Implementation of a Myocardial Perfusion Imaging Risk Algorithm to Inform Appropriate Downstream Invasive Testing and Treatment.
Kumar A, Patel DR, Harb SC, Greenberg NL, Bhargava A, Menon V, Ellis SG, Kapadia SR, Hachamovitch R, Jaber WA, Cremer PC. Kumar A, et al. Among authors: greenberg nl. Circ Cardiovasc Imaging. 2021 Apr;14(4):e011984. doi: 10.1161/CIRCIMAGING.120.011984. Epub 2021 Mar 26. Circ Cardiovasc Imaging. 2021. PMID: 33765835
With this stratification, we assessed referral for angiography and revascularization within 3 months of SPECT-MPI and intermediate-term mortality. RESULTS: Among 12 799 patients, the mean age was 66 years, and a majority were men (56.8%). ...

Mitral inertance in humans: critical factor in Doppler estimation of transvalvular pressure gradients.
Nakatani S, Firstenberg MS, Greenberg NL, Vandervoort PM, Smedira NG, McCarthy PM, Thomas JD. Nakatani S, et al. Among authors: greenberg nl. Am J Physiol Heart Circ Physiol. 2001 Mar;280(3):H1340-5. doi: 10.1152/ajpheart.2001.280.3.H1340. Am J Physiol Heart Circ Physiol. 2001. PMID: 11179082 Free article.
Although M is indispensable in assessing transvalvular pressure differences from transmitral flow, this term is poorly understood. We measured intraoperative high-fidelity left atrial and ventricular pressures and simultaneous transmitral flow velocities by using transesop …

Noninvasive estimation of transmitral pressure drop across the normal mitral valve in humans: importance of convective and inertial forces during left ventricular filling.
Firstenberg MS, Vandervoort PM, Greenberg NL, Smedira NG, McCarthy PM, Garcia MJ, Thomas JD. Firstenberg MS, et al. Among authors: greenberg nl. J Am Coll Cardiol. 2000 Nov 15;36(6):1942-9. doi: 10.1016/s0735-1097(00)00963-3. J Am Coll Cardiol. 2000. PMID: 11092668 Free article.
RESULTS: From 56 beats in 16 hemodynamic stages, inclusion of the inertial term ([deltapI]max = 1.78+/-1.30 mm Hg) in the noninvasive pressure difference calculation significantly increased the temporal correlation with catheter-based measurement (r = 0.35+/-0.24 vs. 0.81+ …

Doppler echo evaluation of pulmonary venous-left atrial pressure gradients: human and numerical model studies.
Firstenberg MS, Greenberg NL, Smedira NG, Prior DL, Scalia GM, Thomas JD, Garcia MJ. Firstenberg MS, et al. Among authors: greenberg nl. Am J Physiol Heart Circ Physiol. 2000 Aug;279(2):H594-600. doi: 10.1152/ajpheart.2000.279.2.H594. Am J Physiol Heart Circ Physiol. 2000. PMID: 10924058 Free article.
Numerical modeling resulted in similar slopes for the S (y = 0.200x - 0.127, r = 0.97), D (y = 0.247x - 0. 354, r = 0.99), and AR (y = 0.087x - 0.083, r = 0.96) waves. Consistent with numerical modeling, the convective term strongly correlates with but significantly undere …

Beneficial effects of metoprolol in heart failure associated with coronary artery disease: a randomized trial.
Fisher ML, Gottlieb SS, Plotnick GD, Greenberg NL, Patten RD, Bennett SK, Hamilton BP. Fisher ML, et al. Among authors: greenberg nl. J Am Coll Cardiol. 1994 Mar 15;23(4):943-50. doi: 10.1016/0735-1097(94)90641-6. J Am Coll Cardiol. 1994. PMID: 8106700 Free article. Clinical Trial.
OBJECTIVES: This clinical trial was performed to determine the safety and clinical impact of titrated metoprolol therapy in patients with heart failure, documented coronary artery disease and a low ejection fraction. BACKGROUND: Despite known cardiodepressant effects, long-ter …

Computer analyses of EEG-sleep in the neonate: methodological considerations.
Scher MS, Sun M, Hatzilabrou GM, Greenberg NL, Cebulka G, Krieger D, Guthrie RD, Sclabassi RJ. Scher MS, et al. Among authors: greenberg nl. J Clin Neurophysiol. 1990 Jul;7(3):417-41. doi: 10.1097/00004691-199007000-00007. J Clin Neurophysiol. 1990. PMID: 2211996 Review.
Automated techniques for EEG-sleep analysis have only recently been applied to a neonatal population. Such studies have been limited to full-term rather than preterm infants and rely on conventional methods that assume stationarity of neurophysiologic signals. ...Computati …
