Unstable angina

Unstable Angina

Unstable angina (pronounced: un-STAY-bul an-JIE-nuh) is a condition in which the heart does not receive enough blood and oxygen due to partial blockage of the coronary arteries. It is a type of angina and is considered a serious condition as it may lead to a heart attack.

Etymology

The term "unstable angina" is derived from the Latin word "angere" which means to strangle, and the Greek word "ankhone" which means a strangling. This refers to the chest pain that is often associated with the condition.

Symptoms

The symptoms of unstable angina can vary, but often include chest pain or discomfort, shortness of breath, fatigue, and nausea. The chest pain is often described as a feeling of pressure, squeezing, or fullness in the center of the chest. The pain may also spread to the arms, neck, jaw, shoulder, or back.

Causes

Unstable angina is usually caused by the buildup of plaque in the coronary arteries, which can rupture and form a blood clot. This can partially block the blood flow to the heart muscle, leading to symptoms of angina.

Diagnosis

Diagnosis of unstable angina typically involves a physical examination, medical history, and various tests such as an electrocardiogram (ECG), blood tests, and possibly a coronary angiogram.

Treatment

Treatment for unstable angina aims to improve blood flow to the heart muscle and prevent a heart attack. This may involve medications, lifestyle changes, and possibly procedures such as angioplasty and stent placement or coronary artery bypass surgery.
