Angina

Angina pectoris is chest pain or discomfort that occurs when the heart muscle doesn't receive enough blood flow. It's often a symptom of coronary artery disease, which is caused by the buildup of plaque in the coronary arteries.

The chest discomfort in angina pectoris is commonly described as a pressure, squeezing, burning, or tightness in the chest. It's typically located retrosternally (behind the breastbone) and may radiate to the left arm, neck, jaw, shoulder, back, or other areas. The pain or discomfort usually develops gradually and can last for a few minutes, often relieved by rest or medications like nitroglycerin.

Angina pectoris can be classified into stable angina and unstable angina. Stable angina is predictable and often triggered by physical exertion or emotional stress, while unstable angina is more unpredictable and can occur at rest or with minimal exertion. Both types may present with associated symptoms such as shortness of breath, nausea, sweating, and lightheadedness.

It's important to note that angina pectoris is a warning sign of an underlying heart condition, and individuals experiencing chest pain should seek medical attention promptly for a proper diagnosis and appropriate management. If chest pain is sudden, severe, or accompanied by other symptoms like shortness of breath, it may indicate a more serious condition such as acute coronary syndrome (ACS), which requires emergency medical attention.
