Is cholesterol a risk factor for heart disease?

Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease. With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries.

Instead, a better strategy for gauging a heart attack is to look at your overall symptoms.

Why do silent heart attacks happen?
