The immune response holds a pivotal role in cardiovascular disease development.As multifunctional cells of the innate immune system,macrophages play an essential role in initial inflammatory response that occurs following cardiovascular injury,thereby inducing subsequent damage while also facilitating recovery.Meanwhile,the diverse phenotypes and phenotypic alterations of macrophages strongly associate with distinct types and.severity of cardiovascular diseases,including coronary heart disease,valvular disease,myocarditis,cardiomyopathy,heart failure,atherosclerosis and aneurysm,which underscores the importance of investigating macrophage regulatory mechanisms within the context of specific diseases.Besides,recent strides in single-cell sequencing technologies have revealed macrophage heterogeneity,cell-cell interactions,and downstream mechanisms of therapeutic targets at a.higher resolution,which brings new perspectives into macrophage-mediated mechanisms and potential therapeutic targets in cardiovascular diseases.Remarkably,myocardial fibrosis,a prevalent characteristic in most cardiac diseases,remains a formidable clinical challenge,necessitating a profound investigation into the impact of macrophages on myocardial fibrosis within the context of cardiac diseases.In this review,we systematically summarize the diverse phenotypic and functional plasticity of macrophages in regulatory mechanisms of cardiovascular diseases and unprecedented insights introduced by single-cell sequencing technologies,with a focus on different causes and characteristics of diseases,especially the relationship between inflammation and fibrosis in cardiac diseases(myocardial infarction,pressure overload,myocarditis,dilated cardiomyopathy,diabetic cardiomyopathy and cardiac aging)and the relationship between inflammation and vascular injury in vascular diseases(atherosclerosis and aneurysm).Finally,we also highlight the preclinical/clinical macrophage targeting strategies and translational implications.
