Insights
In Venezuela, only 52.6% of hypertensive patients achieved controlled blood pressure. Poor control was linked to comorbidities and treatment non-compliance, highlighting a significant public health concern.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Hypertension (HT) control levels are not well-established in Venezuela.
- Previous large-scale studies on hypertension management are lacking in the region.
Purpose of the Study:
- To determine the prevalence of controlled hypertension among pharmacologically treated patients in Venezuela.
- To identify factors associated with uncontrolled hypertension.
Main Methods:
- A cross-sectional study involving 4,320 patients aged 18 and older.
- Data collection focused on pharmacological treatment and hypertension control status.
Main Results:
- The prevalence of controlled hypertension was 52.6% (95% CI: 51.1-54.1%).
- Uncontrolled hypertension was significantly associated with diabetes, hypertensive heart disease, chronic kidney disease, and peripheral arterial disease.
- Treatment non-compliance was markedly higher in patients with uncontrolled HT (43.2%) compared to controlled HT (5.1%).
Conclusions:
- The study found that 52.6% of hypertensive patients in Venezuela had their condition under control.
- Comorbidities and poor treatment adherence are significant barriers to achieving hypertension control.
Introduction:
In Venezuela, no large studies have been conducted to determine the level of control of hypertension (HT).
Objective:
The primary objective was to know the prevalence of controlled HT among hypertensive patients treated pharmacologically.
Materials And Methods:
A cross-section study was conducted on patients 18years and older.
Results:
A total of 4,320 patients were included. The prevalence of controlled hypertension was 52.6% (95%CI: 51.1-54.1%). The lack of control of HT was associated with diabetes (P<.001), hypertensive heart disease (P<.001), chronic kidney disease (P<.001), and peripheral arterial disease (P=.02). Non-compliance of treatment was also associated with uncontrolled HT (5.1% [117/2,274] in the controlled versus 43.2% [885/2,046] in the uncontrolled; (P<.001).
Conclusion:
The prevalence detected of controlled hypertension was 52.6%.
