  2. 21. Obstructive sleep apnea and cardiovascular morbidity

    Author : Yüksel Peker; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; cardiovascular; hypertension; coronary artery disease; hospitalization; cost utility; morbidity; mortality; secondary prevention; angiotensin II; CPAP;

    Abstract : Obstructive sleep apnea (OSA) affects 24 % of middle-aged men and 9 % of women in USA but the treatment criterion, daytime sleepiness is reported by 17 and 22 % of these subjects, respectively. Some previous studies have suggested an association between OSA and cardiovascular disease (CVD), but the conclusions have been conflicting due to co-existing traditionally recognized risk factors.

  4. 22. Three-dimensional assessment of cardiac function; When right is wrong

    Author : Ellen Ostenfeld; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Key words Three-dimensional echocardiography; cardiac magnetic resonance imaging; cardiac function; volumes; atria; ventricles; pulmonary hypertension; right heart catheterization; right ventricular pressure load.;

    Abstract : Assessment of the right side of the heart is important in patients with heart disease; especially in patient with elevated pressure in the lung circulation. Decreased right ventricular function and elevated pressure in the right atrium are of poor prognostic value. READ MORE

  5. 23. Long-term follow-up after surgery for chronic thromboembolic pulmonary hypertension

    Author : Janica Kallonen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Pulmonary endarterectomy (PEA) is the treatment recommended for all operable patients with chronic thromboembolic pulmonary hypertension (CTEPH). The aim of this thesis was to evaluate long-term survival, quality of life (QoL) and functional status in patients with CTEPH who have undergone PEA. READ MORE

  6. 24. Nitric oxide in experimental pulmonary embolism

    Author : Kristofer F Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination. READ MORE

  7. 25. Pulmonary hypertension and heart failure : physiological markers assessed by cardiovascular magnetic resonance

    Author : João Ramos; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Pulmonary hypertension (PH) is clinically and physiologically associated with heart failure, both with reduced and preserved ejection fraction (HFrEF and HFpEF). In HFpEF, the most likely underlying pathophysiological mechanism is an impairment of left ventricular relaxation named diastolic dysfunction. READ MORE
