Shape index and eccentricity index are measures of left ventricular morphology. Although
both measures can be quantified with any stress imaging modality, they are not routinely …

Background Left ventricular (LV) remodeling is associated with adverse cardiovascular
events. We evaluated the added prognostic value of LV shape index (SI) assessed by gated …

Background Ventricular remodeling is predictive of congestive heart failure (CHF). We
aimed to automatically quantify a new myocardial shape variable on gated myocardial …

Background Abnormal left ventricular (LV) eccentricity index (EI) is a marker of adverse
cardiac remodeling. However, the interaction between stress-induced alterations of EI and …

Background Single-photon emission computed-tomography (SPECT) allows the
quantification of LV eccentricity index (EI), a measure of cardiac remodeling. We sought to …

Background Nomograms can be useful tools for estimating coronary artery disease (CAD)
risk. We sought to devise risk-based nomograms for stress myocardial perfusion SPECT to …

Background The purpose of this study was to evaluate the predictive value of left ventricular
(LV) shape parameters measured by gated SPECT myocardial perfusion imaging (MPI) in …

Background: Effective clinical decision making aimed at risk reduction requires use of
accurate noninvasive tests that are able to stratify patients (pts) as to their rate of important …

Background There is inconsistency in reported patient characteristics associated with
differences in basal and poststress left ventricular function (delta ejection fraction [△ EF]) …

The combination of myocardial perfusion and poststress ejection fraction (EF) provides
incremental prognostic information. This study assessed predictors of nonfatal myocardial …
