The CT scan can give you a lot of information about your cardiovascular system. I just had one and again they say I have arteriolosclerosis, but my doctor says it’s not bad enough to do anything about.

Another test I’ve had is the echocardiogram

An echocardiogram, often called an "echo," which is an ultrasound test that uses sound waves to create moving pictures of the heart's structure and function. It provides detailed real-time images to help doctors evaluate the heart's chambers, valves, walls, and blood flow

You can also wear a Holter monitor for a day or a week to see how your heart is reacting. It gives the doctors a tremendous amount of information. It’s like walking around with an EKG on. I had one for a week recently and it showed a lot of issues but just very short term non-impactful issues.

I'm lucky enough to have stage CII heart failure along with Stage 4 PCa. I was referred to a cardio-oncologist to monitor heart function while going through PCa treatments. Along with what Jeff said as far as intermittent testing, I have regular blood tests to monitor for specific cardiac enzymes. Cardiology, urology, and oncology are all monitoring bloodwork for something on a regular basis. Can you say pin cushion? First name basis with phlebotomy.
