Impact of intra-aortic balloon pump on short-term clinical outcomes in ST-elevation myocardial infarction complicated by cardiogenic shock: A "real life" single center experience.

OBJECTIVE: To analyze the use and impact of the intra-aortic balloon pump (IABP) upon the 30-day mortality rate and short-term clinical outcome of non-selected patients with ST-elevation acute myocardial infarction (acute STEMI) complicated by cardiogenic shock (CS). DESIGN: A single-center retrospective case-control study was carried out. SETTING: Coronary Care Unit. PATIENTS: Data were collected from 825 consecutive patients with acute STEMI admitted to a Coronary Care Unit from January 2009 to August 2015. Seventy-three patients with CS upon admission subjected to emergency percutaneous coronary intervention (PCI) were finally included in the analysis and were stratified according to IABP use (44 patients receiving IABP). VARIABLES: Cardiovascular history, hemodynamic situation upon admission, angiographic and procedural characteristics, and variables derived from admission to the Coronary Care Unit. RESULTS: Cumulative 30-day mortality was similar in the patients subjected to IABP and in those who received conventional medical therapy only (29.5% and 27.6%, respectively; HR with IABP 1.10, 95% CI 0.38-3.11; p=0.85). Similarly, no significant differences were found in terms of the short-term clinical outcome between the groups: time on mechanical ventilation, days to hemodynamic stabilization, vasoactive drug requirements and stay in the Coronary Care Unit. Poorer renal function (HR 3.9, 95% CI 1.4-10.6; p=0.008), known peripheral artery disease (HR 3.3, 95% CI 1.2-9.1; p=0.019) and a history of diabetes mellitus (HR 3.2, 95% CI 1.2-8.1; p=0.018) were the only variables independently associated to increased 30-day mortality. CONCLUSION: In our "real life" experience, IABP does not modify 30-day mortality or the short-term clinical outcome in patients presenting STEMI complicated with CS and subjected to emergency percutaneous coronary revascularization.

Hemodynamic monitoring and echocardiographic evaluation in cardiogenic shock.

Cardiogenic shock (CS) is characterized by the presence of a state of tissue hypoperfusion secondary to ventricular dysfunction. Hemodynamic monitoring allows us to obtain information about cardiovascular pathophysiology that will help us make the diagnosis and guide therapy in CS situations. The most used monitoring system in CS is the pulmonary artery catheter since it provides key hemodynamic variables in CS, such as cardiac output, pulmonary artery pressure, and pulmonary artery occlusion pressure. On the other hand, echocardiography makes it possible to obtain, at the bedside, anatomical and hemodynamic data that complement the information obtained through continuous monitoring devices. CS monitoring can be considered multimodal and integrative by including hemodynamic, metabolic, and echocardiographic parameters that allow describing the characteristics of CS and guiding therapeutic interventions during hemodynamic resuscitation.

Clinical profile, management and outcomes of patients with cardiogenic shock undergoing transfer between centers in Spain.

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze the clinical profile, management, and prognosis of ST segment elevation myocardial infarction-related cardiogenic shock (STEMI-CS) requiring interhospital transfer, as well as the prognostic impact of structural variables of the treating centers in this setting. METHODS: This study included patients with STEMI-CS treated at revascularization-capable centers from 2016 to 2020. The patients were divided into the following groups: group A: patients attended throughout their admission at hospitals with interventional cardiology without cardiac surgery; group B: patients treated at hospitals with interventional cardiology and cardiac surgery; and group C: patients transferred to centers with interventional cardiology and cardiac surgery. We analyzed the association between the volume of STEMI-CS cases treated, the availability of cardiac intensive care units (CICU), and heart transplant with hospital mortality. RESULTS: A total of 4189 episodes were included: 1389 (33.2%) from group A, 2627 from group B (62.7%), and 173 from group C (4.1%). Transferred patients were younger, had a higher cardiovascular risk, and more commonly underwent revascularization, mechanical circulatory support, and heart transplant during hospitalization (P<.001). The crude mortality rate was lower in transferred patients (46.2% vs 60.3% in group A and 54.4% in group B, (P<.001)). Lower mortality was associated with a higher volume of care and CICU availability (OR, 0.75, P=.009; and 0.80, P=.047). CONCLUSIONS: The proportion of transfers in patients with STEMI-CS in our setting is low. Transferred patients were younger and underwent more invasive procedures. Mortality was lower among patients transferred to centers with a higher volume of STEMI-CS cases and CICU.

Intravascular imaging-guided percutaneous coronary intervention in patients with acute myocardial infarction and cardiogenic shock.

INTRODUCTION AND OBJECTIVES: There are no clinical data on the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI in patients with acute myocardial infarction (AMI) and cardiogenic shock. The current study sought to evaluate the impact of intravascular imaging-guided PCI in patients with AMI and cardiogenic shock. METHODS: Among a total of 28 732 patients from the nationwide pooled registry of KAMIR-NIH (November, 2011 to December, 2015) and KAMIR-V (January, 2016 to June, 2020), we selected a total of 1833 patients (6.4%) with AMI and cardiogenic shock who underwent PCI of the culprit vessel. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of cardiac death, myocardial infarction, repeat revascularization, and definite or probable stent thrombosis. RESULTS: Among the study population, 375 patients (20.5%) underwent intravascular imaging-guided PCI and 1458 patients (79.5%) underwent angiography-guided PCI. Intravascular imaging-guided PCI was associated with a significantly lower risk of 1-year MACE than angiography-guided PCI (19.5% vs 28.2%; HR, 0.59; 95%CI, 0.45-0.77; P<.001), mainly driven by a lower risk of cardiac death (13.7% vs 24.0%; adjusted HR, 0.53; 95%CI, 0.39-0.72; P<.001). These results were consistent in propensity score matching (HR, 0.68; 95%CI, 0.46-0.99), inverse probability weighting (HR, 0.61; 95%CI, 0.45-0.83), and Bayesian analysis (Odds ratio, 0.66, 95% credible interval, 0.49-0.88). CONCLUSIONS: In AMI patients with cardiogenic shock, intravascular imaging-guided PCI was associated with a lower risk of MACE at 1-year than angiography-guided PCI, mainly driven by the lower risk of cardiac death.

The medical treatment of cardiogenic shock.

Cardiogenic shock is characterized by tissue hypoperfusion due to the inadequate cardiac output to maintain the tissue oxygen demand. Despite some advances in cardiogenic shock management, extremely high mortality is still associated with this clinical syndrome. Its management is based on the immediate stabilization of hemodynamic parameters through medical care and the use of mechanical circulatory supports in specialized centers. This review aims to understand the cardiogenic shock current medical treatment, consisting mainly of inotropic drugs, vasopressors and coronary revascularization. In addition, we highlight the relevance of applying measures to other organ levels based on the optimization of mechanical ventilation and the appropriate initiation of renal replacement therapy.

Cardiogenic shock complicating acute myocardial infarction and multivessel disease: revascularization strategy according to ischemic territory.

INTRODUCTION AND OBJECTIVES: The association of revascularization strategy with clinical outcomes according to the ischemic territory of nonculprit lesion has not been documented in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). This study aimed to compare outcomes between culprit-only and immediate multivessel percutaneous coronary intervention (PCI) according to ischemic territory in patients with AMI-CS. METHODS: A total of 536 patients with AMI-CS and multivessel disease from the SMART-RESCUE registry were categorized according to ischemic territory (nonculprit left main/proximal left anterior descending artery [LM/pLAD] vs culprit LM/pLAD vs no LM/pLAD). The primary outcome was a patient-oriented composite endpoint (POCE) consisting of all-cause death, myocardial infarction, rehospitalization due to heart failure, or repeat revascularization at 1 year. RESULTS: Among the total population, 108 patients had nonculprit LM/pLAD, 228 patients had culprit LM/pLAD, and 200 patients had no LM/pLAD, with the risk of POCE being higher in patients with large ischemic territory lesions (53.6% vs 53.4% vs 39.6%; P = .02). Multivessel PCI was associated with a significantly lower risk of POCE compared with culprit-only PCI in patients with nonculprit LM/pLAD (40.7% vs 66.9%; HR, 0.52; 95%CI, 0.29-0.91; P=.02), but not in those with culprit LM/pLAD (P=.46) or no LM/pLAD (P=.47). A significant interaction existed between revascularization strategy and large nonculprit ischemic territory (P=.03). CONCLUSIONS: Large ischemic territory involvement was associated with worse clinical outcomes in patients with AMI-CS and multivessel disease. Immediate multivessel PCI might improve clinical outcomes in patients with a large nonculprit ischemic burden.

Cardiogenic shock as a health issue. Physiology, classification, and detection.

Cardiogenic shock (CS) is a heterogeneous syndrome with high mortality and a growing incidence. It is characterized by an imbalance between the tissue oxygen demands and the capacity of the cardiovascular system to meet these demands, due to acute cardiac dysfunction. Historically, acute coronary syndromes have been the primary cause of CS. However, non-ischemic cases have seen a rise in incidence. The pathophysiology involves ischemic damage of the myocardium and a sympathetic, renin-angiotensin-aldosterone system and inflammatory response, perpetuating the situation of tissue hypoperfusion and ultimately leading to multiorgan dysfunction. The characterization of CS patients through a triaxial assessment and the widespread use of the Society for Cardiovascular Angiography and Interventions (SCAI) scale has allowed standardization of the severity stratification of CS; this, coupled with early detection and the "hub and spoke" approach, could contribute to improving the prognosis of these patients.

Efficacy of thrombus aspiration in cardiogenic shock complicating acute myocardial infarction and high thrombus burden.

INTRODUCTION AND OBJECTIVES: Current guidelines do not recommend routine thrombus aspiration in acute myocardial infarction (AMI) because no benefits were observed in previous randomized trials. However, there are limited data in cardiogenic shock (CS) complicating AMI. METHODS: We included 575 patients with AMI complicated by CS. The participants were stratified into the TA and no-TA groups based on use of TA. The primary outcome was a composite of 6-month all-cause death or heart failure rehospitalization. The efficacy of TA was additionally assessed based on thrombus burden (grade I-IV vs V). RESULTS: No significant difference was found in in-hospital death (28.9% vs 33.5%; P=.28), or 6-month death, or heart failure rehospitalization (32.4% vs 39.4%; HRadj: 0.80; 95%CI, 0.59-1.09; P=.16) between the TA and no-TA groups. However, in 368 patients with a higher thrombus burden (grade V), the TA group had a significantly lower risk of 6-month all-cause death or heart failure rehospitalization than the no-TA group (33.4% vs 46.3%; HRadj: 0.59; 95%CI, 0.41-0.85; P=.004), with significant interaction between thrombus burden and use of TA for primary outcome (adjusted Pint=.03). CONCLUSIONS: Routine use of TA did not reduce short- and mid-term adverse clinical outcomes in patients with AMI complicated by CS. However, in select patients with a high thrombus burden, the use of TA might be associated with improved clinical outcomes. The study was registered at ClinicalTrials.gov (Identifier: NCT02985008).

Cardiogenic shock code 2023. Expert document for a multidisciplinary organization that allows quality care.

Despite the efforts made to improve the care of cardiogenic shock (CS) patients, including the development of mechanical circulatory support (MCS), the prognosis of these patients continues to be poor. In this context, CS code initiatives arise, based on providing adequate, rapid, and quality care to these patients. In this multidisciplinary document we try to justify the need to implement the SC code, defining its structure/organization, activation criteria, patient flow according to care level, and quality indicators. Our specific purposes are: a) to present the peculiarities of this condition and the lessons of infarction code and previous experiences in CS; b) to detail the structure of the teams, their logistics and the bases for the management of these patients, the choice of the type of MCS, and the moment of its implantation, and c) to address challenges to SC code implementation, including the uniqueness of the pediatric SC code. There is an urgent need to develop protocolized, multidisciplinary, and centralized care in hospitals with a large volume and experience that will minimize inequity in access to the MCS and improve the survival of these patients. Only institutional and structural support from the different administrations will allow optimizing care for CS.

Anti-endotoxin antibodies consumption in cardiovascular collapse: Pathophysiological concerns.

OBJECTIVE: Abnormal endotoxin activity in critically ill patients has been described in the absence of Gram-negative bacterial (GNB) infection. As disease severity seems to be crucial in the detection of this phenomenon, we decided to assess and compare endotoxin exposure in those patients representing the critical situation: septic shock and cardiogenic shock. DESIGN: Prospective, observational non intervention study. SETTING: Critical Care Department of a University tertiary hospital. PATIENTS: Cardiogenic shock (CS) and septic shock (SS) patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Follow-up was performed for the first three days. Inflammatory biomarkers (C-reactive protein, procalcitonin and interleuquin-6) and IgM antiendotoxin-core antibodies titter (IgM EndoCAb) were daily analyzed. Sixty-two patients were included; twenty-five patients with SS and thirty-seven with CS. Microbial etiology was established in 23 SS patients (92%) and GNB were present in 13 cases (52%). Although infection was suspected and even treated in 30 CS patients (81%), any episode could be finally confirmed. EndoCAb consumption was more intense in SS patients, although twenty-two CS patients (59.5%) had IgM anti-endotoxin value below 10th percentile range for healthy people. No statistically significant difference in endotoxin exposure was detected between Gram-positive and Gram-negative infections in the SS group. Endotoxin exposure ability to distinguish between SS and CS was moderate (AUC 0.7892, 95% IC: 0.6564-0.9218). CONCLUSIONS: In the severely ill patient some mechanisms take place allowing endotoxin incursion and therefore blurring the limits of diseases pathophysiology. Our work representatively shows how exposure to endotoxin was not fully capable of distinguishing between CS and SS.

A possible role for the venous-to-arterial CO2 difference in cardiogenic shock: an exploratory study. / Estudio exploratorio del rol de la diferencia venoarterial de dióxido de carbono en el shock cardiogénico.

OBJECTIVES: The venous-to-arterial CO2 partial pressure difference (CO2) is a marker of how adequately capillary blood flow is able to remove CO2 from tissues, but evidence regarding its usefulness in patients with cardiogenic shock (CS) is scarce The main objective of this study was to describe the changes in CO2 in patients with cardiogenic shock during the 48 hours after hospital admission. A secondary objective was to analyze the association between CO2 and in-hospital mortality due to cardiovascular disease (CVD) and cardiogenic shock refractory to treatment. MATERIAL AND METHODS: Prospective observational exploratory study in a single hospital. Patients in cardiogenic shock who were admitted to a cardiology critical care unit were included. We measured CO2 on inclusion and 6, 12, 24, and 48 hours after admission to the unit. Variables were explored with logistic regression analysis and areas under the receiver operating characteristic curves were calculated. RESULTS: A total of 50 patients were included. In-hospital mortality due to CVD was 20%. CO2 peaked initially and decreased gradually over the first 48 hours of care. In-hospital mortality tended to be higher in patients with the highest CO2 values, but the difference was not significant. High CO2 values at 24 hours were associated with refractory cardiogenic shock. The negative predictive value of a CO2 value lower than 6 mmHg at 12 hours was 87% for mortality due to CVD. CONCLUSION: This exploratory study suggests that CO2 could be a helpful additional marker to measure when managing cardiogenic shock. CO2 lower than 6 mmHg between 12 and 24 hours after admission may identify patients at low risk of death due to CVD or refractory cardiogenic shock.

OBJETIVO: La diferencia venoarterial de dióxido de carbono (CO2) representa la adecuación del flujo capilar para eliminar CO2 tisular, sin embargo, su evidencia en pacientes con shock cardiogénico (SC) es escasa. El objetivo primario fue caracterizar la cinética de la diferencia venoarterial de CO2 en pacientes con SC durante las primeras 48 horas de ingreso. El objetivo secundario fue analizar la asociación de la CO2 con la mortalidad intrahospitalaria de causa cardiovascular y el SC refractario. METODO: Estudio exploratorio, observacional, prospectivo y unicéntrico. Se incluyeron pacientes en SC ingresados en una unidad de cuidados críticos cardiológicos. Se determinó la CO2 a la inclusión, a las 6, 12, 24 y 48 horas y se realizó un análisis de regresión logística y curvas de la característica operativa del receptor. RESULTADOS: Se incluyeron 50 pacientes. La mortalidad cardiovascular intrahospitalaria fue del 20%. La cinética de la CO2 mostró un pico inicial y un progresivo descenso durante las primeras 48 horas. Los pacientes con valores más altos de CO2 tuvieron una mayor mortalidad cardiovascular intrahospitalaria, pero esta diferencia no fue significativa. A las 24 horas, valores elevados de CO2 se asociaron significativamente con SC refractario. Un valor inferior a 6 mmHg a las 12 horas mostró un valor predictivo negativo del 87% para mortalidad cardiovascular. CONCLUSIONES: Este estudio exploratorio sugiere la potencial utilidad de la CO2 como biomarcador adicional en el manejo del SC. La CO2 permite identificar pacientes con bajo riesgo de mortalidad cardiovascular y SC refractario cuando sus valores son inferiores a 6 mmHg a las 12-24 horas de evolución.

Outcomes of a multidisciplinary mechanical circulatory support network in cardiogenic shock in a centre without heart transplant program: A successful interprofessional coordination model.

BACKGROUND AND OBJECTIVE: Cardiogenic shock (CS) mortality remains very high and mechanical circulatory support (MCS) may provide an effective alternative of treatment in selected patients. The aim of this study is to analyse the results of a multidisciplinary team care program (including anaesthesiologists, cardiologists, cardiothoracic surgeons, and intensivists) in CS patients who required MCS, in a tertiary centre without a heart transplant (HT) program. METHODS: Prospective observational study that sought to analyse the characteristics and survival to discharge predictors in a consecutive CS patients cohort treated with MCS. RESULTS: A total of 48 patients were included. Mean age was 61 ± 14 years. Before MCS, 45.8% of the patients presented with cardiac arrest. A 54.2% 30-day survival and 45.8% overall survival to discharge, was found. Age and vasoactive-inotropic score were independent predictors of mortality. CONCLUSIONS: A multidisciplinary team-care based MCS program in CS patients is feasible and may achieve favourable results in a centre without HT program.

Lactate levels as a prognostic predict in cardiogenic shock under venoarterial extracorporeal membrane oxygenation support.

INTRODUCTION AND OBJECTIVES: Lactate and its evolution are associated with the prognosis of patients in shock, although there is little evidence in those assisted with an extracorporeal venoarterial oxygenation membrane (VA-ECMO). Our objective was to evaluate its prognostic value in cardiogenic shock assisted with VA-ECMO. METHODS: Study of patients with cardiogenic shock treated with VA-ECMO for medical indication between July 2013 and April 2021. Lactate clearance was calculated: [(initial lactate - 6 h lactate) / initial lactate × exact time between both determinations]. RESULTS: From 121 patients, 44 had acute myocardial infarction (36.4%), 42 implant during cardiopulmonary resuscitation (34.7%), 14 pulmonary embolism (11.6%), 14 arrhythmic storm (11.6%), and 6 fulminant myocarditis (5.0%). After 30 days, 60 patients (49.6%) died, mortality was higher for implant during cardiopulmonary resuscitation than for implant in spontaneous circulation (30 of 42 [71.4%] vs 30 of 79 [38.0%], P=.030). Preimplantation GPT and lactate (both baseline, at 6hours, and clearance) were independently associated with 30-day mortality. The regression models that included lactate clearance had a better predictive capacity for survival than the ENCOURAGE and ECMO-ACCEPTS scores, with the area under the ROC curve being greater in the model with lactate at 6 h. CONCLUSIONS: Lactate (at baseline, 6h, and clearance) is an independent predictor of prognosis in patients in cardiogenic shock supported by VA-ECMO, allowing better risk stratification and predictive capacity.

Usefulness of severity scales for cardiogenic shock in-hospital mortality. Proposal for a new prognostic model.

Cardiogenic shock (CS) is a condition comprising multiple etiologies, which associates high mortality rates. Some scoring systems have been shown to be good predictors of hospital mortality in patients admitted to Critical Care Units (CCU). The main objective of this study is to analyze their usefulness and validity in a cohort of CS patients. METHODS: Observational unicentric study of a cohort of CS patients. SOFA, SAPS II and APACHE II scores were calculated in the first 24 h of CCU admission. RESULTS: 130 patients with CS were included. SOFA, SAPS II and APACHE II scores revealed good discrimination for hospital mortality: (AUC) ROC values (AUC: 0.711, 0.752 and 0.742 respectively; P = .6). Calibration, estimated by the Hosmer-Lemeshow test, was adequate in all cases. Acute coronary syndrome, lactate serum values, SAPS II score and vasoactive inotropic score (VIS) were found to be independent predictors for mortality, upon ICU admission. With these variables, a specific prognostic indicator was developed (SAPS-2-LIVE), which improved predictive capability for mortality in our series (AUC) ROC, 0.825 (95% CI 0.752-0.89). CONCLUSION: In this contemporary CS cohort, the aforementioned scores have been shown to have good predictive ability for hospital mortality. These findings could contribute to a more accurate risk stratification in CS.

Mixed shock in patients with acute myocardial infarction: Nursing interventions.

INTRODUCTION AND OBJECTIVES: We present a clinical case of a 40-year-old woman diagnosed with acute myocardial infarction (AMI) in Killip I who was admitted to our hospital. She experienced complications in the haemodynamic lab and in the operating room, including cardiogenic and anaphylactic shock requiring ventricular assist support. Conservative management support with inotropes and vasopressors in cardiogenic shock has been shown to be insufficient in many patients to maintain adequate perfusion and prevent irreversible multiple organ dysfunction syndrome. For this reason, short-term mechanical circulatory support systems are increasing substantially. The objective of this article is to develop optimal and individualised care plans using the NANDA, NOC, NIC taxonomies. CLINICAL OBSERVATION: An evaluation based on Virginia Henderson's basic needs was made, and two altered needs stood out: breathing and circulation. The patient required mechanical ventilation and mechanical circulatory support. INTERVENTIONS: In relation to the highlighted needs, six diagnoses were prioritized according to the NANDA taxonomy using the Análisis de Resultado del Estado Actual (AREA) (Outcome-Present State Test (OPT)) model: risk of decreased cardiac output, impaired spontaneous ventilation, impaired tissue integrity, risk of disuse syndrome, risk of infection and risk of hypothermia. DISCUSSION AND CONCLUSIONS: Outcome criteria scores showed a favourable evolution after 96 h. The development of a standardized NANDA-NOC-NIC language allowed us to organize the nursing care plan.

Ivabradine induces cardiac protection by preventing cardiogenic shock-induced extracellular matrix degradation.

INTRODUCTION AND OBJECTIVES: Ivabradine reduces heart rate by blocking the I(f) current and preserves blood pressure and stroke volume through unknown mechanisms. Caveolin-3 protects the heart by forming protein complexes with several proteins, including extracellular matrix (ECM)-metalloproteinase-inducer (EMMPRIN) and hyperpolarization-activated cyclic nucleotide-gated channel 4 (HN4), a target of ivabradine. We hypothesized that ivabradine might also exert cardioprotective effects through inhibition of ECM degradation. METHODS: In a porcine model of cardiogenic shock, we studied the effects of ivabradine on heart integrity, the levels of MMP-9 and EMMPRIN, and the stability of caveolin-3/HCN4 protein complexes with EMMPRIN. RESULTS: Administration of 0.3 mg/kg ivabradine significantly reduced cardiogenic shock-induced ventricular necrosis and expression of MMP-9 without affecting EMMPRIN mRNA, protein, or protein glycosylation (required for MMP activation). However, ivabradine increased the levels of the caveolin-3/LG-EMMPRIN (low-glycosylated EMMPRIN) and caveolin-3/HCN4 protein complexes and decreased that of a new complex between HCN4 and high-glycosylated EMMPRIN formed in response to cardiogenic shock. We next tested whether caveolin-3 can bind to HCN4 and EMMPRIN and found that the HCN4/EMMPRIN complex was preserved when we silenced caveolin-3 expression, indicating a direct interaction between these 2 proteins. Similarly, EMMPRIN-silenced cells showed a significant reduction in the binding of caveolin-3/HCN4, which regulates the I(f) current, suggesting that, rather than a direct interaction, both proteins bind to EMMPRIN. CONCLUSIONS: In addition to inhibition of the I(f) current, ivabradine may induce cardiac protection by inhibiting ECM degradation through preservation of the caveolin-3/LG-EMMPRIN complex and control heart rate by stabilizing the caveolin-3/HCN4 complex.

SEDAR/SECCE ECMO management consensus document.

ECMO is an extracorporeal cardiorespiratory support system whose use has been increased in the last decade. Respiratory failure, postcardiotomy shock, and lung or heart primary graft failure may require the use of cardiorespiratory mechanical assistance. In this scenario perioperative medical and surgical management is crucial. Despite the evolution of technology in the area of extracorporeal support, morbidity and mortality of these patients continues to be high, and therefore the indication as well as the ECMO removal should be established within a multidisciplinary team with expertise in the area. This consensus document aims to unify medical knowledge and provides recommendations based on both the recent bibliography and the main national ECMO implantation centres experience with the goal of improving comprehensive patient care.

Initial outcomes of a multidisciplinary network for the care of patients with cardiogenic shock.

INTRODUCTION AND OBJECTIVES: Mortality remains high in cardiogenic shock (CS), especially in refractory CS involving the use of mechanical circulatory support (MCS) devices. The aim of this study was to analyze the results of a care program for patients in CS after the creation of a multidisciplinary team in our center and a regional network of hospitals in our area. METHODS: Observational and retrospective study of patients attended in this program from September 2014 to January 2019. We included patients in refractory CS who required MCS and those who, because of their age and absence of comorbidities, were candidates for advanced therapies. The primary endpoint was survival to discharge. RESULTS: A total of 130 patients were included (69 local and 61 transferred patients). The mean age was 52±15 years (72% men). The most frequent causes of CS were acute decompensated heart failure (29%), acute myocardial infarction (26%), and postcardiotomy CS (25%). MCS was used in 105 patients (81%), mostly extracorporeal membrane oxygenation (58%). Survival to discharge was 57% (74 of 130 patients). The most frequent destinations were myocardial recovery and heart transplant. Independent predictors of in-hospital mortality were SAPS II score, lactate level, acute myocardial infarction etiology, and vasoactive-inotropic score. CONCLUSIONS: The creation of multidisciplinary teams for patients with mainly refractory CS and a regional network is feasible and allows survival to discharge in more than a half of attended patients with CS.

Temporal trends in postinfarction ventricular septal rupture: the CIVIAM Registry.

INTRODUCTION AND OBJECTIVES: Postinfarction ventricular septal rupture is a rare but severe complication of myocardial infarction with high mortality rates. Our goal was to analyze which factors could have an impact on mortality due to this entity over the past decade, including those related to mechanical circulatory support. METHODS: The CIVIAM registry is an observational, retrospective, multicenter study carried out in Spain. We designed a comparative analysis, focused on description of in-hospital management and in-hospital and 1-year total mortality as the primary endpoints, dividing the total observation time into 2 equal temporal periods (January 2008 to June2013 and July 2013 to December 2018). RESULTS: We included 120 consecutive patients. Total mortality during this period was 61.7% at 1-year follow-up. Patients in the second period were younger. One-year mortality was significantly reduced in the second period (75.6% vs 52.7%, P=.01), and this result was confirmed after adjustment by confounding factors (OR, 0.40; 95%CI, 0.17-0.98). Surgical repair was attempted in 58.7% vs 70.3%, (P=.194), and percutaneous closure in 8.7% and 6.8%, respectively (P=.476). Heart transplant was performed in 1 vs 5 patients (2.2% vs 6.8%, P=.405). The main difference in the clinical management between the 2 periods was the greater use of venoarterial extracorporeal membrane oxygenatiom in the second half of the study period (4.4% vs 27%; P=.001). CONCLUSIONS: Postinfarction ventricular septal rupture still carries a very high mortality risk. There has been a progressive trend to increased support with venoarterial extracorporeal membrane oxygenatiom and greater access to available corrective treatments, with higher survival rates.
