There are many risk factors for coronary heart disease. Your risk of coronary heart disease goes up with the number of risk factors you have and how serious they are. Some risk factors—such as high blood pressure and high blood cholesterol—can be changed through heart-healthy lifestyle changes.

Many people who have conduction disorders, such as first-degree AV block, may have no obvious signs or symptoms.
