Trial Outcomes & Findings for Effect of Ranolazine on Myocardial Perfusion Assessed by Serial Quantitative Exercise SPECT Imaging (NCT NCT01221272)

NCT ID: NCT01221272

Last Updated: 2014-09-03

Results Overview

PDS is the amount (percent) of the myocardium with decreased blood flow. A lower percentage means more of the myocardium is receiving blood flow. Measurements were obtained by gated single photon emission computed tomography (SPECT) imaging following exercise at the end of the ranolazine and placebo treatment periods.

TPD is a score that measures the overall impact of a region of decreased myocardial blood flow, incorporating both the amount and severity of the decreased flow. TPD is measured on a scale of 0-100, with higher scores being worse and lower scores being better. Measurements were obtained by SPECT imaging following exercise at the end of the ranolazine and placebo treatment periods.

Population: Efficacy Analysis Set

Perfusion defect severity was assessed for each participant as the percentage of the 17 myocardium segments with a relative perfusion defect score of 3 or 4 on a 0-4 scale. Segment scores are: 0 = normal perfusion; 1 = mild reduction in counts-not definitely abnormal; 2 = moderate reduction in counts-definitely abnormal; 3 = severe reduction in counts; 4 = absent uptake (lower scores correspond to less severity and higher scores correspond to increased severity). A lower percentage means fewer segments have severely reduced blood flow. Measurements were obtained by SPECT imaging following exercise at baseline and at the end of Periods 1 and 2.

Exercise-induced reversible PDS was derived as the exercise PDS at baseline and at the end of Periods 1 and 2 minus the resting PDS at baseline. A lower percentage means more of the myocardium is receiving blood flow. Measurements were obtained by SPECT imaging at baseline both at rest and following exercise and following exercise at the end of Periods 1 and 2.
