About: If the false anginas recognize different causes and pathogonies (distension of the cardiac cavities through generalized arterial spasms or vaso-motor troubles, dilatations of the heart consecutive to gastro-intestinal affections, neuralgia of the cardiac plexuses, etc.), true angina, on the contrary, explains itself by an invariable pathogony; it is due to the lesion of the cardiac arteries, to their sclerosis, to their contraction; it is most frequently the result of an aoritis, upon the condition that the latter intersects and partly closes the opening of the coronary arteries (pericoronary aortitis), and the paroxysms of angor are provoked by a temporary cardiac ischaemia, a veritable intermittent claudication of the heart, as M. Potain so judiciously remarks, who compares the products of the anginous attacks to what happens in the case of intermittent claudication of the extremities through incomplete obliteration of the iliac arteries.     Permalink
