Can we worsen our condition (in CAS or CMVD) if we push through the pain of angina?

Angina associated with severe coronary stenosis is triggered by exercise and relieved by rest. Angina associated with CAS or CMVD is not precipitated by excess cardiac work but by transient impairment of myocardial perfusion. But the common background is always cellular ischaemia and therefore it is difficult to imagine that pushing through might be irrelevant.
