Objective: To evaluate the efficiency of renal artery Doppler in diagnosis of secondary hypertension among cardiac patients.
Study Design: Analytical Cross-sectional study.
Place and Duration of Study: The present study was performed at Tertiary Care Center, Rawalpindi from Jan 2019 to July
2019.
Methodology: The study comprised of 50 patients with age range of 12-75 years with 90% confidence interval and 10% margin of error with prevalence of hypertension in Pakistan as 26.34%12. The study population included hypertensive patients referred for Doppler assessment of renal artery stenosis (RAS), in order to assess secondary cause of hypertension. The patients underwent angiography of kidneys within 14 days following Doppler assessment of RAS. The positive and negative outcome was presented as frequencies and percentages. The mean age was depicted as means ± standard deviation. The diagnostic features of specificity, sensitivity, negative predictive value and positive predictive values were calculated through a 2x2 table with angiographic findings considered as gold standard.
Results: In only 4(8%) patients bilaterally raised resistive index (RI) were evident. The diagnostic attributes of Doppler showed sensitivity of 48%, positive predictive value of 100% and diagnostic accuracy of 48%.
Conclusion: The role of renal artery Doppler in evaluating secondary hypertension has been over estimated. Thus, its
application needs to be restricted for elderly patients to minimize time and cost expenses.
