Abstract [en]

Regular, vigorous physical activity can have a significant impact on cardiac function, leading to cardiac morphological alterations that may be challenging to distinguish from pathological changes. Therefore, new screening methods are needed to accurately differentiate between adaptive changes and pathological alterations in athletes. Vortex formation time (VFT) is an emerging method that shows potential in this regard, as it involves the formation of a rotating vortex ring in the left ventricle during the early filling phase of diastole. In this study, we investigated the difference in VFT between two groups of women: professional handball players and healthy middle-aged female athletes, along with their corresponding control groups. By using echocardiography-Doppler analysis of the heart, VFT was calculated based on the left ventricular ejection fraction, the ratio between the end-diastolic volume and the diameter of the mitral annulus, and the ratio of the atrial contraction volume to the total inflow via the mitral valve. The study reveals a significant increase in VFT in both professional handball players and middle-aged female athletes compared to their respective control groups. Moreover, statistically significant differences between handball players and middle-aged female athletes were observed, indicating that the level of physical activity may affect the VFT. These results suggest that VFT could be a promising screening tool for identifying cardiac adaptations due to long-term vigorous training, potentially enabling more accurate diagnoses of cardiac morphological alterations in athletes.

Abstract [en]

Non-invasive healthcare technologies are increasingly pivotal in research anddevelopment due to their affordability and the convenience they offer to bothhealthcare recipients and providers. Alongside traditional non-invasive methodssuch as ultrasound imaging, a variety of innovative non-invasive devices havebeen developed. These include cardiovascular diagnostic systems, bioimpedancebasedscales, and various types of analyzers. These analyzers, which can be fluidlessor fluid-based, are capable of measuring not just physical parameters of thebody but also key biomarkers like glucose and lactate. This comprehensive andtransdisciplinary thesis encompasses three distinct yet interconnected segments:1) Advanced ultrasound imaging (Papers I and II): The first explored vortexformation time in female athletes and the second detailed investigations of thesuperficial venous systems of apparently healthy volunteers.2) Validation and application of commercially available fluid-less bloodanalyzers (Papers IV-VI). These papers focus on non-invasive blood glucosemonitoring (Paper IV) and the general use of non-invasive healthcaretechnologies among female participants from socioeconomicallydisadvantaged areas (Papers V and VI).3) Design and testing of novel, fluid-based sensors, and biosensors (Papers II andIII): Paper II delves into biosensing of viruses, and paper III deals withcontinuous ex vivo glucose sensing in human blood using an enzymatic sensorin a vein replica.Each of these segments contribute to the broader understanding and advancementof non-invasive healthcare technologies, highlighting the significant role suchtechnologies play in modern healthcare research. The thesis's transdisciplinaryapproach, spanning from advanced imaging techniques to the development ofnovel biosensors, exemplifies the dynamic and evolving nature of medicaltechnology research.
