In order to investigate whether stressors could induce @entity943 or @entity741 in the postinfarction period, 130 @entity1 with recent @entity583 (1-2 months after the acute episode), after drug washout, were exposed to two stressors in a random sequence. Mental arithmetic and Sacks test (30 incomplete sentences with high emotional content) were used for 3 min, followed by 5 min recovery. Ninety % of the @entity1 underwent an exercise test and 73% a 24 hour ambulatory monitoring in the same conditions. @entity943 occurred respectively in 21%, 26% and 86% of the @entity1 during mental stress, exercise test and ambulatory ECG monitoring. The @entity943 score (Italian Lown modified classification) was greater than or equal to 40 in 2% of the @entity1 during mental stress and in 39% in the ambulatory ECG. Only 3 @entity1 (2.3%) showed @entity308 greater than or equal to 1mm during mental stress vs. 30.7% during exercise. The double product threshold for ST-segment shift was reached or exceeded during mental stress by 22% of the @entity1 . The increments in heart rate and blood pressure were independent from each other, and similar in the two stress tests. Only the heart rate was slightly higher during mental arithmetic (p less than 0.01). In conclusion, the utilized short-lasting stressors were poorly effective in inducing @entity741 and @entity943 in @entity1 with recent @entity583 . It is suggested to avoid the generalization of these results to @entity1 with different pathophysiological conditions, taking on account the methodological limits of the study.
