Metformin is highlighted as a potential therapeutic agent beyond diabetes for managing metabolic syndrome, preventing cardiac remodeling, and attenuating ischemia-reperfusion injury.
Does metformin prevent cardiovascular disease and heart failure in patients with metabolic syndrome or pre-diabetes?
Metformin shows potential for novel cardiovascular applications, including the prevention of cardiac fibrosis and heart failure in patients with metabolic syndrome or insulin resistance.
INTRODUCTION: Metformin is a widely used drug in the treatment of type 2 diabetes mellitus (T2DM). However, it is becoming an attractive drug to manage patients with pre-diabetes and to possibly prevent cardiac remodeling and fibrosis and heart failure. AREAS COVERED: In this review, we highlight the novel therapeutic targets of metformin with a special emphasis on cardiovascular disease. We discuss its key mechanisms of action and new signaling pathways that could partially account for its effect. Furthermore, metformin's role in the management of patients with metabolic syndrome is debated, emphasizing its potential to prevent diabetic heart disease. On the other hand, intense research is ongoing to clarify if metformin will be a future drug to target ischemia-reperfusion injury in the setting of myocardial ischemia. EXPERT OPINION: In the following years, one should look carefully at basic science results to successfully design and conduct clinical trials, emphasizing patients without full-blown T2DM, but who otherwise might have increased insulin resistance. Topics such as the prevention of cardiac fibrosis and heart failure with preserved ejection fraction, the attenuation of ischemia-reperfusion injury on an acute coronary syndrome and the post-myocardial infarction left ventricle remodeling surely deserve a special interest and should be faced as potential therapeutic targets for metformin.
Ladeiras‐Lopes et al. (2015) conducted a review in Type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. Metformin was evaluated. Metformin is highlighted as a potential therapeutic agent beyond diabetes for managing metabolic syndrome, preventing cardiac remodeling, and attenuating ischemia-reperfusion injury.
