What is Coronary Artery Disease? Understanding Heart Artery Blockage
Coronary Artery Disease (CAD) is a serious condition where the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to the buildup of plaque (atherosclerosis). This reduces blood flow, depriving the heart of oxygen and nutrients. CAD is the leading cause of heart attacks and one of the most common forms of heart disease globally. It can significantly impact daily functioning and overall quality of life if left unmanaged.
Symptoms of Coronary Artery Disease
Recognizing the symptoms of CAD is vital for early intervention and preventing serious complications. Common symptoms include:
- Chest Pain (Angina): Discomfort or tightness in the chest, especially during physical activity or stress.
- Shortness of Breath: Difficulty breathing due to reduced oxygen-rich blood flow to the heart.
- Fatigue: Feeling tired, especially with exertion, due to reduced cardiac efficiency.
- Pain in Other Areas: Discomfort in the arms, neck, jaw, shoulder, or back.
Heart Attack: In some cases, the first sign of CAD may be a heart attack, characterized by severe chest pain, nausea, cold sweats, and lightheadedness.
