It is observed from this study
that angina pectoris and coronary thrombosis
are the different phases of the same process
being caused by anoxaemia of heart muscle.
The underlying factor in both the conditions

excluding the precipitating factors is the
same i.e. atherosclerosis of coronary arteries
Atheromatous changes in angina pectoris
however are more or less of a uniform nature,
resulting usually in narrowing of the lumen
of these vessels, whereas in coronary
thrombosis the changes are generally of a
patchy type with or without much narrowing
of the caliber of coronary arteries. The
precipitating factors no doubt are different,
but while coronary thrombosis is caused in a
person with Sclerotic coronary arteries at
rest, Angina pectoris results in the same
individual in excitement and with exertion
