High cholesterol, also known as hypercholesterolemia, means there is an excess of lipids or fats in the blood. Your liver makes cholesterol to help digest foods and make hormones. You also consume cholesterol in certain foods, but your liver makes all that your body needs to function properly, making the cholesterol you eat excess.
Too much cholesterol can create blockages in the arteries. When it is more difficult for blood to flow through the body, the risk of stroke or heart attack increases. The plaque buildup itself can also be irritated, which will cause a clot to form around it.
High cholesterol does not normally show symptoms until emergency complications have presented themselves. A blood test will let you and your physician know what your cholesterol levels are.

Heart attack symptoms can happen on and off or continuously over the course of a few minutes or a few hours. Chances are, if you have been experiencing chest pain for several days or weeks, it is not related to a heart attack.
If you see somebody having a heart attack, call 911 immediately. If they are conscious, have them chew and swallow an aspirin, which helps prevent blood clots. If they lose consciousness, administer CPR or follow the instructions on an automated external defibrillator (AED) if one is immediately available.
