Tests to confirm Heart Disease
There are various tests available for the confirmation of coronary heart disease:
1. Physical checkup
Before any other tests are ordered, a complete physical examination of the patient is performed that involves measuring blood pressure and pulse rate. A fresh lipid profile as well as blood sugar are also ordered.
2. ECG (Electrocardiogram)
It is one of the safest tests available. The cardiologists use it most widely. Changes in the ECG are confirmatory of heart disease.
3. TMT (Treadmill Test)
It is done only when the electrocardiogram does not provide any conclusive evidence of Coronary Artery Disease or gives equivocal findings. This is one of the highly reliable non-invasive tests for the confirmation of Coronary Artery Disease.
4. ECHO Cardiogram
It is usually done to find out the pumping power of the heart. It also gives good information about the walls of the heart.
In this test a long wire is used to fill up the blocked tubes of the heart with a radio opaque dye, and thereafter, approximate percentages of the blockages are reported. This is a test which carries a definite risk in itself, in spite of being costly and imprecise. Only those who need to go in for an angioplasty or bypass surgery should go ahead with this test.
6. C.T. Angiography
This is a recent development in the field of diagnostic cardiology which is going to revolutionize the way in which coronary artery blockages are viewed. In this procedure the blockage can be viewed by taking help of the conventional CT scan procedure. Advanced CT scanners have now been developed which can specifically define these blockages. The most important feature of this process is that this form of angioplasty is non invasive unlike the conventional angioplasty which is invasive. The process does not require any admission in hospital and can be performed very quickly as an outdoor process.
