Løvik, Katja; Laupsa-Borge, Johnny; Logallo, Nicola; Helland, Christian Andre (Journal article; Peer reviewed, 2021)Dyslipidemia is a well-established risk factor for coronary artery disease. However, the effect on cerebral artery disease, and more specifically the rupture risk of intracranial aneurysms, is unclear and has not yet been ... -
Impaired cerebrovascular reactivity may predict delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage
Bøthun, Marianne Lundervik; Haaland, Øystein Ariansen; Moen, Gunnar; Logallo, Nicola; Svendsen, Frode; Thomassen, Lars; Helland, Christian Andre (Peer reviewed; Journal article, 2019)Introduction: Delayed cerebral ischemia (DCI) is a major cause of disability and death after aneurysmal subarachnoid hemorrhage.
