  3. 2. Arterial stiffness and risk factors for cardiovascular disease in young adults

    Författare :Ulrika Fernberg; Anita Hurtig-Wennlöf; Maria Fernström; Bo Fernhall; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; atherosclerosis; arterial stiffness; pulse wave analysis; intima media thickness; cardiorespiratory fitness; physical activity; body composition; young adults;

    Sammanfattning : Atherosclerosis is a complex, chronic vessel wall disease that often leads to severe and acute cardiovascular diseases (CVD), such as myocardial infarction and stroke. CVD are the most common cause of death, both globally and in Sweden. LÄS MER

  4. 3. Epidemiological, mechanistic and genetic aspects of vascular ageing and arterial stiffness in the population

    Författare :Mikael Gottsäter; Internmedicin - epidemiologi; []
    Nyckelord :Vascular ageing; Arterial stiffness;

    Sammanfattning : The core feature of vascular ageing is the age-associated stiffening of the large, elastic arteries, or arteriosclerosis. This results in a diminished volume-buffering function and is therefore central for the increase in systolic blood pressure and pulse pressure seen with advancing age. LÄS MER

  5. 4. Arterial wall stiffness in man. On gender differences and abnormalities in insulin dependent diabetes mellitus and alpha1-antitrypsin deficiency

    Författare :Åsa Rydén Ahlgren; Malmö Klinisk fysiologi och nuklearmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex characteristics.; abdominal aortic aneurysm; arterial stiffness; alpha1-antitrypsin deficiency; ultrasonography; Insulin dependent diabetes mellitus; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The mechanical properties of major arteries may reflect early manifestations of vascular disease and are also of interest because they are important for cardiac work. Using echo-tracking sonography and blood pressure measurements, arterial stiffness and diameters were investigated in healthy individuals as well as in patients with insulin dependent diabetes mellitus (IDDM) or alpha1-antitrypsin deficiency (alpha1-AT deficiency).

  7. 5. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging

    Författare :Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.
