Pulmonary Hypertension 

PH which stands for Pulmonary Hypertension is a critical disease of hypertension in the pulmonary arteries. The arteries deliver low Oxygenated blood to the lungs from the right side of the heart. Pulmonary hypertension reduces the amount of blood that gets to the heart and the lungs, and this is the reason it is a serious disease. If left unchecked, PH may cause progressive decline of the heart and result in the development of additional problems that encompass the entire body. If diagnosed early enough, the condition can be treated otherwise it may lead to lethal conditions. 

What is Pulmonary Hypertension? 

A form of high blood pressure called pulmonary high blood pressure damages the arteries in the lungs as well as the right side of the heart. The pressure inside the tiny arteries in the lungs rises when they narrow or get clogged, making it more difficult for blood to pass through them. If this pressure is not well controlled, it may eventually force the right ventricle of the heart to beat harder, which might result in cardiac failure. Severe pulmonary hypertension needs continuous care and treatment, as contrast to normal pulmonary hypertension, which may be a transient reaction to stress or other circumstances. 

Types of Pulmonary Hypertension

Pulmonary hypertension is categorized into five types based on its causes: 

• Pulmonary Arterial Hypertension (PAH): This is the type of narrowing or blockage of pulmonary arteries due to varied factors including those genetically or other unknown causes 
• Pulmonary Hypertension due to Left Heart Disease: This type results from the effects of left heart diseases like mitral valve disease, or the long-term effects of high blood pressure on the pulmonary arteries. 
• Pulmonary Hypertension due to Lung Diseases: Long-standing conditions like COPD or interstitial lung disease may cause this type. 
• Chronic Thromboembolic Pulmonary Hypertension (CTEPH): This is a rare type of pulmonary hypertension caused by blood clots in the lungs that don't resolve and hence keep obstructing normal perfusion continuously. 
• Pulmonary Hypertension due to Multifactorial Mechanisms: This type involves multiple factors, including systemic disorders, metabolic diseases, or other conditions that simultaneously affect the lungs and heart. 

Symptoms of Pulmonary Hypertension 

The very first Pulmonary hypertension symptom is shortness of breath, which you would feel in the course of daily activities, such as climbing stairs or shopping for groceries. You could also experience a shortage of breath during exercise. At the beginning of pulmonary hypertension, you do not show any symptoms. Later, you will find that such symptoms exist and that they could be mild. However, PH symptoms worsen over time, making daily usual activities quite difficult to conduct. 

Breathlessness will become more frequent as your PH worsens, even if you are not moving. Additional signs and symptoms consist of: 

• Shortness of breath, especially during physical activity 
• Fatigue and weakness 
• Chest pain or pressure 
• Swelling in the ankles, legs, and eventually the abdomen 
• A bluish color to the lips and skin (cyanosis) 
• Rapid heartbeat or palpitations 
• Dizziness or fainting spells 
• Having less appetite than normal
• Pain in your upper right abdomen

Pulmonary Hypertension Causes

Pulmonary hypertension can have various causes, depending on its type:

• Genetic mutations 
• Conditions like heart valve disease or long-term high blood pressure in the left side of the heart
• Chronic obstructive pulmonary disease (COPD), interstitial lung disease, or sleep apnea
• Blood clots in the lungs 
• Autoimmune diseases, liver disease, and certain medications or drug use

Diagnosis

First, you will have a physical test to check for the common symptoms of pulmonary hypertension, as well as other heart or lung problems. Other tests may be done after your physical exam to see if you have a PH. These tests include: 

• Blood Tests: These can diagnose any underlying disease that may be causing PH. 
• Echocardiogram: An echocardiogram utilizes sound waves to create images and video of how the heart is functioning and how the structure of the heart and pulmonary arteries is. 
• Chest X-ray: It shows if your right ventricle or pulmonary arteries are larger than they should be. 
• Chest CT scan: Looks for lung diseases that might be aggravating or causing your pulmonary hypertension, such as blood clots. 
• Pulmonary Function Tests: Examines how well the lungs are working. 
• Right Heart Catheterization: This test measures pressure in your pulmonary arteries and has the capacity to determine blood your heart can pump per minute. 

Pulmonary Hypertension treatment 

Your underlying medical problems and the kind of PH you have will determine how your pulmonary hypertension is treated. Your medical team will customize their treatment to meet your unique requirements. Pulmonary arterial hypertension (PAH) is treated with the following: 

• Medications: These may include vasodilators, anticoagulants, diuretics, and oxygen therapy. 
• Surgery: Surgery could be suggested if medication is ineffective in managing the symptoms of pulmonary hypertension. The following operations and surgeries can be used to treat pulmonary hypertension:
  • Atrial septostomy 
  • Lung or heart-lung transplant 
• Lifestyle changes: Eating a healthy diet, exercising regularly, and avoiding high altitudes. 
• Pulmonary Rehabilitation: A program of exercise, education, and support to help patients manage their condition. 

Risk Factors of Pulmonary Hypertension 

Most people with pulmonary hypertension are diagnosed between ages 30 to 60. Getting older can increase your risk of developing Group 1 pulmonary hypertension, called pulmonary arterial hypertension. PAH from an unknown cause is more common in younger adults. 

Other things that can increase your risk for pulmonary hypertension include: 

• Family history 
• Obesity 
• Congenital heart defect. 
• Other health conditions such as heart disease, lung disease, and autoimmune 
• disorders. 
• Medications and substance use 
• Asbestos exposure. 
• Living at a high altitude. 

Complications of Pulmonary Hypertension

If left untreated, pulmonary hypertension can lead to severe complications. The side effects of pulmonary hypertension are: 

• Right-sided heart failure 
• Irregular heartbeats 
• Increased risk of Blood clots 
• Bleeding in the lungs 
• Pregnancy complications 

When to See a Doctor

In case one has the signs of pulmonary hypertension, mainly shortness of breath, chest pain, or swelling in legs and ankles, it is important to see a doctor. Early diagnosis and treatment can prevent disease progression and improve the quality of life. 

Conclusion

Pulmonary hypertension is a serious condition that should be diagnosed as early as possible and treated accordingly. By having some knowledge on the symptoms, causes, and the various categories of pulmonary hypertension, those affected may be able to get the appropriate help early enough. Proper treatment using drugs, exercise, and occasionally surgical intervention will help in managing the disease to increase the lifespan of the patient, and improve their overall wellbeing. 

FAQs

Q1. How does pulmonary hypertension affect my body?

Ans. Pulmonary hypertension results in high pressure in the pulmonary arteries and an increased stress on the heart's right ventricle. This may result in difficulties in breathing, frequent tiredness, chest pain, heart failure, and other serious outcomes. 

Q2. Can pulmonary hypertension be cured? 

Ans. There is no known cure for pulmonary hypertension; however, all forms of pulmonary hypertension are manageable with medications, lifestyle changes, and at times, surgery. Pulmonary hypertension therapy begins from the time when the illness is diagnosed and continued supportive care can alleviate symptoms and prognosis. 

Q3. What is the main cause of pulmonary hypertension? 

Ans. The common, yet variable, causes of pulmonary hypertension include left heart disease, chronic lung diseases, blood clots in lungs, and genetic factors. All these conditions increase pressure in pulmonary arteries. 

Q4. Can pulmonary hypertension reverse? 

Ans. Pulmonary hypertension cannot be reversed, but early diagnosis and proper treatment do exist that alleviate symptoms and slow progression. In some cases, targeting the causative factor can profoundly improve the condition. 

Q5. What are the stages of pulmonary hypertension? 

Ans. The stages of Pulmonary Hypertension are: 

• Class I: No symptoms during ordinary activity. 
• Class II: Mild symptoms during normal activity. 
• Class III: Noticeable limitation of activity due to symptoms. 
• Class IV: Even while you're at rest, you get symptoms. Whenever you attempt to perform any regular work, the symptoms worsen.
