    Abstract : Acute myocardial infarction (AMI), caused by ischaemic heart disease (IHD), is a leading cause of death in both men and women in the western society. Hypertension, diabetes, and smoking are examples of well-known risk factors of IHD, but also there are psychosocial factors, such as stress, vital exhaustion (unusual fatigue, irritability, and demoralization) and depression that have been associated with an increased risk in both genders.

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; video gaming; media violence; autonomic nervous system; heart rate variability; HPA axis; cortisol; sleep quality; emotional reactions; desensitization; teenagers; Psychology; psykologi;

    Abstract : Playing violent video games may provoke aggression. Psycho-physiological methods may provide knowledge about the underlying psychological processes. Most previous studies have been performed in laboratory settings at daytime with adults. READ MORE

  5. 8. Primary Hyperparathyroidism : A Study of Cardiovascular Dysfunction and its Reversibility After Parathyroidectomy

    Author : Inga-Lena Nilsson; Lars-Ove Farnebo; Uppsala universitet; []

    Abstract : Cardiovascular risk in primary hyperparathyroidism (HPT) is controversial, and studies mainly from Europe associate HPT with increased cardiovascular morbidity and mortality. Cardiovascular morphology and function were evaluated prospectively in 31 consecutive HPT patients (mean serum calcium 2.97±0. READ MORE

  6. 9. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle

    Author : Erik Olsson; Lennart Melin; Ulf Lundberg; Uppsala universitet; []
    Keywords : heart rate variability; autonomic nervous system; vagal tone; allostatic load; stress; fatigue; anxiety; depression; continuous performance; attention; cardiovascular risk; lifestyle; physical activity;

    Abstract : Heart rate varies constantly as a consequence of activity in the sympathetic and parasympathetic autonomic nervous systems (SNS and PNS). In short-term recordings, heart rate variability (HRV) is mostly related to the inhibitory activity of the vagal nerves, which are part of the PNS. READ MORE

  7. 10. Heart rate variability in patients with stable angina pectoris

    Author : Inge Björkander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ambulatory electrocardiographic registrations; autonomic nervous system; coronary artery disease; differential index; heart rate variability; prognosis;

    Abstract : The rate and modulation of the heart beat (i.e. heart rate variability; HRV) are controlled by the autonomic nervous system. Cardiac sympathetic activation decreases and parasympathetic increases HRV. READ MORE
