Recent findings have implicated leukocytes subclasses and multiple inflammatory mediators in the progression of heart failure and cardiovascular disease. Studies have discovered further details on the interaction between immune cells-particularly macrophages and lymphocytes-and inflammation. There are both cell-mediated and cytokine-mediated pathways of inflammation, which are interconnected. Additionally, a number of markers have been used and studied in heart failure disease progression. In this review, we discuss inflammatory biomarkers and immune cell mediators involved in HF. We will focus on the correlations and role of these inflammatory mediators in the genesis of HF. We will also discuss the evidence on beneficial effects of anti-inflammatory agents in the setting of chronic HF.
Atherosclerosis is a chronic inflammatory disease. Pathophysiological similarities between chronic infections and atherosclerosis triggered interest in a clinical association between these conditions. Various infectious microbes have been linked to atherosclerotic vascular disease in epidemiological studies. However, this association failed to satisfy the Koch's postulates of causation with multiple clinical trials demonstrating inefficacy of anti-infective therapies in mitigating atherosclerotic cardiovascular events. Identification of underlying pathophysiological mechanisms and experience with vaccination against various infectious agents has ushered a new avenue of efforts in the development of an anti-atherosclerotic vaccine. Studies in animal models have identified various innate and adaptive immune pathways in atherosclerosis. In this review, we discuss the patho-biological link between chronic infections and atherosclerosis, evaluate existing evidence of animal and human trials on the association between infections and cardiovascular disease and introduce the concept of an anti-atherosclerotic vaccine.
Studies support the concept of a significant gender difference in ANS activity. Further studies are indicated to elucidate specific differences and mechanisms, which could guide targeted therapy of various cardiovascular disease states.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
