I got a CAC scan for $75 just to catch anything crazy and I found out that I don't have a right coronary artery and also that I have 2 superior vena cava. My calcium score was 0 though so that's awesome.

One close friend died of a heart attack at 42 and another found a 95% blockage after his CAC scan came back north of 900 at age 40. I'd get it if it's available, the ability to catch certain catastrophic conditions is invaluable.
