Unstable Angina

Introduction

Unstable angina is a type of chest pain that occurs when the blood flow to the heart is reduced. It is usually caused by a blockage in the coronary arteries, which can be caused by a build-up of plaque (a mixture of fat, cholesterol, and other substances) on the inner walls of the arteries. Unstable angina is a serious condition that requires prompt medical attention, as it can be a warning sign of a heart attack. The main symptoms of unstable angina are chest pain, shortness of breath, and a feeling of tightness or pressure in the chest. If you are experiencing these symptoms, you should seek medical attention immediately.

Symptoms

  • Chest pain or discomfort
  • Shortness of breath
  • Nausea or vomiting
  • Sweating
  • Fatigue
  • Lightheadedness or dizziness
  • Rapid or irregular heartbeat

Causes

Unstable angina is usually caused by a blockage in the coronary arteries. These arteries supply blood to the heart muscle. A blockage can be caused by a build-up of plaque on the inner walls of the arteries. Plaque is made up of fat, cholesterol, and other substances. As the plaque builds up, it can narrow the arteries and reduce blood flow to the heart.

Other factors that can increase the risk of developing unstable angina include:

  • High blood pressure
  • High cholesterol
  • Diabetes
  • Smoking
  • Obesity
  • Physical inactivity
  • Age (risk increases as you get older)
  • Family history of heart disease
