiratory distress syndrome definition. Inflammatory response was defined using leukocytes (white blood cells), platelet count and C-reactive protein concentration. All parameters were assessed every 24 hours, from admission until 72 hours of stay.RESULTS: Overall, 148 patients (age 62.9±15.27 years; 27.7% women) were included. Acute respiratory failure was noted in between 50 (33.8%) and 75 (50.7%) patients over the first 72 hours. In-hospital and short-term mortality was 68 (46.9%) and 72 (48.6%), respectively. Inflammation was significantly associated with the risk of acute respiratory failure, with the highest cumulative odds ratio of 748 at 72 hours (C-reactive protein 1.035 (1.001-1.070); 0.043, white blood cells 1.086 (1.039-1.136); 0.001, platelets 1.004 (1.001-1.007); <0.005). Early acute respiratory failure was related to in-hospital mortality (3.172, 95% confidence interval 1.496-6.725; 0.002) and to short-term mortality (3.335 (1.815-6.129); 0.0001).CONCLUSIONS: An i

Aims: Urgent revascularization is the mainstay of treatment in acute coronary syndrome (ACS) related cardiogenic shock (CS). The aim was to investigate the association of angiographic results with 90-day mortality. Procedural complications of percutaneous coronary intervention (PCI) were also examined. Methods and results: This CardShock (NCT01374867) substudy included 158 patients with ACS aetiology and data on coronary angiography and complications during PCI procedure. Survival analysis was conducted with Kaplan–Meier curves and Cox regression analysis. Median age was 67 ± 11 years, and 77% were men. During 90-day follow-up, 66 (42%) patients died. Patients with one-vessel disease (n = 49) had lower mortality than patients with two-vessel (n = 59) or three-vessel (n = 50) disease (25% vs. 48% vs. 52%, P = 0.011). Successful revascularization [Thrombolysis in Myocardial Infarction (TIMI) Flow 3 post-PCI) was achieved more often in survivors than non-survivors (81% vs. 60%, P = 0.019). The median symptom-to-balloon time was 340 (196–660) minutes, with no difference between survivors and non-survivors. In multivariable mortality analysis, multivessel disease (HR 2.59, CI95% 1.29–5.18) and TIMI flow <3 post-PCI (HR 2.41, CI95% 1.4–4.15) were associated with 90-day mortality. Procedural PCI complications were recorded in 51 (35%) patients, arrhythmic complications being the most common (n = 32, 63%). The incidence of complications was similar between survivors and non-survivors (31% vs. 42%, P = 0.21). Conclusions: Multivessel disease is associated with worse survival in ACS-related CS. In patients undergoing PCI, arrhythmic complications were common, but not associated with excess mortality. Successful revascularization of the IRA had positive effect on outcome despite delay from symptom onset.

Background: Cardiogenic shock (CS) is the most life-threatening manifestation of acute heart failure. Its complexity and high in-hospital mortality may justify the need for invasive monitoring with a pulmonary artery catheter (PAC). Methods: Patients with CS included in the CardShock Study, an observational, prospective, multicenter, European registry, were analyzed, aiming to describe the real-world use of PAC, evaluate its impact on 30-day mortality, and the ability of different hemodynamic parameters to predict outcomes. Results: Pulmonary artery catheter was used in 82 (37.4%) of the 219 patients. Cardiogenic shock patients who managed with a PAC received more frequently treatment with inotropes and vasopressors, mechanical ventilation, renal replacement therapy, and mechanical assist devices (P <.01). Overall 30-day mortality was 36.5%. Pulmonary artery catheter use did not affect mortality even after propensity score matching analysis (hazard ratio = 1.17 [0.59-2.32], P =.66). Cardiac index, cardiac power index (CPI), and stroke volume index (SVI) showed the highest areas under the curve for 30-day mortality (ranging from 0.752-0.803) and allowed for a significant net reclassification improvement of 0.467 (0.083-1.180), 0.700 (0.185-1.282), 0.683 (0.168-1.141), respectively, when added to the CardShock risk score. Conclusions: In our contemporary cohort of CS, over one-third of patients were managed with a PAC. Pulmonary artery catheter use was associated with a more aggressive treatment strategy. Nevertheless, PAC use was not associated with 30-day mortality. Cardiac index, CPI, and SVI were the strongest 30-day mortality predictors on top of the previously validated CardShock risk score.

INTRODUCTION: Cardiogenic shock complicating acute myocardial infarction has a very high mortality. Our present study focuses on serial measurement of lactate during admission due to cardiogenic shock and the prognostic effect of lactate and a relative change in lactate in patients after admission and the institution of intensive care treatment.METHODS AND RESULTS: This is a secondary analysis of the CardShock study. Data on lactate at baseline were available on 217 of 219 patients.In the study population, the median baseline lactate was 2.8 mmol/L (min-max range, 0.5-23.1 mmol/L).At admission, lactate was predictive of 30-day mortality with an adjusted Hazard ratio (HR) of 1.20 mmol/L (95% confidence interval, CI 1.14-1.27). Within the first 24 h of admission, baseline lactate remained predictive of 30-day mortality. Lactate at 6 h had a HR of 1.14 (95% CI 1.06-1.24) and corresponding values at 12 and 24 h had a HR of 1.10 (1.04-1.17), and of HR 1.19 (95% CI 1.07-1.32), respectively. A 50% reduction in lactate within 6 h resulted in a HR of 0.82 (95% CI 0.72-0.94). Corresponding hazard ratios at 12 and 24 h, were 0.87 (95% CI 0.76-0.98) and 0.74 (95% CI 0.60-0.91), respectively.CONCLUSION: The main findings of the present study are that baseline lactate is a powerful predictor of 30-day mortality, lactate at 6, 12, and 24 h after admission are predictors of 30-day mortality, and a relative change in lactate is a significant predictor of survival within the first 24 h after instituting intensive care treatment adding information beyond the information from baseline values.

Aims: Urgent revascularization is the mainstay of treatment in acute coronary syndrome (ACS) related cardiogenic shock (CS). The aim was to investigate the association of angiographic results with 90-day mortality. Procedural complications of percutaneous coronary intervention (PCI) were also examined. Methods and results: This CardShock (NCT01374867) substudy included 158 patients with ACS aetiology and data on coronary angiography and complications during PCI procedure. Survival analysis was conducted with Kaplan–Meier curves and Cox regression analysis. Median age was 67 ± 11 years, and 77% were men. During 90-day follow-up, 66 (42%) patients died. Patients with one-vessel disease (n = 49) had lower mortality than patients with two-vessel (n = 59) or three-vessel (n = 50) disease (25% vs. 48% vs. 52%, P = 0.011). Successful revascularization [Thrombolysis in Myocardial Infarction (TIMI) Flow 3 post-PCI) was achieved more often in survivors than non-survivors (81% vs. 60%, P = 0.019). The median symptom-to-balloon time was 340 (196–660) minutes, with no difference between survivors and non-survivors. In multivariable mortality analysis, multivessel disease (HR 2.59, CI95% 1.29–5.18) and TIMI flow <3 post-PCI (HR 2.41, CI95% 1.4–4.15) were associated with 90-day mortality. Procedural PCI complications were recorded in 51 (35%) patients, arrhythmic complications being the most common (n = 32, 63%). The incidence of complications was similar between survivors and non-survivors (31% vs. 42%, P = 0.21). Conclusions: Multivessel disease is associated with worse survival in ACS-related CS. In patients undergoing PCI, arrhythmic complications were common, but not associated with excess mortality. Successful revascularization of the IRA had positive effect on outcome despite delay from symptom onset.

Importance: Short-term infusions of single vasodilators, usually given in a fixed dose, have not improved outcomes in patients with acute heart failure (AHF). Objective: To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation using individualized up-titrated doses of established vasodilators in patients with AHF. Design, Setting, and Participants: Randomized, open-label blinded-end-point trial enrolling 788 patients hospitalized for AHF with dyspnea, increased plasma concentrations of natriuretic peptides, systolic blood pressure of at least 100 mm Hg, and plan for treatment in a general ward in 10 tertiary and secondary hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain. Enrollment began in December 2007 and follow-up was completed in February 2019. Interventions: Patients were randomized 1:1 to a strategy of early intensive and sustained vasodilation throughout the hospitalization (n = 386) or usual care (n = 402). Early intensive and sustained vasodilation was a comprehensive pragmatic approach of maximal and sustained vasodilation combining individualized doses of sublingual and transdermal nitrates, low-dose oral hydralazine for 48 hours, and rapid up-titration of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, or sacubitril-valsartan. Main Outcomes and Measures: The primary end point was a composite of all-cause mortality or rehospitalization for AHF at 180 days. Results: Among 788 patients randomized, 781 (99.1%; median age, 78 years; 36.9% women) completed the trial and were eligible for primary end point analysis. Follow-up at 180 days was completed for 779 patients (99.7%). The primary end point, a composite of all-cause mortality or rehospitalization for AHF at 180 days, occurred in 117 patients (30.6%) in the intervention group (including 55 deaths [14.4%]) and in 111 patients (27.8%) in the usual care group (including 61 deaths [15.3%]) (absolute difference for the primary end

BACKGROUND: Altered mental status is among the signs of hypoperfusion in cardiogenic shock, the most severe form of acute heart failure. The aim of this study was to investigate the prevalence of altered mental status, to identify factors associating with it, and to assess the prognostic significance of altered mental status in cardiogenic shock.METHODS: Mental status was assessed at presentation of shock in 215 adult cardiogenic shock patients in a multinational, prospective, observational study. Clinical picture, biochemical variables, and short-term mortality were compared between patients presenting with altered and normal mental status.RESULTS: Altered mental status was detected in 147 (68%) patients, whereas 68 (32%) patients had normal mental status. Patients with altered mental status were older (68 vs. 64 years, p=0.04) and more likely to have an acute coronary syndrome than those with normal mental status (85% vs. 74%, p=0.04). Altered mental status was associated with lower systolic blood pressure (76 vs. 80 mmHg, p=0.03) and lower arterial pH (7.27 vs. 7.35, p<0.001) as well as higher levels of blood lactate (3.4 vs. 2.3 mmol/l, p<0.001) and blood glucose (11.4 vs. 9.0 mmol/l, p=0.01). Low arterial pH (adjusted odds ratio 1.6 (1.1-2.2), p=0.02) was the only factor independently associated with altered mental status. Ninety-day mortality was significantly higher (51% vs. 22%, p<0.001) among patients with altered mental status.CONCLUSIONS: Altered mental status is a common clinical sign of systemic hypoperfusion in cardiogenic shock and is associated with poor outcome. It is also associated with several biochemical findings that reflect inadequate tissue perfusion, of which low arterial pH is independently associated with altered mental status.

Background: The most common aetiology of cardiogenic shock (CS) is acute coronary syndrome (ACS), but even up to 20%–50% of CS is caused by other disorders. ST-segment deviations in the electrocardiogram (ECG) have been investigated in patients with ACS-related CS, but not in those with other CS aetiologies. We set out to explore the prevalence of different ST-segment patterns and their associations with the CS aetiology, clinical findings and 90-day mortality. Methods: We analysed the baseline ECG of 196 patients who were included in a multinational prospective study of CS. The patients were divided into 3 groups: (a) ST-segment elevation (STE). (b) ST-segment depression (STDEP). (c) No ST-segment deviation or ST-segment impossible to analyse (NSTD). A subgroup analysis of the ACS patients was conducted. Results: ST-segment deviations were present in 80% of the patients: 52% had STE and 29% had STDEP. STE was associated with the ACS aetiology, but one-fourth of the STDEP patients had aetiology other than ACS. The overall 90-day mortality was 41%: in STE 47%, STDEP 36% and NSTD 33%. In the multivariate mortality analysis, only STE predicted mortality (HR 1.74, CI 95 1.07–2.84). In the ACS subgroup, the patients were equally effectively revascularized, and no differences in the survival were noted between the study groups. Conclusion: ST-segment elevation is associated with the ACS aetiology and high mortality in the unselected CS population. If STE is not present, other aetiologies must be considered. When effectively revascularized, the prognosis is similar regardless of the ST-segment pattern in ACS-related CS.

[Abstract] This paper provides a practical clinical application of guideline recommendations relating to the inpatient monitoring of patients with acute heart failure, through the evaluation of various clinical, biomarker, imaging, invasive and non‐invasive approaches. Comprehensive inpatient monitoring is crucial to the optimal management of acute heart failure patients. The European Society of Cardiology heart failure guidelines provide recommendations for the inpatient monitoring of acute heart failure, but the level of evidence underpinning most recommendations is limited. Many tools are available for the in‐hospital monitoring of patients with acute heart failure, and each plays a role at various points throughout the patient's treatment course, including the emergency department, intensive care or coronary care unit, and the general ward. Clinical judgment is the preeminent factor guiding application of inpatient monitoring tools, as the various techniques have different patient population targets. When applied appropriately, these techniques enable decision making. However, there is limited evidence demonstrating that implementation of these tools improves patient outcome. Research priorities are identified to address these gaps in evidence. Future research initiatives should aim to identify the optimal in‐hospital monitoring strategies that decrease morbidity and prolong survival in patients with acute heart failure.

Background The clinical CardShock risk score, including baseline lactate levels, was recently shown to facilitate risk stratification in patients with cardiogenic shock (CS). As based on baseline parameters, however, it may not reflect the change in mortality risk in response to initial therapies. Adrenomedullin is a prognostic biomarker in several cardiovascular diseases and was recently shown to associate with hemodynamic instability in patients with septic shock. The aim of our study was to evaluate the prognostic value and association with hemodynamic parameters of bioactive adrenomedullin (bio-ADM) in patients with CS. Methods CardShock was a prospective, observational, European multinational cohort study of CS. In this sub-analysis, serial plasma bio-ADM and arterial blood lactate measurements were collected from 178 patients during the first 10 days after detection of CS. Results Both bio-ADM and lactate were higher in 90-day non-survivors compared to survivors at all time points (P < 0.05 for all). Lactate showed good prognostic value during the initial 24 h (AUC 0.78 at admission and 0.76 at 24 h). Subsequently, lactate returned normal (≤2 mmol/L) in most patients regardless of later outcome with lower prognostic value. By contrast, bio-ADM showed increasing prognostic value from 48 h and beyond (AUC 0.71 at 48 h and 0.80 at 5–10 days). Serial measurements of either bio-ADM or lactate were independent of and provided added value to CardShock risk score (P < 0.001 for both). Ninety-day mortality was more than double higher in patients with high levels of bio-ADM (>55.7 pg/mL) at 48 h compared to those with low bio-ADM levels (49.1 vs. 22.6%, P = 0.001). High levels of bio-ADM were associated with impaired cardiac index, mean arterial pressure, central venous pressure, and systolic pulmonary artery pressure during the study period. Furthermore, high levels of bio-ADM at 48 to 96 h were related to persistently impaired cardiac and end-organ function.

BACKGROUND: Critically ill patients often present with hyperglycemia, regardless of previous history of diabetes mellitus (DM). Hyperglycemia has been associated with adverse outcome in acute myocardial infarction and acute heart failure. We investigated the association of admission blood glucose level with the clinical picture and short-term mortality in cardiogenic shock (CS).METHODS: Consecutively enrolled CS patients were divided into five categories according to plasma glucose level at the time of enrolment: hypoglycemia (glucose <4.0mmol/L), normoglycemia (4.0-7.9mmol/L), mild (8.0-11.9mmol/L), moderate (12.0-15.9mmol/L), and severe (≥16.0mmol/L) hyperglycemia. Clinical presentation, biochemistry, and short-term mortality were compared between the groups.RESULTS: Plasma glucose level of 211 CS patients was recorded. Glucose levels were distributed equally between normoglycemia (26% of patients), mild (27%), moderate (19%) and severe (25%) hyperglycemia, while hypoglycemia (2%) was rare. Severe hyperglycemia was associated with higher blood leukocyte count (17.3 (5.8) E9/L), higher lactate level (4.4 (3.3-8.4) mmol/L) and lower arterial pH (7.23 (0.14)) compared with normoglycemia or mild to moderate hyperglycemia (p<0.001 for all). In-hospital mortality was highest among hypoglycemic (60%) and severely hyperglycemic (56%) patients, compared with 22% in normoglycemic group (p<0.01). Severe hyperglycemia was an independent predictor of in-hospital mortality (OR 3.7, 95% CI 1.19-11.7, p=0.02), when adjusted for age, gender, LVEF, lactate, and DM.CONCLUSIONS: Admission blood glucose level has prognostic significance in CS. Mortality is highest among patients with severe hyperglycemia or hypoglycemia. Severe hyperglycemia is independently associated with high in-hospital mortality in CS. It is also associated with biomarkers of systemic hypoperfusion and stress response.

BACKGROUND: Despite scarce data, invasive mechanical ventilation (MV) is widely recommended over non-invasive ventilation (NIV) for ventilatory support in cardiogenic shock (CS). We assessed the real-life use of different ventilation strategies in CS and their influence on outcome focusing on the use of NIV and MV.METHODS: 219 CS patients were categorized by the maximum intensity of ventilatory support they needed during the first 24h into MV (n=137; 63%) , NIV (n=26; 12%), and supplementary oxygen (n=56; 26%) groups. We compared the clinical characteristics and 90-day outcome between the MV and the NIV groups.RESULTS: Mean age was 67years, 74% were men. The MV and NIV groups did not differ in age, medical history, etiology of CS, PaO2/FiO2 ratio, baseline hemodynamics or LVEF. MV patients predominantly presented with hypoperfusion, with more severe metabolic acidosis, higher lactate levels and greater need for vasoactive drugs, whereas NIV patients tended to be more often congestive. 90-day outcome was significantly worse in the MV group (50% vs. 27%), but after propensity score adjustment, mortality was equal in both groups. Confusion, prior CABG, ACS etiology, higher lactate level, and lower baseline PaO2 were independent predictors of mortality, whereas ventilation strategy did not have any influence on outcome.CONCLUSIONS: Although MV is generally recommended mode of ventilatory support in CS, a fair number of patients were successfully treated with NIV. Moreover, ventilation strategy was not associated with outcome. Thus, NIV seems a safe option for properly chosen CS patients.

AIMS: The aim of this study was to investigate the clinical picture and outcome of cardiogenic shock and to develop a risk prediction score for short-term mortality.METHODS AND RESULTS: The CardShock study was a multicentre, prospective, observational study conducted between 2010 and 2012. Patients with either acute coronary syndrome (ACS) or non-ACS aetiologies were enrolled within 6 h from detection of cardiogenic shock defined as severe hypotension with clinical signs of hypoperfusion and/or serum lactate >2 mmol/L despite fluid resuscitation (n = 219, mean age 67, 74% men). Data on clinical presentation, management, and biochemical variables were compared between different aetiologies of shock. Systolic blood pressure was on average 78 mmHg (standard deviation 14 mmHg) and mean arterial pressure 57 (11) mmHg. The most common cause (81%) was ACS (68% ST-elevation myocardial infarction and 8% mechanical complications); 94% underwent coronary angiography, of which 89% PCI. Main non-ACS aetiologies were severe chronic heart failure and valvular causes. In-hospital mortality was 37% (n = 80). ACS aetiology, age, previous myocardial infarction, prior coronary artery bypass, confusion, low LVEF, and blood lactate levels were independently associated with increased mortality. The CardShock risk Score including these variables and estimated glomerular filtration rate predicted in-hospital mortality well (area under the curve 0.85).CONCLUSION: Although most commonly due to ACS, other causes account for one-fifth of cases with shock. ACS is independently associated with in-hospital mortality. The CardShock risk Score, consisting of seven common variables, easily stratifies risk of short-term mortality. It might facilitate early decision-making in intensive care or guide patient selection in clinical trials.TRIAL REGISTRATION: NCT01374867.
