Angina pectoris is a medical condition that is characterized by chest pain or discomfort, which occurs when the heart muscle does not receive enough oxygen-rich blood. This condition is often described as a squeezing, pressure, burning, or tightness sensation in the chest that may also spread to the arms, neck, jaw, shoulders, or back. Angina pectoris is a common symptom of coronary artery disease (CAD), which is the most common type of heart disease.
There are different types of angina pectoris, including stable angina, unstable angina, and variant angina. Stable angina occurs when the heart is working harder than usual, such as during physical activity, stress, or exposure to cold temperatures. This type of angina usually goes away within a few minutes of resting or taking medication, such as nitroglycerin. Unstable angina, on the other hand, occurs unexpectedly and may not go away with rest or medication. This type of angina is a medical emergency and requires immediate attention. Variant angina is a rare type of angina that occurs at rest and is caused by a spasm in the coronary arteries.
The diagnosis of angina pectoris is usually based on the patient's medical history, physical examination, and diagnostic tests, such as electrocardiogram (ECG), stress test, echocardiogram, or coronary angiography. Treatment for angina pectoris depends on the severity and type of the condition, as well as the patient's overall health and medical history. Treatment options may include lifestyle changes, such as quitting smoking, losing weight, exercising regularly, and eating a healthy diet. Medications, such as beta-blockers, calcium channel blockers, nitrates, or statins, may also be prescribed to control symptoms and prevent complications. In some cases, invasive procedures, such as angioplasty or bypass surgery, may be necessary to improve blood flow to the heart.
If you experience chest pain or discomfort, it is important to seek medical attention right away. While angina pectoris can be a serious condition, it can be managed with proper treatment and lifestyle changes.
