A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
Dipyridamole is thus a pharmacological success diagnostically, but a therapeutic failure because of the coronary steal phenomenon. [ 4 ] Coronary steal is also the mechanism in most drug-based cardiac stress tests ; When a patient is incapable of doing physical activity they are given a vasodilator that produces a "cardiac steal syndrome" as a ...
Regadenoson, sold under the brand name Lexiscan among others, is an A 2A adenosine receptor agonist that is a coronary vasodilator that is commonly used in pharmacologic stress testing. It produces hyperemia quickly and maintains it for a duration that is useful for radionuclide myocardial perfusion imaging . [ 1 ]
A clinically useful form of cardiac protection. Exp Clin Cardiol 2000; 5: 116–121. (Note: Drug or physical loading induced late appearing protection of the heart from severe stress by adaptation to stress) 16. Szekeres L., Pharmacological induction of delayed and prolonged cardiac protection: The role of prostanoids.
The stress test can result in three outcomes: Pass, Partly Pass and Fail, based on the comparison of the quantified risks to acceptable risk exposure levels and a penalty system. Phase 3: Decision, during which the results of the stress test are analyzed according to the goal and objectives defined in Phase 1. Critical events (events that most ...
Mental stress-induced myocardial ischemia (MSIMI) is a medical condition in which acute psychological stress can trigger a transient myocardial ischemia, which is a state of reduced blood flow to the heart muscle, often without the presence of significant coronary artery disease (CAD).
Antidepressant screening tests are employed to assess the effects of genetic, pharmacological, or environmental manipulations. Stress models including learned helplessness, chronic mild stress, and social defeat stress simulate the impact of stressors on depression. Early life stress models, psychostimulant withdrawal models, olfactory ...
Dobutamine is a medication used in the treatment of cardiogenic shock (as a result of inadequate tissue perfusion) and severe heart failure. [2] [3] It may also be used in certain types of cardiac stress tests. [2]
