Background It is unclear if achieving multiple risk factor (RF) goals through protocol-guided intensive medical therapy is feasible or improves outcomes in type 2 diabetes (T2DM). Objectives We sought to quantify the relationship between achieved RF goals in the BARI 2D (Bypass Angioplasty Investigation Revascularization 2 Diabetes) trial and cardiovascular events/survival. Methods We performed a nonrandomized analysis of survival/cardiovascular events and control of 6 RFs (nonsmoker, non-HDL-C <130 mg/dl, triglycerides <150 mg/dl, blood pressure [systolic <130 mm Hg; diastolic <80 mm Hg], hemoglobin A1c <7%) in BARI 2D. Cox models with time-varying number of RFs in control were adjusted for baseline number of RFs in control, clinical characteristics, and trial randomization assignments. Results In 2,265 patients (mean age 62 years, 29% women) followed for 5 years, the mean ± SD number of RFs in control improved from 3.5 ± 1.4 out of 6 at baseline to 4.2 ± 1.3 at 5 years, p < 0.0001. The number of RFs in control during the trial was strongly related to death (global p = 0.0010) and the composite of death, myocardial infarction and stroke (global p = 0.0035) in fully adjusted models. Participants with 0 to 2 RFs in control during follow-up had a 2-fold higher risk of death (hazard ratio [HR]: 2.0; 95% CI: 1.3 to 3.3, p = 0.0031) and a 1.7-fold higher risk of the composite endpoint (HR: 1.7; 95% CI 1.2 to 2.5, p = 0.0043), compared with those with 6 RFs in-control. Conclusions Simultaneous control of multiple RFs through protocol-guided intensive medical therapy is feasible and relates to cardiovascular morbidity and mortality in patients with coronary disease and T2DM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
