A Science Advisory From the American Heart Association, the American College of Cardiology, and the Centers for Disease Control and Prevention
Cardiovascular diseases, including heart disease, hypertension, and heart failure, along with stroke, continue to be leading causes of death in the United States (1,). Hypertension currently affects nearly 78 million∗
∗ The estimate is based on the hypertension definition of blood pressure reading ≥140/90 mm Hg, current use of antihypertensive medications, or being told about having hypertension on 2 occasions by a healthcare provider. When the third component of the definition is excluded, the estimated number of prevalence cases among U.S. adults would be 67 million (3).
adults in the United States and is also a major modifiable risk factor for other cardiovascular diseases and stroke 1. According to data from the National Health and Nutrition Evaluation Survey (NHANES) in 2007 to 2010, 81.5% of those with hypertension are aware they have it, and 74.9% are being treated, but only 52.5% are under control, with significant variation across different patient subgroups (1,4,5,6,7). Of those with uncontrolled hypertension, 89.4% reported having a usual source of health care, and 85.2% reported having health insurance (3). This is the current status, despite the fact that therapies to lower blood pressure and associated risks of cardiovascular events and death have been available for decades, and various education and quality improvement efforts have been targeted at patients and healthcare providers.
