Key Takeaway
Recognize that macrophage-targeted cardiac therapies remain investigational; this review lacks clinical trial data.
This is a review of macrophage biology in cardiac disease. It covers the classification of macrophages into two main groups: embryonic tissue-resident and bone marrow-derived. The review also describes macrophage subsets as having complex functions, including inflammation regulation, tissue repair, metabolic reprogramming, and intercellular communication.
The scope is limited to a conceptual synthesis of macrophage classification and function. No study population, sample size, intervention, comparator, or primary outcome is reported. The review does not present pooled effect sizes, absolute numbers, p-values, or confidence intervals.
The authors discuss potential therapeutic strategies and future research directions. However, the review does not provide specific clinical trial data, and no safety or tolerability information is reported. Limitations, funding, conflicts of interest, and practice relevance are not reported.
Given the absence of clinical trial data, the findings should be interpreted as a mechanistic overview rather than direct clinical guidance. Clinicians should recognize that macrophage-targeted approaches remain investigational, and no specific therapeutic recommendations can be drawn from this review.
This review explores the role of macrophages in cardiac diseases. These are a type of immune cell that the body uses to respond to injury and infection. The research identifies two main groups of these cells based on where they come from: those that live in embryonic tissue and those that come from the bone marrow.
Each group of macrophages performs different tasks. They are involved in complex processes like regulating inflammation, repairing damaged tissue, and communicating with other cells. They also help with metabolic reprogramming in the body. These different functions are important for how the heart responds to various conditions.
Because this is a review of biological processes rather than a clinical trial, the findings do not provide specific medical treatments or drug data. The research focuses on how these cells work at a cellular level. These findings help scientists understand the underlying biology of heart disease to help plan future research.
What this means for you:
Different types of macrophages perform complex roles in inflammation and tissue repair in heart diseases.
Common questions
What are macrophages and how do they affect heart health?
Macrophages are immune cells that play a vital role in the body. They are divided into two main groups: embryonic tissue-resident and bone marrow-derived. These cells perform complex functions such as regulating inflammation, repairing tissue, and communicating with other cells in the body.
What specific roles do these immune cells play?
Different subsets of macrophages have complex functions. They are involved in inflammation regulation, tissue repair, metabolic reprogramming, and intercellular communication. These processes are important for how the body responds to and manages cardiac diseases.

Macrophages are important immune cells for cardiac development, homeostasis, and the response to pathological injury and inflammation. Single-cell sequencing and fate-mapping technologies have revealed the heterogeneity and development of cardiac macrophages. They are classed into two main groups: embryonic tissue-resident and bone marrow-derived macrophages. These different macrophage subsets show complex functions in cardiac diseases such as inflammation regulation, tissue repair, metabolic reprogramming and intercellular communication within the cardiac microenvironment. This review discusses the developmental sources, phenotypic diversity, metabolic features and mechanistic functions of cardiac macrophages in different cardiac disorders. We focus on macrophage polarization, metabolic regulation during disease progression and targeted strategies and future research directions.
