Diagnosing coronary artery disease

People who follow a healthy lifestyle can still have the early stages of coronary artery disease (CAD), the most common type of heart disease. There are many ways people can find out if they have CAD. This includes paying attention to whether exercise causes discomfort, doing a 10-year heart risk assessment, and seeing their doctor for diagnostic testing, such as a coronary artery calcium scan, a resting electrocardiogram, a walking stress test, or an echocardiogram. A doctor uses this information to determine the best treatment path.

Certain drugs, supplements, or foods can interact with common heart medications. Known as drug-drug or drug-nutrient interactions, these can occur at any point of the drug's "life cycle:" absorption, metabolism, or excretion.

For example, grapefruit juice can elevate blood levels of certain statins and potentially increase the risk of side effects.
