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 would an echo stress test show....That a regular echo test doesn't?

What would an echo stress test show....That a regular echo test doesn't?

Change w/exercise : When excercised, or 'stressed', the heart needs more oxegen to function properly than at rest. If it's not getting that increase, the muscle will start to move in abnormal ways, which will show up on the echo. At rest, because it needs less oxegen, it may be getting enough, so it will look normal then. ...Read more

Dad did well on a stress test. But how are vulnerable plaques checked for? I heard these dont show up on stress test. And i want to make sure no risk

No such thing: It's hard to hear, but the truth: there is never a way to say there is "no risk". If you are worried about heart disease, then focus on prevention to reduce the risk. Heart disease is preventable with a healthy diet and not smoking. Every day is a chance to make healthier choices. Avoid red and processed meats. Limit cheese and dairy products. Get regular aerobic exercise. Don't smoke. ...Read more

ECG stress test: In general to cause ecg abnormalities on an exercise stress test requires roughly a 70% obstruction of at least one coronary artery. There are exceptions to this however. A normal stress ecg can still have coronary artery disease of a significant amount but it usually isn't enough to cause a clinical event in a couple of years time from the test. Your cardiologist is doubtless correct. ...Read more
