title: [Microalbuminuria, lipid changes and coronary heart disease in non-insulin-dependent diabetics].
abstract: BACKGROUND
  Microalbuminuria could be a possible coronary risk factor:
  
  
  OBJECTIVE
  To study the association between microalbuminuria, serum lipid levels and coronary heart disease in non-insulin-dependent diabetics.
  
  
  METHODS
  We studied 104 non-insulin-dependent diabetics, who were separated in four groups according to the presence of microalbuminuria, defined as a 24 h albumin excretion of 30-300 mg/24 h and according the history of coronary artery disease. Total, HDL and LDL cholesterol, triglycerides, alpha, beta, prebeta lipoproteins, lipoprotein (a), apoproteins A and B were measured in all.
  
  
  RESULTS
  Twenty patients with and 32 without coronary artery disease had normal albumin excretion and the same number of patients had a urinary albumin 30-300 mg/24 h. All four groups were comparable in terms of metabolic control, nutritional status, blood pressure and creatinine levels. Patients with coronary artery disease had higher urinary albumin excretion than patients without the disease 91 (32-173) and 34 (5-97) mg/24 h respectively p < 0.01. Patients with coronary artery disease and microalbuminuria had higher triglycerides, beta, pre beta lipoproteins, Apo B, Lp(a) and lower Apo B and alpha lipoproteins. This group also had a higher frequency of abnormal pre beta and alpha lipoprotein levels, when compared with coronary patients with normal albumin excretion. In coronary patients there was a positive association between urinary albumin levels and triglycerides (r = 0.24), pre beta lipoproteins (r = 0.27) and Apo B (r = 0.3); there was also a negative association with HDL cholesterol (r = 0.25) and alpha lipoproteins (r = -0.41).
  
  
  CONCLUSIONS
  In this group of non-insulin-dependent diabetics, an association among microalbuminuria, abnormal serum lipid levels and coronary artery disease was detected.
