OBJECTIVE: Assessment of the clinical applicability of DS-MRI for the detection of @entity741 and @entity296 . DESIGN: Prospective. METHOD: In the period from 1 November 1999 to 31 October 2000, @entity1 with suspected @entity453 who could not be studied by means of conventional bicycle ergometry underwent breath-hold DS-MRI (1 Tesla) 4 days after cessation of anti- @entity63 medication. Three left ventricular short-axis planes were examined for the occurrence of disorders in wall movement during infusion of increasing doses of @entity452 (10, 20, 30 and 40 micrograms/kg/min). Temporary recovery of wall thickening in a previously diminished or non-contracting segment under 5 micrograms/kg/min of @entity452 was considered proof of viability. Development of hypo-, a- or @entity910 at higher doses of @entity452 was taken to indicate @entity63 . If the DS-MRI test was positive for @entity63 , coronary angiography was performed. If indicated, this was followed by revascularisation. If DS-MRI did not reveal @entity63 , the @entity1 was seen at the outpatient department. RESULTS: Of the 100 @entity1 (62 @entity1 and 38 @entity1 with an average age of 62 years, SD = 12) subjected to DS-MRI, 95 yielded results that were suitable for diagnosis. Of the 42 @entity1 with DS-MRI scans that were considered positive for @entity63 and in whom coronary angiography was subsequently performed, 41 had such coronary abnormalities that revascularisation was indicated. One @entity1 was false-positive. All 53 @entity1 with non- @entity63 DS-MRI scans were followed-up for 11-23 months (mean 17 months). One @entity1 died suddenly 2 weeks after the MRI-test. The other 52 @entity1 did not experience any coronary events nor @entity1164 . The predictive value of a positive DS-MRI scan for @entity63 was 98% and the predictive value of a negative DS-MRI scan was also 98%. CONCLUSION: DS-MRI is a safe diagnostic method for the detection or exclusion of @entity741 and viability in @entity1 with suspected @entity453 .
