Post-stroke losartan and captopril treatments arrest hemorrhagic expansion in SHRsp without lowering blood pressure.
Abstract We assessed the ability of poststroke losartan and captopril treatment to attenuate hematoma expansion and plasma extravasation after intracerebral hemorrhagic stroke in Kyoto-Wistar stroke-prone hypertensive rats (SHRsp). Cerebrum volume, herniation and surface areas exhibiting new and old hemorrhages and albumin extravasation were measured prior to and after stroke and following 30 and 60 days of post-stroke losartan or captopril treatment in Evans Blue dye perfused brains. Lesion morphology was studied in serial sections. Losartan or captopril treatment initiated at stroke prevented death for 60 da...

Vasomodulatory effects of the angiotensin II type 1 receptor antagonist losartan on experimentally induced cerebral vasospasm after subarachnoid haemorrhage
ConclusionIn a physiological and pathophysiological setup, losartan reduces a PGF2-induced vasoconstriction and reverses a PGF2a-precontraction completely. This fact can be integrated in pushing forward further concepts trying to antagonise/prevent cerebral vasospasm after SAH.

Cerebrovascular recovery after stroke with individual and combined losartan and captopril treatment of SHRsp.
Abstract We assessed whether the superior restoration of cerebrovascular function after hemorrhagic stroke by losartan versus captopril treatment was due to better BP, uremia, uricaemia, or aldosterone control in Kyoto Wistar stroke-prone-hypertensive rats and evaluated whether elevated angiotensin II (A2) levels enhanced the effectiveness of losartan treatment. Constriction was studied in the middle cerebral arteries (MCAs) using a pressure myograph. Post-stroke survival increased from 21 to 310 and 189days respectively with losartan and captopril treatment. Neither treatment reduced BP, both reversed uremia and ...

Pattern of antihypertensive therapy among diabetic hyperten- sive patients in zewditu memorial hospital, addis ababa.
CONCLUSION: The pattern of antihypertensive drug therapy in our patients was consistent with the current treatment guidelines. However, the majority of diabetic-hypertensive patients did not reach target blood pressure. PMID: 27476227 [PubMed - in process]

Roles of Hypertension in the Rupture of Intracranial Aneurysms Basic Sciences
Conclusions— Normalization of blood pressure after aneurysm formation prevented aneurysmal rupture in mice. In addition, we found that the inhibition of the local renin–angiotensin system independent from the reduction of blood pressure can prevent aneurysmal rupture.

Crosstalk between the angiotensin and endothelin-system in the cerebrovasculature.
Abstract Investigations have shown a multifactorial process as cause for the poor outcome after subarachnoid hemorrhage (SAH), including inflammation, early brain injury, cortical spreading depression, lack of cerebral autoregulation and the cerebral vasospasm (CVS) itself. Losartan may have a beneficial effect after SAH - preventing CVS, restoring cerebral autoregulation, reducing inflammation and early brain injury. Also some data is available for an AT1-receptor-upregulation and upregulated gene expression after subarachnoid hemorrhage, but the functional role of angiotensin on the cerebrovascular contractility...
