Thank you for both replies. I forgot to mention that I wore a Holter monitor twice. Each time for 24 hours. While wearing the monitor, I did experience heart palpitations, as I do every day. The cardiologist said nothing abnormal was picked up. The palpitations feel like the heart is beating rapidly but not irregularly. He still thinks they're benign, but every day for almost 2 years is a long time.

But my main concern is the extensive plaque buildup. I do occasionally feel very mild (1 on scale of 1-10) chest discomfort, especially when I wake up and try to go back to sleep. Other than that, no symptoms.

I do have an appointment with the cardiologist later this month. But it's an appointment I set up because I have so many questions. There would be no further follow up if I hadn't requested the appt.

But to be fair, these tests have been done:

Cardiac Catheterization

EKG 12 or more leads

X-ray chest, PA and lateral

Echocardiogram stress test, CV

Transthoracic echo

CT heart scan

Treadmill stress test

Holter Monitor

I don't know if there are any other tests I should request?

I am interested in the answers to these questions:

Given my low BP #'s, is it a mistake for me not to take Bisoprolol as the Dr. suggested?

With such a high calcium score what does it mean that I don't have more symptoms, like being out of breath when I exercise or experiencing chest pain. As I said I do have occasional very mild chest discomfort.

Also, what does it mean that I have such a low BNP (40) with such a massive calcium buildup? Since I'm 71, Dr thinks I've had the buildup for many many years.

Finally, is it unusual to have such a very low calcium score (8.7) with such a massive calcium buildup?

I would like to hear from @heycal, @calongi1000, @alaskat

Thank you for your time. I really appreciate it!
