What is Coronary Artery Disease?

Coronary Artery Disease

Quick Answer

This disease occurs when the coronary arteries become narrowed or blocked, reducing blood flow to the heart. It can lead to chest pain, heart attacks, and other serious heart problems.

Overview

Coronary Artery Disease (CAD) happens when the blood vessels that supply the heart with oxygen-rich blood become narrowed or blocked. This is often due to a buildup of fatty deposits, known as plaque, on the artery walls. As the arteries narrow, the heart may not get enough blood, which can cause symptoms like chest pain or discomfort, especially during physical activity or stress. The condition can develop slowly over many years, often without noticeable symptoms until it becomes serious. For example, a person might feel fine but could still have significant blockages in their arteries. This is why regular check-ups and monitoring are important, especially for those with risk factors like high blood pressure, high cholesterol, or a family history of heart disease. Understanding CAD is crucial because it is a leading cause of heart attacks and can significantly impact a person's quality of life. By recognizing the symptoms and seeking early treatment, individuals can manage the disease effectively. Lifestyle changes, medications, and sometimes surgical procedures can help restore blood flow and reduce the risk of serious complications.

Frequently Asked Questions

What are the main symptoms of Coronary Artery Disease?

The most common symptoms include chest pain or discomfort, shortness of breath, and fatigue during physical activity. Some people may also experience nausea or pain in the arms, back, neck, or jaw.

What causes Coronary Artery Disease?

The main cause is the buildup of plaque in the coronary arteries, which can be influenced by factors like high cholesterol, high blood pressure, smoking, and diabetes. Lifestyle choices such as diet and exercise also play a significant role in its development.

How is Coronary Artery Disease diagnosed?

Doctors typically diagnose CAD through a combination of medical history, physical exams, and tests like electrocardiograms, stress tests, or angiograms. These tests help assess the heart's function and the condition of the coronary arteries.
