Purpose: To review the progress in hypertension control in the United States since 1972, to examine the factors that contributed to that progress and to consider areas in which further improvement is required. Methods: A review of epidemiological, clinical and health services research related to hypertension control was conducted. We report our experience in evaluating hypertension control in a multi-ethnic community clinic population as an illustration of the challenges of hypertension management in primary care practice. Summary of findings: Hypertension prevalence in the United States population has remained relatively stable, whereas actual blood pressure levels in the population have declined slightly. Most Americans (approximately 80%) have had a blood pressure check within the past year, but the rate of blood pressure control in treated hypertensives has been disappointing. The current diagnostic and therapeutic criterion of blood pressure less-than-or-equal-to 140/90 mmHg, regardless of individual patient characteristics (e.g. age, race), should be re-evaluated.
