RESUMEN
Cardiogenic shock (CS) is a serious complication of heart attack and constitutes one of its main causes of death. To date, there is no data on its treatment and evolution in Latin America. OBJECTIVES: To know the clinical characteristics, treatment strategies, evolution and in-hospital mortality of CS in Latin America. MATERIALS AND METHODS: This is a prospective, multicenter registry of patients hospitalized with CS in the context of acute coronary syndromes (ACS) with and without ST segment elevation for 24 months. RESULTS: 41 Latin American centers participated incorporating patients during the period between October 2021 and September 2023. 278 patients were included. Age: 66 (59-75) years, 70.1 % men. 74.8 % of the cases correspond to ACS with ST elevation, 14.4 % to ACS without ST elevation, 5.7 % to right ventricular infarction and 5.1 % to mechanical complications. CS was present from admission in 60 % of cases. Revascularization: 81.3 %, inotropic use: 97.8 %, ARM: 52.5 %, Swan Ganz: 17 %, intra-aortic balloon pump: 22.2 %. Overall in-hospital mortality was 52.7 %, with no differences between ACS with or without ST. CONCLUSIONS: Morbidity and mortality is very high despite the high reperfusion used.

BACKGROUND: The intra-aortic balloon pump (IABP) technique plays a crucial role in providing circulatory support for patients experiencing hemodynamic instability. This study aimed to assess the effectiveness and safety of preoperative prophylactic IABP insertion in patients undergoing acute critical coronary artery bypass grafting (CABG). METHODS: A comprehensive search was conducted in PubMed, Cochrane Library, and Embase databases, covering the period from January 1995 to September 2022. RESULTS: The incidence of renal insufficiency, mechanical ventilation exceeding 24 h, and bleeding events in the IABP group did not exhibit significant differences compared to the control group (relative risk [RR] = 0.85, P = 0.26; RR = 0.81, P = 0.08; RR = 0.95, P = 0.87). However, the hospital mortality rate was significantly lower in the IABP group than in the control group (RR = 0.54, P = 0.0007), and the length of ICU stay was shorter in the IABP group (mean difference [MD] = -1.12, P < 0.000001). The IABP group also exhibited a lower incidence of low cardiac output syndrome (LCOS%) compared to the control group (RR = 0.61, P < 0.0001), and a lower incidence of major adverse cardiac and cerebrovascular events (MACCE%) (RR = 0.70, P = 0.001). No significant publication bias was observed in the funnel plot analysis. CONCLUSION: Preoperative prophylactic insertion of IABP is currently considered beneficial in improving outcomes for critically ill patients undergoing CABG. This technique reduces hospital mortality, shortens ICU stays, and lowers the incidence of LCOS% and MACCE%.

BACKGROUND: Cardiogenic shock (CS) is associated with significant morbidity and mortality. Sex differences in the outcomes and management of cardiogenic shock are not well established. The primary objective of this study is to investigate the differences inik cardiogenic shock outcomes between males and females. METHODS: A systematic review and meta-analysis were conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Studies were searched via the MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases from inception to December 2022. RESULTS: The analysis included 24 studies comprising 1,567,660 patients. Compared to females, males with CS had a significantly lower risk of in-hospital all-cause mortality (risk ratio [RR] 0.88, 95 % confidence interval [CI] 0.85-0.90, p < 0.001) and 1-year mortality (RR 0.90, 95 % CI 0.89-0.92, p < 0.001). Males were more likely to undergo percutaneous coronary intervention (RR 1.21, 95 % CI 1.13-1.31, p < 0.0001) and intra-aortic balloon pump placement (RR 1.21, 95 % CI 1.11-1.32, p < 0.0001), with no significant sex differences in the use of extracorporeal membrane oxygenation or Impella. During the index hospitalization, males were at higher risk of arrhythmias (RR 1.18, 95 % CI 1.05-1.34, p = 0.003) and less likely to develop acute kidney injury (RR 0.86, 95 % CI 0.79-0.94, p < 0.001). CONCLUSION: Men have a lower all-cause mortality risk in cardiogenic shock. Addressing disparities in management is crucial for improving CS outcomes, especially for women.

BACKGROUND: Cardiogenic Shock (CS) complicating acute myocardial infarction (AMI) poses a significant mortality risk, suggesting the opportunity to implement effective mechanical circulatory support strategies. The comparative efficacy of Intra-Aortic Balloon Pump (IABP) and Impella in managing CS-AMI remains a subject of investigation. OBJECTIVE: This meta-analysis aims to evaluate the comparative effectiveness of Impella and IABP in managing CS-AMI, exploring mortality and adverse events. METHODS: A systematic search of major databases from inception to November 2023 identified eight studies, comprising 10,628 patients, comparing Impella and IABP in CS-AMI. Retrospective studies (preferably Propensity-matched) and Randomized Clinical Trials (RCTs) were included. RESULTS: Impella use exhibited significantly higher mortality (57% vs. 46%; OR: 1.44, 95% CI: 1.29-1.60; p < 0.001) and major bleeding (30% vs 15%; OR: 2.93, 95% CI: 1.67-5.13; p < 0.001). CONCLUSIONS: In unselected CS-AMI patients, Impella usage is associated with significantly higher mortality and major bleeding.

INTRODUCTION: Despite the growing use of temporary mechanical circulatory support (tMCS), little data exists to inform management and weaning of these devices. METHODS: We performed an online survey among cardiac intensive care unit directors in North America to examine current practices in the management of patients treated with intraaortic balloon pump and Impella. RESULTS: We received responses from 84% of surveyed centers (n=37). Our survey focused on three key aspects of daily management: 1. Hemodynamic monitoring; 2. Hemocompatibility; and 3. Weaning and removal. We found substantial variability surrounding all three areas of care. CONCLUSION: Our findings highlight the need for consensus around practices associated with improved outcomes in patients treated with tMCS.

PURPOSE OF REVIEW: Discussing the rationale and current evidence for left ventricular unloading in cardiogenic shock. RECENT FINDINGS: Microaxial flow pumps (MFP) and intra-aortic balloon pumps (IABP) augment cardiac output while simultaneously unloading the left ventricle (e.g. reducing left ventricular pressure), thereby targeting a key mechanism of cardiogenic shock. A recent randomized trial has shown a mortality reduction with MFP in selected patients with cardiogenic shock, strengthening the rationale for this strategy, although the evidence for the IABP is so far neutral. MFP/IABP can also be used concomitantly with veno-arterial extracorporeal membrane oxygenation (va-ECMO) to alleviate the va-ECMO-related increase in left ventricular afterload, to facilitate weaning and ultimately to improve myocardial recovery and prognosis of affected patients. However, the use of MFP/IABP in this indication solely relies on retrospective data, which need to be interpreted with caution, especially as these strategies are associated with more complications. Currently ongoing randomized trials will help to further clarify the role of left ventricular unloading in patients on va-ECMO. SUMMARY: Left ventricular unloading addresses a key mechanism of cardiogenic shock, with strong evidence to support MFP use in selected patients, but further randomized controlled trials are required to clarify the role of different devices/strategies for the overall shock population.

Right ventricular dysfunction (RVD) continues to be a significant contributor to both mortality and morbidity, posing a significant challenge in the management of patients undergoing evaluation for mechanical circulatory support (MCS). Currently, there is a paucity of data regarding outcomes in this subset of patients. We analyzed the National Inpatient Sample database (NIS) to identify adult hospitalizations who underwent intra-aortic balloon pump (IABP) placement with or without co-existence of RVD. Multivariate logistic regression, and linear regression analyses were used to compare outcomes, and adjust for possible confounders. Out of 126,985 hospitalizations who underwent IABP placement, 1,475 (1.2%) had RVD. Patients with RVD who received an IABP had higher adjusted odds of inpatient mortality (Adjusted odds ratio [aOR]: 2.33, 95% confidence interval [CI]: 1.7-3.2, p<0.001) than those without co-existing RVD. Hospitalized patients who underwent IABP placement with RVD had higher adjusted odds of worse hospitalization outcomes in general. Conducting additional prospective studies and clinical trials with an emphasis on further subcategorization of patients with RVD is crucial for determining optimal management strategies for these patients.

Severe right heart failure, often overlooked and challenging to manage, has prompted a growing interest in innovative approaches to provide functional support. This study uses experimentation in large porcine models to introduce a novel prototype of a pulsatile mechanical circulatory support device and document its effects when deployed as a right ventricular assist device (RVAD). The pulsatile ventricular assist platform (pVAP), featuring a membrane pump driven by an intra-aortic balloon pump console, actively generates pulsatile flow to propel right ventricular blood into the pulmonary artery. This novel prototype demonstrates promising potential in addressing the challenges of right heart failure management. After preliminary in vitro assessments, the pVAP was tested on seven porcine models in a healthy state and after the induction of right ventricular failure. During the procedure, a set of standard ( ie , standard-of-care) hemodynamic measurements was obtained. Additionally, invasive pressure-volume loop analysis was employed to examine left ventricular hemodynamics. Results indicated that activation of the pVAP during right ventricular failure significantly improved systemic hemodynamics and enhanced left ventricular function. This study sheds light on the potential of the pVAP in managing right heart failure.

BACKGROUND: Evidence supporting anticoagulation with unfractionated heparin (UFH) in patients with an intra-aortic balloon pump (IABP) to prevent limb ischaemia remains limited, while bleeding risks remain high. Monitoring heparin in this setting with anti-factor Xa (anti-Xa) is not previously described. OBJECTIVES: The study objective is to describe the incidence of thromboembolic and bleeding events with the use of UFH in patients with an IABP utilising monitoring with both anti-Xa and activated partial thromboplastin time (aPTT). METHODS: This is a retrospective study of adults who received an IABP and UFH for ≥24 hours. Electronic medical records were reviewed for pertinent data. The primary outcome was the incidence of limb ischaemia during IABP. Secondary outcomes included myocardial infarction, thrombus on IABP, or stroke. Exploratory outcomes included any venous thromboembolism and bleeding events. RESULTS: Of 159 patients, 88% received an IABP for cardiogenic shock and median duration of IABP support was 118 hours (interquartile range, 67-196). Limb ischaemia occurred in four of 159 patients (2.5%). Strokes occurred in 3.8% of the cohort, and bleeding events occurred in 33%. Despite anticoagulation use in all patients, 11% experienced a venous thromboembolism, with most identified upon asymptomatic screening with concern for heparin-induced thrombocytopenia. We found no differences in outcomes that occurred with a hybrid anti-Xa and aPTT versus aPTT monitoring alone. CONCLUSIONS: We observed a high rate of thrombotic and bleeding complications with the use of UFH in patients with an IABP. Use of anti-Xa versus aPTT for monitoring was not associated with complications. These data suggest safer anticoagulation strategies are needed in this setting.

This case report describes the exercise program on a hospitalized 54-year-old male patient with cardiogenic shock waiting for a heart transplant assisted by an intra-aortic balloon pump, a temporary mechanical circulatory support device. The temporary mechanical circulatory support device, an intra-aortic balloon pump, was placed in the left subclavian artery, enabling the exercise protocol. Measurements and values from Swan-Ganz catheter, blood sample, brain natriuretic peptide (NT-proBNP), and high-sensitivity C-reactive protein (hs-CRP), as well as the six-minute walk test (6MWT) and venous oxygen saturation (SvO2) were obtained before and after an exercise protocol. The exercise training protocol involved the use of an unloaded bed cycle ergometer once a day, for a maximum of 30 minutes, to the tolerance limit. No adverse events or events related to the dislocation of the intra-aortic balloon pump were observed during the exercise protocol. The exercise program resulted in higher SvO2 levels, with an increased 6MWT with lower Borg dyspnea scores (312 meters vs. 488 meters and five points vs. three points, respectively). After completing the ten-day exercise protocol, the patient underwent a non-complicated heart transplant surgery and a full recovery in the ICU. This study showed that exercise is a feasible option for patients with cardiogenic shock who are using an intra-aortic balloon pump and that it is well-tolerated with no reported adverse events.
O presente relato de caso descreve o programa de exercícios aplicado a um paciente do sexo masculino, de 54 anos, internado com choque cardiogênico, aguardando transplante cardíaco e assistido por balão intra-aórtico, um dispositivo de suporte circulatório mecânico temporário. O dispositivo de suporte circulatório mecânico temporário, um balão intra-aórtico, foi colocado na artéria subclávia esquerda, possibilitando o protocolo de exercícios. Antes e após um protocolo de exercícios, foram obtidos dados a partir de cateter de Swan-Ganz, amostra de sangue, peptídeo natriurético cerebral (NT-proBNP), proteína C reativa de alta sensibilidade (PCR-as), teste de caminhada de seis minutos (TC6min) e medição da saturação venosa de oxigênio (SvO2). O protocolo de treinamento físico envolveu a utilização de um cicloergômetro adaptado ao leito, sem carga, uma vez ao dia, por no máximo 30 minutos, até o limite da tolerância. Não foram observados eventos adversos tampouco relacionados ao deslocamento do balão intra-aórtico durante o protocolo de exercícios. O programa de exercícios resultou em maior SvO2 com aumento do TC6min e menores escores de dispneia de Borg (312 metros vs. 488 metros e cinco pontos vs. três pontos, respectivamente). Após completar o protocolo de exercícios de dez dias, o paciente foi submetido a uma cirurgia de transplante cardíaco sem complicações e recuperação total na UTI. O presente estudo demonstrou que o exercício é uma opção viável para pacientes com choque cardiogênico em uso de balão intra-aórtico e que é bem tolerado, além de não haver relatos de eventos adversos.

AIMS: Despite increased temporary mechanical circulatory support (tMCS) utilization for acute myocardial infarction complicated by cardiogenic shock (AMI-CS), data regarding efficacy and optimal timing for tMCS support are limited. This study aimed to describe outcomes based on tMCS timing in AMI-CS and to identify predictors of 30-day mortality and readmission. METHODS AND RESULTS: Patients with AMI-CS identified in the National Readmissions Database were grouped according to the use of tMCS and early (<24â h) vs. delayed (≥24â h) tMCS. The correlation between tMCS timing and inpatient outcomes was evaluated using linear regression. Multivariate logistic regression was used to identify variables associated with 30-day mortality and readmission. Of 294 839 patients with AMI-CS, 109 148 patients were supported with tMCS (8067 veno-arterial extracorporeal membrane oxygenation, 33 577 Impella, and 79 161 intra-aortic balloon pump). Of patients requiring tMCS, patients who received early tMCS (n = 79 906) had shorter lengths of stay (7 vs. 15 days, P < 0.001) and lower rates of ischaemic and bleeding complications than those with delayed tMCS (n = 32 241). Patients requiring tMCS had higher in-hospital mortality [odds ratio (95% confidence interval)] [1.7 (1.7-1.8), P < 0.001]. Among patients requiring tMCS, early support was associated with fewer complications, lower mortality [0.90 (0.85-0.94), P < 0.001], and fewer 30-day readmissions [0.91 (0.85-0.97), P = 0.005] compared with patients with delayed tMCS. CONCLUSION: Among patients receiving tMCS for AMI-CS, early tMCS was associated with fewer complications, shorter lengths of stay, lower hospital costs, and fewer deaths and readmissions at 30 days.

The last several years have seen a rise in use of mechanical circulatory support (MCS) to bridge heart transplant recipients. A controlled hypothermic organ preservation system, the SherpaPak Cardiac Transport System (SCTS), was introduced in 2018 and has grown in utilization with reports of improved posttransplant outcomes. The Global Utilization And Registry Database for Improved heArt preservatioN (GUARDIAN)-Heart registry is an international, multicenter registry assessing outcomes after transplant using the SCTS. This analysis examines outcomes in recipients bridged with various MCS devices in the GUARDIAN-Heart Registry. A total of 422 recipients with donor hearts transported using SCTS were included and identified. Durable ventricular assist devices (VADs) were used exclusively in 179 recipients, temporary VADs or intra-aortic balloon pump (IABP) in 197, and extracorporeal membrane oxygenation (ECMO) in 14 recipients. Average ischemic times were over 3.5 hours in all cohorts. Severe primary graft dysfunction (PGD) posttransplant increased across groups (4.5% VAD, 5.1% temporary support, 21.4% ECMO), whereas intensive care unit (ICU) length of stay (18.2 days) and total hospital stay (39.4 days) was longer in the ECMO cohort than the VAD and IABP groups. A comparison of outcomes of MCS bridging in SCTS versus traditional ice revealed significantly lower rates of both moderate/severe right ventricular (RV) dysfunction and severe PGD in the SCTS cohort; however, upon propensity matching only the reductions in moderate/severe RV dysfunction were statistically significant. Use of SCTS in transplant recipients with various bridging strategies results in excellent outcomes.

AIMS: Due to its low incidence, poor prognosis, and high mortality in the acute phase, the long-term prognosis of the left ventricular aneurysm (LVA) complicated by ventricular septal rupture (VSR) has received little attention. This study focus on the long-term prognosis of patients with LVA complicated by relatively stable VSR. METHODS AND RESULTS: Over a decade of retrospection, 68 patients with both LVA and VSR were compared with 136 patients with LVA alone after propensity score matching. Patients with both LVA and VSR were further divided into two groups depending on whether pre-operative intra-aortic balloon pump (IABP) was used (23 pre-operative IABP vs. 45 non-pre-operative IABP). The primary endpoint was defined as major adverse cardiovascular and cerebrovascular events, a composite endpoint including mortality, myocardial infarction, revascularization, stroke, and heart failure. Patients with both LVA and VSR were generally in a worse condition upon admission compared with those with LVA alone [percentage of patients in New York Heart Association IV: 42.6% (29/68) vs. 11.0% (15/136), P < 0.001]. Both pre-operative and post-operative IABP use rates were significantly higher in patients with both LVA and VSR than in patients with LVA alone [pre-operative IABP use rates: 33.8% (23/68) vs. 0.74% (1/136), P < 0.001 and post-operative IABP use rates: 33.8% (23/68) vs. 10.3% (14/136), P < 0.001]. No significant difference was observed in the primary endpoint between patients with both LVA and VSR and those with LVA alone (log-rank test, P = 0.63, median follow-up time 63 months). We further investigated the effect of pre-operative IABP on the long-term prognosis of patients with both LVA and VSR. Patients who applied pre-operative IABP had a worse long-term prognosis than those who did not (log-rank test, P = 0.0011). CONCLUSIONS: The long-term prognosis of LVA combined with VSR was not inferior than LVA alone after surgery, but poor blood perfusion status was associated with a worse prognosis.

The purpose of this study was to evaluate left ventricular (LV) unloading strategies in patients supported with peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO). A retrospective review was conducted of all consecutive patients requiring VA-ECMO support for any indication, who underwent novel LV unloading strategies with either direct left atrial venoarterial (LAVA) cannulation or pulmonary artery venoarterial (PAVA) venting, in comparison to Impella and intra-aortic balloon pump (IABP). The primary outcome was successful bridge to transplant, LV assist device, or myocardial recovery. Forty-six patients (63% male, mean age 52.8 ± 17.6 years) were included. Fourteen patients (30%) underwent novel unloading with either LAVA or PAVA, 11 patients (24%) underwent IABP placement, and 21 patients (46%) underwent Impella insertion. In the novel LV unloading cohort, 10 patients (71%) survived to hospital discharge. Four patients (29%) were weaned from ECMO and eight patients (57%) underwent cardiac transplantation. Although a trend favoring cannula-based unloading for the primary outcome was noted, the cohort was too small for statistical significance (79% LAVA/PAVA, 57% Impella, 45% IABP; p = 0.21). However, probability of survival was greater in the LAVA/PAVA cohort compared to Impella and IABP ( p < 0.05). Thus, we demonstrate the efficacy of LA and PA cannulation as an alternative LV unloading strategy for patients supported with peripheral VA-ECMO.

BACKGROUND: Glucagon-like peptide-1 (GLP-1) is a gut-derived peptide secreted in response to nutritional and inflammatory stimuli. Elevated GLP-1 levels predict adverse outcome in patients with acute myocardial infarction or sepsis. GLP-1 holds cardioprotective effects and GLP-1 receptor agonists reduce cardiovascular events in high-risk patients with diabetes. In this study, we aimed to investigate the capacity of GLP-1 to predict outcome in patients with cardiogenic shock (CS) complicating myocardial infarction. METHODS: Circulating GLP-1 levels were serially assessed in 172 individuals during index PCI and day 2 in a prospectively planned biomarker substudy of the IABP-SHOCK II trial. All-cause mortality at short- (30 days), intermediate- (1 year), and long-term (6 years) follow-up was used for outcome assessment. RESULTS: Patients with fatal short-term outcome (n = 70) exhibited higher GLP-1 levels [86 (interquartile range 45-130) pM] at ICU admission in comparison to patients with 30-day survival [48 (interquartile range 33-78) pM; p < 0.001] (n = 102). Repeated measures ANOVA revealed a significant interaction of GLP-1 dynamics from baseline to day 2 between survivors and non-survivors (p = 0.04). GLP-1 levels above vs. below the median proved to be predictive for short- [hazard ratio (HR) 2.43; 95% confidence interval (CI) 1.50-3.94; p < 0.001], intermediate- [HR 2.46; 95% CI 1.62-3.76; p < 0.001] and long-term [HR 2.12; 95% CI 1.44-3.11; p < 0.001] outcome by multivariate Cox-regression analysis. CONCLUSION: Elevated plasma levels of GLP-1 are an independent predictor for impaired prognosis in patients with myocardial infarction complicated by CS. The functional relevance of GLP-1 in this context is currently unknown and needs further investigations. TRIAL REGISTRATION: www. CLINICALTRIALS: gov Identifier: NCT00491036.

Infections from prolonged use of axillary intra-aortic balloon pumps (IABPs) have not been well studied. Bloodstream infection (BSI) occurred in 13% of our patients; however, no difference in outcome was noted between those with BSI and those without. Further studies regarding protocol developments that minimize BSI risk are needed.

INTRODUCTION: The intra-aortic balloon pump (IABP) is one of the most utilized cardiac assist devices. Patients receiving IABP therapy are typically managed in high acuity clinical care areas with limited bed space and high demand. Our center instituted a certified clinical perfusionist (CCP) led initiative to remove IABP catheters in order to reduce IABP therapy time, hasten removal and improve efficiency. METHODS: The purpose of the study is to compare outcomes for IABP removal by a certified clinical perfusionist to a physician. The primary outcome measures were site hematoma score and limb related complications. A survey was submitted to bedside nurses, managers/patient care coordinators, CCP's and physicians. The IABP quality assurance database was interrogated for the study. RESULTS: There were 350 patients eligible for inclusion. The cohort was well balanced between CCP (n = 284) and physician (n = 66) groups for patient demographics, indication, insertion specifics and type of medical intervention. The majority of patients had no bruise or hematoma with perfusionist (n = 246, 87%) or physician (n = 58, 88%) (p = 0.78) removal. The physician group demonstrated a higher rate of grade 3 hematomas (p = 0.03). There was no statistically significant difference between CCP and physician groups for limb complications and mortality. Survey results showed an improved efficiency in bed space allocation, physician workload and a decreased IABP support time. CONCLUSION: There is no difference in limb complications between perfusionist and physician removal of IABP catheters. The survey demonstrate an improvement in resource allocation and efficiency. A perfusionist led IABP removal program can be done safely and may help improve program efficiency.
