Cardiac pain has long been of clinical interest, but not until the past decade has it been subjected to laboratory investigation. Although Allbutt's¹ theory of the aortic origin of angina pectoris was once widely accepted, recent experimental evidence strongly points toward the cardiac origin of pain. Sutton and Lueth² have shown that compression by means of a ligature on coronary vessels in the unanesthetized dog results in pain characteristic of angina pectoris. Their studies have been confirmed by White, Garrey and Atkins³ and by Katz and his associates.⁴ All these authors have agreed that the fundamental mechanism initiating pain is a chemical factor produced by impaired coronary circulation. In essence, this contention is the basis of Lewis'⁵ theory that myocardial ischemia is the cause of cardiac pain. From the aforementioned studies it is generally inferred that the mechanical factor is of secondary importance in producing . . . [Full Text PDF of this Article]
