Obstructive Sleep Apnea and Pulmonary Hypertension

It is a scientific fact that a few common predisposing factors are shared by Obstructive sleep apnea (OSA) and pulmonary hypertension (PH). However, it is also necessary to know that there exists between these medical conditions a casual bidirectional relationship. A recent study found that lowering the blood pressure to treat PH increases the possibility of relieving symptoms of OSA by improving upper airway tone. It targets hormone pathways (renin-angiotensin system and aldosterone) that may trigger the worsening of OSA. Thus, we write this article to help you know more about the bidirectional relationship that is shared between Obstructive sleep apnea and pulmonary hypertension.

Medicines to Treat Hypertension

What are the Pulmonary Hypertension Symptoms?

What are the pulmonary hypertension symptoms?

Pulmonary hypertension, or PH, is a medical condition in which very high blood pressure harms arteries within the lungs as well as on the right side of the heart. Now, some signs indicate its presence in the human body in PH. It is essential, especially for all of you who suffer from this type of hypertension, to know about them so that you can take appropriate action as soon as possible.

Therefore, here is a list of a few significant pulmonary hypertension symptoms. They are:

  1. Dizziness or fainting spells
  2. Pressure or pain in the chest
  3. Dyspnea or shortness of breath
  4. Oedema (swelling) in the ankles and the legs
  5. Fatigue
  6. Rapid heartbeats (palpitations)

Causes of Pulmonary Hypertension:

When healthcare professionals speak about the causes of pulmonary hypertension, you must understand that this medical condition is divided into five groups. Each of the PH types can occur anytime and season within an individual due to different reasons. They are as follows:

Group 1: Pulmonary Arterial Hypertension or PAH:

The causes are as follows:

  1. Changes in genes that have transferred from one generation to another
  2. Congenital heart disease
  3. Abuse of certain illegal substances or drugs
  4. Presence of other severe medical disorders such as cirrhosis of level and HIV infection
  5. Unknown cause

Group 2: Pulmonary Arterial Hypertension Effect on the Left Side of the Heart:

The causes include:

  1. Failure of the lower left heart chamber
  2. Malfunctioning of the mitral or aortic valve

Group 3: Pulmonary Arterial Hypertension Due to Lung Disorder:

Causes are inclusive of:

  1. Sleep apnea
  2. Chronic obstructive pulmonary disease, or COPD
  3. Pulmonary fibrosis
  4. Exposure to high altitude

Group 4: Pulmonary Arterial Hypertension Triggered By Chronic Blood Clots:

A couple of causes include:

  1. Other clotting disorders
  2. Chronic blood clots in the lungs

Group 5: Pulmonary Arterial Hypertension Due to Other Health Conditions

  1. Kidney disease
  2. Metabolic disorders such as glycogen storage disease
  3. Inflammatory diseases like vasculitis and sarcoidosis
  4. Blood disorders, including polycythemia vera
  5. Tumours that press against pulmonary arteries

What is the Pulmonary Hypertension Treatment?

If you want to experience relief from pulmonary hypertension symptoms, there are a few pulmonary hypertension treatment methods that you can use. They are as follows:

X-Ray of the chest: An X-ray is an image that helps give your doctor the complete picture of your chest, including the heart and chest of the organ.

Therefore, you can use it to check for every type of lung function.

Blood tests:

It is a test that helps determine the real cause of pulmonary hypertension.

  • Echocardiogram:

An echocardiogram is a test that involves the use of sound waves that help in creating moving images of the beating heart. It helps in the comprehensive diagnosis of pulmonary hypertension.

  • What is a bidirectional relationship that is shared between obstructive sleep apnea and pulmonary hypertension?

Have you ever wondered what is the bidirectional relationship shared between Obstructive Sleep Apnea and Pulmonary Hypertension? Here is presenting to you the explanation for it:

OSA triggers individual pulmonary hypertension via the activation of the hypoxia pathway. Hence, this eventually leads to a rise in left atrial pressure, leading to pulmonary venous hypertension.
