High blood pressure, defined as systolic blood pressure (SBP) of 140 mmHg or higher or diastolic blood pressure (DBP) of 90 mmHg or higher, is one of the most important risk factors for cardiovascular diseases and chronic kidney disease. Blood pressure is a multifaceted trait, affected by nutrition, environment, and behavior throughout the life course, including fetal and early childhood nutrition and growth, adiposity, specific components of the diet, especially sodium and potassium intakes, alcohol use, smoking, physical activity, air pollution, lead, noise, psychosocial stress, and the use of blood pressure-lowering drugs.

Improving the effective coverage of treatment for patients with hypertension is an objective of many global and regional initiatives, such as HEARTS in the Americas, and national programs for hypertension prevention and control. To achieve this objective, comparable data on hypertension treatment cascade, including the prevalence of hypertension detection, treatment, and control are key to learning from good practice to guide health system programs.

This visualization presents consistent national and regional estimates of the prevalence of hypertension, detection (awareness), treatment, and control from 1990 to 2019 for the Region and 36 countries of the Americas. These data allow for assessing which countries have high versus low detection, treatment, and control rates, and how these metrics have changed over time.
