Typical Angina: If a person has obstructive coronary artery disease, that is a narrowing/stenosis/"blockage" of 70% or more in one of the vessels, one would generally expect that at a certain workload/"heart rate" range, that the person would be expected to have angina. An exception would be in the case that the person develops small blood vessels around the blockage; this may change the hr that angina occurs.
