1. 21. Effects of ageing and training on the human heart

   Författare :Frederic Bouvier; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ageing; endurance training; exercise capacity; myocardial perfusion scintigraphy; ejection fraction; left ventricular end-diastolic volume; ventricular arrhythmias and heart rate variability;

   Sammanfattning : The aim of the present studies was to evaluate the effects of ageing and endurance training on the human heart. One hundred and twelve healthy subjects, athletes and non-athletes, between 20 and 80 years of age and two master athletes between 70 and 80 years of age with previous myocardial infarction were investigated.

   Sammanfattning : Background: Preeclampsia (PE) is a multisystem disorder peculiar to human pregnancy and characterized by the onset of hypertension and proteinuria after the 20th week of gestation. The pathophysiology of this disorder is still not clear. LÄS MER

4. 23. Pulmonary hypertension and heart failure : physiological markers assessed by cardiovascular magnetic resonance

   Författare :João Ramos; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Pulmonary hypertension (PH) is clinically and physiologically associated with heart failure, both with reduced and preserved ejection fraction (HFrEF and HFpEF). In HFpEF, the most likely underlying pathophysiological mechanism is an impairment of left ventricular relaxation named diastolic dysfunction. LÄS MER

5. 24. The relation of blood pressure to dementia in the elderly : a community-based longitudinal study

   Författare :Chengxuan Qiu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Blood pressure; heart failure; dementia; Alzheimer s disease; apolipoprotein E gene; antihypertensive medication; aging; geriatrics; epidemiology; population-based study;

   Sammanfattning : This doctoral thesis concerns a community-based, prospective study aimed at investigating the complex relationship between blood pressure (BP) and risk of dementia in a dementia-free cohort (n = 1301) aged >=75 years in Stockholm, Sweden. After baseline survey (1987-1989), the cohort was followed for over 6 years, during which 2 waves of clinical examinations (1991-1993 & 1994-1996) for dementia and Alzheimer's disease (AD) (DSM-III-R diagnostic criteria) were performed.
