Obesity and overweight have become a global problem that development of various coronary artery diseases (CAD), such as myocardial infarction, atherosclerosis and congestive heart failure. Effective diagnosis is needed for effective treatment and prevention, particularly in healthy overweight subject. Platelets is an important component of hemostatic balance, that maintains the coagulation physiology. Platelets are involved in different pathological events such as thrombosis and CAD in various

... nflammatory conditions. There are evidences that highlight an important role of miRNA in regulation of gene expression profiling in platelets. Current hypothesis has shown the likelihood of using miRNAs as diagnostic markers in the event of CAD. This review article describes the association between overweight/obesity and platelets activation in elucidating the gene expression profiling in platelet miRNAs in CAD patient. The application of platelet miRNAs as predictive markers in overweight/obese individuals may become a marginal milestone in the history of this diet-related disorder treatment.
