Purpose of review: Persons with chronic kidney disease (CKD) exhibit a disproportionate burden of elevated blood pressure (BP) with a high prevalence of premature end-stage renal disease and cardiovascular events.
Recent findings: Results of recent randomized controlled clinical trials suggest that most patients with reduced estimated glomerular filtration rate (eGFR) and hypertension experience optimal clinical outcomes when SBP is less than 140 mmHg and DBP is less than 90 mmHg. The benefit of additional lowering of SBP to less than 130 mmHg and DBP to less than 80 mmHg remains controversial, and appears to be of most benefit to the subset of CKD patients with proteinuria (>300 mg/day). The combination of a diuretic and an angiotensin receptor blocker (ARB) or angiotensin-converting enzyme inhibitor (ACEI) has demonstrated particular promise in patients with reduced eGFR and proteinuria.
Summary: A practical approach in clinical practice for the treatment of elevated BP in persons with CKD is to achieve a BP less than 140/90 mmHg with a combination of diuretic and an ARB or ACEI. Consideration for a lower BP goal and other therapeutic and nontherapeutic interventions can be made based on the cause of CKD, presence of proteinuria, or other coexisting medical conditions.
