* The secret to detecting the early stages of heart disease may be right at our fingertips. A recent study published in the Journal of the American College of Cardiology found a correlation between patients who have blood vessel dysfunction in their extremities and those with the same affliction in their heart. Researchers say they hope noninvasive procedures, such as finger probes, can act as a screening tool to determine whether a patient should undergo more invasive tests or treatments. The study found that a simple 20-minute finger probe is highly successful in identifying heart problems in patients with chest pain. The next step, according to the researchers, is to extend the study to patients who are not yet showing cardiac symptoms.
