People with very high calcium scores (over 1,000) have a risk of heart attack or stroke similar to those who have already had a heart attack. They should take cholesterol-lowering drugs to bring down LDL levels and possibly undergo additional testing.

A healthy diet is a proven and powerful way to lower your risk of heart disease. Since dinner is often the main meal of the day, it's a good time to feature foods that support cardiovascular health.
