Heart disease can mimic many other forms of illness a fact that greatly delays the making of a proper diagnosis. A cardiac stress test is one of the most useful investigations of not only diagnosing heart disease but also assessing its severity. The investigation, available in Princeton, is usually performed by either a doctor or a trained technician and specifically determines how much physical exercise one can tolerate before their rhythm is affected by reduced blood flow.
There are a number of different types of this investigation that can be performed. One of the types includes the use of the treadmill. One is connected to a machine known as an electrocardiogram, ECG, which determines the heart rhythm. The doctor will determine how far one can walk before they start experiencing chest pain or the ECG begins to show abnormalities.
Another commonly performed test is the Dobutamine or Adenosine Test. This type is offered as an alternative to persons that cannot participate in supervised physical exercise. Adenosine and dobutamine are pharmacological agents that have the ability to stimulate the heart in the same way as exercise does. A stress echocardiogram uses a heart ultrasound to visualize the image of the heart as it transitions from a resting state to a strained state.
The last type is known as the nuclear stress test. Here, a small amount of a radioactive material is injected into the body and flows to all the organs. The physician uses a special camera to detect the radioactive rays that are released by the substance. The heart is projected onto a monitor as a clear image. The images are obtained both at rest and during physical exercise to detect any reduction in blood supply.
One needs to do a number of things as part of things as part of the preparation for the investigation. You should not eat or drink anything at least four hours prior to the exercise. Caffeine should be avoided for a minimum of 12 hours. Some drugs may interfere with the results. Such include isosorbide dinitrate and isosorbide mononitrate and should also be avoided.
This investigation has several other benefits other than being useful in diagnosis abnormal blood flow patterns in the heart. For persons that a diagnosis of heart disease has already been made, the test is used to determine the effectiveness of drugs such as those that are used for the treatment of angina. It is also used in the assessment of valve function.
The stress test is not for everyone. There are a number of situations in which it is contraindicated. One example is a person who has had a myocardial infarction within 48 hours. Persons who already have abnormal heart rhythm and are not on treatment may exhibit abnormal responses. The abnormalities should be treated first.
Making a diagnosis of a cardiac conditions usually requires a wide range of tests. These tests are needed to firstly, confirm that a heart abnormality exists and secondly, to identify the exact condition. The cardiac (ECG) stress test is among those that are commonly used for screening. Other tests are usually needed to determine the exact diagnosis.
