Trial Outcomes & Findings for A Study of Regadenoson in Subjects Undergoing Stress Myocardial Perfusion Imaging (MPI) Using Multidetector Computed Tomography (MDCT) Compared to Single Photon Emission Computed Tomography (SPECT) (NCT NCT01334918)

NCT ID: NCT01334918

Last Updated: 2024-12-04

Results Overview

The number of reversible defects categorized into absence or presence of ischemia (0-1 versus ≥2), as assessed by the central imaging laboratory for both SPECT and MDCT. The 17-segment model for standardized myocardial segmentation was used for myocardial perfusion readings for SPECT and MDCT. At rest and stress, each segment was scored on a 0 to 4 scale according to the amount of contrast or radiotracer the myocardium in the segment absorbed: -0: normal perfusion -1: slightly reduced contrast/radiotracer uptake -2: moderately reduced contrast/radiotracer uptake -3: severely reduced contrast/radiotracer uptake -4: absent contrast/radiotracer uptake. The median score from the 3 blinded readers for each segment was used. If the stress score was ≥ 2 and the rest score was less than the stress score, the segment was counted as having a reversible defect. A participant was classified as ischemic in the presence of 2 or more segments with reversible defects, excluding segment 17.

PRIMARY outcome

Timeframe: Day 1 and Day 2

Population: The number of participants analyzed represents the full analysis set, defined as all randomized patients with interpretable SPECT and CTP scans as determined by at least two of the three blinded readers.

The number of reversible defects categorized into absence or presence of ischemia (0-1 versus ≥2), as assessed by the central imaging laboratory for both SPECT and MDCT. The 17-segment model for standardized myocardial segmentation was used for myocardial perfusion readings for SPECT and MDCT. At rest and stress, each segment was scored on a 0 to 4 scale according to the amount of contrast or radiotracer the myocardium in the segment absorbed: -0: normal perfusion -1: slightly reduced contrast/radiotracer uptake -2: moderately reduced contrast/radiotracer uptake -3: severely reduced contrast/radiotracer uptake -4: absent contrast/radiotracer uptake. The median score from the 3 blinded readers for each segment was used. If the stress score was ≥ 2 and the rest score was less than the stress score, the segment was counted as having a reversible defect. A participant was classified as ischemic in the presence of 2 or more segments with reversible defects, excluding segment 17.
