Clinical and angiographic correlates and prognostic significance of the coronary extent score.

The clinical and angiographic correlates and the prognostic significance of the "coronary extent score" in a consecutive series of 313 patients who were catheterized twice were studied. The extent score was defined as the number of 5 to 75% stenosed segments in a 15-segment coding system. The extent score was higher in subgroups of patients with new onset angina at the time of the first angiogram (4.3 +/- 2.4 vs 3.3 +/- 1.9, p less than 0.01), unstable angina at the time of the second angiogram (4.0 +/- 2.0 vs 3.3 +/- 1.9, p less than 0.05) or multifocal progression from the first to the second angiogram (4.0 +/- 2.1 vs 3.3 +/- 1.9, p less than 0.01), suggesting that it is an index of active coronary artery disease. The extent score did not correlate with the number of diseased vessels (r = 0.03), the ejection fraction (r = 0.03), the Friesinger score (r = 0.04) and the Gensini score (r = -0.07) (difference not significant for each). Cox's model was fit to the survival data recorded on a prospective basis after the second angiogram. Independent predictors of survival were ejection fraction (p less than 0.001), extent score (p = 0.001), number of diseased vessels (p = 0.01) and percent of left main luminal stenosis (p less than 0.05). The extent score was also an independent predictor of myocardial infarction and unstable angina. Thus, the extent score, an index of active progressive disease, is an independent predictor of mortality and cardiac events in patients with coronary artery disease.

Segmental influence: the case of educational and occupational significant others.

This research examines the scope of influence exerted by the occupational and educational significant others (SO's) identified by a sample of 142 high school youth in an attempt to determine the extent to which this influence is segmental. The data show that the influence of most significant others is specific to either educational or occupational ambitions suggesting that these are fairly distinct realms for adolescents. Variations by sex of student for ego and relationship of other to ego are noted, and the implications of the pattern of SO influence for female achievement are discussed.

[Compulsory internship in diagnostic radiology in the 5th year of medicine at the University of Montreal].

Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine. To this end, the committee formulated the objectives, content, evaluation system, and pedagogical methods to be used in those courses. The 25 self-teaching modules, together with the observation and practical interpretation of radiology sessions, proved highly useful in solving the initial problems, and were of particular interest to the students.

Undergraduate radiology clerkship: the Universite de Montreal program.

At the Université de Montréal, a four-week rotation in radiology is part of the core curriculum for students in their fifth and final year of medicine. The objective of this undergraduate radiology clerkship is to prepare the future physician to use efficiently the resources of radiology and nuclear medicine in patient care. Specific goals and methods used to achieve them are described and analysed.

Clinical, angiographic, and hemodynamic findings in patients with anomalous origin of the coronary arteries.

Clinical and angiographic features of 31 patients with anomalous coronpary artery origin are reviewed. Of 17 aberrant circumflex arteries from the right sinus of Valsalva or artery, each was retro-aortic, six atherosclerotic, and seven irrigated a small area of myocardium. Of seven anomalous right coronary arteries from the left sinus of Valsalva or artery, each was ante-aortic and two atherosclerotic. Aberrant origin of the circumflex or right coronary artery was a benign anomaly. The proximal course of seven aberrant left coronary arteries from the right sinus of Valsalva or right coronary artery was related to clinical events. The anomaly was best demonstrated in the lateral view. In five cases, coronary blood flow during exercise and myocardial metabolism during pacing were assessed. Two had had a previous infarction with nonatherosclerotic arteries. Exercise coronary blood flow was normal in four and low in one patient. Pacing resulted in lactate production in two with atherosclerotic and one without atherosclerotic arteries. We conclude that anomalous left coronpary origin from the right sinus of Valsalva can result in significant myocardial ischemia and infarction.

Aberrant course of the left anterior descending coronary artery assoicated with anomalous left circumflex origin from the pulmonary artery.

We have presented a two year nonoperative follow-up of an asymptomatic 14-year-old girl with an unusual anomaly of the coronary arteries. Systolic and diastolic murmurs heard preoperatively did not change following severance of a patent ductus arteriosus. Postoperative selective coronary arteriography revealed (1) anomalous orgin of the left anterior descending artery from the right aortic sinus of Valsalva crossing between the aorta and pulmonary artery, (2) aberrant circumflex artery orgin from the pulmonary artery and (3) collaterals from the left anterior descending and right coronary arteries to the circumflex artery. This combination of coronary anomalies has never been described previously.

[Profil and course of complete obstruction of 3 coronary trunks].

In a series of 4000 patients subjected to coronary arteriography, 12 were found to have complete obstruction of three major coronary arteries, an incidence of 0.3 p. 100. The clinical manifestations did not follow a typical pattern. Although 9 had a previous myocardial infarction or heart failure, only 6 were incapacitated by angina or dyspnea. Except for one patient, the resting EKG was abnormal. Half had a markedly elevated resting end-diastolic pressure and gross abnormalities of left ventricular contraction. In spite of surgery in 7, with only one operative death, a yearly mortality rate of 20 p. 100 has been recorded during a 3-year follow-up. This extremely low survival rate, the severe functional impairment in half of the survivors, and the subsequent high yearly mortality rate, all suggest that surgery be considered before complete obstruction occurs in patients with significant disease of three coronary arteries. A 10 p. 100 yearly mortality rate reported in patients with triple vessel obstructions, also favours surgery in such patients with the hope of prolonging life, providing good distal runoff and satisfactory left ventricular contraction are present.
