Angina is chest pain that happens because there isn’t enough blood going to part of your heart. It can feel like a heart attack, with pressure or squeezing in your chest. It’s sometimes called angina pectoris or ischemic chest pain.
It’s a symptom of heart disease, and it happens when something blocks your arteries or there’s not enough blood flow in the arteries that bring oxygen-rich blood to your heart.
Angina usually goes away quickly. Still, it can be a sign of a life-threatening heart problem. It’s important to find out what’s going on and what you can do to avoid a heart attack.
Usually, medicine and lifestyle changes can control angina. If it’s more severe, you may need surgery, too. Or you may need what’s called a stent, a tiny tube that props open arteries.
There are different types of angina:
This is the most common. Physical activity or stress can trigger it. It usually lasts a few minutes, and it goes away when you rest.
It isn’t a heart attack, but it can be a sign that you’re more likely to have one. Tell your doctor if this happens to you. Click Here : Exenta 50
1. Unstable angina.
You can have this while you’re at rest or not very active. The pain can be strong and long-lasting, and it may come back again and again.
It can be a signal that you’re about to have a heart attack, so see a doctor right away.
2. Microvascular angina.
With this type, you have chest pain but no coronary artery blockage. Instead, it happens because your smallest coronary arteries aren’t working the way they should, so your heart doesn’t get the blood it needs. The chest pain usually lasts more than 10 minutes. This type is more common in women.
3. Prinzmetal’s angina (variant angina).
This type is rare. It might happen at night while you’re sleeping or resting.
Your heart arteries suddenly tighten or narrow.
It can cause a lot of pain, and you should get it treated. click here : Trivedon MR
What is stable angina?
Stable angina (angina pectoris) is a type of chest pain that happens when your heart muscle needs more oxygen than usual but it’s not getting it at that moment because of heart disease.
This can happen when it’s cold outside or you’re exercising, for example.
Stable angina is a temporary chest pain, but it can eventually lead to acute coronary syndrome.
How common is stable angina?
About 10 million Americans have angina. Stable angina is the most common type.
Older adults who have heart disease usually get stable angina.
The difference between stable vs. unstable angina
- Lasts the same length of time each time it happens.
- Has the same cause each time.
- Happens regularly.
- Doesn’t have the same length or cause each time.
- Is unpredictable.
- Can happen when you’re not moving.
Stable angina can turn into unstable angina. Signs of this include having chest pain that:
- Happens when you’re at rest.
- Goes on for at least 15 minutes.
- Doesn’t go away after you take nitroglycerin. (You may need a bigger dose of nitroglycerin to relieve it.)
What causes stable angina?
In most cases, coronary artery disease causes stable angina when you exert yourself or feel stressed.
If a blood clot or atherosclerosis creates a block or obstacle in your coronary artery, this limits the amount of blood that can get to your heart muscle. Click Here : Ranozex
Other causes include:
- Heart failure.
- Problems with your heart valves.
- Problems with your heart rhythm.
Angina usually happens because of heart disease. A fatty substance called plaque builds up in your arteries, blocking blood flow to your heart muscle.
This forces your heart to work with less oxygen. That causes pain. You may also have blood clots in the arteries of your heart, which can cause heart attacks.
Less common causes of chest pain include:
- A blockage in a major artery of your lungs (pulmonary embolism)
- An enlarged or thickened heart (hypertrophic cardiomyopathy)
- Narrowing of a valve in the main part of your heart (aortic stenosis)
- Swelling of the sac around your heart (pericarditis)
- Tearing in the wall of your aorta, the largest artery in your body (aortic dissection)
Angina is caused by reduced blood flow to the heart muscle. Blood carries oxygen, which the heart muscle needs to survive.
When the heart muscle isn’t getting enough oxygen, it causes a condition called ischemia.
The most common cause of reduced blood flow to the heart muscle is coronary artery disease (CAD). The heart (coronary) arteries can become narrowed by fatty deposits called plaques.
This is called atherosclerosis.
If plaques in a blood vessel rupture or a blood clot forms, it can quickly block or reduce flow through a narrowed artery.
This can suddenly and severely decrease blood flow to the heart muscle.
During times of low oxygen demand — when resting, for example — the heart muscle may still be able to work on the reduced amount of blood flow without triggering angina symptoms.
But when the demand for oxygen goes up, such as when exercising, angina can result.
A person can treat an episode of stable angina by resting or taking medication if necessary. However, long-term treatment will focus on making changes to reduce the chances of further incidents.
Treatment may include:
Nitroglycerin is a standard medicine for relieving the pain from stable angina. It relaxes coronary arteries, which reduces the workload of the heart.
A person may need to carry nitroglycerin with them at all times. Doctors will recommend a specific dosage, depending on a person’s symptoms and overall health.
A doctor may also prescribe medications to treat underlying conditions, such as high blood pressure or high cholesterol, to reduce the risk of an episode.
If doctors believe blood clots are an underlying risk, they may recommend blood thinners to help prevent blockages in the arteries.
Doctors will usually recommend that a person makes healthful lifestyle choices, such as eating a varied diet rich in whole grains, fruits, and vegetables.
They may also tell the person to look into stress-reducing techniques, such as yoga, meditation, or breathing exercises.
Light exercises or physical therapy can also help reduce symptoms and slowly increase the physical activity a person can handle over time.
Health-creating lifestyle choices may also reduce the risk of high cholesterol and high blood pressure.
An angioplasty is a common surgical procedure used to treat stable angina. It involves locating the problem area in the artery, then adding a permanent stent to widen it and hold it open.
Angioplasty is a minimally invasive procedure, which should help prevent symptoms.
More invasive surgeries may be necessary in some cases. These can include procedures such as a coronary artery bypass to replace damaged or blocked pieces of the artery.

The outlook for people with stable angina can vary but is usually good. Medication is often enough to manage symptoms, and when a person makes healthful lifestyle changes, it can help improve their quality of life, reduce their risk factors, and prevent symptoms from getting worse.
Symptoms may get worse, and a person’s risk of developing other conditions may also increase if they do not make positive lifestyle choices.
Similarly, episodes of stable angina may continue, and people may develop a greater risk for severe complications, such as a heart attack or unstable angina.
Making positive lifestyle changes is a start, but it is still vital to see a doctor at the first sign of stable angina symptoms. Working directly with a doctor to manage symptoms, as soon as they show up, may give a person the best outlook possible.
