intensive management of blood pressure and cholesterol in elderly chinese with hypertension and atrial fibrillation

Conditions: Atrial Fibrillation; Hypertension

Summary: 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.
