1. 21. The Role of Impaired Interatrial Conduction in Paroxysmal Atrial Fibrillation

   Författare :Pyotr Platonov; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electrophysiology; Cardiovascular system; anatomy; interatrial conduction; lone atrial fibrillation; Kardiovaskulära systemet;

   Sammanfattning : The aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the presence of double-peaked configurations of P-wave spatial magnitude in patients with lone paroxysmal AF compared with healthy individuals (I), suggesting the presence of interatrial conduction delays localised in the posterior-inferior interatrial route.

   Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER

4. 23. Urinary Biomarkers and Patient Outcome in Chronic Kidney Disease and Atherosclerotic Heart Disease: The value of IgM-uria and IgG-uria

   Författare :Rafid Tofik; Njurmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteinuria; Albuminuria; urine IgM; urine IgG; glomerulonephritis; chronic kidney disease; atherosclerosis; cardiovascular disease; diabetic kidney disease.;

   Sammanfattning : Risk stratification of patients with chronic kidney disease and atherosclerotic heart disease is crucial. Microalbuminuria (MA) is associated with an increased risk of kidney and cardiovascular (CV) death, especially in patients with diabetes. LÄS MER

5. 24. Permeability of the glomerular filtration barrier in relation to the size, shape, charge and deformability of the permeating molecules

   Författare :Daniel Asgeirsson; Njurmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteinuria; capillary physiology; peritoneal membrane; dialysis; microalbuminuria; cardiovascular; endothelial dysfunction; diagnosis;

   Sammanfattning : Characterization of the glomerular filtration barrier is of fundamental importance for understanding the pathophysiology of proteinuric kidney diseases. Furthermore, it can be of key value in the understanding of microalbuminuria, which is often associated with endothelial dysfunction in conjunction with cardiovascular disease. LÄS MER

7. 25. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery

   Författare :Faleh Alrashidi; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Modified Ross Operation; Aortic Root surgery; Microemboli signals MES ; Transcranial Doppler TCD ; Acute plateletphersis APP ; Transesophageal echocardiography TEE ; de-airing;

   Sammanfattning : Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation.
