Coronary Artery Disease in South Asian Patients: Cardiovascular Risk Factors, Pathogenesis and Treatments

In the last decades a significant increase of the migratory phenomenon from South Asian coun-tries to the Western World has occurred for social, economic and geopolitical reasons. The aim of this review is to describe cardiovascular risk factors, path-ogenesis and treatments of coronary artery disease in South Asian patients. It is well established that South Asian populations have a higher prevalence of coro-nary artery disease and premature onset of myocardial infarction episodes than other populations. This higher predisposition might be caused by genetic factors, common in both South Asian patients residing in their birth country and in those residing abroad, but it may also be due to the new spatial environment in which they live. It will be important to examine the leading cardiovascular risk factors determining increasing incidence of coronary artery disease in the South Asian population. These include: insulin resistance, hyper-tension, dyslipidaemia and abdominal obesity caused by a diet rich in refined carbohydrates and saturated fats. Furthermore, it is important to examine emerging cardiovascular risk factors strictly related to this par-ticular ethnic group. The evidence of higher levels of prothrombotic and proinflammatory factors, for example lipoprotein(a) and proinflammatory adipo-kines, as well as the influence of air pollution and psy-chosocial stress, may have consequences on the risk, treatment and outcomes of the coronary artery disease in this population. Migrants from South Asia deserve to be addressed and framed with particular care in terms of cardiovascular risk and especially in the man-agement of acute coronary events
