Pulmonary arterial hypertension is different from regular hypertension such that this particular condition is quite severe and life-threatening in nature. Getting a diagnosis is quite tricky in the initial stages because the symptoms don’t really manifest themselves in the beginning phase. In case one is experiencing any form of shortness of breath, then consulting a doctor is a good first step to getting the diagnosis cleared. Some of the basic questions that a medical practitioner may ask in the initial stages are as follows:

• Do you have the habit of smoking?
• Is there any family history of lung or heart diseases?
• Do you remember when your symptoms started?
• Is there any factor that is aggravating or easing your symptoms in particular?
• Do you experience the symptoms continuously or do they appear in some instances?

Based on how one answers these questions and based on any red flags that the doctor finds, there will be a round of diagnostic tests that will be needed to confirm pulmonary arterial hypertension.

Some of these common diagnostic tests for pulmonary arterial hypertension include the following:

1. Echocardiogram
The blood pressure in the pulmonary arteries is checked by taking an ultrasound picture of the heart by recording its beating.

2. CT scan
This will enable the doctor to check for any pulmonary arteries that are enlarged. This will also help to spot any specific problems in the lungs which may contribute to shortness of breath.

3. X-ray of the chest
Also known as VQ (ventilation-perfusion) scan, this test will be helpful to identify any blood clots that are blocking the pulmonary arteries and causing the pressure buildup in the lungs.

4. Electrocardiogram
Often referred to as EKG or ECG, this test studies the functioning of the heart to detect any strain that is causing the heart to function below its normal rate. These strains are a warning sign of pulmonary arterial hypertension.

5. Chest X-ray
Taking an X-ray can show if there is an artery or part of the heart that looks enlarged. This is an effective way to detect any lung- or heart-related conditions that are taking a toll on the body.

6. Exercise testing
This is a diagnostic test wherein the individual is given an activity on either a treadmill or a stationary bike and is monitored for any form of change that is occurring in the heart function, oxygen levels, and lung pressure. The stats are studied in real-time through mapping them on a monitor as the individual performs the activity.

In addition, a doctor may also prescribe blood tests to check for any autoimmune conditions, HIV, and the like. In the event that the tests show a possibility for pulmonary arterial hypertension, then the next step would be to get a right heart catheterization to confirm the diagnosis. This is a process by which the arteries are analyzed through a series of tests by running a catheter along the jugular vein. This is a safe procedure and is performed by specialists.
