Thanks for posting,
It is a good thing to be worried about your father's condition.
Yes there is a difference is a difference in their pathogenesis, also how they affect the artery and a slight difference in their out come.
Circulatory collapse may involve either cardiac circulatory collapse (affects the vessels of the heart such as the aorta and is almost always fatal) or peripheral circulatory collapse (which usually involves outlying vessells of the heart). Your father seemingly has the former (peripheral) which involves specific failure of the circulation like the case of your father was right coronary artery has failed or collapse. Peripheral collapses usually involve abnormally low blood pressure and result in collapsed arteries and/or veins, leading to oxygen deprivation to tissues, organs, and limbs. Acute collapse can result from heart failure and causes the collapse of the primary vessels of the heart collapsing, perhaps combined with cardiac arrest. There are several medical and non-medical condition that can lead to circulatory collapse.
Where as artery block is simply the blockage or obstruction of the coronary artery by foreign body or thrombus or emboli or artheromatous plaque or wall thickening etc. This is generally termed coronary artery diseases which can lead to angina pectoris, heart attack, stroke etc.
It is possible for your father to manifest any cardiac symptoms if the condition is still mild.
Cardiac stress test (or Cardiac diagnostic test) is a test used in medicine and cardiology to measure the heart's ability to respond to external stress in a controlled clinical environment. The meaning of your father's test results depends on the reason for the test, his age, and your history of heart and other medical problems. It may be hard to interpret the results of an exercise-only stress test in some patients.

Hope this answers your question.
