Coronary artery disease (CAD) is a heart condition caused by the buildup of plaque in the coronary arteries. This buildup narrows the arteries and reduces blood flow to the heart muscle. If the blood flow becomes severely restricted or blocked, it can lead to a heart attack, which is a serious medical emergency requiring immediate attention.
Understanding coronary artery disease is crucial because it is a leading cause of death worldwide. Many people with CAD do not experience symptoms until a heart attack occurs. Recognizing risk factors, such as high blood pressure, high cholesterol, and smoking, can help in early detection and management of the condition, potentially saving lives.
The coronary arteries play a vital role in the body by supplying blood to the heart. This blood carries oxygen and nutrients that are essential for the heart to function properly. When these arteries are narrowed or blocked, the heart may not receive enough oxygen, which can lead to chest pain (angina) or heart attacks.
In conclusion, coronary artery disease is a significant health concern that affects millions of people. Awareness of its risks and impact on heart health is vital for prevention and early intervention.
