About this study

Official title: Intensive Management of Blood Pressure and Cholesterol in Elderly Chinese With Hypertension and Atrial Fibrillation (IMPRESSION)

  1. Study name: Intensive management of blood pressure and cholesterol in elderly Chinese with hypertension and atrial fibrillation (IMPRESSION)
  2. Medicine: amlodipine/atorvastatin (5/10mg tablet); amlodipine/atorvastatin (5/20mg tablet); allisartan (240mg/tablet).
  3. Rationale: controlling blood pressure and cholesterol are both effective means to reduce cardiovascular risks, however, it is still unknown whether high cardiovascular risk patients with atrial fibrillation would benefit from intensive management of blood pressure and cholesterol.
  4. Objective: To evaluate the efficacy and safety of intensive management of blood pressure and cholesterol.
  5. Study design: This study is a multi-center, randomized and controlled clinical trial with four equally sized treatment groups: amlodipine/atorvastatin (5/10mg tablet); amlodipine/atorvastatin (5/20mg tablet); amlodipine/atorvastatin (5/10mg tablet)+allisartan (240mg/tablet); amlodipine/atorvastatin (5/20mg tablet)+allisartan (240mg/tablet).
  6. Study population: Men and Women aged over 65 years (n=1200) meeting the inclusion/exclusion criteria.
  7. Randomization and treatment: After stratification by centers, eligible patients will be randomly divided into four groups, taking amlodipine/atorvastatin (5/10mg tablet) once a day or amlodipine/atorvastatin (5/20mg tablet) once a day or amlodipine/atorvastatin (5/10mg tablet)+allisartan (240mg/tablet) once a day or amlodipine/atorvastatin (5/20mg tablet)+allisartan (240mg/tablet) once a day.
  8. Follow up: 3 years.
  9. Sample size: a total of 1200 patients should be enrolled in the combination.
  10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in September 2019, recruitment will start. Patients enrollment will be performed between November 2019 to November 2020. All patients should be followed up before December 2023.

  2. Medicine: amlodipine/atorvastatin (5/10mg tablet); amlodipine/atorvastatin (5/20mg tablet); allisartan (240mg/tablet).
  3. Rationale: controlling blood pressure and cholesterol are both effective means to reduce cardiovascular risks, however, it is still unknown whether high cardiovascular risk patients with atrial fibrillation would benefit from intensive management of blood pressure and cholesterol.
  4. Objective: To evaluate the efficacy and safety of intensive management of blood pressure and cholesterol, especially in hypertensive patients with atrial fibrillation.
  5. Study design: This study is a multi-center, randomized and controlled clinical trial with four equally sized treatment groups: amlodipine/atorvastatin (5/10mg tablet); amlodipine/atorvastatin (5/20mg tablet); amlodipine/atorvastatin (5/10mg tablet)+allisartan (240mg/tablet); amlodipine/atorvastatin (5/20mg tablet)+allisartan (240mg/tablet).
  6. Study population: Men or women aged over 65 years (n=1200) will be screened for atrial fibrillation. Atrial fibrillation patients who never took antihypertensive drugs or stop antihypertensive drugs for more than 2 weeks with systolic blood pressure of 140-179 mmHg and / or diastolic blood pressure of 90-109 mmHg or who is on monotherapy for at least 2 weeks with systolic blood pressure of 140-179 mmHg and / or diastolic blood pressure of 90-109 mmHg will be recruited. Before randomization, two visits should be performed and 6 clinic blood pressures should be recorded. The average of the 6 clinic blood pressures should be 140-179 mmHg in systolic and/or 90-109 mmHg in diastolic. Regardless of whether the office blood pressure meets the enrollment conditions, a one-week home blood pressure measurement should be performed before randomization. Patient should sign the written consent form before screening and be able to go to the clinic by him/herself. Exclusion criteria included: suspected or confirmed secondary hypertension; history of coronary heart disease, myocardial infarction, heart failure, stroke or dementia; taking other drugs that might affect blood pressure; liver dysfunction, serum creatinine ≥1.5 mg/dL (133 μmol/L), urine protein positive; serum potassium >5.0 mmol/L or <3.5 mmol/L; uncontrolled diabetes (HbA1c >8%); BMI ≥35kg/m²; elderly care patients; or patients who are participating in other clinical trials.
  7. Randomization and treatment: After stratification by centers, eligible patients will be randomly divided into four groups, taking amlodipine (5 mg/tablet)+ once a day or amlodipine besylate tablets (5 mg/tablet) + hydrochlorothiazide tablets (25 mg/tablet) once a day.
  8. Follow up: Sitting office blood pressures and electrocardiogram should measured by an OMRON device. Medical history should be recorded. Clinical examinations including home blood pressure, electrocardiogram, blood and urine routine tests and biochemical tests should be performed. Patients should be followed up every three months. Before the follow-up, patients should perform a one-week home blood pressure monitoring.
  9. Sample size and statistical analysis: At least 300 eligible patients should be enrolled in each group, and a total of 1200 patients should be enrolled in total. Data will be analyzed by using the SAS software. ANOVA will be used to compare the parameters between groups and the difference between the four groups with the calculation of 95% confidence interval. In addition, a covariance analysis will also be used in the analysis of baseline parameters.
  10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in September 2019, recruitment will start. Patients enrollment will be performed between October 2019 to October 2020. All patients should be followed up before December 2023. Database construction and statistical analysis will be conducted at the same time, appropriate domestic and international conferences will be selected to publish the research results. The main results will be published in international professional medical journals.
  11. Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Amlodipine/Atorvastatin 5 Mg-20 Mg ORAL TABLET, Amlodipine/Atorvastatin 5 Mg-10 Mg ORAL TABLET and Allisartan Isoproxil in people with Atrial Fibrillation and Hypertension, run by Shanghai Jiao Tong University School of Medicine at 1 site in China.

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 2 inclusion and 1 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: under way, not looking for participants, as of the sponsor's last update on 13 Aug 2025. 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 China. 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.

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?

This study is still under way. Results are not available in the source record yet.

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?

Combined cardiovascular end-point events (time frame: 3 years). 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 13 Aug 2025.
