Angina: Understanding, Recognizing, and Managing Chest Discomfort

Angina, a condition characterized by chest discomfort or pain, can be concerning. Angina pectoris is another name for angina. Squeezing, heaviness, pressure, discomfort, or tightness in the chest are all common symptoms of angina. It may appear as if a heavy weight is pressing on your chest. Angina can be a sudden pain that necessitates medical attention or a chronic soreness that subsides with treatment.

Although angina is relatively prevalent, it can be difficult to distinguish from other types of chest pain, such as indigestion discomfort.

What Causes Angina?

1.  Coronary Artery Disease (CAD): The most common cause is CAD. It involves the narrowing of coronary arteries, reducing blood flow to the heart muscle.

2.  Coronary Spasm: Spasms in coronary arteries can temporarily reduce blood flow, leading to angina episodes.

3.  Microvascular Angina: A type of angina caused by abnormalities in the tiny blood vessels of the heart.

4.  Physical Exertion: Angina can be triggered by physical activity that demands more oxygen from the heart.

What are the Symptoms of Angina?

Symptoms may include:

1.  Chest Discomfort: Described as pressure, squeezing, heaviness, or burning in the chest. Angina discomfort typically lasts for a few minutes.

2.  Pain in Other Areas: Discomfort may also be felt in the arms, shoulders, neck, jaw, or back.

3.  Shortness of Breath: Difficulty breathing may accompany chest discomfort during angina episodes.

4.  Nausea and Fatigue: Some individuals may experience nausea and fatigue during angina episodes.

What are the Different Types of Angina?

There are various types of angina. The type is determined by the underlying reason and if rest or medication relieves symptoms.

1.  Stable Angina: Typically triggered by physical exertion or stress and relieved by rest or medication. It’s the most common form of angina. 

This type is predictable and often resembles past episodes of chest discomfort. The chest pain is usually brief, lasting around five minutes or less.

2.  Unstable Angina: Unstable angina unpredictably occurs at rest or worsens, happening with less physical effort. It is typically severe. It can last longer than stable angina, possibly lasting 20 minutes or more. 

The pain does not subside with rest or usual angina medications. If blood flow does not improve, it starves the heart of oxygen. This can lead to a heart attack. Unstable angina demands emergency treatment as it poses a dangerous situation.

3.  Variant (Prinzmetal’s) Angina: Variant angina, is also known as Prinzmetal angina. It results from a spasm in the heart’s arteries, temporarily reducing blood flow. 

The primary symptom of this type of chest discomfort is severe chest pain. It often occurs in cycles, predominantly at rest and during the night. 

The pain may be eased with medication. Coronary artery disease is not the cause of variant angina. Instead, it is attributed to arterial spasms in the heart.

How is Angina Diagnosed?

1.  Medical History and Physical Examination: An initial step to assess symptoms, risk factors, and medical history.

2.  Electrocardiogram (ECG/EKG): Records the heart’s electrical activity, helping identify abnormal patterns.

3.  Stress Test: Evaluates heart function during physical activity, revealing exercise-induced angina.

4.  Coronary Angiography: Invasive procedure using dye and X-rays to assess coronary arteries’ condition.

What are the Treatment Options for Angina?

Treatment options may include:

1.  Lifestyle Modifications: You can help prevent this condition by making some lifestyle changes like:

·      Eating a healthy diet

·      Not smoking

·      Maintaining a healthy weight

·      Exercising regularly

·      Reducing stress

·      Managing other health conditions

2.  Medications: The following medications can help manage this condition:

·      Nitroglycerin

·      beta-blockers

·      calcium channel blockers

3.  Angioplasty and Stent Placement: This is a minimally invasive procedure. It is used to widen narrowed arteries and improve blood flow.

4.  Coronary Artery Bypass Grafting (CABG): Rerouting blood flow around constricted or obstructed coronary arteries using surgery.

Angina can be a challenging condition, but with knowledge, awareness, and proactive measures, you can effectively manage this condition.
