Understanding Angina: A Comprehensive Guide

Angina is a type of chest pain caused by reduced blood flow to the heart. While not a disease itself, it's often a symptom of underlying heart disease, particularly coronary artery disease (CAD). Angina is typically described as squeezing, pressure, heaviness, tightness, or pain in the chest.


Angina is a cardiovascular condition indicating that the heart isn't receiving enough oxygen due to reduced blood flow. This reduced flow is typically caused by the narrowing or blockage of the coronary arteries, the vessels that supply the heart with blood.

There are different types of angina, including stable angina, unstable angina, variant angina, and microvascular angina. Each type has distinct characteristics and can indicate different levels of risk for heart attack and other cardiac issues.

Causes of Angina

The heart is a muscular organ that is approximately the size of a fist. It is located in the center of the chest, slightly tilted to the left. The heart is divided into four chambers: the left and right atria and the left and right ventricles. The atria are the upper chambers of the heart, and the ventricles are the lower chambers.

1.Physical exertion: Extra work can make the heart demand more oxygen, particularly when you're not used to regular exercise.

2.Emotional stress: Severe stress and negative emotions can raise blood pressure and speed the heart rate, increasing the heart's demand for oxygen.

3.Extreme temperatures: Cold weather and hot meals might cause blood vessels to narrow, reducing blood flow to the heart.

4.Smoking: This can damage and tighten blood vessels, impair circulation, and raise heart rate, which increases the heart's demand for oxygen.

Symptoms of Angina

Angina symptoms include:

- Chest pain or discomfort, possibly described as pressure, squeezing, burning, or fullness.

- Pain in arms, neck, jaw, shoulder, or back accompanying chest discomfort.

- Shortness of breath.

- Fatigue.

- Dizziness, weakness, or nausea.

Diagnosis of Angina

The following diagnostic tests may be used to diagnose angina:

Electrocardiogram (ECG):

This records electrical signals as they travel through the heart, indicating blocked or narrowed arteries.

Stress Testing:

This involves using a treadmill or medication to make the heart work harder and faster, monitored by an ECG.


This uses sound waves to produce images of the heart.

Coronary angiography and cardiac catheterization:

These visualize the heart's arteries and measure pressure and blood flow.

Precautions for Angina

Lifestyle modifications can help manage angina and improve heart health:

- Limiting physical exertion: People with angina should be cautious about overexertion.

- Healthy diet: A balanced, nutritious diet can promote heart health and manage underlying conditions that contribute to angina.

- Quitting smoking: Smoking damages the heart and blood vessels, so quitting is vital for heart health.

- Reducing alcohol: Too much alcohol can raise blood pressure, contributing to angina.

Treatment of Angina in India's Top Hospitals

Treatment for angina aims to relieve symptoms, slow the progression of heart disease, and reduce the risk of a heart attack. This typically involves lifestyle changes, medication, and in some cases, medical procedures:

- Lifestyle changes: Healthy habits include regular exercise, a heart-healthy diet, and quitting smoking.

- Medications: Doctors may prescribe nitrates, beta-blockers, calcium channel blockers, ranolazine, or aspirin to manage symptoms or reduce the risk of heart attack.

- Medical procedures: In some cases, doctors might recommend procedures like angioplasty, stent placement, or coronary artery bypass surgery.


Understanding angina and the heart disease it signals is essential to maintaining heart health. Regular check-ups, a healthy lifestyle, and appropriate treatments can help manage this condition and prevent severe complications.

Frequently Asked Questions

Angina is a symptom of an underlying heart condition, usually coronary heart disease.

While angina can be effectively managed with treatment, it's not curable as it's a symptom of underlying heart disease.

Angina itself is not life-threatening, but it's a warning sign of potential heart attack or other heart complications, which can be life-threatening.

Physical exertion can trigger angina symptoms by making the heart demand more oxygen.

Yes, maintaining a healthy lifestyle can help prevent angina by promoting heart health and reducing the risk of heart disease.

Emotional stress can trigger angina by raising blood pressure and heart rate, which increases the heart's demand for oxygen.

While angina isn't directly hereditary, some risk factors for angina and heart disease, such as high cholesterol levels and high blood pressure, can be genetic.

While more common in older adults, angina can occur in young adults, particularly with unhealthy lifestyle habits or genetic predisposition to heart disease.

Angina typically feels like pressure, squeezing, fullness, or pain in the chest, often spreading to the arms, neck, jaw, shoulder, or back.

Yes, an ECG, particularly when combined with a stress test, can detect signs indicative of angina.
