One of the negative prognostic factor is the<unk>  inability to perform<unk>  test. In<unk>  who cannot<unk> , depending on specific<unk> factors like heart rate, blood pressure, the presence or absence of bronchospasm, the presence of left bundle-branch block , and ventricular arrhythmias suitable type of pharmacologic stress test is advised. Pharmacological agents such as dobutamine induces stress by increasing cardiac contractility and heart rate while vasodilators such as dipyridamole or adenosine increase the overall coronary blood flow and produce regional differences in perfusion. The presence of a perfusion defect as observed with dipyridamole-thallium-201 is an independent prognostic factor. Dobutamine induced ventricular wall motion abnormalities as seen on echocardiography is associated with myocardial viability and restenosis.
