Understanding the Most Common Form of Heart Disease
Coronary Artery Disease (CAD) is the most common type of heart disease and the leading cause of death worldwide. What makes it especially concerning is that it often develops quickly. Many people feel healthy for years before symptoms appear.
Because CAD progresses slowly, awareness and early prevention is critical.
What is Coronary Artery Disease?
Coronary Artery Disease occurs when the arteries that supply blood to the heart become narrowed or blocked. This happens due to plaque buildup — a combination of cholesterol, fat, calcium, and inflammatory cells — along the artery walls.
As plaque accumulates, blood flow to the heart decreases. If a blockage becomes severe or a clot forms suddenly, it can lead to a heart attack.
This process usually develops over many years.
Who is at risk?
Non-modifiable factors:
Increasing age
Family history or heart disease
Modifiable factors:
High LDL (bad) cholesterol
High blood pressure
Smoking
Diabetes
Physical inactivity
Chronic stress
Poor sleep
You do not have to “look unhealthy” to be at risk. Many individuals with normal weight may have elevated cholesterol, high blood pressure, or other underlying risk factors.
Common Symptoms
CAD may not cause symptoms at first. When symptoms do appear, they may include:
Chest pressure or tightness
Shortness of breath
Pain in the jaw, neck, shoulder, or arm
Fatigue with activity
A sudden blockage can cause a heart attack. Severe chest pain, sweating, nausea, or shortness of breath require immediate medical attention.
Prevention and Treatment
Maintaining healthy cholesterol and blood pressure levels
Engaging in regular physical activity
Following a heart-healthy diet
Avoiding smoking
Managing stress
Doctors may prescribe medications such as statins or blood pressure treatments when necessary. In more advanced cases, procedures such as angioplasty or bypass surgery may be required.
Coronary Artery Disease develops gradually and may not cause symptoms until it becomes serious. Routine health screenings and attention to cardiovascular risk factors are essential.
Understanding your numbers — including cholesterol and blood pressure — is an important step in protecting long-term heart health.
Early awareness allows for early action.
