The management of heart failure cardiogenic shock: an international RAND appropriateness panel. Crit Care 2024; 28:105. [PMID: 38566212 PMCID: PMC10988801 DOI: 10.1186/s13054-024-04884-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 03/20/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Observational data suggest that the subset of patients with heart failure related CS (HF-CS) now predominate critical care admissions for CS. There are no dedicated HF-CS randomised control trials completed to date which reliably inform clinical practice or clinical guidelines. We sought to identify aspects of HF-CS care where both consensus and uncertainty may exist to guide clinical practice and future clinical trial design, with a specific focus on HF-CS due to acute decompensated chronic HF. METHODS A 16-person multi-disciplinary panel comprising of international experts was assembled. A modified RAND/University of California, Los Angeles, appropriateness methodology was used. A survey comprising of 34 statements was completed. Participants anonymously rated the appropriateness of each statement on a scale of 1 to 9 (1-3 as inappropriate, 4-6 as uncertain and as 7-9 appropriate). RESULTS Of the 34 statements, 20 were rated as appropriate and 14 were rated as inappropriate. Uncertainty existed across all three domains: the initial assessment and management of HF-CS; escalation to temporary Mechanical Circulatory Support (tMCS); and weaning from tMCS in HF-CS. Significant disagreement between experts (deemed present when the disagreement index exceeded 1) was only identified when deliberating the utility of thoracic ultrasound in the immediate management of HF-CS. CONCLUSION This study has highlighted several areas of practice where large-scale prospective registries and clinical trials in the HF-CS population are urgently needed to reliably inform clinical practice and the synthesis of future societal HF-CS guidelines.

Abstract
Impella and intra-aortic balloon pumps (IABP) are commonly utilized in patients with cardiogenic shock. However, the effect on mortality remains controversial. The goal of this study was to evaluate the effect of Impella and IABP on mortality in patients with cardiogenic shock the large Nationwide Inpatient Sample (NIS) database was utilized to study any association between the use of IABP or Impella on outcome. ICD-10 codes for Impella, IABP, and cardiogenic shock for available years 2016-2020 were utilized. A total of 844,020 patients had a diagnosis of cardiogenic shock. A total of 101,870 patients were treated with IABP and 39645 with an Impella. Total inpatient mortality without any device was 34.2% vs only 25.1% with IABP use (OR = 0.65, CI 0.62-0.67) but was highest at 40.7% with Impella utilization (OR = 1.32, CI 1.26-1.39). After adjusting for 47 variables, Impella utilization remained associated with the highest mortality (OR: 1.33, CI 1.25-1.41, p < 0.001), whereas IABP remained associated with the lowest mortality (OR: 0.69, CI 0.66-0.72, p < 0.001). Separating rural vs teaching hospitals revealed similar findings. In patients with cardiogenic shock, the use of Impella was associated with the highest whereas IABP was associated with the lowest in-hospital mortality regardless of comorbid condition.

Abstract
Multisystem inflammatory syndrome in children is a rare and potentially life-threatening disease that is associated with SARS-CoV-2 infection, characterized by hyperinflammation and multiorgan involvement. Cardiovascular involvement is common, including myocardial dysfunction often leading to cardiogenic shock. We present the case of a 17-year-old boy with fever, odynophagia, maculopapular rash and abdominal pain who developed a cardiogenic shock. Due to progressive deterioration of cardiac function despite optimized vasoactive support, veno-arterial extracorporeal membrane oxygenation support was initiated 12 hours after admission, with successful decannulation after seven days and discharge after 23 days, with normal cardiac function. The patient received corticosteroids and intravenous immunoglobulin. Early recognition and intensive care support are crucial for ensuring a successful outcome in severe cases of multisystem inflammatory syndrome. In cases of severe cardiogenic shock, extracorporeal membrane oxygenation support can be critical for survival and rapid recovery.

Abstract
Background VA-ECMO with concomitant Impella support (ECpella) is an emerging treatment modality for cardiogenic shock (CS). Survival outcomes by CS etiology with ECpella support have not been well-described. Methods This study was a retrospective, single-center analysis of patients with cardiogenic shock due to acute myocardial infarction (AMI-CS) or decompensated heart failure (ADHF-CS) supported with ECpella from December 2020 to January 2023. Primary outcomes included 90-day survival post-discharge and destination after support. Secondary outcomes included complications post-ECpella support. Results A total of 44 patients were included (AMI-CS, n = 20, and ADHF-CS, n = 24). Patients with AMI-CS and ADHF-CS had similar survival 90 days post-discharge (p = .267) with similar destinations after ECpella support (p = .220). Limb ischemia and acute kidney injury occurred more frequently in patients presenting with AMI-CS (p=.013; p = .030). Patients with initial Impella support were more likely to survive ECpella support and be bridged to transplant (p=.033) and less likely to have a cerebrovascular accident (p=.016). Sub-analysis of ADHF-CS patients into acute-on-chronic decompensated heart failure and de novo heart failure demonstrated no difference in survival or destination. Conclusion ECpella can be used to successfully manage patients with CS. There is no difference in survival or destination for AMI-CS and ADHF-CS in patients with ECpella support. Patients with initial Impella support are more likely to survive ECpella support and bridge to transplant. Future multicenter studies are required to fully analyze the differences between AMI-CS and ADHF-CS with ECpella support.

Abstract
INTRODUCTION The Impella ventricular support system is a device that can be inserted percutaneously or directly across the aortic valve to unload the left ventricle. The purpose of this study is to determine the role of Impella devices in patients with acute cardiogenic shock in the perioperative period of cardiac surgery. METHODS A retrospective single-surgeon review of 11 consecutive patients who underwent placement of Impella devices in the perioperative period of cardiac surgery was performed. Patient records were evaluated for demographics, indications for placement, and postoperative outcomes. RESULTS Impella devices were placed for refractory cardiogenic shock preoperatively in 6 patients, intraoperatively in 4 patients, and postoperatively as a rescue in 1 patient. Seven patients received Impella CP, 1 Impella RP, 1 Impella CP and RP, and 2 Impella 5.0. Additionally, 3 patients required preoperative venovenous extracorporeal membrane oxygenation (VV-ECMO), and 1 patient required intraoperative venoarterial extracorporeal membrane oxygenation (VA-ECMO). All Impella devices were removed 1 to 28 days after implantation. Length of stay in the intensive care unit stay ranged from 2 to 53 days (average 23.9±14.6). The 30-day and 1-year mortality were 0%. Ten of 11 patients were alive at 2 years. Also, 1 patient died 18 months after surgery from complications of coronavirus disease (Covid-19). Device-related complications included varying degrees> of hemolysis in 8 patients (73%) and device malfunction in 1 patient (9%). CONCLUSIONS The Impella ventricular support system can be combined with other mechanical support devices for additional hemodynamic support. All patients demonstrated myocardial recovery with no deaths in the perioperative period and in 1-year of follow-up. Larger studies are necessary to validate these findings.

Abstract
INTRODUCTION This study analyzes the outcome of a protocol-based surgical approach for ventricular septal rupture (VSR). The study also clarifies the appropriate time for intervention. METHODS This is a single-center retrospective analysis of all VSR cases evaluated between February 2006 and March 2020. Cases were managed using the same protocol. Patients were divided into two cohorts - early (those in whom our protocol was instituted within 24 hours of diagnosis) and delayed (intervention between 24 hours and seven days after diagnosis). All-cause mortality was considered as the outcome. RESULTS The mean age of presentation was 60.1 years, and 75.9% of the patients were men. Cardiogenic shock was the most common mode of presentation. Our analysis validates that once a patient develops VSR, age, sex, comorbidities, left ventricular function, and renal failure at the time of presentation do not have a statistically significant impact on the outcome. The sole factor to have an impact on the outcome was time of intervention. All patients in the delayed cohort expired after surgery, which dragged the overall mortality to 34.5%, whereas 95% of patients in the early cohort are still on follow-up. The mortality in this group was 5% (P≤0.001). CONCLUSION Early surgical intervention has proven benefits over delayed approach. Surgical intervention in the early part of the disease reduces the risk and thus improves the outcome. The extreme rarity makes VSR an uncommon entity among surgeons. A protocol-based approach makes the team adapt to this unfamiliar situation better.

Abstract
Rates of stress (Takotsubo) cardiomyopathy have increased during the coronavirus pandemic due to social stressors, even in patients who are not infected with the virus. At times, Takotsubo cardiomyopathy (TC) may present as cardiogenic shock. Herein, we present a case during the pandemic of shock from TC secondary to left ventricular outflow tract obstruction (LVOTO), mitral regurgitation (MR), and left ventricular (LV) dysfunction. The contrasting management strategy of LVOTO, MR, and LV failure was cause for clinical challenge, and we highlight the balance of treating these opposing forces.

Abstract
SARS-CoV-2 pandemics is characterized by a high level of infectivity and a high mortality among adults at risk (older than 65 years, obesity, diabetes, systemic hypertension). Following a common viral pneumonia, a multisystem inflammatory syndrome sometimes occurs, including an Acute Respiratory Distress Syndrome (ARDS) carrying a high mortality. Unlike most common respiratory viruses, children seem less susceptible to SARS-CoV-2 infection and generally develop a mild disease with low mortality. However, clusters of severe shock associated with high levels of cardiac biomarkers and unusual vasoplegia requiring inotropes, vasopressors and volume loading have been recently described. Both clinical symptoms (i.e., high and persistent fever, gastrointestinal disorders, skin rash, conjunctivitis and dry cracked lips) and biological signs (e.g., elevated CRP/PCT, hyperferritinemia) resembled Kawasaki disease. In most instances, intravenous immunoglobin therapy improved the cardiac function and led to full recovery within a few days. However, adjunctive steroid therapy and sometimes biotherapy (e.g., anti-IL-1Ra, anti-IL-6 monoclonal antibodies) were often necessary. Although almost all children fully recovered within a week, some of them developed coronary artery dilation or aneurysm. Thus, a new 'Multisystem Inflammatory Syndrome associated with SARS-CoV-2' has been recently described in children and helps to better understand Kawasaki disease pathophysiology.

Abstract
Cardiogenic shock as the initial manifestation of systemic lupus erythematosus (SLE) is an uncommon but catastrophic complication. Because of the lack of typical clinical features, the diagnosis of the disease is challenging. This case report describes a 47‐year‐old female admitted to the emergency room in refractory cardiogenic shock with dilative cardiomyopathy and a left ventricular ejection fraction (LVEF) of 25.6% of unknown origin. The patient responded poorly to the initial tries of stabilization, and the clinical status continued to deteriorate. Venous–arterial extracorporeal membrane oxygenation (V‐A ECMO) was applied to maintain hemodynamic stability. Coronary angiography revealed no obvious stenosis of the coronary artery. Evidence of virus infection was negative. After requestioning about medical history in detail, Reynaud's phenomenon was shown. SLE was suspected. A complete autoimmune laboratory workup was completed and found the positive result of antinuclear antibodies, anti‐double‐stranded DNA antibodies, anti‐phospholipid antibodies, and low C3 and C4. The patient also presented with pericardial effusion and the PLTs <100 000/mm3. SLE was confirmed according to the 2019 EULAR/ACR criteria. When the diagnosis was established, the immunotherapy was initiated. As a result, the patient underwent a quick recovery and achieved good outcomes. In conclusion, early diagnosis and timely application of immunotherapy is the key to treatment lupus myocarditis. Advanced mechanical support may play a necessary role when patient is in critical situation. For middle‐aged female patients presenting with unexplained cardiogenic shock, lupus myocarditis should be considered in the differential diagnosis. In addition, the 2019 EULAR/ACR criteria provide a new, fitting tool for the diagnosis, which is conducive to the earlier and more accurate diagnosis of SLE.

Abstract
OBJECTIVES To investigate the baseline risk of patients treated with Extracorporeal Cardiopulmonary Membrane Oxygenation (ECMO) in relation to cannulation strategy and indication for ECMO as well as the relation of cannulation strategy with survival and secondary hospitalization outcomes. METHODS Severity of illness and predicted mortality risk were assessed in 317 patients. Central cannulation was used in 52 patients unable to wean off cardiopulmonary bypass after cardiac surgery. Peripheral cannulation was used in 179 patients for extracorporeal cardiopulmonary resuscitation (eCPR) and in 86 patients who received ECMO for refractory cardiogenic shock (RCS). RESULTS Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were significantly worse (P < 0.01) for peripheral ECMO eCPR (23.2) vs central ECMO (14.6) and vs peripheral ECMO for RCS (18.9). Survival After Venoarterial ECMO (SAVE) scores were significantly worse for peripheral ECMO for eCPR (-7.85) and RCS (-10.38) vs central ECMO (-3.97), and P < 0.01. Peripherally cannulated patients had significantly worse renal function. No significant difference existed for survival to discharge (peripheral ECMO for eCPR, 31%; central ECMO, 44%; peripheral ECMO for refractory cardiac shock, 39.5%; and P = 0.176), although centrally cannulated patients had significantly longer treatment durations compared with peripheral ECMO for eCPR. CONCLUSIONS Peripherally cannulated patients with eCPR had significantly worse APACHE II and SAVE scores compared to peripherally cannulated RCS or patients with central ECMO, despite having similar mortality.

Abstract
Objective To evaluate the relative incidence of cardiogenic and septic shock in term neonates and identify findings that help differentiate the two entities. Study Design We conducted a retrospective chart review of term neonates presenting to British Columbia Children's Hospital (BCCH) with decompensated shock of an undiagnosed etiology between January 1, 2008 and January 1, 2013. Charts were reviewed to determine the underlying diagnoses of all neonates meeting our inclusion criteria. Patients were categorized as having septic, cardiogenic, or other etiologies of shock. We then evaluated potential demographic, clinical, and biochemical parameters that could help differentiate between septic and cardiogenic shock. Results Cardiogenic shock was more common than septic shock (relative risk=1.53). A history of cyanosis was suggestive of cardiogenic shock (positive likelihood ratio, LR+=3.2 and negative likelihood ratio, LR-=0.4). Presence of a murmur or gallop (LR+=5.4, LR-=0.3), or decreased femoral pulses (LR+=5.1, LR-=0.5) on physical exam were also suggestive of cardiogenic shock as was cardiomegaly on chest x-ray (LR+=4.9, LR-=0.5). Notably, temperature instability (LR+=0.7, LR-=1.8) and white blood cell count elevation or depression (LR+=0.8, LR-=1.1) were all poor predictors of septic shock. Conclusion Cardiogenic shock is a more common cause of decompensated shock than septic shock. A history of cyanosis, murmur or gallop, or decreased femoral pulses on exam and cardiomegaly on chest x-ray are useful indicators of cardiogenic shock. In evaluating the neonate with decompensated shock, early consideration for Cardiology consultation and interventions to treat the underlying condition is warranted.

Abstract
Inotropes are medications that improve the contractility of the heart and are used in patients with low cardiac output or evidence of end-organ dysfunction. Since their initial discovery, inotropes have held promise in alleviating symptoms and potentially increasing longevity in such patients. Decades of intensive study have further elucidated the benefits and risks of using inotropes. In this article, the authors discuss the history of inotropes, their indications, mechanism of action, and current guidelines pertaining to their use in heart failure. The authors provide insight into their appropriate use and related shortcomings and the practical aspects of inotrope use.

Abstract
Syncope is defined as a sudden, self-limited loss of consciousness and postural tone followed by spontaneous and complete recovery without any neurological sequelae. It is one of the most common paroxysmal disorders in children and adolescents. The three major causes of syncope in children are neural, cardiovascular and other non-cardiovascular causes. The common unifying mechanism is transient global hypoperfusion of the brain. The diagnosis is primarily clinical and objective laboratory investigations add little to the diagnosis in children especially in neurocardiogenic subtype. Specific management depends on the underlying cause of syncope in children. For cardiac causes, management includes early referral to the pediatric cardiology specialist. When paroxysmal non-epileptic events are suspected, child psychology or psychiatry consultation should be sought to identify the stressors and counseling. For neurocardiogenic syncope, the main objective of treatment is to prevent recurrent events to improve the quality of life, psychological stress and school absenteeism by behavior and lifestyle modifications followed by drugs in refractory cases. The prognosis is excellent for neurocardiogenic syncope and is variable based on the underlying pathology in cardiogenic cases. As syncope is not a disease in itself but a symptom of an underlying disorder; hence, all children with syncope require assessment to exclude an underlying life-threatening cardiac or non-cardiac disorder.

Abstract
Procalcitonin (PCT) is a predictive marker for the occurrence of bacterial infection and the decision to terminate antibiotic treatment in critically ill patients. An unusual increase in PCT, regardless of infection, has been observed during extracorporeal membrane oxygenation (ECMO) support. We evaluated trends and the predictive value of PCT levels in adult cardiogenic shock during treatment with ECMO. We reviewed the clinical records of 38 adult cardiogenic shock patients undergoing veno-arterial ECMO support between January 2014 and December 2016. The exclusion criteria were age <18 years, pre-ECMO infection, and less than 48 hours of support. The mean patient age was 56.7±14.7 years and 12 (31.6%) patients were female. The mean duration of ECMO support was 9.0±7.6 days. The rates of successful ECMO weaning and survival to discharge were 55.3% (n=21) and 52.6% (n=20), respectively. There were 17 nosocomial infections in 16 (42.1%) patients. Peak PCT levels (mean 25.6±9.4 ng/mL) were reached within 48 hours after initiation of ECMO support and decreased to ≤5 ng/mL within one week. The change in PCT levels was not useful in predicting the occurrence of new nosocomial infections during the ECMO run. However, a PCT level >10 ng/mL during the first week of ECMO support was significantly associated with mortality (p<0.01). The change in PCT level was not useful in predicting new infection during ECMO support. However, higher PCT levels within the first week of the ECMO run are associated with significantly higher mortality.

Abstract
Mechanical circulatory assistance has become a frequent therapeutic option for patients with advanced heart failure. For patients with acute cardiogenic shock and impaired organ function, short-term assistance with venoarterial extracorporeal membrane oxygenation is the leading therapeutic option. It enables a "bridge to decision-making" i.e. withdrawal of the device after myocardial recovery or after recognition of therapeutic futility, or as a bridge-to-transplantation or to long-term mechanical support. For Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) class 2-6 patients, implantation of a long-term ventricular assist-device (VAD) should be considered before progression to multiple organ failure if heart transplantation is not a first-line option. Most patients receive a miniaturized axial or centrifugal fully implantable left VAD as a bridge-to-transplantation or as "destination therapy" in this setting.

Abstract
Stress-induced cardiomyopathy has become a more recognized and reported entity. It can be caused by emotional or physical stress, which causes excessive catecholamine release. Typically, the clinical course is benign with conservative treatment being effective. However, stress-induced cardiomyopathy can be fatal. A 41-year-old female presented with cardiogenic shock followed by sudden back pain. Initial echocardiographic finding showed severely decreased ejection fraction with akinesia at all mid-to-apical walls with relatively preserved basal wall contractility. The coronary artery was intact on coronary angiography. Cardiac resuscitation and extra-corporeal membrane oxygenation was needed to manage the cardiogenic shock. Recovery was complete after 2 weeks.

Abstract
BACKGROUND In the SHOCK trial, an invasive strategy of early revascularization was associated with a significant mortality benefit at 6 months when compared with initial stabilization in patients with cardiogenic shock complicating acute myocardial infarction. Our objectives were to evaluate the data on real-world practice and outcomes of invasive vs conservative management in patients with cardiogenic shock. METHODS We analyzed data from the Nationwide Inpatient Sample from 2002 to 2011 with primary discharge diagnosis of acute myocardial infarction and secondary diagnosis of cardiogenic shock. Propensity score matching was used to assemble a cohort of patients managed invasively (with cardiac catheterization, percutaneous coronary intervention, or coronary artery bypass graft surgery) vs conservatively with similar baseline characteristics. The primary outcome was in-hospital mortality. RESULTS We identified 60,833 patients with cardiogenic shock, of which 20,644 patients (10,322 in each group) with similar propensity scores, including 11,004 elderly patients (≥75 years), were in the final analysis. Patients who underwent invasive management had 59% lower odds of in-hospital mortality (37.7% vs 59.7%; odds ratio [OR] 0.41; 95% confidence interval [CI], 0.39-0.43; P < .0001) when compared with those managed conservatively. This lower mortality was consistently seen across all tested subgroups; specifically in the elderly (≥75 years) (44.0% vs 63.6%; OR 0.45; 95% CI, 0.42-0.49; P < .0001) and those younger than 75 years (30.6% vs 55.1%; OR 0.36; 95% CI, 0.33-0.39; P < .0001), although the magnitude of risk reduction differed (Pinteraction < .0001). CONCLUSIONS In this largest cohort of patients with cardiogenic shock complicating acute myocardial infarction, patients managed invasively had significantly lower mortality when compared with those managed conservatively, even in the elderly. Our results emphasize the need for aggressive management in this high-risk subgroup.

Delayed post-operative cardiac tamponade manifesting as cardiogenic shock. J Cardiol Cases 2013; 8:195-197. [PMID: 30534291 PMCID: PMC6277693 DOI: 10.1016/j.jccase.2013.08.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2013] [Revised: 07/04/2013] [Accepted: 08/10/2013] [Indexed: 10/26/2022] Open
Abstract
We describe the case of a 32-year-old woman with a history of cardiac surgery two weeks previously who presented with an upper gastrointestinal bleed. She also had symptoms of syncope and abdominal pain, as well as elevated liver enzymes. She had cool, clammy extremities, bilateral lower extremity edema, and oliguria. An echocardiogram was obtained, which revealed a large posterior pericardial effusion with evidence of tamponade physiology, and an emergent pericardiocentesis was performed with insertion of a drainage catheter, which drained bloody fluid, with subsequent hemodynamic improvement. 7 days after open-heart surgery, a challenging diagnosis given its vague symptoms and signs not classically associated with the condition.>.

[Syncope unit: experience of a center using diagnostic flowcharts for syncope of uncertain etiology after initial assessment]. Rev Port Cardiol 2013; 32:581-91. [PMID: 23827416 DOI: 10.1016/j.repc.2012.10.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2012] [Revised: 10/29/2012] [Accepted: 10/31/2012] [Indexed: 10/26/2022] Open
Abstract
INTRODUCTION AND OBJECTIVES Syncope is a common symptom that leads to 1% of admissions to hospital emergency departments, and is associated with high costs to the health system. The cardiology department of Faro Hospital has had a syncope unit since July 2007. The aim of this study is to analyze its results in terms of etiological diagnosis and treatment of syncope, using diagnostic flowcharts based on European Society of Cardiology (ESC) guidelines. METHODS We conducted a retrospective study of all patients referred to the syncope unit of Faro Hospital between July 2007 and August 2011. We analyzed demographic data, characteristics of syncopal episodes, diagnostic methods, etiology of syncope and treatment. The percentages of syncope of cardiac and uncertain etiology were compared with data from other international syncope units. Statistical analysis was performed using SPSS version 13.0. RESULTS Of the 304 patients referred to the syncope unit for loss of consciousness, 245 (80.7%) had syncope. Most had reflex syncope (52.2%), 20% had cardiac syncope, 15.6% had orthostatic hypotension, and in 12% of cases etiology remained undetermined. The percentages of cardiac and uncertain etiology were similar to data published by other syncope units. CONCLUSIONS The Faro Hospital syncope unit obtained similar results to those published by other international syncope units through application of diagnostic flowcharts for etiological diagnosis of syncope. The flowcharts presented can be of value for the proper application of ESC guidelines on syncope.
