title: [Cardiac syndrome X and insulin resistance].
abstract: OBJECTIVE
  To determine whether there is insulin resistance in patients with syndrome X.
  
  
  METHODS
  By using oral glucose tolerance test (OGTT), plasma glucose and insulin levels, and insulin sensitivity index (ISI) were measured in 11 patients with syndrome X and in 10 sex and age matched normal subjects as controls.
  
  
  RESULTS
  The syndrome X group had a higher fasting insulin level and ISI than the control group (P < 0.05). After oral glucose, plasma insulin level and ISI in patients with syndrome X were significantly higher than the control group (P < 0.01).
  
  
  CONCLUSIONS
  In patients with syndrome X there are hyperinsulinemia and insulin resistance.
