Journal ArticleDOI
Estimation of Central Aortic Pressure Waveform by Mathematical Transformation of Radial Tonometry Pressure Validation of Generalized Transfer Function
Chen Huan Chen,Erez Nevo,Barry J. Fetics,Peter H. Pak,Frank C.P. Yin,W L Maughan,David A. Kass +6 more
TL;DR: Central aortic pressures can be accurately estimated from radial tonometry with the use of a generalized TF, and the reconstructed waveform can provide arterial compliance estimates but may underestimate the augmentation index because the latter requires greater fidelity reproduction of the wave contour.
Journal ArticleDOI
Improved Left Ventricular Mechanics From Acute VDD Pacing in Patients With Dilated Cardiomyopathy and Ventricular Conduction Delay
David A. Kass,Chen Huan Chen,Cecilia W. Curry,Maurice Talbot,Ronald D. Berger,Barry J. Fetics,Erez Nevo +6 more
TL;DR: VDD pacing acutely enhances contractile function in heart failure patients with intraventricular conduction delay and single-site pacing at the site of greatest delay achieves similar or greater benefits to biventricular pacing in such patients, to clarify pacing-effect mechanisms.
Journal ArticleDOI
Combined Ventricular Systolic and Arterial Stiffening in Patients With Heart Failure and Preserved Ejection Fraction. Implications for Systolic and Diastolic Reserve Limitations
TL;DR: Patients with HF-lnEF have systolic-ventricular and arterial stiffening beyond that associated with aging and/or hypertension, which may play an important pathophysiological role by exacerbating systemic load interaction with diastolic function, augmenting blood pressure lability, and elevating cardiac metabolic demand under stress.
Journal ArticleDOI
Left ventricular or biventricular pacing improves cardiac function at diminished energy cost in patients with dilated cardiomyopathy and left bundle-branch block
Gregory S. Nelson,Ronald D. Berger,Barry J. Fetics,Maurice Talbot,Julio C. Spinelli,Joshua M. Hare,David A. Kass +6 more
TL;DR: Ventricular resynchronization by left ventricular or biventricular pacing/stimulation in DCM patients with left bundle-branch block acutely enhances systolic function while modestly lowering energy cost should prove valuable for treating DCM Patients with basal dyssynchrony.
Journal ArticleDOI
Noninvasive single-beat determination of left ventricular end-systolic elastance in humans
Chen Huan Chen,Barry J. Fetics,Erez Nevo,Carlos E. Rochitte,Kuan Rau Chiou,Phillip Yu An Ding,Miho Kawaguchi,David A. Kass +7 more
TL;DR: The E(es) can be reliably estimated from simple noninvasive measurements and should broaden the clinical applicability of this useful parameter for assessing systolic function, therapeutic response and ventricular-arterial interaction.
