Journal ArticleDOI
Impact of Appropriate Use on the Prognostic Value of Single-Photon Emission Computed Tomography Myocardial Perfusion Imaging
Rami Doukky,Kathleen Hayes,Nathan Frogge,Gautam Balakrishnan,Venkata Satish Dontaraju,Maria Octavia Rangel,Yasmeen Golzar,Enrique Garcia-Sayan,Robert C. Hendel +8 more
TL;DR: An abnormal MPI failed to predict major adverse cardiac events, although it was associated with a high revascularization rate, and appropriate MPI use provided incremental prognostic value beyond myocardial perfusion and ejection fraction data.
Journal ArticleDOI
The safety and tolerability of regadenoson in patients with end-stage renal disease: The first prospective evaluation
Rami Doukky,Maria Octavia Rangel,Marwan Wassouf,Rizcallah Dick,Ammar Alqaid,Raysa Morales Demori +5 more
TL;DR: This is the first prospective study to confirm the safety and tolerability of regadenoson (REG)-stress in patients with ESRD.
Journal ArticleDOI
Usefulness of the Electrocardiographic P-Wave Axis as a Predictor of Atrial Fibrillation.
TL;DR: In this article, the association between abnormal electrocardiographic P-wave axis with atrial fibrillation (AF) has not been systematically studied in community-based populations, and the association was found in 4,274 participants from the Cardiovascular Health Study.
Journal ArticleDOI
Attenuation of the side effect profile of regadenoson: a randomized double-blind placebo-controlled study with aminophylline in patients undergoing myocardial perfusion imaging and have severe chronic kidney disease--the ASSUAGE-CKD trial.
Rami Doukky,Rami Doukky,Maria Octavia Rangel,Rizcallah Dick,Marwan Wassouf,Ammar Alqaid,Bosko Margeta +6 more
TL;DR: The routine standardized administration of intravenous aminophylline in patients with severe CKD substantially reduces the frequency and severity of the adverse-effects associated with regadenoson-stress without changing the ischemic burden.
Journal ArticleDOI
The prognostic value of cardiac SPECT performed at the primary care physician’s office
Rami Doukky,Rami Doukky,Nathan Frogge,Gautam Balakrishnan,Kathleen Hayes,Fareed M. Collado,Maria Octavia Rangel,Richard G. Trohman,Robert C. Hendel +8 more
TL;DR: Contemporary SPECT-MPI performed in the setting of a PCP's office carries a robust prognostic value, similar to that reported in tertiary or large-volume practice settings.
