A study of the distribution of the various risk factors for coronary artery disease as a function of the age and sex of a homogenous population of 316 patients has brought to light the following findings: -- These was found to be a greater incidence (statistically significant) of hypertension disorders of glucose metabolism obesity and hypercholesterolaemia in the females, and of tobacco consumption (cigarettes) and, to a lesser extent, of hypertriglyceridaemia and of gout in the males; -- The females who 'tot up' risk factors have their myocardial infarction at a greater age than the males -- The risk factor which separates the two sexes in the consumption of cigarette tobacco. These findings agree with those already in the literature.
Fifty five anatomo-clinical cases of patients who died of a recent myocardial infarction were divided into two groups according to existence of a complete block of one of the branches of the bundle of His, which occured at the same time as the myocardial necrosis: group A: 14 cases comprising 13 complete right blocks and only one complete left block, or absence of intraventricular conduction disorders: group B: 41 cases. The macroscopic anatomical study separated the two groups: in group A there was a very high frequency of healed posterior infarction, extensive recent anterior infraction, transeptal through the anterior and upper half of the interventricular septum by occlusion of the anterior interventricular artery in its proximal segment, above the origin of the second anterior septal artery, associated to severe stenosing lesions of the other coronary trunks, in particular the right coronary artery.

The data of the macroscopical-anatomical examination of 14 cases of cardiac rupture (10 women, 4 men) complicating acute myocardial infarction were compared with those obtained at autopsy, with the same protocol, in 31 cases of myocardial infarction which resulted in death before the 30th day after the onset. Many anatomical facts separated both groups from each other (size, aspect, limits of myocardial necrosis, state of the coronary arteries). Eventual surgical conclusions might be drawn from this study.

Mitral valve prolapse is usually a benign affection, and yet but rather seldom, severe rhythmic troubles and even a sudden death may happen. The authors relate an observation about a seventeen years old young man presenting syncopes caused by ventricular fibrillation fit. The existence of a mitral valve prolapse is demonstrated by phonomecanogram and specially by echocardiogram which shows a telesystolic depression of the small valve. The observation is followed by commentaries about the frequency and clinic of Barlow syndrome. The rhythmic troubles liable to accompany this mitral damage are analysed and so is the evaluation of the risk of a sudden death by ventricular fibrillation.
