title: Associations between insulin resistance and thrombotic risk factors in high-risk South Asian subjects.
abstract: OBJECTIVE
  There is recognized association of thrombotic factors to insulin resistance in White Europeans. South Asians are more insulin resistant compared with white Europeans and express increased metabolic features of insulin resistance. The aim of the study was to determine whether there was any relationship between insulin resistance and thrombotic risk factors in healthy South Asian subjects.
  
  
  METHODS
  Healthy South Asians (n = 185) clinically free from ischaemic heart disease, ischaemic stroke or peripheral vascular disease were randomly recruited. Partial correlations of homeostasis model assessment (HOMA) (surrogate of insulin resistance) were analysed with two fibrinolytic and five coagulation factors.
  
  
  RESULTS
  Age and gender-adjusted HOMA was significantly correlated to plasminogen activator inhibitor-1 (0.51, P = 0.0001), tissue plasminogen activator antigen (r = 0.40, P = 0.0001), fibrinogen (r = 0.28, P = 0.0001), von Willebrand factor (r = 0.17, P = 0.03), factor XIIa (r = 0.22, P = 0.006) factor VII antigen (r = 0.19, P = 0.02) and factor XIII B subunit (r = 0.30, P = 0.001).
  
  
  CONCLUSIONS
  Insulin resistance significantly clusters with fibrinolytic and coagulation factors in South Asians, which may contribute to high prevalence of vascular disease in this population.
