Since my husband got his stent, he is low on energy as well. He got his stent a year ago. After getting his stent he had chest tightness as well, same than before the surgery. We were very worried, had ER visits, appointments with our cardiologist, we had the feeling, they ignored us and didn’t take us serious.
The tightness disappeared after a few months.
We changed the cardiologist and now Tests are running to check if everything is fine to get rid of some medication.
I am not sure, we will see, but I can imagine, that maybe the medication has the side effects that causes this energy deficit?
Good luck for you and don’t give up, get other opinions.
Have a blessed New Year.

I agree with rainerhans on this. Sometimes you cannot be a passive patient, but an active advocate for yourself.

I remember thinking my cardiac issues were stress. When I went to see the physicians, they said they found nothing in the diagnostics which included radiology. But I knew something was happening. The only symptoms was the difficulty breathing and tightness in my chest. Had stress test a year earlier and passed with flying colors. They added a medication and was told to come back in a month. Six weeks later, they found a 99%+ blockage in the circumflex.

My point is your body is telling you something. Looking back, there was too much reliance on measurable test results in my case. I was my own worst enemy because I could tough it out. If my heart was not as strong as it is, I would have been in a cath lab weeks earlier.

I think a second opinion is in order. A fresh pair of eyes and ears may add a new perspective.

I hate to broach this subject, but keep an open mind about the psychosocial (stress) side of this as well. You have been through a lot. These are traumatic events. Regardless of the second opinion, be open to talking about your feelings as well. It's healthy and in my opinion, too many patients are not informed about the psychosocial needs after a cardiac event.

Best of luck to you. I am anxious to find out what happens if you ever wish to update us.

I too felt that way after a stent. After my first month I had an anaphylactic reaction to Clopidrogel (plavix). Leading up to the reactions I kept saying I think I am reacting. Low energy, weak legs, cold, no appetite, high anxiety. Everyone kept saying go see a psychologist. They kept saying that drug doesn’t do that. The kicker was I did keep having the odd good day so I believed them and kept taking it. I ended up being admitted to hospital and as I was in another city I had new eyes looking at me. The cardiologist and allergist there both said it is the Clopidrogel. Changed me to Birlinta and I am now back to my old self. When I told my cardiologist what happened he said “facts are facts, in my 30 years I have never seen that happen”.
