Hypertension affects millions, yet many remain undiagnosed or undertreated, leading to inadequate blood pressure control and rising cardiovascular risks. Addressing multifactorial causes is crucial for improving patient outcomes and public health.
Area of Science:
- Cardiovascular Medicine
- Public Health
- Hypertension Research
Background:
- Hypertension is the most common cardiovascular disease in the U.S., impacting 43-50 million adults.
- Despite known risks and effective treatments, many are unaware of their condition, untreated, or inadequately controlled.
- Progress in reducing cardiovascular morbidity and mortality has stalled since the 1990s, with increasing rates of stroke, end-stage renal disease, and heart failure.
Purpose of the Study:
- To investigate the reasons behind the lack of continued progress in hypertension control.
- To identify factors contributing to inadequate blood pressure management in the U.S. population.
Main Methods:
- Review of epidemiological data on hypertension prevalence and control rates.
- Analysis of trends in cardiovascular disease, stroke, renal disease, and heart failure.
- Identification of contributing factors to suboptimal blood pressure management.
Main Results:
- Significant proportions of hypertensive individuals are undiagnosed, untreated, or inadequately controlled.
- Progress in cardiovascular health seen in previous decades has not continued into the 1990s.
- Rising rates of stroke, end-stage renal disease, and heart failure observed.
Conclusions:
- Inadequate blood pressure control stems from multifactorial issues including disease complexity, environmental influences, poor adherence, physician-related factors, and medication side effects.
- Continued public health efforts are needed to improve hypertension diagnosis, treatment, and management.
- Addressing the identified barriers is essential to reverse negative cardiovascular health trends.
Abstract:
Hypertension is by far the most prevalent form of cardiovascular disease in the United States, affecting between 43 million and 50 million adults. Although uncontrolled hypertension is well recognized as a modifiable risk factor associated with long-term target-organ damage, many are unaware they have hypertension, as many as 50% are not receiving treatment, and an estimated 70% of those being treated do not achieve adequate blood pressure control. Why? Despite the effectiveness of antihypertensive therapy and considerable evidence that morbidity and coronary disease have decreased between 1950 and 1990, it appears that the progress made during those decades has not continued into the 1990s. Age-adjusted stroke rates for 1990 to 1994 rose slightly, and the rate of decline in coronary disease during this same period has leveled off. Moreover, both the rate of end-stage renal disease and the prevalence of heart failure increased during the early 1990s. The reasons for inadequate blood pressure control are numerous, including the multifactorial nature of hypertension; the presence of environmental factors such as diet, smoking, and concomitant drug therapy; poor adherence to therapy; insufficient therapeutic effort on the part of the treating physician; and adverse side effects of hypertensive agents.
