Brief Summary
Atrial fibrillation (AF) is a serious public health problem because of its increasing incidence and prevalence in the aging population. AF is associated with elevated risks of death, stroke, coronary ...
Detailed Description
The CRAFT trial will include approximately 1675 AF patients with home SBP 125-154 mmHg and at least another cardiovascular risk factor. The trial aims to compare the effects of randomization to a trea...
Eligibility Criteria
Inclusion
- Screening and Run-in Assessment
- All patients with documented AF (paroxysmal, persistent) and standard office SBP 140-179 mmHg if not on BP-lowering drugs or 125-164 mmHg with BP-lowering drugs, will be screened for inclusion into the run-in assessment phase.
- The run-in assessment is for 2 weeks. In the run-in phase, patients should be treated according to guideline recommendation, with combined antihypertension agents. Patients should also be guided to measure and upload HBPM measurements correctly. BP measurements (3 readings in the morning and 3 readings in the evening) are required to be uploaded every day for a week before the end of run-in assessment. Patients with average home SBP 125-154 mmHg during the run-in assessment are considered eligible for study inclusion. If home SBP ≥155 mmHg or \<125 mmHg at the time of run-in assessment, another 2 weeks run-in phase can be extended, during which time antihypertensive drugs can be titrated according to the BP lowering algorithm used in this study.
- Inclusion Criteria
- Adults, ≥18 years old
- Documented AF: persistent atrial fibrillation or at least two episodes of intermittent atrial fibrillation in the previous 6 months.
- Home SBP 125-154 mmHg, defined as average of all SBP readings (at least 3 readings 1 min apart in the morning before taking antihypertensive drugs and evening before going to sleep) during the run-in assessment.
- One or more cardiovascular risk factors: (1) Prior history of thromboembolism: defined as any of the following criteria: a) ischemic stroke; b) transient ischemic attack (TIA); c) systemic embolism (SE); (2) Diabetes mellitus (DM): defined as any of the following criteria: a) use of oral hypoglycemic drugs or insulin; b) random blood glucose values ≥11.1 mmol/L in the presence of classic symptoms of hyperglycemia; c) fasting plasma glucose values ≥7.0 mmol/L; d) two-hour plasma glucose values ≥11.1 mmol/L during an oral glucose tolerance test; e) HbA1C values ≥6.5%; (3) Coronary artery disease or Peripheral artery disease: defined as any of the following criteria: a) Previous myocardial infarction (MI), percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), carotid endarterectomy (CE), carotid stenting; b) Peripheral artery disease (PAD) with revascularization; c) Acute coronary syndrome with or without resting ECG change, ECG changes on a graded exercise test, or positive cardiac imaging study; d) At least a 50% diameter stenosis of a coronary, carotid, or lower extremity artery; e) Abdominal aortic aneurysm ≥5 cm with or without repair; (4) Chronic kidney disease (CKD): defined as estimated glomerular filtration rate (eGFR) 30-59ml/min/1.73m2 based on the latest lab value within the past 6 months; (5) Age ≥65 years old
- Exclusion Criteria
- Successful AF ablation (no documented recurrence of AF, atrial flutter, or atrial tachycardia lasting \>30s)
- Moderate-to-severe mitral stenosis, or mechanical heart valve replacement
- Home SBP ≥145 mmHg while already taking ≥4 full dose BP lowering agents, indicating resistant hypertension or poor adherence.
- Unable to upload home BP readings for at least 5 days during the run-in assessment.
- An indication for a specific BP lowering medication (e.g., beta-blocker following acute myocardial infarction) that the person is not taking, without evidence of intolerance. The screenee should be on the appropriate dose of such medication before assessing whether he/she meets the CRAFT inclusion criteria.
- Known secondary cause of hypertension that causes concern regarding safety of the protocol.
- One minute standing SBP \< 110 mm Hg. Not applicable if unable to stand due to wheelchair use.
- Diagnosis of polycystic kidney disease
- Glomerulonephritis treated with or likely to be treated with immunosuppressive therapy
- eGFR \<30 mL/min/1.73m2 or end-stage renal disease (ESRD)
- Cardiovascular event or procedure (as defined above as Coronary artery disease or Peripheral artery disease for study entry) or hospitalization for unstable angina within last 3 months
- Heart failure with reduced left ventricular ejection fraction (\< 40%), or New York Heart Association Class III-IV
- Individuals who have been previously diagnosed with dementia by their physicians
- A medical condition likely to limit survival to less than 3 years, or a cancer diagnosed and treated within the past two years that, in the judgment of clinical study staff, would compromise a participant's ability to comply with the protocol and complete the trial.
- Any factors judged by the investigator to be likely to limit adherence to interventions. For example, active alcohol or substance abuse, significant memory or behavioural disorder.
- Currently participating in another clinical trial (intervention study). Note: Patient must wait until the completion of his/her activities or the completion of the other trial before being screened for CRAFT.
- Living in the same household as an already randomized CRAFT participant
- Any organ transplant
- Unintentional weight loss \> 10% in last 6 months
- Pregnancy, currently trying to become pregnant, or of child-bearing potential and not using birth control
