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.

I am unable to take a stress test while on the treadmill since I have lung and asthma problems. What reactions should I expect from the chemical stress tests?

Depends on lung issu: There are two main types of chemical stress tests: Adenosine and persantine. Adenosine can/and does induce asthma attacks in many asthmatics so make sure the cardiologist knows about your asthma. It can be reversed but they don't like affecting the lungs when posible. Generally what they do is make your heart beat faster and pump harder. So you feel a little jumpy but rarely and specific pain. ...Read more
