Abstract Introduction Cardiogenic shock is linked with eminent morbidity and mortality despite advances in treatment modality. Adjuvant treatment modalities to provide mechanical haemodynamic support in the form of intra-aortic balloon pump (IABP) or Impella are being used among patients with cardiogenic shock. The Impella prunes left ventricular preload, whereas, IABP persuades after load reduction and both contribute to improved cardiac output. A few underpowered randomised control trials (RCTs) and observational studies compared short term mortality benefit of Impella juxtaposed to IABP among patients with cardiogenic shock. Purpose A meta-analysis of RCTs and observational studies researching the short-term mortality in cardiogenic shock comparing Impella to IABP was executed. Methods The databases PubMed, EMBASE and Cochrane were searched systematically to identify relevant RCTs and observational studies contrasting Impella to IABP and reporting 30-days mortality as outcomes. The search terms used were “Impella”, “IAPB”, “intra-aortic balloon pump” and all word variations were utilised. The search was conducted from the debut of the databases up to January 2020. Two reviewers independently and in tandem performed data screening and extraction from identified articles. Inverse variance method with Paule-Mandel estimator for tau2 and Hartung-Knapp adjustment was used to calculate Risk Ratio with 95% confidence interval. Heterogeneity was assessed using I2 statistics. Furthermore, we calculated the 95% predictive interval for the pooled estimate. All statistical analysis for this meta-analysis was carried out using R statistical software version 3.6.2 using the package meta ( ). Additionally, Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria were used to assess the certainty of evidence. Results Five studies constituting 728 patients were included in the final analysis. Two were RCTs (ISAR-SHOCK trial and IMPRESS in Severe Shock trial), one study was a propensity score matched observational study and two were unmatched observational studies. There was no difference in the risk of 30-days mortality in patients treated with Impella as compared to IABP [Risk Ratio: 0.97, 95% confidence interval: 0.66–1.41, I2: 32%]. To account for the heterogeneity, we calculated 95% predictive interval: 0.46–2.02. Thus, very low certainty of evidence concluded no difference in the risk of 30-days mortality among cardiogenic shock patients treated with Impella in opposition to IABP. Conclusion This meta-analysis comparing Impella juxtaposed with IABP demonstrated no difference in the risk of 30-days mortality among patients with cardiogenic shock. 30-days Mortality Funding Acknowledgement Type of funding source: None

Abstract Background: In the current SARS-CoV-2 pandemic, there has been worldwide debate on the use of corticosteroids in COVID-19. In the recent RECOVERY trial, evaluating the effect of dexamethasone, a reduced 28-day mortality in patients requiring oxygen therapy or mechanical ventilation was shown. Their results have led to considering amendments in guidelines or actually already recommending corticosteroids in COVID-19. However, the effectiveness and safety of corticosteroids still remain uncertain, and reliable data to further shed light on the benefit and harm are needed. Objectives: The aim of this systematic review and meta-analysis was to evaluate the effectiveness and safety of corticosteroids in COVID-19. Methods: A systematic literature search of RCTS and observational studies on adult patients was performed across Medline/PubMed, Embase, and Web of Science from 1st of December 2019 until 1 st of October 2020, according to the PRISMA guidelines. Primary outcomes were short-term mortality and viral clearance (based on RT-PCR in respiratory specimens). Secondary outcomes were: need for mechanical ventilation, other oxygen therapy, length of hospital stay and secondary infections. Results: Forty-four studies were included, covering 20.197 patients. In twenty-two studies, the effect of corticosteroid use on mortality was quantified. The overall pooled estimate (observational studies and RCTs) showed a significant reduced mortality in the corticosteroid group (OR 0.72 (95%CI 0.57-0.87). Furthermore, viral clearance time ranged from 10-29 days in the corticosteroid group and from 8-24 days in the standard of care group. Fourteen studies reported a positive effect of corticosteroids on need for and duration of mechanical ventilation. A trend towards more infections and antibiotic use was present. Conclusions: Our findings from both observational studies and RCTs confirm a beneficial effect of corticosteroids on short-term mortality and a reduction of need for mechanical ventilation. And although data in the studies were too sparse to draw any firm conclusions, there might be a signal of delayed viral clearance and an increase in secondary infections.

Coronary Syndromes

Acute cardiovascular disease after community-acquired pneumonia is a well-accepted complication for which definitive treatment strategies are lacking. These complications share some common features but have distinct diagnostic and treatment approaches. We therefore undertook an updated systematic review and meta-analysis of observational studies reporting the incidence of overall complications, acute coronary syndromes, new or worsening heart failure, new or worsening arrhythmias and acute stroke, as well as short-term mortality outcomes. To set a framework for future research, we further included a holistic review of the interplay between the two conditions. From 1984 to 2019, thirty-nine studies were accrued, involving 92,188 patients, divided by setting (inpatients versus outpatients) and clinical severity (low risk versus high risk). Overall cardiac complications occurred in 13.9% (95% confidence interval (CI) 9.6–18.9), acute coronary syndromes in 4.5% (95% CI 2.9–6.5), heart failure in 9.2% (95% CI 6.7–12.2), arrhythmias in 7.2% (95% CI 5.6–9.0) and stroke in 0.71% (95% CI 0.1–3.9) of pooled inpatients. During this period, meta-regression analysis suggests that the incidence of overall and individual cardiac complications is decreasing. After adjusting for confounders, cardiovascular events taking place after community-acquired pneumonia independently increase the risk for short-term mortality (range of odds-ratio: 1.39–5.49). These findings highlight the need for effective, large trial based, preventive and therapeutic interventions in this important patient population.

Abstract Introduction Percutaneous mechanical circulatory support devices are increasingly used in acute cardiogenic shock (CS), despite limited evidence for their effectiveness. The aim of this study was to evaluate outcomes associated with use of the full support Impella 5 and 5.5 as a short- term left ventricular device (LVAD) and to identify preoperative predictors of short -term mortality. Methods Data of patients in CS (n=51) treated with the Impella 5 (n=48) and 5.5 (n=3) devices at our institution were collected retrospectively. The primary endpoint was 30-day all-cause mortality. Clinical follow up including adverse events was analyzed. Results Mean age was 58.2±12.1 years; 80.4% were male. 13 patients had BMI >30 kg/m2. CS was caused by acute myocardial infarction (n=14), decompensated chronic heart failure (n=29), postcardiotomy syndrom and acute myocarditis (n=4 each). Before implantation, median Intermacs profile was 1 (range 1–3) and 31 patients (61%) were on respiratory support. In 49 patients the axillary artery was used for vascular access (n=4 left and n=45 right) employing a 10mm dacron graft tunneled through the skin, in one patient left femoral artery and ascending aorta, respectively. Median support time was 14 days. In 12 cases the pump was removed for myocardial recovery. In 15 patients a continuous flow permanent LVAD was implanted. Bleeding (n=9), thromboembolic event (n=5), pump dislodgement (n=7) requiring revision occurred during support. Seven patients developed ventricular arrhythmia requiring flow reduction. In 5 cases the pump was explanted for hemolysis, in 2 other patients pump exchange was performed. The overall 30-day survival was 53% (95% CI: 38.8–67.1%). Penalized multivariable logistic regression analysis identified preoperative elevated lactate (p=0.027) and CK-MB (p=0.022) as predictors for 30- day mortality. On the basis of these data, a nomogram to estimate 30d-mortality after Impella implantation was created. Conclusion Stabilization of patients suffering from CS employing temporary full support Impella LVAD is feasible and results in acceptable survival. Preoperative degree of shock and myocardial damage predict the short-term mortality. Effect of full support Impella LVAD in earlier stages of shock may prevent irreversible end organ damage.

Abstract Background High-flow nasal cannula oxygenation (HFNC) and noninvasive positive-pressure ventilation (NPPV) possibly decrease tracheal reintubation rates better than conventional oxygen therapy (COT); however, few large-scale studies have compared HFNC and NPPV. We conducted a network meta-analysis (NMA) to compare the effectiveness of three post-extubation respiratory support devices (HFNC, NPPV, and COT) in reducing the mortality and reintubation risk. Methods The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Ichushi databases were searched. COT, NPPV, and HFNC use were assessed in patients who were aged ≥ 16 years, underwent invasive mechanical ventilation for > 12 h for acute respiratory failure, and were scheduled for extubation after spontaneous breathing trials. The GRADE Working Group Approach was performed using a frequentist-based approach with multivariate random-effect meta-analysis. Short-term mortality and reintubation and post-extubation respiratory failure rates were compared. Results After evaluating 4631 records, 15 studies and 2600 patients were included. The main cause of acute hypoxic respiratory failure was pneumonia. Although NPPV/HFNC use did not significantly lower the mortality risk (relative risk [95% confidence interval] 0.75 [0.53–1.06] and 0.92 [0.67–1.27]; low and moderate certainty, respectively), HFNC use significantly lowered the reintubation risk (0.54 [0.32–0.89]; high certainty) compared to COT use. The associations of mortality with NPPV and HFNC use with respect to either outcome did not differ significantly (short-term mortality and reintubation, relative risk [95% confidence interval] 0.81 [0.61–1.08] and 1.02 [0.53–1.97]; moderate and very low certainty, respectively). Conclusion NPPV or HFNC use may not reduce the risk of short-term mortality; however, they may reduce the risk of endotracheal reintubation.

Background: Early revascularisation of the culprit lesion is the therapeutic cornerstone in cardiogenic shock complicating acute myocardial infarction. The optimal management of additional non-culprit lesions is unclear. This systematic review and meta-analysis aims to summarise current evidence on the comparison of immediate multivessel percutaneous coronary intervention (MV-PCI) or culprit lesion only PCI with possible staged revascularisation (C-PCI) in patients with cardiogenic shock complicating acute myocardial infarction. Methods: Medical literature databases were screened to identify analyses comparing MV-PCI with C-PCI in patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease. In absence of randomised trials, 10 cohort studies were included in the current meta-analysis. The primary outcome of short-term mortality was assessed at hospital discharge or 30 days after hospital admission. Secondary outcomes were long-term mortality as well as myocardial re-infarction, stroke, acute renal failure, and bleeding at short-term follow-up. Results: Of 6051 patients, 1194 (19.7%) received MV-PCI and 4857 (80.3%) C-PCI. Short-term mortality was 37.5% in patients undergoing MV-PCI compared with 28.8% in C-PCI patients (risk ratio 1.26, 95% confidence interval 1.12–1.41, p=0.001). Long-term mortality ( p=0.77), myocardial re-infarction ( p=0.77), stroke ( p=0.12), acute renal failure ( p=0.17) and bleeding ( p=0.53) did not differ significantly between the two revascularisation groups. Conclusions: Results of this first meta-analysis on the interventional management of patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease do not support MV-PCI over C-PCI. However, possible treatment selection bias in the individual studies must be taken into account.

Successful Weaning

Introduction: Veno-arterial extracorporeal membrane oxygenation may be used to support patients with refractory cardiogenic shock. Many patients can be successfully weaned, the ability of some medications to facilitate weaning from veno-arterial extracorporeal membrane oxygenation were reported. To date, there are limited studies investigating the impact of levosimendan on veno-arterial extracorporeal membrane oxygenation weaning. The objective of this systematic review and meta-analysis was to assess the effects of levosimendan on successful weaning from veno-arterial extracorporeal membrane oxygenation and survival in adult patients with cardiogenic shock. Methods: We performed a systematic review and meta-analysis (PubMed, the Cochrane Library, and the International Clinical Trials Registry Platform published from the year 2000 onwards) investigating whether levosimendan offers advantages compared to standard therapy or placebo, in cardiogenic shock adult patients treated with veno-arterial extracorporeal membrane oxygenation. The primary outcome was veno-arterial extracorporeal membrane oxygenation successful weaning, whereas secondary outcome was all-cause mortality at the longest follow-up available. We pooled risk ratio and 95% confidence interval using fixed and random effects models according to the heterogeneity. Results: A total of five non-randomized clinical trials comprising 557 patients were included, 299 patients for levosimendan and 258 patients for control groups. The pooled prevalence of veno-arterial extracorporeal membrane oxygenation successful weaning was 61.4% (95% confidence interval 39.8-82.9%), and all-cause mortality was 36% (95% confidence interval 29.6-48.8%). There was a significant increase in veno-arterial extracorporeal membrane oxygenation successful weaning with levosimendan compared to the controls (risk ratio = 1.42 (95% confidence interval 1.12-1.8), p for effect = 0.004, I2 = 71%). A decrease risk of all-cause mortality in the levosimendan group was also observed, risk ratio = 0.62 (95% confidence interval 0.44-0.88), p for effect = 0.007, I2 = 36%. Conclusion: The use of levosimendan on adult patients with cardiogenic shock may facilitate the veno-arterial extracorporeal membrane oxygenation weaning and reduce all-cause mortality. Few articles of this topic are available, and prospective, randomized multi-center trials are warranted to conclude decisively on the benefits of levosimendan in this setting.
