What would you say are measurable factors (signs) objective of angina pectoris?

Signs of angina: Angina pectoris is chest pain due to coronary supply/demand mismatch (blockage in coronary arteries with reduced flow to the heart muscle). Objective signs of this state may include: ECG changes (st depression, st elevation, inversion of t waves), wall motion abnormality on echocardiogram, or abnormal cardiac enzymes (if angina is prolonged, heart damage occurs).
