Cardiovascular diseases remain the leading cause of mortality worldwide. Recent research has highlighted the intricate interplay between gut microbiota and cardiovascular health. This comprehensive review aims to elucidate the role of gut microbiota in the development and progression of cardiovascular diseases. We discuss the influence of gut microbiota on key processes such as inflammation, metabolism, and endothelial dysfunction, and explore potential therapeutic interventions targeting the gut microbiota to prevent or treat CVDs.
Cardiovascular diseases encompass a range of conditions affecting the heart and blood vessels, including coronary artery disease, stroke, and hypertension. Despite advances in medical care, CVDs remain a significant global health burden, underscoring the need for a deeper understanding of their etiology and potential therapeutic interventions. In recent years, the gut microbiota has emerged as a crucial player in maintaining overall health and has been implicated in various diseases, including CVDs. This review provides a comprehensive overview of the role of gut microbiota in the development and progression of cardiovascular diseases [1-3].
The human gastrointestinal tract harbors a complex ecosystem of microorganisms collectively known as the gut microbiota, which plays a crucial role in maintaining health and homeostasis. This diverse community consists primarily of bacteria but also includes viruses, fungi, and archaea. The composition and diversity of gut microbiota vary among individuals and can be influenced by various factors including diet, host genetics, age, geography, and medications such as antibiotics. Understanding the composition and diversity of gut microbiota is essential for elucidating its role in health and disease, including its impact on cardiovascular health.
The gut microbiota is composed of thousands of bacterial species, with the predominant phyla being Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. Within these phyla, numerous genera and species exist, each contributing to the overall composition and functionality of the microbiota. Some of the most common genera found in the human gut include Bacteroides, Faecalibacterium, Ruminococcus, and Bifidobacterium. The composition of gut microbiota can vary significantly between individuals, influenced by factors such as diet, lifestyle, geography, and host genetics. For example, individuals following plant-based diets tend to have a higher abundance of fiber-degrading bacteria such as Prevotella, while those consuming high-fat diets may exhibit increased levels of bile-tolerant bacteria such as Bilophila and Alistipes.
Microbial diversity refers to the variety of microorganisms present within a community and is a key indicator of ecosystem stability and resilience. High microbial diversity in the gut is generally associated with better health outcomes, as it reflects a more robust and balanced ecosystem capable of performing various metabolic functions. A diverse diet rich in fiber and plant-based foods promotes microbial diversity by providing a wide range of substrates for bacterial fermentation. Antibiotics can disrupt the gut microbiota, leading to decreased microbial diversity and potentially allowing opportunistic pathogens to proliferate.
Microbial diversity tends to decrease with age, with older individuals often exhibiting lower species richness and altered community composition compared to younger individuals. Host genetic factors can influence the composition and diversity of gut microbiota, although the extent of this influence remains an active area of research. Environmental exposures, such as urbanization and sanitation practices, may also impact gut microbiota diversity.The composition and diversity of gut microbiota have been linked to cardiovascular health through various mechanisms, including modulation of inflammation, metabolism, and endothelial function [4,5]. Dysbiosis, characterized by alterations in the composition and function of gut microbiota, has been associated with increased risk of cardiovascular diseases such as atherosclerosis, hypertension, and heart failure.
Understanding the factors that influence gut microbiota composition and diversity is essential for developing targeted interventions to modulate the microbiota and improve cardiovascular outcomes. Strategies such as dietary modifications, probiotics, prebiotics, and fecal microbiota transplantation hold promise for promoting a diverse and balanced gut microbiota, thereby reducing the risk of cardiovascular diseases and improving overall health. Further research is needed to elucidate the specific microbial signatures associated with cardiovascular health and to develop personalized interventions based on individual gut microbiota profiles. The gut microbiota comprises trillions of microorganisms, including bacteria, viruses, fungi, and archaea, residing in the gastrointestinal tract.
The composition and diversity of gut microbiota can be influenced by various factors such as diet, antibiotics, and host genetics. Dysbiosis, characterized by alterations in the composition and function of gut microbiota, has been associated with several diseases, including CVDs. Chronic low-grade inflammation is a hallmark of cardiovascular diseases. Gut microbiota play a pivotal role in modulating systemic inflammation through the production of metabolites such as short-chain fatty acids and lipopolysaccharides, which can influence immune cell function and cytokine production. Dysbiosis-induced inflammation contributes to endothelial dysfunction, atherosclerosis, and other CVDs.
The gut microbiota plays a crucial role in regulating host metabolism through the fermentation of dietary fibers, production of metabolites, and modulation of energy extraction from food. Imbalances in gut microbial communities have been linked to metabolic disorders such as obesity, diabetes, and dyslipidemia, all of which are risk factors for CVDs. Endothelial dysfunction, characterized by impaired vasodilation and pro-inflammatory state of endothelial cells, is a key early event in the development of atherosclerosis. Gut microbiota-derived metabolites, such as trimethylamine N-oxide (TMAO), have been implicated in the pathogenesis of endothelial dysfunction and atherosclerosis.
Additionally, gut microbiota-mediated inflammation can contribute to endothelial dysfunction through various mechanisms. Modulating gut microbiota composition and function represents a promising therapeutic strategy for preventing and treating cardiovascular diseases. Approaches such as probiotics, prebiotics, dietary interventions, and fecal microbiota transplantation have shown potential in modulating gut microbiota and improving cardiovascular health in preclinical and clinical studies.
Accumulating evidence suggests a significant role for gut microbiota in the development and progression of cardiovascular diseases. Dysbiosis-induced inflammation, metabolic disturbances, and endothelial dysfunction contribute to the pathogenesis of CVDs. Targeting the gut microbiota through various therapeutic interventions holds promise for mitigating cardiovascular risk factors and improving patient outcomes. Further research is warranted to elucidate the intricate mechanisms underlying the gut-cardiovascular axis and to develop effective microbiota-based therapies for CVDs.
