RESUMO
The accuracy of "Sandoz Pressure System", in comparison with the mercury sphygmomanometer, was studied in 171 patients in 2 centers. The correlation, as estimated for 657 pairs of measurements, was excellent: systolic and diastolic coefficients were r = 0.986 and r = 0.940 respectively. The individual difference is less than or equal to 5 mm Hg for 90% of the systolic values and 82% of the diastolic values. The ambulatory reliability is demonstrated for 300 profiles, of which 279 (93%) are complete. Of 7902 determinations, 59 (0.75%) were deleted because considered to be incorrect.

Stenosis of the left main trunk was revealed by selective coronary angiography in 15 patients among the 567 who were investigated (2.6%). No case of total occlusion was observed. There was no fatality due to the procedure. As a rule other coronary vessels also show atheromatous lesions. Five patients were not operated: 3 died (60%) after a mean survival period of 14 months following angiography. Among the 10 others who underwent surgery there was no operative mortality, but 2 patients died in the postoperative period (20%). The 8 survivors have been followed for a period ranging from 8 to 61 months (mean: 36 months). All are still alive and much improved clinically. Once the diagnosis of left main trunk stenosis has been established, early surgery should be considered.

600 selective coronary angiographies were performed in 559 patients, using Judkins preformed transfemoral catheters. One fatality was deplored (mortality: 0,17 p. 100). 15 cardiac complications were observed 2,5 p. 100), 10 of which were severe but rapidly corrected arrhythmias. Among these 559 patients 495 were clinically cases suffering from probable or certain coronary heart disease. 88 p. 100 of this group were men. Selective coronary angiography revealed stenosis with decrease of at least 50 p. 100 of the lumen in over 80 p. 100 of the cases. The anterior descending was the most frequent site of stenosis. In the majority of cases, and especially in men, two or several vessels were diseased. There is some relationship between the development of collateral circulation and the extension of coronary disease. In one third of the cases, ventricular function, assessed by measurement of the ejection fraction was impaired.
