Abstract
PURPOSE OF REVIEW To discuss future research themes and study design in cardiogenic shock. RECENT FINDINGS Cardiogenic shock research faces multiple challenges, hindering progress in understanding and treating this life-threatening condition. Cardiogenic shock's heterogeneous nature poses challenges in patient selection for clinical trials, potentially leading to variability in treatment responses and outcomes. Ethical considerations arise due to the acuity and severity of the condition, posing challenges in obtaining informed consent and conducting randomized controlled trials where time to treatment is pivotal. SUMMARY This review discusses research in this area focusing on the importance of phenotyping patients with cardiogenic shock, based on artificial intelligence, machine learning, and unravel new molecular mechanisms using proteomics and metabolomics. Further, the future research focus in mechanical circulatory support and targeting inflammation is reviewed. Finally, newer trial designs including adaptive platform trials are discussed.

Development and external validation of a dynamic risk score for early prediction of cardiogenic shock in cardiac intensive care units using machine learning. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2024; 13:472-480. [PMID: 38518758 PMCID: PMC11214586 DOI: 10.1093/ehjacc/zuae037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 03/11/2024] [Accepted: 03/19/2024] [Indexed: 03/24/2024]
Abstract
AIMS Myocardial infarction and heart failure are major cardiovascular diseases that affect millions of people in the USA with morbidity and mortality being highest among patients who develop cardiogenic shock. Early recognition of cardiogenic shock allows prompt implementation of treatment measures. Our objective is to develop a new dynamic risk score, called CShock, to improve early detection of cardiogenic shock in the cardiac intensive care unit (ICU). METHODS AND RESULTS We developed and externally validated a deep learning-based risk stratification tool, called CShock, for patients admitted into the cardiac ICU with acute decompensated heart failure and/or myocardial infarction to predict the onset of cardiogenic shock. We prepared a cardiac ICU dataset using the Medical Information Mart for Intensive Care-III database by annotating with physician-adjudicated outcomes. This dataset which consisted of 1500 patients with 204 having cardiogenic/mixed shock was then used to train CShock. The features used to train the model for CShock included patient demographics, cardiac ICU admission diagnoses, routinely measured laboratory values and vital signs, and relevant features manually extracted from echocardiogram and left heart catheterization reports. We externally validated the risk model on the New York University (NYU) Langone Health cardiac ICU database which was also annotated with physician-adjudicated outcomes. The external validation cohort consisted of 131 patients with 25 patients experiencing cardiogenic/mixed shock. CShock achieved an area under the receiver operator characteristic curve (AUROC) of 0.821 (95% CI 0.792-0.850). CShock was externally validated in the more contemporary NYU cohort and achieved an AUROC of 0.800 (95% CI 0.717-0.884), demonstrating its generalizability in other cardiac ICUs. Having an elevated heart rate is most predictive of cardiogenic shock development based on Shapley values. The other top 10 predictors are having an admission diagnosis of myocardial infarction with ST-segment elevation, having an admission diagnosis of acute decompensated heart failure, Braden Scale, Glasgow Coma Scale, blood urea nitrogen, systolic blood pressure, serum chloride, serum sodium, and arterial blood pH. CONCLUSION The novel CShock score has the potential to provide automated detection and early warning for cardiogenic shock and improve the outcomes for millions of patients who suffer from myocardial infarction and heart failure.

In-hospital and long-term outcomes of cardiogenic shock complicating myocardial infarction versus heart failure. Eur J Heart Fail 2024. [PMID: 38855925 DOI: 10.1002/ejhf.3333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 05/20/2024] [Accepted: 05/21/2024] [Indexed: 06/11/2024] Open
Abstract
AIMS This study sought to examine the difference in clinical characteristics, treatment strategy, trends in mortality, and medical costs according to the aetiologies of cardiogenic shock (CS). METHODS AND RESULTS This was a population-based, nationwide, cohort study from the Korean National Health Insurance Service database. All CS adults (≥18 years) were admitted to an intensive care unit from January 2010 to December 2020. The primary outcome was in-hospital mortality. The secondary outcomes were cardiac replacement therapy (left ventricular assisted device implantation or heart transplantation), all-cause mortality, ischaemic stroke, rehospitalization for heart failure (HF) during follow-up, and actual in-hospital medical costs. Among 136 092 individuals with CS, 48 704 (29.7%) cases were due to acute myocardial infarction-related CS (AMI-CS), and the remaining 87 388 (71.3%) were due to HF-CS (ischaemic cardiomyopathy [ICM] vs. non-ICM, 49 504 [56.6%] vs. 37 884 [45.4%]). Patients with HF-CS were older, less likely to be male, and less likely to receive mechanical circulatory support, compared to those with AMI-CS. During the 10-year study period, the in-hospital mortality rate decreased, and actual medical costs tended to increase, regardless of CS aetiology. Compared with AMI-CS, HF-CS was associated with higher risks of in-hospital mortality (40.3% vs. 28.5%; adjusted odds ratio [OR] 1.47, 95% confidence interval [CI] 1.43-1.52), cardiac replacement therapy (adjusted OR 1.65, 95% CI 1.16-2.34), as well as follow-up mortality after successful discharge (19.3% vs. 8.5%; adjusted-hazard ratio 1.54, 95% CI 1.48-1.59). HF-CS had lower medical costs than AMI-CS (adjusted ratio 0.79, 95% CI 0.79-0.80). CONCLUSIONS With medical advances during the past 10 years, the mortality of CS has decreased significantly, but the mortality of HF-CS remains high. The findings highlight the need for effective treatment strategies for patients with HF-CS.

Identifying and mitigating risk of postcardiotomy cardiogenic shock in patients with ischemic and nonischemic cardiomyopathy. J Thorac Cardiovasc Surg 2024:S0022-5223(24)00191-0. [PMID: 38452888 DOI: 10.1016/j.jtcvs.2024.02.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 02/20/2024] [Accepted: 02/28/2024] [Indexed: 03/09/2024]
Abstract
OBJECTIVES To identify preoperative predictors of postcardiotomy cardiogenic shock in patients with ischemic and nonischemic cardiomyopathy and evaluate trajectory of postoperative ventricular function. METHODS From January 2017 to January 2020, 238 patients with ejection fraction <30% (206/238) or 30% to 34% with at least moderately severe mitral regurgitation (32/238) underwent conventional cardiac surgery at Cleveland Clinic, 125 with ischemic and 113 with nonischemic cardiomyopathy. Preoperative ejection fraction was 25 ± 4.5%. The primary outcome was postcardiotomy cardiogenic shock, defined as need for microaxial temporary left ventricular assist device, extracorporeal membrane oxygenation, or vasoactive-inotropic score >25. RandomForestSRC was used to identify its predictors. RESULTS Postcardiotomy cardiogenic shock occurred in 27% (65/238). Pulmonary artery pulsatility index <3.5 and pulmonary capillary wedge pressure >19 mm Hg were the most important factors predictive of postcardiotomy cardiogenic shock in ischemic cardiomyopathy. Cardiac index <2.2 L·min-1 m-2 and pulmonary capillary wedge pressure >21 mm Hg were the most important predictive factors in nonischemic cardiomyopathy. Operative mortality was 1.7%. Ejection fraction at 12 months after surgery increased to 39% (confidence interval, 35-40%) in the ischemic group and 37% (confidence interval, 35-38%) in the nonischemic cardiomyopathy group. CONCLUSIONS Predictors of postcardiotomy cardiogenic shock were different in ischemic and nonischemic cardiomyopathy. Right heart dysfunction, indicated by low pulmonary artery pulsatility index, was the most important predictor in ischemic cardiomyopathy, whereas greater degree of cardiac decompensation was the most important in nonischemic cardiomyopathy. Therefore, preoperative right heart catheterization will help identify patients with low ejection fraction who are at greater risk of postcardiotomy cardiogenic shock.

Abstract
In the setting of out-of-hospital cardiac arrest, therapeutic hypothermia (TH) has been shown to improve clinical outcomes. However, trials showing the advantage of TH did not include patients with cardiogenic shock (CS). We performed a comprehensive literature search for studies that evaluated the efficacy and safety of adjunctive TH compared with the standard of care (SOC) in patients with CS. The primary outcome was the mortality rate (in-hospital, short-, and mid-term). The secondary outcomes were the TH-related complications, duration of Intensive Care Unit (ICU) stay, duration of mechanical ventilation (MV-days), and improvement in cardiac function. Relative risk (RR) or the standardized mean difference (SMD) and corresponding 95% confidence intervals (CIs) were calculated using the random-effects model. A total of 7 clinical studies (3 RCTs included), and 712 patients (341 in the TH group and 371 in the SOC group) were included. As compared with the SOC, TH was not associated with a statistically significant improvement in the in-hospital (RR: 0.73%, 95% CI: 0.51-1.03; p = 0.08), short-term (RR: 0.90%, 95% CI: 0.75-1.06; p = 0.21), or mid-term (RR: 0.93%, 95% CI: 0.78-1.10; p = 0.38) mortality rates. Despite the improvement in the cardiac function in the TH group (SMD: 1.08, 95% CI: 0.02-2.1; p = 0.04), the TH strategy did not significantly shorten the MV days, or the ICU stay (p-values >0.05). Finally, there was a trend toward higher risks for infection, major bleeding, and the need for blood transfusion in the TH group. According to our meta-analysis of published clinical studies, TH is not beneficial in patients with CS and has a marginal safety profile. Larger-scale RCTs are needed to further clarify our results.

Abstract
Objectives The aim of this study was to explore the associations between percutaneous ventricular assist device (pVAD) insertion timing relative to cardiac surgery and patient outcomes. Methods The Nationwide Inpatient Sample was queried for patients undergoing cardiac surgery and pVAD insertion in the same admission from 2016 to 2019. Patients were stratified by timing of pVAD insertion. Preoperative characteristics, postoperative complications, and mortality were compared among groups. Results Overall, 3695 patients underwent cardiac surgery and pVAD insertion during the same hospitalization (pre: 1130, intra: 1690, and post: 875). The distribution of cardiac surgery procedures was similar across groups. Median Elixhauser Comorbidity Index was 13 for pre-, 15 for intra-, and 17 for postoperative pVAD patients (P = .021). Patients who received a postoperative pVAD were associated with increased mortality (pre: 18%, intra: 39%, and post: 54%; P < .01). Increased complication rates were also associated with postoperative pVAD insertion (pre: 61%, intra: 55%, and post: 75%; P < .01). Preoperative pVAD insertion was associated with increase rates of sepsis (pre: 18%, intra: 9.8%, and post: 17%; P = .01) and pneumonia (pre: 38%, intra: 23%, and post: 31%; P < .01). Postoperative pVAD insertion was associated with increased rates of gastrointestinal bleeding (pre: 2.2%, intra: 3.0%, and post: 7.4%; P = .01), renal failure (pre: 10%, intra: 9.2%, and post: 17%; P = .01), and prolonged ventilation (pre: 44%, intra: 41%, and post: 54%; P = .02). Conclusions Postoperative pVAD insertion following cardiac surgery was associated with increased complications and mortality compared with preoperative or intraoperative insertion. Further studies should explore optimal utilization and timing of pVAD insertion in patients undergoing cardiac surgery.

[PMID: 37797547 DOI: 10.1016/j.amjcard.2023.07.149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Accepted: 07/30/2023] [Indexed: 10/07/2023]
Abstract
Prophylactic distal perfusion cannulation (PDPC) is protectively associated with limb ischemia in patients with cardiogenic shock (CS) receiving femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO). However, evidence supporting its benefits beyond limb ischemia reduction is scarce. We aimed to investigate whether PDPC, compared with no-PDPC, is associated with a lower risk of mortality in patients receiving VA-ECMO. From a multicenter registry, we identified 479 patients who underwent VA-ECMO support for refractory CS. The association of PDPC with 30-day mortality was assessed using multiple methods, including instrumental variable analysis, overlap weighting, and propensity score matching. Of the 479 patients, 154 (32.2%) received PDPC. The 30-day mortality rate was 33.1% in the PDPC group and 53.2% in the no-PDPC group. The instrumental variable analysis showed a protective association of PDPC with 30-day mortality (absolute risk difference -16.7%, 95% confidence interval -31.3% to -2.1%; relative risk 0.68, 95% confidence interval 0.40 to 0.96). The findings were consistent in the overlap-weighted analysis (hazard ratio 0.68, 95% confidence interval 0.48 to 0.98) and in the propensity score-matched analysis (hazard ratio 0.67, 95% confidence interval 0.45 to 1.00). There were no significant differences in safety outcomes, including stroke, ECMO site bleeding, gastrointestinal bleeding, and sepsis, between PDPC and no-PDPC. In conclusion, PDPC was associated with a lower risk of mortality at 30 days in patients with CS receiving VA-ECMO. The efficacy and safety of PDPC merit evaluation in future randomized studies. Clinical trial registration: ClinicalTrials.gov; NCT02985008.

The Impact of Sex on Cardiogenic Shock Outcomes Following ST Elevation Myocardial Infarction. J Clin Med 2023; 12:6259.

Abstract
BACKGROUND Cardiogenic shock (CS) remains the leading cause of ST elevation myocardial infarction (STEMI)-related mortality. Contemporary studies have shown no sex-related differences in mortality. METHODS STEMI-CS patients undergoing primary percutaneous coronary intervention (PPCI) were included based on a dedicated prospective STEMI database. We compared sex-specific differences in CS characteristics at baseline, during hospitalization, and in subsequent clinical outcomes. Endpoints included all-cause mortality and major adverse cardiac events (MACE). RESULTS Of 3202 consecutive STEMI patients, 210 (6.5%) had CS, of which 63 (30.0%) were women. Women were older than men (73.2 vs. 65.5% y, p < 0.01), and more had hypertension (68.3 vs. 52.8%, p = 0.019) and diabetes (38.7 vs. 24.8%, p = 0.047). Fewer were smokers (13.3 vs. 41.2%, p < 0.01), had previous PCI (9.1 vs. 22.3% p = 0.016), or required IABP (35.3 vs. 51.1% p = 0.027). Women had higher rates of mortality (53.2 vs. 35.3% in-hospital, p = 0.01; 61.3 vs. 41.9% at 1 month, p = 0.01; and 73.8 vs. 52.6% at 3 years, p = 0.05) and MACE (60.6 vs. 41.6% in-hospital, p = 0.032; 66.1 vs. 45.6% at 1 month, p = 0.007; and 62.9 vs. 80.3% at 3 years, p = 0.015). After multivariate adjustment, female sex remained an independent factor for death (HR-2.42 [95% CI 1.014-5.033], p = 0.042) and MACE (HR-1.91 [95% CI 1.217-3.031], p = 0.01). CONCLUSIONS CS complicating STEMI is associated with greater short- and long-term mortality and MACE in women. Sex-focused measures to improve diagnosis and treatment are mandatory for CS patients.

Complete revascularization is associated with higher mortality in patients with ST-elevation myocardial infarction, multi-vessel disease and shock defined by hyperlactataemia: results from the Harefield Shock Registry incorporating explainable machine learning. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2023; 12:615-623.

Abstract
AIMS Revascularization strategy for patients with ST-elevation myocardial infarction (STEMI) and multi-vessel disease varies according to the patient's cardiogenic shock status, but assessing shock acutely can be difficult. This article examines the link between cardiogenic shock defined solely by a lactate of ≥2 mmol/L and mortality from complete vs. culprit-only revascularization in this cohort. METHODS AND RESULTS Patients presenting with STEMI, multi-vessel disease without severe left main stem stenosis and a lactate ≥2 mmol/L between 2011 and 2021 were included. The primary endpoint was mortality at 30 days by revascularization strategy for shocked patients. Secondary endpoints were mortality at 1 year and over a median follow-up of 30 months. Four hundred and eight patients presented in shock. Mortality in the shock cohort was 27.5% at 30 days. Complete revascularization (CR) was associated with higher mortality at 30 days [odds ratio (OR) 2.1 (1.02-4.2), P = 0.043], 1 year [OR 2.4 (1.2-4.9), P = 0.01], and over 30 months follow-up [hazard ratio (HR) 2.2 (1.4-3.4), P < 0.001] compared with culprit lesion-only percutaneous coronary intervention (CLOP). Mortality was again higher in the CR group after propensity matching (P = 0.018) and inverse probability treatment weighting [HR 2.0 (1.3-3.0), P = 0.001]. Furthermore, explainable machine learning demonstrated that CR was behind only blood gas parameters and creatinine levels in importance for predicting 30-day mortality. CONCLUSION In patients presenting with STEMI and multi-vessel disease in shock defined solely by a lactate of ≥2 mmol/L, CR is associated with higher mortality than CLOP.

Abstract
Objective.A percutaneous left ventricular assist device (PLVAD) can be used as a bridge to heart transplantation or as a temporary support for end-stage heart failure. Transvalvularly placed PLVADs may result in aortic regurgitation due to unstable pump position during fully supported operation, which may diminish the pumping effect of forward flow and predispose to complications. Therefore, accurate characterization of aortic regurgitation is essential for proper modeling of heart-pump interactions and validation of control strategies.Approach.In the present study, an improved aortic valve model was used to analyze the severity of regurgitation produced by different pump position offsets. The link between pump position offset degree and regurgitation is validated in the fixed speed mode, and the influence of pump speed on regurgitation is verified in the variable speed mode, using the mock circulatory loop (MCL) experimental platform.Main results.The greater the pump offset and the more severe the regurgitation, the more carefully the pump speed needs to be managed. To avoid over-pumping, the recommended pump speed in this study should not exceed 30 000 rpm.Significance.The modeling approach provide in this study not only makes it easier to comprehend the impact of regurgitation events on the entire interactive system during mechanical assistance, but it also aids in providing timely alerts and suitable management measures.

Abstract
AIMS Impact of skin mottling has been poorly studied in patients admitted for cardiogenic shock. This study aimed to address this issue and identify determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all etiologies. METHODS AND RESULTS FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October, 2016. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 660 had skin mottling assessed at admission (85.5%) with almost 39% of patients in cardiogenic shock presenting mottling. The need for invasive respiratory support was significantly higher in patients with mottling (50.2% vs. 30.1%, p < 0.001) and likewise for the need for renal replacement therapy (19.9% vs. 12.4%, p = 0.09). However, the need for mechanical circulatory support was similar in both groups. Patients with mottling at admission presented a higher length of stay (19 vs. 16 days, p = 0.033), a higher 30-day mortality rate (31% vs. 23.3%, p = 0.031), and also showed significantly higher mortality at 1-year (54% vs. 42%, p = 0.003). The subgroup of patients in whom mottling appeared during the first 24 h after admission had the worst prognosis at 30 days. CONCLUSION Skin mottling at admission in patients with cardiogenic shock was statistically associated with prolonged length of stay and poor outcomes. As a perfusion-targeted resuscitation parameter, mottling is a simple, clinical-based approach and may thus help to improve and guide immediate goal-directed therapy to improve cardiogenic shock patients' outcomes.

Relationship between the volume of cases and in-hospital mortality in patients with cardiogenic shock receiving short-term mechanical circulatory support. Am Heart J 2023; 261:109-123.

Abstract
BACKGROUND We examined the relationship between annual case volume at each hospital and outcome in cardiogenic shock (CS) patients receiving mechanical circulatory support (MCS) devices. METHODS This cross-sectional study used the Japanese nationwide database to identify patients receiving short-term MCS for CS between April 2012 and March 2020. Of 65,837 patients, 3 subcohorts were created; the intra-aortic balloon pump (IABP) alone (n = 48,643), the extracorporeal membrane oxygenation (ECMO) (n = 16,871), and the Impella cohorts (n = 696). RESULTS The median annual case volume was 13.5 (7.4-22.1) in the IABP alone cohort, 6.4 (3.4-11.0) in the ECMO cohort, and 7.5 (4.0-10.7) in the Impella cohort. The highest quintile for the volume of cases in the IABP alone and ECMO had the lowest in-hospital mortality (IABP alone, 25.1% in quintile 1 vs 15.2% in quintile 5; ECMO, 73.7% in quintile 1 in 67.4% in quintile 5). Adjusted ORs for in-hospital mortality decreased as case volume increased (IABP alone, 0.63 [0.58-0.68] in quintile 5; ECMO, 0.73 [0.65-0.82] in quintile 5, with the lowest quintile as reference) but did not decrease significantly in the Impella (0.90 [0.58-1.39] in tertile 3, with the lowest tertile as reference). In the continuous models with the case volume as a continuous variable, adjusted ORs for in-hospital mortality decreased to 28 IABP cases/year and 12 ECMO cases/year. They did not decrease or became almost flat above that. CONCLUSIONS Higher volumes of IABP and ECMO are associated with a lower mortality. There is an upper limit to the decline. Centralizing patients with refractory CS in a particular hospital might improve patient outcomes in each region.

Abstract
BACKGROUND Cardiogenic shock (CS) is caused by primary cardiac dysfunction and induced by various and heterogeneous diseases (e.g., acute impairment of cardiac performance, or acute or chronic impairment of cardiac performance). MAIN BODY Although a low cardiac index is a common finding in patients with CS, the ventricular preload, pulmonary capillary wedge pressure, central venous pressure, and systemic vascular resistance might vary between patients. Organ dysfunction has traditionally been attributed to the hypoperfusion of the organ due to either progressive impairment of the cardiac output or intravascular volume depletion secondary to CS. However, research attention has recently shifted from this cardiac output ("forward failure") to venous congestion ("backward failure") as the most important hemodynamic determinant. Both hypoperfusion and/or venous congestion by CS could lead to injury, impairment, and failure of target organs (i.e., heart, lungs, kidney, liver, intestines, brain); these effects are associated with an increased mortality rate. Treatment strategies for the prevention, reduction, and reversal of organ injury are warranted to improve morbidity in these patients. The present review summarizes recent data regarding organ dysfunction, injury, and failure. CONCLUSIONS Early identification and treatment of organ dysfunction, along with hemodynamic stabilization, are key components of the management of patients with CS.

[PMID: 36724180 DOI: 10.1016/j.jchf.2022.11.005] [Citation(s) in RCA: 24] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 10/25/2022] [Accepted: 11/03/2022] [Indexed: 01/13/2023]
Abstract
BACKGROUND It is currently unclear if active left ventricular (LV) unloading should be used as a primary treatment strategy or as a bailout in patients with cardiogenic shock (CS) treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO). OBJECTIVES This study sought to evaluate the association between timing of active LV unloading and implantation of VA-ECMO with outcomes of patients with CS. METHODS Data from 421 patients with CS treated with VA-ECMO and active LV unloading at 18 tertiary care centers in 4 countries were analyzed. Patients were stratified by timing of device implantation in early vs delayed active LV unloading (defined by implantation before up to 2 hours after VA-ECMO). Adjusted Cox and logistic regression models were fitted to evaluate the association between early active LV unloading and 30-day mortality as well as successful weaning from ventilation. RESULTS Overall, 310 (73.6%) patients with CS were treated with early active LV unloading. Early active LV unloading was associated with a lower 30-day mortality risk (HR: 0.64; 95% CI: 0.46-0.88) and a higher likelihood of successful weaning from ventilation (OR: 2.17; 95% CI: 1.19-3.93) but not with more complications. Importantly, the relative mortality risk increased and the likelihood of successful weaning from ventilation decreased almost proportionally with the time interval between VA-ECMO implantation and (delayed) initiation of active LV unloading. CONCLUSIONS This exploratory study lends support to the use of early active LV unloading in CS patients on VA-ECMO, although the findings need to be validated in a randomized controlled trial.

Peripherally inserted concomitant surgical right and left ventricular support, the Propella, is associated with low rates of limb ischemia, with mortality comparable with peripheral venoarterial extracorporeal membrane oxygenation. Surgery 2023; 173:855-863. [PMID: 36435648 DOI: 10.1016/j.surg.2022.10.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 10/02/2022] [Accepted: 10/04/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Mechanical circulatory support effectively treats adult cardiogenic shock. Whereas cardiogenic shock confers high mortality, acute limb ischemia is a known complication of mechanical circulatory support that confers significant morbidity. We compared our novel approach to peripheral mechanical circulatory support with a conventional femoral approach, with a focus on the incidence of acute limb ischemia. METHODS This was a retrospective cohort study of patients treated with mechanical circulatory support between January 1, 2015 and December 5, 2021 at our institution. Patients receiving any femoral peripheral venoarterial extracorporeal membrane oxygenation were compared with those receiving minimally invasive, peripherally inserted, concomitant right and left ventricular assist devices. These included the Impella 5.0 (Abiomed, Danvers, MA) left ventricular assist device and the ProtekDuo (LivaNova, London, UK) right ventricular assist device used concomitantly (Propella) approach. The primary outcome was incidence of acute limb ischemia. The baseline patient characteristics, hemodynamic data, and post-mechanical circulatory support outcomes were collected. Fisher exact test and Wilcoxon rank sum test was used for the categorical and continuous variables, respectively. Kaplan-Meier curves and log-rank test were used to estimate overall survival probabilities and survival experience, respectively. RESULTS Fifty patients were treated with mechanical circulatory support at our institution for cardiogenic shock, with 13 patients supported with the novel Propella strategy and 37 with peripheral venoarterial extracorporeal membrane oxygenation. The baseline characteristics, including patient organ function and medical comorbidities, were similar among the groups. Nine patients suffered mortality in ≤48 hours of mechanical circulatory support initiation and were excluded. Twenty patients (69%) suffered acute limb ischemia in the peripheral venoarterial extracorporeal membrane oxygenation group; 0 patients receiving Propella suffered acute limb ischemia (P < .001). The percentages of patients surviving to discharge in peripheral venoarterial extracorporeal membrane oxygenation and Propella groups were 24% and 69%, respectively (P = .007). CONCLUSION Patients treated with the Propella experienced a lower incidence of acute limb ischemia compared with patients treated with peripheral venoarterial extracorporeal membrane oxygenation.

Rescue aortic valvuloplasty for severe aortic stenosis is simple and effective in severely hemodynamically compromised patients presenting to centers without on-site heart surgery or TAVI facilities. Heart Vessels 2023; 38:957-963. [PMID: 36781429 DOI: 10.1007/s00380-023-02243-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Accepted: 01/26/2023] [Indexed: 02/15/2023]
Abstract
Management of high-risk patients with severe aortic stenosis (AS) is a challenging issue. The prognosis of patients with AS presenting with therapy-refractory pulmonary edema (RPE) or cardiogenic shock (CS) remains poor. The purpose of this study was to assess the 30-day mortality of rescue percutaneous balloon aortic valvuloplasty (PBAV) in AS patients presenting with RPE or CS in a community-based hospital without on-site heart surgery. From January 2016 to February 2019, we identified consecutively admitted patients with CS or RPE related to severe AS who underwent emergent PBAV. The primary end point was 30-day mortality. Secondary end points included procedural adverse events according to the Valve Academic Research Consortium (VARC)-2 criteria and predictive factors of the primary end point. We identified 51 patients with either CS (n = 22) or RPE (n = 29). All PBAV procedures were successful with a significant reduction in peak-to-peak gradient (median, [IQR] from 40 [27] mmHg to 15 [20] mmHg, p < 0.001). No procedural deaths occurred, while adverse events included stroke (4%), minor vascular complications (6%), minor (4%) and major bleedings (4%), and no life-threatening bleeding. Overall, 15 deaths (29%) were noted at 30 days after PBAV, while 53% of the surviving patients were successfully bridged to transcatheter aortic valve implantation (TAVI). 30-day mortality was significantly higher in the CS group compared to the RPE (n = 10 (45%) vs n = 5 (7%), p = 0.029), and was significantly associated with the presence of acute kidney injury (OR 9.09, 95% CI 2.13-38.77, p = 0.003) and elevated pulmonary artery systolic pressure (OR 1.06, 95% CI 1.0-1.12, p = 0.047). Rescue PBAV in patients with severe AS presenting with RPE or CS is a feasible and effective therapeutic option, even in a community-based hospital without on-site heart surgery. Rescue PBAV resulted in 30-day survival of more than 70%, with more than half of the surviving patients having been successfully bridged to TAVI.

Abstract
Background Temporary mechanical circulatory support (MCS) is often used in patients with cardiogenic shock (CS), and the type of MCS may vary by cause of CS. Objectives This study sought to describe the causes of CS in patients receiving temporary MCS, the types of MCS used, and associated mortality. Methods This study used a nationwide Japanese database to identify patients receiving temporary MCS for CS between April 1, 2012, and March 31, 2020. Results Of 65,837 patients, the cause of CS was acute myocardial infarction (AMI) in 77.4%, heart failure (HF) in 10.9%, valvular disease in 2.7%, fulminant myocarditis (FM) in 2.5%, arrhythmia in 4.5%, and pulmonary embolism (PE) in 2.0% of cases. The most commonly used MCS was an intra-aortic balloon pump alone in AMI (79.2%) and in HF (79.0%) and in valvular disease (66.0%), extracorporeal membrane oxygenation with intra-aortic balloon pump in FM (56.2%) and arrhythmia (43.3%), and extracorporeal membrane oxygenation alone in PE (71.5%). Overall in-hospital mortality was 32.4%; 30.0% in AMI, 32.6% in HF, 33.1% in valvular disease, 34.2% in FM, 60.9% in arrhythmia, and 59.2% in PE. Overall in-hospital mortality increased from 30.4% in 2012 to 34.1% in 2019. After adjustment, valvular disease, FM, and PE had lower in-hospital mortality than AMI: valvular disease, OR: 0.56 (95% CI: 0.50-0.64); FM: OR: 0.58 (95% CI: 0.52-0.66); PE: OR: 0.49 (95% CI: 0.43-0.56); whereas HF had similar in-hospital mortality (OR: 0.99; 95% CI: 0.92-1.05) and arrhythmia had higher in-hospital mortality (OR: 1.14; 95% CI: 1.04-1.26). Conclusions In a Japanese national registry of patients with CS, different causes of CS were associated with different types of MCS and differences in survival.

Abstract
Background: Patients supported on mechanical circulatory support devices experience vasodilatory hypotension due to high surface area exposure to nonbiological and non-endothelialized surfaces. Angiotensin II has been studied in general settings of vasodilatory shock, however concerns exist regarding the use of this vasopressor in patients with pre-existing cardiac failure. The objective of this study was to assess the systemic and central hemodynamic effects of angiotensin II in patients with primary cardiac or respiratory failure requiring treatment with mechanical circulatory support devices. Methods: Multicenter retrospective observational study of adults supported on a mechanical circulatory support device who received angiotensin II for vasodilatory shock. The primary outcome was the intraindividual change from baseline in mean arterial pressure (MAP) and vasopressor dosage after angiotensin II. Results: Fifty patients were included with mechanical circulatory devices that were primarily used for cardiac failure (n = 41) or respiratory failure (n = 9). At angiotensin II initiation, the norepinephrine equivalent vasopressor dosage was 0.44 (0.34, 0.64) and 0.47 (0.33, 0.73) mcg/kg/min in the cardiac and respiratory groups, respectively. In the cardiac group, MAP increased from 60 to 70 mmHg (intraindividual P < .001) in the 1 h after angiotensin II initiation and the vasopressor dosage declined by 0.04 mcg/kg/min (intraindividual P < .001). By 12 h, the vasopressor dosage declined by 0.16 mcg/kg/min ( P = .001). There were no significant changes in cardiac index or mean pulmonary artery pressure throughout the 12 h following angiotensin II. In the respiratory group, similar but nonsignificant effects at 1 h on MAP (61-81 mmHg, P = .26) and vasopressor dosage (decline by 0.13 mcg/kg/min, P = .06) were observed. Conclusions: In patients requiring mechanical circulatory support for cardiac failure, angiotensin II produced beneficial systemic hemodynamic effects without negatively impacting cardiac function or pulmonary pressures. The systemic hemodynamic effects in those with respiratory failure were nonsignificant due to limited sample size.

Abstract
BACKGROUND Acute myocardial infarction (AMI) is a serious and fatal heart disease with one of the highest mortality rates in the world. In some countries, percutaneous coronary intervention (PCI) is the preferred reperfusion strategy after AMI, but it cannot achieve safe and effective treatment of AMI after PCI remains a challenging clinical problem. The potential of oral Chinese patent medicines to treat AMI after PCI has been demonstrated, but which type of oral Chinese patent medicines may be preferred remains controversial. The aim of this network meta-analysis was to investigate the efficacy and safety of multiple oral Chinese patent medicines in the treatment of AMI after PCI. METHODS We will conduct a literature search from China National Knowledge Infrastructure, formerly Chinese Biomedical Database (SinoMed), Wanfang Data, Chongqing VIP, PubMed, Embase, Web of Science and Cochrane Library (The Cochrane Database of Systematic Reviews) from their inception until to November 1, 2022, with language restricted to Chinese and English. Then, the study selection process will follow the Preferred Reporting Items for Meta-Analyses guideline, and the quality assessment will be conducted with Cochrane Collaboration's tool. Pairwise and network meta-analysis will be conducted using the WinBUGS V.1.4.3.37 and STATA V.13. Additionally, sensitivity analysis, subgroup analysis, quality assessment, Small-study effects and publication bias will be performed. ETHICS AND DISSEMINATION This work is based on published research and therefore does not require ethical approval. This review will be published in peer-reviewed journals.

Influence of Venoarterial Extracorporeal Membrane Oxygenation Integrated Hemoadsorption on the Early Reversal of Multiorgan and Microcirculatory Dysfunction and Outcome of Refractory Cardiogenic Shock. J Clin Med 2022; 11:jcm11216517. [PMID: 36362744 PMCID: PMC9657372 DOI: 10.3390/jcm11216517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/25/2022] [Accepted: 10/29/2022] [Indexed: 11/06/2022] Open
Abstract
Background: The purpose of this investigation was to evaluate the impact of venoarterial extracorporeal membrane oxygenation (VA−ECMO) integrated hemoadsorption on the reversal of multiorgan and microcirculatory dysfunction, and early mortality of refractory cardiogenic shock patients. Methods: Propensity score−matched cohort study of 29 pairs of patients. Subjects received either VA−ECMO supplemented with hemoadsorption or standard VA−ECMO management. Results: There was a lower mean sequential organ failure assessment score (p = 0.04), lactate concentration (p = 0.015), P(v−a)CO2 gap (p < 0.001), vasoactive inotropic score (p = 0.007), and reduced delta C−reactive protein level (p = 0.005) in the hemoadsorption compared to control groups after 72 h. In−hospital mortality was similar to the predictions in the control group (62.1%) and was much lower than the predicted value in the hemoadsorption group (44.8%). There were less ECMO-associated bleeding complications in the hemoadsorption group compared to controls (p = 0.049). Overall, 90-day survival was better in the hemoadsorption group than in controls without statistical significance. Conclusion: VA−ECMO integrated hemoadsorption treatment was associated with accelerated recovery of multiorgan and microcirculatory dysfunction, mitigated inflammatory response, less bleeding complications, and lower risk for early mortality in comparison with controls.

Abstract
Sophisticated cancer treatments, cardiovascular risk factors, and aging trigger acute cardiovascular diseases in an increasing number of cancer patients. Among acute cardiovascular diseases, cancer treatment, as well as the cancer disease itself, may induce a cardiogenic shock. Although increasing, these cardiogenic shocks are still relatively limited, and their management is a matter of debate in cancer patients. Etiologies that cause cardiogenic shock are slightly different from those of non-cancer patients, and management has some specific features always requiring a multidisciplinary approach. Recent guidelines and extensive data from the scientific literature can provide useful guidance for the management of these critical patients. Even if no etiologic therapy is available, maximal intensive supportive measures can often be justified, as most of these cardiogenic shocks are potentially reversible. In this review, we address the major etiologies that can lead to cardiogenic shock in cancer patients and discuss issues related to its management.

Abstract
There is a lack of data on contemporary trends in the use and outcomes of Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) for cardiogenic shock (CS) at a national level. Patients with CS admitted during January 1st, 2002-December 31, 2018, were identified from the United States National Inpatient Sample. Among all patients admitted with CS, those who received VA-ECMO were identified. We report the trends in use and outcomes in terms of mortality, exit strategies and complications among all patients who received VA ECMO for CS. Among a total of approximately 1.6 million patients admitted with CS during the period from January 1st, 2002 to December 31, 2018; 25, 621(1.5 %) received VA-ECMO. There has been a 23-fold increase in the use of VA-ECMO over the study period, from 0.1 % in 2002 to 3 % in 2018, with a simultaneous decreasing trend of in hospital mortality from 77 % in 2002 to 50 % in 2018. Only approximately 15 % of VA-ECMO patients are discharged home with most survivors discharged to a skilled nursing facility or short-term rehabilitation. Moreover, only a minor proportion of patients on VA ECMO are bridged to heart replacement therapy with durable LVAD (6 %) or cardiac transplantation (2.5 %). In conclusion, the use of VA-ECMO in CS has increased 23-fold from January 2002 to December 2018 with a concomitant decrease in mortality from 77 % in 2002 to 50 % in 2018, only a minority of patients on VA-ECMO for CS are bridged to durable LVAD or cardiac transplantation.

Abstract
Heart failure (HF) is a chronic, progressive, and increasingly prevalent syndrome characterized by stepwise declines in health status and residual lifespan. Despite significant advancements in both pharmacologic and nonpharmacologic management approaches for chronic HF, the burden of HF hospitalization-whether attributable to new-onset (de novo) HF or worsening of established HF-remains high and contributes to excess HF-related morbidity, mortality, and healthcare expenditures. Owing to a paucity of evidence to guide tailored interventions in this heterogeneous group, management of acute HF events remains largely subject to clinician discretion, relying principally on alleviation of clinical congestion, as-needed correction of hemodynamic perturbations, and concomitant reversal of underlying trigger(s). Following acute stabilization, the subsequent phase of care primarily involves interventions known to improve long-term outcomes and rehospitalization risk, including initiation and optimization of disease-modifying pharmacotherapy, targeted use of adjunctive therapies, and attention to contributing comorbid conditions. However, even with current standards of care many patients experience recurrent HF hospitalization, or after admission incur worsening clinical trajectories. These patterns highlight a persistent unmet need for evidence-based approaches to inform in-hospital HF care and call for renewed focus on urgent implementation of interventions capable of ameliorating risk of worsening HF. In this review, we discuss key contemporary and emerging therapeutic strategies for patients hospitalized with de novo or worsening HF.

Abstract
Abstract
Background
Data on the clinical characteristics, electrocardiogram (ECG) findings and outcomes of patients with acute myocardial infarction (AMI) due to total unprotected left main (ULM) artery occlusion is limited.
Methods
Between 2009 and 2021, 44 patients with AMI due to total ULM occlusion underwent primary percutaneous coronary intervention (PCI) at our institution. The ECG, collateral circulation, clinical and procedural characteristics, and in-hospital mortality were retrospectively evaluated.
Results
Twenty five patients presented with shock and 18 patients had in-hospital mortality. Nineteen patients presented with ST-segment elevation myocardial infarction (STEMI), while 25 presented with non-ST-segment elevation myocardial infarction (NSTEMI). ST-segment elevation (STE) in I and STEMI were associated with the absence of collateral circulation, while STE in aVR was associated with its presence. In the NSTEMI group, patients with STE in both aVR and aVL showed more collateral filling of the left anterior descending coronary artery (LAD) territory, while patients with STE in aVR showed more collateral filling of the LAD and the left circumflex artery territory. Compared with total ULM occlusion, patients with partial ULM obstruction presented with more STE in aVR, less STE in aVR and aVL, and less STEMI. Shock, post-PCI TIMI 0–2 flow, non-STE in aVR, STEMI, and STE in I predicted in-hospital mortality. STEMI and the absence of collateral flow were significantly associated with shock.
Conclusions
STE in the precordial leads predicted the absence of collateral circulation while STE in aVR and STE in both aVR and aVL predicted different collateral filling territories in ULM occlusion. STE in I, non-STE in aVR, and STEMI predicted in-hospital mortality in these patients.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a vital mechanical circulatory support modality capable of restoring perfusion for the patient in circulatory failure. Despite increasing adoption of ECMO, there is incomplete understanding of its effects on systemic hemodynamics and how the vasculature responds to varying levels of continuous retrograde perfusion. To gain further insight into the complex ECMO:failing heart circulation, computational fluid dynamics simulations focused on perfusion distribution and hemodynamic flow patterns were conducted using a patient-derived aorta geometry. Three case scenarios were simulated: (1) healthy control; (2) 90% ECMO-derived perfusion to model profound heart failure; and, (3) 50% ECMO-derived perfusion to model the recovering heart. Fluid-structure interface simulations were performed to quantify systemic pressure and vascular deformation throughout the aorta over the cardiac cycle. ECMO support alters pressure distribution while decreasing shear stress. Insights derived from computational modeling may lead to better understanding of ECMO support and improved patient outcomes.

Abstract
BACKGROUND Cardiogenic shock has a high mortality on optimal therapy. Adrenomedullin is released during cardiogenic shock and is involved in its pathophysiological processes. This study assessed treatment with the humanised, monoclonal, non-neutralising, adrenomedullin antibody adrecizumab, increasing circulating concentrations of adrenomedullin in cardiogenic shock. METHODS In this investigator-initiated, placebo-controlled, double-blind, multicentre, randomised trial (ACCOST-HH), patients were recruited from four university hospitals in Germany. Patients were eligible if they were 18 years old or older and hospitalised for cardiogenic shock within the last 48 h. Exclusion criteria were resuscitation for longer than 60 min and cardiogenic shock due to sustained ventricular tachycardia or bradycardia. Adult patients in cardiogenic shock were randomly assigned (1:1) to intravenous adrecizumab (8 mg/kg bodyweight) or placebo using an internet-based software. A block randomisation procedure was applied with stratification by age (older vs younger than 65 years), sex (male vs female), and type of underlying cardiogenic shock (acute myocardial infarction vs other entities). Investigators, patients, and medical staff involved in patient care were masked to group assignment. The primary endpoint was number of days up to day 30 without the need for cardiovascular organ support, defined as vasopressor therapy, inotropes, or mechanical circulatory support (or both) assessed in the intention-to-treat population. Safety outcomes included therapy-emergent serious adverse events, severe adverse events, adverse events, suspected unexpected serious adverse reactions, study drug-related mortality, and total mortality. The trial was registered at ClinicalTrials.gov, NCT03989531, and EudraCT, 2018-002824-17, and is now complete. FINDINGS Between April 5, 2019, and Jan 13, 2021, 150 patients were enrolled: 77 (51%) were randomly assigned to adrecizumab and 73 (49%) to placebo. All patients received the allocated treatment. The number of days without the need for cardiovascular organ support was not different between patients receiving adrecizumab or placebo (12·37 days [95% CI 9·80-14·94] vs 14·05 [11·41-16·69]; adjusted mean difference -1·69 days [-5·37 to 2·00]; p=0·37). Serious adverse events occurred in 59 patients receiving adrecizumab and in 57 receiving placebo (odds ratio 0·92 [95% CI 0·43-1·98]; p=0·83). Mortality was not different between groups at 30 days (hazard ratio 0·99 [95% CI 0·60-1·65]; p=0·98) or 90 days (1·10 [0·68-1·77]; p=0·71). INTERPRETATION Adrecizumab was well tolerated in patients with cardiogenic shock but did not reduce the need for cardiovascular organ support or improve survival at days 30 and 90.

Abstract
This is a focused review looking at the pharmacological support in cardiogenic shock. There are a plethora of data evaluating vasopressors and inotropes in septic shock, but the data are limited for cardiogenic shock. This review article describes in detail the pathophysiology of cardiogenic shock, the mechanism of action of different vasopressors and inotropes emphasizing their indications and potential side effects. This review article incorporates the currently used specific risk-prediction models in cardiogenic shock as well as integrates data from many trials on the use of vasopressors and inotropes. Lastly, this review seeks to discuss the future direction for vasoactive medications in cardiogenic shock.

Comput Biol Med 2022; 141:105178. [PMID: 34995875 PMCID: PMC10600951 DOI: 10.1016/j.compbiomed.2021.105178] [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: 08/13/2021] [Revised: 12/23/2021] [Accepted: 12/24/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) via femoral cannulation is a vital intervention capable of rapidly restoring perfusion for patients in shock. Despite increasing use to provide circulatory support, its hemodynamic effects are poorly understood and the impact of patient-specific anatomical variation on perfusion is unknown. This study investigates the complex failing heart-mechanical circulatory support circulation and analyzes the effect of patient-specific vascular anatomical variations on hemodynamics and end-organ perfusion. METHODS Patient-specific vascular geometries were constructed from segmenting clinical computerized tomography angiography images and quantitatively compared using tortuosity, curvature, torsion, and lumen diameter. Computational fluid dynamic simulations were performed on a subset of geometries selected to represent a range of anatomical variation. Heart failure severity was modeled by varying the relative fraction of total flow provided by the heart and the extracorporeal circuit. A 3-element lumped parameter model was applied to accurately and dynamically model distal perfusion boundary conditions. Hemodynamic parameters and end-organ perfusion were analyzed and compared to assess the effect of anatomical variation. RESULTS Pulsatile antegrade cardiac perfusion and ECMO retrograde perfusion collide in the aorta to form a dynamic watershed region. The size, position, and variation of this region over the cardiac cycle is substantially altered by patient anatomical region. Increased vascular tortuosity reduces the proximal extent of flow from circulatory support and decreases the size of the watershed region. CONCLUSIONS Patient vascular anatomy is a key determinant of the ECMO-failing heart circulation that alters the location and extent of the watershed region and affects the tissues at risk for differential hypoxia and circuit-derived thromboemboli for a given level of support.

Intensive Care Med Exp 2021; 9:62.

Abstract
Background Acute heart failure and cardiogenic shock remain highly morbid conditions despite prompt medical therapy in critical care settings. Mechanical circulatory support (MCS) is a promising therapy for these patients, yet remains managed with open-loop control. Continuous measure of cardiac function would support and optimize MCS deployment and weaning. The nature of indwelling MCS provides a platform for attaining this information. This study investigates how hysteresis modeling derived from MCS device signals can be used to assess contractility changes to provide continuous indication of changing cardiac state. Load-dependent MCS devices vary their operation with cardiac state to yield a device–heart hysteretic interaction. Predicting and examining this hysteric relation provides insight into cardiac state and can be separated by cardiac cycle phases. Here, we demonstrate this by predicting hysteresis and using the systolic portion of the hysteresis loop to estimate changes in native contractility. This study quantified this measurement as the enclosed area of the systolic portion of the hysteresis loop and correlated it with other widely accepted contractility metrics in animal studies (n = 4) using acute interventions that alter inotropy, including a heart failure model. Clinical validation was performed in patients (n = 8) undergoing Impella support. Results Hysteresis is well estimated from device signals alone (r = 0.92, limits of agreement: − 0.18 to 0.18). Quantified systolic area was well correlated in animal studies with end-systolic pressure–volume relationship (r = 0.84), preload recruitable stroke work index (r = 0.77), and maximum slope of left ventricular pressure (dP/dtmax) (r = 0.95) across a range of inotropic conditions. Comparable results were seen in patients with dP/dtmax (r = 0.88). Diagnostic capability from ROC analysis yielded AUC measurements of 0.92 and 0.90 in animal and patients, respectively. Conclusions Mechanical circulatory support hysteretic behavior can be well modeled using device signals and used to estimate contractility changes. Contractility estimate is correlated with other accepted metrics, captures temporal trends that elucidate changing cardiac state, and is able to accurately indicate changes in inotropy. Inherently available during MCS deployment, this measure will guide titration and inform need for further intervention.

CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 39:28-35.

Abstract
BACKGROUND Left ventricular unloading with Impella may improve survival outcomes in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). However, the optimal timing to initiate left ventricular unloading has yet to be established. Therefore, we conducted a systematic review and meta-analysis to compare survival in patients with AMI-CS who were supported with Impella prior to PCI (pre-PCI) to those in whom support was initiated following PCI (post-PCI). METHODS All studies that evaluated the impact of pre-PCI versus post-PCI Impella placement in patients with AMI-CS were included. Primary endpoints included in-hospital, 30-day, and 6-month survival rates. RESULTS We identified five observational studies comparing outcomes in 432 patients with AMI-CS, of which 173 patients were treated with Impella pre-PCI and 259 patients post-PCI. Patients in the pre-PCI group had lower in-hospital mortality compared to patients in the post-PCI group (RR 0.62, 95% CI: 0.50-0.76, I2 = 0%). The lower mortality rate in the pre-PCI group remained evident at 30 days (HR 0.60, 95% CI: 0.47-0.78, I2 = 0%) and at 6 months (HR 0.66, 95% CI: 0.44-0.97, I2 = 0%). There was no difference in the risk of adverse events including reinfarction, stroke, major bleeding, acute ischemic limb, access site bleeding, and hemolysis. CONCLUSIONS In this meta-analysis of studies evaluating survival among AMI-CS patients with left ventricular unloading initiated pre- versus post-PCI, Impella placement prior to PCI was associated with improved survival.

Abstract
Background There is increasing utilization of cardiogenic shock treatment algorithms. The cornerstone of these algorithms is the use of invasive hemodynamic monitoring (IHM). We sought to compare the in‐hospital outcomes in patients who received IHM versus no IHM in a real‐world contemporary database. Methods and Results Patients with cardiogenic shock admitted during October 1, 2015 to December 31, 2018, were identified from the National Inpatient Sample. Among this group, we compared the outcomes among patients who received IHM versus no IHM. The primary end point was in‐hospital mortality. Secondary end points included vascular complications, major bleeding, need for renal replacement therapy, length of stay, cost of hospitalization, and rate of utilization of left ventricular assist devices and heart transplantation. Propensity score matching was used for covariate adjustment. A total of 394 635 (IHM=62 565; no IHM=332 070) patients were included. After propensity score matching, 2 well‐matched groups were compared (IHM=62 220; no IHM=62 220). The IHM group had lower in‐hospital mortality (24.1% versus 30.6%, P<0.01), higher percentages of left ventricular assist devices (4.4% versus 1.3%, P<0.01) and heart transplantation (1.3% versus 0.7%, P<0.01) utilization, longer length of hospitalization and higher costs. There was no difference between the 2 groups in terms of vascular complications, major bleeding, and the need for renal replacement therapy. Conclusions Among patients with cardiogenic shock, the use of IHM is associated with a reduction in in‐hospital mortality and increased utilization of advanced heart failure therapies. Due to the observational nature of the current study, the results should be considered hypothesis‐generating, and future prospective studies confirming these findings are needed.

Abstract
Aims: Unclear neurological outcome often precludes severely compromised patients after out-of-hospital cardiac arrest (OHCA) from mechanical circulatory support (MCS), while it may be considered as rescue therapy for patients with refractory cardiogenic shock (rCS) in the absence of OHCA. This analysis sought to investigate the role of left ventricular (LV) unloading in patients with rCS related to acute myocardial infarction (AMI) after OHCA. Methods: Of 273 consecutive patients receiving microaxial pumps in the Hannover Cardiac Unloading Registry between January 2013 and August 2018, 47 presented with AMI-rCS following successful resuscitation. Subsequently, the patients were compared by propensity score matching to patients with OHCA AMI-rCS without MCS. The patient data for OHCA without LV unloading was available from 280 patients of the Hannover Cooling Registry for the same time period. Furthermore, the patients with OHCA without rCS were compared to the patients with OHCA AMI-rCS and LV unloading. Results: In total, 15 OHCA AMI-rCS patients without MCS were matched to patients with AMI-rCS and Impella. Patients without LV support had a higher proportion of a cardiac cause of death (n = 7 vs. n = 3; p = 0.024). LV unloading with Impella counteract rCS status and was associated with a preferable 30-day survival (66.7 vs. 20%, p = 0.01) and a favorable neurological outcome after 30 days (Cerebral Performance Category ≤2, 47 vs. 27%). Impella support is associated with a higher 30-day survival (odds ratio, 2.67; 95% confidence interval, 1.02-13.66). Conclusion: In patients after OHCA with AMI-rCS, Impella support incorporated in a strict standardized treatment algorithm results in a preferable 30-day survival and counteracts severe rCS status.

Abstract
Background There is a lack of contemporary data on cardiogenic shock (CS) in-hospital mortality trends. Methods and Results Patients with CS admitted January 1, 2004 to December 31, 2018, were identified from the US National Inpatient Sample. We reported the crude and adjusted trends of in-hospital mortality among the overall population and selected subgroups. Among a total of 563 949 644 hospitalizations during the period from January 1, 2004, to December 30, 2018, 1 254 358 (0.2%) were attributed to CS. There has been a steady increase in hospitalizations attributed to CS from 122 per 100 000 hospitalizations in 2004 to 408 per 100 000 hospitalizations in 2018 (Ptrend<0.001). This was associated with a steady decline in the adjusted trends of in-hospital mortality during the study period in the overall population (from 49% in 2004 to 37% in 2018; Ptrend<0.001), among patients with acute myocardial infarction CS (from 43% in 2004 to 34% in 2018; Ptrend<0.001), and among patients with non-acute myocardial infarction CS (from 52% in 2004 to 37% in 2018; Ptrend<0.001). Consistent trends of reduced mortality were seen among women, men, different racial/ethnic groups, different US regions, and different hospital sizes, regardless of the hospital teaching status. Conclusions Hospitalizations attributed to CS have tripled in the period from January 2004 to December 2018. However, there has been a slow decline in CS in-hospital mortality during the studied period. Further studies are necessary to determine if the recent adoption of treatment algorithms in treating patients with CS will further impact in-hospital mortality.

Abstract
This study investigated the potential genes and related pathways in burn-induced myocardial injury. Rat myocardial injury induced by third-degree burn and the histopathological structures, apoptosis, and cardiac injury markers were then identified using hematoxylin & eosin staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining, and enzyme-linked immunosorbent assay. Next, differentially expressed mRNAs were screened through next-generation sequencing (NGS), followed by functional annotation and key gene validation through quantitative reverse transcription-polymerase chain reaction. Subsequently, CD14 was screened out, and small interfering RNAs against CD14 were transfected to H9C2 cells to further verify the role of CD14 in burn-induced injury. The results showed that third-degree burn could markedly damage the structure of myocardial tissue, induce the apoptosis of myocardial cells, and increase the levels of myocardial injury-related markers, suggesting that burns could induce myocardial injury in rats. Besides, NGS data discovered that third-degree burn could result in 416 differentially upregulated mRNAs and 285 differentially downregulated mRNAs in myocardial tissue. It was also disclosed that differentially expressed mRNAs were mainly enriched in the phosphatidylinositol 3-kinase/Akt, mitogen-activated protein kinase (MAPK), and tumor necrosis factor signaling pathways. Furthermore, cell viability was significantly decreased in H9C2 cells treated with 10% rat burn serum. CD14 was significantly differentially expressed and screened out for further studies. Treatment with burn serum can significantly upregulate the phosphorylation level of extracellular signal-regulated kinase, p38, and c-Jun N-terminal kinase and the expression of cleaved caspase-3 and downregulate the expression of Bcl2 when compared with those in negative control of small interfering RNA transfected H9C2 cells, whereas interfering with CD14 expression reversed the effects of burn serum. The study demonstrated that burn serum treatment could activate the MAPK signaling pathway to promote cell apoptosis, and it can be reversed by interfering with the expression of CD14.

Abstract
PURPOSE OF REVIEW We describe the pathophysiology of cardiogenic shock (CS), from the main pathways to the inflammatory mechanisms and the proteomic features. RECENT FINDINGS Although the classical pathophysiological pathways underlying CS, namely reduced organ perfusion due to inadequate cardiac output and peripheral vasoconstriction, have been well-established for a long time, the role of macro-and micro-hemodynamics in the magnitude of the disease and its prognosis has been investigated extensively only over the last few years. Moreover, to complete the complex picture of CS pathophysiology, the study of cytokine cascade, inflammation, and proteomic analysis has been addressed recently. SUMMARY Understanding the pathophysiology of CS is important to treat it optimally.

Abstract
Objective We sought to assess the relative merits of different revascularization strategies in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease complicated by cardiogenic shock or chronic total occlusion (CTO). Background Recent randomized trials and meta-analysis have suggested that multivessel percutaneous coronary intervention (PCI) is associated with better outcomes in patients with STEMI and multivessel coronary artery disease, however, patients complicated by cardiogenic shock or CTO were excluded. Methods Studies that compared multivessel PCI (immediate or staged) with culprit-only PCI in patients with STEMI and multivessel coronary artery disease complicated by cardiogenic shock or CTO were included. Random odd ratio (OR) and 95% confidence interval (CI) were conducted. Results Sixteen studies with 8695 patients complicated by cardiogenic shock and eight studies with 2259 patients complicated by CTO were included. In patients complicated by cardiogenic shock, a strategy of CO-PCI was associated with lower risk for short-term renal failure (OR: 0.75; 95% CI: 0.61–0.93; I2 = 0.0%), with no significant difference in MACE, all-cause mortality, re-infarction, revascularization, cardiac death, heart failure, major bleeding, or stroke compared with an immediate MV-PCI strategy. In patients complicated by CTO, a strategy of CO-PCI was associated with higher risk for long-term MACE (OR: 2.06; 95% CI: 1.39–3.06; I2 = 54.0%), all-cause mortality (OR: 2.89; 95% CI: 2.09–4.00; I2 = 0.0%), cardiac death (OR: 3.12; 95% CI: 2.05–4.75; I2 = 16.8%), heart failure (OR: 1.99; 95% CI: 1.22–3.24; I2 = 0.0%), and stroke (OR: 2.80; 95% CI: 1.04–7.53; I2 = 0.0%) compared with a staged MV-PCI strategy, without any difference in re-infarction, revascularization, or major bleeding. Conclusions For patients with STEMI and multivessel coronary artery disease complicated by cardiogenic shock, an immediate multivessel PCI was not advocated due to a higher risk for short-term renal failure, whereas for patients complicated by CTO, a staged multivessel PCI was advocated due to reduced risks for long-term MACE, all-cause mortality, cardiac death, heart failure, and stroke.

[PMID: 34016408 DOI: 10.1016/j.jcin.2021.03.048] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/23/2021] [Accepted: 03/23/2021] [Indexed: 12/15/2022]
Abstract
OBJECTIVES The aim of this study was to investigate whether earlier extracorporeal membrane oxygenation (ECMO) support is associated with improved clinical outcomes in patients with refractory cardiogenic shock (CS). BACKGROUND The prognosis of patients with refractory CS receiving ECMO remains poor. However, little is known about the association between the timing of ECMO implantation and clinical outcomes in these patients. METHODS From a multicenter registry, 362 patients with refractory CS who underwent ECMO between January 2014 and December 2018 were identified. Participants were classified into 3 groups according to tertiles of shock-to-ECMO time (early, intermediate, and late ECMO). Inverse probability of treatment weighting was conducted to adjust for baseline differences among the groups, followed by a weighted Cox proportional hazards regression analysis to calculate hazard ratios and 95% confidence intervals for 30-day mortality associated with each ECMO time group. RESULTS The overall 30-day mortality rate was 40.9%. The risk for 30-day mortality was lower in the early group than in the late group (hazard ratio: 0.53; 95% confidence interval: 0.28 to 0.99). Early ECMO support was also associated with lower risk for in-hospital mortality, ECMO weaning failure, composite of all-cause mortality or rehospitalization for heart failure at 1 year, all-cause mortality at 1 year, and poor neurological outcome at discharge. However, the incidence of adverse events, including stroke, limb ischemia, ECMO-site bleeding, and gastrointestinal bleeding, did not differ significantly among the groups. CONCLUSIONS Earlier ECMO support was associated with improved clinical outcomes in patients with refractory CS.

Abstract
OBJECTIVES The aim of this study was to compare in-hospital outcomes and long-term mortality of multivessel versus culprit vessel-only percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation myocardial infarction (NSTEMI), multivessel disease (MVD) and cardiogenic shock. BACKGROUND The clinical benefits of complete revascularization in patients with NSTEMI, MVD, and cardiogenic shock remain uncertain. METHODS Among 25,324 patients included in the National Cardiovascular Data Registry CathPCI Registry from July 2009 to March 2018, the rates of in-hospital procedural outcomes were compared between those undergoing multivessel PCI and those undergoing culprit vessel-only PCI after 1:1 propensity score matching. Among patients aged ≥65 years matched to the Centers for Medicare and Medicaid Services database, long-term mortality was compared using proportional hazards analysis. RESULTS Multivessel PCI was performed in 9,791 patients (38.7%), which increased from 32.2% in 2010 to 44.2% in 2017 (p for trend <0.001). After 1:1 propensity matching (n = 7,864 in each group), those undergoing multivessel PCI had a 3.5% (95% confidence interval [CI]: 2.0% to 5.0%) lower absolute rate of in-hospital mortality (30.9% vs. 34.4%; p < 0.001; odds ratio [OR]: 0.85; 95% CI: 0.80 to 0.91), but a higher risk for bleeding (13.2% vs. 10.8%; p < 0.001; OR: 1.26; 95% CI: 1.15 to 1.40) and new requirement for dialysis (5.7% vs. 4.6%; p = 0.001; OR: 1.26; 95% CI: 1.10 to 1.46). Among those surviving to discharge, all-cause mortality was similar through 7 years (conditional hazard ratio: 0.95; 95% CI: 0.87 to 1.03; p = 0.20). CONCLUSIONS Nearly 40% of patients with NSTEMI with MVD and cardiogenic shock underwent multivessel PCI, which was associated with lower in-hospital mortality but greater peri-procedural complications. Among those surviving to discharge, multivessel PCI did not confer additional long-term mortality benefit.

Abstract
Background The number of heart transplantations (HTx) is increasing annually. Due to advances in medical and surgical support, the outcomes of HTx are also improving. Extracorporeal circulatory life support (ECLS) provides patients with decompensated heart failure a chance to undergo HTx. A medical approach involving collaboration among experienced experts in different fields should improve the outcomes and prognosis of ECLS-bridged HTx. Methods From December 2003 to December 2018, 1,465 patients received ECLS at Samsung Medical Center. We excluded patients who had not undergone HTx or underwent repeated transplantations. Patients younger than 18 years were excluded. We also excluded patients who received an implantable durable left ventricular assist device before HTx. In total, 91 patients were included in this study. A multidisciplinary team approach began in March 2013 at our hospital. We divided the patients into 2 groups depending on whether they were treated before or after implementation of the team approach. Results The 30-day mortality rate was significantly higher in the pre-ECLS team group than in the post-ECLS team group (n=5, 18.5% vs. n=2, 3.1%; p=0.023). The 1-year survival rate was better in the post-ECLS team group than in the pre-ECLS team group (n=57, 89.1% vs. n=19, 70.4%; p=0.023). Conclusion We found that implementing a multidisciplinary team approach improved the outcomes of ECLS-bridged HTx. Team-based care should be adapted at HTx centers that perform high-risk HTx.

Abstract
BACKGROUND The suitability of model for end-stage liver disease excluding international normalized ratio (MELD-XI) score to predict the incidence of acute kidney injury (AKI) and in-hospital mortality in adult patients with postcardiotomy cardiogenic shock (PCS) requiring venoarterial extracorporeal membrane oxygenation (VA ECMO) remains uncertain. This study was performed to explore whether the MELD-XI score has the association with the incidence of AKI and in-hospital mortality in these patients. METHODS Adult patients with PCS requiring VA ECMO from January 2012 to December 2017 were enrolled and first classified into AKI group (n = 151) versus no-AKI group (n = 132), then classified into survival group (n = 143) versus no-survival group (n = 140). Multivariate logistic regressions were performed to identify factors independently associated with AKI and mortality. Baseline data were defined as the first measurement available. RESULTS Of 283 patients, the incidence of AKI was 53.36%. The in-hospital mortality rates were 63.58% and 33.33% in patients with and without AKI (p < 0.0001). Baseline MELD-XI score, baseline serum total bilirubin (T-Bil), baseline blood urea nitrogen (BUN), baseline left ventricular ejection fraction (LVEF), sequential organ failure assessment (SOFA) score, and lactate level at ECMO initiation were shown to be associated with the AKI. Vasoactive-inotropic score (VIS) and SOFA score at ECMO initiation as well as renal failure requiring renal replacement therapy (RRT) were shown to be associated with in-hospital mortality. CONCLUSIONS The baseline MELD-XI score, baseline BUN, baseline T-Bil, baseline LVEF, SOFA score and lactate at the initiation of ECMO were associated with AKI. AKI, SOFA score, and VIS at the initiation of ECMO were associated with in-hospital mortality, whereas MELD-XI score was not found to be associated with in-hospital mortality. A specific MELD-XI score as a threshold, as well as its sensitivity and specificity, needs to be confirmed in further studies.

Abstract
Myocarditis is a fatal inflammatory disease of myocardium, diagnosed with clinical and histopathological findings by endomyocardial biopsy (EMB). Myocarditis has a variety of clinical presentations and a dynamic and sometimes rapid process of severity. Echocardiography plays an important role in the management of myocarditis because it has noninvasiveness and portability. Once acute myocarditis is suspected by an echocardiography, pathological information should be required as early as possible. In our cardiovascular center, emergency EMB suspecting myocarditis was performed in 19 cases (1.3%) among consecutive 1469 cases (70.1 ± 12.6 years old, male 67.5%) undergoing emergency coronary angiograms from April 2014 to September 2017. Hematoxylin-eosin stain of the biopsy specimens were prepared with microwave-accelerated histoprocessing within 3-5 hours after EMB for rapid pathological diagnosis of myocarditis. We reviewed the value of emergency echo-EMB combination leading to the early decision making of intensive care, corticosteroids and proper mechanical circulatory support prior to the possible sudden collapse in patients with myocarditis.

Abstract
Background: Enteral nutrition (EN) is recommended within the first 24-48 h for patients with hemodynamic stability, following admission to an intensive care unit (ICU). However, for patients with approximate stable hemodynamics requiring mechanical circulatory support and vasoactive drugs, the application of early EN remains controversial. We sought to evaluate the tolerance of early EN in patients with cardiogenic shock who required vasoactive drugs and mechanical circulatory support after cardiac surgery. Methods: This single-center, prospective observational study included patients with cardiogenic shock, requiring vasoactive drugs and mechanical circulatory support after cardiac surgery, undergoing EN. The primary endpoint was EN tolerance and secondary endpoints were mortality, length of mechanical ventilation, and length of ICU stay. Results: From February 2019 to December 2020, 59 patients were enrolled, of which 25 (42.37%) developed intolerance within 3 days of starting EN. Patients in the EN intolerant group had a longer median length of mechanical ventilation (380 vs. 128 h, p = 0.006), a longer median ICU stay (20 vs. 11.5 days, p = 0.03), and a higher proportion of bloodstream infections (44 vs. 14.71%, p = 0.018). The median EN calorie levels for all patients in the first 3 days of EN were 4.00, 4.13, and 4.28 kcal/kg/day, respectively. Median protein intake levels of EN in the first 3 days were 0.18, 0.17, and 0.17 g/kg/day, respectively. No significant difference was observed in the median dose of vasoactive drugs between the groups (0.035 vs. 0.05 μg/kg/min, p = 0.306). Conclusions: Patients with cardiogenic shock after cardiac surgery had a high proportion of early EN intolerance, and patients with EN intolerance had a worse prognosis, but no significant correlation was identified between EN tolerance and the dose of vasoactive drugs.

Abstract
Cardiogenic shock is a constant challenge for the intensivist when complicating a myocardial infarction, due to the high rate of associated morbidity and mortality, especially in the setting of mechanical complications such as papillary muscle rupture. We present the case of a 49-year-old woman with cardiogenic shock due to acute myocardial infarction (AMI) complicated by severe mitral valve insufficiency due to papillary muscle rupture. She was treated initially by medical optimization, followed by mitral valve replacement and complete surgical revascularization, requiring rescue mechanical circulatory support by extracorporeal membrane oxygenation (ECMO). ECMO proved to be a rescue therapy in a patient with refractory cardiogenic shock after urgent cardiac surgery.

Abstract
Cardiogenic shock occurs when the heart is unable to pump enough blood for the needs of the body. Hypopituitarism is a condition in which the pituitary gland does not produce enough of one or more hormones, and it rarely occurs with thyrotoxicosis. We report a rare case of cardiogenic shock induced by anterior pituitary hypofunction and thyrotoxicosis. A 47-year-old woman was admitted twice to the hospital due to generalized worsening muscle pain for 13 days, and accompanied by a transient loss of consciousness. Cardiogenic shock developed during hospitalization, which improved with active resuscitative measures. Laboratory tests showed thyrotoxicosis. Pituitary magnetic resonance imaging (MRI) and relevant hormone tests confirmed anterior pituitary hypofunction. The patient was given hormone replacement therapy, which stabilized her condition. We believe cardiogenic shock may be a serious complication of hypopituitarism. We recommend establishing an expert system (ES) to facilitate the early diagnosis and treatment of cardiogenic shock, improve the professional skills of primary care physicians, and optimize treatment plans.
