The difference between mean plasma levels of von Willebrand factor and platelet aggregation in type 2 diabetes mellitus with and without peripheral vascular disease at Sardjito General Hospital, Yogyakarta.

Aim: To determine the differences in mean plasma values of von Willebrand factor and platelet aggregation in type 2 DM patient with or without peripheral arterial disease.

Methods: This is a cross-sectional study, conducted from August to December 2006, in Dr. Sardjito General Hospital Yogyakarta, on type 2 DM patients, aged 50 years and above, and signed the informed consent. The exclusion criteria are cardiac failure, renal insufficiency (creatinine clearance <30 ml/minute), malignancy, acute disease, decrease hepatic function, having ulcer or DM gangrene, amputation, taking multivitamine and/or antiplatelet, and smoking. All samples that matched inclusion criteria were divided into 2 groups: with peripheral arterial disease and without peripheral arterial disease. The data of subjects are presented as mean and standard deviation and proportion. Variables with numeric data are analized with the student t-test for normal distribution and with Mann-Whitney U-test for abnormal distribution. Significancy limit was set at p value of <0,05. Statistical analysis was done by using SPSS 11.5 software.

Results: There were 17 subjects having PVD. There were no significantly differences of mean vWF plasma levels (140.544 + 76,137% vs. 133.325 + 53,246%) and platelet aggregation (87.741 + 19.886% vs. 93.981 + 10.138%) between type 2 DM with and without PVD (p >0.05).

Conclusion: There were no statistically difference in mean vWF plasma levels and platelet aggregation between type 2 diabetes mellitus with and without PVD.
