Insights
Blood pressure remains uncontrolled in many high-risk patients despite standard therapy. This highlights the need for new invasive treatments to manage hypertension effectively in these individuals.
Area of Science:
- Cardiology
- Hypertension Research
- Clinical Trials
Background:
- Hypertension is a significant modifiable risk factor for cardiovascular events.
- High-risk patients may benefit from novel invasive treatment options.
- Assessing current treatment efficacy in high-risk populations is crucial.
Purpose of the Study:
- To determine the prevalence of uncontrolled ambulatory blood pressure (ABP) in high-risk hypertensive patients on routine therapy.
- To evaluate the proportion of patients not meeting guideline-recommended ABP targets.
Main Methods:
- Single-center, cross-sectional study at Erasmus University Medical Center.
- Inclusion of patients aged 18-80 years with hypertension and high cardiovascular risk.
- Standardized office blood pressure (OBP) and 24-hour ABP measurements were performed.
Main Results:
- 41.8% of patients did not meet ESC/ESH 24-h ABP targets; 52.7% did not meet OBP targets.
- 59.3% did not meet ACC/AHA 24-h ABP targets; 79.1% did not meet OBP targets.
- Patients were on a median of 2.0 Defined Daily Doses of antihypertensive drugs.
Conclusions:
- A substantial proportion (40-60%) of high-risk hypertensive patients have uncontrolled blood pressure despite guideline-recommended therapy.
- These findings underscore the need for research into novel invasive blood pressure-lowering treatments.
- Current therapies may be insufficient for achieving optimal blood pressure control in this patient group.
Introduction:
Hypertension is a modifiable risk factor in patients at the highest risk for cardiovascular events. New invasive treatment options are becoming available that might be particularly appealing for high-risk patients. Therefore, the aim of this study was to determine the prevalence of high-risk patients on routine therapy that do not meet guideline recommended ambulatory blood pressure (ABP) targets.
Methods:
This single-center, cross-sectional study was conducted at the Erasmus University Medical Center (Rotterdam, The Netherlands). Inclusion criteria were: (1) age 18-80 years, (2) drugs prescribed for hypertension or history of hypertension and (3) high cardiovascular risk as defined according to the European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines. Patients underwent standardized office blood pressure (OBP) and same-day 24-h ABP measurements. Blood pressure (BP) control was defined according to the 2018 ESC/ESH and 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines.
Results:
A total of 100 patients were enrolled (median age 71 years, 35% female). Mean OBP was 142.2/81.9 ± 18.6/12.6 mmHg and mean 24-h ABP was 126.1/70.1 ± 14.3/9.2 mmHg. Patients were on 2.0 [25th-75th percentile: 1.0-3.3] Defined Daily Doses of antihypertensive drugs. ESC/ESH guideline 24-h ABP and OBP targets were not met in 41.8% (95%CI: 31.5-52.6%) and 52.7% (95%CI: 42.0-63.3%), respectively. ACC/AHA guideline 24-h ABP and OBP targets were not met in 59.3% (95%CI: 48.5-69.5%) and 79.1% (95%CI: 69.3-86.9%), respectively.
Conclusions:
BP remains uncontrolled in 40-60% of high-risk hypertensive patients despite routine use of guideline-recommended therapy. Our findings support the search towards novel invasive BP lowering treatment options.

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.
