Echocardiography and Noninvasive Imaging in Cardiac Resynchronization Therapy: Results of the PROSPECT (Predictors of Response to Cardiac Resynchronization Therapy) Study in Perspective
Jeroen J. Bax,John Gorcsan +1 more
TL;DR: Over the past decade, cardiac resynchronization therapy (CRT) has changed the treatment of patients with end-stage, drug-refractory heart failure by demonstrating the benefit of CRT on heart failure.

TL;DR: Patients with a concordant LV lead position showed significant improvement in LV volumes and LV systolic function, whereas patients with a discordant LVLead position showed no significant improvements.

A prospective pilot study to evaluate the relationship between acute change in left ventricular synchrony after cardiac resynchronization therapy and patient outcome using a single-injection gated SPECT protocol.
Mati Friehling,Ji Chen,Samir Saba,Raveen Bazaz,David Schwartzman,Evan Adelstein,Ernest V. Garcia,William P. Follansbee,Prem Soman +8 more
TL;DR: Patients who had an acute deterioration in synchrony after CRT had a higher composite event rate of death, heart failure hospitalizations, appropriate defibrillator discharges, and CRT device deactivation for worsening heart failure symptoms, compared with patients who had a improvement or no change.

Normal values and standardization of parameters in nuclear cardiology: Japanese Society of Nuclear Medicine working group database
TL;DR: In phase analysis of gated myocardial perfusion SPECT, a new approach for analyzing dyssynchrony, normal ranges of parameters for phase bandwidth, standard deviation and entropy were determined in four software programs.

Effects of enalapril on mortality in severe congestive heart failure: Results of the Cooperative North Scandinavian Enalapril Survival Study (CONSENSUS)
Karl Swedberg,John Kjekshus +1 more
TL;DR: The addition of enalapril to conventional therapy in patients with severe congestive heart failure can reduce mortality and improve symptoms, and the effect seems to be due to a reduction in death from progression of heart failure.
