Stress (Definition)

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more

What is the definition or description of: myocardial perfusion scan with exercise?

What is the definition or description of: myocardial perfusion scan with exercise?

Cardiac Exam: Myocardial perfusion imaging looks at blood flow to the left ventricle. This is primarily accomplished using nuclear techniques such as pet or spect using radiotracers such as tl-201, tc-99m, or n-13 ammonia. When it is done with exercise, the myocardial perfusion scan shows blood flow during exercise, and usually compares that to perfusion at rest in order to evaluate for inducible ischemia. ...Read more

What is the function of a myocardial perfusion scan?

Blood flow to heart: It shows blood flow to the heart. It can show old scar of a heart attack or heart muscle that is not getting enough blood , which could mean a future heart attack. ...Read more

What are nursing interventions after a myocardial perfusion scan?

What are nursing interventions after a myocardial perfusion scan?

Minimal: 1. Encourage good hydration to encourage washout of the tracer from the kidneys. Be careful against over-hydration in cardiac patients. 2. Rest - usually the patient will have undergone an exercise or pharmacologic stress test, and will be tired. 3. As in any cardiac patient, close monitoring is recommended. ...Read more

What are the risks in having a myocardial perfusion scan?

What are the risks in having a myocardial perfusion scan?

Stress associated : A myocardial perfusion scan is performed in two steps. One injection of a radiotracer at rest and another at stress ( either treadmill or pharmacological stress test with adenosine, regadenoson, dobutamine, dipyridamole). Only few skin reactions have been reported with the radiotracer injection. Risks are more associated with the stress used for the test such has angina, headache, nausea... ...Read more

What is the purpose of a myocardial perfusion scan?

Nuclear stress test: This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine. ...Read more
