Angina is a type of chest pain that happens when your heart does not get enough oxygen-rich blood. Many people wonder about the difference between stable and unstable angina. Knowing the key differences can help you spot warning signs early and seek the right care. In this blog, we will explain stable vs. unstable angina, their symptoms, causes, and treatment options in simple terms.
What is Angina?
Angina is chest pain or discomfort caused by reduced blood flow to the heart. Usually, it feels like pressure, squeezing, or tightness in the chest. Sometimes, the pain spreads to the arms, neck, jaw, or back. Angina is a sign that your heart is not getting enough oxygen, often due to narrowed arteries. While angina is not a disease itself, it is a symptom of heart problems, especially coronary artery disease.
What is Stable Angina?
Stable angina is the most common type of angina. It usually happens during physical activity or stress. For example, you may feel chest pain when walking uphill or climbing stairs. The pain often goes away with rest or after taking medicine. Stable angina follows a regular pattern, so you can often predict when it will occur. Although it is serious, it is less dangerous than unstable angina.
What is Unstable Angina?
Unstable angina is more severe and unpredictable. It can happen at rest or with little effort. The pain may last longer, feel stronger, or come back again and again. Unlike stable angina, it does not follow a set pattern. Unstable angina is a medical emergency because it can lead to a heart attack. If you notice new or worsening chest pain, seek help right away.
