In 34 patients with coronary atherosclerosis a pacing test was performed with measurement of the lactate, glucose, potassium and inorganic phosphate coronary arterio-venous differences. Eighteen of these 34 patients felt no pain during the pacing test. In this group of asymptomatic patients, there was no significant change of the lactate, glucose, potassium and inorganic phosphate myocardial extraction. In the 16 patients who felt an anginal pain during the pacing test, there was a significant myocardial production of lactate, but the myocardial loss of potassium and inorganic phosphate was not continuously statistically significant. Myocardial extraction of glucose during the pacing-induced angina did not increase. Although, in some patients, both the potassium and the inorganic phosphate might be used to assess a condition of myocardial ischaemia, the lactate remains the best metabolic criterion for pacing-induced ischaemia.

Report of one case of Prinzmetal variant of angina pectoris with a typical clinical and electrocardiographic picture in a man aged 87. Severe arrhythmias resulted in death of the patient. On autopsy a moderate narrowing of the anterior interventricular artery was demonstrated. In that relation, a review of the literature on the anatomical lesions and coronary arteriographic data of Prinzmetal angina was performed. It showed that in some cases Prinzmetal angina could be observed while the coronary artery lesions were very moderate. The pathogenesis of these facts was discussed.

The study of various myocardial metabolic substrates in basal conditions and in the course of an atrial pacing test in two groups, one control, and the other including angina pectoris in patients with sound coronary arteries, provides the confirmation that the only valid metabolic criterion for acute myocardial ischaemia in man is represented by the decreased extraction or production of lactates. The sugnificance and the specidicity of this parameter is discussed.

Report of the case-history of a 66 year-old woman in whom the diagnosis of ventricular aneurysm was reached in 1958 during a systematic X-ray examination, while the electrocardiogram suggested a lateral-wall infarction with no anginal pain. After fifteen years of a practically asymptomatic course there were practically uninterrupted attacks of ventricular tachycardia. Coronary angiography and left ventriculography excluded the hypothesis of an aneurysm and suggested the diagnosis to cystic tumour of the left ventricle. A voluminous hydatic cyst was removed surgically. Ventricular arrhythmia did not recur since.

One hundred and twenty patients went through a complete cycle of physical training. Eighty seven of them were recovering from recent myocardial infarction, eighteen had angina pectoris and fifteen were recovering from operation of aorta-to-coronary by-pass. Physical training was considered to be contra-indicated in the presence of evolutive angina pectoris, obvious signs of cardiac failure and a voluminous ventricular wall aneurysm. Severity of the anginal pains and intensity of the coronary artery lesions were not contra-indications. In all the cases, there was a decrease of the number and intensity of the pains while the extent of physical performance increased. The psychological effect was remarkable. Comparison between the maximal exercise tests before and after re-education showed an improvement of the cardio-circulatory function, as evidenced by a decreased cardiac rate, of the blood pressure and of the degree of the downward displacement of the ST segment for efforts of equal intensity.

A myocardial revascularisation procedure was carried out on 68 patients with obstructive atheroma of the coronary arteries associated with severe angina pectoris. In 58 cases a total of 97 vein grafts were used, and in 10 cases the internal mammary artery was anastomosed to the anterior descending artery (using a vein graft in 5 of them). Before operation the patients had selective coronary arteriography, and a maximal exercise test using a bicycle ergometer. Three months postoperatively the patency of the coronary by-pass was checked, and a further exercise test completed. In the exercise test the criteria were the appearance of angina pectoris, improved performance (measured by the duration of exercise, the maximal power, and the heart rate at the end of exercise), and improved ECG findings. These criteria were correlated by the patency of the graft or grafts as noted at arteriography. There was no pain on exercise in 55 patients (81 per cent), the performance improved in 37 (54 per cent), and the ECG findings improved in 50 (72 per cent). At angiography, 34 patients (50 per cent) had a completely patent by-pass (group I), 31 patients (45.5 per cent) had at least one patent graft (group II), and 3 patients (4.4 per cent) had no patent graft (group III). Group I corresponds to 31 good or very good results and to 3 states on non improvement; group II contains 22 good results and 9 states of non improvement; group III corresponds to 3 states of non improvement. Exercise demonstrates the results of myocardial revascularisation surgery; the correlations between these results and those of graft patency justify its use in surveillance of coronary patients who have been operated. Exercise tests show that the best results are obtained in patients with severe functional disturbances and whose ventricular cinetics have remained sufficient.

Based on the study of 25 cases, the authors define menace syndrome in the anterior descending artery (ADA) according to three criteria: angina of recent onset and rapid development, a major disorder of repolarisation in the anterior part of the heart, and a tight proximal stenosis of the ADA. Of seven patients who could not undergo surgery, three sustained anterior infarctions, and three died after 30 days. 18 patients underwent surgery to revascularise the myocardium by anastomosis of the internal mammary artery to the ADA; 13 of these were carried out as urgent procedures (an average of 26 hours after coronary arteriography). The functional results were excellent, and all of the internal mammary anastomoses studied at 6 months (9 cases) were patent. This study has shown that menace syndrome of the ADA is a surgical emergency, and that a procedure to anastomose the coronary arteries should be carried out immediately after coronary anteriography.

The many important features of selective cine-coronary-arteriography to show the coronary arterial tree are demonstrated in the study of 130 such investigations carried out in patients with unstable angina. Cine-coronary-arteriography shows up the extent and location of obstructive atherosclerotic lesions. Ventriculography, together with measurement of ventricular pressures, gives information about the function and kinetic status of the left ventricle. These two investigations which do not, in our opinion, carry a greater risk in these cases than in cases with chronic angina, allow a precise diagnosis to be made. The early discovery of major lesions before infarction has occurred allow conclusions to be drawn about the prognosis and the appropriate treatment.

21 chronic anginal patients (AP), 23 patients with an overall number of 37 aorta-to-coronary artery by-passes (ACB) underwent a regular physical training (cycle, quick or uphill walking, gymnastics). The patients were compared to themselves in the course of a calibrated effort test, performed until angina occured or the maximal cardiac rate reached.

A great number of studies devoted to coronary artery anastomoses on the experimental animal or on post-mortem material, while the in vivo studies are relatively rare. The results of these studies are often contradictory, and many questions are still unresolved concerning the part played by the anastomoses in natural history of coronary artery atheroma. On 140 patients, all suffering from angina due to coronary atheroma, a study of the anastomoses visible on coronary arteriograms was undertaken, together with a statistical analysis of the various correlations between the presence or not of coronary artery anastomoses and the various criteria, anatomical, clinical and electrocardiographic.
