  2. 21. Angiotensin-converting enzyme in cardiovascular function and dysfunction

    Author : Liza Ljungberg; Toste Länne; Karin Persson; Urban Alehagen; Thomas Kahan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Angiotensin-converting enzyme (ACE) is a key enzyme in the renin-angiotensin system, converting angiotensin I to the vasoactive peptide angiotensin II, and degrading bradykinin. Angiotensin II is a multifunctional peptide, acting on a number of different tissues. READ MORE

  4. 22. Age and gender differences in risk factor burden, myocardial dysfunction and cardiovascular events in relation to glucose metabolism

    Author : Margrét Leosdottir; Internmedicin - epidemiologi; []
    Keywords : Age; cardiovascular disease; diabetes; echocardiography; gender; glucose; left ventricular function; Nt-proBNP; self-rated health;

    Abstract : The risk of cardiovascular disease (CVD) and heart failure (HF) among individuals with diabetes is at least two times greater than in non-diabetic subjects. However, the excess risk of CVD in diabetic subjects seems to decrease with age. READ MORE

  5. 23. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

    Author : Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

  6. 24. Ventricular fibrillation and defibrillation in patients with implantable cardioverter defibrillators

    Author : Mikael Runsiö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ventricular fibrillation; defibrilla~ion; implantable cardioverter defibrillator; haemodynamic; metabolism; hyperaemia; ischaemia; myocardial injury; histamine; neuropeptide 1: noradrenaline; endothelin; histamine; positron emission tomography.;

    Abstract : Since the introduction of the implantable cardioverter defibrillator for humans with malignant ventricular arrhythmias in 1980, over 50, 000 patients world wide have received this device. The implantation procedure is simple and resembles the implantation of an ordinary pacemaker. READ MORE

  7. 25. New insights in the assessment of right ventricular function : an echocardiographic study

    Author : Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; echocardiography; right ventricle; ischaemic heart disease; pulmonary hypertension; aortic stenosis; aortic valve replacement; three dimensional echocardiography; speckle tracking echocardiography; Cardiology; kardiologi;

    Abstract : Background:  The right ventricle (RV) is multi-compartmental in orientation with a complex structural geometry. However, assessment of this part of the heart has remained an elusive clinical challenge. READ MORE
