Key result
Captopril renography outperforms captopril challenge tests for screening renovascular hypertension, demonstrating 100% sensitivity.
Why the study?
Is captopril renography more accurate and cost-effective than the captopril challenge test for screening renovascular hypertension in hypertensive patients?
Cross-Sectional (n=519)
No
Is captopril renography more accurate and cost-effective than the captopril challenge test for screening renovascular hypertension in hypertensive patients?
Absolute Event Rate: 100% vs 67%
Captopril renography is superior to the captopril challenge test for screening renovascular hypertension and is cost-effective when targeted at patients with no obvious renal parenchymal disease and resistant or early-onset hypertension.
No takes yet. Share an insight, caveat, or question.
May support captopril renography for targeted screening; leaves open randomized confirmation of accuracy and cost-effectiveness.
Tikkanen et al. (1998) conducted a cross-sectional in Hypertension (n=519). Captopril renography (CRG) vs. Captopril challenge test (CCT) was evaluated on Sensitivity for renovascular hypertension in patients undergoing angiography. Captopril renography was superior to captopril challenge tests for screening renovascular hypertension, demonstrating 100% sensitivity and 68% specificity in patients who underwent angiography.
