Angina, sometimes called angina pectoris, is a symptom of reduced blood flow to the heart, which can be caused by coronary heart disease. It is characterised by chest pain or discomfort that comes and goes, often triggered by physical activity or stress. While angina itself is not dangerous, it can be a warning sign of a heart attack or other heart problems. In terms of muscle pain, angina typically causes pain or discomfort in the chest, jaw, arms, shoulders, neck, back, or stomach. This pain can feel like pressure, tightness, or squeezing and may radiate to other parts of the upper body. However, it is important to note that angina does not always present as intense pain, and some people may experience vague discomfort or a dull ache instead.

Angina is chest pain or discomfort due to coronary heart disease
Angina is a symptom of coronary heart disease, which involves reduced blood flow to the heart. It is characterised by chest pain or discomfort that comes and goes. While it is not dangerous in and of itself, angina can be a warning sign of a heart attack. Therefore, it is important to seek medical care if you are experiencing angina.
The pain associated with angina can be mild or more severe, and it may feel like tightness, squeezing, or pressure in the chest. Some people may experience a dull ache or a burning sensation, similar to heartburn or indigestion. The discomfort may spread to other parts of the upper body, including the jaw, teeth, shoulders, arms, neck, back, or stomach. In some cases, individuals may experience related symptoms such as nausea, fatigue, or cold sweats.
There are different types of angina, including stable angina, unstable angina, and microvascular angina. Stable angina is typically triggered by physical activity and follows predictable patterns, with each episode lasting for a short duration (usually five minutes or less). It can be managed through rest, medication, or lifestyle changes. Unstable angina, on the other hand, is more severe, unpredictable, and may not respond to rest or medication. It requires urgent medical attention as it can indicate an impending heart attack. Microvascular angina is caused by problems with the smallest blood vessels in the heart and can be more common in women, especially during menopause.
The treatment for angina aims to address the underlying cause of reduced blood flow to the heart. This may involve surgical procedures such as percutaneous coronary intervention (PCI) or angioplasty to widen or bypass the affected arteries, improving blood flow to the heart. Cardiac rehabilitation programmes may also be recommended, which include exercise training and education to reduce the risk of future heart problems. Additionally, individuals with angina can benefit from keeping a log of their angina episodes, tracking triggers, and working with their healthcare provider to manage their condition in their daily lives.

Stable angina can be managed with medication and lifestyle changes
Angina is the medical term for chest pain or discomfort due to coronary heart disease. Stable angina is a type of chest pain that lasts up to five minutes and often occurs during exertion or emotional stress. It is caused by poor blood flow through the coronary arteries, which supply oxygen-rich blood to the heart. Stable angina is a warning sign that an individual may be at risk of a heart attack in the future.
Stable angina can be managed through a combination of medication and lifestyle changes. While it is important to seek medical advice and treatment, there are also self-care measures that can help improve symptoms and reduce the risk of future heart problems. Here are some strategies to manage stable angina:
Medication
Medications can help improve blood flow to the heart and manage other medical conditions that contribute to stable angina. Here are some options:
- Nitroglycerin: This medication can help treat an angina episode as it is happening. It is often recommended as a quick-acting treatment to provide relief.
- Aspirin Therapy: Taking a low dose of aspirin (75 to 325 mg) daily may help prevent heart attacks in some individuals. However, it is important to discuss this with a healthcare provider to ensure the benefits outweigh the risks of side effects.
- Other Blood-Thinning Medications: In addition to aspirin, other blood-thinning therapies, such as clopidogrel, ticagrelor, or prasugrel, may be recommended to help prevent heart attacks.
- Statins: These medications can help manage high cholesterol, which is a risk factor for heart disease and stable angina.
Lifestyle Changes
Making healthy lifestyle changes can help prevent angina attacks and improve overall heart health:
- Exercise: Regular physical activity can help improve cardiovascular health and reduce the risk of angina attacks. It is important to start slowly and consult with a healthcare provider about the appropriate type and intensity of exercises.
- Stress Management: Since stress can trigger angina episodes, finding healthy ways to manage stress, such as through relaxation techniques, meditation, or yoga, can be beneficial.
- Healthy Diet: Adopting a heart-healthy diet, such as the DASH diet or a Mediterranean-style diet, can help lower cholesterol levels and improve overall heart health.
- Smoking Cessation: Quitting smoking is crucial for improving heart health and reducing the risk of angina attacks.
- Weight Management: Maintaining a healthy weight can help reduce stress on the heart. Losing weight, if necessary, through a combination of a healthy diet and regular exercise, can be beneficial.
It is important to work closely with a healthcare provider to determine the most appropriate treatment plan for stable angina. While medication can help manage symptoms, lifestyle changes are crucial for long-term management and reducing the risk of future heart complications.

Unstable angina is a medical emergency
Angina is the medical term for chest pain or discomfort due to coronary heart disease. While angina itself is not life-threatening, unstable angina is a medical emergency. Unstable angina is a warning sign that a heart attack may occur soon and needs to be treated right away. It is caused by narrowed arteries, which reduce blood flow to the heart due to fatty deposits. These deposits can rupture, leading to blood clots that block the flow of blood to the heart.
Unstable angina causes unexpected chest pain that often gets worse over a short period of time. It usually occurs while resting and can be a symptom of more severe heart disease. If you are experiencing new, worsening, or persistent chest discomfort, you should call emergency services. Other symptoms that require immediate medical attention include trouble taking heart medications, abnormal heart rhythms, and shortness of breath.
To diagnose unstable angina, a healthcare professional will perform a physical examination and check your blood pressure. They may also recommend tests such as an EKG, blood tests, echocardiogram, or coronary angiogram to assess the severity of the condition. Treatment options may include percutaneous coronary intervention (PCI) to open blocked arteries, coronary artery bypass graft surgery for severe blockages, and medications to prevent blood clots and improve blood flow to the heart.
Making healthy lifestyle changes can also help prevent unstable angina. This includes taking medications such as aspirin or other blood-thinning therapies to prevent heart attacks. It is important to discuss these options with a healthcare provider to determine if the benefits outweigh the risks of potential side effects.

Microvascular angina is caused by problems with small blood vessels in the heart
Angina is the medical term for chest pain or discomfort due to coronary heart disease. Microvascular angina is a type of angina that occurs due to problems with the small blood vessels that supply oxygen-rich blood to the heart. These small vessels, known as coronary microvasculature, are a crucial part of the heart's blood supply.
Microvascular angina is characterised by pain or discomfort in the chest, typically during physical activity or when under stress. This pain usually lessens when the person is at rest. However, in some cases, spasms in the small blood vessels can cause pain during rest as well. The discomfort associated with microvascular angina has been described as a feeling of heaviness, tightness, pressure, or squeezing in the chest, and it can last for at least 15 minutes.
The underlying cause of microvascular angina lies in the dysfunction of the smallest coronary artery blood vessels. These tiny blood vessels can experience spasms, leading to reduced blood flow and insufficient oxygen delivery to the heart muscle. This lack of oxygen can result in damage to the heart muscle, and if left untreated, it can lead to myocardial ischemia, a condition where the heart doesn't receive enough oxygenated blood.
Coronary microvascular disease (MVD) is the medical term for the condition affecting these small blood vessels. MVD can be challenging to diagnose, as standard tests for heart disease may not always detect it. Advanced imaging techniques, such as PET scans, cardiac catheterization, and cardiac MRI with perfusion, are often employed to visualise blood flow and identify MVD in these tiny blood vessels.
The treatment for microvascular angina aims to manage the condition and prevent complications. It typically involves a combination of prescription medications and lifestyle modifications. Medications can help improve blood vessel function and lower the risk of problems associated with reduced blood flow. Lifestyle changes may include managing risk factors such as high blood pressure, high cholesterol, and diabetes.

Angina can be treated with medication and surgery
Angina is a medical term for chest pain or discomfort due to coronary heart disease. It is a symptom of reduced blood flow to the heart, which can lead to a heart attack if left untreated. Angina pain can occur when the heart is working hard or when one is at rest.
In addition to medication, providers may recommend procedures or surgery to treat angina. If the coronary arteries are narrow or blocked, a provider may insert a small balloon and tube (stent) to reopen the artery and allow blood to flow through. They can also create a new path around blockages.
Treating angina also involves addressing the underlying condition causing it. This may involve a combination of medicines, procedures, and changes to daily habits. Lifestyle changes that can help treat angina include eating heart-healthy foods, increasing physical activity, quitting smoking, and limiting alcohol consumption.
It is important to seek medical care if you are experiencing angina. A healthcare provider will work to treat your symptoms and the underlying cause to prevent dangerous complications such as a heart attack or cardiac arrest.
