  1. 6. Cardiovascular dysfunction in obstructive sleep apnea

    Författare :Holger Kraiczi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; blood pressure; cardiac size; left ventricular function; endothelium-dependent vasodilation; forearm vascular conductance; natriuretic peptides;

    Sammanfattning : This thesis addresses relationships between the presence or severity of obstructive sleep apnea (OSA) and blood pressure (BP) as well as other signs of cardiovascular dysfunction.In a cross-sectional investigation of a sleep laboratory cohort of 81 patients, a dose response relationship was observed between the number of apneas plus hypopneas per hour of sleep (apnea-hypopnea index, AHI; measured with polysomnography) and office systolic and diastolic BP (SBP and DBP), daytime ambulatory DBP as well as nighttime ambulatory SBP and DBP (all ambulatory measurements taken at 20-minute intervals).

  3. 7. Influence of bone-associated and cardiovascular biomarkers on vascular events and mortality in relation to renal dysfunction

    Författare :Ping-Hsun Wu; Östen Ljunggren; Bengt Fellström; Torbjörn Linde; Jonas Spaak; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; bone markers; cardiovascular markers; proteomics; vascular event; mortality; renal function; hemodialysis; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Biomarkers can help physicians identify subjects with an increased cardiovascular risk. Apart from the clinical factors, some biomarkers have been recognized as important predictors and risk factors for cardiovascular disease in renal disease. LÄS MER

  4. 8. Vascular remodeling in pulmonary hypertension

    Författare :Ya-Ting Chang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pulmonary hypertension (PH) is a progressive obliterative vasculopathy with multifactorial etiology and high mortality rate. Endothelial dysfunction, excessive vascular remodeling, inflammation and in situ thrombosis contribute to increased vascular resistance and gradual occlusion of pulmonary vessels. LÄS MER

  5. 9. Primary Hyperparathyroidism : A Study of Cardiovascular Dysfunction and its Reversibility After Parathyroidectomy

    Författare :Inga-Lena Nilsson; Lars-Ove Farnebo; Uppsala universitet; []
    Nyckelord :Medical sciences; primary hyperparathyroidism; vascular endothelium; heart; heart rate variability; blood pressure; parathyroidectomy; calcium; parathyroid hormone; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Surgery; kirurgi;

    Sammanfattning : Cardiovascular risk in primary hyperparathyroidism (HPT) is controversial, and studies mainly from Europe associate HPT with increased cardiovascular morbidity and mortality. Cardiovascular morphology and function were evaluated prospectively in 31 consecutive HPT patients (mean serum calcium 2.97±0. LÄS MER

  7. 10. Cold finger

    Författare :Clas Backman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; vascular; microsurgery; replantation; Cold intolerance; Vasospa;

    Sammanfattning : Post Traumatic Cold Intolerance is the most common, and often the most prominent disabilityfrom hand trauma. The discomfort caused by cold is believed to be linked to a dysfunction o f thedigital vasoregulation, but its pathophysiology is poorly understood. Cold induced vasospasm, i.e. LÄS MER
