1. 26. Management of chronic obstructive pulmonary disease and chronic heart disease in primary health care : Guidelines, patients and comorbidity

   Författare :Maaike Giezeman; Kersti Theander; Mikael Hasselgren; Josefin Sundh; Jörgen Thorn; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; chronic heart failure; heart disease; patient outcomes; exercise self-efficacy; comorbidity; primary health care; cohort study;

   Sammanfattning : The overall aim of this compilation thesis was to explore different aspects of the management of patients with chronic obstructive pulmonary disease (COPD) and heart disease in primary health care: guideline adherence in chronic heart failure (CHF) management (I); comparing patients with COPD and heart failure, and factors associated with the pa-tients’ exercise self-efficacy (II); and the influence of comorbid heart disease in COPD over time (III–IV).Materials and methods: Cross-sectional data from primary health care: 155 patients with heart failure (I) and 150 with COPD and/or heart failure (II).

3. 27. Mechanical and histological disturbances in advanced heart failure and cardiac transplantation

   Författare :Matteo Cameli; Michael Henein; Guy Lloyd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Advanced heart failure; heart transplantation; speckle tracking echocardiography; left ventricular function; right ventricular function; left ventricular fibrosis; left ventricular filling pressure; atrial strain; kariologi; Cariology;

   Sammanfattning : The general purpose of this thesis is to establish capability and accuracy of speckle tracking echocardiography (STE) in assessing left atrial (LA), left ventricular (LV) and right ventricular (RV) function and their correlation with myocardial fibrosis, filling pressure and clinical outcomes in advanced heart failure (HF) patients before and after heart transplantation (HT).I demonstrated that HT recipients had impaired LV twist dynamics in the form of reduced rotation twist angle and untwist rate but time to peak twist was not different from the age matched controls and other cardiac surgical patients.

4. 28. Risk assessment in patients with acute myocardial infarction treated with thrombolysis

   Författare :Bassem Abdel Samad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :echocardiography; exercise stress test; heart rate variability; Holter recording; low-dose dobutamine echocardiography; myocardial infarction; myocardial perfusion scintigraphy; myocardial viability; prognosis; thrombolysis.;

   Sammanfattning : Risk stratification in patients with acute myocardial infarction is essential for guiding the clinical decision concerning management. Thrombolytic therapy and other new management policies have led to a significant reduction in mortality from myocardial infarction. LÄS MER

5. 29. On-line vectorcardiography in ischemic heart disease

   Författare :Peter Lundin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Vectorcardiography; ischemia monitoring; coronary artery disease; exercise test; echocardiography; dobutamine; unstable angina pectoris; myocardial infarction; prognosis.;

   Sammanfattning : The clinical usefulness of continuous on-line vector cardiography (VCG) was assessed in 435 patients, admitted to the coronary care unit. The ability of 24-hour VCG monitoring to differentiate patients with or without ischemic heart disease (IHD), to provide long-term prognostic information and to predict results from a predischarge exercise test in patients with unstable angina pectoris or acute myocardial infarction (MI) was evaluated.

7. 30. Electromechanical effects and optimization modalities of cardiac resynchronization therapy

   Författare :Cinzia Valzania; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cardiac resynchronization therapy; coronary blood flow; dyssynchrony; echocardiography; exercise; heart failure; hemodynamics; intracardiac electrogram; intracardiac impedance; optimization;

   Sammanfattning : Background and aims: Heart failure is a major health care problem, with high morbidity and mortality rates. In recent years, cardiac resynchronization therapy (CRT) has become an established additive treatment for patients with advanced heart failure, left ventricular (LV) dysfunction, and wide QRS complex.
