Results from the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial
OBJECTIVE The aim of this manuscript was to report the risk of incident peripheral arterial disease (PAD) in a large randomized clinical trial that enrolled participants with stable coronary artery disease and type 2 diabetes and compare the risk between assigned treatment arms.
RESEARCH DESIGN AND METHODS The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial randomly assigned participants to insulin sensitization (IS) therapy versus insulin-providing (IP) therapy for glycemic control. Results showed similar 5-year mortality in the two glycemic treatment arms. In secondary analyses reported here, we examine the effects of treatment assignment on the incidence of PAD. A total of 1,479 BARI 2D participants with normal ankle-brachial index (ABI) (0.91–1.30) were eligible for analysis. The following PAD-related outcomes are evaluated in this article: new low ABI ≤0.9, a lower-extremity revascularization, lower-extremity amputation, and a composite of the three outcomes. Read More
