  1. 21. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Författare :Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Sammanfattning : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. LÄS MER

  3. 22. Vascular and endothelial function in human hypertension, and the importance of the renin-angiotensin-aldosterone system

    Författare :Andreas Jekell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Hypertension induces structural vascular and cardiac changes with increased arterial stiffness and left ventricular (LV) hypertrophy and is major risk factor for cardiovascular morbidity and mortality. The renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system are important for blood pressure regulation and vascular function. LÄS MER

  4. 23. Echocardiographic assessment of atrioventricular plane displacement, Clinical application in patients with coronary artery disease, atrial fibrillation and aortic stenosis

    Författare :Erik Rydberg; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prognosis; aortic stenosis; atrial fibrillation; AVPD; coronary artery disease;

    Sammanfattning : Left atrioventricular plane displacement (AVPD) has been shown to correlate well with left ventricular (LV) systolic function measured as ejection fraction (EF). AVPD has also been shown to be related to diastolic performance. LÄS MER

  5. 24. T-vector and T-loop morphology analysis of ventricular repolarization in ischemic heart disease

    Författare :Aigars Rubulis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Sudden cardiac death (SCD) is responsible for about half of all cardiovascular deaths in the western world. Heterogeneous ventricular repolarization (VR) is a common denominator in the genesis of malignant ventricular arrhythmias responsible for SCD and the presence of coronary artery disease (CAD) is an aggravating factor.

  7. 25. Cardiac lipids and their role in the diseased heart

    Författare :Ismena Mardani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; Lipid droplets; Perilipins; Lipid accumulation; Metabolism; GlcCer;

    Sammanfattning : Lipids play an essential role within the heart as they are involved in energy storage, membrane stability and signaling. Changes in cardiac lipid composition and utilization may thus have profound effects on cardiac function. Importantly, the diseased heart is associated with intracellular metabolic abnormalities, including accumulation of lipids. LÄS MER
