Surveillance and monitoring of cardiovascular risk factors including raised blood pressure are critical to informing efforts to prevent and control cardiovascular disease. Yet, many countries lack the capacity for adequate national surveillance. Furthermore, hypertension indicators are often reported in different ways, which hampers the ability to compare and assess progress. In order to encourage standardized hypertension surveillance reporting, the World Hypertension League assembled an Expert Committee to develop a standard set of core indicators, definitions, and recommended analyses. The recommended core indicators are: (1) blood pressure distribution, (2) prevalence of hypertension, (3) awareness of the condition, (4) antihypertensive drug treatment, and (5) control of hypertension based on drug therapy. Each of these can be reported overall and by age group and sex, with crude and age-standardized changes tracked over time in order to assess the impact of instituted policies and programs for hypertension prevention and control. An expanded list of indicators can also facilitate tracking of hypertension prevention and control efforts. Widespread adoption of these indicators and analyses could benefit all those conducting and analyzing hypertension surveys and will facilitate hypertension surveillance efforts.
