NCHS Data Brief. 2020 Apr(364):1-8.
Hypertension is a major risk factor for cardiovascular disease. Lowering blood pressure has been shown to decrease the incidences of stroke, heart attack, and heart failure (1,2). This report provides 2017-2018 U.S. hypertension prevalence estimates using the 2017 American College of Cardiology and American Heart Association definition of hypertension (3) and new guidelines, which redefine hypertension by lowering the previous threshold levels of 140/90 mmHg to 130/80 mmHg (4). This change categorizes a greater percentage of people as having hypertension.
高血压是心血管疾病的主要危险因素。降低血压已被证明可降低中风、心脏病发作和心力衰竭的发生率（1,2）。本报告提供了 2017-2018 年美国高血压流行率的估计值，使用了 2017 年美国心脏病学会和美国心脏协会的高血压定义（3）和新指南，这些指南通过将先前的 140/90mmHg 阈值水平降低至 130/80mmHg（4）重新定义了高血压。这一变化将更多的人归类为患有高血压。
