Angina occurs when the heart muscle does not get enough oxygen-rich blood. This can happen during physical activity or when a person is under stress. It can also occur during periods of rest. Angina is a type of chest pain that is caused by reduced blood flow to the heart muscle. It is usually described as a burning or squeezing sensation in the chest.
Types of Angina
There are two main types of angina: stable angina and unstable angina. Stable angina is the most common type of angina. It usually occurs during physical activity or when a person is under stress. It can also occur during rest, but it is usually relieved with rest. Unstable angina is more severe and occurs without any known trigger. It is often a sign of a heart attack and requires immediate medical attention.
Symptoms of Angina
The most common symptom of angina is a feeling of tightness, pressure, heaviness, or pain in the chest. This is often accompanied by pain or discomfort in the arms, shoulders, neck, jaw, or back. Other symptoms can include shortness of breath, nausea, fatigue, sweating, and lightheadedness.
Diagnosis of Angina
Angina is typically diagnosed with a physical exam and a medical history. Additional tests, such as an electrocardiogram (ECG) or a stress test, may be used to confirm the diagnosis. Treatment for angina usually involves lifestyle changes, such as quitting smoking and exercising regularly. Medications may also be used to reduce the symptoms of angina.
