Microalbuminuria is associated with higher cardiovascular morbidity and mortality in Type 2 (non‐insulin‐dependent) diabetic patients. This study was designed to assess whether Type 2 diabetic patients with microalbuminuria (urinary albumin excretion rate (AER) 20–200 μg min −1 ) is associated with alterations in platelet aggregability as compared with those with normal urinary albumin excretion (AER < 20 μg min −1 ). Platelet aggregability was compared between 21 Japanese Type 2 diabetic patients with microalbuminuria and 21 individually pair‐matched (for age, sex, body mass index, treatment, and HbA 1c level) patients with normoalbuminuria. The in vitro platelet aggregation induced by 1.0 and 3.0 μmol I −1 ADP and 0.5 and 1.0 mg I −1 collagen was measured using platelet‐rich plasma. No significant differences were observed between the two groups in the values for maximum percent platelet aggregation, percent aggregation at 3 min, and aggregation velocities after adding ADP or collagen. Microalbuminuric patients had significantly higher mean values for systolic ( p < 0.004) and diastolic ( p < 0.02) blood pressures and plasma fibrinogen level ( p < 0.03) as compared with the respective mean values in normoalbuminuric patients. The results suggest that Japanese microalbuminuric Type 2 diabetic patients do not differ in the degree of platelet aggregability as compared with normoalbuminuric patients, despite an increase in certain other coronary risk factors.
