Insights
Blood pressure control in hospital referral units remains low at 42%, unchanged for a decade. Despite improved therapeutic efforts, increased patient risk and comorbidities hinder blood pressure management.
Area of Science:
- Cardiology
- Hypertension Management
- Public Health
Context:
- Limited data exists on blood pressure (BP) control in hospital referral settings.
- Primary care BP control is well-documented, but hospital settings remain understudied.
Purpose:
- To assess the degree of BP control in hypertensive patients within hospital referral units.
- To identify factors associated with uncontrolled BP in this population.
Summary:
- A study of 1,550 hypertensive patients found only 42% achieved BP control (below 140/90 mm Hg).
- Uncontrolled BP was linked to female gender, obesity, smoking, left ventricular hypertrophy, and dyslipidemia.
- Therapeutic inertia was noted in 39% of patients with uncontrolled BP.
Impact:
- The findings highlight a persistent challenge in managing hypertension in specialized hospital care.
- Despite advancements, BP control rates have not improved over the last ten years.
- Increased patient risk factors and comorbidities complicate achieving target BP values.
Background And Objective:
Blood pressure (BP) control has been extensively studied in patients attended in primary care but reports in the hospital setting, which includes referral units, are scarce. The aim was to evaluate the degree of BP control in hypertensive patients attended in referral units.
Patients And Methods:
We studied 1,550 hypertensive subjects (41.5% women) with a mean age of 64 (12) years, who were receiving antihypertensive drugs. The degree of BP control was estimated in a single visit by the proportion of patients with BP below 140/90 mm Hg.
Results:
BP was controlled in 653 patients (42%). In comparison, those whose BP was not controlled were more frequently women (odds ratio [OR] 1.57; 95% confidence interval [95%CI]: 1.23-1.99), obese (OR 1.28; 95%CI 1.00-1.63), smokers (OR 1.78; 95%CI 1.36-2.34), had left ventricular hypertrophy (OR 1.86; 95%CI 1.46-2.36) and elevated values of total serum cholesterol (OR 1.50; 95%CI 1.19-1.90) and triglycerides (OR 1.63; 95%CI 1.29-2.07). Therapeutical inertia was observed in 39% of uncontrolled patients. In a subgroup of patients who underwent ambulatory BP monitoring, discordance between measurements was only present in 23% (9.8 with isolated clinic hypertension and 13.1% with masked hypertension).
Conclusion:
The degree of BP control in patients attended in referral units is estimated in 42% and has not been modified in the last decade. Although therapeutical effort and inertia have improved, this only compensates the increased risk and comorbidities of attended patients, making more difficult the control of BP values.

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...
Blood Pressure
Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
