Target Blood Pressure: <130/80 mmHg (Answer: C)
For a 55-year-old patient with both chronic kidney disease and diabetes mellitus, the target blood pressure should be <130/80 mmHg, which corresponds to answer C.
Guideline-Based Recommendation
The European Society of Cardiology specifically recommends a blood pressure target of systolic <130 mmHg and diastolic <80 mmHg for patients with diabetes and chronic kidney disease, with the goal of reducing both microvascular and macrovascular complications 1
The American College of Cardiology/American Heart Association guidelines similarly recommend <130/80 mmHg for patients with CKD and hypertension, including those with diabetes 2, 3
The 2019 ESC/EASD guidelines provide stronger recommendations for more intensive control to <130/80 mmHg specifically in high-risk patients like those with both diabetes and chronic kidney disease 1
Why This Target Matters in Your Patient
Patients with both diabetes and CKD represent a particularly high-risk population where tighter blood pressure control reduces stroke, coronary events, and progression of kidney disease 1, 4
This target is lower than the standard <140/90 mmHg goal used for general hypertension because the combination of diabetes and CKD substantially increases cardiovascular and renal risk 4, 5
Critical Safety Boundaries
Do not lower systolic blood pressure below 120 mmHg, as this may increase the risk of hypoperfusion in patients with chronic kidney disease 1
Do not lower diastolic blood pressure below 70 mmHg, as this may increase cardiovascular risk in CKD patients 1, 3
Avoid systolic blood pressure dropping below 110 mmHg during treatment 2
First-Line Treatment Approach
Start with a RAAS blocker (ACE inhibitor or ARB) as first-line therapy, particularly important in patients with diabetes and CKD, especially if proteinuria or microalbuminuria is present 1, 4
Combination therapy with a RAAS blocker plus either a calcium channel blocker or thiazide/thiazide-like diuretic is typically required to achieve target blood pressure in patients with chronic kidney disease 1, 4
