Predictors of Hypertension Control in Veterans at the SAVAHCS

Abstract

Objectives: To assess predictors of systolic blood pressure control in the Southern Arizona Veterans Affairs Health Care System. Methods: 6185 patients were followed over a 2 year period and predictors of blood pressure control were examined using univariate and multivariate analyses. Primary independent variables assessed were age, gender, race, antihypertensive medication class, and comorbidities. The primary dependent variable was systolic blood pressure. Results: Sixty percent of patients studied had controlled hypertension. Significant predictors of better blood pressure control were the presence of coronary artery disease, use of loop diuretics, not using miscellaneous antihypertensive agents, lower age, and not of Hispanic descent or not an African-American. Conclusions: Frequency of systolic blood pressure control was found to be higher than previously reported. In contrast, age, sex, and race were significant predictors of control as reported elsewhere. Lastly, coronary artery disease, loop diuretics, and miscellaneous antihypertensive agents were found to be the only other significant predictors of systolic blood pressure control. These results suggest that there is largely no difference between the major antihypertensive medications class with respect to blood pressure control.
