A condition marked by severe pain in the chest, often also spreading to the shoulders, arms, and neck, caused by an inadequate blood supply to the heart.
Any of a number of disorders in which there is intense localized pain.
In this article, we are going to be talking about pain related to your chest area and paying attention to heart health.
If you feel like you are having a heart attack:
Chew and swallow an aspirin, unless you are allergic to aspirin or have been told by your doctor never to take aspirin. Call 911 as soon as possible.
What is Angina?
Angina is a type of chest pain caused by reduced blood flow to the heart. Angina is a symptom of coronary artery disease.
Angina also called angina pectoris, is often described as squeezing, pressure, heaviness, tightness, or pain in your chest. Some people with angina symptoms say angina feels like a vise squeezing their chest or a heavy weight lying on their chest. Angina may be a new pain that needs to be checked by a doctor or recurring pain that goes away with treatment.
Although angina is relatively common, it can still be hard to distinguish from other types of chest pain, such as the discomfort of indigestion. If you have unexplained chest pain, seek medical attention right away.
Angina symptoms include chest pain and discomfort, possibly described as pressure, squeezing, burning, or fullness.
You may also have pain in your arms, neck, jaw, shoulder, or back.
Other symptoms that you may have with angina include:
- Shortness of breath
These symptoms need to be evaluated immediately by a doctor who can determine whether you have stable angina, or unstable angina, which can be a precursor to a heart attack.
Stable angina is the most common form of angina. It usually happens when you exert yourself and goes away with rest. For example, pain that comes on when you’re walking uphill or in the cold weather may be angina.
Characteristics of stable angina
- Develops when your heart works harder, such as when you exercise or climb stairs
- Can usually be predicted and the pain is usually similar to previous types of chest pain you’ve had
- Lasts a short time, perhaps five minutes or less
- Disappears sooner if you rest or use your angina medication
The severity, duration, and type of angina can vary. New or different symptoms may signal a more dangerous form of angina (unstable angina) or a heart attack.
Characteristics of unstable angina (a medical emergency)
- Occurs even at rest
- Is a change in your usual pattern of angina
- Is unexpected
- Is usually more severe and lasts longer than stable angina, maybe 30 minutes or longer
- May not disappear with rest or use of angina medication
- Might signal a heart attack
There’s another type of angina, called variant angina or Prinzmetal’s angina. This type of angina is rarer. It’s caused by a spasm in your heart’s arteries that temporarily reduces blood flow.
Characteristics of variant angina (Prinzmetal’s angina)
- Usually happens when you’re resting
- Is often severe
- May be relieved by angina medication
Angina in women
Symptoms of angina in women can be different from angina symptoms that occur in men. These differences may lead to delays in seeking treatment. For example, chest pain is a common symptom in women with angina, but it may not be the only symptom or the most prevalent symptom for women.
Women may also have symptoms such as:
- Shortness of breath
- Abdominal pain
- Discomfort in the neck, jaw, or back
- Stabbing pain instead of chest pressure
Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn’t getting enough oxygen, it causes a condition called ischemia.
The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD). Your heart (coronary) arteries can become narrowed by fatty deposits called plaques. This is called atherosclerosis.
During times of low oxygen demand — when you’re resting, for example — your heart muscle may still be able to function on the reduced amount of blood flow without triggering angina symptoms. But when you increase the demand for oxygen, such as when you exercise, angina can result.
- Stable angina. Stable angina is usually triggered by physical activity. When you climb stairs, exercise, or walk, your heart demands more blood, but narrowed arteries slow down blood flow. Besides physical activity, other factors such as emotional stress, cold temperatures, heavy meals, and smoking also can narrow arteries and trigger angina.
- Unstable angina. If fatty deposits (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 your heart muscle. Unstable angina can also be caused by blood clots that block or partially block your heart’s blood vessels. Unstable angina worsens and isn’t relieved by rest or your usual medications. If the blood flow doesn’t improve, your heart is starved of oxygen and a heart attack occurs. Unstable angina is dangerous and requires emergency treatment.
- Prinzmetal’s angina. This type of angina is caused by a sudden spasm in a coronary artery, which temporarily narrows the artery. This narrowing reduces blood flow to your heart, causing severe chest pain. Prinzmetal’s angina most often occurs at rest, typically overnight. Attacks tend to occur in clusters. Emotional stress, smoking, medications that tighten blood vessels (such as some migraine drugs), and use of the illegal drug cocaine may trigger Prinzmetal’s angina.
The following risk factors increase your risk of coronary artery disease and angina:
- Tobacco use. Chewing tobacco, smoking and long-term exposure to secondhand smoke damage the interior walls of arteries — including arteries to your heart — allowing deposits of cholesterol to collect and block blood flow.
- Diabetes. Diabetes increases the risk of coronary artery disease, which leads to angina and heart attacks by speeding up atherosclerosis and increasing your cholesterol levels.
- High blood pressure. Over time, high blood pressure damages arteries by accelerating the hardening of the arteries.
- High blood cholesterol or triglyceride levels. Cholesterol is a major part of the deposits that can narrow arteries throughout your body, including those that supply your heart. A high level of low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol, increases your risk of angina and heart attacks. A high level of triglycerides, a type of blood fat related to your diet, also is unhealthy.
- Family history of heart disease. If a family member has coronary artery disease or has had a heart attack, you’re at a greater risk of developing angina.
- Older age. Men older than 45 and women older than 55 have a greater risk than do younger adults.
- Lack of exercise. An inactive lifestyle contributes to high cholesterol, high blood pressure, type 2 diabetes, and obesity. However, it is important to talk with your doctor before starting an exercise program.
- Obesity. Obesity is linked with high blood cholesterol levels, high blood pressure, and diabetes, all of which increase your risk of angina and heart disease. If you’re overweight, your heart has to work harder to supply blood to the body.
- Stress. Stress can increase your risk of angina and heart attacks. Too much stress, as well as anger, also can raise your blood pressure. Surges of hormones produced during stress can narrow your arteries and worsen angina.
The chest pain that occurs with angina can make doing some normal activities, such as walking, uncomfortable. However, the most dangerous complication is a heart attack.
Common signs and symptoms of a heart attack include:
- Pressure, fullness, or a squeezing pain in the center of your chest that lasts for more than a few minutes
- Pain extending beyond your chest to your shoulder, arm, back, or even to your teeth and jaw
- Increasing episodes of chest pain
- Nausea and vomiting
- Prolonged pain in the upper abdomen
- Shortness of breath
- An impending sense of doom
If you have any of these symptoms, seek emergency medical attention immediately.
You can help prevent angina by making the same lifestyle changes that might improve your symptoms if you already have angina. These include:
- Quitting smoking.
- Monitoring and controlling other health conditions, such as high blood pressure, high cholesterol, and diabetes.
- Eating a healthy diet and maintaining a healthy weight.
- Increasing your physical activity after you get your doctor’s OK. Aim for 150 minutes of moderate activity each week. Plus, it’s recommended that you get 10 minutes of strength training twice a week and to stretch three times a week for five to 10 minutes each time.
- Reducing your stress level.
- Limiting alcohol consumption to two drinks or fewer a day for men, and one drink a day or less for women.
- Getting the annual flu shot to avoid heart complications from the virus.
If You Are Suffering From Chest Pain, Please See A Doctor As Soon As Possible
To diagnose angina, your doctor will start by doing a physical exam and asking about your symptoms. You’ll also be asked about any risk factors, including whether you have a family history of heart disease.
There are several tests your doctor may order to help confirm whether you have angina:
- Electrocardiogram (ECG or EKG). Each beat of your heart is triggered by an electrical impulse generated from special cells in your heart. An electrocardiogram records these electrical signals as they travel through your heart. Your doctor can look for patterns among these heartbeats to see if the blood flow through your heart has been slowed or interrupted or if you’re having a heart attack.
- Stress test. Sometimes angina is easier to diagnose when your heart is working harder. During a stress test, you exercise by walking on a treadmill or pedaling a stationary bicycle. Your blood pressure and ECG readings are monitored as you exercise. Other tests also may be done at the same time as a stress test. If you’re unable to exercise, you may be given drugs that cause your heart to work harder to simulate exercising followed by an imaging test.
- Echocardiogram. An echocardiogram uses sound waves to produce images of the heart. Your doctor can use these images to identify angina-related problems, including heart muscle damage due to poor blood flow. An echocardiogram can be given during a stress test, and this can show if there are areas of your heart that are not getting enough blood.
- Nuclear stress test. A nuclear stress test helps measure blood flow to your heart muscle at rest and during stress. It is similar to a routine stress test, but during a nuclear stress test, a radioactive substance is injected into your bloodstream. This substance mixes with your blood and travels to your heart. A special scanner — which detects the radioactive material in your heart — shows how the substance moves with the blood in your heart muscle. Poor blood flow to any part of your heart can be seen in the images because not as much of the radioactive substance is getting there.
- Chest X-ray. This test takes images of your heart and lungs. This is to look for other conditions that might explain your symptoms and to see if you have an enlarged heart.
- Blood tests. Certain heart enzymes slowly leak out into your blood if your heart has been damaged by a heart attack. Samples of your blood can be tested for the presence of these enzymes.
- Coronary angiography. Coronary angiography uses X-ray imaging to examine the inside of your heart’s blood vessels. It’s part of a general group of procedures known as cardiac catheterization. During coronary angiography, a type of dye that’s visible by X-ray machine is injected into the blood vessels of your heart. The X-ray machine rapidly takes a series of images (angiograms), offering a detailed look at the inside of your blood vessels.
- Cardiac computerized tomography (CT) scan. In a cardiac CT scan, you lie on a table inside a doughnut-shaped machine. An X-ray tube inside the machine rotates around your body and collects images of your heart and chest, which can show if any of your heart’s arteries are narrowed or if your heart is enlarged.
- Cardiac MRI. In a cardiac MRI, you lie on a table inside a long, tubelike machine that produces detailed images of your heart’s structure and its blood vessels.
There are many options for angina treatment, including lifestyle changes, medications, angioplasty, and stenting, or coronary bypass surgery. The goals of treatment are to reduce the frequency and severity of your symptoms and to lower your risk of a heart attack and death.
However, if you have unstable angina or angina pain that’s different from what you usually have, such as occurring when you’re at rest, you need immediate treatment in a hospital.
If lifestyle changes alone don’t help your angina, you may need to take medications. These may include:
- Nitrates. Nitrates are often used to treat angina. Nitrates relax and widen your blood vessels, allowing more blood to flow to your heart muscle. You might take a nitrate when you have angina-related chest discomfort, before doing something that normally triggers angina (such as physical exertion) or on a long-term preventive basis. The most common form of nitrate used to treat angina is nitroglycerin tablets, which you put under your tongue.
- Aspirin. Aspirin reduces the ability of your blood to clot, making it easier for blood to flow through narrowed heart arteries. Preventing blood clots can also reduce your risk of a heart attack. But don’t start taking a daily aspirin without talking to your doctor first.
- Clot-preventing drugs. Certain medications such as clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta) can help prevent blood clots from forming by making your blood platelets less likely to stick together. One of these medications may be recommended if you can’t take aspirin.
- Beta-blockers. Beta-blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. As a result, the heart beats more slowly and with less force, thereby reducing blood pressure. Beta-blockers also help blood vessels relax and open up to improve blood flow, thus reducing or preventing angina.
- Statins. Statins are drugs used to lower blood cholesterol. They work by blocking a substance your body needs to make cholesterol. They may also help your body reabsorb cholesterol that has accumulated in plaques in your artery walls, helping prevent further blockage in your blood vessels. Statins also have many other beneficial effects on your heart arteries.
- Calcium channel blockers. Calcium channel blockers, also called calcium antagonists, relax and widen blood vessels by affecting the muscle cells in the arterial walls. This increases blood flow in your heart, reducing or preventing angina.
- Blood pressure-lowering medications. If you have high blood pressure, diabetes, signs of heart failure, or chronic kidney disease, your doctor will likely prescribe a medication to lower your blood pressure. There are two main classes of drugs to treat blood pressure: angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs).
- Ranolazine (Ranexa). Ranexa can be used alone or with other angina medications, such as calcium channel blockers, beta-blockers, or nitroglycerin.
Medical procedures and surgery
Lifestyle changes and medications are frequently used to treat stable angina. But medical procedures such as angioplasty, stenting, and coronary artery bypass surgery may also be used to treat angina.
- Angioplasty and stenting. During an angioplasty — also called a percutaneous coronary intervention (PCI) — a tiny balloon is inserted into your narrowed artery. The balloon is inflated to widen the artery, and then a small wire mesh coil (stent) is usually inserted to keep the artery open. This procedure improves blood flow in your heart, reducing or eliminating angina. Angioplasty and stenting is a good treatment option if you have unstable angina or if lifestyle changes and medications don’t effectively treat your chronic, stable angina.
- Coronary artery bypass surgery. During coronary artery bypass surgery, a vein or artery from somewhere else in your body is used to bypass a blocked or narrowed heart artery. Bypass surgery increases blood flow to your heart and reduces or eliminates angina. It’s a treatment option for both unstable anginas as well as stable angina that has not responded to other treatments.
- External counterpulsation (ECP). With ECP, blood pressure-type cuffs are placed around the calves, thighs, and pelvis to increase blood flow to the heart. ECP requires multiple treatment sessions. The American College of Cardiology, American Heart Association, and other heart organizations say ECP may help reduce symptoms in people with refractory angina.
Lifestyle and home remedies
Because heart disease is often the cause of angina, you can reduce or prevent angina by working on reducing your heart disease risk factors. Making lifestyle changes is the most important step you can take.
- If you smoke, stop smoking. Avoid exposure to secondhand smoke.
- If you’re overweight, talk to your doctor about weight-loss options.
- Eat a healthy diet with limited amounts of saturated fat, lots of whole grains, and many fruits and vegetables.
- Talk to your doctor about starting a safe exercise plan.
- Because angina is often brought on by exertion, it’s helpful to pace yourself and take rest breaks.
- Treat diseases or conditions that can increase your risk of angina, such as diabetes, high blood pressure, and high blood cholesterol.
- Avoid large meals that make you feel overly full.
- Avoiding stress is easier said than done, but try to find ways to relax. Talk with your doctor about stress-reduction techniques.
- Limit alcohol consumption to two drinks or fewer a day for men, and one drink a day or less for women.
Please seek medical help as soon as possible. If you are suffering from severe chest pain it is recommended you chew 2 mg Asprin and call 911.
