Overview: A stress test is a diagnostic test used to see how the heart functions while exercising.
A stress test (cardiac stress or exercise stress test) measures how the heart performs while working. It is used mainly to find possible blockages in blood flow to the heart muscle. By itself a stress test is not a primary tool for diagnosing HCM, but it can provide useful information about how well the heart functions under exercise.This means that it is aimed at identifying risk of heart attacks. It can also find abnormal rhythms that occur during exercise. Like anyone else, HCM patients can also develop arterial blockages, although HCM does not appear to make this any more or less likely.
