11. Regulation of vascular function by fluid mechanical forces. Development of a new vascular experimental platform for integrative physiological and molecular biological studies of living conduit vessels
Sammanfattning : The vascular endothelium is a multifunctional interface between blood flow and target organs and is continuously exposed to fluid mechanical forces such as shear stress, compressive, and tensile forces. Both in vivo and in vitro data indicate that biomechanical forces exert important modulating effects on key vascular functions. LÄS MER
12. Autonomic function and myocardial repolarisation. Studies in renal diseases and in spinal cord injury
Sammanfattning : Both experimental and clinical evidence indicates that cardiac parasympathetic markers such as baroreflex sensitivity (BRS) and heart rate variability (HRV) have significant prognostic value. Furthermore, increased myocardial repolarisation lability reflected by increased QT variability index (QTVI) has been identified as a predictor for sudden cardiac death. LÄS MER
13. Timing of valve replacement in aortic stenosis. Clinical, diagnostic and prognostic factors of importance
Sammanfattning : .... LÄS MER
14. Noninvasive characterization of patients with monomorphic ventricular tachycardia and ventricular fibrillation using the signal-averaged electrocardiogram. A study on late potentials and spectral turbulence in patients with ischemic heart disease and in healthy subjects
Sammanfattning : Many people die suddenly from sustained ventricular tachyarrhythmias caused by ischemic heart disease, and the sudden death may be the first presentation of heart disease. If the patients at risk of ventricular tachyarrhythmia could be identified, some patients may be saved. LÄS MER
15. Endogenous tissue-type plasminogen activator andendothelial function in vivo. A clinical perspective
Sammanfattning : Endogenous fibrinolysis is initiated by the glycoprotein tissue-type plasminogen activator (tPA), which is released from the vascular endothelium. Plasminogen activator inhibitor type 1 (PAI-1) is the main inhibitor of tPA. LÄS MER
