  • Data are means ± SD. Subgroups based on baseline morning glucose determinations had a similar period of follow-up care after initial laboratory studies. More patients in subgroups with higher glucose had a new diagnosis of heart failure during the period of care (glucose 100–109 or 110–125 compared with <90 mg/dl, P < 0.05). *Percentage of each group that had a new diagnosis of heart failure during their period of care; †time from first laboratory studies until the first diagnosis.
