The BBB study: a prospective randomized study of intensified antihypertensive treatment. The BBB study group
Insights
The Blood Pressure Lowering in Treated Hypertension study investigated intensifying treatment to reduce diastolic blood pressure to 80 mmHg. Further reductions in diastolic blood pressure may decrease hypertension-related mortality and morbidity.
Area of Science:
- Cardiology
- Clinical Trials
- Public Health
Background:
- Hypertension management remains a critical public health concern.
- Optimizing antihypertensive treatment strategies is essential for reducing cardiovascular risks.
- The clinical significance of further lowering diastolic blood pressure in treated patients requires investigation.
Purpose of the Study:
- To determine if diastolic blood pressure can be reduced to ≤80 mmHg in treated hypertensive patients through intensified therapy.
- To assess whether intensified treatment increases the incidence or severity of side effects.
- To evaluate if further diastolic blood pressure reduction leads to decreased hypertension-associated mortality and morbidity.
Main Methods:
- A multicentre, prospective, randomized trial involving treated hypertensive patients aged 45-67 years with diastolic blood pressure of 90-100 mmHg.
- Patients were allocated to either unchanged or intensified antihypertensive treatment.
- The primary aim was to lower diastolic blood pressure to ≤80 mmHg.
Main Results:
- The study is designed to enroll approximately 2000 patients.
- The trial duration is planned for 3 years to address the primary research questions.
- Data collection and analysis are ongoing to determine treatment efficacy and safety.
Conclusions:
- The Blood Pressure Lowering in Treated Hypertension (BBB) study aims to provide crucial data on intensive blood pressure management.
- Findings will inform clinical guidelines on optimizing antihypertensive therapy for better patient outcomes.
- The study's results are anticipated to impact the management of hypertension and its associated complications.
Abstract:
The BBB study is a multicentre trial designed to investigate three aspects of antihypertensive treatment of great clinical importance: (1) Is it possible to lower diastolic blood pressure further in treated hypertensive patients (to less than or equal to 80 mmHg) through intensified therapeutic activities? (2) Can this aim be fulfilled without increasing the incidence or severity of side effects to unacceptable levels? (3) If 1 and 2 are answered in the affirmative, will the reduction in diastolic blood pressure give a further reduction in hypertension-associated mortality and morbidity? The BBB study is a prospective trial in which male and female treated hypertensive patients, aged 45-67 years, with treated diastolic blood pressures in the range 90-100 mmHg, will be randomly allocated to either unchanged antihypertensive treatment or intensified treatment with the aim of lowering the diastolic blood pressure to less than or equal to 80 mmHg. Statistical calculations indicate that approximately 2000 patients studied for 3 years will be needed to answer the third question. For this reason the trial will be conducted as a multicentre study performed mainly by primary health care physicians.
