ABSTRACT

PURPOSE OF REVIEW: Treatment of cardiogenic shock remains largely driven by expert consensus due to limited evidence from randomized controlled trials. In this review, we aim to summarize the approach to the management of patients with cardiogenic shock in the ICU prior to mechanical circulatory support (MCS). RECENT FINDINGS: Main topics covered in this article include diagnosis, monitoring, initial management and key aspects of pharmacological therapy in the ICU for patients with cardiogenic shock. SUMMARY: Despite efforts to improve therapy, short-term mortality in patients with cardiogenic shock is still reaching 40-50%. Early recognition and treatment of cardiogenic shock are crucial, including early revascularization of the culprit lesion with possible staged revascularization in acute myocardial infarction (AMI)-CS. Optimal volume management and vasoactive drugs titrated to restore arterial pressure and perfusion are the cornerstone of cardiogenic shock therapy. The choice of vasoactive drugs depends on the underlying cause and phenotype of cardiogenic shock. Their use should be limited to the shortest duration and lowest possible dose. According to recent observational evidence, assessment of the complete hemodynamic profile with a pulmonary artery catheter (PAC) was associated with improved outcomes and should be considered early in patients not responding to initial therapy or with unclear shock. A multidisciplinary shock team should be involved early in order to identify potential candidates for temporary and/or durable MCS.

ABSTRACT

BACKGROUND: In Europe, more than 300,000 persons per year experience out-of-hospital cardiac arrest (OHCA). Despite medical progress, only few patients survive with good neurological outcome. For many issues, evidence from randomized trials is scarce. OHCA often occurs for cardiac causes. Therefore, we established the national, prospective, multicentre German Cardiac Arrest Registry (G-CAR). Herein, we describe the first results of the pilot phase. RESULTS: Over a period of 16 months, 15 centres included 559 consecutive OHCA patients aged ≥ 18 years. The median age of the patients was 66 years (interquartile range 57;75). Layperson resuscitation was performed in 60.5% of all OHCA cases which were not observed by emergency medical services. The initial rhythm was shockable in 46.4%, and 29.1% of patients had ongoing CPR on hospital admission. Main presumed causes of OHCA were acute coronary syndromes (ACS) and/or cardiogenic shock in 54.8%, with ST-elevation myocardial infarction being the most common aetiology (34.6%). In total, 62.9% of the patients underwent coronary angiography; percutaneous coronary intervention (PCI) was performed in 61.4%. Targeted temperature management was performed in 44.5%. Overall in-hospital mortality was 70.5%, with anoxic brain damage being the main presumed cause of death (38.8%). Extracorporeal cardiopulmonary resuscitation (eCPR) was performed in 11.0%. In these patients, the in-hospital mortality rate was 85.2%. CONCLUSIONS: G-CAR is a multicentre German registry for adult OHCA patients with a focus on cardiac and interventional treatment aspects. The results of the 16-month pilot phase are shown herein. In parallel with further analyses, scaling up of G-CAR to a national level is envisaged. Trial registration ClinicalTrials.gov identifier: NCT05142124.

ABSTRACT

BACKGROUND AND AIMS: Pulmonary Hypertension (PH) represents an aetiologically and clinically heterogeneous disorder accompanied by a severely impaired prognosis. Key steps of PH pathogenesis are vascular and right ventricular myocardial remodelling entailing the re-occurrence of fetal variants of the cell adhesion modulating protein fibronectin (Fn) being virtually absent in healthy adult tissues. These variants are liberated into circulation and are therefore qualified as excellent novel serum biomarkers. Moreover, these molecules might serve as promising therapeutic targets. The current study was aimed at quantifying the serum levels of two functionally important fetal Fn variants (ED-A+ and ED-B+ Fn) in patients suffering from PH due to different aetiologies compared to healthy controls. METHODS: Serum levels of ED-A+ and ED-B+ Fn were quantified using novel ELISA protocols established and validated in our group in 80 PH patients and 40 controls. Results were analysed with respect to clinical, laboratory, echocardiographic and functional parameters. RESULTS: Serum levels of ED-A+ Fn (p = 0.001) but not ED-B+ Fn (p = 0.722) were significantly increased in PH patients compared to healthy controls. Thus, the following analyses were performed only for ED-A+ Fn. When dividing PH patients into different aetiological groups according to current ESC guidelines, the increase in ED-A+ Fn in PH patients compared to controls remained significant for group 1 (p = 0.032), 2 (p = 0.007) and 3 (p = 0.001) but not for group 4 (p = 0.156). Correlation analysis revealed a significant relation between ED-A+ Fn and brain natriuretic peptide (BNP) (r = 0.310; p = 0.002), six minutes' walk test (r = -0.275; p = 0.02) and systolic pulmonary artery pressure (PAPsys) (r = 0.364; p < 0.001). By logistic regression analysis (backward elimination WALD) including a variety of potentially relevant patients' characteristics, only chronic kidney disease (CKD) (OR: 8.866; CI: 1.779-44.187; p = 0.008), C reactive protein (CRP) (OR: 1.194; CI: 1.011-1.410; p = 0.037) and ED-A+ Fn (OR: 1.045; CI: 1.011-1.080; p = 0.009) could be identified as independent predictors of the presence of PH. CONCLUSIONS: Against the background of our results, ED-A+ Fn could serve as a promising novel biomarker of PH with potential value for initial diagnosis and aetiological differentiation. Moreover, it might contribute to more precise risk stratification of PH patients. Beyond that, the future role of ED-A+ Fn as a therapeutic target has to be evaluated in further studies.
