RESUMEN
To examine correlates of individual differences in the degree of right hemispheric dominance in the perception of facial emotion, 51 medical students completed the Levy Chimeric Faces Test and an independent measure of differentiation and complexity in the processing of emotional information, the Levels of Emotional Awareness Scales. A strong positive correlation was observed between the two measures, especially when variance due to verbal ability was removed and native English speakers only were included. These results suggest that as right hemisphere dominance in the perception of facial emotion increases, the ability to perceive complexity during the processing of emotional information increases.

Angiographically documented coronary artery disease (CAD) can progress. Although progression itself is frequently recognized in patients who have undergone repeat cardiac catheterization, its prognostic significance remains unclear. To evaluate the influence of progression on survival, 313 patients with CAD who underwent catheterization twice (39 +/- 25 months apart) were followed for 3 to 129 months (mean 41 +/- 30) after the second angiogram. At the time of the second angiogram, 21, 91, 113 and 88 patients had 0-, 1-, 2- and 3-vessel CAD, respectively. The mean ejection fraction (EF) of the group was 55 +/- 13%. Progression was noted in 139 patients (44%). Of the 313 patients, 33 died and 39 had acute myocardial infarction (AMI) during follow-up. Four-year survival was estimated at 94% and 83% in the nonprogression and progression groups, respectively. Progression was predictive of survival by (univariate) long-rank test (p less than 0.01), but only EF (p less than 0.001), number of diseased vessels (p less than 0.01) and percent stenosis in the left main coronary artery (p less than 0.05) were independently significant by (multivariate) Cox regression analysis. Four-year survival without AMI was 89% and 73% in the nonprogression and progression groups, respectively. Progression was related to survival without AMI (p less than 0.001) by log-rank test. Cox regression analysis provided 3 independent predictors of survival without AMI: number of diseased vessels (p less than 0.01), progression (p less than 0.01), relative risk = 2.28) and EF (p less than 0.01). Results were similar when analyzing only the 39 AMIs.(ABSTRACT TRUNCATED AT 250 WORDS)

Successful use, in 650 patients over a period of two years, of a percutaneous femoral technique of selective coronary angiography is described. This technique is carried out with the use of mouldable, manually preshaped polyethylene catheters. Preparation of the material and the different steps of the technique are discussed. Excellent flexibility and plastic memory of this catheter material allow easy, rapid and consistent percutaneous insertion and removal of catheters and intubation of the coronary arteries.
