Trial Outcomes & Findings for Myocardial Perfusion MRI (NCT NCT01490294)
NCT ID: NCT01490294
Last Updated: 2014-05-22
Results Overview
Rest and stress perfusion Magnetic Resonance (MR) images were evaluated by 3 independent blinded readers for presence/absence of cardiac perfusion deficits in 3 myocardial regions representing the 3 coronary territories/arteries (left anterior decendent \[LAD\], left circumflex \[LCX\], right coronary artery \[RCA\]). Data were compared to the corresponding regional data from Single Photon Emission Computer Tomography (SPECT). The number of regional assessments was calculated by multiplication of the number of participants with the number of the blinded readers and number of the myocardial regions.

Rest and stress perfusion MR images were evaluated by the respective clinical investigator for presence/absence and characterization of cardiac perfusion deficits as "scar" in the 3 myocardial regions representing the 3 coronary territories/arteries (LAD, LCX, RCA). These data were compared to the corresponding regional SPECT diagnosis of "scar". The number of regional assessments is defined as the number of segments with diagnosis "scar" assessed by the investigator.

Timeframe: Immediately within approximately 5 seconds after Gadobutrol bolus administrationPopulation: PPS
Rest and stress perfusion MR images were evaluated by the respective clinical investigator for detailed characterization of cardiac perfusion deficits i.e. scar, ischemia or a mixture of both in 16 myocardial segments (defined according to the American Heart Association).MR data were compared to the corresponding segmental data from SPECT. The number of segmental assessments was calculated by multiplication of the number of participants with the number of the myocardial segments.

Timeframe: Immediately within approximately 5 seconds after Gadobutrol bolus administrationPopulation: PPS
MPRI was calculated as decribed in outcome measure 22 on stress and rest perfusion MR images by an independent MR expert for 16 myocardial segments (defined according to the American Heart Association). MPRIs \<= 1.5 (perfusion defect) and \>1.5 (normal) were then compared to presence/absence of perfusion defects in the segmental data from SPECT. The number of segmental assessments was calculated by multiplication of the number of participants with the number of the blinded readers and the number of the myocardial segments.

Timeframe: Immediately within approximately 5 seconds after Gadobutrol bolus administrationPopulation: PPS
The signal intensity (SIrel) is determined over time. SI (SIrel) is the upslope in myocardium divided by upslope of the ventricle, as assessed for normal and underperfused segments. SI(rel) = upslope myocard / upslope ventricle. MR segments were evaluated for signal intensity (SIrel) in order to assess if a difference between normal and diseased (i.e. ischemia/scar/mixed) segments could be demonstrated ("normal/diseased" was defined by central reading of SPECT).

Delayed enhancement (DE) -\[accumulation of Gadobutrol in infarcted tissue and visualized as Gadobutrol enhanced regions\]- MR images acquired at different time points, were evaluated by the clinical investigator for presence/absence of DE at 5 - 20 minutes post injection in 3 myocardial regions representing the 3 coronary territories/arteries (LAD, LCX, RCA). DE data were compared to the diagnosis "scar" derived from SPECT. The number of regional assessments is defined as the number of regions with diagnosis "scar" assessed by the investigator.

Timeframe: Delayed enhancement was measured at 5, 10, 15, and 20 minutes after Gadobutrol bolus administrationPopulation: All participants in PPS with assessment for this outcome measure. Only participants with the finding "scar" in at least 1 segment in SPECT were included.
Delayed enhancement (DE)-\[accumulation of Gadobutrol in infarcted tissue and visualized as Gadobutrol enhanced regions\]- MR images acquired at different time points were evaluated by the respective investigator regarding the presence/absence of delayed enhancement at 5 - 20 minutes post injection in 16 myocardial segments (defined according to the American Heart Association). DE data were compared to the diagnosis "scar" derived from SPECT. The number of segmental assessments is defined as the number of segments with diagnosis "scar" assessed by the investigator.

Timeframe: Immediately within approximately 5 seconds after Gadobutrol bolus administrationPopulation: All participants in PPS with assessment for this outcome measure. Evaluation included all participants in the per protocol population with an assessment for this outcome measure.
Delayed enhancement: accumulation of Gadobutrol in infarcted tissue and visualized as Gadobutrol enhanced regions. Rest and stress perfusion MR and DE images were evaluated by 3 blinded readers for absence/presence of "scar" on perfusion MR and presence/absence of DE on MR for 3 myocardial regions representing the 3 coronary territories/arteries (LAD, LCX, RCA).
