New Test to Predict Heart Disease

There are many tests that are associated with ("predict") heart disease. With each test there are important questions that must be answered before the test's true value is known. For example, how well does it perform? (Does it select a high proportion of patients with heart disease while excluding a high proportion of people without heart disease?) Is it a strong predictor or a weak one? Does its predictive value overlap with other tests making its value less? Because of the complexities of answering such questions, physiological testing for existing heart disease (e.g., stress testing) and monitoring the progression of heart disease will continue to have an important role in the detection of heart disease.
