The cohort was re-examined to obtain ECGs, blood lipid fractions not previously measured, and fibrinogen, as well as upper and lower extremity blood pressures, urine specimens, and medical records. This provided information about silent infarctions and other cardiographic abnormalities as well as previously doctor-diagnosed macrovascular events in long-term survivors of Type 1 diabetes. Study examinations were performed in a mobile van. Participants provided two urine specimens for determination of urinary albumin excretion. Fasting blood was obtained for determination of glycosylated hemoglobin A1c, blood sugar, serum cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, LDL particle size, serum creatinine, and fibrinogen. Additional study procedures included measurements of weight and height, waist and hip girth, and brachial and ankle blood pressures. Electrocardiography was also performed. A questionnaire was administered. Participants were subsequently interviewed yearly and clinical and hospital records and death certificates were collected to document new cardiovascular disease events.
