Many recent studies ascertained that cardiovascular diseases are in first place for cause of mortality worldwide. Atherosclerosis is a chronic and progressive pathology characterized by an initial deposit of lipids inside the inner layer (tunica intima) of an artery and it is the most prominent cardiovascular disease. As the fat accumulation progresses there is the creation of a plaque composed by a lipidic core and a thick fibrous cap. The growth of plaque causes an obstruction of the artery and consequently a drastic change in blood flow. If atherosclerosis affects coronary arteries, it leads to reduction in myocardial perfusion and may evolve in myocardial infarction (MI).
