Understanding Coronary Artery Disease (CAD): A Silent Threat to Millions
Coronary Artery Disease (CAD) is the most common type of heart disease, responsible for countless deaths annually across the USA, UK, and Europe. Known as a “silent killer,” CAD often progresses without obvious symptoms until a major cardiac event like a heart attack occurs.
🔬 What Is CAD?
CAD occurs when the coronary arteries—vital vessels supplying oxygen-rich blood to the heart—become narrowed or blocked due to plaque buildup (atherosclerosis). This reduces blood flow, weakening the heart muscle over time.
⚠️ Key Symptoms to Watch For
- Chest pain or discomfort (angina)
- Shortness of breath
- Fatigue during physical activity
- Heart palpitations
- In extreme cases: heart attack
📊 Global Statistics
According to the WHO, cardiovascular diseases cause over 17.9 million deaths each year, with CAD being a leading factor. In the US alone, over 20 million adults are living with CAD.
🧪 Causes and Risk Factors
- High blood pressure (hypertension)
- High cholesterol
- Smoking
