Coronary Artery Disease (CAD) is one of the most common heart conditions worldwide. It happens when the coronary arteries—which supply blood and oxygen to the heart muscle—become narrowed or blocked.
Over time, reduced blood flow can increase the risk of chest pain, shortness of breath, heart attack, and other serious complications.
The good news is that many risk factors for CAD can be managed through healthy habits, early awareness, and consistent heart care.
This guide explains the symptoms, common causes, prevention strategies, and ways to support long-term heart health.
What Is Coronary Artery Disease (CAD)?
Coronary Artery Disease occurs when plaque builds up inside the coronary arteries. This buildup narrows the arteries and reduces blood flow to the heart muscle.
As blood flow becomes restricted, the heart may not receive enough oxygen—especially during physical activity or stress.
CAD can develop slowly over many years and may lead to complications if left unmanaged.
Common Symptoms of Coronary Artery Disease
Symptoms can vary depending on the severity of the blockage.
Common symptoms may include:
- Chest pain or pressure (angina)
- Shortness of breath
- Fatigue
- Dizziness
- Weakness during activity
- Irregular heartbeat
Some people may not notice symptoms until the condition becomes more serious.
What Causes Coronary Artery Disease?
CAD is usually linked to plaque buildup and long-term strain on the heart.
Common risk factors include:
- High cholesterol
- High blood pressure
- Smoking
- Diabetes
- Obesity
- Physical inactivity
- Chronic stress
- Poor diet
- Family history
