As part of the first examination conducted in the Paris Prospective Study, 6 565 healthy males aged between 42 and 53 years underwent a submaximal exercise test on the bicycle ergometer. Ischaemic changes in the ST segment during or after exercise were noted in 6% of the tests. The predictive value of these changes for the development of ischaemic heart disease after 4 years has been assessed. The risk of sequelae is 3.2 times greater in this group than in the group with no changes. The variations of this risk with the precise timing of the onset of these ischaemic ST segment changes during the course of the test and with the type of heart disease have been studied.

The detection of coronary artery calcification by roentgenoscopy is an important hint at possible ischemic heart disease. By the advent of image intensification and magnification, this examination can easily be performed. If no calcifications are visible, an ischemic heart disease must not be excluded. The presence of calcification in the coronary arteries however strongly favours the diagnosis of arteriosclerotic heart disease. The roentgenoscopical search of coronary calcification is considered to be a valuable procedure since it is inexpensive, noninvasive and widely applicable.

In Finland the mortality from ischemic heart disease is highest in North Karelia and lowest in Southwest Finland. In this study the consumption of coffee has been measured from the total sales in the different areas of Finland to see if it correlates with the mortality from heart disease. North Karelia had higher coffee sales per inhabitant than Southwest Finland. This finding reinforces the view that carefully controlled dietary studies are needed to establish the role of coffee in the mortality from ischemic heart disease.

The relation between the apex cardiogram and changes in left ventricular pressure measured by micromanometer, and dimension measured by echocardiography, was studied in 12 normal subjects and 64 patients with heart disease. In 12 patients, the apex cardiogram was delayed with respect to simultaneous left ventricular pressure by 17 +/- 18 ms during the upstroke and 28 +/- 16 ms during the downstroke. In the normal subjects, changes in left ventricular dimension during the upstroke and downstroke of the apex cardiogram were small, amounting to 6 +/- 5 and 21 +/- 7 per cent total excursion, respectively. In 10 patients with mitral regurgitation, there was significant inward wall movement during the upstroke and in 10 patients with aortic regurgitation, significant outward movement during the downstroke, both reflecting valvular regurgitation. In 20 patients with ischaemic heart disease and segmental abnormalities on left ventricular angiography, apex cardiogram-echo dimension relations were abnormal in all, because of inward or outward wall movement during the upstroke, increased outward movement before the 'O' point, or abnormal inward movement during the downstroke. These disturbances were displayed by constructing apex cardiogram-echo dimension loops, which appear to be a sensitive means of detecting incoordinate left ventricular contraction, analogous to those between pressure and dimension.

Results are presented on a study of the blood coagulation system and some indices of serum lipids and proteins in 133 normal individuals and probands with ischaemic heart disease and their 681 relatives. The examination of the relatives of probands with different types of biochemical disorders revealed a similar biochemical background in the probands and the members of their families. The disorders in blood biochemistry in the probands were most similar in the parents, the children of the probands' siblings, and less distinct in more distant relatives (cousins, nephews and nieces, etc.), biochemical disorders similar to those of the probands being found in young persons (14-16 years old) and reappearing in several generations. The author concludes on the genetic heterogeneity of ischaemic (coronary) heart disease and underlying coronary atherosclerosis.

Studies were made for evidence of heart disease on 501 people aged 65 and more living at home; 22-4 per cent had clinical and/or electrocardiographic evidence of ischaemic heart disease. The prevalence of ischaemic heart disease increased with age, and was slightly greater in men than women. The frequency of ischaemic heart disease increased with increasing current cigarette consumption and with total cigarette consumption. There was no increase in relation to any of the following possible risk factors: systolic and diastolic blood pressure, blood glucose, serum cholesterol, skinfold thickness, percentage of ideal body weight. The survival over a 5-year period of all subjects with ischaemic heart disease did not differ significantly from that of all subjects together, but the mortality of subjects with ischaemic heart disease and an abnormal electrocardiogram was 1-5 to 2 times that of subjects in whom ischaemic heart disease was diagnosed on the basis of angina pectoris or past cardiac infarction, the electrocardiogram being normal.

1. A study was made of 34 cases (33%) of myocardial infarction trans and immediately postoperative which occurred in 11,210 surgical interventions with and without extracorporeal circulation. 2. This presents a statistical relation of the frequency of myocardial infarction in realtion to the heart disease acquired with or without extracorporeal circulation with the mitral, aortic, and double prosthesis of the mitral and aortic valves. A correlation was also made with the ischemic heart disease subjected to revascularization. The same analysis was carried out in the congenital heart disease with or without extracorporeal circulation. 3. In all cases the antecedents, precipitating factors, and the clinical picture were studied and in 12 cases the necropsy was analized. The principal finding was transmural myocardial infarction with electrocardiographic proof and serial enzymes. 4. The group was divided into two sub-groups; Group "A" with acute myocardial infarction transoperative, and Group "B" with acute myocardial infarction in the first eight postoperative days. The electrical and mechanical complications were analized. 5. A correlation was made of the causes of mortality related to the type of congenital or acquired heart disease with or without extracorporeal circulation. 6. The frequency of this entity was studied with the total time of aortic clamping, and the complications such as the low cardiac output syndrome, rupture of the wall, aneurysms, acute pulmonary edema, and with the disturbances of rhythm and conduction. 7. The presence of 33.3% of normal coronaries in these of necropsy was emphasized. 8. The importance of the coronary profile of this group in relation to the consequences of a stress from anesthesia, surgery, extracorporeal circulation, and aortic clamping is mentioned. 9. The diagnostic parameters such as arterial hypotension with or without the low cardiac output syndrome, enzyme levels, and the action of the potassium ion are mentioned. 10. An analysis is made of the possible etiological factors of the precipitation of the myocardial necrosis in the cases with normal coronaries and those in which there was no important obstruction of the coronary macrocirculation. 11. In the subgroup "A" it was found that the frequency of myocardial infarction was less than in the subgroup "B", but there was greater mortality in group "A". The possible causal factors are analized.

Polarcardiograms (PCG) derived from xyz leads of the Frank electrocardiogram (ECG) were recorded in the supine position in 1264 initially healthy middle-aged Chinese men who had been under continuing medical surveillance and were re-examined seven years later. Polarcardiographic criteria for myocardial infarction (MI) were demonstrated in 97 men (7.7%), but only 15 of them showed diagnostic Q waves in the electrocardiogram (ECG). Polarcardiographic criteria for MI were independent of age, but ranged from 4.3% in 464 apparently normal men to 38% in 21 men with manifestations of ischemic heart disease. The possible association of polarcardiographic criteria and a history of smoking was limited to those with clinical evidence of heart disease. The "false positive" rate of 4.3% in clinically normal men was similar to that reported in younger Canadians and in Cretan population samples.

Two cases of lepromatous leprosy are presented with heart disease, one with cardiomegaly and the other with ischaemic heart disease. It is very difficult to say whether heart disease was due to any other cause associated with leprosy or due to leprous affection of myocardium. As there are no references in the literature regarding these, two cases are presented as problem cases.

Moderately alcohol-discordant male twin pairs, aged 45-65 years, have been examined with respect to ischemic heart disease (IHD) and associated factors. No conclusion can yet be drawn with regard to manifest or subclinical IHD, while significant disparities were found with regard to systolic and diastolic blood pressures, high cigarette consumption, hyperglycemia, and serum cholesterol; the greater number of findings of pathological values were found in the high alcohol-consumption as compared to the low alcohol-consumption cotwins. These findings offer a possible explanation for the increased number of reports showing a connection between high consumption of alcohol and occurrence heart disease.
