Abstract


Background: The most frequent cause of renal artery stenosis (RAS) in adults is atherosclerosis. Renal function loss and elevated blood pressure (hypertension) are potential causes of renal artery stenosis (RAS) development. Due to poor systemic blood flow to the kidneys, renal artery stenosis (RAS) may also be linked to low blood pressure. Additionally, the kidneys secrete hormones that control blood pressure. Renal artery stenosis (RAS) carries a substantial mortality risk in people with Coronary artery disease (CAD) and is linked to early cardiovascular (CV) events.

Objective: To find the Doppler association of renal artery stenosis with coronary artery disease in hypertensive versus normotensive patients.

Material and Methods: This was a case control study, conducted at Radiology/Cardiology departments of Mardan Medical Complex (MMC), Mardan for duration of 9 months. Normotensive patients and hypertensive patients both with Coronary artery disease (CAD) were included in this study. All patients with known kidney disease were excluded from the study.

Results: A total 90 patients were included in study with equal distribution in both groups (hypertensive N=45, normotensive N=45). The patients included in normotensive group had mean age of 46.1±15.8 while hypertensive patients group had mean age of 45.04±9.7.

Conclusion: The study concluded that progression of Renal Artery Stenosis (RAS) had a strong association with development of Coronary artery disease (CAD).
