The hypothesis that three measures of target organ damage in type 2 diabetics would be more closely related to blood pressure (BP) than to glycemic factors was tested by recording 24‐hour ambulatory BP and glycosylated hemoglobin. The prevalence of silent cerebral infarcts with brain magnetic resonance imaging, left ventricular mass index with cardiac ultrasonography, and albuminuria in 244 asymptomatic diabetics (mean age, 65.4±9 years; 122 men and 122 women; hypertension, 73%) were evaluated. Multivariate analysis showed that age (standard partial regression coefficient: β=0.299; p <0.001), duration of hypertension (β=0.176; p =0.007), and 24‐hour systolic BP (β=0.195; p =0.004) were significantly associated with the number of silent cerebral infarcts, but glycosylated hemoglobin (β=0.104; p =0.109) and duration of diabetes were not. Left ventricular mass index was associated with 24‐hour systolic BP (β=0.377; p <0.001) and male sex (β=0.172; p =0.019). Presence of albuminuria was significantly associated with 24‐hour systolic BP (β=0.209; p =0.003), duration of diabetes (β=0.154; p =0.022), cholesterol (β=0.132; p =0.042), and insulin use (β=0.150; p =0.026). In conclusion, all three measures of target organ damage were related to 24‐hour BP, but only albuminuria was related to glycosylated hemoglobin in type 2 diabetics. BP may be more important than glycemic factors for predicting future cardiovascular complications
