Objective: To investigate control of risk factors in African American patients with previous stroke.
Methods: The baseline history, physical examination, and laboratory data for 1,086 subjects enrolled in the African American Antiplatelet Stroke Prevention Study from 1995 to 1999 were studied. The level of awareness, pharmacologic treatment, and control of diabetes mellitus (casual plasma glucose level 
200 mg/dL), hypertension (blood pressure 140/90 mm Hg), and hypercholesterolemia (serum total cholesterol level 240 mg/dL) were determined.
Results: Forty percent of subjects reported a history of diabetes mellitus or use of diabetic medication, and 2% of the remaining subjects had a serum glucose level of 200 mg/dL. Of those subjects known to be diabetic, 33% had a serum glucose level of 200 mg/dL. A history of hypertension or use of antihypertensive medication was reported in 87% of subjects, and 48% of the remaining subjects were found to have a blood pressure of 140/90 mm Hg on exam. Of those subjects known to be hypertensive by history, 73% were on antihypertensive medication, but only 30% of the treated subjects had a blood pressure under 140/90 mm Hg. A history of hypercholesterolemia or use of a lipid-lowering agent was reported in 40% of subjects, and 24% of the remaining subjects had a cholesterol level of 240 mg/dL. Use of a lipid-lowering agent was reported in 43% of subjects known to be hypercholesterolemic, and 38% of the hypercholesterolemic subjects had a cholesterol level of 240 mg/dL.
Conclusion: Inadequate rates of awareness and control of cardiovascular disease and stroke risk factors are seen in a clinical trial of African American stroke patients and are comparable with those of previously published reports.
