Pulmonary Arterial Hypertension: Causes, Symptoms, Treatment

What is Pulmonary Arterial Hypertension?

Pulmonary Arterial Hypertension refers to high blood pressure in the pulmonary arteries (PAH). The pulmonary arteries are significant blood vessels in the lungs that transport blood from the right heart to the lungs.Unlike other varieties of increased blood pressure, pulmonary arterial hypertension (PAH) is difficult to diagnose because it differs from other types of pulmonary hypertension (PH).In the event that you have PAH, there are drugs available to help control your symptoms, such as maintaining a well-balanced diet and engaging in regular physical exercise.

Pulmonary arterial hypertension is a medical term that means what?

Pulmonary Arterial Hypertension ( PAH ) is defined by the National Organization for Rare Disorders (NORD) as “apparently random” elevated blood pressure in the lungs’ arteries. A person with Pulmonary Arterial Hypertension has substantially stronger blood flow from the heart to the airways than is normal for that individual’s age and health status.


Physicians are baffled as to the exact aetiology of Pulmonary Arterial Hypertension. People with Pulmonary Arterial Hypertension are generally diagnosed between the ages of 30 and 60, and women are more likely than men to be affected.
  • People may be more susceptible to developing PAH during or after pregnancy, according to research on the function of female sex hormones in the disease.
  • PAH can also be hereditary. Hypertension is passed down in families in 15–20% of instances.
  • BMPR2 germline mutations may contribute to PAH, however, this may not compensate for all cases. Only 20% of those with the PAH gene mutation will get the disease, suggesting that ecological or lifestyle variables work in concert with it to set it off. Even without the genetic mutation, some families have a history of PAH, indicating that numerous genes are involved.
  • As a result of WHO’s investigation into the causes of PHT, notably PAH, five distinct risk categories have been identified. Those who have PAH are classified as having PHT that has no known cause or that is caused by genetics, drug usage, or a medical condition.
PAH can be caused by a number of different health issues.
  • a disorder of the connective tissues
  • heart disease caused by HIV from birth
  • a problem with the liver
  • Sickle cell anaemia is a serious health problem.


Totally inadequate air in the blood is usually the cause of Pulmonary Arterial Hypertension symptoms. After exertion, significant shortness of breath may be the first complaint that a person notices.Other signs and symptoms to look out for are:
  • fatigue\weakness
  • dizziness
  • chest ache when attempting to get up
  • an uncontrollable cough, which can cause blood clots in the face, ankles, feet, and stomach.
  • Cyanosis, or colouring of the lips, epidermis, face, and other mucous membranes, is a symptom of severe PAH.
Depending on the hue of one’s skin, cyanosis can manifest itself in many ways. Skin and lips might seem blue on white people because of their ethnicity. Discolouration can be more noticeable in the eyes and complexion of Black individuals, who are more likely to appear grey or white.Unfortunately, because the manifestations of Pulmonary Arterial Hypertension are so identical to those of other cardiac disorders, the illness cannot be diagnosed just by looking at the patient’s medical history.


  • Right cardiac catheterization, a technique that measures blood flow, is the most accurate approach to diagnose PAH. In this surgery, a clinician inserts an ultra-thin catheter into the afferent arteriole via another blood channel, such as a vein or the neck. By doing this, they can examine how far and how quickly blood is moving through their veins. Doctors may administer sedatives to patients who are having surgery while they are awake.
  • Other tests may be ordered by the doctor to rule out other possible reasons or to see whether another condition is contributing to the development of PAH. Included in these evaluations are those that look for things like:
  • HIV and autoimmune diseases are both detected by blood testing. the noninvasive ECG, which displays electrical irregularities in the heart, and the echocardiogram, which utilises sound waves to image the heart and see blood flow patterns.
  • Breathing rate and breathing tests are used as part of a functional evaluation, which is also known as the 6-minute walk test. A doctor should be informed about all your symptoms, including any experience of PAH or other heart-related issues in your family.

Options for therapy

Several Pulmonary Arterial Hypertension medicines have been given the green light by the FDA.These are a few examples:
  • These medicines, known as prostaglandins, may be useful for those who haven’t responded to conventional forms of treatment.
  • These medicines, known as endothelin receptor antagonists, can aid with shortness of breath.
  • Phosphodiesterase type 5 ligands: When someone walks or engages in other physical activity, these medications may help lower their blood pressure. These Medicines are Sildenafil Vidalista 20.
  • Vasodilators: These medications assist expand the capillaries, which in turn helps lower blood pressure and alleviate the associated symptoms.
  • Riociguat was licenced by the FDA in 2013 for the management of Pulmonary Arterial Hypertension. Another FDA-approved medicine, selexipag (Uptravi), may be used by doctors to help relax blood vessels and lower arterial blood pressure. This drug is also FDA-approved.
  • Sildenafil citrate, the active ingredient in each Cenforce 100 mg tablet, is also used to treat a disease known as pulmonary arterial hypertension.The doctor will prescribe a precise timetable for taking your medications, but in general, Sildenafil citrate pills are taken 2-3 times per day if used to treat pulmonary arterial hypertension. Your doctor may provide you with further information on the use of Fildena 100  mg tablet for the treatment of pulmonary arterial hypertension.
  • Supplemental treatment, such as oxygen therapy, may be required for certain patients. An organ transplant may indeed be necessary if the patient’s condition is critical. The patient’s medical staff may suggest a cardiovascular, single-lung, or dual-lung transplant.
  • Adjustments to diet and exercise: Adopting a healthier lifestyle might help alleviate symptoms for some people.
  • Some examples are as follows:
  • tossing out the smokes if you’re an active smoker;
  • eating a heart-healthy diet of fruits, veggies, and whole grains;
  • achieving a healthy weight and staying there
  • maintaining a healthy lifestyle
  • Lifting large weights or engaging in other strenuous activities should be avoided if possible, even if it is good for your health.
PAH symptoms, such as exhaustion, chest tightness after activity, and chest discomfort, should be reported to a doctor. Because the properties are similar to those of other cardiac disorders, a proper diagnosis is critical.
