Paradoxical increase in ambulatory SBP in coarctation of aorta a compared to essential hypertension.

ABSTRACT:

Background

The relationship between office vs. ambulatory blood pressure (BP) indices are well-studied in patients with essential hypertension and based on these data, it is known that the average 24-h ambulatory BP is typically lower than office BP. However, emerging data show that office SBP underestimates arterial afterload in patients with coarctation of aorta (COA), and a minimal increase in stroke volume during low-intensity exercise results in an exaggerated rise in SBP as compared to those with essential hypertension. We hypothesized that COA patients will have higher ambulatory SBP and a higher prevalence of masked hypertension compared to patients with essential hypertension.

Methods

Case-control study of 118 COA patients and 118 patients with essential hypertensio
