Publikováno v: CJC Open, Vol 3, Iss 12, Pp S44-S52 (2021)

Background: Postural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance that primarily impacts female patients of childbearing age. The role of sex differences in POTS is not well understood. We sought to identify se

Autor: Jin-Woo Park, Luis E. Okamoto, Sung-Hwan Kim, Seol-Hee Baek, Joo Hye Sung, Namjoon Jeon, Alfredo Gamboa, Cyndya A. Shibao, André Diedrich, Byung-Jo Kim, Italo Biaggioni

Publikováno v: Hypertension. 80:792-801

Background: Standard autonomic testing includes a 10-minute head-up tilt table test to detect orthostatic hypotension. Although this test can detect delayed orthostatic hypotension (dOH) between 3 and 10 minutes of standing, it cannot detect late-ons

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 10, Iss 7 (2021)

Background Supine hypertension affects a majority of patients with autonomic failure; it is associated with end‐organ damage and can worsen daytime orthostatic hypotension by inducing pressure diuresis and volume loss during the night. Because symp

Splanchnic Venous Compression Enhances the Effects of ß‐Blockade in the Treatment of Postural Tachycardia Syndrome

Autor: Emily C. Smith, André Diedrich, Satish R. Raj, Alfredo Gamboa, Cyndya A. Shibao, Bonnie K. Black, Amanda Peltier, Sachin Y. Paranjape, Italo Biaggioni, Luis E. Okamoto

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 9, Iss 14 (2020)

Background Splanchnic venous pooling induced by upright posture triggers a compensatory increase in heart rate (HR), a response that is exaggerated in patients with postural tachycardia syndrome. To assess whether abdominal compression attenuates ort

Publikováno v: Journal of Translational Autoimmunity, Vol 2, Iss , Pp - (2019)

Background: Activating autoantibodies (AAb) to adrenergic receptors (AR) have previously been reported in patients with postural tachycardia syndrome (POTS). These AAb may contribute to a final common pathway for overlapping disease processes, reflec
