Angina: Its Causes, Types, and Symptoms

What Is Angina?

Have you ever had a tight, squeezing chest pain when you're walking quickly, climbing stairs, or under stress? That could be angina, a sign that your heart isn't getting an adequate flow of oxygen-rich blood. Angina is not an illness in itself. It's a warning sign from your body that something is amiss with your heart, usually due to coronary artery disease (CAD). In CAD, the blood vessels supplying your heart become narrowed due to the accumulation of fatty plaque. This narrowing restricts blood supply, forcing your heart to work harder than usual.

What Does Angina Feel Like?

Angina is described differently by different people. It may feel like pressure or tightness in the chest for some. For others, it's a burning or squeezing sensation. At times, pain radiates to the arms, neck, jaw, back, or stomach.

1. You may also experience

• Shortness of breath.

• Dizziness or weakness.

• Nausea.

• Sweating or anxiety.

These symptoms typically appear during physical activity or emotional stress and usually subside with rest.

2. Types of angina

Angina presents in various forms with a characteristic pattern.

• Stable angina: It is the most common type. It is also known as classical angina. The pain usually comes when you are active or under stress and goes away when you rest or take your medication.

• Unstable angina: This is more severe. It occurs suddenly, even at rest, and will linger for a longer period. It's an indication that a heart attack is likely on the horizon., Unstable angina is dangerous and requires medical attention.

• Variant angina (Prinzmetal's angina): This is caused by the sudden constriction of a heart artery and the resultant cutting off of blood flow. This typically comes on at rest and is very painful. Variant angina is also known as Prinzmetal or vasospastic angina.

• Microvascular angina: In this condition, the issue is not with the large blood vessels of the heart, but rather with the smaller blood vessels. It's also more common in women and can cause pain in the chest even if the main arteries are fine.

What Causes Angina?

The most common cause of angina is coronary heart disease. When plaque builds up in your arteries, they narrow, and the blood supply is reduced. When your heart must work harder, for example, when you exercise or get upset, it needs more oxygen. If it doesn't get enough, that's when it hurts.

Risk Factors

Some factors raise your risk of getting angina:

• Smoking.

• High blood pressure.

• High cholesterol.

• Diabetes.

• Being obese.

• Not exercising regularly.

• Family history of heart disease.

• Long-term stress.

• Getting older.

The good news is that most of these risk factors can be managed by lifestyle changes.

What Are the Signs and Symptoms of Angina?

The classic symptom is chest discomfort or pain, but it doesn't feel the same for everyone. The pain may feel like:

• Pressure or tightness in your chest.

• A squeezing sensation that spreads to your arm, neck, or jaw.

• A heavy sensation in your chest when exerting yourself.

Symptoms of female angina can differ occasionally. Women are most likely to be feeling short of breath, exhausted, or queasy, or having jaw or back pain rather than chest pain. If at any time you have new, more severe, or worsening chest pain, do not dismiss it; get immediate medical care.

How Is Angina Diagnosed?

If your physician is suspicious that you have angina, they will start with a series of straightforward tests:

• Physical examination and medical history: To find out about your symptoms and risk factors.

• Blood tests: To check sugar and cholesterol levels.

• Electrocardiogram (ECG): To record your heart's electrical signals.

• Stress test: To see how your heart responds when you exercise.

• Echocardiogram: An ultrasound that tells you how your heart is doing.

• Coronary angiography: An X-ray with special dye to show up any blockages.

These tests will help your doctor determine the cause and choose the most effective treatment for you.

How Is Angina Treated?

Angina treatments have one agenda in mind: ease pain, prevent heart attacks, and allow you to lead a normal life.

1. Medications

Your doctor can prescribe angina medication to help control angina symptoms.

• Nitrates (like nitroglycerin): To quickly calm chest pain.

• Beta-blockers: To slow down your heart rate and lower blood pressure.

• Calcium channel blockers: To relax blood vessels and improve blood flow.

• Aspirin: To stop blood clots from forming.

• Statins: To lower cholesterol.

• Ranolazine: Chronic angina, along with other angina medications.

2. Surgical Procedures

If pills alone can’t help with angina, you might need:

• Angioplasty and stent placement: Where doctors widen the blocked artery with a small balloon and keep it open with a stent.

• Coronary bypass surgery: Doctors create a new pathway for blood to flow to the heart.

How Is Angina Prevented?

The best way to prevent angina is to protect your heart by changing your lifestyle. Give these healthy habits a try:

• Stop smoking (it's the most significant risk factor).

• Eat more fruits, vegetables, and whole grains.

• Exercise regularly; even a 30-minute walk is beneficial.

• Maintain a healthy weight.

• Control high blood pressure, cholesterol, and diabetes.

• Learning stress management, meditation, or deep breathing can help.

Other medical conditions that may result in chest pain. Not all chest pain is angina. So, visit a doctor immediately if you’re unsure. Sometimes, it’s caused by:

• Muscle strain.

• Acid reflux or heartburn.

• Lung infections (like pneumonia).

• Anxiety or panic attacks.

• Inflammation of chest muscles (costochondritis).

Lifestyle Changes to Manage Angina

If you’ve been diagnosed with angina, daily choices matter a lot. Here’s what can help:

• Take your medications exactly as prescribed.

• Keep a Nitroglycerin tablet nearby if your doctor recommends it.

• Avoid abrupt heavy physical exertion or emotional stress.

• Have lighter and healthier meals.

• Sleep and rest well.

• Have regular heart checkups.

Discuss safe exercise levels with your doctor.

Conclusion

Angina is your heart saying, "I need more oxygen!" It is a result of blocked or narrowed arteries, but with proper treatment, it can be fixed. Stable angina can be managed with medicines and lifestyle changes. However, unstable angina is more serious and needs to be treated immediately. Understanding the various types of angina, their causes, and effective treatment options empowers you to take care of your heart. Remember: never dismiss chest pain.
