Journal ArticleDOI
Effect of Aging and Physical Activity on Left Ventricular Compliance
Armin Arbab-Zadeh,Erika Dijk,Anand Prasad,Qi Fu,Pilar Torres,Rong Zhang,James D. Thomas,Dean Palmer,Benjamin D. Levine +8 more
TL;DR: A sedentary lifestyle during healthy aging is associated with decreased left ventricular compliance, leading to diminished diastolic performance, which may contribute to the high incidence of heart failure in the elderly.
Journal ArticleDOI
Cardiac Origins of the Postural Orthostatic Tachycardia Syndrome
Qi Fu,Tiffany B. VanGundy,M. Melyn Galbreath,M. Melyn Galbreath,Shigeki Shibata,Shigeki Shibata,Manish Jain,Manish Jain,Jeffrey L. Hastings,Paul S. Bhella,Paul S. Bhella,Benjamin D. Levine +11 more
TL;DR: Exercise training improved or even cured this syndrome in most patients and it seems reasonable to offer POTS a new name based on its underlying pathophysiology, the "Grinch syndrome," because in this famous children's book by Dr. Seuss, the main character had a heart that was "two sizes too small."
Journal ArticleDOI
Hemodynamics of orthostatic intolerance: implications for gender differences
TL;DR: Cardiac mechanics and Frank-Starling relationship may be important mechanisms underlying the gender difference in orthostatic tolerance, which is associated with decreased cardiac filling rather than reduced responsiveness of vascular resistance during Orthostatic challenges.
Journal ArticleDOI
Effects of gender and hypovolemia on sympathetic neural responses to orthostatic stress.
TL;DR: The results indicate that men and women have comparable sympathetic neural responses during orthostatic stress under normovolemia and hypovolemic conditions, which may overwhelm the vasomotor reserve available for vasoconstriction or precipitate neurally mediated sympathetic withdrawal and syncope.
Journal ArticleDOI
The Effects of Aging and Physical Activity on Doppler Measures of Diastolic Function
Anand Prasad,Zoran B. Popović,Armin Arbab-Zadeh,Qi Fu,Dean Palmer,Erika Dijk,Neil L. Greenberg,Mario J. Garcia,James D. Thomas,Benjamin D. Levine +9 more
TL;DR: Age-associated abnormalities in Doppler measures of myocardial filling and relaxation are only partially minimized by lifelong endurance training and therefore may be more specific to the aging process than secondary to years of deconditioning.
