5 Things We Now Know About Pulmonary Arterial Hypertension

Pulmonary Arterial Hypertension

A specific kind of pulmonary hypertension is pulmonary arterial hypertension (PAH). It is caused by the narrowing and thickening of the small arteries in your lung. This constriction restricts blood flow through the lungs, increasing pulmonary blood pressure. Your heart has to work harder as a result. With time it becomes less and less capable of adequately pumping blood throughout the body.

Although it is a fatal condition. It is manageable if you receive a timely diagnosis from the best lung doctor in Michigan and nearby places.

Do You Know?

About one in three American adults has high blood pressure, often known as hypertension. You probably know someone who has gone through this. You might even possess it.

On the other hand, pulmonary arterial hypertension is significantly less common yet has a higher mortality risk.

What Is Pulmonary Arterial Hypertension

A type of elevated blood pressure that develops in the lungs is called pulmonary hypertension. Numerous conditions. Such as sleep apnea and the more frequently known chronic obstructive lung disease, or COPD, can cause it. One kind of pulmonary hypertension is known as pulmonary arterial hypertension (PAH). It develops when the walls of the arteries leave the right side of the heart and enter the lungs. In this situation, the lungs will become constricted and narrow. As a result, the lungs’ pressure increases, causing signs and symptoms like exhaustion and shortness of breath.

The appropriate diagnosis and treatment are essential for persons who have PAH. Due to it increasing over time and there is presently no cure. Despite the fact that the real prevalence of the disorder is still unclear. Moreover, it is thought to be between 50 and 100 people per million.

Here is a primer on the facts concerning PAH. Whether you belong to that group or you are just interested in learning more about the frequently fatal ailment.

Following are the 5 major factors you should know about pulmonary arterial hypertension (PAH).


Regular (systemic) hypertension is a condition that increases the risk of heart attack and stroke. Because it results in excessive blood pressure pushing against the walls of the arteries.

When referring to the five different kinds of pulmonary hypertension, PAH is referred to as Group 1.

Although There Is No Recognized Cause For PAH, Physiological Changes Are Essential To Its Growth And Development.

PAH is diagnosed as, the mean, or average, blood pressure is measured, leaving the arteries on the right side of the heart. It will be 25 mmHg or greater. Although the specific cause of the series of events that led to PAH is unknown. The specialists are quite knowledgeable about its development.

These vessels first become constricted, which causes the vessel wall to change. According to professional opinions, when blood vessels’ walls thicken, so do their lumens, which is the area through which the blood flows. As a result, pressure increases. Pressure keeps increasing as the condition increases. However, the right ventricle of the heart is not built to pump blood against such high pressure.

There Are Four Types Of PAH

Professionals claim that most types are regarded as idiopathic. Which means that there is not a clear cause or significant precipitating element.

Only 6% of illnesses are heritable. They are inherited from a parent, perhaps as a result of a mutation in a protein receptor that controls tissue growth. Having this gene does not guarantee that you will develop PAH. However, it does put you at a higher risk.

In some cases, PAH can be drug-induced. The medication most famous for causing PAH is fen-phen (fenfluramine and phentermine). It is a weight loss drug that was popular in the 1960s and 1970s but is no longer on the market.

Last but not least, associative cases take place when PAH co-occurs with a different pre-existing ailment. Such as HIV, congenital heart disease, or scleroderma.

All four types associative, hereditary, idiopathic, and drug-induced are treated similarly. However, depending on which one you have, your prognosis may differ.

For instance, patients who have been linked with PAH already have scleroderma. Furthermore, they are already more affected by renal disease, GI issues, and heart issues. That may shorten your life expectancy overall.

 PAH Affects Women More Than Men

According to the Pulmonary Hypertension Association, women are at least twice as likely as males to have idiopathic and hereditary forms of PAH. In reality, women between the ages of 30 and 60 are the majority of those diagnosed with PAH.

Although the exact reason why women are more vulnerable is unknown. Several theories under examination have to do with the function of estrogen changes (including hormonal ones). These hormonal changes take place during pregnancy and are connected to autoimmune conditions, which are also more common in women.

 PAH Is Difficult To Diagnose

Given the rarity of PAH, a doctor may first order testing for illnesses like asthma and congestive heart failure. This is acceptable when a patient complains of symptoms like tiredness and difficulty breathing.

While that makes sense in some ways, experts say those problems are significantly more frequent than PAH. It also implies that a PAH diagnosis may occasionally be delayed.

Before seeing a pulmonologist or cardiologist who diagnoses PAH, you might first visit a general practitioner. After that an asthma specialist, another specialist, and so on. A correct and definitive diagnosis of PAH often takes one year after the onset of symptoms, according to another statement.

The good news is that the time it takes to diagnose PAH, in the beginning, is shortened. Things are gradually changing as more physicians become familiar with PAH and how to recognize it.

A set of tests may include a chest X-ray, pulmonary function test, and exercise tolerance test. All these tests will be ordered by your doctor (most likely a cardiologist or pulmonologist) once they suspect PAH. You will likely need a right heart catheterization, which evaluates the pressure inside the pulmonary arteries. If the results of these tests reveal that all indications still point to PAH.

Although PAH Has No Known Treatment, There Are Efficient Techniques To Control The Condition

On a physiological level, a number of various biological systems are also referred to as pathways. They are associated with the operation of blood arteries and are thought to contribute to PAH.

The guidelines strongly advise starting a medication combination to target two separate routes as soon as a patient is diagnosed with PAH. According to medical experts, you might receive one medication first, then begin taking a second one within six months. The most recent research indicates that focusing on three pathways simultaneously may improve results.

Although PAH is incurable at the moment, the prognosis is generally substantially better than it was 25 years ago. According to medical professionals, the median survival [from the time of diagnosis] used to be 2.5 years. Professionals stated that the majority of patients live between seven and ten years, and some even reach a 20-year lifespan.


According to Dr. Talib Raza pulmonologist research is currently being done to identify a new pathway and a potent medication. Furthermore, it may be used to target it. Our medical professionals are committed to making it happen.
