Normal systolic blood pressure range for renal disease patients?

Normal systolic blood pressure range for renal disease patients?

• A. 70-80 mmHg
• B. 80-90 mmHg
• C. 90-100 mmHg
• D. 100-110 mmHg

Answer: (B)

In renal disease, preserving renal perfusion is crucial because the kidneys are more sensitive to drops in perfusion pressure and autoregulation may be blunted. This makes a low-normal blood pressure target desirable to sustain adequate renal blood flow without pushing pressures high enough to cause edema or hypertension-related strain. Targeting systolic blood pressure in the 80–90 mmHg range helps maintain sufficient renal perfusion while avoiding both hypotension and excessive afterload. Values lower than this risk renal ischemia, whereas higher values can increase stress on the cardiovascular system and potentially worsen kidney injury in these patients. So, the best choice reflects keeping the kidneys perfused with a low-normal systolic pressure.
