Methods 125 NIDDM patients and 50 healthy individuals were selected randomly. Polymerase chain reaction was used to determine their ApoE genotypes. Results The prevalence of ∈3/3 in any vascular complication group was 59.3%, which was significantly lower than 76.0% in controls (P<0.05). The prevalences of ∈3/3, ∈4/3 and ∈4 in coronary heart disease (CHD) group were 51.8%, 33.9% and 20.5%, respectively, which were significantly lower (∈3/3, P<0.01 ) or higher (∈4/3, P<0.01; ∈4, P< 0.05 ) than those in the controls, respectively. The ∈4 frequency was significantly lower in the elderly than in the non elderly group of NIDDM (P<0.05). Conclusion ∈4 increases the risk for vascular complications, especially CHD, and ∈4 may affect the life expectancy of NIDDM patients.展开更多
