Angina is a symptom of heart disease and is characterised by chest pain or discomfort. It occurs when the heart does not receive enough oxygen-rich blood, causing it to beat faster and harder to gain more blood, resulting in noticeable pain. Angina can feel like a pressing, squeezing, or crushing pain in the chest under the breastbone, and the discomfort may spread to other parts of the upper body, such as the arms, neck, jaw, or earlobes. While angina is not a disease in itself, it is a warning sign of underlying heart issues and can be a precursor to a heart attack. Therefore, it is important to seek medical attention and manage risk factors to prevent further complications.

What You'll Learn
Angina is chest pain or discomfort
People with angina experience pain, pressure, or a squeezing sensation in their chest, under the breastbone. This discomfort may spread to other parts of the upper body, including the arms, neck, jaw, or earlobes. Angina can also cause shortness of breath, weakness, and fatigue, as well as nausea, vomiting, and excessive sweating.
The pain associated with angina comes and goes and is typically relieved within a few minutes by resting or taking prescribed medication, such as nitroglycerin. Stable angina, the most common type, follows predictable patterns and is caused by CAD. Unstable angina, on the other hand, indicates a change in symptoms and requires immediate medical attention as it may signal an impending heart attack.
The risk factors for angina are similar to those for heart disease and include high blood pressure, smoking, high cholesterol levels, lack of exercise, excess weight, and a diet high in saturated fat. It is important to note that angina can be a symptom of other conditions, and not all cases are related to CAD. Microvascular angina, for example, is caused by poor function of tiny blood vessels leading to the heart, arms, and legs, and is more common in women.
If you experience chest pain, it is crucial to seek medical advice to determine the underlying cause and receive appropriate treatment.

It is a symptom of coronary heart disease
Angina is chest pain or discomfort that comes and goes. It is a symptom of coronary heart disease, specifically coronary artery disease (CAD). Angina occurs when the heart muscle doesn't receive enough oxygen-rich blood and can be a precursor to a heart attack. It is important to note that angina itself does not cause permanent damage to the heart, unlike a heart attack.
There are several types of angina, with stable angina (angina pectoris) being the most common type. It is caused by a temporary reduction in blood flow to the heart due to problems with the coronary arteries. This can include plaque buildup, narrowing or hardening of the arteries, or coronary artery spasms. Stable angina can be managed with rest and medication, such as nitroglycerin, and does not require emergency care unless the pain suddenly worsens or becomes persistent.
Unstable angina, on the other hand, is a more urgent matter. It occurs when the symptoms change suddenly, indicating a higher risk of a heart attack. If you experience unstable angina, it is crucial to seek emergency medical treatment to prevent a potential heart attack.
The pain associated with angina can feel like pressing, squeezing, or crushing sensations in the chest under the breastbone. This discomfort may radiate to other parts of the upper body, including the arms, neck, upper back, or earlobes. Additionally, individuals with angina may experience shortness of breath, weakness, or fatigue.
It is important to consult a healthcare provider if you experience any symptoms of angina. They can diagnose angina through a physical examination, evaluation of symptoms, and medical history. Tests such as an electrocardiogram (ECG) and stress test may also be performed to confirm the diagnosis and assess the severity of the condition.

It occurs when the heart needs more oxygen-rich blood
Angina is the medical term for chest pain or discomfort due to coronary heart disease. It is caused by a lack of oxygen-rich blood reaching the heart muscle, known as myocardial ischemia. This can be due to a variety of factors, including coronary artery disease (CAD), during which plaque builds up and narrows the arteries, reducing blood flow.
The heart requires a continuous supply of oxygen-rich blood to function optimally. Oxygen-rich blood travels from the lungs to the left atrium through pulmonary veins. From there, it passes through the mitral valve into the left ventricle. When the left ventricle is full, it contracts, closing the mitral valve and opening the aortic valve. The heart then pumps oxygen-rich blood through the aortic valve and into the aorta, the body's main artery. The aorta branches into smaller arteries, delivering oxygenated blood to the entire body.
Myocardial oxygen demand refers to the amount of oxygen the heart requires to function optimally. Heart rate is considered the most critical factor influencing myocardial oxygen demand. An increased heart rate shortens the cardiac cycle, reducing the time spent in diastole. This decrease in diastolic time lessens the amount of blood filling the ventricles, resulting in oxygen-saturated hemoglobin being unable to reach the subendocardium. Consequently, the myocardium must work harder to complete the cardiac cycle efficiently.
During the later stages of coronary artery disease, a rise in myocardial oxygen demand can exceed the oxygen supply, resulting in angina. This typically occurs during physical activity or stress when the heart requires more oxygen. The chest pain associated with angina can be managed by resting or taking medication. However, if the pain persists at rest or while sleeping, it may indicate unstable angina, requiring emergency medical treatment to prevent a heart attack.
To summarise, angina occurs when the heart muscle is deprived of sufficient oxygen-rich blood, leading to chest pain or discomfort. It is essential to seek medical attention for chest pain to determine the underlying cause and receive appropriate treatment.

Angina pectoris is the most common type
Angina is the medical term for chest pain or discomfort due to coronary heart disease. It is not a disease in itself but a symptom and a warning sign of heart disease. Angina pectoris, another name for stable angina, is the most common type. It occurs when the heart muscle does not get enough blood and oxygen, a condition known as ischemia. This can be due to several problems with the coronary arteries, such as plaque buildup, narrowing, or blockage, which reduce blood flow to the heart.
People with angina pectoris typically describe a pressing, squeezing, or crushing sensation in their chest under the breastbone. This discomfort can radiate to other parts of the upper body, including the neck, jaw, shoulders, arms, back, or abdomen. Some individuals may experience associated symptoms like nausea, vomiting, shortness of breath, sweating, weakness, or fatigue.
The pain and discomfort associated with angina pectoris can be managed through various treatments. Nitroglycerin is a commonly prescribed medication that helps to quickly open up blood vessels, thereby increasing blood flow to the heart. It can be taken daily to prevent angina or as needed during angina episodes. Other medications used to treat angina include beta-blockers and calcium channel blockers, which help relax blood vessels and improve blood flow.
In addition to medication, managing angina pectoris involves addressing risk factors and maintaining a healthy lifestyle. This includes controlling high blood pressure, high cholesterol levels, smoking cessation, regular exercise, weight management, and adopting a healthy diet low in saturated fat. Keeping a log of angina episodes, including symptoms, triggers, and pain levels, can also help individuals better understand and manage their condition.
While treatments can help reduce the frequency and intensity of angina pectoris episodes, some people may still experience angina pain. It is important to work closely with a healthcare provider to determine the underlying cause and develop an appropriate treatment plan. Additionally, individuals should be aware of the difference between stable and unstable angina, as the latter may require emergency medical attention to prevent a heart attack.

It can be treated with medication and rest
Angina is a symptom of heart disease and is characterised by chest pain or discomfort due to a lack of oxygen-rich blood reaching the heart. While angina is not a disease in itself, it can be a warning sign of heart disease. It is important to get chest pain checked out by a healthcare professional, as it could be a symptom of angina or another cardiovascular condition.
If you are experiencing angina, there are a number of treatment options available to help manage the pain and reduce how often it occurs. Medication can be used to treat angina, including anticoagulants or antiplatelet drugs to prevent blood clots, blood pressure medication, and cholesterol medication. Nitroglycerin is a common medication used to quickly open blood vessels during an angina attack. In addition to medication, lifestyle changes can also help to manage angina. This includes addressing triggers such as stress, diet, alcohol consumption, exposure to air pollution, physical inactivity, and smoking.
Rest is also an important part of managing angina. Learning your triggers and knowing when to rest can help you manage the condition. However, it is important to note that if your stable angina suddenly becomes worse or doesn't go away with rest or treatment, you should seek emergency medical help as it could be a sign of a heart attack.
In addition to medication and rest, there are other treatments for angina. These include coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), also known as coronary angioplasty and stenting. Enhanced external counterpulsation (EECP) is another treatment option, which involves applying pressure to the lower legs to improve blood flow to the heart.
