3. ACCORD Study Design Independently tested 3 strategies to reduce CVD in diabetic patients BP question: does a therapeutic strategy targeting systolic blood pressure (SBP) <120 mm Hg reduce CVD events compared to a strategy targeting SBP <140 mm Hg in patients with Type 2 diabetes mellitus (T2DM) at elevated risk for CVD events? Primary outcome was a composite of CVD death, non-fatal MI and non-fatal stroke adjudicated by a blinded M&M committee BP Trial randomized 4733 participants at 77 sites in US & Canada Cushman WC et al. Am J Cardiol. (2007)

4. ACCORD BP Trial Eligibility Stable Type 2 Diabetes >3 months HbA1c 7.5% to 11% (or <9% if on more meds) High CVD risk = clinical or subclinical disease or >2 risk factors Age (limited to <80 years after Vanguard) ≥ 40 yrs with history of clinical CVD (secondary prevention) ≥ 55 yrs otherwise Systolic blood pressure 130 to 160 mm Hg (if on 0-3 meds) 161 to 170 mm Hg (if on 0-2 meds) 171 to 180 mm Hg (if on 0-1 meds) Urine protein <1.0 gm/24 hours or equivalent Serum Creatinine <1.5 mg/dl Cushman WC et al.

6. ACCORD BP Trial Results With an average follow-up of 4.7 years, the ACCORD BP Trial found a non-significant reduction in major CVD events (HR=0.88, p=0.20, 95% CI 0.73-1.06). Two pre-specified secondary outcomes, non-fatal stroke (HR=0.63, p=0.03, 95% CI 0.41-0.96) and total stroke (HR=0.59, p=0.01, 95% CI 0.39-0.89), showed significant reductions that were consistent with other BP treatment trials. Post-hoc analysis suggested that intensive BP or intensive glycemia treatment alone improved major CVD outcomes by 26% compared with combined standard treatment. There was, however, no additional benefit from combining the two intensive therapies. Cushman et al, NEJM (2010) Margolis et al, Diabetes Care (2014)

7. ACCORDION BP 3957 (87%) surviving ACCORD BP Participants consented to post-trial follow-up of up to 60 months Phone or clinic contacts every 6 months for CVD event follow-up 3 clinic visits 24-30 months, 36-48 months, and 54-60 months after trial close-out Event classification based on clinician interpretation of medical records, without adjudication Analyses used intent to treat approach that included all randomized participants. Time until first event after randomization Participants who declined or died of non-CVD causes were censored as of the last date data were available.

13. ACCORDION BP Conclusions In patients with T2DM at increased CV risk, 4.9 years of intensive BP lowering did not reduce the rate of a composite of fatal and non-fatal major CV events or mortality over a median follow-up of 8.8 years. However, with long term follow-up, a significant interaction between BP and glycemia interventions was observed, with evidence of benefit for intensive BP lowering in participants randomized to standard glycemia therapy (HR=0.79, 95% CI 0.65 – 0.96). The stroke benefit observed during the active intervention did not persist after BP differences waned. This finding adds evidence that the BP-stroke relationship observed during ACCORD was real.
