O. Chioncel et al. Cardiogenic shock (CS) is a complex multifactorial clinical syndrome with extremely high mortality, developing as a continuum, and progressing from the initial insult (underlying cause) to the subsequent occurrence of organ failure and death. There is a large spectrum of CS presentations resulting from the interaction between an acute cardiac insult and a patient's underlying cardiac and overall medical condition. Phenotyping patients with CS may have clinical impact on management because classification would support initiation of appropriate therapies. CS management should consider appropriate organization of the health care services, and therapies must be given to the appropriately selected patients, in a timely manner, whilst avoiding iatrogenic harm. Although several consensus-driven algorithms have been proposed, CS management remains challenging and substantial investments in research and development have not yielded proof of efficacy and safety for most of the therapies tested, and outcome in this condition remains poor. Future studies should consider the identification of the new pathophysiological targets, and high-quality translational research should facilitate incorporation of more targeted interventions in clinical research protocols, aimed to improve individual patient outcomes. Designing outcome clinical trials in CS remains particularly challenging in this critical and very costly scenario in cardiology, but information from these trials is imperiously needed to better inform the guidelines and clinical practice. The goal of this review is to summarize the current knowledge concerning the definition, epidemiology, underlying causes, pathophysiology and management of CS based on important lessons from clinical trials and registries, with a focus on improving in-hospital management.

Background Trastuzumab improves dramatically the prognosis of HER2‐positive breast cancer patients, but it may lead to cardiotoxicity with left ventricular (LV) systolic dysfunction. Its effects on right ventricular (RV) function have not however been elucidated. We sought to assess LV and RV deformation mechanics during treatment with trastuzumab in breast cancer patients. Methods and results We studied 101 consecutive women (mean age 54.3 ± 11.4 years) receiving trastuzumab for 12 months; 62 of them (61.4%) had previously received anthracyclines and 26 (25.7%) were receiving taxanes concurrently with trastuzumab. Comprehensive two‐dimensional echocardiography with speckle tracking imaging of LV and RV global longitudinal strain (GLS) and RV free wall longitudinal strain (FWLS) analyses were performed at baseline and every 3 months up to treatment completion. Cardiotoxicity was defined as a decrease of baseline LV ejection fraction > 10 percentage units to a value < 50%. At 3 months, only LV GLS was significantly reduced (−19.5 ± 2.7 to −18.7 ± 2.8, P = 0.0410), while at 6 months, LV GLS, RV GLS and RV FWLS had significantly declined reaching their lowest values (−17.9 ± 6.1, P = 0.002, −19.6 ± 5.2, P = 0.003 and −19.7 ± 5.6, P = 0.004, respectively). Ten women (9.9%) developed cardiotoxicity. A RV GLS percent change of −14.8% predicted cardiotoxicity with 66.7% sensitivity and 70.8% specificity (area under the curve 0.68, 95% confidence interval 0.54–0.81), classifying correctly 90% of women with cardiotoxicity. This cut‐off is quite similar to the 15% change of LV GLS previously suggested as predictive of cardiotoxicity. Conclusions Deformation mechanics of both the left and right ventricle follow similar temporal pattern and degree of impairment during trastuzumab therapy, confirming the global and uniform effect of trastuzumab on myocardial function.

Heart failure (HF) constitutes the growing cardiovascular burden and the major public health issue, but comprehensive statistics on HF epidemiology and related management in Europe are missing. The Heart Failure Association (HFA) Atlas has been initiated in 2016 in order to close this gap, representing the continuity directly rooted in the European Society of Cardiology (ESC) Atlas of Cardiology. The major aim of the HFA Atlas is to establish a contemporary dataset on HF epidemiology, resources and reimbursement policies for HF management, organization of the National Heart Failure Societies (NHFS) and their major activities, including education and HF awareness. These data are gathered in collaboration with the network of NHFS of the ESC member and ESC affiliated countries. The dataset will be continuously improved and advanced based on the experience and enhanced understanding of data collection in the forthcoming years. This will enable revealing trends, disparities and gaps in knowledge on epidemiology and management of HF. Such data are highly needed by the clinicians of different specialties (aside from cardiologists and cardiac surgeons), researchers, healthcare policy makers, as well as HF patients and their caregivers. It will also allow to map the snapshot of realities in HF care, as well as to provide insights for evidence-based health care policy in contemporary management of HF. Such data will support the ESC/HFA efforts to improve HF management and outcomes through stronger recommendations and calls for action. This will likely influence the allocation of funds for the prevention, treatment, education and research in HF.
