Had heart bypass surgery. Started chest pain. Taking nitrates. Are my arteries blocked again?

I recently had heart bypass surgery about 3 and a half months ago. Five weeks ago, I underwent a procedure called cardio version for an atrial fibrillation condition I developed one month after my surgery. However, about a week ago I started experiencing a recurrence of chest pains which I had prior to my heart surgery. I am currently travelling in China and now back to taking nitrates to relieve the chest discomfort. I thought the bypass already took care of the artery blockage problem. But now I feel back to square one. What could be happenning? Are my arteries blocked again? A blood clot perhaps blocking new arteries? Or is possible failure of grafted veins during the bypass? What is going on?

welcome to hcm
thanks for the query
coronary revascularization procedures do not guarantee complete relief of angina and recurrent chest pain after the procedure
the cause may be-(i) restenosis, (ii) disease progression, or(iii) incomplete revascularization iv)blockage some other artery distant to the initial one
there may be functional cause also .in these cases inappropriate vasoconstriction in the epicardial or microvascular segments occur. Typically,they present with symptoms of classic angina and may or
may not have changes consistent with ischaemia on stress testing.
my advice is consult your cardiologist once again
hope this information will be helpful to you
wish you good health
