This study describes the results of @entity3693 testing in 100 consecutive @entity1 who underwent this procedure in a coronary care unit. All @entity1 had recently undergone coronary arteriography. A bolus injection of @entity3693 was administered at 5 minute intervals in the following doses (mg): 0.0125, 0.025, 0.05, 0.1, 0.2, 0.3 and 0.4. The criterion for a positive test was the appearance of S-T elevation greater than 1 mm. The test was positive in all 17 @entity1 known to have @entity5968 and in 18 (40 percent) of 45 @entity1 who had a history of @entity662 judged strongly suggestive of @entity5968 but who had no electrocardiogram recorded during @entity158 . Of 38 @entity1 with a history of @entity662 classified as not entirely typical of @entity5968 , only 1 (2.6 percent) had a positive test. Of the 64 @entity1 with a negative @entity3693 test, 47 had @entity662 and 25 had @entity390 but none had more serious complications. @entity943 accompanied S-T elevation in 18 of the 36 @entity1 with a positive test but occurred in only 4 of the 64 with a negative test (p < 0.0005). No @entity1 needed treatment with antiarrhythmic drugs. Four of the 36 @entity1 with a positive test had serious complications: severe transient @entity551 (2 @entity1 ), recurrent episodes of angina with S-T elevation (1 @entity1 ) and a @entity1188 (1 @entity1 ). Thus, @entity3693 testing is useful in @entity1 with a typical clinical history of @entity5968 but without an electrocardiogram recorded during @entity158 . In this study, a small but definite incidence of serious complications occurred during a positive test.
