In the past post, we have acknowledge on how you will get the risk for CVD by knowing the risk factors. Now, let us get to know how the CVD will be diagnosed. When your doctor thinks that you might be developing risk for CVD , those diagnosis will be carried out;
Blood test is one of the common laboratory test to diagnose most of diseases. This test may detect fat, cholestrol, lipid components in blood including LDL, HDL, Triglyceride and certain protein. Protein markers such as Apolipoprotein A1 and B will help in detection of inflammation that may lead to heart disease. During heart attack, muscle cell die and release protein into the booldstream. Cardiac Troponin-T is one of the protein markers to detect recent heart attack other than fibrinogen and PAI-1, high levels of homocycteine, elevated asymmetric dimethylarginine and brain natriuretic peptide (a.k.a. B-type or BNP).
2. Electrocardiogram (ECG)
This test is used to detect any irregularities on the heart beat and the heart rhythm through the electrical impulses.
A moving picture showing the size and shape of heart is used to see how the heart work and any injuries caused by poor blood flow.
4. Stress Testing
This test will need the patient to exercise while the ECG/EKG leads are placed on the body. Exercise use to increase the heart rate. If the patient are not able to exercise due to some constraint, they will receive medicine or pills that may increase their heart rate. Possible signs and symptoms can be observed on the abnormal heart rate or blood pressure, shortness of breath or chest pain and abnormal in the heart rhythm or heart's electrical activity.
5. Chest X-ray
The image of the heart can be observed to see if there are any abnormalities occur on the structure of the heart that may cause CVD.
6. Coronary Angiography / Cardiac Catherterization
This test is use by using dye that will be injected by using a tube (catheter) into the bloodstream threaded to the coronary artery . An image will be shown on the dye that indicate the flow of blood through heart and blood vessels and this is called coronary angiography.
7. Cardiac Magnetic Resonance Imaging (MRI)
Cardiac MRI use radio wave, magnetic and computer to produce a 3D image of the heart. A signal will be produced indicate vary of the tissues will help the diagnosis process.
