Intensive systolic blood pressure (SBP) treatment outcomes were similar between groups of patients with prediabetes and with normal fasting blood glucose levels, according to research presented at the American Diabetes Association (ADA) 77th Scientific Sessions, held June 9-13 in San Diego, California.

Researchers performed a subgroup analysis of participants from SPRINT (Systolic Blood Pressure Intervention Trial; ClinicalTrials.gov identifier: NCT01206062) to examine the effect of intensive vs standard SBP therapy on either the primary outcome or all-cause mortality among participants with prediabetes vs participants with normal fasting blood glucose levels.

 

Within the subgroup analysis, 3898 patients had prediabetes (fasting blood glucose ≥100 mg/dL) and 5425 patients had normal fasting blood glucose levels (<100 mg/dL). During a median 3.3 years follow-up, the hazard ratio (HR) for the primary outcome (a composite of nonfatal acute coronary syndrome, stroke, heart failure, or cardiovascular disease death) was 0.83 (95% CI, 0.66-1.03) vs 0.69 (95% CI, 0.53-0.89; P interaction =.30) for participants with normal fasting blood glucose levels and prediabetes, respectively; HRs for all-cause mortality were 0.71 (95% CI, 0.54-0.94) and 0.77 (95% CI, 0.55-1.06; P interaction =.74), respectively.

“In SPRINT, the beneficial effects of SBP control were similar among those with baseline [fasting blood glucose] <100 and ≥100 mg/dL,” the researchers concluded.
