@turquoise-- That's a bad idea. A blocked artery is really dangerous and not just because it will prevent blood flow to important parts of the body. It's also dangerous because the built up cholesterol can dislodge from where it is and move in the blood stream and block other arteries and veins.
You really ought to have tests done, there is no guarantee that people will get serious side effects when they have a blocked artery. Some people don't get any side effects. Early diagnosis and blocked artery treatment is key to preventing heart attacks. I've gotten very close to having heart attacks due to this condition twice, believe me, I know. So don't waste time and get checked out.
