Khan discuss the central role of PAI-1 in COVID-19. The discovery of medical therapies to reduce morbidity and mortality related to coronavirus disease (COVID-19) remains an area of intense ...investigation. Han and Pandey describe an elegant set of in vitro experiments to investigate cellular mechanisms underlying SARS-CoV-2-triggered endothelial dysfunction in human pulmonary microvascular endothelial cells (HPMECs). The central finding of their work is the robust release of PAI-1 by HPMECs in response to the uptake of recombinant SARS-CoV-2 spike protein (S1).
Summary
Biological aging is associated with a reduction in the reparative and regenerative potential in tissues and organs. This reduction manifests as a decreased physiological reserve in response ...to stress (termed homeostenosis) and a time‐dependent failure of complex molecular mechanisms that cumulatively create disorder. Aging inevitably occurs with time in all organisms and emerges on a molecular, cellular, organ, and organismal level with genetic, epigenetic, and environmental modulators. Individuals with the same chronological age exhibit differential trajectories of age‐related decline, and it follows that we should assess biological age distinctly from chronological age. In this review, we outline mechanisms of aging with attention to well‐described molecular and cellular hallmarks and discuss physiological changes of aging at the organ‐system level. We suggest methods to measure aging with attention to both molecular biology (e.g., telomere length and epigenetic marks) and physiological function (e.g., lung function and echocardiographic measurements). Finally, we propose a framework to integrate these molecular and physiological data into a composite score that measures biological aging in humans. Understanding the molecular and physiological phenomena that drive the complex and multifactorial processes underlying the variable pace of biological aging in humans will inform how researchers assess and investigate health and disease over the life course. This composite biological age score could be of use to researchers seeking to characterize normal, accelerated, and exceptionally successful aging as well as to assess the effect of interventions aimed at modulating human aging.
HF-related CVD mortality rates were ascertained using the multiple cause of death files from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research, ...which includes the underlying and contributing cause of death from all death certificates in the United States (2). Prior reports from the CARDIA (Coronary Artery Risk Development in Young Adults) study identified a 20-times higher incidence of HF among black men and women compared with whites before the age of 50 years with HF diagnosis associated with higher rates of antecedent risk factors (4). ...racial differences in competing risk for non-CVD deaths (e.g., homicide, opioid overdose, and HIV) may also contribute to the observed trends in HF-related CVD death.
COVID-19 may be linked with heart failure with preserved ejection fraction through several pathways. It must be recognized as a potential risk factor for this kind of heart disease given the ...available evidence.
The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk ...factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).
The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2022 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population and an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, and the global burden of cardiovascular disease and healthy life expectancy.
Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.
The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.
PAI-1 (plasminogen activator inhibitor-1) is a member of the evolutionarily conserved serine protease inhibitor family and a potent and rapid-acting inhibitor of both of the mammalian plasminogen ...activators. Organismal homeostasis requires physiological levels of endogenous PAI-1, and increased PAI-1 production guides the onset and progression of numerous human diseases and contributes to the multimorbidity of aging. Both chronological and stress-induced accelerated aging are associated with cellular senescence and accompanied by marked increases in PAI-1 expression in tissues. Recent studies suggest that PAI-1 is not only a marker but also a key mediator of cellular senescence and organismal aging. Here, we review the significance of PAI-1 as a bonafide marker, as well as a critical mediator, of cellular senescence associated with aging and aging-related pathologies.
BACKGROUND:The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and ...cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).
METHODS:The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year’s worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year’s edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association’s 2020 Impact Goals.
RESULTS:Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.
CONCLUSIONS:The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.
Despite available therapy, mortality and readmission rates within 60-90 days of discharge for patients hospitalized with heart failure (HF) approach 15% and 30%, respectively. This early ...postdischarge period has been termed the 'vulnerable phase' and accounts for a disproportionate amount of the >US$30 billion spent annually on HF care in the USA. The pathophysiology underlying these early adverse events is likely associated with persistently elevated filling pressures at time of discharge and subsequent acute or subacute worsening of postdischarge haemodynamics. Despite limited proven strategies to reduce early adverse events, hospitals in the USA face penalties for 30-day readmission rates that exceed current expectations, and an urgent need exists for novel approaches to improve early postdischarge outcomes. The objective of this Review is to describe the early postdischarge problem among patients hospitalized for HF, the associated patient profile and pathophysiology, and the limitations of current postdischarge treatment strategies. We also identify therapeutic targets and outline a progressive management approach that should be considered by clinicians for reducing early postdischarge morbidity and mortality. Although these strategies require prospective validation, they are practical, affordable, and have the potential to improve patient outcomes substantially after HF hospitalization.
