Indications for coronary angiography

My dad was successfully resuscitated two weeks ago after his heart stopped.
Since then, he’s been recovering well—blood work, Holter monitor, and EKG all look fine.
We were really hoping they’d send him in for a coronary angiography to figure out if there's a blockage in a vessel that triggered the cardiac arrest.
But the doctor is saying there’s no need for an angiogram because the patient feels good and his labs are clear. And that's it. Just a dead end.
How is the decision actually made to go for an angiography? Is the doctor just trying to "cut costs" or is he playing games with us...
Not to mention, they are notoriously stingy with information here, so I’m stuck having to do my own digging...

Anybody?
My dad’s getting discharged tomorrow, and we still don't have a straight answer on what actually caused his heart attack.
It started with some pre-infarction stuff, then a mild one, then things got heavy... Honestly, every doctor seems to have a different theory.
But nobody is even bringing up a coronary angiogram or a scintigraphy. It's like they're acting like it's unnecessary because everything looks "fine."
Today he just did those tests on the treadmill, and that was supposedly it.
The doctor says the results look good and he can head home tomorrow.
I just want the best for my dad, but I can't shake this feeling that the healthcare system is cutting corners on him. Or anyone else, for that matter...

It’s honestly pretty tough to give any solid advice based on just a few lines posted here on a forum. From a strictly medical standpoint, you really have to nail down what actually caused the heart to stop, because a heart doesn't just quit on its own without a reason. That said, if his EKG and stress test both came back totally clean—and I’m assuming he had an echocardiogram done too, which hopefully looked fine—then maybe there just isn't a clear enough indicator to justify heading into a Cath lab to start messing around with the coronary arteries.

But then again... let's be real for a second. You can definitely feel those little cliques of "medical geniuses" hanging around the cardiology world. They all seem to have their own specific way of doing things, and if a doctor doesn't follow their particular playbook... well, good luck to them, I guess.
To make a long story short, if you feel like something is being missed or left out, go get a second opinion. Just try to stay level-headed about it. If you end up seeing someone at a high-end private clinic, you might find yourself stuck in an endless loop of expensive tests, new prescriptions, and constant follow-ups that never seems to end.

My dad got discharged from the hospital yesterday with these diagnoses:

Acute inferior myocardial infarction
Ventricular fibrillation
Post DC
Ischemic cardiomyopathy
Hypertension

Among other things, the discharge summary says:
"...the patient presented with an acute inferior myocardial infarction as the cause of current symptoms, and the arrhythmia was most likely precipitated by hypokalemia (K level at admission was 2.8)..."
"...Prior to discharge, a one-time stress test was performed at 50 W for 5 minutes, during which the patient remained free of angina and showed no significant ST segment changes..."
"...Follow-up with cardiology in 2 months, including a Thallium heart scan..."

So, what's next? It goes without saying we're all pretty terrified about whether that cardiac arrest will happen again, especially since the root cause isn't fully clear beyond that hypokalemia mentioned above (according to the doctor, those Lasix tablets might have been a trigger too...).
I just want the best for my dad; I feel like he deserves every single test that could actually help him.
Will the results of the Thallium scan show the actual state of his heart and indicate if he needs a coronary angiography? Assuming, of course, that there aren't any complications before then (early July).

Hey!

I might be heading in for a coronary angiogram soon, so I wanted to pick the brains of anyone who's been through it. Which parts actually hurt? I’m assuming it’ll just be the little sting from the local anesthetic, which would make sense, right? But then I saw this video where some surgeon was saying you can feel the scalpel incision too... maybe I'm overthinking it.

thanks!

Hey man! I actually just got back from my angiography at Magdalena in Krakow today... they did mine yesterday. A scalpel? There’s no scalpel involved, I don't know who told you that nonsense! There's really no pain at all. The little poke for the numbing agent is honestly less intense than getting a shot at the dentist... maybe feels like half a mosquito bite. It works instantly, and after that, you don't feel a thing. They go through the right groin, which you should shave the night before. You stay fully conscious the whole time... you can see your heart vessels on the screen and watch the doctor inject the contrast dye to check for any blockages. It's wild... they're maneuvering a thin catheter through your heart and you don't feel a single thing. You wouldn't even realize they're doing anything at all. You can chat with the doctor, though he's usually pretty busy talking to the technicians about the imaging angles and technical stuff. The procedure itself is super quick, just a few minutes... it's the prep that takes forever. They wheel you in, lay you down, cover you up, swab you with iodine, and so on. To be honest, lying flat was the hardest part for me because my lower back was aching, so they had to slide a pillow under me. Man, seriously, no scalpel... it's just a tiny 2mm puncture. But the catch is that since it's on a major femoral artery, you have to stay perfectly still for about six hours afterward. You aren't even allowed to roll onto your side until then. And you have to pee in a urinal. That downtime was the toughest bit for me... they put a pad under you so you don't soak the mattress, and since I have hair on my legs, they stuck those adhesive Holter monitor patches on me (they don't do it to everyone), plus the wires and everything. Plus, you're wearing one of those hospital gowns that ties in the back, which kept chafing and itching against my skin... I ended up getting so stiff that I actually stood up and tried to walk down the hallway later that evening. The nurses nearly lost it with me. Don't you dare try that, because you could puncture the artery and bleed out in minutes, or end up with a massive hematoma under the skin that requires surgery... sometimes you're looking at an emergency procedure within two weeks just to save your leg or even your life! Anyway, if they find a blockage, they'll pop in some stents right then and there, whatever is needed. If the blockages are too bad, they'll schedule you for a bypass, but that's a whole different conversation. I have one minor narrowing, so I'll just be managing it with medication. I need to get my blood pressure and weight under control because I have dilated cardiomyopathy, which means my heart is weakened. I wish they would have just given me a stent, but they say this is the better way and it isn't necessary yet. I trust them for now... don't listen to old wives' tales. Honestly, I'd rather go through five angiographies than have a single tooth pulled! Good luck!

It would seem logical that there shouldn't be much, but then I stumble upon some video where a surgeon is claiming that on top of the needle, you can actually feel the scalpel incision...

Thanks!

quietdrifter3 gave you a really thorough breakdown of the whole process. Usually, they order this when they need to confirm or rule out coronary artery disease.

I think I might be getting a coronary angiogram quite soon, and I was wondering if anyone who has been through it before could walk me through the painful parts. Is there actually any discomfort beyond the initial sting of the local anesthetic? It seems like it should be painless after that, but I happened to stumble upon a video where a surgeon mentioned that you can feel the scalpel incision too... so now I'm a little nervous.

thanks!

Well, let me jump in and share my own experience with you... honestly, the procedure itself isn't painful at all, though I wouldn't say it’s exactly "comfortable" either. It’s more just awkward and a bit unsettling because you have to lie there completely exposed on the table while they get everything ready for the doctors. Plus, you have to spend 24 hours lying flat on your back afterward, which means having to use a bedpan, which—if I'm being totally honest—was probably the hardest part for me personally. But truly, compared to the heart surgery I had to undergo later on, this was nothing. Best of luck to you!
