In my previous article I explained the signs and symptoms that you might have which reflects the status of your hypertension of pulmonary origin. They are used for the purpose of primary diagnosis for this disorder.
Now further evaluation of your disease requires confirmatory tests. These will probably be tests conducted for ruling out the probability of related but different disorders. Therefore for this purpose you would have to undergo a series of such tests.
So what are these tests and why should I have them performed on me?
Online pharmacy is here to help you understand the significance of these tests. Although in many cases the disease is diagnosed but provisionally in patients, so it is likely to have these following be performed on you.
These general tests procedures include the following:
• Pulmonary function tests to check your pulmonary status
• Blood tests to rule out the presence of diseases such as AIDS/HIV, autoimmune diseases, and liver disease.
• Electrocardiography (ECG) to check out related abnormality of cardiopulmonary origin
• Arterial blood gas measurements
• X-rays of the chest that might be followed by a high-resolution CT scanning. The scan is performed when there is suspected interstitial lung disease.
• Ventilation-perfusion or V/Q scanning that is to exclude the chronic thromboembolic pulmonary hypertension.
• Lung tissue biopsy is indicated only when you are suspected to have an underlying interstitial lung disease otherwise it is not much regarded in pulmonary hypertension.
• A point to note here is that if a high intrapulmonary blood pressure, there is a risk of bleeding in simplest of lung biopsy.
Which procedure is the most specific other than the above mentioned tests?
For the diagnosis of pulmonary artery hypertension you must know one thing that there are always two associated conditions with this problem. They are namely Pulmonary artery occlusion pressure (PAOP) that should be less than 15 mm Hg (2000 Pa) and pulmonary vascular resistance (PVR) which must be greater than 3 Wood units (240 dyn•s•cm-5 or 2.4 mN•s•cm-5). If these two conditions are found to as mentioned above then you are a pulmonary hypertension patient.
Echocardiography can be used to estimate the pressure of the pulmonary artery but there is a more definite assessment with the Swan-Ganz catheter. This is because the PAOP and PVR cannot be measured directly with echocardiography. Thus the diagnosis of PAH requires a right-sided cardiac catheterization. This procedure uses a Swan-Ganz catheter that can also measure the cardiac output, which is a far more important tool in measuring disease severity than the pulmonary arterial pressure.
As the Normal pulmonary arterial pressure has a mean value of 12-16 mm Hg (1600-2100 Pa) and that too in a person at sea level. But if you have Pulmonary hypertension your mean pulmonary artery pressure will exceeds 25 mm Hg (3300 Pa) at rest or 30 mm Hg (4000 Pa) with exercise.
Often reported on the echocardiogram reports Mean pulmonary artery pressure (mPAP) is generally confused with the systolic pulmonary artery pressure (sPAP). So when you get your echocardiogram report you should be aware of it. A systolic pressure of 40 mm Hg typically implies a mean pressure more than 25 mm Hg that is roughly, mPAP = 0.61•sPAP + 2. So don' forget to check these out in your reports.
What tests are there which indicates the improvement of my disease?
The chances of improving clinically can be checked by the simple walk test known as the "six-minute walk test." If you are to be checked for stability and improvement in your disease this measurement will correlate with better survival. In this test you would have to walk for 6 minutes and the distance you walk will indicate and this assess the relation between distance walked during the six-minute walk test and exercise capacity determined by your maximal cardiopulmonary exercise testing.
Brain natriuretic peptide (BNP), now known as B-type natriuretic peptide or GC-B, is a 32 amino acid polypeptide which secreted by your heart ventricles in response to excessive stretching of heart muscle cells (cardiomyocytes). So it can be used to follow the progress of patients with pulmonary hypertension.
Though this disease is rare and you might not know about it until the symptoms surface out with much force it still treatable and depends on your will power as is the case in all diseases. Watch out for more on pulmonary hypertension at pharmacy online.
