Some types of heart disease are quite difficult to differentiate from pulmonary of other cardiovascular disease. One of the most important investigations that re used to diagnose and determine the severity of heart disease is the cardiac stress test. The investigation is available in Princeton and involves the subject being taken through an exercise routine for a specified duration of time with an intention of determining how the rhythm is affected by a reduction in the blood supply.
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 of investigation is the nuclear stress test. In this type, a radioactive material is injected into the body so that it spreads to all the body organs including the heart. A special detector is used to identify the rays that are released by the radioactive substance. This helps to project the image of the heart onto a monitor both at rest and during exercise.
As part of the preparation, there are a number of things that one needs to do. The general advice is that one should fast for at least 4 hours before the investigation. Caffeine is likely to affect the results and should be avoided for at least 12 hours prior to the exercise. Drugs to be avoided include isosorbide mononitrate and isosorbide dinitrate.
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.
There are several situations where this investigation is contraindicated. For instance, it should not be administered to persons who have experienced myocardial infarction in the last 48 hours because of the risk of aggravating the condition. It should also not be done in people who have already been found to have abnormal rhythm but are not yet on treatment.
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.
