1. 6. The important role of left atrial function parameters in clinical practice

   Författare :Ibadete Bytyci; Michael Y. Henein; Roxy Senior; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrial function; Left atrial compliance; left atrial stiffness; Clinical practice; kardiologi; Cardiology;

   Sammanfattning : The aim of this thesis is to evaluate the role of left atrial function in clinical practice based on the following studies:1)    Determining left atrial (LA) structure and myocardial function measurements that predict pulmonary capillary wedge pressure (PCWP).2)    Identifying predictors of exercise capacity in patients with HFpEF and right ventricle (RV) dysfunction.

3. 7. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

   Sammanfattning : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

4. 8. Prognostic and diagnostic value of tissue Doppler in patients with systolic heart failure

   Författare :Jens Olson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Heart failure;

   Sammanfattning : Heart failure (HF) is a condition where the heart fails to meet the need of delivery of oxygen and energy to the tissues. In spite of advances in the recent decades, the prognosis is still serious with a mortality risk comparable to severe cancer. The most common heart imaging method today is ultrasound of the heart, or echocardiography. LÄS MER

5. 9. Revalorization of poorly reactive sources by mechanochemical activation : An alternative approach for sustainable cementitious binders

   Författare :Ilda Tole; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Francesco Delogu; Pietro Lura; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay; sustainability; mechanical activation; ball milling; supplementary cementitious materials; alkali-activated materials; Byggmaterial; Building Materials;

   Sammanfattning : The latest report from the Intergovernmental Panel on Climate Change made once again clear the urge to take immediate actions to reduce the emissions of carbon dioxide and other greenhouse gases. Among the UN Sustainable Development Goals (SDGs), Nr. LÄS MER

7. 10. Echocardiography in myocardial infarction : aspects on diastolic function and evaluation by cardiovascular magnetic resonance imaging

   Författare :Martin G Sundqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Echocardiography is routinely used to evaluate patients with known or suspected myocardial infarction (MI). Cardiovascular magnetic resonance imaging (CMR) provides the ability to quantify myocardial infarction size (IS), and to establish an underlying diagnosis in MI cases with nonobstructive coronary arteries (MINOCA).
