About this study
The aim of this study is to investigate the effect of strict blood pressure control versus conventional care in patients with asymptomatic moderate to severe aortic valve stenosis.
The study is a randomized (1:1), open label, controlled intervention trial.
Hypothesis:
- Strict BP control for 12 months reduces the progression of LV remodelling compared to conventional treatment.
- Strict BP control for 2 years reduces the increase in aortic valve calcification and LV remodelling compared to conventional treatment.
- Strict BP reduction for up to 10 years reduces the need for aortic valve replacement and cardiovascular events compared to conventional care.
- Conditions
- Aortic Valve Stenosis, Hypertension,Essential, Heart Failure
- Being tested
- Blood presssure reduction
- Keywords

- 1\. BP-AVALVE I: 60 patients will be randomized (1:1) to either strict BP control (N=30) or conventional treatment (N=30). Treatment period will be 12 months. 2\. BP-AVALVE II: 200 patients will be randomized (1:1) to either strict BP control as in study 1 (N=100) or conventional care as in study 1 (N=100). Average treatment period will be 2 (1-3) years. 3\. BP-AVALVE III: Patients from BP-AVALVE-II continue in the randomized design until they develop symptoms of AS or have been followed for 10 (7-13) years. Patients will be reexamined at the end of the study period or in case they develop symptoms or LV failure and thus indication of valve replacement. Since the medicinal products used in this study is not the subject of the trial, the Danish Medicines Agency has classified this study as a clinical trial, in which medicinal products are used as a tool to induce a well-known physiological response. Therefor no further approval from the Danish Medicine Agency is required.

Who may be eligible to take part?
The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in LV mass (time frame: Changes will be evaluated after an expected average of 12 months treatment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
