What is Left ventricular shape index assessed by gated stress myocardial perfusion SPECT: Initial description of a new variable about?
## Background: Ventricular remodeling is predictive of congestive heart failure (chf). we aimed to automatically quantify a new myocardial shape variable on gated myocardial perfusion single photon emission computed tomography (spect) (mps) and to evaluate the association of this new spect parameter with the risk of hospitalization for chf. ## Methods and results: A computer algorithm was used to measure the 3-dimensional (3d) left ventricular (lv) shape index (lvsi), derived as the ratio of maximum 3d short- and long-axis lv dimensions, for end systole and end diastole. lvsi normal limits were obtained from stress technetium 99m sestamibi mps images of 186 patients (60% of whom were men) (control subjects) with a low likelihood of cad (< 5%). these limits were tested in a consecutive series of 93 inpatients (85% of whom were men) having mps less than 1 week after hospitalization, of whom 25 were hospitalized for chf exacerbation. variables associated with chf hospitalization were tested by receiver operating characteristic curve and multivariate logistic regression analyses. lvsi repeatability was assessed in 52 patients with ischemic cardiomyopathy who had sequential stress mps w
