Background And Aims: Cardiovascular disease (CVD) impacts significantly health and social care systems as well as society through premature mortality and disability, with patients requiring care from relatives. Previous pan-European estimates of the economic burden of CVD are now outdated. This study aims to provide novel, up-to-date evidence on the economic burden across the 27 European Union (EU) countries in 2021.

Article Synopsis
  • Cardiovascular disease (CVD) is the top cause of death in Europe, leading to significant productivity losses estimated at €62 billion in 2018 due to 4.4 million deaths and 7.1 million working years lost.
  • Coronary heart disease was responsible for 47% of these costs (€29 billion), while cerebrovascular disease contributed 18% (€11 billion).
  • The findings suggest that targeted policies for prevention and care of CVD could yield substantial economic benefits, especially in the 28 EU member states where a majority of the productivity losses occurred.

This Review provides an epidemiological overview of global mortality from acute coronary syndromes (ACS). Across the regions of the world where data are available, mortality from ACS - including premature (age <70 years) mortality from ACS - was higher in men than in women. In both sexes, age-standardized mortality rates (ASMRs) for ACS in 2020 were highest in lower-income global regions.

Purpose Of Review: Prior European Society of Cardiology (ESC) guidelines endorsed the SCORE 10-year cardiovascular disease (CVD) risk calculator to inform the total risk approach to CVD prevention, including the use of preventive interventions like lipid lowering therapies. However, SCORE was released in 2003, did not allow for estimation of fatal and non-fatal CVD events, and was limited to adults aged 40 to 70 years. The ESC's Cardiovascular Risk Collaboration (CRC) was tasked with updating SCORE (SCORE2) and with extending the upper age range of adults eligible for risk estimation (SCORE2-OP).

Clinical estimation of the combined effect of several risk factors is unreliable and this resulted in the development of a number of risk estimation systems to guide clinical practice. Here, after defining general principles of risk estimation, the authors describe the evolution of the European Society of Cardiology's (ESC) Systematic COronary Risk Evaluation (SCORE) risk estimation system and some learnings from the data. They move on to describe the establishment of the ESC's Cardiovascular Risk Collaboration and outline its proposed research directions.

Src homology 2 (SH2) domains are key modulators in various signaling pathways allowing the recognition of phosphotyrosine sites of different proteins. Despite the fact that SH2 domains acquire their biological functions in a monomeric state, a multitude of reports have shown their tendency to dimerize. Here, we provide a technical description on how to isolate and characterize by gel filtration, circular dichroism (CD), and nuclear magnetic resonance (NMR) each conformational state of p59 SH2 domain.

Src kinase activity is controlled by various mechanisms involving a coordinated movement of kinase and regulatory domains. Notwithstanding the extensive knowledge related to the backbone dynamics, little is known about the more subtle side-chain dynamics within the regulatory domains and their role in the activation process. Here, we show through experimental methyl dynamic results and predicted changes in side-chain conformational couplings that the SH2 structure of Fyn contains a dynamic network capable of propagating binding information.

Src homology 2 domains are interaction modules dedicated to the recognition of phosphotyrosine sites incorporated in numerous proteins found in intracellular signaling pathways. Here we provide for the first time structural insight into the dimerization of Fyn SH2 both in solution and in crystalline conditions, providing novel crystal structures of both the dimer and peptide-bound structures of Fyn SH2. Using nuclear magnetic resonance chemical shift analysis, we show how the peptide is able to eradicate the dimerization, leading to monomeric SH2 in its bound state.

Src homology 2 (SH2) domains have an important role in the regulation of protein activity and intracellular signaling processes. They are geared to bind to specific phosphotyrosine (pY) motifs, with a substrate sequence specificity depending on the three amino acids immediately C-terminal to the pY. Here we report for the first time the (1)H, (15)N and (13)C backbone and side-chain chemical shift assignments for the C-terminal SH2 domain of the human protein tyrosine phosphatase PTPN11, both in its free and bound forms, where the ligand in the latter corresponds to a specific sequence of the human erythropoietin receptor.
