OBJECTIVE—To estimate the absolute and relative risk of cardiovascular disease (CVD) in patients with type 1 diabetes in the U.K.

RESEARCH DESIGN AND METHODS—Subjects with type 1 diabetes (n = 7,479) and five age- and sex-matched subjects without diabetes (n = 38,116) and free of CVD at baseline were selected from the General Practice Research Database (GPRD), a large primary care database representative of the U.K. population. Incident major CVD events, comprising myocardial infarction, acute coronary heart disease death, coronary revascularizations, or stroke, were captured for the period 1992–1999.

RESULTS—The hazard ratio (HR) for major CVD was 3.6 (95% CI 2.9–4.5) in type 1 diabetic men compared with those without diabetes and 7.7 (5.5–10.7) in women. Increased HRs were found for acute coronary events (3.0 and 7.6 in type 1 diabetic men and …
