OBJECTIVE The incidence of aneurysmal subarachnoid hemorrhage (aSAH) ranges from 4 to 10 per 100,000 person-years in most countries, and 30-day case fatality is high. The aim of this study was to estimate the incidence and case fatality of aSAH and to assess preictal predictors of survival in 2 large Norwegian population-based cohort studies. METHODS A(More)
BACKGROUND AND PURPOSE The joint effect of risk factors on the risk of aneurysmal SAH (aSAH) has been studied sparsely. METHODS We examined the potential synergism between cigarette smoking, hypertension, and regular alcohol consumption and the risk of aSAH in a prospective, population-based cohort of participants from the Nord-Trøndelag Health Study and(More)
OBJECTIVES Life-style factors have been associated with the risk for aneurysmal subarachnoid hemorrhage (aSAH), but it is not clear whether body mass index (BMI) and serum lipids are associated with risk. We prospectively assessed these associations in two large population studies. METHODS A total of 65,526 participants in the Nord-Trøndelag Health Study(More)
OBJECTIVE The purpose of this study was to investigate sex differences in the major established risk factors for aneurysmal subarachnoid hemorrhage (aSAH) in a large, population-based cohort. METHODS Sex differences in the established risk factors for aSAH (smoking, hypertension, and alcohol consumption) were examined in a prospective, population-based(More)
IMPORTANCE Identification of structural heart disease in asymptomatic individuals could allow early disease-modifying treatment. OBJECTIVE To examine whether echocardiographic screening in the general population improves long-term survival or reduces the risk of cardiovascular disease. DESIGN, SETTING, AND PARTICIPANTS We studied 6861 middle-aged(More)
OBJECTIVE To investigate changes and regional variations in annual incidence rates of aneurysmal subarachnoid hemorrhage (SAH) in Norway between 1999 and 2007. METHODS The authors retrospectively reviewed data from the Norwegian Patient Register for the period 1999-2007. RESULTS Crude incidence of aneurysmal SAH was 10.0/100,000 person years [95% CI(More)
PURPOSE To examine the cross-sectional relationship between drusen, late age-related macular degeneration (AMD), and cognitive function. METHODS; We included 2149 stroke-free participants from the population-based Tromsø Study in Norway. Retinal photographs were graded for presence of drusen and AMD. Cognitive function was assessed using the verbal memory(More)
OBJECT The object of this study was to examine the relationship between hospital volume and long-term mortality after treatment of intracranial aneurysms. METHODS The authors identified patients treated for intracranial aneurysms between 2002 and 2010 from patient registries of Denmark, Norway, and Sweden, and linked to data on 1-year mortality from the(More)
BACKGROUND Unrecognized myocardial infarction (MI) is a prevalent condition associated with a similar risk of death as recognized MI. It is unknown why some persons experience MI with few or no symptoms; however, one possible explanation is attenuated pain sensitivity. To our knowledge, no previous study has examined the association between pain sensitivity(More)
