Comparison of circadian blood pressure variations in hypertensive patients with renal artery stenosis and essential hypertension.
Ambulatory blood pressure measurements in 20 hypertensive patients with uni- or bilateral renal artery stenosis were compared with those in 20 essential hypertensive patients. Analysis of the 24 hour blood pressure curve of the renal artery stenosis group shows a tendency to equalization of blood pressure throughout the day. The nocturnal decrease of systolic or diastolic blood pressure was not significantly different between the two groups (9.2 vs. 15.3 mmHg). The blunted curve seems to be related more to the severity of hypertension than to its aetiology, but further studies are required to elucidate this point.
