Falling system dysfunction

Cardiovascular Paradoxical severe hypertension occurred in three patients with advanced chronic kidney disease and bilateral renal artery stenosis. After the introduction of ramipril, an initial fall in blood pressure was followed by a paradoxical increase in blood pressure. This was postulated to be caused by activation of the renin-angiotensin-aldosterone system, as a result of renal artery stenosis and renal dysfunction [55 ].
