Insights
High blood pressure (hypertension) affects over 30% of adults in Ecuador. Many with hypertension remain untreated or inadequately treated, highlighting the need for better screening and management strategies.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Arterial hypertension is a significant global health challenge, contributing to millions of deaths annually.
- Cardiovascular diseases, with hypertension as a primary risk factor, were the leading cause of death in Ecuador pre-pandemic.
- The May Measurement Month (MMM) campaign aims to increase awareness and facilitate blood pressure screening.
Purpose of the Study:
- To assess the prevalence of hypertension in Ecuador during the COVID-19 pandemic.
- To evaluate the effectiveness of current hypertension management and control strategies within the screened population.
Main Methods:
- A cross-sectional survey conducted in May 2021 across 22 health centers in Ecuador as part of the MMM21 campaign.
- Standard MMM protocol for blood pressure measurement and hypertension definition (≥ 140/90 mmHg or on medication).
- Statistical analysis included multiple imputation for missing blood pressure readings.
Main Results:
- A total of 1326 volunteers participated; 31.9% (423 individuals) were diagnosed with hypertension.
- Among those with hypertension, 70.5% were on antihypertensive medication, but 50.0% of this group had uncontrolled blood pressure.
- Overall, only 35.2% of participants with hypertension achieved controlled blood pressure levels (<140/90 mmHg).
Conclusions:
- The MMM21 campaign revealed a high prevalence of hypertension in Ecuador, even during the COVID-19 pandemic.
- A substantial proportion of individuals with hypertension are either untreated or inadequately treated, indicating a gap in care.
- Findings underscore the critical need for enhanced screening programs and improved management of hypertension in Ecuador.
Abstract:
Arterial hypertension is a growing burden worldwide, leading to over 10.8 million deaths each year. Before the outbreak of the COVID-19 pandemic, cardiovascular diseases were the main cause of death in Ecuador. Hypertension is the main risk factor for the major cause of death, coronary and cerebrovascular disease. The 2021 May Measurement Month Campaign (MMM21) is a global initiative by the International Society of Hypertension aimed at raising awareness of high blood pressure (BP) and to provide a temporary solution for opportunistic screening until more systematic approaches can be established. A cross-sectional survey was carried out in May 2021 across 22 health centres in Ecuador. The average age of participants was 44.7 ± 15.8 years. Blood pressure measurement, the definition of hypertension (mean of the 2nd and 3rd BP measurements ≥ 140/90 mmHg or on medication for high BP), and statistical analysis followed the standard MMM protocol. In total, 1326 volunteers participated in MMM21. After multiple imputation of missing BP readings, 423 (31.9%) had hypertension. Of those, 70.5% were receiving antihypertensive medication. Of individuals receiving antihypertensive medication, 50.0% had uncontrolled BP. Overall, of 423 participants with hypertension, only 35.2% had their BP controlled (<140/90 mmHg). MMM21 demonstrated a high prevalence of hypertension in Ecuador during the COVID-19 pandemic. It was the largest BP screening campaign done in Ecuador thus far. The high percentage of persons untreated or with uncontrolled hypertension while on pharmacologic treatment suggests that appropriate screening can help to identify a significant number of people with elevated BP and those inadequately treated. These data should attract the attention of doctors and health care providers in Ecuador.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
