Abstract

Cardiovascular diseases are one of the leading causes of mortality and morbidity worldwide, with the total number of cases increasing to 523 million in 2019. Despite the advent of new drugs, cardiovascular mortality has increased at an alarming rate of 53.7 % from 12.1 million deaths in 1990. Recently, the role of gut microbiome metabolites, such as Trimethylamine N-Oxide (TMAO), in the pathogenesis of cardiovascular disease (CVD) has attracted significant attention. The gut microbiome is critical in various physiological processes including metabolism, immune function, and inflammation. Elevated TMAO levels are associated with atherosclerosis, heart failure, arrhythmia, and atrial fibrillation. TMAO accelerates atherosclerosis by promoting vascular inflammation and reducing reverse cholesterol transport, which leads to lipid accumulation and vessel narrowing. Previous research has indicated that a Mediterranean diet rich in fiber and phytochemicals can reduce TMAO levels by limiting precursors and fostering beneficial gut microbiota. Prebiotics and probiotics also decrease TMAO, while drugs such as meldonium, aspirin, and antibiotics have shown promise. However, recent studies have demonstrated major potential for the use of statins in reducing TMAO levels. Statin therapy can significantly reduce TMAO levels independent of their cholesterol-lowering effects. This reduction may involve direct interactions with the gut microbiome, changes in cholesterol metabolism, and changes in bile acid composition. This review aims to comprehensively evaluate the therapeutic potential of statins in reducing TMAO levels to improve CV outcomes.

期刊介绍: Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. The journal emphasizes the understanding of mechanism that is relevant to all aspects of human disease and translation to patients. All articles are rigorously reviewed. The Journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms. Articles that merely report observations are rarely accepted. Recommendations from the Declaration of Helsinki or NIH guidelines for care and use of laboratory animals must be adhered to. Articles should be written at a level accessible to readers who are non-specialists in the topic of the article themselves, but who are interested in the research. The Journal welcomes reviews on topics of wide interest to investigators in the life sciences. We particularly encourage submission of brief, focused reviews containing high-quality artwork and require the use of mechanistic summary diagrams.
