  1. 11. Epidemiology of heart failure and feasibility of home care in patients with worsening chronic heart failure

    Författare :Masoud Shafazand; Göteborgs universitet; []
    Nyckelord :Chronic heart failure; mortality; deterioration; hospitalisation; gender; home care; quality-adjusted life years; emergency care; health care costs; ischaemic; non-ischaemic; health-related quality of life; conventional care; acute myocardial infarction; coronary heart disease; heart failure;

    Sammanfattning : Aim: To investigate gender-specific trends in long-term mortality in patients hospitalised for ischaemic and non-ischaemic heart failure (HF) and explore temporal trends in the risk of HF complicating acute myocardial infarction (AMI). Another aim is to characterise patients with chronic heart failure (CHF) that seek an emergency department (ED) because of their deteriorating condition and evaluate the feasibility of home care (HC) in comparison with conventional care (CC) in patients with worsening CHF.

    Sammanfattning : Introduction. Multiple clinical methods for detecting myocardial ischemia are utilised in the hospital setting each day, but there is uncertainty about their diagnostic accuracy. LÄS MER

  5. 14. Kinematics of the heart : strain and strain-rate using time-resolved three-dimensional phase contrast MRI

    Författare :Pernilla Selskog; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : During the cardiac cycle, the myocardium (heart muscle) undergoes large elastic deformations as a consequence of the active muscle contraction along the muscle :fibers and their relaxation, respectively. A four-dimensional (4D) description (three spatial dimensions + time) of the kinematics of the myocardium would bring increased understanding of the mechanical properties of the heart and may be of interest in assessing regional myocardial function.

  7. 15. Photoplethysmographic heart and respiratory rate monitoring : instrument design and evaluation

    Författare :Håkan Ugnell; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A new optical heart and respiratory rate monitor utilising the photoplethysmographic (PPG) signal is presented.The PPG method, first developed in the 1930s, is based on the fact that incident light to the skin surface is absorbed, scattered and reflected in tissue and blood.
