RESUMEN
1. Study of a group of 50 patients suspected to have coronary artery disease. This is a complement to a previous study concerning "definite" coronary patients. 2. The method followed consisted in cross-examination of the files by three observers in order to separate the subjects who seemed really affected by coronary artery disease. This treble examination led to a rather restrictive selection. To facilitate the study, the patients were subdivided into 4 groups: patients with arterial hypertension, with diabetes mellitus, with cardiac failure, with a heart disease and miscellaneous patients. 3. The study of the 20 files which were discarded was peculiarly interesting as it provided the opportunity to underline the differential diagnosis either with common diseases (left ventricular overload, heart block, brain vascular accident), or with more specific diseases for Black Africa (endomyocardial fibrosis, aneurysm of the left ventricle, cardiomyopathy). In that respect, it is underlined that, in the absence of any anatomical or functional disease, the electrocardiogram of the healthy Black is identical to that of the White. 4. Study of the 30 patients considered as coronary made it possible to underline aetiological and epidemiological factors, although some are still lacking. However the facts observed could be compared with those reported in a previous work concerning 45 "definite" coronary patients. The overall documents thus gathered in 75 patients suggest that the African candidate to coronary artery diseases resembles his Occidental homologue, but that he might have kept a traditional diet.
