What are the consequences of ignoring coronary artery disease?

Heart attack & death: Eventual heart attack and a shortened life expectancy.

CAD: The number one cause of death in men and women in the U.S.

Angina, CHF & Death : Atherosclerosis, known to start ~age 7 on average, most commonly becomes obvious by reducing/stopping blood supply to portions of the heart muscle; heart attacks (most asymptomatic until large) resulting in congestive heart failure, angina and/or premature death. Stress testing, all forms, completely miss the problem until after the disease is quite advanced & after most smaller heart attacks.
