Trial summary

Background: Emerging data favors aortic blood pressure (BP) over brachial cuff BP in predicting CV and renal complications, as this BP directly impacts the heart, brain and kidneys. In parallel, central BP measuring devices have been developed that are more accurate towards aortic BP and easy to use without training. Read more about this study

About this study

Background: Emerging data favors aortic blood pressure (BP) over brachial cuff BP in predicting CV and renal complications, as this BP directly impacts the heart, brain and kidneys. In parallel, central BP measuring devices have been developed that are more accurate towards aortic BP and easy to use without training. In no other condition than advanced chronic kidney disease (CKD) is BP control as important, since undertreatment is associated with adverse CV events and progression towards end-stage kidney disease (ESKD), while overtreatment similarly leads to adverse CV events and injurious falls but also acute kidney injury which can precipitate ESKD. To this day, standard BP management relies on brachial cuff BP, which is an imprecise surrogate marker of aortic BP, more so in the advanced CKD population. Considering that these patients have a high risk of CV morbidity and mortality and is a group where brachial BP may be the least reliable, it can be beneficial to manage hypertension in this population using central BP measurements. With the development of affordable and easy to use central BP devices, routine use of central BP in hypertension would now become a reality. However, the superiority of central BP to traditional brachial cuff BP in regard to clinical outcomes will first need to be demonstrated.

Objectives: To demonstrate that targeting central BP in advanced CKD patients as opposed to brachial cuff BP is feasible and results in lower arterial stiffness after 12 months of follow-up.

Methods: The CENTRAL-CKD trial is an investigator-initiated prospective parallel-group 1:1 randomized double-blinded multicenter pragmatic pilot trial. Patients with CKD stages 4 and 5 (n=116) will be randomized to either a central systolic BP target < 130 mmHg (intervention) or brachial systolic BP target < 130 mmHg (standard care). Central and brachial BP will be concomitantly measured, with treating physicians, patients and investigators blinded towards allocation. As this trial is of a pragmatic design, all other aspects of BP and CKD management, including anti-hypertensive treatment-related decisions, diastolic BP targets, and clinical and laboratory follow-ups will be at the discretion of the attending Nephrologist. The primary outcomes include feasibility of large-scale trial using prespecified criteria and aortic stiffness (carotid-femoral pulse wave velocity) at 12 months. Other cardiovascular, renal, quality of life and safety outcomes will be evaluated.

Importance: CENTRAL-CKD is designed as a pilot trial aimed at providing the framework and justification to proceed to a large-scale trial with adequate power to detect the impact of the proposed intervention on clinically important outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Participants will be randomized to either a central BP target (intervention) or a brachial BP target (standard care). For each group, the source of the BP (central or brachial) will be blinded and only the BP values will be provided to the attending Nephrologist. In both cases, the target SBP will be <130 mmHg.
