About this study

Official title: A Randomized, Double-blind, Active-controlled Study to Assess the Effect of Rosuvastatin on Coronary Flow Reserve in Hypertensive Patients With Cardiovascular Risk

Investigators recently demonstrated that coronary flow reserve (CFR) significantly improved after rosuvastatin therapy in hypertensive patients with average levels of serum cholesterol by measuring the change in CFR after 1 year treatment with rosuvastatin in the RESERVE (Rosuvastatin Effect on Coronary Flow Reserve in Hypertensive Patients) I trial. However, the absence of a placebo group made it difficult to exclude the possibility that lifestyle modification and antihypertensive medication also played a role in improving CFR in our previous study. In a double-blind, randomized trial, investigators try to examine the hypothesis that rosuvastatin added to lifestyle modification will be superior to lifestyle modification alone in improving CFR in hypertensive patients .

Read the detailed description

Statin therapy improves coronary flow reserve (CFR) and decreases cardiac morbidity and mortality in patients with coronary artery disease (CAD) and hypercholesterolemia via pleiotropic effects of statins, including regression of atheroma, stabilization of atherosclerotic plaques. Lipid lowering with a statin also provided beneficial effects in hypertensive patients with average levels of serum total cholesterol in the Anglo-Scandinavian Cardiac Outcomes Trial-Lipid Lowering Arm (ASCOT-LLA). Improvements in endothelial dysfunction and CFR may be related to the beneficial effects of statins in hypertensive patients without hypercholesterolemia.

Previously CFR could be invasively measured using a Doppler guide wire in a cardiac catheterization laboratory, but recent advances in echocardiographic imaging techniques have made it feasible to measure CFR noninvasively in patients without CAD, which highly correlates with the CFR measured by invasive means.Accordingly, investigators recently demonstrated that CFR significantly improved after rosuvastatin therapy in hypertensive patients with average levels of serum cholesterol by measuring the change in CFR after 1 year treatment with rosuvastatin and also found a weak correlation between the change of CFR and the change of LDL cholesterol in the RESERVE (Rosuvastatin Effect on Coronary Flow Reserve in Hypertensive Patients) I trial. However, this trial could not include placebo-control group due to the limited study budget. Although CFR was measured by blinded, batch reading of stored echocardiographic images, bias in measurement might affect the result. In our previous study, study patients continued taking their antihypertensive medications and were educated to follow lifestyle modification during the study period, which may have influenced the change in CFR during follow-up, and the absence of a placebo group made it difficult to exclude the possibility that lifestyle modification and antihypertensive medication also played a role in improving CFR. Investigators hypothesize that rosuvastatin added to lifestyle modification will be superior to lifestyle modification alone in improving CFR in controlled hypertensive patients with cardiovascular risk, and try to examine this hypothesis in a double-blind, randomized comparison study using echocardiography.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Rosuvastatin and Life style modification in people with Hypertension, run by Asan Medical Center at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 14 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 13 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Difference of Coronary flow velocity reserve (time frame: 1 year follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02482207, which also lists 1 linked publication.

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 13 Jan 2021.
