I was recently told that I have calcium developing in my main heart artery! What does that mean and what can I do? I had weight loss surgery 2 yrs ago

Marker. Calcium may be a marker of blockage developing. Best plan is to be followed by cardiologist who will assess all your risk factors and suggest ways to minimize risk of allowing coronary disease to progress. Will also allow creation of testing schedule to follow for ongoing evaluation. Also recommend looking into things you can do to lower your riskd on your own as well, like not smoking .
