Overview

Unstable Angina Disease is a serious cardiac condition characterized by sudden and unpredictable chest pain caused by reduced blood flow to the heart muscle. It is considered a medical emergency and a warning sign of an impending heart attack (myocardial infarction).

Unlike stable angina, unstable angina can occur at rest, last longer, and become more intense over time. Immediate medical attention is essential to prevent life-threatening complications.

Types of Unstable Angina

• New-Onset Angina: Chest pain occurring for the first time and increasing in severity

• Spasm of coronary arteries

Complications of Unstable Angina

• Heart attack (myocardial infarction)
• Arrhythmias (irregular heartbeat)
