Abstract

Abstract:

Acute myocardial infarction (AMI) is a threat to human life and physical health worldwide. Timely reperfusion is very important to limit infarct size and protect ischemic myocardium. Unfortunately, it has also caused severer myocardial damage, which is called “myocardial ischemia/ reperfusion injury (MIRI)”. There is no effective clinical treatment for it. Over the past two decades, biological studies of NF-κB have improved the understanding of MIRI. Nuclear Factor-κB (NF-κB) is a major transcription factor associated with cardiovascular health and disease. It is involved in the release of pro-inflammatory factors and apoptosis of cardiomyocytes. Recent studies have shown that inhibition of NF-κB plays a protective role in acute hypoxia and reperfusion injury. Here we review the molecular regulation of NF-κB in MIRI, better understanding of NF-κB signaling mechanisms related to inflammation and crosstalk with endogenous small molecules. We hope this review will aid in improving therapeutic approaches to clinical diagnosing. This review provides evidence for the role of NF-κB in MIRI and supports its use as a therapeutic target.

NF-κB signaling in inflammation

Ting Ting Liu, Lingyun Zhang, Donghyun Joo … (2017)

The transcription factor NF-κB regulates multiple aspects of innate and adaptive immune functions and serves as a pivotal mediator of inflammatory responses. NF-κB induces the expression of various pro-inflammatory genes, including those encoding cytokines and chemokines, and also participates in inflammasome regulation. In addition, NF-κB plays a critical role in regulating the survival, activation and differentiation of innate immune cells and inflammatory T cells. Consequently, deregulated NF-κB activation contributes to the pathogenic processes of various inflammatory diseases. In this review, we will discuss the activation and function of NF-κB in association with inflammatory diseases and highlight the development of therapeutic strategies based on NF-κB inhibition.

Heart Disease and Stroke Statistics—2021 Update: A Report From the American Heart Association

Salim S. Virani, Alvaro Alonso, Hugo Aparicio … (2021)

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 2021 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, an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors related to cardiovascular disease. Each of the 27 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, policy makers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.
