Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain and give you my opinion.
As you mention, you are a person diagnosed with
ischemic heart disease becouse you previously had an
infarction and you had a percutaneous intervention whith stents.
When a person whith this diagnosis complains for heart pain than we should exclude the possibility of active ischemic heart disease, meaning that might still be a problem whith coronary arteries, new ones or those treated before.
In these cases we recommend a strees test.If your doctor has programed you for another
angiography this means that he might have seen something in your
stress test that rises his doubt for what I mention before.
But, if your chest pains are more intense now in their severity or duration this means that the angiography should be prompt.
So, my opinion is that you should reffer this symptoms to your doctor, becouse this changes in the intensity of pains are reasonable to accelerate the angiography.
During this time don't make big efforts, take your medicament regulary and just meet your doctor.
Hope I was helpfull . Wish you good health.
Best regards, Dr.Ervina
