Journal ArticleDOI
Higher Natriuretic Peptide Levels Associate With a Favorable Adipose Tissue Distribution Profile
Ian J. Neeland,Benjamin R. Winders,Benjamin R. Winders,Colby R. Ayers,Sandeep R. Das,Alice Y. Chang,Jarett D. Berry,Amit Khera,Darren K. McGuire,Gloria Lena Vega,James A. de Lemos,Aslan T. Turer +11 more
TL;DR: Higher natriuretic peptide levels were independently associated with a favorable adiposity profile, characterized by decreased visceral and liver fat and increased lower body fat, suggesting a link between the heart and adipose tissue distribution mediated through natriUREtic peptides.
Journal ArticleDOI
Inaccuracy of Estimated Resting Oxygen Uptake in the Clinical Setting
Nikhil Narang,Jennifer T. Thibodeau,Benjamin D. Levine,Benjamin D. Levine,M. Odette Gore,Colby R. Ayers,Richard A. Lange,Joaquin E. Cigarroa,Aslan T. Turer,James A. de Lemos,Darren K. McGuire +10 more
TL;DR: Estimates of resting O2 derived from conventional formulae are inaccurate, especially in severely obese individuals, and when accurate hemodynamic assessment is important for clinical decision-making, O2 should be directly measured.
Journal ArticleDOI
Relationship between perceptions about neighborhood environment and prevalent obesity: data from the dallas heart study
Tiffany M. Powell-Wiley,Colby R. Ayers,James A. de Lemos,Susan G. Lakoski,Gloria Lena Vega,Scott M. Grundy,Sandeep R. Das,Kamakki Banks-Richard,Michelle A. Albert +8 more
TL;DR: The association between perceptions of neighborhood environment and obesity among 5,907 participants in the Dallas Heart Study, a multi‐ethnic, probability‐based sample of Dallas County residents was examined.
Journal ArticleDOI
The Relationship of Right- and Left-Sided Filling Pressures in Patients With Heart Failure and a Preserved Ejection Fraction
Mark H. Drazner,Anand Prasad,Colby R. Ayers,David W. Markham,Jeffrey L. Hastings,Paul S. Bhella,Shigeki Shibata,Benjamin D. Levine +7 more
TL;DR: Right-sided filling pressures often reflect left- sided filling pressures in heart failure with preserved ejection fraction, supporting the role of estimation of jugular venous pressure to assess volume status in this condition.
Journal ArticleDOI
Effect of pulsatile and nonpulsatile flow on cerebral perfusion in patients with left ventricular assist devices
William K. Cornwell,William K. Cornwell,Takashi Tarumi,Vincent L. Aengevaeren,Vincent L. Aengevaeren,Colby R. Ayers,Punag Divanji,Qi Fu,Dean Palmer,Mark H. Drazner,Dan M. Meyer,Brian Bethea,Jeffrey L. Hastings,Naoki Fujimoto,Shigeki Shibata,Rong Zhang,Rong Zhang,David W. Markham,Benjamin D. Levine,Benjamin D. Levine +19 more
TL;DR: Cerebral blood flow in patients with CF-LVADs is comparable to that of healthy controls across a range of blood pressures, and the reduction in pulsatility afforded by CF- LVADs does not impair normal autoregulatory processes.
