What You Need to Know About Angina Pectoris

Angina pectoris is a condition that is characterized by chest pain or discomfort. It occurs when the heart muscle is not receiving enough oxygen-rich blood.

If you are experiencing chest pain, it is important to know that you might be suffering from angina pectoris. This condition can cause a great deal of discomfort and should not be ignored. In this blog post, we will discuss the symptoms of angina pectoris as well as the treatment options available. We will also provide some tips on how to manage this condition.

What is angina pectoris?

Angina pectoris is a condition that is characterized by chest pain or discomfort. This pain can vary in intensity and may feel like a squeezing sensation. It typically occurs when the heart muscle is not receiving enough oxygen-rich blood. Angina is not a heart attack, but it indicates an increased risk of having a heart attack.

Angina pectoris is a common symptom of coronary artery disease. It is the most prevalent heart disease in the world. When plaque builds up in the coronary arteries that supply blood to the heart, restricting blood flow, CAD occurs.

Types of angina pectoris

The types of angina:

Stable angina

Stable angina is the most common type. It usually occurs during physical activity or when you are under emotional stress. The pain typically goes away within a few minutes with rest or by taking nitroglycerin.

Unstable angina

Unstable angina is more serious. It can happen without physical activity or emotional stress and often occurs at night. The pain from unstable angina can last for more than 15 minutes and is not relieved by rest or nitroglycerin.

Variant angina

A third, less common type of angina is variant angina. This type of chest pain is caused by spasms in the coronary arteries. These spasms can happen at rest and often occur in the early morning hours.

Refractory angina

Despite a variety of treatments and modifications to one’s lifestyle, angina episodes are common.

Microvascular angina

Microvascular angina is a form of angina that affects tiny arteries rather than big coronary vessels. It produces pressure in the chest that has no connection with a blocked coronary artery. The discomfort originates from poor blood vessel function in the arms, legs, and heart. It is more common in women than men.

What causes angina pectoris?

Angina is an illness characterized by reduced blood flow to the heart muscle. Blood delivers oxygen to the heart muscle, which it requires to survive. When the heart muscle doesn’t receive enough oxygen, ischemia occurs as a result.

Coronary artery disease is the most common reason for a decrease in heart muscle blood flow (CAD). Plaques are fatty deposits that may narrow down the heart’s (coronary) arteries.

Several factors can contribute to the development of angina. These include:

  • Atherosclerosis: This is the buildup of plaque in the arteries. The heart (coronary) arteries can become narrowed.
  • Coronary artery spasm: This is a tightening of the muscles in the walls of the coronary arteries. This can reduce or block blood flow to the heart muscle.
  • Heart valve disease: This is a condition in which one or more of the valves that control blood flow through the heart don’t work properly.
  • Heart failure: This is a condition in which the heart can’t pump enough blood to meet the body’s needs.

Risk factors of angina

There are several risk factors for angina, including:

  • Smoking and tobacco use
  • Advanced age
  • High blood pressure
  • High cholesterol
  • Family history of heart disease
  • Obesity
  • Sedentary lifestyle
  • Medications: Prinzmetal’s angina can be caused by medications that tighten blood vessels, such as some migraine medicines.
  • Anemia: This is a condition in which there are not enough red blood cells to carry oxygen to the body’s tissues.
  • Sleep apnea: This is a condition in which a person stops breathing for short periods during sleep.
  • Diabetes: This is a condition in which the body can’t properly use or store sugar.

Angina pectoris may be triggered by physical activity, emotional stress, cold weather, or heavy meals.

What are the symptoms of angina pectoris?

The main symptom is chest pain. The chest pain or discomfort may feel like a burning sensation, a feeling of fullness, pressure, or squeezing.

In addition to chest pain, other common symptoms of angina pectoris include shortness of breath, fatigue, sweating, dizziness, and nausea. The pain may also radiate to the shoulders, arms, neck, or jaw.

How is angina pectoris diagnosed?

Angina pectoris is usually diagnosed based on a review of symptoms and a physical examination. A doctor may also order tests, such as:

  • Blood tests: These tests can check for conditions that may contribute to angina, such as anemia or diabetes.
  • EKG (electrocardiogram): This test records the electrical activity of the heart and can detect heart abnormalities.
  • Stress test: This test is used to see how the heart responds to physical activity. It may be done using exercise or medicine.
  • Imaging tests: These tests can help doctors see the heart and check for blockages in the coronary arteries. Tests may include a cardiac MRI, CT scan, or angiogram.

How is angina pectoris treated?

The goal of treatment is to relieve symptoms and improve blood flow to the heart. Treatment may include:

  • Lifestyle changes: These changes can include quitting smoking, exercising regularly, eating a healthy diet, and managing stress.
  • Medications: Medications can be used to treat angina and prevent future attacks. These include nitrates, beta-blockers, calcium channel blockers, and aspirin.
  • Surgery: Surgery may be needed to treat coronary artery disease. This can include angioplasty or stenting, which opens blocked arteries, or bypass surgery, which creates a new route for blood to flow around blocked arteries.

What are the complications of angina pectoris?

Angina pectoris can lead to other heart problems, such as:

  • Heart attack: This occurs when the blood flow to the heart is blocked.
  • Irregular heartbeats: These can include supraventricular tachycardia (SVT) and atrial fibrillation.
  • Heart failure: This is a condition in which the heart can’t pump enough blood to meet the body’s needs.
  • Cardiogenic shock: This is a medical emergency that occurs when the heart can’t pump enough blood to meet the body’s needs.

If you think you may be experiencing symptoms of angina pectoris, it’s important to see a doctor.

Prevention of angina pectoris

Preventing angina generally involves lifestyle changes and taking medications as prescribed. Lifestyle changes may include quitting smoking, eating a healthy diet, exercising regularly, maintaining a healthy weight, and managing stress.

Taking medications as prescribed may include taking nitroglycerin as directed for chest pain and taking beta blockers to prevent future attacks. If you have coronary artery disease, you may also need to take aspirin and statins.

Angina pectoris can be a serious condition, but with proper treatment and lifestyle changes, it can be managed. If you think you may be experiencing symptoms of angina pectoris, talk to your doctor.
