Test, physiologic stress definition - medical term
Although there can be a diversity of physiologic stress tests, this refers here to a
physiologic cardiac stress test in which certain medications are administered that stimulate the heart to mimic the physiologic effects of exercise.
One of these medications is dobutamine, which is similar to adrenaline. Dobutamine is carefully administered to gradually increase the heart rate and strength of the contractions of
the heart muscle. Simultaneously, echocardiography or radionucleide imaging is performed. Alternatively, a medicine called adenosine is administered, which simulates the physiology of the coronary artery circulation during exercise. Adenosine is combined with radionucleide
isotope imaging to provide a very accurate test for the detection of significant coronary artery disease (CAD).
Pharmacological stress testing is commonly performed
in patients who are thought to be at high risk for significant CAD and who are scheduled for major non-cardiac surgical procedures. These patients are often unable to perform exercise stress testing due to the underlying condition for which they require surgery. In this setting, pharmacological stress testing is invaluable in assessing the cardiac risk of patients prior to surgery.
