Insights
Many patients adhere to hypertension treatment, yet blood pressure control remains inadequate. This highlights a gap in managing systemic arterial hypertension (SAH) despite patient compliance.
Area of Science:
- Cardiology
- Public Health
- Hypertension Management
Background:
- Systemic arterial hypertension (SAH) is a significant cardiovascular risk factor with often insufficient blood pressure (BP) control.
- Assessing adherence to antihypertensive treatment via 24-hour ambulatory blood pressure monitoring (ABPM) can aid in defining BP control targets.
Purpose of the Study:
- To evaluate adherence to antihypertensive therapy.
- To examine the association between adherence and BP levels measured by 24-hour ABPM.
- To assess hypertension control in primary health care (PHC) settings.
Main Methods:
- Cross-sectional study involving 143 hypertensive patients from PHC centers.
- Adherence assessed using the Morisky-Green test.
- 24-hour ABPM utilized for BP measurement.
Main Results:
- 65.7% of patients showed adherence to treatment; 14% were non-adherent.
- 55.2% of patients achieved controlled hypertension (<130/80 mmHg) based on 24-hour ABPM.
- 44.8% had uncontrolled hypertension, with 72% exhibiting no nocturnal BP dip and 41.9% uncontrolled while awake.
Conclusions:
- Adequate hypertension control was lacking despite good patient adherence to antihypertensive treatment.
- Primary health care professionals missed opportunities to adjust BP control targets effectively.
- Further strategies are needed to improve hypertension management in PHC settings.
Background:
Although systemic arterial hypertension (SAH) is an important cardiovascular risk factor, blood pressure level control often remains inadequate. Assessment of adherence to antihypertensive treatment through 24-hour ambulatory blood pressure monitoring (ABPM) may represent an important aid in the search for BP control targets.
Objective:
To assess adherence to antihypertensive treatment and its association with BP values at 24-hour ABPM in hypertensive patients treated in primary health care (PHC) centers.
Methods:
We carried out a cross-sectional study of 143 hypertensive patients, who constituted a representative sample of patients from PHC centers in the town of Antonio Prado, RS. The Morisky-Green test was used to evaluate adherence and verify the number of medications used by patients, followed by 24-hour ABPM.
Results:
We observed that 65.7% of the sample was considered adherent to the proposed treatment, 20.3% were moderately adherent and only 14% were classified as non-adherent. Considering all the 143 patients evaluated, 79 (55.2%) were identified as having controlled hypertension (<130/80 mmHg) according to the 24-hour ABPM measurements, 64 (44.8%) were considered uncontrolled (>130/80 mmHg), 103 (72%) had absence of nocturnal BP dip and 60 (41.9%) were uncontrolled while awake.
Conclusions:
In this study, we observed a lack of adequate hypertension control with a consequent loss of opportunity for PHC professionals to adequately adjust the recommended BP control targets. This fact occurs in spite of proper adherence to antihypertensive treatment by patients in PHC centers.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
