SEVERE or intractable chest pain, associated with sweating, vomiting, precipitate fall of arterial blood pressure, fever, and evidence of shock or collapse, clearly indicates a diagnosis of acute myocardial infaretion. In marked contrast is the entity of angina pectoris, with its paroxysms of chest pain after effort, typical radiation of pain into the arm, feeling of viselike constriction in th...

The circulatory adaptation to arm and leg exercise was studied with stepwise increased work loads in 10 patients with signs of coronary artery disease. Both arm and leg exercise elicited angina pectoris in all patients. Anginal pain appeared at the same level of pressure-time per minute (PTM) in the two forms of exercise, but at a smaller work load and a lower pulmonary oxygen uptake during arm...

The coronary arteries supply the heart muscle (myocardium) with oxygen and nutrients. According to current scientific views, low-grade inflammation causes lipid deposits in the artery wall, which may create plaques. This condition, atherosclerosis, occurs predominantly in larger arteries, including coronary arteries. The subsequent narrowing of the artery restricts blood flow to the myocardium,...
