Abstract
Expert consensus guidelines recommend antihypertensive treatment to lower secondary stroke risk, but patterns and predictors of blood pressure (BP) treatment and control among stroke survivors in the United States remain unknown. Understanding predictors of poor control can facilitate development of targeted strategies. We reviewed the prevalence and control of hypertension among adults 40 years or older with self-reported stroke who participated in the National Health and Nutrition Examination Surveys 1999-2004 with mortality follow-up through 2006. Predictors of poorly controlled BP (>140/90 mm Hg) and nontreatment were determined via logistic regression. Independent association between antihypertensive use and mortality was determined using Cox models. Among 9145 participants, 490 reported previous stroke; 72% had known hypertension, 8% had undiagnosed hypertension, and 47% had poorly controlled BP. In multivariable analyses, age (odds ratio [OR] per year 1.06, 95% confidence interval [CI] 1.03-1.09), female sex (OR 1.70, 95% CI 1.12-2.57), non-Mexican Hispanic ethnicity (OR 4.54, 95% CI 1.76-11.70), black race (OR 3.15, 95% CI 1.59-6.25), hypercholesterolemia (OR 2.46, 95% CI 1.44-4.21), and diabetes (OR 1.96, 95% CI 1.16-3...Continue Reading
