In this episode of Better with Dr. Rock: Outside the Box Healthcare, Dr. Matthew Ketman shares a quick but powerful message about a simple test that could save lives: the coronary artery calcium screen. It’s a fast, low-dose CAT scan that checks for plaque buildup in your heart’s arteries—something that could point to hidden heart disease long before symptoms show up.

Dr. Rock explains who this test is for, highlighting people with a family history of heart disease, high cholesterol, or other risk factors—even if they feel totally fine. He’s clear that it’s not meant for those with current symptoms like chest pain, but for folks who want to be proactive about their heart health.

He also breaks down some of the limitations, like the chance of false positives, but stresses that it’s a great tool when used in the right situations. As always, Dr. Rock encourages listeners to stay curious, talk with their doctors, and keep looking for ways to take control of their health—before problems start.
