Pages: 55 - 57
Purpose: In order to determine if the height of a subject could be a reliable surrogate variable to determine the pulse wave travelling distance within the aorta, we investigated the anatomical distance between the aortic valve nidus and the hyoid bone. Methods: Using 28 patient’s chest CT-scans. From...

Filippo Valbusa, Andrea Angheben, Verena Zerbato, Andrea Chiampan, Davide Agnoletti, Cristiano Fava, Zeno Bisoffi, Guido Arcaro
Pages: 56 - 56
Background: In Italy, the prevalence of seropositivity for Trypanosoma cruzi in immigrants from endemic countries is about 11.3% (30.7% for Bolivian immigrants). The disease acute phase is usually asymptomatic, often leading to chronic infection that may remain silent for life (chronic indeterminate...

4.7 MEASUREMENT OF ARTERIAL STIFFNESS USING A CONNECTED BATHROOM SCALE: CALIBRATION AGAINST SPHYGMOCOR

Pierre Boutouyrie, Hakim Khettab, David Campo, Roger Yu, Nadine Buard
Pages: 56 - 56
Background: Measurement of arterial stiffness (AS) is still considered difficult. We developed a non-invasive technique to assess AS from a connected bathroom scale, based on ballistocardiography (BCG) and impedance plethysmography (IPG). Methods: We included 198 subjects and patients, 111 for calibration...

4.2 SEX-DEPENDENT EFFECTS OF PERIVASCULAR ADIPOSE TISSUE ON VASCULAR FUNCTION

Christian Delles, Sarah McNeilly, Sheon Mary, Adam Sheikh, Heather Small
Pages: 56 - 56
Background: Premenopausal women are relatively protected against hypertension compared to males. Estrogen levels have been identified as a potential underlying cause, but the pathophysiological mechanisms remain incompletely understood. We hypothesised that sex-dependent effects of perivascular adipose...

4.8 INCREASED CARDIAC WORKLOAD IN THE UPRIGHT POSTURE IN MALE SUBJECTS: NON-INVASIVE HEMODYNAMICS IN MEN VERSUS WOMEN

Pauliina Kangas, Anna Tahvanainen, Antti Tikkakoski, Jenni Koskela, Marko Uitto, Jari Viik, Mika Kahonen, Tiit Koobi, Emeritus Jukka Mustonen, Ilkka Porsti
Pages: 56 - 56
Background: Men and women differ in the risk of cardiovascular disease, but the underlying mechanisms are not completely understood. We examined possible sex-related differences in supine and upright cardiovascular regulation. Methods: Hemodynamics were recorded from 167 men and 167 women of matching...

4.3 ABNORMAL PRESSURE WAVE REFLECTION ACCELERATES THE DEVELOPMENT OF HYPERTENSION VIA THE INCREASE OF ARTERIAL STIFFNESS

Hirofumi Tomiyama, Akira Yamashina, Shunsuke Komatsu, Kazuki Shiina, Chisa Matsumoto, Shogen Fujii, Taishiro Chikamori
Pages: 56 - 56
Objectives: It is noted that not only arterial stiffness but also abnormal pressure wave reflection are risks for the development of hypertension. However, the association between arterial stiffness and pressure wave reflection in the development of hypertension has not been fully clarified. The present...
